Abstract

A user equipment (UE) may receive at least one of a sensing signal for an object associated with the UE or of a channel state information (CSI) reference signal (CSI-RS) from a network node. The UE may transmit an indication of a broken association with the object based on at least one of the sensing signal or the CSI-RS. The UE may measure a strength of at least one of the sensing signal or the CSI-RS. The UE may measure at least one of a reference signal receive power (RSRP) or a relative RSRP backoff associated with at least one of the sensing signal or the CSI-RS. The UE may transmit the indication of the broken association in response to the measured strength of at least one of the sensing signal or the CSI-RS being less than or equal to a signal strength threshold value.
