APPARATUS AND METHOD FOR PREVENTING COMMUNICATION PERFORMANCE DETERIORATION DUE TO REPEATER DELAY IN OFDM/OFDMA WIRELESS COMMUNICATION SYSTEM

摘要

An apparatus and method for preventing the deterioration of communication performance by the repeater delay in a mobile communication system of the OFDM / OFDMA scheme is disclosed. A base station communicating with the terminal according to a radio protocol in a mobile communication system is a OFDM / OFDMA scheme in the OFDM / OFDMA scheme in accordance with the present invention; A repeater for repeating does not belong to the coverage of the base station amplifies the signal between the terminal and the base station in a difficult position to the signal from the base station directly received; And a delay device for delaying the signals transmitted through the repeater in at least one OFDM symbol time. According to the present invention, the deterioration of the communication performance of the terminal in the base station and repeater coverage of the border area, which may be caused by the additional delay caused by the use of repeaters can be prevented.
