METHOD FOR CONTROLLING TRANSMISSION POWER WITH EMULATION OF PROPAGATION OF REFERENCE SIGNAL USED TO ESTIMATE LOSSES OVER CHANNEL WITH PRE-CODING, DEVICE IMPLEMENTING ITS AND THEIR VARIANTS Russian patent published in 2024 - IPC H04W52/24 

FIELD: wireless communication.

SUBSTANCE: mentioned technical result is achieved by receiving a channel state information reference signal (CSI-RS), transmitted from the digital ports of the transmitting and receiving antenna unit of the transmitting and receiving point for user equipment located in the served cell; measuring the channel from the digital ports of the transmitting and receiving antenna unit of the transmitting and receiving point based on the mentioned CSI-RS; obtaining a direct indication or approximation of the precoding to be applied by the transceiver point for communication with the user equipment (UE); based on emulating the propagation of a reference signal from a transceiver point (TRP) to the UE over an equivalent channel obtained by applying the obtained precoding or precoding approximation to the measured channel, an RSRP estimate is calculated (S130); determining a PL value based at least in part on the RSRP estimate; and performing uplink transmission on the TRP with the transmit power adjusted based at least in part on the determined PL value.

EFFECT: improving the accuracy of estimating the reference signal receive power (RSRP), determining the propagation loss (PL), and performing power control (PC) without increasing overhead.
