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.
