Abstract
Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a wireless device or a server. The apparatus may receive, from a network entity, an indication of clutter information from at least one sensing node or at least one sensor, where the clutter information is associated with one or more stationary or slow-moving reflections of one or more signals with respect to the at least one sensing node or the at least one sensor. The apparatus may also configure at least one filter in a set of filters at the wireless device based on the clutter information from the at least one sensing node or the at least one sensor.
Claims27
An apparatus for wireless communication at a wireless device, comprising:
- memory;
- and
- at least one processor coupled to the memory and, based at least in part on information stored in the memory, the at least one processor is configured to:
- receive, from a network entity, an indication of clutter information from at least one sensing node or at least one sensor, wherein the clutter information is associated with one or more stationary or slow-moving reflections of one or more signals with respect to the at least one sensing node or the at least one sensor;
- configure at least one filter in a set of filters at the wireless device based on the received clutter information from the at least one sensing node or the at least one sensor, wherein the indication of the clutter information comprises assistance data associated with the at least one filter of the wireless device;
- perform a radio frequency (RF) sensing measurement for the configured at least one filter of the wireless device;
- and
- transmit, for the network entity, an indication of the RF sensing measurement for the configured at least one filter of the wireless device.
