Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a method, apparatus and readable storage medium for transmitting configured grant-downlink feedback information (CG-DFI). Background Technology

[0002] In the new radio (NR) frequency band from 52.6 GHz to 71 GHz, subcarrier spacing will be either 480 kHz or 960 kHz. The 480 kHz subcarrier spacing corresponds to a time slot duration of 1 / 32 millisecond (ms), while the 960 kHz subcarrier spacing corresponds to a time slot duration of 1 / 64 ms. With shorter time slot durations, the processing time of one physical downlink shared channel (PDSCH) will correspond to multiple consecutive time slots, and the round trip time (RTT) will correspond to even more time slots; for example, one RTT might correspond to 64 time slots. In this scenario, more parallel hybrid automatic repeat request (HARQ) processes need to be supported.

[0003] The 52.6 GHz to 71 GHz frequency band also includes unlicensed frequency bands that can be used for communication. In the unlicensed frequency bands, in order to enable user equipment (UE) to know the feedback on the uplink data after it is transmitted, configured grant-downlink feedback information (CG-DFI) is introduced.

[0004] As the subcarrier spacing increases and the maximum number of uplink HARQ processes increases, how to provide feedback for a large number of uplink HARQ processes is a problem that needs to be solved. Summary of the Invention

The user equipment 101 is configured to support carrier aggregation and can be connected to multiple carrier units of the network device 102, including a primary carrier unit and one or more secondary carrier units.

[0064] It should be understood that the wireless communication system 100 described above is applicable to both low-frequency and high-frequency scenarios.

These network devices include, but are not limited to, the network device 102 shown in the figure.

[0066] User equipment 101 may be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal device in a future 5G network or terminal device in a future evolved PLMN network, etc.

[0067] Network device 102 can be an access network device (or access point). Access network device refers to equipment that provides network access functionality, such as a radio access network (RAN) base station. Specifically, network device 102 may include a base station (BS), or a base station and radio resource management equipment used to control the base station. Network device 102 may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations.

[0069] This disclosure provides a method for transmitting CG-DFI. (Refer to...) Figure 2 , Figure 2 This is a flowchart illustrating a method for transmitting CG-DFI according to an exemplary embodiment, such as... Figure 2 As shown, this method includes:

[0070] In step S21, network device 102 determines the composition mode of CG-DFI, wherein the maximum number of uplink HARQ processes corresponding to the composition mode is greater than 16.

[0071] In step S21, network device 102 sends a CG-DFI conforming to the composition method to user equipment 101.

[0072] Step S23, User equipment 101 receives CG-DFI conforming to the composition method from network device 102.

[0073] In some possible embodiments, CG-DFI is activated only after the CG-PUSCH transmission function is configured.

[0074] Transmitting CG-DFI can achieve the following two functions:

[0075] First, network device 102 promptly provides user equipment 101 with HARQ-ACK information for CG-PUSCH so that user equipment 101 can adjust the size of the contention window in the next transmission.

[0076] Second, user equipment 101 can determine whether to retransmit CG-PUSCH or terminate CG-PUSCH transmission in advance based on HARQ-ACK information.

[0077] In some possible embodiments, CG-DFI is transmitted using downlink control information (DCI) in the format of 0-1, i.e., DCI0-1, and scrambled using a configured scheduled-radio network temporary identifier (CS-RNTI).

[0078] When user equipment 101 communicates on an unlicensed frequency band, if it is configured to detect DCI 0-1 and the CG-PUSCH transmission function is activated, user equipment 101 will detect CG-DFI.

[0079] This disclosure provides a method for transmitting CG-DFI, which is performed by a network device 102, and includes:

[0080] The composition of CG-DFI is determined, wherein the maximum number of uplink HARQ processes corresponding to the composition is greater than 16;

[0081] Send a CG-DFI conforming to the composition to the user equipment.

[0082] In one possible embodiment, the CG-DFI includes multiple HARQ-ACK messages.

