Multimode coordinated multipoint transmission with nonideal timing synchronization

Tongxin xuebao, 2016
Against the negative impact of non-ideal timing synchronization on the coordinated multipoint (CoMP) trans-mission, a multimode algorithm was proposed.

Distributed multicell beamforming scheme with limited intercell communication

Tongxin xuebao, 2012
Coordinated downlink beamforming optimization was studied for the time division duplexed(TDD)multicell system with limited inter-BS communication.With the objective to reach the particular point on the Pareto boundary of user rates with the maximum worst-

Understanding Noise and Interference Regimes in 5G Millimeter-Wave Cellular Networks

, 2016
With the severe spectrum shortage in conventional cellular bands, millimeter-wave (mmWave) frequencies have been attracting growing attention for next-generation micro- and picocellular wireless networks. A fundamental and open question is whether mmWave

Coordinated beamforming using semidefinite programming

2012 IEEE International Conference on Communications (ICC), 2012
In this paper, we study a coordinated beamforming (CBF) scheme for a multi-cell scenario where precoding/beamforming vectors for all coordinating base stations (BSs) are jointly designed in a manner that each BS transmits to its local users. We minimise the total transmit power across coordinating BSs while keeping the signal-to-interference-plus-noise

Practical decentralized high-performance coordinated beamforming

34th IEEE Sarnoff Symposium, 2011
Coordinated Beamforming (CBF) has been studied in hope of mitigating the inter-cell interference experienced by cell-edge users. Unfortunately, due to the limitations and/or impracticalities of the proposed designs, the expected performance gains have yet to be realized.

Coordinated beamforming with relaxed zero forcing

2011 International Conference on Wireless Communications and Signal Processing (WCSP), 2011
In this paper, a new beam design paradigm for coordinated beamforming (CB) for current and future cellular networks is proposed based on a relaxed zero-forcing (RZF) constraint. In the conventional zero-forcing (ZF) CB, each cooperating transmitter designs its transmit beamforming matrix to null out interference to undesired receivers completely.

Pragmatic multi-cell MIMO beamforming with decentralized coordination

2012 Conference Record of the Forty Sixth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2012
This paper considers a time division duplexing based coordinated multi-cell multiuser MIMO system. Optimization problem is sum power minimization among base stations (BSs) with minimum SINR constraint per each user. The problem is jointly non-convex with respect to transmit and receive beamformers.
