Triggered sidelink quasi-colocation parameter update

A method of wireless communication performed by a base station, comprising:

• detecting that a trigger condition is satisfied based at least in part on a motion sensor signal of a user equipment (UE);
• and
• triggering or transmitting an update to a parameter for sidelink beam management based at least in part on the trigger condition being satisfied, wherein the UE is:
• a transmitter of a synchronization signal used for the sidelink beam management, or
• a receiver of the synchronization signal used for the sidelink beam management.

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• detect that a trigger condition is satisfied based at least in part on a motion sensor signal of the UE;
• and
• trigger or transmit an update to a parameter for sidelink beam management based at least in part on the trigger condition being satisfied, wherein the UE is:
• a transmitter of a synchronization signal used for the sidelink beam management, or
• a receiver of the synchronization signal transmitted by another UE used for the sidelink beam management.
