Patent ID: 8467432

Claim:
A base station apparatus, comprising: a transmitter configured to transmit, to a plurality of mobile stations, control information on a control channel element (CCE), wherein the CCE is associated with a physical uplink control channel (PUCCH) and the PUCCH is determinative of a cyclic shift value among a plurality of cyclic shift values comprising a set of channel quality indicator (CQI) cyclic shift values and a set of acknowledgement/negative acknowledgement (ACK/NACK) cyclic shift values, with one or more unused cyclic shift values separating the sets of CQI cyclic shift values and ACK/NACK cyclic shift values; and a receiver configured to receive: CQI signals transmitted by one or more mobile stations of the plurality using respective CQI cyclic shift values of the set of CQI cyclic shift values; and ACK/NACK signals transmitted by one or more mobile stations of the plurality using respective ACK/NACK cyclic shift values of the set of ACK/NACK cyclic shift values.
