[0079] See also Figure 2 , is a flow chart of a communication method provided in an embodiment of the present application. Figure 2 As shown, the communication method may include but is not limited to the following steps. In the embodiment of the present application, S represents a step.

[0080] S201: The network device sends first indication information, where the first indication information indicates that downlink control information (DCI) includes second indication information for indicating activation or deactivation of HARQ feedback. Correspondingly, the terminal device receives the first indication information.

[0081] The HARQ feedback includes HARQ-acknowledgement (ACK) and / or HARQ-negative acknowledgement (NACK). Deactivating the HARQ feedback may include deactivating HARQ-ACK and / or deactivating HARQ-NACK, and activating the HARQ feedback may include activating HARQ-ACK and / or activating HARQ-NACK.

[0082] Deactivating HARQ-ACK may refer to not using the HARQ-ACK feedback mechanism at the physical layer of both the network device and the terminal device. Not using the HARQ-ACK feedback mechanism at the physical layer of the terminal device may include at least one of the following: the terminal device does not perform HARQ merging, and the terminal device does not perform HARQ-ACK feedback on the data packet (i.e., does not send HARQ-ACK). Not using the HARQ-ACK feedback mechanism at the physical layer of the network device may include at least one of the following: the network device does not receive HARQ-ACK, and after the network device sends a data packet, it does not wait to receive the HARQ-ACK for the data packet. Similarly, activating HARQ-ACK may refer to using the HARQ-ACK feedback mechanism at the physical layer of both the network device and the terminal device. Using the HARQ-ACK feedback mechanism at the physical layer of the terminal device may include at least one of the following: the terminal device performs HARQ merging, and the terminal device performs HARQ-ACK feedback on the data packet (i.e., sends HARQ-ACK when the data packet is successfully received). Using the HARQ-ACK feedback mechanism at the physical layer of the network device may include at least one of the following: the network device receives the HARQ-ACK, and after the network device sends a data packet, it waits to receive the HARQ-ACK for the data packet.

[0083] Deactivating HARQ-NACK may refer to not using the HARQ-NACK feedback mechanism at the physical layer of both the network device and the terminal device. Not using the HARQ-NACK feedback mechanism at the physical layer of the terminal device may include at least one of the following: the terminal device does not perform HARQ merging, and the terminal device does not perform HARQ-NACK feedback on the data packet (i.e., does not send HARQ-NACK). Not using the HARQ-NACK feedback mechanism at the physical layer of the network device may include at least one of the following: the network device does not receive HARQ-NACK, and the network device does not perform HARQ retransmission on the data packet. Similarly, activating HARQ-NACK may refer to using the HARQ-NACK feedback mechanism at the physical layer of both the network device and the terminal device. Using the HARQ-NACK feedback mechanism at the physical layer of the terminal device may include at least one of the following: the terminal device performs HARQ merging, and the terminal device performs HARQ-NACK feedback on the data packet (i.e., sends HARQ-NACK in the event of a failure to receive a data packet). Adopting the HARQ-NACK feedback mechanism at the physical layer of the network device may include at least one of the following: the network device receives the HARQ-NACK, and the network device performs HARQ retransmission on the data packet.

[0084] Optionally, the first indication information may be a high-layer signaling, such as a radio resource control (Radio Resource Control, RRC) signaling.

[0085] S202: The network device sends DCI, and correspondingly, the terminal device receives the DCI.

[0086] After receiving the first indication information, the terminal device obtains the second indication information in the DCI when receiving the DCI, so as to determine whether to perform HARQ feedback according to the second indication information.

[0087] In an embodiment of the present application, the network indicates activation or deactivation of HARQ feedback through the second indication information carried by the DCI.

[0088] In an embodiment of the present application, the second indication information is used to indicate the activation or deactivation of HARQ feedback, and can also be described as: the second indication information is used to indicate the HARQ feedback status, and the HARQ feedback status can specifically be the HARQ-ACK feedback status of the HARQ process corresponding to the transport block (Transport Block, TB) currently scheduled by the DCI, wherein the HARQ feedback status may include the HARQ-ACK feedback status and / or the HARQ-NACK feedback status, the HARQ-ACK feedback status includes HARQ-ACK feedback activation or HARQ-ACK feedback deactivation, and the HARQ-NACK feedback status includes HARQ-NACK feedback activation or HARQ-NACK feedback deactivation.

