A base station includes a transmit path circuitry that determines a PUCCH format 3 index and transmits an uplink grant to a subscriber station, the uplink grant including an indication of the PUCCH format 3 index. The base station also includes a receive path circuitry that receives a PUCCH format 3 signal in a subframe from the subscriber station. The receive path circuitry also receives a first demodulation reference signal for the PUCCH format signal in the first slot of the subframe, where the first demodulation reference signal is determined based at least partly upon a first demodulation reference signal cyclic shift number. The receive path circuitry also receives a second demodulation reference signal for the PUCCH format 3 signal in the second slot of the subframe, where the second demodulation reference signal is determined based at least partly upon a second demodulation reference signal cyclic shift number. |
