APPARATUS AND METHOD FOR INTERLEAVING DATA IN A RELAY PHYSICAL DOWNLINK CONTROL CHANNEL(R-PDCCH)

摘要

PURPOSE: A device for interleaving data in a relay physical downlink control channel is provided to solve delay problems and overhead in a backhaul link between a relay terminal and a base station by mapping the interleaved data in a transmission resource. CONSTITUTION: A plurality of relay terminals provides two-way communication between a first base station and a plurality of mobile terminals. The first base station transmits an R-PDCCH(Relay-Physical Downlink Control CHannel) from a downlink to a plurality of relay terminals. The R-PDCCH includes a second search space including uplink grants related a plurality of the relay terminals and a first search space including downlink grants related to the plurality of the terminals.
