Description

FIELD OF THE INVENTION



[0001] The present invention relates to the field of communications, and more particularly to a method, a base station (BS), and a user terminal for implementing uplink resource indication.

BACKGROUND OF THE INVENTION



[0002] Time Division Duplex (TDD) is a radio transmission mode on radio channels. In the TDD mode, the transmission and reception are conducted in a time division manner, that is, the radio transmission based on the TDD mode realizes the time division multiplexing of uplink and downlink channels. The TDD mode is implemented by repeating Time Division Multiple Access (TDMA) frame structures periodically in time domains. For example, in Long Term Evolution (LTE), the 3GPP LTE has two TDD frame structures. The first frame structure is as shown in FIG. 1, in which a radio frame is composed by 20 slots, a period of a frame is 10 ms, and every two slots form a subframe (SF). The second frame structure is as shown in FIG. 2, in which a period of a frame is also 10 ms, a frame is divided into two half-frames, each half-frame is composed by seven SFs, a guard interval is inserted between every two SFs, and a guard period (GP) is formed by a downlink pilot time slot (DwPTS), a GP, and an uplink pilot time slot (UpPTS).

[0003] In the frame structure in the TDD mode, one frame includes several SFs or slots. The SFs may be classified into uplink SFs and downlink SFs, and a TDD system may use a transfer point to change the SF types flexibly. For example, the current 3GPP LTE standard specifies various SF ratios in the two frame structures. FIG. 3 is a schematic view of various uplink and downlink SF ratios in the first frame structure, in which the ratios in one frame are illustrated. FIG. 4 is a schematic view of various uplink and downlink SF ratios in the second frame structure, in which the ratios in one and a half frames are illustrated. A table of uplink and downlink SF ratios (Table 1) can be concluded from figures 3 and 4. Table 1 lists the situation of one transfer point, that is, the situation that the uplink and downlink SFs have only one type transfer.
Table 1
Frame StructureUplink and Downlink SF Ratios (Downlink: Uplink)
First Frame Structure 4:1, 3:2, 9:1, 6:4, 7:3, 8:2, 10: 0, 2:2, 4:2, 2:3, 1:4
Second Frame Structure 6:1, 5:2, 4:3, 3:4, 2:5, 1:6


[0004] According to different service requirements, the TDD system needs to indicate the uplink resources to which some uplink instructions are directed in the uplink instructions. For example, in downlink transmission of a 3GPP Evolved Universal Terrestrial Radio Access (E-UTRA) system, an Orthogonal Frequency Division Multiplexing (OFDM) technology is employed to realize multiple access. The OFDM is a multi-carrier communication technology. In a multi-carrier communication system, different time domain and frequency domain resources are granted to different users to realize multiplexing of time-frequency resources by multiple users. Here, the time-frequency resources may be granted by carrying resource grant indications of corresponding uplink SFs (ul grant) in downlink control signaling of a user. A ul grant may contain different contents. Table 2 lists the content of a ul grant.

Multi-antenna Technology 2 Determined by multi-user MIMO and uplink multi-antenna technology, 2 bits
User Terminal Identity + Cyclic Redundancy Check (CRC) 20 16-24-bit CRC


[0005] Generally, a base station (BS) adopts downlink SFs to send the ul grant as shown in Table 2. After receiving the ul grant, each user determines whether the user identity in the ul grant is consistent with the identity of each user itself; and if they are consistent, the user grants the resources according to the ul grant. Thus, the resources can be granted to all users. For a user, when the downlink SFs are more than the uplink SFs, each of the downlink SFs is mapped to one uplink SF, that is, the downlink SF may be adapted to send a ul grant for one uplink SF. However, the frame structure in the TDD system may be asymmetrical in terms of the uplink and downlink ratio, as shown in Table 1, that is, one downlink SF may be corresponding to multiple uplink SFs, so that the corresponding uplink SF cannot be determined according to one ul grant. In this case, a downlink SF needs to be adapted to send multiple ul grants, so that one downlink SF is corresponding to multiple uplink SFs, and the ul grants will be sent separately. In other words, for the same user, if it is determined that n uplink SFs are required after scheduling, n corresponding ul grants exist, which will be transmitted repeatedly. Thus, the information such as the user identity is also repeatedly transmitted for n times, resulting in the waste of transmission resources such as signaling and channels.

