1. A sidelink congestion control method, applied to a first terminal and comprising:
receiving a physical-layer priority mapping rule from a network side device, wherein the physical-layer priority mapping rule comprises at least one of: a mapping relationship between one or more service quality identifiers of the first terminal and physical-layer priorities, and one or more priority values and physical-layer priorities; and
determining a physical-layer priority of the first terminal according to the physical-layer priority mapping rule; wherein
the physical-layer priority is used for determining a transmission resource for the first terminal;
if a measured RSRP value of a resource indicated by a received sidelink control information (SCI) is less than a SL-RSRP threshold, the first terminal does not perform resource reselection;
if the measured RSRP value of the resource indicated by the received SCI is greater than or equal to the SL-RSRP threshold, the first terminal performs resource reselection.
