Abstract	Relaying concept has been proposed to satisfy the demanding requirements of LTE-Advanced which was recently agreed by 3GPP as an evolution of LTE. Relay enhanced networks are expected to enhance the coverage and capacity in a cost efficient way. Yet, transmit power of UE should be optimized in a relay based scenario where interference increases by additional RNs. New cell edges introduced by RNs increase the number of users that transmit with high power. This leads to severe interference, in particular when a large number of RNs are deployed in a cell with reuse one. In this paper, performance evaluation of relay based deployment within the LTE-Advanced uplink framework is carried out by applying the standardized LTE power control scheme both at eNBs and RNs. The importance of power control parameter settings is examined to achieve optimal performance in relay scenarios.
