Uplink multiple-input multiple-output (mimo) scheduling using beamformed reference signals

A method for wireless communications by a transmit receive point (TRP), comprising:

• receiving, from a wireless node, a beamformed reference signal;
• determining, based on the beamformed reference signal, one or more parameters for the wireless node to use for adjusting subsequent beamformed transmissions;
• and
• signaling the parameters to the wireless node.

An apparatus for wireless communications, comprising:

• a processor configured to:
• identify one or more parameters for beamformed transmission to a transmit receive point (TRP),
• transmit a reference signal using beamforming in accordance with the identified parameters, and
• receive, from the TRP in response to the reference signal, signaling for adjusting the one or more parameters for one or more subsequent beamformed transmissions;
• and
• a memory coupled to the processor.
