Abstract: Aspects presented may enable RF sensing to be adaptive to the environment to improve the sensing, performance, and/or the spectrum efficiency of cellular systems and the power efficiency of RF sensing nodes. In one aspect, an RF sensing node extracts one or more features for a set of objects of an area via at least one non-RF sensor. The RF sensing node transmits, to a network entity, the one or more features or at least one non-RF measurement derived from the one or more features. The RF sensing node receives, from the network entity, an RRS transmission configuration derived based on the one or more features or the at least one non-RF measurement transmitted to the network entity.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a sidelink device may receive a configuration indicating one or more sidelink resource pools. The sidelink device may receive a request to report a radio frequency (RF) capability. The sidelink device may transmit, responsive to the request, an RF capability type of the sidelink device. The sidelink device may receive a sidelink allocation indicating a set of sidelink resources from the one or more sidelink resource pools and indicating one or more sidelink communication resources, one or more sidelink sensing resources, or both associated with the set of sidelink resources. In an aspect, the sidelink allocation may be based on the RF capability type of the sidelink device.

Abstract: Radio frequency (RF) sensing of a target object by a wireless network is supported by a network node that derives one or more object features for the target object using non-RF sensor measurements and reports the object features to a server for the RF sensing. The non-RF sensors, for example, may be one or more of a camera, ultra-sound sensor, lidar, barometer, etc. The object features for the target object, which may be related to the object size, position, motion, etc. may be separately reported for each non-RF technology or may be reported as a common set of object features. The object feature report may include a time stamp, and may associate an object ID for the target object with the reported object features. Some object features may be prioritized over others, and object features that do not change may not be reported in subsequent reports.

Abstract: Disclosed are techniques for sensing. In an aspect, a wireless node receives or determines a time-division duplex (TDD) configuration that configures a set of contiguous downlink symbols, a set of contiguous uplink symbols and a set of contiguous cell-specific flexible symbols that follows the set of contiguous downlink symbols and precedes the set of contiguous uplink symbols. The wireless node further performs a radio frequency for sensing (RF-S) operation during one or more flexible symbols of the set of contiguous cell-specific flexible symbols.

Abstract: Techniques are provided for mitigating group delay errors across half duplex and full duplex operations. An example method of performing a round trip time message exchange includes performing the round trip time message exchange with a wireless node including receiving a downlink positioning reference signal and transmitting an uplink positioning reference signal, wherein the round trip time message exchange is associated with at least one duplex mode, and reporting a receive-transmit time difference measurement value based on the round trip time message exchange, wherein the reporting includes an indication of the at least one duplex mode.

Abstract: A positioning reference signal measurement method includes: receiving, at a user equipment from a network entity, an OFDM PRS (orthogonal frequency division multiplexing positioning reference signal) comprising a first set of first OFDM symbols that are consecutive and include a first center symbol and at least one pair of first side symbols disposed symmetrically about the first center symbol and having identical resource element sounding patterns; combining the first side symbols in each of the at least one pair of first side symbols to produce at least one first combined symbol; and determining a measurement of the OFDM PRS based on the at least one first combined symbol and the first center symbol.

Abstract: A technique is performed at a user equipment (UE) for supporting one or more radio frequency (RF) sensing measurements. A reflected downlink signal is received, wherein the reflected downlink signal is transmitted as a downlink signal from a base station and reflected off of a target. An uplink signal is transmitted to be reflected off of the target and received by the base station as a reflected uplink signal. A UE receive-transmit (RX-TX) time difference is determined, representing a difference between a time at which the reflected downlink signal is received by the UE and a time at which the uplink signal is transmitted by the UE. A UE measured frequency offset is determined based on reception of the reflected downlink signal, the UE measured frequency offset comprising a Doppler shift component corresponding to a velocity of the target.
