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 23):
The computer-readable medium of  claim 21 , further comprising:\n code for causing the central unit to receive a third UL calibration RS and a third DL channel estimate associated with a third communication link between the first TP and a second wireless communication device when the third communication link satisfies the calibration rule, the second wireless communication device being different from the first wireless communication device, wherein the code for causing the central unit to determine the UL-DL reciprocity calibration is further configured to determine the UL-DL reciprocity calibration further based on the third DL channel estimate and a third UL channel estimate determined based on the third UL calibration RS.
