POWER CONTROL OPTIMIZATION FOR LTE-ADVANCED RELAY NETWORKS

Relay nodes (RNs) promise to increase the network capacity and to better distribute resources in the cell, or alternatively, extend the cell coverage area. RN-served user equipments (relay-UEs) can create severe inter-cell interference in particular when a large number of RNs are deployed in the cell with a reuse factor of power control (PC), it becomes a vital means in the uplink (UL) scheduling and it compensate for channel variations. In LTE network the transmission is of carrier aggregation, coordinated multiple point transmission and reception, and relay. It can be seen as a kind of collaborative communications, in which a relay station (RS) helps to forward user information from neighbouring user equipment (UE)/mobile station (MS) to a local eNode-B (eNB)/base station (BS). Power adaption of high level mobile system is an advance of LTE having multihop routing. In this paper we are going to discuss the relay technique to improve the throughput of the coverage area of base station. When comparing with the WIMAX scheduling our LTE power adaption improve the high data transmission of uplink. (c) 2012 Published by Elsevier Ltd.
