Resource selection method and apparatus, electronic device and storage medium

An electronic device, comprising:

• a processor, a memory, and a transceiver, the processor, the memory, and the transceiver communicating with each other through an internal connection path, wherein:
• the memory stores program code;
• and
• the processor calls the program code stored in the memory to cooperate with the transceiver to:
• compare a reference signal received power (RSRP) of a channel with a preset received power threshold if a maximum number of demodulation reference signal (DMRS) ports corresponding to a physical sidelink shared channel (PSSCH) is at least two;
• wherein the channel is a physical sidelink control channel (PSCCH) sensed by a user equipment (UE) or a PSSCH scheduled by the PSCCH sensed by the UE, and the maximum number of DMRS ports is a maximum number of DMRS ports of the PSSCH scheduled by the PSCCH sensed by the UE, or a maximum number of DMRS ports of a PSSCH transmitted in a resource pool used by the UE;
• and
• determine whether to perform resource exclusion in a resource selection window of the UE according to a comparison result;
• wherein the maximum number of DMRS ports corresponding to the PSSCH being at least two, comprises:
• the resource pool used by the UE is configured as that an RSRP of a PSSCH scheduled by a sensed PSCCH is used to compare with the received power threshold;
• and
• a field corresponding to a number of DMRS ports in sidelink control information (SCI) transmitted in the PSCCH sensed by the UE is a preset value.

A computer-readable storage medium with a computer program stored thereon, wherein the computer program, when executed by a processor, causes the processor to execute the following:

• comparing a reference signal received power (RSRP) of a channel with a preset received power threshold if a maximum number of demodulation reference signal (DMRS) ports corresponding to a physical sidelink shared channel (PSSCH) is at least two;
• wherein the channel is a physical sidelink control channel (PSCCH) sensed by a user equipment (UE) or a PSSCH scheduled by the PSCCH sensed by the UE, and the maximum number of DMRS ports is a maximum number of DMRS ports of the PSSCH scheduled by the PSCCH sensed by the UE or a maximum number of DMRS ports of a PSSCH transmitted in a resource pool used by the UE;
• and
• determining whether to perform resource exclusion in a resource selection window of the UE according to a comparison result;
• wherein the maximum number of DMRS ports corresponding to the PSSCH being at least two, comprises:
• the resource pool used by the UE is configured as that an RSRP of a PSSCH scheduled by a sensed PSCCH is used to compare with the received power threshold;
• and
• a field corresponding to a number of DMRS ports in sidelink control information (SCI) transmitted in the PSCCH sensed by the UE is a preset value.
