In this paper, we study multiple-input single-output downlink cellular systems which jointly design adaptive inter-cell interference cancellation and user scheduling assuming that partial channel state information (CSI) is shared among base stations (BSs). Since the optimal solution requires high complexity, we propose a new low complexity algorithm which selects the best users and their beamforming...
Coordinated multipoint transmission (CoMP) is considered for a heterogeneous network where different kinds of base stations (BS) are located. We focus on linear transceiver design including user scheduling with the goal of maximizing the weighted sum rate in the downlink of a multiple-input multiple-output orthogonal frequency division multiple access (MIMO-OFDMA) system, where each subchannel is...
This work considers the problem of multiuser transmission in a downlink transmission system where a transmitter with multiantenna elements sends information to a set of scheduled users with each having a single antenna. We investigate the sum rate performance of an orthogonal beamforming (OBF) scheme called adaptive OBF, which is a suboptimal low-complexity alternative to the capacity-achieving dirty...