[0083] In HARQ-ACK transmission based on transport blocks (TBs), one TB corresponds to one HARQ-ACK bit, and thus one HARQ-ACK message corresponds to one HARQ-ACK bit. For example, CG-DFI consists of 16 bits, each bit representing one HARQ-ACK message.

[0084] In HARQ-ACK transmission based on code block groups (CBGs), a block size (TB) comprises multiple CBGs, and one HARQ-ACK message corresponds to the HARQ-ACK message of one TB. Each CBG corresponds to one HARQ-ACK bit, thus one HARQ-ACK message corresponds to multiple HARQ-ACK bits. For example, CG-DFI comprises 16 bits, with each 2 bits representing one HARQ-ACK message.

[0085] In this embodiment of the disclosure, for cases where the maximum number of uplink HARQ processes is greater than 16, a corresponding CG-DFI composition method is set, a CG-DFI conforming to the composition method is constructed according to the composition method, and a CG-DFI conforming to the composition method is sent to the user equipment 101. Thus, in application scenarios where the maximum number of uplink HARQ processes is greater than 16, the CG-DFI conforming to the composition method reflects the HARQ-ACK information of all or part of the uplink HARQ processes in all uplink HARQ processes corresponding to the maximum number of uplink HARQ processes.

[0086] This disclosure provides a method for transmitting CG-DFI, which is performed by a network device 102, and includes:

[0087] The composition of CG-DFI is determined, wherein the maximum number of uplink HARQ processes corresponding to the composition is greater than 16;

[0088] Send a CG-DFI conforming to the composition scheme to the user equipment, wherein the HARQ-ACK information in the CG-DFI conforming to the composition scheme corresponds to all or part of the uplink HARQ processes in all uplink HARQ processes of the maximum number of uplink HARQ processes.

[0089] In this embodiment of the disclosure, for cases where the maximum number of uplink HARQ processes is greater than 16, a corresponding CG-DFI composition method is set, a CG-DFI conforming to the composition method is constructed according to the composition method, and a CG-DFI conforming to the composition method is sent to the user equipment 101. Thus, in application scenarios where the maximum number of uplink HARQ processes is greater than 16, the CG-DFI conforming to the composition method reflects the HARQ-ACK information of all or part of the uplink HARQ processes in all uplink HARQ processes corresponding to the maximum number of uplink HARQ processes.

[0092] Send a CG-DFI conforming to the composition to the user equipment.

[0093] In this embodiment of the disclosure, first indication information for indicating the composition of CG-DFI is sent via radio link layer signaling, so that user equipment 101 can clearly know the composition of CG-DFI and thus accurately parse CG-DFI.

[0094] This disclosure provides a method for transmitting CG-DFI, which is performed by a network device 102, and includes:

[0095] The configuration of the CG-DFI as agreed in the protocol is determined; wherein the maximum number of uplink HARQ processes corresponding to the configuration is greater than 16.

[0096] Send a CG-DFI conforming to the composition to the user equipment.

[0097] In this embodiment of the disclosure, the composition of CG-DFI is agreed upon by the protocol, and both network device 102 and user equipment 101 can determine the composition of CG-DFI unilaterally according to the protocol.

[0098] This disclosure provides a method for transmitting CG-DFI, which is performed by a network device 102, and includes:

[0100] Send a CG-DFI conforming to the composition to the user equipment.

[0101] In this embodiment of the disclosure, by expanding the capacity of the CG-DFI, the CG-DFI carries the HARQ-ACK information of all uplink HARQ processes. Thus, when the maximum number of uplink HARQ processes is greater than 16, the HARQ-ACK information of all uplink HARQ processes is sent to the user equipment, so that the user equipment 101 can know the HARQ-ACK information of all uplink HARQ processes.

[0102] In a possible specific example, the maximum number of uplink HARQ processes is 32. The CG-DFI consists of 32 bits, with each bit corresponding to the HARQ-ACK information of one uplink HARQ process. Thus, the CG-DFI can represent the HARQ-ACK information of all uplink HARQ processes.

