UPLINK CHANNEL PRELIMINARY CODING METHOD, DEVICE AND SYSTEM Russian patent published in 2020 - IPC H04W72/12 H04W48/12 

FIELD: physics.

SUBSTANCE: invention relates to wireless network technology and more specifically to a method of uplink channel precoding. Disclosed is an uplink channel precoding method, a device and a system. Terminal device transmits the probing reference signal (SRS) in at least one SRS signal resource and receives downlink control information (DCI) used by the network device for dispatching uplink data transmission, wherein the DCI information comprises a rank indicator (RI) and/or a signal resource indicator SRS (SRI), then determines a precoding scheme for the uplink data according to the RI indicator and/or the SRI indicator and the at least one SRS signal resource, pre-encodes uplink data according to said precoding scheme and transmits pre-coded uplink data.

EFFECT: technical result is reduction of non-productive consumption of signal resources.
