Abstract: A method for resource configuration includes determining that a first resource and a second resource are multiplexed in a first target mode. The first resource is a candidate resource, on the SL, configured to transmit control information. The second resource is a candidate resource, on the SL, configured to transmit data. The first target mode is time-division multiplexing (TDM) or frequency-division multiplexing (FDM).

Abstract: A method for determining a parameter value includes: in a case that a current time is a parameter value adjustment time, determining a target numerical value of a target parameter at the current time according to a target mode. The target parameter includes at least one of an interference threshold, a signal strength threshold, a channel occupancy rate threshold, a channel busy rate threshold or a distance threshold. The target mode is at least one of: determining the target numerical value according to a target mapping relationship; or according to an initial value of the target parameter and a numerical value adjustment step length, determining the target numerical value.

Abstract: Embodiments of this disclosure disclose a method for sidelink rate matching and resource mapping and a device, so as to provide a solution to rate matching and resource mapping for sidelink communication. The method is executed by a terminal device and includes: calculating, based on a resource size of a target resource, a length E of coded bits carriable by a usable resource with the target resource excluded; and performing resource mapping based on a coded bit sequence output by rate matching, where a length of the coded bit sequence is equal to E or equal to E+E′, and E′ is a length of coded bits carriable by the target resource.
