Problems solved by technology

[0004] However, D2D communication has changed the traditional user-base station communication mode, and transplanted some functions of the base station to the user equipment, so whether it is from the physical layer, MAC (Media Access Control, medium access control) is a challenge

Abstract

The present disclosure relates to a user equipment, base station and method for conducting device-to-device communications. A wireless communication system at least comprises the user equipment of the present disclosure and another user equipment. The user equipment comprises a control unit; and a transmission unit which is controlled by the control unit and is used for transmitting control information to another user equipment by means of an uplink channel, wherein the control information comprises at least one of data transmission format information and power control information. According to the user equipment, base station and method of the present disclosure, the efficiency of communication between devices conducting device-to-device communications can be increased, thereby improving the data transmission performance.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a user equipment, a base station and a method for performing D2D (Device-to-Device, device-to-device) communication in a wireless communication system. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] The explosive growth of user data raises the requirements for data transmission rate and transmission efficiency. As the communication load between users and base stations continues to increase, direct communication between geographically adjacent devices without relaying through the base station can not only reduce the load on the base station, but also lead to better signals due to the small communication distance. Further, the transmission power between devices can be lower, which is beneficial to reduce communication interference to other devices....
