Sidelink transmission and reception beams for beam management

One or more processors of a receiver (Rx) user equipment (UE) that communicates with one or more transmitter (Tx) UEs on a sidelink interface via one or more Rx beams, the one or more processors configured to perform operations comprising:

• determining a reception operation to be performed by the Rx UE in a slot;
• selecting, based on the reception operation, at least one Rx beam with which to perform the reception operation in the slot;
• and
• performing the reception operation in the slot using the at least one Rx beam.

A method comprising:

• receiving, from a receiver (Rx) user equipment (UE) via a sidelink interface, a beam switching time of the Rx UE;
• configuring one or more resources for transmitting one or more sidelink channel state information reference signals (CSI-RS) to the Rx UE, wherein a maximum number of sidelink CSI-RS symbols for transmission in a slot is determined based on the beam switching time of the Rx UE;
• and
• causing transmission to the Rx UE:
• of (i) an indication of a selected number of sidelink CSI-RS symbols in the slot, wherein the selected number of sidelink CSI-RS symbols is less than or equal to the maximum number of sidelink CSI-RS symbols, and (ii) the one or more sidelink CSI-RS using the one or more resources.
