Techniques for signaling reference signal parameters in a wireless communication system

Abstract

A technique for operating a wireless communication device includes assigning a reference signal bandwidth to a reference signal. Cyclic shift control bits (associated with the reference signal) are then allocated based on the assigned reference signal bandwidth. The allocated cyclic shift control bits specify a cyclic shift associated with the reference signal.
