Method and device for determining a parameter value

A user equipment, applied to sidelink communication, comprising:

• a memory, a processor and a program which is stored in the memory and executable on the processor, wherein the program, when executed by the processor, causes the processor to perform:
• 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, wherein the target parameter comprises 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, wherein the target mapping relationship comprises a mapping relationship between a value of the target parameter and first target information, and the first target information comprises at least one of a target time length, a target time length ratio, a value of a counter or the number of times of retransmission;
• or
• according to an initial value of the target parameter and a numerical value adjustment step length, determining the target numerical value, wherein the initial value of the target parameter is related to the first target information.
