Disclosed embodiments may include an apparatus having one or more processors coupled to one or more computer-readable storage media. The one or more processors may be configured to transmit and/or receive channel state information reference signal (CSI-RS) resource configuration information, demodulation reference signals (DM-RS), uplink sounding reference signals (SRS), and power control parameters to support uplink coordinated multi-point (CoMP) operations. Other embodiments may be disclosed.
