US 8,797,941 B2 · Relay node device for receiving control information from a base station and method therefor

Abstract

The present invention relates to a relay node device for receiving control information from a base station and a method therefor. The relay node device according to the present invention comprises: a receiver, which receives information about an area where a relay-physical downlink control channel (R-PDCCH), the channel for transmitting control information for the relay node from a base station, is allocated; a processor, which searches for at least one R-PDCCH for the relay node based on the R-PDCCH allocation information received; and an R-PDCCH receiver, which receives the at least one R-PDCCH from the fourth symbol of the first slot in a downlink backhaul subframe of the area where the at least one R-PDCCH searched for by the processor has been allocated.

Dependent claims

A method of receiving signals by a relay node (RN) from an eNode B (eNB), the method comprising:

receiving information on resource assignment configured for at least one R-PDCCH (relay-physical downlink control channel) transmission from the eNB;
monitoring at least one at least one R-PDCCH based on the information on the resource assignment;
receiving a first R-PDCCH including downlink (DL) grant through four symbols of a first slot in a subframe for the eNB-to-the RN transmission from the eNB;
receiving a second R-PDCCH including an uplink (UL) grant through a second slot of the subframe from the eNB;
and
receiving data channel associated with the first R-PDCCH through the second slot of the subframe from the eNB.
