Sidelink information sending method and receiving method, terminal, and control node

A sidelink information receiving method, applied to a control node and comprising:

• configuring codebook information of sidelink information for a terminal, wherein the codebook information comprises an occasion of a physical sidelink feedback channel (PSFCH) or an occasion of a scheduling signal used to schedule a sidelink transmission;
• and
• receiving a codebook from a terminal through a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH), wherein the codebook is corresponding to sidelink information,
• wherein the occasion of a physical sidelink feedback channel (PSFCH) or the occasion of a scheduling signal used to schedule a sidelink transmission is determined based on latency information, and the latency information comprises at least one of:
• a latency between a position of scheduling signaling and a position of sidelink transmission scheduled by the scheduling signaling;
• or
• a latency between a sidelink information feedback resource and a corresponding target resource, wherein the target resource is a PUCCH resource for sending the codebook.

A terminal, comprising a memory, a processor, and a program that is stored in the memory and that can be run by the processor, wherein when the program is executed by the processor, following steps of a sidelink information sending method are implemented:

• obtaining a codebook corresponding to sidelink information based on codebook information, wherein the codebook information comprises an occasion of a physical sidelink feedback channel (PSFCH) or an occasion of a scheduling signal used to schedule a sidelink transmission;
• and
• sending the codebook to a control node through a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH),
• wherein the occasion of a physical sidelink feedback channel (PSFCH) or the occasion of a scheduling signal used to schedule a sidelink transmission is determined based on latency information, and the latency information comprises at least one of:
• a latency between a position of scheduling signaling and a position of sidelink transmission scheduled by the scheduling signaling;
• or
• a latency between a sidelink information feedback resource and a corresponding target resource, wherein the target resource is a PUCCH resource for sending the codebook.
