In various aspects of the following embodiments of the present application, the time unit is a slot as an example, but it is not limited to this, and the time unit may also be a frame or a subframe or a sub-slot.

In various aspects of the following embodiments of the present application, HARQ feedback information has the same meaning as HARQ-ACK information (HARQ-ACK information), where HARQ feedback information or HARQ-ACK information includes ACK information and NACK information.

The first aspect of the embodiment

The first aspect of the embodiments of the present application relates to a signal sending method, which is applied to a terminal device, such as the terminal device 102.

In the first aspect of the embodiments of the present application, the physical layer downlink data transmission of the terminal device 102 may have a reception feedback mechanism. The terminal device 102 will receive the physical downlink shared channel (PDSCH) at the specified time and frequency position according to the instructions (PDCCH) of the network device 101. At the same time, the terminal device 102 needs to make a corresponding hybrid automatic repeat request for the reception of the PDSCH (HARQ) feedback, where the indication of the network device 101 may be a physical downlink control channel (PDCCH).

For example, when the terminal device 102 successfully decodes the PDSCH, the HARQ feedback information that the terminal device 102 feeds back to the network device 101 is, for example, ACK information; when the terminal device 102 fails to decode the PDSCH, the terminal device 102 feeds back to the network device 101 The HARQ feedback information is, for example, NACK information.

By receiving the HARQ feedback from the terminal device 102, the network device 101 can determine which downlink data needs to be retransmitted accordingly, and can also determine the quality of the downlink channel according to the ratio of ACK information and NACK information in the HARQ feedback, thereby adjusting the modulation and coding of the downlink transmission the way.

In the first aspect of the embodiments of the present application, the scheduling of downlink data may at least include: dynamic scheduling (dynamic scheduling) and semi-persistent scheduling (SPS). Dynamic scheduling means that one PDCCH schedules one corresponding PDSCH. Semi-persistent scheduling means that a PDCCH can activate or deactivate a series of PDSCH transmissions, where the series of PDSCHs are repeatedly transmitted in the time domain with a period of P. When the terminal device 102 receives the activation signaling for semi-persistent scheduling, the terminal device 102 obtains the time-frequency position of the first PDSCH according to the indication in the PDCCH and the pre-configured indication, and then the terminal device 102 (without receiving the PDCCH) continues Periodically receive/monitor the PDSCH in the time domain. When the terminal device 102 receives the deactivation signaling of the semi-persistent scheduling, the terminal device 102 stops receiving the corresponding PDSCH.

Whether it is dynamic scheduling or semi-persistent scheduling, each PDSCH has corresponding HARQ feedback information, and the HARQ feedback information may be ACK information or NACK information.

Fig. 2 is a schematic diagram of dynamic scheduling in the first aspect of the embodiments of the present application. As shown in Figure 2, for dynamic scheduling, the downlink control information (DCI) 201 indicating the PDSCH 202 includes the first field, which is used to indicate the physical uplink control of the PDSCH and the bits carrying the corresponding HARQ feedback information The offset k between the channel (PUCCH) resources 203 (that is, the offset is k time units), the first field is, for example, a PDSCH-to-HARQ feedback timing indicator (PDSCH-to-HARQ_feedback timing indicator). For example, when the PDSCH 202 is in the time unit slot n, the corresponding HARQ feedback information is sent in the time unit slot n+k.

It should be noted that when the above time unit is a sub-slot, the PDSCH 202 in sub-slot n means that the end symbol of the PDSCH is in sub-slot n; the corresponding HARQ feedback information in sub-slot n+k is It means that the starting symbol of the PUCCH resource carrying this information is in sub-slot n+k; the PDSCH-to-HARQ_feedback timing indicator is used to indicate the sub-slot interval between the PDSCH and the corresponding HARQ feedback. The description here when the time unit is a sub-slot is also applicable to all aspects of the embodiments of the present application.

In addition, the DCI 201 may also include a PUCCH resource indicator (PUCCH resource indicator) field, which is used to indicate the PUCCH resource that carries the corresponding HARQ feedback information.

FIG. 3 is a schematic diagram of semi-persistent scheduling in the first aspect of the embodiments of the present application. As shown in Figure 3, for semi-persistent scheduling, the DCI 301 used to activate SPS may include a second field, which is used to indicate the difference between each PDSCH and the PUCCH resource carrying the corresponding HARQ feedback information bit. The offset k (that is, the offset is k time units), the second field is, for example, a PDSCH-to-HARQ feedback timing indicator (PDSCH-to-HARQ_feedback timing indicator). For example, as shown in Figure 3, the period of semi-persistent scheduling is P time units, PDSCH 302 is in time unit slot n, and the HARQ feedback information corresponding to PDSCH 302 is sent on PUCCH 303. The deviation between PDSCH 302 and PUCCH 303 is The shift is slot n+k; PDSCH 304 is in the time unit slot P+n, and the HARQ feedback information corresponding to PDSCH 304 is sent on PUCCH 305, and the offset between PDSCH 304 and PUCCH 305 is slot n+P+k .

In FIG. 3, the DCI 301 may indicate the PUCCH resource of the PUCCH 303 corresponding to the PDSCH 302 that is used to carry the bits of HARQ feedback information. In addition, DCI 301 (without semi-persistent scheduling configuration signaling) directly indicates the time-frequency domain resources of PDSCH 302. Therefore, PDSCH 302 is a PDSCH with a corresponding physical downlink control channel (with corresponding PDCCH).

