Document Type and Number:
WIPO Patent Application WO/2011/132945
Kind Code:
A2
Abstract:
A method for transmitting a relay node specific downlink physical control channel (R-PDCCH) at a base station in a wireless communication system is disclosed. More specifically, the method includes the steps of allocating one or more Resource Blocks (RBs) for the relay node specific downlink physical control channel, mapping the relay node specific downlink physical control channel to the one or more resource blocks, and transmitting the relay node specific downlink physical control channel to the relay node by using the one or more resource blocks, wherein the mapping step includes mapping the relay node specific downlink physical control channel along a frequency direction in a symbol belonging to a lowermost index, among the one or more resource blocks, and then mapping the relay node specific downlink physical control channel along the frequency direction in a symbol belonging to a next index.
