Description

CROSS-REFERENCE TO RELATED APPLICATION



[0001] This application claims a priority to Chinese Patent Application No. 201710860820.1, filed in China on September 21, 2017, the disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD



[0002] The present disclosure relates to the field of communication technology, and in particular to a resource block group (RBG) partitioning method and user equipment.

BACKGROUND



[0003] For a downlink in a communication system, RBG-based resource allocation is supported. The RBG refers to a group of continuously distributed resource blocks (RBs). An RBG size may be represented by P, wherein the P is determined by a downlink system bandwidth

For example, in case that the

is less than or equal to 10, the P is equal to 1; in case that the

is greater than or equal to 11 and less than or equal to 26, the P is equal to 2; and so on. A quantity of RBGs corresponding to the entire downlink system bandwidth

is

wherein ┌ ┐ refers to rounding up to an integer, and the RBGs are numbered in ascending order of frequency and have a non-increasing RBG size.

[0004] However, in communication systems, such as a new radio (NR) communication system, user equipment may not support full-bandwidth transmission and reception. Therefore, a concept of carrier band width part (BWP) is introduced in the NR communication system. The BWP is a continuous physical resource block (PRB) subset of a carrier. The user equipment only transmits and receives in an active BWP, and RBs in the BWP are numbered starting from 0. If the RBG partitioning method in the related art is still adopted, in case that the BWPs of different user equipment overlap, a situation in which the RBG partitioning mismatch may occur. For example, as shown in Fig.1, after RBG#3 of user equipment 3 is occupied, RBG#1 of user equipment 2 may not be used, and since boundary of RBG#1 of the user equipment 2 is not aligned with boundary of RBG#3 of user equipment 3, some RBs may not be allocated by using an RBG-based mechanism. It could be seen that the use of the RBG partitioning method in the related art will result in a relatively low resource-reuse efficiency.

Apparently, the described embodiments are some embodiments of the present disclosure, instead of all the embodiments. Based on the embodiments of the present disclosure, all other embodiments derived by a person of ordinary skill in the art without any creative efforts shall fall within the scope of the present disclosure.

[0028] Referring to Fig.2, Fig.2 is a schematic diagram of a network structure to which embodiments of the present disclosure are applicable. As shown in Fig.2, user equipment (UE) 21 and a network-side device 22 are included. The user equipment 21 may be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile Internet device (MID), or a wearable device, it should be noted that the specific type of the user equipment 21 is not limited in the embodiments of the present disclosure.

It should be noted that a specific type of the network side device 22 is not limited in the embodiments of the present disclosure.

[0029] Referring to Fig.3, Fig.3 is a flowchart of an RBG partitioning method provided in some embodiments of the present disclosure. As shown in Fig.3, the method includes the following steps.

Step 301 includes: determining an RB included in a first RBG in a BWP;

Step 302 includes: determining an RB included in other RBG in the BWP according to a pre-acquired RBG size, wherein the other RBG is an RBG other than the first RBG in the BWP.



[0030] The first RBG in the BWP may be the first RBG on a side of the BWP, such as, the first RBG on the low frequency side, or the first RBG on the high frequency side. The first RBG on the low frequency side may be understood as the first RBG in the BWP in ascending order of frequency, that is, the RBs included in the RBG are RBs with the lowest frequencies in the BWP; while the first RBG on the high frequency side may be understood as the first RBG in the BWP in descending order of frequency, that is, the RBs included in the RBG are RBs with the highest frequency in the BWP. In addition, in some embodiments of the present disclosure, the first RB in the BWP is also the first RB on one side, such as, the first RB on the low frequency side, or the first RB on the high frequency side. The first RB on the low frequency side may be understood as the RB with the lowest frequency in the BWP, while the first RB on the high frequency side can be understood as the RB with the highest frequency in the BWP. For a first RB of a carrier bandwidth, a reference may be made to the first RB in the BWP, which is not described here.

[0031] In addition, the determined RB included in the first RBG in the BWP may be determined by the user equipment according to a notification message transmitted by the network side, or determined by the user equipment according to a pre-acquired determination rule, which is not limited in the embodiments of the present disclosure. The quantity of RBs included in the first RBG may be less than or equal to the RBG size. The above RBG size may be calculated by the user equipment according to a configured bandwidth or may be configured on the network side, which is not limited to the embodiments of the present disclosure.

[0032] The step 302 may include: subtracting the quantity of RBs in the first RBG from the quantity of RBs in the BWP and then dividing the result by P to obtain RBs included in other RBGs. It should be noted that, in the embodiments of the present disclosure, the RBG size may be represented by P.

[0033] For example: the quantity of RBs in the BWP is N, and the quantity of RBs in the first RBG is P1, then the quantity of RBGs, except the first RBG, is

The size of each of

RBGs is P. If (N-P1) mod P> 0, the size of one of the RBGs is

wherein ┌ ┐ is rounding up to an integer, └ ┘ is rounding down to an integer, and the mod is a remainder operation. For example, as shown in Fig.4, the quantity N of RBs included in the BWP is 106, the size P of the RBG is 8, and the size PI of the first RBG is 6, then in addition to RBG0, there are

wherein the size of each of 12 RBGs are 8 and the size of the remaining RBG is 4.

