Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and particularly to a method, apparatus, and readable storage medium for transmitting configured grant-downlink feedback information (CG-DFI).

Background Art

[0002] In the frequency band of 52.6 gigahertz (GHz) to 71 GHz of new radio (NR), a subcarrier spacing of 480 kilohertz (KHz) or 960 KHz is used. Here, the time length of a slot corresponding to a subcarrier spacing of 480 KHz is 1 / 32 millisecond (ms), and the time length of a slot corresponding to a subcarrier spacing of 960 KHz is 1 / 64 ms. With a short slot time length, the processing time length of one physical downlink shared channel (PDSCH) corresponds to a plurality of consecutive slots, and the time length of the round trip time (RTT) of a message corresponds to more slots. For example, one RTT time length corresponds to 64 slots. In this case, it is necessary to support more parallel hybrid automatic repeat request (HARQ) processes.

[0003] In the frequency band of 52.6 GHz to 71 GHz, an unlicensed frequency for communication may be included. In the unlicensed frequency band, configured grant-downlink feedback information (CG-DFI) is introduced to enable a user equipment (UE) to obtain feedback regarding the uplink data after transmitting the uplink data.

[0004] As subcarrier spacing increases and the maximum number of uplink HARQ processes increases, how to provide feedback to a large number of uplink HARQ processes becomes a problem that needs to be addressed. [Overview of the Initiative] [Problems that the invention aims to solve]

The user equipment 101 may have wireless transmission and reception functions and may communicate (e.g., wirelessly) with one or more network devices of one or more communication systems and may accept network services provided by the network devices, the network devices here include, but are not limited to, the network device 102 shown in the drawings.

[0053] The network device 102 may also be an access network device (also called an access network site). Here, an access network device refers to a device that provides network access functions, such as a radio access network (RAN) base station. Specifically, the network device 102 may include a base station (BS), or a base station and a radio resource management device for controlling the base station. The network device 102 may further include relay stations (relay devices), access points, and base stations in future 5G networks, base stations or NR base stations in future advanced PLMN networks, etc. The network device 102 may also be a wearable device or an in-vehicle device.

[0055] The embodiments of this disclosure provide a method for transmitting CG-DFI. Referring to Figure 2, Figure 2 is a flowchart of a CG-DFI transmission method shown in an exemplary embodiment, and as shown in Figure 2, this method includes the following steps S21 to S23.

[0056] In step S21, the network device 102 determines the CG-DFI configuration scheme, and the maximum number of uplink HARQ processes corresponding to the said configuration scheme is greater than 16.

[0057] In step S22, the network device 102 transmits a CG-DFI that conforms to the above configuration to the user device 101.

[0058] In step S23, the user device 101 receives a CG-DFI that conforms to the above configuration from the network device 102.

[0059] In some possible embodiments, CG-DFI is activated after the CG-PUSCH transmission function is configured.

[0060] CG-DFI transmission can achieve the following two effects: 1. The network device 102 provides CG-PUSCH HARQ-ACK information in a timely manner so that the user device 101 can adjust the size of the competition window in the next transmission. 2. The user device 101 can determine, based on the HARQ-ACK information, whether to retransmit the CG-PUSCH or to terminate the transmission of the CG-PUSCH early.

[0061] In some possible embodiments, CG-DFI is transmitted using downlink control information (DCI) with a format of 0-1, i.e., DCI0-1, and scrambled using a configured scheduled-radio network temporary identifier (CS-RNTI).

[0062] When user device 101 communicates on an unlicensed frequency, and DCI 0-1 detection is enabled and the CG-PUSCH transmission function is activated, user device 101 detects CG-DFI.

[0063] Embodiments of the present disclosure provide a method for transmitting a CG-DFI, the method being performed by a network device 102, the method comprising the steps of determining a configuration scheme for the CG-DFI, wherein the maximum number of uplink HARQ processes corresponding to the configuration scheme is greater than 16, and transmitting a CG-DFI conforming to the configuration scheme to the user device.

[0064] In one possible embodiment, the CG-DFI includes multiple HARQ-ACK pieces of information.