[0006] It is known from the above analysis that the existing method for implementing uplink resource indication in the TDD system cannot indicate the uplink resources corresponding to the ul grants precisely, which may cause the waste of the resources and lead to a low utilization of the resources.

[0007] 3GPP contribution R1-072931 titled as "Timing relationship between the DL control signaling and associated sub-frames" discloses a timing relationship between the DL control signaling and associated sub-frames as below:
Ratio of UL/DLTS1TS2TS3TS4TS5TS6TS0

5:2 - - - - - TS1 & TS2 TS3, TS4 & TS5
6:1 - - - - - - TS1, TS2, TS3, TS4, TS5 & TS6


[0008] When there are more UL sub-frames than DL sub-frames, for example, when the ratio of UL/DL is 4:3, at least one more bit is needed for UL schedule grant signaling in TS0 to indicate the associated UL sub-frames: TS3 or TS4. When the ratio of UL/DL is 6:1, 3 more bits are needed to indicate the UL sub-frames.

[0009] 3GPP contribution R1-072998 titled as "Control signaling considerations for EUTRA TDD" discloses control signaling considerations for EUTRA TDD. Especially, section 2 discusses about DL control signaling resources and capacity, wherein one UL/DL scheduling grant allocates one UL/DL subframe for one UE in a known UL/DL subframe position as dynamic scheduling by L1/L2 control signaling.

DETAILED DESCRIPTION OF THE EMBODIMENTS



[0024] In order to make the objectives, technical solutions, and beneficial effects of the present invention comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] A method according to an embodiment of the present invention includes the following steps. An uplink resource index is carried in a ul grant, in which the uplink resource index is corresponding to at least one uplink resource in terms of indication. Then, the ul grant is sent.

[0026] In the embodiment of the present invention, the uplink resource may be a time domain resource such as an uplink slot or an uplink SF, or other resource blocks such as a frequency domain resource block. The uplink SF is taken as an example below to illustrate the present invention.

[0027] FIG. 5 is a schematic flow chart of a method for implementing uplink resource indication according to a first embodiment of the present invention.

[0028] In Step 501, a corresponding relation between an uplink resource index and at least one uplink resource in terms of indication is established.

[0029] The method for establishing the corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication includes the following steps. The at least one uplink resource is combined into one group, and the uplink resources in each group are not completely the same. Each group is corresponding to an uplink resource index, so as to establish the corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication.

[0030] In this embodiment, uplink resource indexes of different bits are applied to different frame structures, so that different corresponding relations between the uplink resource index and at least one uplink SF can be established. The establishing the corresponding relation between the uplink resource index and the at least one uplink SF in terms of indication in different circumstances is described in detail below. Persons skilled in the art should understand that only some specific examples of the technical solutions according to the embodiments of the present invention are illustrated below, and the present invention is not limited thereto.

[0031] In a first case, for the frame structure shown in FIG. 2, the ul grant supports the indication of discontinuous uplink SFs, and the uplink resource index has four bits. Table 3 lists a combination in the first case. In this combination, one or two uplink SFs are combined into one group.

[0032] In a second case, for the frame structure shown in FIG. 2, the ul grant supports the indication of continuous uplink SFs, and the uplink resource index has three bits. Table 4 lists a combination in the second case. In this combination, one or two uplink SFs are combined into one group.

[0033] In a third case, for the frame structure shown in FIG. 1, the uplink resource index has four bits. For the simplicity of illustration, only the uplink SFs are considered. In addition, for the convenience of illustration, when there is only one uplink SF, the uplink SF is represented as ULSF1; and when there are two uplink SFs, the two uplink SFs are represented as ULSF1 and ULSF2 respectively. The representation of other uplink SFs is similar. Table 5 lists a combination in the third case.

