COMMUNICATION METHOD AND DEVICE IMPLEMENTING COMMUNICATION PROCEDURE IN NETWORK WITH EARLY RECEIPT OF INFORMATION ABOUT CHANNEL STATUS Russian patent published in 2023 - IPC H04B7/00 H04W72/02 H04W74/08 

FIELD: communication systems.

SUBSTANCE: communication method performed by the UE during a network communication procedure includes: transmitting a random access preamble; receiving a modified RAR containing an SRS transmission request field, the value of which indicates whether the UE should transmit an SRS. When the value of the SRS transmission request field indicates that the UE should transmit SRS, the SRS is transmitted and one or more subsequent DL transmissions are received with adaptive spatial signal processing performed based on the CSI obtained from the SRS measurements.

EFFECT: implementation of a communication procedure in a network with early receipt of information about the state of the channel, which makes it possible to implement hybrid analogue and digital beamforming and spatial multiplexing.
