Coordinated Multicast Beamforming in Multicell Networks [PDF]
IEEE Transactions on Wireless Communications, 2012 We study physical layer multicasting in multicell networks where each base station, equipped with multiple antennas, transmits a common message using a single beamformer to multiple users in the same cell.

Coordinated beamforming algorithm assisted by receive beamforming vector estimation
Tongxin xuebao, 2014 A distributed coordinated beamforming optimization scheme with the assistance of receive beamformer esti-mation was proposed for downlink cellular wireless communication systems. By sharing a small amount of information among cooperated base stations(BSs)

Deep Reinforcement Learning-Based Coordinated Beamforming for mmWave Massive MIMO Vehicular Networks
Sensors, 2023 As a critical enabler for beyond fifth-generation (B5G) technology, millimeter wave (mmWave) beamforming for mmWave has been studied for many years. Multi-input multi-output (MIMO) system, which is the baseline for beamforming operation, rely heavily on ...

Heuristic Coordinated Beamforming for Heterogeneous Cellular Network [PDF]
2016 IEEE 83rd Vehicular Technology Conference (VTC Spring), 2016 Heterogeneous cellular networks (HetNets) is key technology in 5G used to tackle the ever increasing demand of data rate. The most critical problem of HetNet is interference. In this paper, we utilize the coordinated beamforming technique to mitigate the interference problem.

Interference Pricing Mechanism for Downlink Multicell Coordinated Beamforming [PDF]
IEEE Transactions on Communications, 2014 We consider the downlink coordinated beamforming problem in a cellular network in which the base stations (BSs) are equipped with multiple antennas and each user is equipped with a single antenna. The BSs cooperate in sharing their local interference information, and they aim to maximize the sum-rate of the users in the network.

Coordinated beamforming in downlink CoMP transmission system [PDF]
Proceedings of the 5th International ICST Conference on Communications and Networking in China, 2010 Coordinated multi-point transmission/reception (CoMP) technique for 3GPP LTE-Advanced is to reduce the inter-cell interference (ICI) effectively, so as to enhance data rate/coverage and throughput for cell-edge users significantly. For downlink CoMP, most research work mainly focuses on joint processing/transmission (CoMP-JP) mode.