[0034] In a fourth case, for the frame structure shown in FIG. 1, the ul grant supports the indication of continuous uplink SFs, and the uplink resource index has three bits. Table 6 lists a combination in the fourth case.

[0035] In Step 502, the uplink resource index is carried in the ul grant, and the uplink resource index is corresponding to at least one uplink resource.

[0036] In this embodiment, the ul grant is that of the same user listed in Table 2, and the specific content of the ul grant is shown in Table 7.

[0037] In Step 503, the ul grant carrying the uplink resource index is sent.

[0038] In this embodiment, the ul grant carrying the uplink resource index is sent in a downlink SF.

[0039] In this embodiment, the optimal 3-bit or 4-bit uplink resource index is adapted to indicate the uplink SF, and for the convenience of illustration, only the combination of one or two uplink SFs is described. Persons skilled in the art should understand that the embodiment of the present invention is not limited to the corresponding relations between the uplink resource index and the uplink SF in terms of indication listed in Table 3 to Table 7.

[0040] After receiving the ul grant carrying the uplink resource index from a BS, a user terminal resolves the uplink resource index from the ul grant, and performs the resource grant on the at least one uplink resource corresponding to the uplink resource index according to the corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication obtained in advance. Here, after the BS establishes the corresponding relation in terms of indication, the user terminal may obtain the corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication through static configuration or by dynamically acquiring from the BS.

[0041] In this embodiment, by carrying the uplink resource index in the ul grant, one ul grant of a user may indicate the resource grant of multiple uplink SFs. Thus, when an asymmetrical resource grant is performed in the TDD mode, especially when the uplink SFs are more than the downlink SFs, the corresponding relation between the ul grant and the uplink SFs can be established. This embodiment realizes accurate indication of the at least one uplink resource through the uplink resource index, prevents repeated transmission of the same information in multiple uplink resources, effectively reduces the signaling overhead, and increases the resource utilization.

[0042] FIG. 6 is a schematic flow chart of a method for implementing uplink resource indication according to a second embodiment of the present invention.

[0043] In Step 601, all uplink resources are grouped in at least one uplink resource set in advance.

[0044] In this embodiment, all of the uplink resources are grouped into at least one uplink resource set according to the corresponding relation between the downlink SF for sending the ul grant and the uplink SFs in terms of indication.

[0045] In this embodiment, the frame structure in FIG. 2 is adopted, and the corresponding relation between the downlink SFs and the uplink SF set in terms of indication listed in Table 8 is set in advance. For example, when the uplink and downlink SF ratio is 4:3, if SF6 is adapted to send the ul grant carrying the uplink resource index, the ul grant is directed to SF2; and if SFO is adapted to send the ul grant carrying the uplink resource index, the ul grant is directed to SF3 and SF4.
Table 8

5:2 - - - - - SF1 and SF2 SF3, SF4, and SF5
6:1 - - - - - - SF1, SF2, SF3, SF4, SF5, and SF6


[0046] In Step 602, a corresponding relation between an uplink resource index and at least one uplink resource in terms of indication is established.

[0047] The corresponding relation between the uplink resource index and the at least one uplink resource may be established as follows. The at least one uplink resource in each uplink resource set is combined into one group, and the uplink resources in each group are not completely the same. Each group in the same uplink resource set is corresponding to one uplink resource index, so as to establish the corresponding relation between the uplink resource index and at least one uplink resource in the same uplink resource group in terms of indication.

[0048] In this embodiment, for the frame structure shown in FIG. 2, according to the corresponding relation between the downlink SFs and the uplink SF set listed in Table 8, the uplink resource indexes in different bits are adapted to establish the corresponding relation between different uplink resource indexes and at least one uplink SF in terms of indication. Two circumstances are described as follows.

[0049] In a first case, for the frame structure shown in FIG. 2, the uplink resource index has four bits. Table 9 lists a combination in the first case.

[0050] In a second case, for the frame structure shown in FIG. 2, the ul grant supports the indication of discontinuous uplink SFs, and the uplink resource index has three bits. Table 10 lists a combination in the second case.