[0103] In a possible specific example, the maximum number of uplink HARQ processes is 64. The CG-DFI consists of 64 bits, with each bit corresponding to the HARQ-ACK information of one uplink HARQ process. Thus, the CG-DFI can represent the HARQ-ACK information of all uplink HARQ processes.

[0104] In a possible specific example, the maximum number of uplink HARQ processes is 128. The CG-DFI consists of 128 bits, with each bit corresponding to the HARQ-ACK information of one uplink HARQ process. Thus, the CG-DFI can represent the HARQ-ACK information of all uplink HARQ processes.

[0105] In a possible specific example, the maximum number of uplink HARQ processes is 256. The CG-DFI consists of 256 bits, with each bit corresponding to the HARQ-ACK information of one uplink HARQ process. Thus, the CG-DFI can represent the HARQ-ACK information of all uplink HARQ processes.

[0106] This disclosure provides a method for transmitting CG-DFI, which is performed by a network device 102, and includes:

[0107] The composition mode of the CG-DFI is determined, wherein the maximum number of uplink HARQ processes corresponding to the composition mode is greater than 16; the composition mode corresponds to the second mode, wherein the number of HARQ-ACK messages contained in the CG-DFI in the second mode is greater than the maximum number of uplink HARQ processes.

[0109] In this embodiment of the disclosure, by expanding the capacity of the CG-DFI, the CG-DFI carries the HARQ-ACK information of all uplink HARQ processes. Thus, when the maximum number of uplink HARQ processes is greater than 16, the HARQ-ACK information of all uplink HARQ processes is sent to the user equipment, so that the user equipment 101 can know the HARQ-ACK information of all uplink HARQ processes.

[0110] In a possible specific example, the maximum number of uplink HARQ processes is 32. The CG-DFI consists of 64 bits, with each of the first 32 bits corresponding to the HARQ-ACK information of one uplink HARQ process. Thus, the CG-DFI can represent the HARQ-ACK information of all uplink HARQ processes.

[0111] In a possible specific example, the maximum number of uplink HARQ processes is 64. The CG-DFI consists of 128 bits, with each of the first 64 bits corresponding to the HARQ-ACK information of one uplink HARQ process. Thus, the CG-DFI can represent the HARQ-ACK information of all uplink HARQ processes.

[0112] In a possible specific example, the maximum number of uplink HARQ processes is 128. The CG-DFI consists of 256 bits, with each of the first 128 bits corresponding to the HARQ-ACK information of one uplink HARQ process. Thus, the CG-DFI can represent the HARQ-ACK information of all uplink HARQ processes.

[0113] This disclosure provides a method for transmitting CG-DFI, which is performed by a network device 102, and includes:

[0114] The composition mode of the CG-DFI is determined, wherein the maximum number of uplink HARQ processes corresponding to the composition mode is greater than 16; the composition mode corresponds to the third mode, wherein the number of hybrid automatic repeat request feedback HARQ-ACK messages contained in the CG-DFI in the third mode is less than the maximum number of uplink HARQ processes, each hybrid automatic repeat request feedback HARQ-ACK message contained in the CG-DFI corresponds to a logical value, and the logical value corresponds to the result of logical operation of HARQ-ACK messages of more than one uplink HARQ process.

[0115] Send a CG-DFI conforming to the composition to the user equipment.

[0116] In this embodiment of the disclosure, the HARQ-ACK information of one or more uplink HARQ processes is compressed into a single logical value after logical operations, so that this single logical value represents the HARQ-ACK information of the one or more uplink HARQ processes. Thus, even when the number of HARQ-ACK information fed back by the Hybrid Automatic Repeat Request in the CG-DFI is less than the maximum number of uplink HARQ processes, it can still reflect the HARQ-ACK information of all uplink HARQ processes corresponding to the maximum number of uplink HARQ processes.
