## Abstract

An apparatus and method in a wireless communication system, and a computer-readable storage medium The method comprises: determining, based on at least one or more of resource set configuration information, physical channel information, and service type information, configuration information of one or more parameter sets for a sidelink communication; and controlling a base station to send the determined configuration information of the one or more parameter sets to a user equipment so that the user equipment performs sidelink communication on the basis of the one or more parameter sets, the parameter set comprising at least a subcarrier interval and a cyclic prefix type. The method can flexibly configure the parameter set used for the sidelink communication in NR so as to improve the communication performance of the sidelink communication and meet higher requirements on a series of indicators in an NR scene such as the delay and the system stability.