[0051] Certainly, in this embodiment, the frame structure shown in FIG. 1 may also be adopted. Thereby, the corresponding relation between the downlink SFs and the uplink resource set listed in Table 11 may be set in advance in Step 601.

[0052] For the frame structure shown in FIG. 1, according to the corresponding relation between the downlink SFs and the uplink SF set listed in Table 11, the uplink resource indexes in different bits are adapted to establish the corresponding relation between the uplink resource indexes and at least one uplink SF in terms of indication. Two circumstances are described as follows.

[0055] In Step 603, the uplink resource index is carried in the ul grant, and the uplink resource index is corresponding to at least one uplink resource.

[0056] In this embodiment, the uplink resource index for indicating the uplink resource is carried in another ul grant. The specific content is shown in Table 14.

[0057] In Step 604, the ul grant carrying the uplink resource index is sent.

[0058] In this embodiment, all uplink resources are grouped into at least one uplink resource set, the uplink SF set corresponding to the ul grant is preliminarily determined according to the downlink SF for sending the ul grant, and the specific uplink resources are indicated according to the uplink resource index added in the ul grant.

[0059] In this embodiment, according to the preset corresponding relation between the downlink SFs and the uplink SF set, all of the uplink SFs are grouped into at least one uplink SF set. For uplink slots, according to the preset corresponding relation between the downlink slot and the uplink slot set, all of the uplink SFs are grouped into at least one uplink slot set. In this case, the user terminal needs to obtain the mode for grouping the uplink resource set statically or dynamically, and the indicated uplink resource is determined according to the obtained uplink resource set and the uplink resource index.

[0060] In the current 3GPP LTE standard, the resource grant is performed in a downlink acknowledgement (DLACK) mode, and the resources are corresponding to the ul grants one by one. When the resource grant of multiple uplink resources is represented by one ul grant, data packets of the uplink resources are corresponding to one acknowledgement channel, which may carry information of only two bits. Therefore, in this embodiment, one ul grant can indicate the resource grant of at most two uplink resources.

[0061] This embodiment realizes accurate indication of the at least one uplink resource through the uplink resource index, prevents repeated transmission of the same information in multiple uplink resources, effectively reduces the signaling overhead, and increases the resource utilization.

[0062] FIG. 7 is a schematic structural view of a BS for implementing uplink resource indication according to a third embodiment of the present invention. The BS includes an index carrying module 702 and an instruction sending module 701.

[0063] The index carrying module 702 is adapted to carry an uplink resource index in a ul grant, in which the uplink resource index is corresponding to at least one uplink resource in terms of indication.

[0064] The instruction sending module 701 is adapted to send the ul grant generated by the index carrying module 702.

[0065] The BS further includes a mapping module 703.

[0066] The mapping module 703 is adapted to establish a corresponding relation between an uplink resource index and at least one uplink resource in terms of indication.

[0067] This embodiment realizes accurate indication of the at least one uplink resource through the uplink resource index, prevents repeated transmission of the same information in multiple uplink resources, effectively reduces the signaling overhead, and increases the resource utilization.

[0068] FIG. 8 is a schematic structural view of a user terminal according to a fourth embodiment of the present invention. The user terminal includes an instruction receiving module 801, an instruction resolving module 802, and an execution module 803.

[0069] The instruction receiving module 801 is adapted to receive a ul grant from a BS, in which the ul grant carries an uplink resource index, and the uplink resource index is corresponding to at least one uplink resource in terms of indication.

[0070] The instruction resolving module 802 is adapted to resolve the uplink resource index from the ul grant received by the instruction receiving module 801.

[0071] The execution module 803 is adapted to obtain the at least one uplink resource corresponding to the uplink resource index resolved by the instruction resolving module 802 according to a corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication obtained in advance, and perform the resource grant on the obtained at least one uplink resource.

[0072] This embodiment realizes accurate indication of the at least one uplink resource through the uplink resource index, prevents repeated transmission of the same information in multiple uplink resources, effectively reduces the signaling overhead, and increases the resource utilization.