[0089] In one possible implementation, the first indication information enables the second indication information in the DCI to indicate activation or deactivation of the HARQ feedback, and the protocol stipulates which bit field in the DCI carries the second indication information. In this way, taking the protocol stipulation that the second indication information is carried by the first bit field in the DCI as an example, when the terminal device receives the first indication information, it can determine whether the HARQ feedback state is activated or deactivated through the first bit field in the DCI in combination with the protocol agreement. In this way, the network device does not need to explicitly indicate in the first indication information which bit field in the DCI the second indication information is carried in, which is conducive to saving indication resources. In another possible implementation, the first indication information may indicate which bit field in the DCI the second indication information is carried in.

[0090] In a possible implementation, the second indication information may indicate activation or deactivation of HARQ feedback through a newly extended bit field in the DCI. In other words, the second indication information is carried by a newly extended bit field in the DCI. Alternatively, the second indication information may indicate activation or deactivation of HARQ feedback through N bits in a HARQ process number indication field, a HARQ-ACK resource indication field, or a repetition number indication field, where N is a positive integer. In other words, the second indication information is carried by N bits in a HARQ process number indication field, a HARQ-ACK resource indication field, or a repetition number indication field. Among them, the N bits may include all or part of the bits in the HARQ process number indication field. Alternatively, the N bits may include all or part of the bits in the HARQ-ACK resource indication field. Alternatively, the N bits may include all or part of the bits in the repetition number indication field. By carrying the second indication information through the HARQ process number indication field, the HARQ-ACK resource indication field or the repetition number indication field, there is no need to expand new bits in the DCI, so that the HARQ feedback can be flexibly and dynamically activated or deactivated without increasing the DCI size.

[0091] S203: Based on the second indication information indicating activation of HARQ feedback, the terminal device sends HARQ feedback; or, based on the second indication information indicating deactivation of HARQ feedback, the terminal device does not send HARQ feedback; wherein the HARQ feedback includes HARQ-ACK and / or HARQ-NACK.

[0092] Based on the second indication information indicating activation of HARQ feedback, the terminal device may adopt a HARQ-ACK feedback mechanism and / or a HARQ-NACK feedback mechanism at the physical layer. Exemplarily, the terminal device may send a HARQ-ACK to the network device when successfully receiving a data packet. In the case where the terminal device fails to receive a data packet, the terminal device may send a HARQ-NACK to the network device. Based on the second indication information indicating deactivation of HARQ feedback, the terminal device may not adopt a HARQ-ACK feedback mechanism and / or not adopt a HARQ-NACK feedback mechanism at the physical layer. Exemplarily, the terminal device may not send a HARQ-ACK when successfully receiving a data packet. In the case where the terminal device fails to receive a data packet, the terminal device may not send a HARQ-NACK.

[0093] S204: The second indication information indicates activation of HARQ feedback, and the network device receives HARQ feedback; or the second indication information indicates deactivation of HARQ feedback, and the network device does not receive HARQ feedback.

[0094] The second indication information indicates activation of HARQ feedback, and the network device may adopt the HARQ-ACK feedback mechanism and / or the HARQ-NACK feedback mechanism at the physical layer. Exemplarily, after the network device sends a data packet, it may wait to receive the HARQ-ACK for the data packet. The network device may perform HARQ retransmission on the data packet. The second indication information indicates deactivation of HARQ feedback, and the network device may not adopt the HARQ-ACK feedback mechanism and / or the HARQ-NACK feedback mechanism at the physical layer. Exemplarily, after the network device sends a data packet, it may not receive the HARQ-ACK for the data packet. The network device may not perform HARQ retransmission on the data packet.

[0095] It should be noted that the embodiment of the present application does not limit the execution order of S203 and S204. S203 may be executed first, or S204 may be executed first, or S203 and S204 may be executed simultaneously.

[0096] In the embodiment of the present application, the network device can flexibly and dynamically indicate the HARQ feedback state through the second indication information carried by the DCI, which can effectively improve the system throughput. When the HARQ feedback state is deactivated, the number of HARQ-ACK and HARQ-NACK can be reduced to save transmission resources.

