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 1):
A method of wireless communication, comprising:\n transmitting, by a central unit, a calibration rule for determining whether to participate in an uplink-downlink (UL-DL) reciprocity calibration; receiving, by the central unit, a first uplink (UL) calibration reference signal (RS) and a first DL channel estimate associated with a first communication link between a first transmission point (TP) and a first wireless communication device when the first communication link satisfies the calibration rule; determining, by the central unit, the UL-DL reciprocity calibration based on at least the first DL channel estimate and a first UL channel estimate determined based on the first UL calibration RS; and transmitting, by the central unit, a DL coordinated multipoint (CoMP) joint transmission signal according to the UL-DL reciprocity calibration.