[0073] As shown in FIG. 9, a radio frame is composed by 20 slots, a period of a frame is 10 ms, a frame is divided into two half-frames, each half-frame is composed by five SFs, the first half-frame includes SF0-SF4, and the second half-frame includes SF5-SF9. SF1 and SF6 are respectively formed by a special downlink pilot time slot (DwPTS), a guard period (GP), and an uplink pilot time slot (UpPTS), and serve as transfer points of uplink and downlink SFs. SF6 may also not be configured as a transfer point. Thereby, the entire frame is used as a downlink frame.

[0074] In the frame structure in the TDD mode, one frame includes several SFs or slots. The SFs may be classified into uplink SFs and downlink SFs, and a TDD system may use a transfer point to transfer the SF types flexibly. For example, in the current 3GPP LTE standard, different SF grant ratios are specified. FIG. 10 is a schematic view of various uplink and downlink SF ratios in the frame structure shown in FIG. 9. FIG. 10 lists seven configuration results of a frame. The frame includes ten SFs, namely SF0-SF9. In different configurations, the uplink and downlink SF ratios in a frame are different. A table of uplink and downlink SF ratios (Table 15) is concluded from FIG. 10. Table 15 lists the circumstances of one and two transfer points.

[0075] FIG. 11 is a schematic flow chart of a method for implementing uplink resource indication according to a fifth embodiment of the present invention.

[0076] In Step 1101, a corresponding relation between an uplink resource index and at least one uplink resource in terms of indication is established.

[0077] The method for establishing the corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication is as follows. The at least one uplink resource is combined into one group, and the uplink resources in each group are not completely the same. Each group is corresponding to an uplink resource index, so as to establish the corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication.

[0078] In this embodiment, uplink resource indexes of different bits are used for different frame structures, so different corresponding relations between the uplink resource index and at least one uplink SF can be established. The establishing the corresponding relation between the uplink resource index and the at least one uplink SF in terms of indication in different situations are described in detail below. Persons skilled in the art should understand that only some specific examples of the technical solutions according to the embodiment of the present invention are described below, and the present invention is not limited thereto.

[0079] For the frame structure shown in FIG. 10, the ul grant supports the indication of continuous uplink SFs, and the uplink resource index has three bits. Table 16 lists a combination in a first case. In this combination, one or two uplink SFs are combined into one group.

[0080] In Step 1102, the uplink resource index is carried in the ul grant, and the uplink resource index is corresponding to at least one uplink resource.

[0081] In this embodiment, the ul grant is that of the same user listed in Table 2, and the specific content of the ul grant is as listed in Table 17.

[0082] In Step 1103, the ul grant carrying the uplink resource index is sent.

[0083] In this embodiment, the ul grant carrying the uplink resource index is sent in a downlink SF.

[0084] In this embodiment, the optimal 3-bit uplink resource index is adapted to indicate the uplink SF, and for the convenience of illustration, only the combination of one or two uplink SFs is described. Persons skilled in the art should understand that the embodiment of the present invention is not limited to the corresponding relations between the uplink SF index and the uplink SF in terms of indication listed in Table 3 and Table 4.

[0085] After receiving the ul grant carrying the uplink resource index from a BS, a user terminal resolves the uplink resource index from the ul grant, and performs the resource grant on the at least one uplink resource corresponding to the uplink resource index according to the corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication obtained in advance. Here, after the BS establishes the corresponding relation in terms of indication, the user terminal may obtain the corresponding relation between the uplink resource index and the at least one uplink resource in terms of indication through static configuration or by dynamically acquiring from the BS.

[0086] In this embodiment, by carrying the uplink resource index in the ul grant, one ul grant of a user may indicate the resource grant of multiple uplink SFs. Thus, when an asymmetrical resource grant is performed in the TDD mode, especially when the uplink SFs are more than the downlink SFs, the corresponding relation between the ul grant and the uplink SFs can be established. This embodiment realizes accurate indication of the at least one uplink resource through the uplink resource index, prevents repeated transmission of the same information in multiple uplink resources, effectively reduces the signaling overhead, and increases the resource utilization.