[0065] In HARQ-ACK transmission based on transport blocks (TBs), one TB corresponds to one HARQ-ACK bit, and one HARQ-ACK piece of information corresponds to one HARQ-ACK bit. For example, CG-DFI contains 16 bits, each bit representing one HARQ-ACK piece of information.

[0066] In HARQ-ACK transmission based on code block groups (CBGs), one TB contains multiple CBGs, one HARQ-ACK piece of information corresponds to the HARQ-ACK piece of information of one TB, and each CGB corresponds to one HARQ-ACK bit, so one HARQ-ACK piece of information corresponds to multiple HARQ-ACK bits. For example, CG-DFI contains 16 bits, each of which 2 bits represents one HARQ-ACK piece of information.

[0067] In the embodiments of this disclosure, a corresponding CG-DFI configuration method is set for cases where the maximum number of uplink HARQ processes is greater than 16, a CG-DFI conforming to the configuration method is constructed based on the configuration method, and the CG-DFI conforming to the configuration method is transmitted to the user device 101. As a result, in application scenes where the maximum number of uplink HARQ processes is greater than 16, the HARQ-ACK information of all or some of the uplink HARQ processes corresponding to the maximum number of uplink HARQ processes is reflected in the CG-DFI conforming to the configuration method.

[0068] Embodiments of the present disclosure provide a method for transmitting a CG-DFI, the method being performed by a network device 102, the method comprising the steps of: determining a configuration scheme for the CG-DFI, the maximum number of uplink HARQ processes corresponding to the configuration scheme being greater than 16; and transmitting a CG-DFI conforming to the configuration scheme to the user device, the HARQ-ACK information in the CG-DFI conforming to the configuration scheme corresponding to all or some of the uplink HARQ processes of the maximum number of uplink HARQ processes.

As a result, in application scenes where the maximum number of uplink HARQ processes is greater than 16, the HARQ-ACK information of all or some of the uplink HARQ processes corresponding to the maximum number of uplink HARQ processes is reflected in the CG-DFI conforming to the configuration method.

[0071] In the embodiments of this disclosure, the CG-DFI is accurately analyzed by transmitting first instruction information to indicate the CG-DFI configuration scheme via wireless link layer signaling, thereby clearly informing the user device 101 of the CG-DFI configuration scheme.

[0072] Embodiments of the present disclosure provide a method for transmitting CG-DFI, which is performed by a network device 102, and the method includes the steps of determining a protocol-defined CG-DFI configuration scheme, wherein the maximum number of uplink HARQ processes corresponding to the configuration scheme is greater than 16, and transmitting a CG-DFI conforming to the configuration scheme to the user device.

[0073] In the embodiments of this disclosure, the CG-DFI configuration method is defined by a protocol, and both the network device 102 and the user device 101 can determine the CG-DFI configuration method unilaterally based on the protocol.

[0074] The present disclosure provides a method for transmitting a CG-DFI according to an embodiment of the present disclosure, the method being performed by a network device 102, the method comprising the steps of determining a configuration scheme for the CG-DFI, wherein the maximum number of uplink HARQ processes corresponding to the configuration scheme is greater than 16, the configuration scheme corresponds to a first scheme, and in the first scheme, the number of HARQ-ACK information included in the CG-DFI is equal to the maximum number of uplink HARQ processes, and transmitting a CG-DFI conforming to the configuration scheme to the user device.

[0075] In the embodiments of this disclosure, the capacity of the CG-DFI is expanded so that the HARQ-ACK information of all uplink HARQ processes is carried to the CG-DFI, thereby, if the maximum number of uplink HARQ processes is greater than 16, the HARQ-ACK information of all uplink HARQ processes is transmitted to the user device, informing the user device 101 of the HARQ-ACK information of all uplink HARQ processes.

[0076] In one possible example, the maximum number of uplink HARQ processes is 32. The CG-DFI contains 32 bits, each bit corresponding to the HARQ-ACK information of one uplink HARQ process. This allows the CG-DFI to reflect the HARQ-ACK information of all uplink HARQ processes.

