Sidelink beam managment with transmitter rotation

A baseband processor, configured to:

• receive a first beam tracking reference signal from a receiving (RX) UE;
• cause transmission of sidelink transmissions using an initial TX beam that corresponds to an optimal RX beam for receiving the first beam tracking reference signal;
• transmit a second beam tracking reference signal using the initial TX beam;
• receive a third beam tracking reference signal from the RX UE;
• and
• cause transmission of sidelink transmissions using a revised TX beam that corresponds to an optimal RX beam for receiving the third beam tracking reference signal.

A method for a user equipment (UE), comprising:

• transmitting reference signals to a receiving (RX) UE using different transmit (TX) beams;
• receiving a signal indicative of an initial TX beam from the RX UE;
• detecting degradation of a link associated with the initial TX beam;
• and
• in response, selecting a revised TX beam for transmitting subsequent sidelink transmissions to the RX UE.
