METHOD AND SYSTEM FOR MULTIPLEXING ACKNOWLEDGEMENT SIGNALS AND SOUNDING REFERENCE SIGNALS Russian patent published in 2015 - IPC H04L27/26 H04B7/26 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to wireless communication. A base station includes a transmission 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 receiving path circuitry that receives a PUCCH format 3 signal in a subframe from the subscriber station. The receiving 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 on a first demodulation reference signal cyclic shift number. The receiving 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 on a second demodulation reference signal cyclic shift number.

EFFECT: communication efficiency when multiplexing acknowledgement signals and sounding reference signals.