[0077] In one possible example, the maximum number of uplink HARQ processes is 64. The CG-DFI contains 64 bits, each bit corresponding to the HARQ-ACK information of one uplink HARQ process. This allows the CG-DFI to reflect the HARQ-ACK information of all uplink HARQ processes.

[0078] In one possible example, the maximum number of uplink HARQ processes is 128. The CG-DFI contains 128 bits, each bit corresponding to the HARQ-ACK information of one uplink HARQ process. This allows the CG-DFI to reflect the HARQ-ACK information of all uplink HARQ processes.

[0079] In one possible example, the maximum number of uplink HARQ processes is 256. The CG-DFI contains 256 bits, each bit corresponding to the HARQ-ACK information of one uplink HARQ process. This allows the CG-DFI to reflect the HARQ-ACK information of all uplink HARQ processes.

[0080] Embodiments of the present disclosure provide a method for transmitting CG-DFI, which is performed by a network device 102, and the method includes the steps of determining a configuration scheme for CG-DFI, wherein the maximum number of uplink HARQ processes corresponding to the configuration scheme is greater than 16, the configuration scheme corresponds to a second scheme, and in the second scheme, the number of HARQ-ACK information included in the CG-DFI is greater than the maximum number of uplink HARQ processes, and transmitting a CG-DFI conforming to the configuration scheme to the user device.

[0081] In the embodiments of this disclosure, the capacity of the CG-DFI is expanded so that the HARQ-ACK information of all uplink HARQ processes is carried to the CG-DFI, thereby, if the number of uplink HARQ processes is greater than 16, the HARQ-ACK information of all uplink HARQ processes is transmitted to the user device, informing the user device 101 of the HARQ-ACK information of all uplink HARQ processes.

[0082] In one possible example, the maximum number of uplink HARQ processes is 32. The CG-DFI contains 64 bits, and of the first 32 bits, each bit corresponds to the HARQ-ACK information of one uplink HARQ process. This allows the CG-DFI to reflect the HARQ-ACK information of all uplink HARQ processes.

[0083] In one possible example, the maximum number of uplink HARQ processes is 64. The CG-DFI contains 128 bits, and of the first 64 bits, each bit corresponds to the HARQ-ACK information of one uplink HARQ process. This allows the CG-DFI to reflect the HARQ-ACK information of all uplink HARQ processes.

[0084] In one possible example, the maximum number of uplink HARQ processes is 128. The CG-DFI contains 256 bits, and of the first 128 bits, each bit corresponds to the HARQ-ACK information of one uplink HARQ process. This allows the CG-DFI to reflect the HARQ-ACK information of all uplink HARQ processes.

[0085] Embodiments of the present disclosure provide a method for transmitting a CG-DFI, which is performed by a network device 102, and the method includes the steps of determining a configuration scheme for the CG-DFI, wherein the maximum number of uplink HARQ processes corresponding to the configuration scheme is greater than 16, the configuration scheme corresponds to a third scheme, in the third scheme, the number of hybrid automatic retransmission request feedback (HARQ-ACK) information entries included in the CG-DFI is less than the maximum number of uplink HARQ processes, each hybrid automatic retransmission request feedback (HARQ-ACK) information entry included in the CG-DFI corresponds to a single logical value, the logical value corresponds to the result of a logical operation on HARQ-ACK information of one or more uplink HARQ processes, and transmitting a CG-DFI conforming to the configuration scheme to the user device.

[0086] In the embodiments of this disclosure, the HARQ-ACK information of one or more uplink HARQ processes is compressed into a single logical value after performing a logical operation on the HARQ-ACK information of one or more uplink HARQ processes, thereby representing the HARQ-ACK information of one or more uplink HARQ processes with a single logical value. This makes it possible to reflect the HARQ-ACK information of all uplink HARQ processes corresponding to the maximum number of uplink HARQ processes, even when the number of hybrid automatic retransmission request feedback (HARQ-ACK) information entries included in the CG-DFI is less than the maximum number of uplink HARQ processes.
