Abstract

This paper studies adaptive coordinated control of device-to-device (D2D) communications underlaying a cellular network with a multi-antenna base station (BS). We analyze the performance of cellular and D2D users under the channel imperfections including both quantization error and feedback delay. More specifically, we derive the received signal-to-interference-and-noise ratio (SINR) distributions of both D2D and cellular users. Based upon this, we further obtain a closed-form approximation of the achievable rate, which serves as a theoretical support for choosing transmit beamforming strategies adaptively.
