21. A method for wireless communications by a first user equipment (UE), comprising:
transmitting, to a second UE, a set of channel estimation reference signals dedicated for channel estimation of a channel between the first UE and the second UE;
receiving, from the second UE and in response to the set of channel estimation reference signals, a set of quantized samples of the channel for channel estimation, the set of quantized samples based at least in part on the set of channel estimation reference signals; and
transmitting, to the second UE, one or more pre-equalized transmissions that are pre-equalized based at least in part on a pre-equalization matrix, wherein the pre-equalization matrix is based at least in part on receiver-side noise statistics associated with the set of quantized samples of the channel.
