Patent ID: 8780784

Claim:
A method for transmitting uplink control information by a relay node, the method comprising: receiving, at the relay node from a base station, a downlink data; and transmitting, from the relay node to the base station, a hybrid automatic repeat request (HARQ)-acknowledgment for the downlink data using a physical uplink control channel (PUCCH), wherein an allocated PUCCH resource used by the relay node to transmit the HARQ-acknowledgment to the base station is configured by a higher layer signaling, wherein the relay node is configured with a plurality of antennas, and uses separate PUCCH resources allocated to each of the antennas, wherein the HARQ-acknowledgment is transmitted on the plurality of antennas, and wherein the PUCCH resource for each of the plurality of the antennas is configured by the higher layer signaling.
