CONTROL SIGNAL TRANSMITTING METHOD AND APPARATUS IN RELAY STATION

摘要

A method for transmitting a control signal in a relay station comprises: in a 1st subframe, receiving a control signal and data from a base station; and in a 2nd subframe, transmitting to the base station an ACK/NACK (acknowledgement / negative acknowledgement) signal for the data, wherein a radio resource for transmitting the ACK/NACK signal is determined by a radio resource to which the control signal received in the 1st subframe is allocated, and by a local PUCCH (physical uplink control channel) index value received for an upper layer signal.
