AI summary

Methods, systems, and devices for wireless communication are described. A wireless device may receive, from a network entity, control signaling that indicates a configuration for sensing and reporting information of a target entity in a wireless communication system. The wireless device may obtain geometric information (e.g., shape, dimension, and the like) associated with the target entity in the wireless communication system based on a radio frequency (RF) sensing procedure according to the configuration. The wireless device may transmit, to the network entity, a report including the geometric information associated with the target entity.
