Description

Technical Field



[0001] Implementations of the present disclosure relate to the communication field, and more particularly, to a data transmission method, a network device and a terminal device.

Background



[0002] In an existing Long Term Evolution (LTE) system, a broadcast mechanism is used for system information. Specifically, after user equipment (UE) acquires a downlink synchronization signal from a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS), the UE monitors Master Information Block (MIB) and System Information Block Type 1 (SIB1) information on specific time-frequency resources, and then acquires first scheduling information of another SIB from the SIB1. In other words, main system information (MSI) and other system information (other SI) are not distinguished in system information of the LTE, and a unified and fixed scheduling mode is adopted.

[0003] However, this mechanism cannot support broadcasting system information flexibly according to needs. The UE needs to acquire unnecessary system information, which occupies too much downlink broadcast resources.

[0004] In addition, a 5th Generation (5G) New Radio (NR) system also urgently needs a mechanism for broadcasting system information according to needs to be proposed.

Detailed Description



[0040] FIG. 1 is a schematic diagram of an application scenario according to an implementation of the present disclosure.

[0041] As shown in FIG. 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0042] It should be understood that the communication system 100 is only an example for describing the implementation of the present disclosure. However, implementations of the present disclosure are not limited to this. In other words, the technical solutions in the implementations of the present disclosure may be applied in various communication systems, for example, a Long Term Evolution (LTE) system, an LTE Time Division Duplex (TDD) system, a Universal Mobile Telecommunication System (UMTS). For ease of description, a 5th Generation (5G) New Radio (NR) communication system is used as an example for describing the following implementations of the present disclosure.

[0043] The present disclosure describes various implementations in connection with a network device and a terminal device.

[0044] The network device 120 may refer to any entity on a network side for sending or receiving signals. For example, it may be a user equipment of machine type communication (MTC), an Evolutional Node B (eNB or eNodeB) in LTE, a base station device in a 5G network, or the like.

[0045] In addition, the terminal device 110 may be any terminal device. Specifically, the terminal device 110 may communicate with one or more core networks through a radio access network (RAN), and may also be referred to as an access terminal, a User Equipment (UE), a subscriber unit, a subscriber station, a mobile station, a rover station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. For example, the terminal device may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a wireless communication function, a computing device, or another processing device connected to a wireless modem, an on-board device, a wearable device, a terminal device in a 5G network or the like.

[0046] In an existing LTE system, a broadcast mechanism is used for system information. Specifically, after a terminal device acquires a downlink synchronization signal from a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS), the terminal monitors MIB and SIB1 information on specific time-frequency resources, and then acquires scheduling information of another SIB from SIB1. That is, a unified and fixed scheduling mode is adopted for the system information of the LTE. In other words, the network device cannot support flexibly broadcasting system information. The terminal device may need to acquire unnecessary system information, which occupies too much downlink broadcast resources, and reduces user experience.

[0047] Therefore, an implementation of the present disclosure provides a method for scheduling and indicating system information in a communication system, which allows to perform scheduling and transmission on an MIB, SIB1, and SIB2 in different periods.

[0048] FIG. 2 is a schematic flowchart of a data transmission method according to an implementation of the present disclosure.

[0049] As shown in FIG. 2, the method includes following acts 210, 220, 230.

[0050] In 210, a network device sends first indication information to a terminal device.

[0051] In 220, the network device sends first scheduling information to the terminal device on a Physical Downlink Control Channel (PDCCH) according to the first indication information during a first period.

[0052] In 230, the network device sends a second information block to the terminal device on a PDSCH according to the first scheduling information during the first period.

[0053] Specifically, the network device sends the first indication information to the terminal device. The first indication information is carried in at least one first information block, a plurality of first information blocks sent by the network device to the terminal device on the physical broadcast channel (PBCH) during a first period, include the above at least one first information block. The first indication information is used for indicating a resource position of the first scheduling information on the physical downlink control channel (PDCCH), the first scheduling information is used for indicating a resource position of the second information block on the physical downlink shared channel (PDSCH), and the first period is a period during which the network device sends the second information block to the terminal device on the PDSCH. The network device sends the first scheduling information to the terminal device on the PDCCH according to the first indication information during the first period. The network device sends the second information block to the terminal device on the PDSCH according to the first scheduling information during the first period.

[0054] In other words, the network device sends the plurality of first information blocks to the terminal device, at least one first information block of the plurality of first information blocks includes the first indication information of the first scheduling information located on the PDCCH. The first indication information indicates a resource position of the first scheduling information on the PDCCH, and the first scheduling information indicates a resource position of the second information block on the PDSCH.

