1. A method for wireless communication at a first user equipment (UE), comprising:
transmitting, to a second UE, first control signaling indicating a joint channel estimation procedure for a sidelink connection based at least in part on a set of reference signals from the second UE;
determining a change in one or more channel parameters of the sidelink connection after the first control signaling is transmitted;
transmitting, to the second UE, second control signaling indicating a cancellation of the joint channel estimation procedure for the sidelink connection based at least in part on determining the change in the one or more channel parameters; and
transmitting one or more reference signals of the set of reference signals based at least in part on receiving the second control signaling, at least one reference signal associated with a channel estimation procedure for the sidelink connection.
