Joint Base Station Clustering and Beamforming for Non-Orthogonal Multicast and Unicast Transmission with Backhaul Constraints
Erkai Chen, Meixia Tao, Ya-Feng Liu
The demand for providing multicast services in cellular networks is continuously and fastly increasing. In this work, we propose a non-orthogonal transmission framework based on la…
ADMM-based Fast Algorithm for Multi-group Multicast Beamforming in Large-Scale Wireless Systems
Erkai Chen, Meixia Tao
Multi-group multicast beamforming in wireless systems with large antenna arrays and massive audience is investigated in this paper. Multicast beamforming design is a well-known non…
Content-Centric Sparse Multicast Beamforming for Cache-Enabled Cloud RAN
Meixia Tao, Erkai Chen, Hao Zhou +1
This paper presents a content-centric transmission design in a cloud radio access network (cloud RAN) by incorporating multicasting and caching. Users requesting a same content for…
Content-Centric Multicast Beamforming in Cache-Enabled Cloud Radio Access Networks
Hao Zhou, Meixia Tao, Erkai Chen +1
Multicast transmission and wireless caching are effective ways of reducing air and backhaul traffic load in wireless networks. This paper proposes to incorporate these two key idea…
