Methods, systems, and devices for wireless communications are described for receiver-assisted channel access in shared radio frequency spectrum. A receiver, such as a user equipment (UE) may transmit a measurement report to a transmitter, such as an access network entity, that indicates channel occupancy as measured at the receiver. In some cases, the receiver may identify resources for signal measurement and reporting that are configured by the transmitter, and provide an interference measurement report based on the signal measurements. The interference measurement report may indicate whether a channel is occupied, or an occupancy level of the channel. Resources may be configured for multiple beams, with the interference measurement report including interference measurements for the multiple beams. Further, the signal resources may provide resources for a listen-before-talk (LBT) procedure, through signal resource sets that span multiple slots.
