METHOD FOR ALLOCATING UPLINK ACK/NACK CHANNELS

摘要

PURPOSE: An uplink ACK/NACK channel allocating method is provided to obtain indexes of ACK/NACK channels through CCE indexes of downlink control channels. CONSTITUTION: Node B transmits a downlink physical control channel and downlink data(701). A terminal detects the downlink physical control channel. The terminal receives downlink data that node B transmits. The terminal obtains indexes of ACK/NACK channels of an uplink sub frame based on an minimum CCE index of the downlink physical control channel.
