Abstract

The present disclosure relates to an information transmission method, a terminal device, and a network device. The method includes determining N uplink resources used to carry N sets of uplink feedback information. The N sets of uplink feedback information is used to feed back data transmission conditions in N sets of downlink resources. The i-th set of uplink feedback information corresponding to the i-th uplink resource is used to feed back the data transmission condition in the i-th set of downlink resources, when i is greater than 1. The i-th set of downlink resources include some or all of the (i−1)-th set of downlink resources, where N is a positive integer greater than 1, and i=1, 2, 3, . . . , N. The method also includes determining M available uplink resources in the N uplink resources, where M is a positive integer less than or equal to N. The method further includes using the M available uplink resources to send, to the network device, M sets of uplink feedback information corresponding to the M available uplink resources.

First claim

What is claimed is:

1. A method for information transmission, comprising:
determining M available uplink resources from N uplink resources, wherein the N uplink resources are used for carrying N sets of uplink feedback information, an i-th set of uplink feedback information is used for indicating data transmission condition in an i-th set of downlink resources, and when i is greater than 1, the i-th set of downlink resources includes all of an (i−1)-th set of downlink resources, where N is a positive integer greater than 1, i=1, 2, 3, 4, . . . , N, and M is a positive integer less than or equal to N; and
transmitting, through the M available uplink resources, M sets of uplink feedback information corresponding to the M available uplink resources.

2. The method according to claim 1 , wherein, when i is greater than 1, the i-th set of uplink feedback information includes all of an (i−1)-th set of uplink feedback information.

3. The method according to claim 1 , wherein an end time of the i-th set of downlink resources is before a start time of the i-th uplink resource.

4. The method according to claim 1 , wherein a time difference between an end time of the i-th set of downlink resources and a start time of the i-th uplink resource is greater than or equal to a processing delay, and the processing delay is determined according to time used for processing data transmitted by occupying the i-th set of downlink resources.

5. The method according to claim 4 , wherein the processing delay is determined according to one of decoding time of physical downlink shared channel (PDSCH) transmitted by occupying the i-th set of downlink resources and a physical channel carrying the i-th set of uplink feedback information.

6. The method according to claim 1 , wherein the determining M available uplink resources from the N uplink resources comprises:
determining the M available uplink resources from the N uplink resources through listen-before-talk (LBT) detection.

7. The method according to claim 1 , wherein a start time of the i-th uplink resource is determined according to an end position of the N sets of downlink resources.

8. The method according to claim 1 , wherein the N uplink resources are located on a grant-free carrier.

9. The method according to claim 1 , wherein, before the determining M available uplink resources from the N uplink resources, further comprises:
determining that at least one piece of downlink data is received on the N sets of downlink resources.

10. A terminal device, comprising: a processor, a memory, and a transceiver, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory;
the processor is further configured to determine M available uplink resources from N uplink resources, wherein the N uplink resources are used for carrying N sets of uplink feedback information, an i-th set of uplink feedback information is used for indicating data transmission condition in an i-th set of downlink resources, and when i is greater than 1, the i-th set of downlink resources includes all of an (i−1)-th set of downlink resources, where N is a positive integer greater than 1, i=1, 2, 3, 4, . . . , N, and M is a positive integer less than or equal to N; and
the transceiver is configured to transmit, through the M available uplink resources, M sets of uplink feedback information corresponding to the M available uplink resources.

11. The terminal device according to claim 10 , wherein, when i is greater than 1, the i-th set of uplink feedback information includes all of an (i−1)-th set of uplink feedback information.

12. The terminal device according to claim 10 , wherein an end time of the i-th set of downlink resources is before a start time of the i-th uplink resource.

13. The terminal device according to claim 10 , wherein a time difference between an end time of the i-th set of downlink resources and a start time of the i-th uplink resource is greater than or equal to a processing delay, and the processing delay is determined according to time used for processing data transmitted by occupying the i-th set of downlink resources.

14. The terminal device according to claim 13 , wherein the processing delay is determined according to one of decoding time of physical downlink shared channel (PDSCH) transmitted by occupying the i-th set of downlink resources and a physical channel carrying the i-th set of uplink feedback information.

15. The terminal device according to claim 10 , wherein the processor is further configured to:
determine the M available uplink resources from the N uplink resources through listen-before-talk (LBT) detection.

16. The terminal device according to claim 10 , wherein a start time of the i-th uplink resource is determined according to an end position of the N sets of downlink resources.

17. The terminal device according to claim 10 , wherein the N uplink resources are located on a grant-free carrier.

18. The terminal device according to claim 10 , wherein the processor is further configured to:
determine, before determining the M available uplink resources from the N uplink resources, that at least one piece of downlink data is received on the N sets of downlink resources.

19. A non-transitory computer-readable storage medium for storing a computer program that causes a computer to perform an information transmission method, wherein the method comprises:
determining M available uplink resources from N uplink resources, wherein the N uplink resources are used for carrying N sets of uplink feedback information, an i-th set of uplink feedback information is used for indicating data transmission condition in an i-th set of downlink resources, and when i is greater than 1, the i-th set of downlink resources includes all of an (i−1)-th set of downlink resources, where N is a positive integer greater than 1, i=1, 2, 3, 4, . . . , N, and M is a positive integer less than or equal to N; and