[0034] It should be noted that, through the above steps, the RBs included in the first RBG in the BWP may be determined firstly, and other RBGs are partitioned according to the RBG size. In this way, in case that BWPs of a plurality of user equipment overlap, BWP RBG partitioning for the plurality of user equipment are matched in terms, that is, the RBG partitioning of different BWPs in the carrier are matched, thereby improving resource usage efficiency. For example, as shown in Fig.5, user equipment 2 firstly determines the RBs included in the first RBG (RBG#0), and other RBGs (RBG#1 to RBG#6) are partitioned according to the above RBG size, so that RBGs of the user equipment 2 and user equipment 3 are matched to improve resource utilization efficiency.

[0035] In an optional embodiment, the first RBG is a first RBG on a low frequency side of the BWP; the determining the RB included in other RBG in the BWP according to the pre-acquired RBG size includes: determining the RB included in other RBG in the BWP in ascending order of frequency according to the pre-acquired RBG size; or, the first RBG is a first RBG on a high frequency side of the BWP; the determining the RB included in other RBG in the BWP according to the pre-acquired RBG size includes: determining the RB included in other RBG in the BWP in descending order of frequency according to the pre-acquired RBG size;

[0036] This embodiment may flexibly determine RBs included in the first RBG and the RBs included in other RBGs. Therefore, the flexibility of the RBG partitioning is improved, so as to adapt to different communication services and different communication scenarios, and improve the communication performance of user equipment.

[0037] In another optional embodiment, determining the RB included in the first RBG in the BWP includes: determining the RB included in the first RBG in the BWP according to a notification message transmitted by a network side.

[0038] The notification message may be configured to notify the user equipment of parameters for determining the RB included in the first RBG. After the user equipment acquires the notification message, the user equipment may accurately determine the RB included in the first RBG. Moreover, because the notification message is transmitted by the network side, it may be ensured that the RBG partitioning of the plurality of user equipment matches in case that BWPs of a plurality of user equipment overlap. Because the network side knows the BWP of each user equipment, the network side may make the RBGs partitioned by various user equipment matched through the above notification message, to improve resource usage efficiency.

[0039] Optionally, the notification message includes: a starting position of the first RBG, an ending position of the first RBG, a quantity of the RB included in the first RBG, or a starting position of a second RBG in the BWP.

[0040] The RB included in the first RBG may be determined flexibly through the above notification message.

[0041] In addition, the notification message including the starting position of the first RBG, the ending position of the first RBG, the quantity of the RB included in the first RBG, or the starting position of a second RBG in the BWP may be understood as the notification message carrying the information, that is, in the embodiments of the present disclosure, the notification message includes, but is not limited to, the starting position of the first RBG, the ending position of the first RBG, the quantity of RBs included in the first RBG, or the starting position of the second RBG in the BWP. For example, in addition to the information, the above notification message may also include other information configured by the network side for the user equipment. Of course, the other information may not be included, that is, only the above mentioned information is included. The notification message may be a message newly defined in the embodiment of the present disclosure, or the notification message may be a message defined in a protocol in related art. In the embodiments of the present disclosure, the starting position of the first RBG, the ending position of the first RBG, the quantity of RBs included in the first RBG, or the starting position of the second RBG in the BWP may be added to the message in the related art, to reduce transmission overhead.

[0042] The determining the RB included in the first RBG in the BWP according to the notification message transmitted by the network side may include:

taking an RB belonging to the BWP among a quantity P of RBs starting from the starting position of the first RBG as the RB included in the first RBG in case that the notification message includes the starting position of the first RBG, wherein the P is the RBG size; or

taking at least one RB starting from the first RB in the BWP as the RB included in the first RBG in case that the notification message includes the ending position of the first RBG, wherein an ending position of the at least one RB is the ending position of the first RBG; or

taking at least one RB starting from the first RB in the BWP as the RB included in the first RBG in case that the notification message includes the quantity of the RB included in the first RBG, wherein a quantity of the at least one RB is the quantity of the RB included in the first RBG; or

taking at least one RB starting from the first RB in the BWP as the RB included in the first RBG in case that the notification message includes the starting position of the second RBG, wherein an ending position of the at least one RB is an RB immediately previous to the starting position of the second RBG.



[0043] Hereinafter, the above implementation of determining the first RBG is exemplified by assuming that the BWP of the user equipment includes a quantity N of RBs, which are numbered RB0, RB1, ..., RBN-1 in ascending order of frequency, and the network side notifies the user equipment of the first RBG position on the low frequency side of the BWP.

[0044] Mode 1, the network side notifies the starting position of the first RBG.

[0045] The network side notifies the starting RB number of the first RBG. For example, the starting RB number Istart ranges from -N1, -N1 + 1, ..., 0, wherein the N1=P-1 and the P is the RBG size. The size of the first RBG is P + Istart, and RB0 to RBP+Istart are included.

