Abstract:
1. A method of configuring relay link resources, comprising: receiving, by a relay node (RN), relay link information on the relay link resources, from a base station, wherein the relay link resources start from an orthogonal frequency division multiplexing (OFDM) symbol corresponding to a start time of the RN receiving the relay link information, the OFDM symbol corresponding to the start time of the RN receiving the relay link information is a Kth OFDM symbol in a base station subframe, the relay link resources comprise f OFDM symbols, wherein f=14−K−N, wherein K is a serial number of one of the OFDM symbols comprised in the base station subframe corresponding to a start time of the base station which sends the relay link information, wherein N is an integer and is one of 0, 1 and 2, and a sum of K and N is smaller than 14; wherein the relay link resources are configured according to an OFDM symbol number used by a physical downlink control channel (PDCCH) of a multimedia multicast broadcast single frequency network (MBSFN) subframe where a relay link of the RN is located, an offset, and a length of a PDCCH in the base station subframe, and the offset is a time offset of timing of an access link of an RN frame relative to timing of a relay link of the RN frame.
