Abstract:
The present disclosure describes over-the-air UL-DL reciprocity calibration of UEs. In some embodiments, the UE may perform the calibration at the UE, while in other embodiments the BS may determine the calibration parameters for a UE and send the parameters to the UE for implementation. The BS may explicitly or implicitly transmit an UL channel estimate to the UE for use with the DL channel estimate. The UE determine calibration parameters to implement at the UE based on the BS feedback. Alternatively, the BS may transmit UE calibration parameters determined as a byproduct if the BS's own calibration procedure. The UE may instead participate in a calibration procedure with another UE. Under any approach, the UE may implement in its RF chain the results of the calibration procedure.

Claim (Index 9):
A method of wireless communication, comprising:\n receiving, by a base station, an uplink (UL) calibration reference signal (RS) and a calibration request from a user equipment (UE); determining, by the base station, an UL channel estimate of an UL channel associated with the UE and the base station based on the UL calibration RS; and transmitting, by the base station to the UE in response to the calibration request, a downlink (DL) calibration RS and the UL channel estimate for use by the UE in calibrating one or more parameters of the UE.
