Method and apparatus for transmitting control information from relay node on backhaul uplink

A relay node for transmitting uplink control information, the relay node comprising:

• a receiving module for receiving downlink control information and data from a base station;
• a transmitting module for transmitting the uplink control information and data to the base station;
• a plurality of antennas connected with the transmitting module;
• and
• a processor connected with the receiving module and transmitting module, the processor controlling the relay node including the receiving module and the transmitting module,
• wherein the processor is configured to:
• receive, using the receiving module, a downlink data;
• and
• transmit, using the transmitting module, 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 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.
