Transmission Method and Apparatus of Discovery Information and Communications System

Abstract

A transmission method and apparatus of discovery information and a communications system. The transmission method of discovery information includes: transmitting indication information indicating a size of discovery information by a user equipment to a base station; receiving one or more resources which is/are allocated by the base station according to the indication information; and transmitting the discovery information by using the one or more resources to perform sidelink discovery. Hence, a case of waste of resources or being unable to carry discovery information may be reduced as possible even if sizes of discovery information are different due to different scenarios.