[0055] In short, the first indication information sent by the network device to the terminal device, is carried in the at least one information block of the plurality of first information blocks sent by the network device to the terminal device. The first indication information is used for indicating the resource position of the second information block on the PDSCH through the first scheduling information.

[0056] Therefore, after receiving the first indication information, the terminal device may receive the first scheduling information according to the first indication information, and then receive the second information block based on the first scheduling information. In other words, the network device can realize flexible scheduling of the MIB and SIB1 of the network device through different modes for carrying the first indication information.

[0057] It should be noted that the terms "first information block", "second information block", "third information block" and the like are used in embodiments of the present disclosure, but these information blocks should not be limited to these terms. These terms are only used to distinguish information blocks from each other. Similar terms also include scheduling information, indication information, and so on.

[0058] For example, in implementations of the present disclosure, minimum system information (Minimum SI) may be divided into two parts, one part is transmitted in a Physical Broadcast Channel (PBCH), and contents of the information belongs to NR-"Master Information Block (MIB)". The other part is transmitted in a Physical Downlink Shared Channel (PDSCH), which belongs to NR-"System Information Block (SIB)", and also can be called as Remaining System Information (RMSI). Specifically, the RMSI may include an SIB1 and/or SIB2.

[0059] As an example but not limitation, the first information block may refer to an MIB, the second information block may refer to an SIB1, and the third information block may refer to an SIB2.

[0060] It can be seen that a unified and fixed scheduling mode is used for the system information in the LTE. That is, the terminal monitors the MIB and SIB1 on specific time-frequency resources, and then acquires scheduling information of another SIB from the SIB1. In the implementation of the present disclosure, the network device sends system information by using a flexible scheduling mode. In other words, the MIB and SIB1 in the LTE are coupled together by using a unified scheduling mode, while in the implementation of the present disclosure, the scheduling mode of the MIB and SIB1 is decoupled, that is, the MIB and SIB1 are flexibly scheduled.

[0061] The following is an exemplary description of a specific carrying mode of the first indication information in the implementation of the present disclosure.

[0062] In an implementation, a network device sends a plurality of first information blocks to the terminal device during a period of a second information block, and at least one first information block of the plurality of first information blocks is only used for carrying indication information used for indicating scheduling information of the second information block.

[0063] Optionally, each first information block of the plurality of first information blocks is only used for carrying first indication information used for indicating first scheduling information of the second information block.

[0064] Specifically, the network device may send the plurality of first information blocks to the terminal device on the PBCH during the first period, and each first information block of the plurality of first information blocks includes the same first indication information. The first period is a period during which the network device sends the second information block to the terminal device on the PDSCH.

[0065] In addition, an implementation of the present disclosure introduces a concept of a resource control set (CORESET), and the PDCCH is transmitted in the CORESET. The CORESET may occupy 1 to 3 time domain symbols in time domain, and occupy a configurable bandwidth instead of an entire system bandwidth in frequency domain. In other words, the frequency resource bandwidth occupied by the CORSET and the number of time domain symbols may be configured by the network device for the terminal device through a high-layer signaling. In other words, a search space of each terminal device may be defined based on a resource control set (CORESET).

[0066] That is, the first indication information in the implementation of the present disclosure may be a CORESET value.

[0067] It can be understood that in an implementation of the present disclosure, the network device may set different CORESET values for the PBCH during different first periods, and set a same CORESET value for the PBCH during a single first period, so that each first information block of the plurality of first information blocks during each first period, includes the same first indication information.

[0068] For example, as shown in FIG. 3, assuming that a period of an NR-MIB is 10ms, a period of an NR-SIB1 is 40ms, scheduling resources of RMSI in a PDSCH, which are indicated in every 4 NR-MIBs in a PBCH, may be set to a same value.

[0069] Therefore, the existing PBCH and PDCCH formats can be unchanged, and the application range of the data transmission method of the implementation of the invention can be further improved.

[0070] Optionally, only one first information block of the plurality of first information blocks is used for carrying the first indication information used for indicating the first scheduling information of the second information block.

[0071] Specifically, before the network device sends the first indication information to the terminal device, the network device may determine a first system frame number during the first period. The network device sends the plurality of first information blocks to the terminal device on the PBCH during the first period, and a first information block, of the plurality of first information blocks, corresponding to the first system frame number includes the first indication information.

[0072] More particularly, the network device may set different CORESET values for PBCHs during different first periods, and different CORESET values may be set for a PBCH during one single first period, so that only one first information block of the plurality of first information blocks includes the first indication information during one single first period.

