Interference Coordination through Network-Synchronized Cyclic Beamforming
2009 IEEE 70th Vehicular Technology Conference Fall, 2009The next generation of wireless networks (e.g., (10)) will use multiple techniques to improve channel spectral efficien- cies. In this paper we focus on one such technique, beamforming, in the downlink channel. In each sector, a number of fixed beams are used to serve UEs (User Equipment).

Cell Selection Algorithm Based on Coordinated Beamforming
Advanced Materials Research, 2014In LTE-A (LTE-Advanced) system, CoMP (Coordinated Multipoint Transmission) is used to improve system capacity and cell coverage. CB(Coordinated Beamforming), as a way of CoMP, using multi-cell coordination to improve the spectrum efficiency of edge users. Therefore, coordinated cell selection is important.

CoBF: Coordinated Beamforming in Dense mmWave Networks
Proceedings of the ACM on Measurement and Analysis of Computing Systems, 2023With MIMO and enhanced beamforming features, IEEE 802.11ay is poised to create the next generation of mmWave WLANs that can provide over 100 Gbps data rate. However, beamforming between densely deployed APs and clients incurs unacceptable overhead.

Coordinated beamforming in MIMO FBMC/OQAM systems
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014In this contribution, we propose a coordinated transmit beamforming technique for point-to-point multiple-input-multiple-output (MIMO) filter bank based multi-carrier with offset quadrature amplitude modulation (FBMC/OQAM) systems. To enable reliable transmissions when the number of transmit antennas does not exceed the number of receive antennas and ...

Low complexity coordinated beamforming using interference alignment
2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013This paper investigates low complexity coordinated beamforming (CB) schemes that adopt interference alignment (IA). The majority of existing IA CB schemes rely on iterative solutions that have drawbacks such as sensitivity to initialization conditions, high computational complexity, and infeasible system requirements.

Inter‐cell coordinated beamforming with opportunistic scheduling
International Journal of Communication Systems, 2015SummaryThis paper proposes a distributed coordination framework with opportunistic scheduling among multiple users as opposed to the existing works on the multiple‐cell cooperative beamforming problem that deals with a single active user in each cell.

Distributed implementation of coordinated multi-cell beamforming
2009 IEEE 20th International Symposium on Personal, Indoor and Mobile Radio Communications, 2009A distributed implementation of coordinated multi-cell beamforming with single-antenna users in a time-correlated fading scenario is considered. The minimum power beamformers are obtained locally at each base station (BS) relying on limited backhaul information exchange between adjacent BSs.

Coordinated Beamforming of CoMP with Limited Feedback
2011 International Conference on Network Computing and Information Security, 2011The performance of LTE-Advanced systems which is based on orthogonal frequency division multiplexing (OFDM) is significantly restricted by inter-cell interference(ICI). Advancing the performance of cell edge users who experienced strong ICI is still a crucial issue.

Coordinated Beamforming for Multicell Multicast Secret Communications
2018 IEEE 88th Vehicular Technology Conference (VTC-Fall), 2018In this paper, we study the optimal transmitter beamforming design in a coordinated multicell multicast network under the wiretap channel model, where each cell serves a group of users and a single-antenna eavesdropper tries to overhear the confidential information.

Inter-cell coordinated beamforming with opportunistic scheduling
2013 IEEE International Conference on Communications (ICC), 2013This paper proposes a distributed coordination framework with opportunistic scheduling among the multiple users as opposed to the existing works on the multi-cell cooperative beamforming problem subject to a single active user in each cell. This framework deals with the best throughput trade-off between throughput gain by interference nulling, and ...
