Massive MIMO Multicasting in Noncooperative Multicell Networks

by Zhengzheng Xiang, Meixia Tao, Xiaodong Wangy
"... Abstract—We study the massive MIMO (multiple-input multiple-output) multicast transmission in multicell networks, where each base station (BS) is equipped with a large-scale antenna array and transmits a common message using a single beamformer to multiple mobile users. We first consider the case wh ..."
