DATA-RECEIVING METHOD AND APPARATUS FOR RELAY STATION IN WIRELESS COMMUNICATION SYSTEM

摘要

The data-receiving method for a relay station in a wireless communication system comprises the steps of: receiving wireless resource allocation information from a base station via a relay physical downlink control channel (R-PDCCH); and receiving data from the base station via a relay physical downlink shared channel (R-PDSCH) indicated by the wireless resource allocation information, wherein said wireless resource allocation information contains allocation information of a resource block in a frequency domain and allocation information of an OFDM symbol in a time domain. The method of the present invention provides wireless resource allocation information which indicates the time relationship between the control channel through which the base station transmits information to user equipment and the control channel through which the relay station transmits information to the user equipment connected to the relay station, thus enabling the relay station to reliably receive the signal transmitted from the base station in a backhaul link between the base station and the relay station in the wireless communication system containing the relay station.
