Coordinated multicell beamforming for massive multiple-input multiple-output systems based on uplink-downlink duality

This paper studies joint beamforming and power allocation for multicell multiuser multi-antenna systems with the objective of maximising the minimum signal-to-interference-plus-noise ratio (max–min SINR). The authors first consider developing an iterative algorithm to achieve the optimal performance by extending the uplink–downlink duality for finite-scale wireless communication systems. The so...

Distributed Resource Allocation for Downlink Multicell OFDMA Systems

This paper addresses resource allocation for sum throughput maximization in a sectorized two-cell downlink OFDMA systems impaired by multicell interference. It is well known that the optimization problem for this scenario is NPhard and combinational, which is here converted to a novel sum throughput maximization problem based on the intercell interference limitation. Then, two subclasses of thi...

An efficient algorithm for weighted sum-rate maximization in multicell downlink beamforming

This paper considers coordinated linear precoding for rate optimization in downlink multicell, multiuser orthogonal frequencydivision multiple access networks. We focus on two different design criteria. In the first, the weighted sum-rate is maximized under transmit power constraints per base station. In the second, we minimize the total transmit power satisfying the signal-to-interference-plus...

Performance of OFDMA Multicell Systems with Opportunistic Beamforming

The opportunistic beamforming (OB) technique in multicellular OFDMA networks is investigated in this paper. Three cross-layer radio resource management (RRM) algorithms for OFDMA operational scenarios are considered. These algorithms build upon typical network planning practices for OFDMA systems. The first two implement an OFDMA network with opportunistic rate adaptation while the third one ai...

Efficient Channel Feedback Reduction Scheme for Multicell Cooperative Systems

In this paper, a feedback reduction scheme has been proposed for multicell cooperative system. Feedback bits are allocated to users by utilizing codebook rotation technique to prevent the waste of feedback resource. Simulation result shows that almost same sum rate can be achieved with less amount of feedback bits.
