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 22):
The computer-readable medium of  claim 21 , further comprising:\n code for causing the central unit to receive a second UL calibration RS and a second DL channel estimate associated with a second communication link between a second TP and the first wireless communication device when the second communication link satisfies the calibration rule, the second TP being different from the first TP, 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 second DL channel estimate and a second UL channel estimate determined based on the second UL calibration RS.
