Method for determining parameter value, and equipment

Abstract

The embodiment of the invention discloses a method for determining a parameter value, and equipment. The method comprises the following steps: if a current moment is a parameter value adjustment moment, determining a target value of target parameters at the current moment according to the target mode, wherein the target parameters comprise at least one of an interference threshold, a signal strength threshold, a channel occupancy rate threshold, a channel busy rate threshold and a distance threshold, and the target mode is one of the following modes: determining a target number according to atarget mapping relationship, the target mapping relationship comprising a mapping relationship between the value of the target parameters and first target information, and the first target informationcomprising at least one of a target duration, a target duration proportion, a value of a counter and a retransmission frequency; and determining a target numerical value according to the initial value of the target parameters and the numerical value adjustment step length, the initial value of the target parameters being related to the first target information. According to the method provided bythe embodiment of the invention, the probability that terminal equipment selects proper resources can be improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and more particularly to a method and device for determining parameter values. Background technique [0002] A side link (Sidelink) refers to a link between a terminal equipment (User Equipment, UE) and the UE for direct communication without going through a network. Long Term Evolution (LTE) Sidelink includes Device to Device (Device to Device, D2D) communication and Vehicle to Everything (V2X) communication. New air interface (New Radio, NR) Sidelink currently includes V2X communication. Two resource allocation modes are supported in LTE Sidelink: scheduling resource allocation mode and UE autonomous resource selection mode. In the scheduling resource allocation mode, the network device configures resources for Sidelink; in the UE autonomous resource selection mode, the UE will periodically reserve certain resources based on the monitoring results for a period of time.
