We propose an auction-based beamforming and user association algorithm for a wireless network consisting of a macrocell and multiple small cell access points (SCAs). The SCAs compete for serving the macrocell base station (MBS) users (MUs). The corresponding user association problem is solved by the proposed bid-wait auction method. The authors considered two scenarios. In the first scenario, the...
The authors propose a game-theoretic approach for the downlink beamformer design for a multiuser multi-cell wireless network under a mixed quality of services (QoS) criterion. The network has real time users (RTUs) that must attain a specific set of signal-to-interference-plus-noise ratios (SINRs), and non-RTUs whose SINRs should be balanced and maximised. They propose a mixed QoS strategic non-cooperative...
In this paper, we study a downlink wireless network consisting of wireless powered communication (WPC) system and a simultaneously wireless information and power transfer (SWIPT) systems. The SWIPT system simultaneously serves one information receiver (IR) while transferring power to a wireless device (WD). The wireless powered system consists of the WD and its IR. Both systems operate on the same...
We propose optimization techniques for coordinated multi-cell beamforming in the presence of local users and a global user. The local users are served by only the corresponding basestation (BS) while the global user is served by multiple basestations. The global user, with the aid of multiple antennas, is able to decode multiple data streams transmitted by various transmitters through singular value...
In this work, we demonstrate how the bargain region can be extended by using mixed quality-of-service (QoS) optimization in a two-user game. We show that the bargain region extension is linked with a new Nash equilibrium (NE) point, which we call the NE-mixed QoS. We studied the performance of two systems from game-theoretic perspective. The first one considered a situation where both players want...
This work outlines how mixed quality-of-service (QoS) optimization in multi-cell coordinated beamforming (MCBF) can be effectively implemented using distributed algorithms. An alternating direction method of multipliers (ADMM) based algorithm has been adopted to provide distributed beamformer design based on the joint signal-to-interference-plus-noise ratio (SINR) balancing and SINR-target criterion...
