Abstract

A data transmission method and an apparatus are provided. When a time-frequency resource used by a terminal device for data transmission is unavailable, the terminal device postpones, based on indication information of a network device and/or according to a postponement rule, the data transmission to a time-frequency resource closest to the time-frequency resource. Therefore, a data transmission latency is reduced.

Claims (36)

1 . A data transmission method applied to a data transmission apparatus, wherein the method comprises:

receiving first indication information from a network device, wherein the first indication information comprises configuration information of a first time-frequency resource;

receiving second indication information from the network device, wherein the second indication information indicates whether to use a postponement rule, wherein the postponement rule is predefined;

based on determining that the first time-frequency resource overlaps a downlink slot or a downlink symbol in time domain, determining a second time-frequency resource based on the second indication information and according to the postponement rule, wherein a time domain position of the second time-frequency resource is after a time domain position of the first time-frequency resource; and

sending uplink data to the network device on the second time-frequency resource, or receiving downlink data from the network device on the second time-frequency resource.

2 . The method according to claim 1 , wherein the first time-frequency resource is a configured grant (CG) or a downlink semi-persistent scheduling (SPS) resource.

3 . The method according to claim 1 , wherein the second indication information comprises one or more bits to indicate whether to use the postponement rule.

4 . The method according to claim 3 , wherein each bit among the one or more bits corresponds to a Media Access Control (MAC) entity among one or more MAC entities, and wherein the bit indicates whether a terminal device uses the postponement rule for the corresponding MAC entity among the one or more MAC entities.

5 . The method according to claim 3 , wherein each bit among the one or more bits corresponds to a configured grant (CG) among one or more CGs, and wherein a bit indicates whether the terminal device uses the postponement rule for the corresponding CG among the one or more CGs.

6 . The method according to claim 3 , wherein each bit among the one or more bits corresponds to a logic channel among one or more logic channels, and wherein the bit indicates whether a terminal device uses the postponement rule for the corresponding logic channel among the one or more logic channels.

7 . The method according to claim 1 , wherein a hybrid automatic repeat request (HARQ) process number corresponding to the second time-frequency resource is the same as a HARQ process number corresponding to the first time-frequency resource.

8 . A data transmission method applied to a data transmission apparatus, wherein the method comprises:

sending first indication information to a terminal device, wherein the first indication information comprises configuration information of a first time-frequency resource;

sending second indication information to the terminal device, wherein the second indication information indicates whether to use a postponement rule by the terminal device, wherein the postponement rule is predefined;

based on determining the first time-frequency resource overlaps a downlink slot or a downlink symbol in time domain, determining a second time-frequency resource according to the first time-frequency resource and the postponement rule, wherein a time domain position of the second time-frequency resource is after a time domain position of the first time-frequency resource; and

receiving uplink data from the terminal device on the second time-frequency resource, or sending downlink data to the terminal device on the second time-frequency resource.

9 . The method according to claim 8 , wherein the first time-frequency resource is a configured grant (CG) or a downlink semi-persistent scheduling (SPS).

10 . The method according to claim 8 , wherein a hybrid automatic repeat request (HARQ) process number corresponding to the second time-frequency resource is the same as a HARQ process number corresponding to the first time-frequency resource.

11 . A data transmission apparatus comprising:

at least one processor; and

a memory coupled to the at least one processor and configured to store executable instructions for execution by the at least one processor to instruct the at least one processor to:

receive first indication information from a network device, wherein the first indication information comprises configuration information of a first time-frequency resource;

receive second indication information from the network device, wherein the second indication information indicates whether to use a postponement rule, wherein the postponement rule is predefined;

based on determining that the first time-frequency resource overlaps a downlink slot or a downlink symbol in time domain, determine a second time-frequency resource based on the second indication information and according to the postponement rule, wherein a time domain position of the second time-frequency resource is after a time domain position of the first time-frequency resource; and

send uplink data to the network device on the second time-frequency resource, or receive downlink data from the network device on the second time-frequency resource.

12 . The apparatus according to claim 11 , wherein the first time-frequency resource is a configured grant (CG) or a downlink semi-persistent scheduling (SPS) resource.

13 . The apparatus according to claim 11 , wherein a hybrid automatic repeat request (HARQ) process number corresponding to the second time-frequency resource is the same as a HARQ process number corresponding to the first time-frequency resource.

14 . A data transmission apparatus comprising:

at least one processor; and

a memory coupled to the at least one processor and configured to store executable instructions for execution by the at least one processor to instruct the at least one processor to:

send first indication information to a terminal device, wherein the first indication information comprises configuration information of a first time-frequency resource;

send second indication information to the terminal device, wherein the second indication information indicates whether to use a postponement rule by the terminal device, wherein the postponement rule is predefined;

based on determining the first time-frequency resource overlaps a downlink slot or a downlink symbol in time domain, determine a second time-frequency resource according to the first time-frequency resource and the postponement rule, wherein a time domain position of the second time-frequency resource is after a time domain position of the first time-frequency resource; and

receive uplink data from the terminal device on the second time-frequency resource, or send downlink data to the terminal device on the second time-frequency resource.

15 . The apparatus according to claim 14 , wherein the first time-frequency resource is a configured grant (CG) or a downlink semi-persistent scheduling (SPS).

16 . The apparatus according to claim 14 , wherein a hybrid automatic repeat request (HARQ) process number corresponding to the second time-frequency resource is the same as a HARQ process number corresponding to the first time-frequency resource.