[0097] In a possible implementation, the specific implementation of the second indication information indicating the HARQ feedback state through N bits is: the value of the N bits is the first value indicating deactivation of HARQ feedback (i.e., the second indication information indicates that the HARQ feedback state is deactivated); or, the value of the N bits is the second value indicating activation of HARQ feedback (i.e., the second indication information indicates that the HARQ feedback state is activated). The value of the N bits can also be referred to as the code point of the N bits, and this method can also be understood as: indicating the HARQ feedback state through a specific code point of the N bits. For example, taking the N bits including 1 bit in the HARQ process number indication field, the HARQ-ACK resource indication field, or the repetition number indication field as an example, when the value of the bit is 1, it is used to indicate activation of HARQ feedback; when the value of the bit is 0, it is used to indicate deactivation of HARQ feedback. Or, when the value of the bit is 1, it is used to indicate deactivation of HARQ feedback; when the value of the bit is 0, it is used to indicate activation of HARQ feedback. For another example, taking N bits including all bits in the HARQ-ACK resource indication field or the repetition number indication field, and N=4 as an example, when the value of the 4 bits is 1111, it is used to indicate activation of HARQ feedback; when the value of the 4 bits is 0000 or other values ​​except 1111, it is used to indicate deactivation of HARQ feedback. Alternatively, when the value of the 4 bits is 1111, it is used to indicate deactivation of HARQ feedback; when the value of the bit is 0000 or other values ​​except 1111, it is used to indicate activation of HARQ feedback.

[0098] Optionally, the N bits, the specific code point, the first value, and the second value can all be agreed upon by the protocol, or can be indicated by the network device, which is not limited in the embodiments of the present application. Optionally, the N bits can be the first N bits in the HARQ process number indication field, the HARQ-ACK resource indication field, or the number of repetitions indication field, or the N bits can be the last N bits in the HARQ process number indication field, the HARQ-ACK resource indication field, or the number of repetitions indication field. Optionally, the first value can be a value in the value range of the N bits, the second value can be another value in the value range of the N bits except the first value, or the second value can include other values ​​in the value range of the N bits except the first value.

[0099] The HARQ-ACK resource indication field is originally used to indicate the HARQ-ACK resource position. In a possible implementation, the HARQ-ACK resource indication field includes N bits and a first bit, that is, some bits (N bits) in the HARQ-ACK resource indication field are used to indicate the HARQ feedback state, and another part of the bits (the first bit) in the HARQ-ACK resource indication field are used to indicate the content originally indicated by the HARQ-ACK resource indication field (i.e., indicating the HARQ-ACK resource position). Since the N bits in the HARQ-ACK resource indication field are used to indicate the HARQ feedback state, the bits originally used to indicate the HARQ-ACK resource position in the HARQ-ACK resource indication field are reduced by N. In the embodiment of the present application, the method of indicating the HARQ-ACK resource position by the first bit is as follows: the HARQ-ACK resource position is the HARQ-ACK resource position indicated by the HARQ-ACK resource position candidate value corresponding to the value of the first bit among the M1 HARQ-ACK resource position candidate values, and M1 is a positive integer. Each value of the first bit corresponds to a HARQ-ACK resource position candidate value, and different values ​​of the first bit correspond to different HARQ-ACK resource position candidate values. A HARQ-ACK resource position candidate value is used to indicate a HARQ-ACK resource position. The number of the first bit can be one or more. When the number of the first bit is a, M1 can be 2^ a , a is a positive integer.

[0100] In a possible implementation, the network device may send a third indication information, and accordingly, the terminal device receives the third indication information, and the third indication information is used to indicate that M1 HARQ-ACK resource location candidate values ​​in the first HARQ-ACK resource location candidate value set are valid. Alternatively, the protocol stipulates that M1 HARQ-ACK resource location candidate values ​​in the first HARQ-ACK resource location candidate value set are valid. The number of HARQ-ACK resource location candidate values ​​in the first HARQ-ACK resource location candidate value set is greater than M1, and optionally, the M1 HARQ-ACK resource location candidate values ​​may be the first M1 HARQ-ACK resource location candidate values ​​in the first HARQ-ACK resource location candidate value set, or the last M1 HARQ-ACK resource location candidate values, or the specified M1 HARQ-ACK resource location candidate values. Optionally, the third indication information may be high-layer signaling, such as RRC signaling.

