Method and apparatus for determining parameter values

Abstract

The embodiment of the present invention discloses a method and device for determining a parameter value, including: if the current moment is the parameter value adjustment moment, then determine the target value of the target parameter at the current moment according to the target method, and the target parameter includes an interference threshold and a signal strength threshold , channel occupancy rate threshold, channel busy rate threshold and distance threshold, and the target method is one of the following: determine the number of targets according to the target mapping relationship, and the target mapping relationship includes the value of the target parameter and the first target information. Mapping relationship, the first target information includes at least one of target duration, target duration ratio, counter value and retransmission times; and, adjust the step size according to the initial value and value of the target parameter, determine the target value, the initial The value is related to the first target information. The method in the embodiment of the present invention can improve the probability that a terminal device selects a suitable resource.

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.
