1. An apparatus for wireless communication at a receiving user equipment (UE), comprising:
one or more memories storing processor-readable code; and
one or more processors, coupled with the one or more memories, at least one of the one or more processors operable to cause the receiving UE to:
receive, from a transmitting UE, a sidelink reference signal in a first symbol of a slot; and
perform, in accordance with the sidelink reference signal received in the first symbol of the slot, a joint channel estimation using a first portion of the first symbol and an automatic gain control (AGC) training using a second portion of the first symbol, wherein the AGC training occurs within a cyclic prefix duration or within an extended cyclic prefix associated with the second portion of the first symbol.
