Abstract

Claims (37)

1 . A wireless communication method, comprising:

receiving, by a first terminal, sidelink data sent by a second terminal on multiple carriers; and

selecting, by the first terminal, at least one carrier for transmission a physical sidelink feedback channel (PSFCH) according to a channel busy ratio (CBR),

wherein, the PSFCH is configured to carry sidelink feedback information of the sidelink data on the multiple carriers,

wherein the method further comprises:

determining, by the first terminal, a set formed by carriers whose CBR is smaller than a first threshold among the multiple carriers as a third carrier set; and

selecting, by the first terminal, at least one carrier for transmission the PSFCH from the third carrier set.

2 . The method according to claim 1 , wherein the at least one carrier for transmission the PSFCH is further selected according to multiple carriers, and the method comprises:

selecting, by the first terminal, at least one carrier for transmitting the PSFCH among the multiple carriers.

3 . The method according to claim 1 , wherein the at least one carrier for transmission the PSFCH is further selected according to first indication information, and the first indication information is configured to indicate at least one carrier for transmitting the PSFCH, and the method further comprises:

selecting, by the first terminal, at least one carrier for transmitting the PSFCH according to the index information.

4 . The method according to claim 3 , wherein the index information is carrier index information, and the selecting, by the first terminal, at least one carrier for transmitting the PSFCH according to the index information, comprises:

selecting, by the first terminal, a carrier corresponding to the carrier index information as the carrier for transmitting the PSFCH.

5 . The method according to claim 1 , wherein the at least one carrier for transmission the PSFCH is further selected according to carrier configuration information of the PSFCH, and wherein the carrier configuration information of the PSFCH is used to configure a first carrier set for transmitting the PSFCH.

6 . The method according to claim 1 , wherein the selecting, by the first terminal, at least one carrier for transmission the PSFCH from the third carrier set, comprises:

selecting, by the first terminal, at least one carrier for transmission the PSFCH from the third carrier set in an order of CBR from low to high.

7 . The method according to claim 1 , wherein the selecting, by the first terminal, at least one carrier for transmission the PSFCH from the third carrier set, comprises:

determining, by the first terminal, a first intersection set of the third carrier set and a fourth set of carriers formed by the multiple carriers; and

selecting, by the first terminal, at least one carrier for transmission the PSFCH from the first intersection set.

8 . The method according to claim 1 , wherein the selecting, by the first terminal, at least one carrier for transmission the PSFCH from the third carrier set, comprises:

determining, by the first terminal, a second intersection set of the third carrier set and a fifth carrier set, wherein the fifth carrier set is a carrier set formed by at least one carrier indicated by the first indication information; and

selecting, by the first terminal, at least one carrier for transmission the PSFCH from the second intersection set.

9 . The method according to claim 1 , wherein the selecting, by the first terminal, at least one carrier for transmission the PSFCH from the third carrier set, comprises:

determining, by the first terminal, a third intersection set of the third carrier set and a first carrier set, wherein the first carrier set is a carrier set configured by the carrier configuration information of the PSFCH; and

selecting, by the first terminal, at least one carrier for transmission the PSFCH from the third intersection set.

10 . The method according to claim 1 , wherein the sidelink data sent on the multiple carriers comprises: sidelink data sent simultaneously, and/or sidelink data not sent simultaneously.

11 . The method according to claim 1 , wherein the sidelink data sent on the multiple carriers belong to a same data block or different data blocks.

12 . The method according to claim 1 , wherein the sidelink feedback information corresponding to the sidelink data sent on the multiple carriers is carried on one PSFCH, or carried on different PSFCHs.

13 . The method according to claim 1 , wherein the carrier for transmitting the first sidelink data is different from the carrier for transmitting the PSFCH corresponding to the first sidelink data; and

wherein, the first sidelink data is one piece of sidelink data among the sidelink data sent on the plurality of carriers.

14 . A terminal device, comprising: a processor and a memory, 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, to execute a wireless communication method, comprising:

receiving, by the terminal device, sidelink data sent by a second terminal on multiple carriers; and

selecting, by the terminal device, at least one carrier for transmission a physical sidelink feedback channel (PSFCH) according to a channel busy ratio (CBR),

wherein, the PSFCH is configured to carry sidelink feedback information of the sidelink data on the multiple carriers

wherein the processor is further configured to:

determine a set formed by carriers whose CBR is smaller than a first threshold among the multiple carriers as a third carrier set; and

select at least one carrier for transmission the PSFCH from the third carrier set.