[0073] For example, the first period is a multiple of a second period, and the second period is a period during which the network device sends the plurality of first information blocks to the terminal device on the PBCH. For example, the network device may determine the first system frame number according to following criteria: a remainder of the first system frame number divided by a first value is equal to a first threshold, the first value is a quotient of the first period divided by the second period, and the first threshold is used for the network device to determine the first system frame number in the first period.

[0074] For example, as shown in FIG. 4, assuming that a period of an NR-MIB is 10ms, a period of an NR-SIB1 is 40ms, that is, during 40ms, only one NR-MIB in every 4 NR-MIBs carries first indication information used for indicating a transmission resource of an SIB1.

[0075] Further, how to carry it may be determined based on a first threshold in the implementation of the present disclosure. For example, system frame number (SFN) mod 4 = 0, or 1, or 2, or 3. In this way, the terminal device only needs to read the CORESET on the PDCCH according to the first threshold after receiving the NR-MIB, and then acquires anSIBl on the PDSCH.

[0076] It should be understood that in the implementations of the present disclosure, FIG. 3 and FIG.4 only illustrate the implementations of the network device flexibly indicating the NR-MIB and the SIB1 for the terminal device when the first information block is the NR-MIB and the second information block is the SIB1. Scheduling modes of other system information are not specifically limited in the implementation of the present disclosure.

[0077] For example, the second information block may further includes second scheduling information, the second scheduling information is used for indicating a resource position of a third information block on a PDSCH, and the second information block and the third information block are different information blocks. Further, the third information block may be an SIB2. Specifically, the network device may put the SIB2 into a scheduling info list included in an SIB1.

[0078] In another implementation, a network device may send a plurality of first information blocks to a terminal device during a period of a second information block. The plurality of first information blocks may carry first indication information used for indicating first scheduling information of the second information block, and the second indication information used for indicating second scheduling information of a third information block.

[0079] However, since the CORESET of the PDCCH can only indicate one type of an SIB, i.e. an SIB1 or an SIB2, the assumption here is that RMSI includes an SIB1 and an SIB2.

[0080] Optionally, different first information blocks of the plurality of first information blocks carry the first indication information and the second indication information.

[0081] Specifically, before the network device sends the first indication information to the terminal device, the network device may determine a first system frame number and a second system frame number during the first period. The first system frame number and the second system frame number are different system frame numbers. The network device sends second indication information to the terminal device according to the first system frame number and the second system frame number. The first indication information is carried in a first information block, of the plurality of first information blocks, corresponding to the first system frame number. The second indication information is carried in a first information block, of the plurality of first information blocks, corresponding to the second system frame number in the first information block. The second indication information is used for indicating a resource position of second scheduling information on the PDCCH. The second scheduling information is used for indicating a resource position of a third information block on a PDSCH. The third information block and the second information block are different information blocks.

[0082] For example, the first period may be a multiple of a second period, and the second period is a period during which the network device sends the plurality of first information blocks to the terminal device on the PBCH. Specifically, the terminal device may determine the first system frame number and the second system frame number according to following criteria: a remainder of the first system frame number divided by a second value is equal to a second threshold, the second threshold is used for the network device to determine the first system frame number during the first period; a remainder of the second system frame number divided by the second value is equal to a third threshold, the third threshold is used for the network device to determine the second system frame number during the first period, and the second threshold and the third threshold are not equal.

[0083] Further, the first threshold is equal to 0, and the second threshold is equal to 1.

[0084] For example, as shown in FIG. 5, assuming that a period of an NR-MIB is 10ms, a period of an NR-SIB1 is 40ms, that is, during 40ms, only one NR-MIB in every 4 NR-MIBs carries first indication information used for indicating a transmission resource of an SIB1, and only one NR-MIB in every 4 NR-MIBs carries second indication information used for indicating a transmission resource of an SIB2. The NR-MIB carrying the first indication information and the NR-MIB carrying the second indication information are different NR-MIBs.

[0085] Further, how to carry it may be determined based on the second threshold and the third threshold in the implementation of the present disclosure. For example, when SFN mod 2=0, a PDCCH CORESET indicates an SIB1, when SFN mod 2=1, the PDCCH CORESET indicates an SIB2.

[0086] It should be noted that the various numerical values, the SIB1 and the SIB2 of the implementation of the present disclosure are merely exemplary descriptions, and the implementation of the present disclosure is not limited thereto. The core idea of the implementation of the invention is to enable the terminal device to acquire different remaining system information at different NB-MIB periods.

[0087] It should also be understood that the first threshold, the second threshold and the third threshold in the implementation of the present disclosure may be configured by the network device or may be determined through negotiation with the network device, and the implementation of the present disclosure is not specifically to limit this.
