Abstract
Systems and methodologies are described that facilitate configuring a sounding reference signal transmission in a wireless communication environment. A UE can employ coordinated multi-point transmission and/or reception such that multiple cells collaborate to transmit data to the UE and/or receive data from the UE. To support the coordinated multi-point transmission and/or reception, the UE can transmit a sounding reference signal that is configured to enable reliable reception of the sounding reference signal by members of a cooperating set. In addition, configuration of the sounding reference signal can be coordinated to enable more efficient transmission and utilization of the sounding reference signal. Configuration of the sounding reference signal can be based upon information exchanged between the multiple cells. Moreover, the multiple cells can coordinate to set and control a transmit power of the sounding reference signal.