In Figure 3, the DCI 301 does not directly indicate the time-frequency domain resources of the PDSCH 304. Therefore, the PDSCH 304 is a PDSCH without a corresponding physical downlink control channel (without corresponding PDCCH). If only the HARQ feedback information of PDSCH 304 needs to be sent in the time unit slot n+P+k where PUCCH 305 is located, then the terminal device 102 determines the PUCCH 305 used to carry HARQ feedback according to IE n1 PUCCH-AN information in the SPS configuration PUCCH resource of bits of information.

In Figure 3, the PDSCH 302 closest to DCI 301 in time is a PDSCH with a corresponding physical downlink control channel (with corresponding PDCCH), while the PDSCH 302 that is far away from DCI 301 in time has no corresponding physical downlink control channel (without corresponding PDCCH) PDSCH. The first aspect of the embodiments of the present application may not be limited to this. For example, the PDSCH 302 may also be set as a PDSCH without a corresponding physical downlink control channel (without corresponding PDCCH), and the PDSCH 302 may be set as having a corresponding physical downlink control channel (with corresponding PDCCH) PDSCH.

FIG. 4 is a schematic diagram of two or more HARQ feedback information being sent in the same time unit in the first aspect of the embodiments of the present application. As shown in Figure 4, DCI#1 is used to activate semi-persistent scheduling. PDCSH 402 is the PDSCH without corresponding physical downlink control channel (PDCCH) in the semi-persistent scheduling. The HARQ feedback information corresponding to PDSCH 402 is located at time Send on PUCCH 405 on unit slot n+P+k. DCI#2 is later than DCI#1, DCI#2 is used to activate dynamic scheduling, for example, DCI#2 indicates that HARQ feedback information corresponding to PDCSH 404 is also sent on PUCCH 405 located on the time unit slot n+P+k.

In FIG. 4, in order to avoid power loss, the HARQ feedback information bits corresponding to the semi-persistent scheduled PDSCH 402 and the HARQ feedback information bits corresponding to the dynamically scheduled PDCSH 404 are multiplexed in the same uplink resource. For example, the HARQ feedback information corresponding to PDSCH 402 and the HARQ feedback information corresponding to PDCSH 404 will be put together and sent on the resources of PUCCH 405 indicated by dynamic scheduling.

In addition, in FIG. 4, when the HARQ feedback information corresponding to different PDSCHs is sent in the same time unit, the terminal device 102 may determine the sequence of the HARQ feedback information corresponding to each PDSCH according to a predefined rule. In this way, a codebook of HARQ feedback information is generated. After the codebook is generated, the terminal device 102 will send an uplink signal for carrying the codebook. The uplink signal is, for example, a physical uplink control channel (PUCCH) or a physical uplink shared Channel (PUSCH) etc.

FIG. 5 is a schematic diagram of the signal sending method of the first aspect of the embodiments of the present application. As shown in FIG. 5, the signal sending method includes:

Operation 503: The terminal device 102 uses the uplink resource indicated by the first indication information to send an uplink signal including hybrid automatic repeat request (HARQ) feedback information corresponding to the first PDSCH.

As shown in FIG. 5, operation 502 is no later than operation 501.

In the case that the first indication information of semi-persistent scheduling is not earlier than the second indication information, the (without corresponding PDCCH) in the semi-persistent scheduling without corresponding physical downlink control channel is sent on the uplink resource indicated by the first indication information ) The hybrid automatic repeat request (HARQ) feedback information corresponding to the PDSCH, so that the uplink resource indication information corresponding to the semi-persistent scheduling indication information can override or update the uplink corresponding to the second indication information Resource indication; in this way, it is possible to flexibly and timely indicate the uplink resources of HARQ feedback information corresponding to the (without corresponding PDCCH) PDSCH in the semi-persistent scheduling without corresponding physical downlink control channel, thereby improving the reliability of HARQ feedback.

As shown in FIG. 6, the second indication information is used to indicate the reception of PDSCH#3. The HARQ feedback information corresponding to PDSCH#3 is sent in the time unit T2.

The first indication information is used for semi-persistent scheduling, and PDSCH#0, PDSCH#1 and the first indication information correspond to the same semi-persistent scheduling. PDSCH#0 and PDSCH#1 are both PDSCHs received by the terminal device 102. Wherein, PDSCH#1 is the first PDSCH, and PDSCH#1 is a (without corresponding PDCCH) PDSCH without a corresponding physical downlink control channel.

In FIG. 6, PDSCH#1 is the second PDSCH reception after the first indication information, but this application is not limited to this, and PDSCH#1 is not limited to the second PDSCH reception after the corresponding first indication information. It may be received according to periodically repeated PDSCH after the first indication information, where PDSCH#1 is before the next SPS activation or deactivation signaling, and the next SPS activation or deactivation signaling corresponds to the same first indication information. The SPS configuration ID.

In addition, receiving the first indication information by the terminal device 102 also means that the PUCCH resource indication corresponding to the first indication information overrides or updates (updates) the PUCCH resource indication corresponding to the second indication information.
