Adaptive Coordinated Reception for Multicell MIMO Uplink

Adaptive Coordinated Reception for Multicell MIMO Uplink

We study the coordinated reception amongst multiple base stations (BS) in the uplink cellular system, where each mobile station (MS) is served by an associated multiple BS set (MBS). Under the individual signal-to-interference-plus-noise ratio (SINR) constraint per MS, power control and receive beamforming are jointly optimized with adaptive MBS selection to minimize the total transmit power. A...

Resource Allocation and User Scheduling in Coordinated Multicell MIMO Systems

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...

Uplink Coordinated Multi-Point ARQ in MIMO Cellular Systems

Coordinated multi-point processing at multiple base stations can improve coverage, system throughput, and cell-edge throughput for future cellular systems. In this paper, we study the coordinated reception of transmitted signals at multiple MIMO base stations to exploit cooperative diversity. In particular, we propose to employ cooperative multicell automatic repeat request (ARQ) protocol via b...

Distributed user selection scheme for uplink multiuser MIMO systems in a multicell environment

We propose an interference-aware user selection scheme for uplink multiuser multiple-input multiple-output systems in a multicell environment. The proposed scheme works in a distributed manner. Each mobile station determines its transmit beamforming vector based on the locally available channel state information, and informs the associated base station (BS) of the amount of potential interferen...
