  Abstract

This paper suggests the methods to improve the wireless backhaul link of the Relay FDD mode that 3GPP LTE-Advanced supports. New RRC message and Relay startsup procedure are introduced to apply Carrier Aggregation in the Relay wireless backhaul. Also, we design new reference signal that makes Type 1 Relay operated in full-duplexing, expecting to maximize the radio resource utilization. And, we propose the efficient configuration for the periodic uplink control information under the backhaul subframe allocation method in LTE-Advanced Relay. Hereafter, the standard activities in the 3GPP RAN is supposed to focus on the improvement of the LTE-Advanced features. Therefore, the suggestions in this paper are expected to be actively discussed in the LTE-Advanced future releases.
