Abstract: Techniques are provided for positioning of user equipment (UE) with paging messages. An example method for positioning a user equipment with paging messages includes receiving a positioning paging message with a user equipment in an idle state, measuring positioning measurements in response to receiving the positioning paging message, determining location information based at least in part on the positioning measurements, and transmitting the location information via a random access procedure.

Abstract: A mobile device can report its capabilities to a network node regarding one or more phase characteristics between Sounding Resource Signal (SRS) resources transmitted by the mobile device under one or more circumstances, enabling the network to configure the mobile device accordingly. Such reporting can enable the network to coherently process multiple SRS resources, effectively increasing the bandwidth of the SRS resources and, ultimately, the accuracy of a position determination for the mobile device. Various techniques are provided for reporting capabilities and determining applicable conditions.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a target UE receives zone information associated with a set of zones, the zone information indicating, for each of a plurality of candidate UEs for a sidelink-assisted position estimation procedure of the target UE, a zone identifier of a zone in which the respective candidate UE is located. The target UE selects one or more candidate UEs for the sidelink-assisted position estimation procedure based at least in part upon the zone information. The target UE performs the sidelink-assisted position estimation procedure with at least the selected one or more candidate UEs.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

Abstract: Various procedures associated with autonomous uplink (AUL) are disclosed. In order to address the mismatch between listen before talk (LBT) and AUL bandwidth a fractional sensing channel is defined less than 20 MHz. Accordingly, a user equipment (UE) may use the fractional sensing channel to perform LBT only on the resources allocated for AUL. Contention window update may further be modified for transmissions spanning multiple transmission opportunities (TxOPs). A contention window update may occur over all transmission channels considering full acknowledgement information of each TxOP, a percentage of acknowledgement information weighted on the number of channels, a percentage of acknowledgement information weighted on the ratio of resources on each channel, or by selecting a primary channel of the multiple channels for the contention window update. In repetition scenarios, the reference transmission for contention window updates may be selected depending on whether all repetitions are within one or multiple TxOPs.

Abstract: Certain aspects of the present disclosure provide techniques for adaptive node activation and configuration in cooperative sensing. A method that may be performed by a sensing management function (SnMF) entity includes receiving a first radio frequency (RF) sensing request, from a first entity, for scanning an environment to detect at least a first object, initiating a first RF sensing session in the environment in response to the first RF sensing request, receiving a second RF sensing request, from a second entity, for scanning the environment to detect at least a second object during the first RF sensing session, accommodating the second RF sensing request using output from the first RF sensing session, wherein the first RF sensing session is ongoing, detecting the first and second objects in the environment, and transmitting information about the detected first and second object to the first and second entity, respectively.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may determine a plurality of measurement gap (MG) configurations, each MG configuration defining one or more MGs. The UE may send, to a serving base station, a request to use a first MG configuration from the plurality of MG configurations, and may receive a response to the first request. The UE then measures positioning signals using an MG configuration indicated by the response. Based on measurements of the first set of positioning signals, the UE may select a second MG configuration, send a second request to use the second MG configuration, and receive a response to the second request. The UE then measures a second set of positioning signals using an MG configuration indicated by the response to the second request.

Abstract: Techniques providing opportunistic frequency switching for frame based equipment (FBE), such as may be configured to minimize opportunistic frequency switching delay in FBE new radio (NR) unlicensed (NR-U) networks and/or to provide frequency diversity FBE access based on offset sequences of medium sensing occasions for the carrier frequencies are disclosed. Within the FBE mode network, a base station may configure a pattern of sensing locations in each frame for each frequency transmission unit of the plurality of frequency transmission units, wherein an inter-unit delay of sensing locations between a first frequency transmission unit and a next adjacent frequency transmission unit and between a last frequency transmission unit and the first frequency transmission unit is a fixed duration. Opportunistic frequency switching of embodiments may utilize the medium sensing locations for opportunistically switching between a sequence of the frequency transmission units for implementing frequency diversity FBE access.

Abstract: In an aspect, a BS transmits PRS on a first frequency-domain resource during a measurement period. A UE measures the PRS, and transmits a RS-P (e.g., SRS-P) on a second frequency-domain resource that does not overlap with the first frequency-domain resource in frequency.
