1. A method of wireless communication by a second user equipment (UE), the method comprising:
receiving, from a first UE, a first signal in a burst of a first plurality of reference signals transmissions, wherein each of the burst of the first plurality of reference signals transmissions is transmitted via a first initial transmit beam according to a first time offset and a first periodic interval;
selecting, after receiving the burst of the first plurality of reference signals and based on the burst of the first plurality of reference signals, a receive beam for reception of data from the first UE on a sidelink between the second UE and the first UE;
selecting a second initial transmit beam corresponding to the receive beam; and
transmitting, to the first UE, a second signal in a burst of a second plurality of reference signals transmissions via the second initial transmit beam according to a second time offset and a second periodic interval, wherein the second signal is configured to provide the first UE with a basis for selecting a third beam for receiving data from the second UE on the sidelink.
