1. A method for wireless communication at a user equipment (UE), comprising:
transmitting, to a network device, an indication of a detected presence of an interfering neighboring node, the indication based at least in part on a measurement of the interfering neighboring node;
receiving, from the network device, configuration information for a silencing signal associated with the UE, wherein the configuration information is based at least in part on the indication;
receiving, from the network device, a first portion of a downlink communication via a shared radio frequency spectrum band;
transmitting, subsequent to receiving the first portion of the downlink communication, a first instance of the silencing signal via the shared radio frequency spectrum band based at least in part on the configuration information and the indication of the detected presence of the interfering neighboring node; and
receiving, subsequent to transmitting the first instance of the silencing signal, one or more remaining portions of the downlink communication via the shared radio frequency spectrum band.
