Due to wireless propagation condition, users in a cell experience different channel condition. Thus cell-center users have optimal condition whereas cell-edge users suffer from a severe path-loss and a low bit-rate. In this paper, a fair scheme to allocate Resource Blocks (RB) on the downlink in LTE networks is proposed. The problem addresses maximising the overall system throughput while ensuring...
With MIMO antennas, the beamforming technique improves the received signal power which increases the RB's capacity and reduces the neighbouring cell users' interference on the cell edge, but the performance of the beamforming technique on a frequency depends on all the channels of involved UEs (User Equipment). We explain that a smart UE scheduling can increase the capacity improvement with the beamforming...
Multi-cell cooperation has been regarded as a promising technique of the future cellular wireless network to achieve higher transmission rate and better QoS (quality of service) performance. Cooperation among base stations can be classified into two categories: centralized and distributed cooperation. In this work, we mainly consider efficient and practical cooperation clustering approaches in the...
In this paper, power allocation scheme for clusters by mobile station (MS) is investigated in the uplink of a multi-user multiple-input multiple-output (MU-MIMO) and orthogonal frequency division multiplexing access (OFDMA) cellular system. In system level simulation works, without the knowledge of how many clusters will be assigned to a MS, it is a puzzle to decide how much transmission power should...