[0101] In another possible implementation, the network device may send fourth indication information, and correspondingly, the terminal device receives the fourth indication information, and the fourth indication information is used to indicate a second HARQ-ACK resource location candidate value set, and the second HARQ-ACK resource location candidate value set includes M1 HARQ-ACK resource location candidate values. In this way, in addition to the first HARQ-ACK resource location candidate value set, the network additionally configures a HARQ-ACK resource location candidate value set (i.e., the second HARQ-ACK resource location candidate value set), and the terminal device can determine the HARQ-ACK resource location through the HARQ-ACK resource location candidate values ​​in the second HARQ-ACK resource location candidate value set. Optionally, the fourth indication information may be high-layer signaling, such as RRC signaling.

[0102] Optionally, the HARQ-ACK resource position candidate values ​​in the first HARQ-ACK resource position candidate value set and the second HARQ-ACK resource position candidate value set may exist in the form of a table or a list. The embodiment of the present application does not limit the organization form of the HARQ-ACK resource position candidate values ​​in the first HARQ-ACK resource position candidate value set and the second HARQ-ACK resource position candidate value set.

[0103] The repetition count indication field is originally used to indicate the number of repeated transmissions of the physical downlink shared channel (PDSCH) or the number of repeated transmissions of the physical uplink shared channel (PUSCH), the repetition count indication field in the DCI for scheduling PDSCH is originally used to indicate the number of repeated transmissions of PDSCH, and the repetition count indication field in the DCI for scheduling PUSCH is originally used to indicate the number of repeated transmissions of PUSCH. In a possible implementation, the repetition count indication field includes N bits and a second bit, that is, part of the bits (N bits) in the repetition count indication field are used to indicate the HARQ feedback status, and another part of the bits (the second bit) in the repetition count indication field are used to indicate the content originally indicated by the repetition count indication field (i.e., indicating the number of repeated transmissions of PDSCH or the number of repeated transmissions of PUSCH). Since N bits in the repetition indication field are used to indicate the HARQ feedback status, the number of bits originally used to indicate the number of repeated transmissions of PDSCH or the number of repeated transmissions of PUSCH in the repetition indication field is reduced by N. In an embodiment of the present application, the method of indicating the number of repeated transmissions of PDSCH or the number of repeated transmissions of PUSCH by the second bit is as follows: the number of repeated transmissions of PDSCH or the number of repeated transmissions of PUSCH is the number of repeated transmissions indicated by the candidate value of the number of repeated transmissions corresponding to the value of the second bit among the M2 candidate values ​​of the number of repeated transmissions, and M2 is a positive integer. Each value of the second bit corresponds to a candidate value of the number of repeated transmissions, and different values ​​of the second bit correspond to different candidate values ​​of the number of repeated transmissions. A candidate value of the number of repeated transmissions is used to indicate a number of repeated transmissions. The number of second bits may be one or more. When the number of second bits is b, M2 may be 2^ b , b is a positive integer.

[0104] In a possible implementation, the network device may send a third indication message, and correspondingly, the terminal device receives the third indication message, and the third indication message is used to indicate that M2 candidate values ​​for the number of repetition transmissions in the first candidate value set for the number of repetition transmissions are valid. Alternatively, the protocol stipulates that M2 candidate values ​​for the number of repetition transmissions in the first candidate value set for the number of repetition transmissions are valid. The number of candidate values ​​for the number of repetition transmissions in the first candidate value set for the number of repetition transmissions is greater than M2, and optionally, the M2 candidate values ​​for the number of repetition transmissions may be the first M2 candidate values ​​for the number of repetition transmissions in the first candidate value set for the number of repetition transmissions, or the last M2 candidate values ​​for the number of repetition transmissions, or a specified M2 candidate values ​​for the number of repetition transmissions.

[0105] In another possible implementation, the network device may send fourth indication information, and correspondingly, the terminal device receives the fourth indication information, and the fourth indication information is used to indicate a second set of candidate values ​​for the number of repeated transmissions, and the second set of candidate values ​​for the number of repeated transmissions includes M2 candidate values ​​for the number of repeated transmissions. In this way, in addition to the first set of candidate values ​​for the number of repeated transmissions, the network additionally configures a set of candidate values ​​for the number of repeated transmissions (i.e., the second set of candidate values ​​for the number of repeated transmissions), and the terminal device can determine the number of repeated transmissions by the candidate values ​​for the number of repeated transmissions in the second set of candidate values ​​for the number of repeated transmissions.

[0106] Optionally, the candidate values ​​for the number of repeated transmissions in the first set of candidate values ​​for the number of repeated transmissions and the second set of candidate values ​​for the number of repeated transmissions may be present in the form of a table or a list. The embodiment of the present application does not limit the organization form of the candidate values ​​for the number of repeated transmissions in the first set of candidate values ​​for the number of repeated transmissions and the second set of candidate values ​​for the number of repeated transmissions.

