内容摘要：Future 5G networks and beyond expect a fast expansion of wireless services, with massive content distribution over the wireless networks to serve enhanced mobile broadband and smart cities enabled by Internet of Things. The growing demands and stringent requirements require enabling wireless communication technologies for massive data dissemination at ultra-high speed with high efficiency and low cost. Multi-antenna multicast beamforming has received growing attentions as an efficient physical-layer technique for common content distribution. Its importance is further magnified by the recent development of wireless caching systems which rely on multicasting for coded delivery. In this talk, Prof. Dong will present their recent works on content multicasting via efficient multi-antenna multicast beamforming. A primary challenge for multicast beamforming is the elusive optimal solution due to the NP-hard nature of the problem. Existing numerical methods theoretically are unable to offer fundamental understanding of the beamforming structure for multicasting, and practically suffer from high computational complexity and performance degradation for large-scale systems such as massive MIMO and high user population. To break this barrier, Prof. Dong will describe the fundamental structure of optimal multicast beamforming for interference mitigation in multi-group multicasting, how its inherent low-dimensional structure benefits the multicast beamforming design for massive MIMO systems, and numerical algorithms to compute the solution. Prof. Dong will further discuss a few low-complexity multicast beamforming methods for massive MIMO multi-cell network environments.
