Abstract
A wireless communication method and a terminal device are provided. A first terminal device sends first information to a second terminal device, where the first information indicates that the second terminal device is to provide a first resource set, and the first resource set is used for the first terminal device to select a transmission resource.
Claims16
A wireless communication method, comprising:
- sending, by a first terminal device, first information to a second terminal device, wherein the first information indicates that the second terminal device is to provide a first resource set, and the first resource set is used for the first terminal device to select a transmission resource;
- receiving, by the first terminal device, the first resource set sent by the second terminal device;
- and
- selecting from the first resource set, by the first terminal device, N+1 resources for transmission of data on a target logical channel, wherein the N+1 resources comprise a resource for initial transmission of the data on the target logical channel and a resource for N hybrid automatic repeat request (HARQ) retransmissions of the data on the target logical channel, and N is a positive integer, wherein the first resource set is a resource set for the first terminal device;
- wherein any one of the N+1 resources can be indicated by a prior SCI, and an interval between any two adjacent resources in the N+1 resources is not less than a first interval when a physical sidelink feedback channel (PSFCH) resource is configured for a resource pool or when the first terminal device is to transmit an activated HARQ-acknowledgement (HARQ-ACK) feedback.

- receiving, by a second terminal device, first information sent by a first terminal device, wherein the first information indicates that the second terminal device is to provide a first resource set, and the first resource set is used for the first terminal device to select a transmission resource;
- wherein N+1 resources for transmission of data on a target logical channel will be selected by the first terminal device, wherein the N+1 resources comprise a resource for initial transmission of the data on the target logical channel by the first terminal device and a resource for N hybrid automatic repeat request (HARQ) retransmissions of the data on the target logical channel by the first terminal device, and N is a positive integer, wherein the first resource set is a resource set for the first terminal device;
- wherein any one of the N+1 resources can be indicated by a prior SCI, and an interval between any two adjacent resources in the N+1 resources is not less than a first interval when a physical sidelink feedback channel (PSFCH) resource is configured for a resource pool or when the first terminal device is to transmit an activated HARQ-acknowledgement (HARQ-ACK) feedback.
A terminal device, being operable as a first terminal device and comprising:
- a memory configured to store computer programs;
- a transceiver;
- and
- a processor configured to execute the computer programs stored in the memory to:
- cause the transceiver to send first information to a second terminal device, wherein the first information indicates that the second terminal device is to provide a first resource set, and the first resource set is used for the first terminal device to select a transmission resource;
- cause the transceiver to receive the first resource set sent by the second terminal device;
- and
- select N+1 resources for transmission of data on a target logical channel, wherein the N+1 resources comprise a resource for initial transmission of the data on the target logical channel and a resource for N hybrid automatic repeat request (HARQ) retransmissions of the data on the target logical channel, and N is a positive integer, wherein the first resource set is a resource set for the first terminal device;
- wherein any one of the N+1 resources can be indicated by a prior SCI, and an interval between any two adjacent resources in the N+1 resources is not less than a first interval when a physical sidelink feedback channel (PSFCH) resource is configured for a resource pool or when the first terminal device is to transmit an activated HARQ-acknowledgement (HARQ-ACK) feedback.
