Abstract
In an aspect, a UE obtains assistance data based on a set of clutter measurements associated with a plurality of network nodes, updates an RF sensing session based on the assistance data, and performs a set of measurements based on the updated RF sensing session. In another aspect, a network entity provides a first indication of a signaling scheme for a set of clutter measurements associated with a plurality of network nodes, receives, based on the signaling scheme, a second indication of the set of the clutter measurements from the plurality of network nodes, and provides, for a UE, assistance data based on the set of clutter measurements.
Claims27
An apparatus of wireless communication at a user equipment (UE), 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:
- obtain assistance data based on a set of clutter measurements associated with a plurality of network nodes;
- update a radio frequency (RF) sensing session based on the assistance data;
- receive pattern information for at least one transmit beam of a network node;
- and
- selectively perform at least one measurement of a set of measurements of a sensing reference signal associated with the at least one transmit beam based on the updated RF sensing session and the pattern information.
An apparatus of wireless communication at a network entity, 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:
- provide a first indication of a signaling scheme for a set of clutter measurements associated with a plurality of network nodes;
- receive, based on the signaling scheme, a first subset of the set of the clutter measurements from the plurality of network nodes, wherein the first subset comprises a set of absolute clutter measurements of the set of clutter measurements, wherein the set of absolute clutter measurements has a first periodicity;
- receive a second subset of the set of clutter measurements, wherein the second subset comprises a set of differential clutter measurements of the set of clutter measurements, wherein the set of differential clutter measurements has a second periodicity that is shorter than the first periodicity;
- and
- provide, for a user equipment (UE), assistance data based on the set of clutter measurements.