[0046] Mode 2, the network side notifies the ending position of the first RBG.

[0047] The network side notifies the ending RB number of the first RBG. Specifically, the ending RB number Iend ranges from 0, 1, ..., N2, wherein the N2=P-1, and the P is the RBG size. The size of the first RBG is Iend+1, and RB0 to RBIend are included.

[0048] Mode 3, the network side notifies the size of the first RBG.

[0049] The network side notifies the size PI of the first RBG, then the RBs included in the first RBG are RB0 to RBP1, and PI ranges from 1, 2, ..., P, and the P is the RBG size.

[0050] Mode 4, the network side notifies the starting position of the second RBG.

[0051] The network side notifies the starting RB number of the second RBG. For example, the starting RB number I'start ranges from 1, 2, ..., P, the RBs included in the first RBG are the first I'start RBs, i.e., RB0 to RBI'start-1 are included.

[0052] The RBG size P = 4 is assumed, as shown in Fig.6, Fig.6 is a schematic diagram of the position and the size of the first RBG in case that Istart = -3, -2, -1, 0 / Iend = 0, 1, 2, 3 / PI = 1, 2, 3, 4 / I'start = 1, 2, 3, 4. In case that Istart=-3/Iend=0/P1=1/I'start =1, the size of the first RBG is 1, and only the RBo is included; in case that Istart=-2/Iend=1/P1=2/I'start=2, the size of the first RBG is 2, and the RB0 and the RB1 are included; in case that Istart=-1/Iend=2/P1=3/I'start =3, the size of the first RBG is 3, and the RB0, the RB1 and the RB2 are included; in case that Istart=0/Iend=3/P1=4/ I'start =4, the size of the first RBG is 4, and the RB0 to the RB3 are included.

[0053] Through the above modes, the RB included in the first RBG may be determined flexibly and accurately.

[0054] In another optional embodiment, the determining the RB included in the first RBG in the BWP includes: determining the RB included in the first RBG in the BWP according to an offset between a first RB in the BWP and a first RB of a carrier bandwidth.

[0055] The above offset may be understood as the quantity of RBs by which the first RB in the BWP are spaced from the first RB of the carrier bandwidth. For example, in case that the RBs of the BWP of the user equipment are numbered from RB0 in ascending order of frequency, the first RB (RB0) in the BWP has an index of RBS in the carrier bandwidth, and the index of the first RB of the carrier bandwidth is RB0, then the offset is S as shown in Fig.7.

[0056] It should be noted that both the first RB in the BWP and the first RB of the carrier bandwidth refer to the first RBs on a same side. For example, the first RB in the BWP and the first RB of the carrier bandwidth are the first RB on the low frequency side of the BWP and the first RB on the low frequency side of the carrier bandwidth respectively, or the first RB on the high frequency side of the BWP and the first RB on the high frequency side of the carrier bandwidth respectively.

[0057] In this implementation, it may be achieved that each user equipment determines the RB included in the first RBG in the BWP according to the user equipment's own offset. In practice, the RBG sizes of user equipment are generally in a multiple relationship, for example: the RBG sizes are respectively equal to 1, 2, 4, 8 and 16, etc. In this way, as shown in Fig.5, the RBG partitioning of overlapping BWPs are matched, so as to improve resource utilization efficiency.

[0058] Optionally, the determining the RB included in the first RBG in the BWP according to the offset between the first RB in the BWP and the first RB of the carrier bandwidth includes:
determining a quantity T of RBs in the BWP as the RB included in the first RBG, wherein the T is equal to P-(S mod P), the P is the RBG size, the S is the offset, and the mod is a remainder function.

[0059] It may be realized that the quantity of RBs included in the first RBG is T. Of course, it should be noted that, because BWPs of different user equipment are different, different user equipment may have different T. For example, assuming that user equipment has P = 8 and S = 106, the size of the first RBG is 8-106% 8 = 6, wherein the 106% 8 means 106 modulo 8, then in Fig.7, RBG#0 includes RBs to RBS+5.

[0060] Since the T is equal to P-S mod P, and in practice, the P of user equipment are generally in a multiple relationship, boundaries of the RBGs partitioned by various user equipment may be aligned. For example, P of user equipment 3 is twice as much as P of user equipment 1 and user equipment 2, and T of the user equipment 1 and the user equipment 3 are respectively equal to their P, that is, S mod P is equal to 0, and T of the user equipment 2 is less than P of the user equipment 2. Through the above steps, the RBG partitioning as shown in Fig.5 may be achieved. Boundaries of RBG#0 to RBG#5 of the user equipment 1 and boundaries of RBG#0 to RBG#2 of the user equipment 3 are aligned, and boundaries of RBG#1 to RBG#5 of the user equipment 2 and boundaries of RBG#3 to RBG#5 of the user equipment 3 are aligned, wherein P of the user equipment 3 is twice as much as P of the user equipment 1 and P of the user equipment 2.

[0061] Optionally, the determining the quantity T of RBs in the BWP as the RB included in the first RBG includes: taking a quantity T of RBs starting from the first RB in the BWP as the RB included in the first RBG.
