Abstract
Feedback information is conveyed between a wireless device and a base station in a cellular communications network via selection and detection of radio resources utilized for an uplink reference signal transmitted from a wireless device to a base station. In this manner, additional feedback information may be sent from the wireless device to the base station without sacrificing any bandwidth available for data transfer between the wireless device and the base station. The radio resources utilized for the uplink reference signal may include cyclic shift and/or time and frequency resources. The uplink reference signal may be an uplink sounding reference signal for a long term evolution network (LTE), or its evolution, such as LTE-Advanced.
