Abstract: In some implementations, an ultra-wideband (UWB) management server may send a first message to a UWB anchor, wherein: the first message is indicative of a first threshold to use in a UWB positioning session, the first threshold specifying at least one trigger condition for making available one or more reserved time slots in a Contention Access Period (CAP) of the UWB positioning session. The UWB management server may determine a second threshold for identifying a UWB responder having a respective reserved time slot in the CAP. The UWB management server may send a second message to the UWB anchor, wherein the second message causes the UWB anchor to either: (i) move the respective reserved time slot in the CAP for the UWB responder to a respective one or more time slots in a Contention Free Period (CFP), or (ii) terminate the UWB positioning session with the UWB responder.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive at least one communication of a plurality of communications associated with at least one physical layer channel, wherein a first set of the plurality of communications includes the at least one communication and is secured by a first security key, and a second set of the plurality of communications is secured by a second security key. The network node may decrypt the at least one communication based at least in part on the first security key, wherein the first security key is based at least in part on a first set of physical layer parameter values and the second security key is based at least in part on a second set of physical layer parameter values. Numerous other aspects are described.

Abstract: Aspects presented herein may improve the efficiency and accuracy of ranging operations, such as ranging operations based on ultra-wideband or sidelink. In one aspect, a first wireless device receives a response message from at least one second wireless device, the response message including a clock accuracy value of the at least one second wireless device, a location confidence value of the at least one second wireless device, or a combination thereof. The first wireless device establishes a ranging session with the at least one second wireless device based on the clock accuracy value of the at least one second wireless device exceeding a clock accuracy threshold, or the location confidence value of the at least one second wireless device exceeding a location confidence threshold, or both.

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: In some implementations, a first UE may receive an indication of the positioning session in which the first UE is to participate, wherein the first UE is to participate by sending and/or receiving SL-PRS via an SL communication link with a second UE. The first UE may obtain, with the first UE, the SL PRS DRX configuration for the positioning session, wherein: the SL PRS DRX configuration for the positioning session designates a plurality of DRX cycles during the positioning session, each DRX cycle having a respective ON duration and a respective OFF duration. The first UE may monitor the SL communication link for the positioning information with the first UE in accordance with the SL PRS DRX configuration.

Abstract: The reduction of a timing collision between the Sounding Reference Signal (SRS) instances when a user equipment (UE) is in a Radio Resource Control (RRC) inactive state and SRS is configured to use an uplink (UL) bandwidth part (BWP) different than a UL BWP of messages transmitted by the UE in the RRC inactive state. More particularly, embodiments may implement collision-reduction techniques and establish action times for canceling the transmission of one or more SRS instances.
