Abstract:
Wireless communications systems and methods related to over-the-air uplink-downlink (UL-DL) reciprocity calibration. A central unit transmits downlink (DL) calibration reference signal (RS) and a calibration request. The central unit receives, in response to the calibration request, a first uplink (UL) calibration RS and a first DL channel estimate associated with a first transmission point (TP) and a first wireless communication device. The central unit transmits a DL coordinated multipoint (CoMP) joint transmission signal according to an uplink-downlink (UL-DL) reciprocity calibration. The UL-DL reciprocity calibration is based on at least a first UL channel estimate based on the first UL calibration RS, the first DL channel estimate, a second UL channel estimate associated with a second TP and the first wireless communication device, and a second DL channel estimate associated with the second TP and the first wireless communication device.

Claim (Index 7):
The method of  claim 4 , further comprising:\n configuring, by the central unit, the first TP to transmit a first DL calibration RS; and configuring, by the central unit, the second TP to transmit a second DL calibration RS, wherein the first DL channel estimate and the third DL channel estimate are based on the first DL calibration RS, and wherein the second DL channel estimate and the fourth DL channel estimate are based on the second DL calibration RS.