[0087] FIG. 12 is a schematic flow chart of a method for implementing uplink resource indication according to a sixth embodiment of the present invention.

[0088] In Step 1201, all uplink resources are grouped in at least one uplink resource set in advance.

[0089] In this embodiment, all of the uplink resources are grouped into at least one uplink resource set according to the corresponding relation between the downlink SF for sending the ul grant and the uplink SFs in terms of indication.

[0090] In this embodiment, the frame structure in FIG. 10 is adopted, and the corresponding relation between the downlink SFs and the uplink SF set in terms of indication listed in Table 18 is set in advance. For example, when the uplink and downlink SF ratio (UL: DL) is 3:1, if SF0 is adapted to send the ul grant carrying the uplink resource index, the ul grant is directed to SF4 of the current period and SF2* of the next period; and if SF1 is adapted to send the ul grant carrying the uplink resource index, the ul grant is directed to SF2* and SF3* of the next period.
Table 18
Uplink and Downlink SF Ratio (UL:DL)SF0SF1SF2SF3SF4
3:1 SF4 and SF2* SF2* and SF3* - - -


[0091] In Step 1202, a corresponding relation between an uplink resource index and at least one uplink resource in terms of indication is established.

[0092] The corresponding relation between the uplink resource index and the at least one uplink resource may be established as follows. The at least one uplink resource in each uplink resource set is combined into one group, and the uplink resources in each group are not completely the same. Each group in the same uplink resource set is corresponding to one uplink resource index, so as to establish the corresponding relation between the uplink resource index and at least one uplink resource in the same uplink resource group in terms of indication.

[0093] In this embodiment, according to the corresponding relation between the downlink SF and the uplink SF set, the uplink resource indexes in different bits are adapted to establish the corresponding relation between different uplink resource indexes and at least one uplink SF in terms of indication. For example, for the frame structure shown in FIG. 10, the uplink resource index has two bits; and according to the corresponding relation listed in Table 18, a combination listed in Table 19 is obtained.

[0094] In Step 1203, the uplink resource index is carried in the ul grant, and the uplink resource index is corresponding to at least one uplink resource.

[0095] In this embodiment, the uplink resource index for indicating the uplink resource is carried in another ul grant. The specific content is shown in Table 20.

[0096] In Step 1204, the ul grant carrying the uplink resource index is sent.

[0097] In this embodiment, all uplink resources are grouped into at least one uplink resource set, the uplink SF set corresponding to the ul grant is preliminarily determined according to the downlink SF for sending the ul grant, and the specific uplink resources are indicated according to the uplink resource index added in the ul grant.

[0098] In this embodiment, according to the preset corresponding relation between the downlink SF and the uplink SF set, all of the uplink SFs are grouped into at least one uplink SF set. For uplink slots, according to the preset corresponding relation between the downlink slot and the uplink slot set in terms of indication, all of the uplink SFs are grouped into at least one uplink slot set. In this case, the user terminal needs to obtain the mode for grouping the uplink resource set statically or dynamically, and the indicated uplink resource is determined according to the obtained uplink resource set and the uplink resource index.

[0099] In the current 3GPP LTE standard, the resource grant is performed in a DLACK mode, and the resources are corresponding to the ul grants one by one. When the resource grant of multiple uplink resources is represented by one ul grant, data packets of the multiple uplink resources are corresponding to one acknowledgement channel, which may carry information of only two bits. Therefore, in this embodiment, one ul grant can indicate the resource grant of at most two uplink resources. If two many packets are indicated, in the retransmission, the packets cannot be terminated at the same time, which makes the subsequent scheduling more complicated. Therefore, the comprehensive consideration of resource grant of two uplink resources is a reasonable processing mode.

[0100] This embodiment realizes accurate indication of the at least one uplink resource through the uplink resource index, prevents repeated transmission of the same information in multiple uplink resources, effectively reduces the signaling overhead, and increases the resource utilization.

[0101] All or a part of the content of the technical solutions according to the embodiments may be implemented through software programming. The software program is stored in a readable storage media, for example, a hard disk, an optical disk, or a floppy disk in a computer.

[0102] It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims.