[0107] In a possible implementation, the second indication information is used to indicate activation or deactivation of HARQ feedback of the first HARQ process (or described as the second indication information is used to indicate the HARQ feedback state of the first HARQ process), and the first HARQ process includes all transport blocks (Transport Block, TB) scheduled by DCI or HARQ processes corresponding to some TBs. One TB can correspond to one HARQ process, and different TBs correspond to different HARQ processes. That is, when DCI is used to schedule one TB, the second indication information is used to indicate the HARQ feedback state of the HARQ process corresponding to the TB. When DCI is used to schedule multiple TBs, the second indication information is used to indicate the HARQ feedback state of the HARQ process corresponding to all or part of the multiple TBs. Exemplarily, taking DCI as an example for scheduling two TBs, the two TBs include TB1 and TB2, the second indication information can be used to indicate the HARQ feedback state of the HARQ process corresponding to TB1, or the second indication information can be used to indicate the HARQ feedback state of the HARQ process corresponding to TB1, and to indicate the HARQ feedback state of the HARQ process corresponding to TB2.

[0108] In a possible implementation, DCI is used to schedule multiple TBs, including the first TB; the network device may send a fifth indication information, and accordingly, the terminal device receives the fifth indication information, the fifth indication information being used to indicate support for activating or deactivating the HARQ feedback of the first HARQ process corresponding to the first TB through the second indication information (or described as: the fifth indication information is used to indicate support for indicating the HARQ feedback state of the first HARQ process corresponding to the first TB through the second indication information). Among them, the first TB may be part of the multiple TBs, in which case the second indication information is used to indicate the HARQ feedback state of the HARQ process corresponding to the part of the TBs scheduled by the DCI, and the part of the TB is the first TB. It can be understood that it can also be learned from the fifth indication information that the HARQ feedback state of the HARQ process corresponding to other TBs (hereinafter referred to as the second TB) in the multiple TBs other than the first TB is not supported through the second indication information, that is, the second indication information is not used to indicate the activation of the HARQ feedback of the HARQ process corresponding to the second TB, nor is it used to indicate the deactivation of the HARQ feedback of the HARQ process corresponding to the second TB. Optionally, the number of the first TB may be Z, and Z is a positive integer. Optionally, the first TB may be the first Z TBs among multiple TBs, or the first TB may be the last Z TBs among multiple TBs, which is not limited in the embodiments of the present application. For example, taking DCI used to schedule two TBs, the first TB is TB1, and the second TB is TB2 as an example, the network device may indicate that the first TB supports DCI dynamic activation or deactivation of HARQ feedback through the fifth indication information. Optionally, the fifth indication information may be high-level signaling, such as RRC signaling.

[0109] In a possible implementation, the terminal device may send the sixth indication information, and correspondingly, the network device receives the sixth indication information, the sixth indication information is used to indicate that the terminal device supports the calling voice service, or the sixth indication information is used to indicate that the service requested by the terminal device includes the calling voice service, or the sixth indication information is used to report the service type supported by the terminal device, and the service type supported by the terminal device includes the calling voice service, or the sixth indication information is used to indicate that the service type that the terminal device needs to be provided includes the calling voice service. Optionally, after receiving the sixth indication information, the network device may send the first indication information to the terminal device according to the sixth indication information. That is, the network device determines whether to send the first indication information to the terminal device according to whether the sixth indication information is received. The network device receives the sixth indication information and sends the first indication information to the terminal device; if the network device does not receive the sixth indication information, it may not send the first indication information to the terminal device.

[0110] Optionally, the sixth indication information may be carried in message 3 (Message 3, Msg3) in the four-step random access. The service type reported by the terminal device in Msg3 includes the calling voice service (MO-VOICE-CALL) type. Optionally, the network device learns through Msg3 that the terminal device needs to be provided with a calling voice service, and the network device may configure a data radio bearer (Data Radio Bearer, DRB) for the terminal device. Optionally, the DRB is in unacknowledged mode (UnacknowIedgedMode, UM) or acknowledged mode (acknowIededge Mode, AM).

Figure 5 As shown, the communication device 50 includes a receiving unit 501 and a sending unit 502. The communication device 50 can execute the relevant steps of the terminal device and the network device in the above method embodiment.
