Abstract: Aspects presented herein may improve the performance and accuracy of RF-based positioning. Aspects presented herein may enable a device to use RF Doppler measurements to detect and mitigate multipath effects in RF-based positioning. The RF-based positioning may include satellite navigation, terrestrial positioning system, and/or indoor positioning. In one aspect, a UE receives, via a receiver, signals from one or more entities. The UE determines whether each received signal is a multipath signal based on a Doppler shift measurement. The UE de-weights or excludes one or more signals of the received signals in estimating a position of the UE based on whether the respective received signal is determined to be a multipath signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a failure event for a beam or a link, between the UE and a base station, is occurring or will occur, and transmit a message to the base station indicating that the UE is refraining from performing a recovery procedure for the beam or a link for a time duration. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position determination entity (PDE) receives a request to schedule an on-demand PRS positioning session of a UE at a future time, wherein the request is configured to request a first set of parameters for the scheduled on-demand PRS positioning session, with an availability of one or more parameters of the first set of parameters at the future time being indeterminable when the request is received. PDE determines the availability of the one or more parameters at the future time. PDE determines a PRS configuration for the scheduled on-demand PRS positioning session in advance of the future time.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity configures a sidelink anchor group with sidelink anchor(s), to which respective sidelink PRS pre-configuration(s) are sent. A UE transmits a request to schedule an on-demand sidelink PRS position estimation session of the UE. The position estimation entity provides the UE with assistance data associated with the sidelink anchor group for the on-demand sidelink PRS position estimation session. The UE sends the sidelink anchor group a sidelink PRS trigger to perform a sidelink PRS exchange with some or all of the sidelink anchor group in accordance with the respective sidelink PRS pre-configuration(s).

Abstract: Disclosed are systems and techniques for wireless communications. For example, a process can include determining a subset of radio frequency (RF) sensing devices from a plurality of available RF sensing devices for performing an RF sensing technique for a target object. The subset of RF sensing devices may be determined based on a plurality of factors associated with the plurality of available RF sensing devices. The process can include transmitting, to at least one RF sensing device of the subset of RF sensing devices, at least one message instructing the subset of RF sensing devices to perform the RF sensing technique for the target object to obtain one or more characteristics of the target object.

Abstract: Techniques are provided in which a target UE can be provided with a processing window (PW) configuration that defines a PW during which the target UE may measure one or more RS resources. The PW optionally may allow the target UE to transmit an uplink (UL) RS. The PW configuration may be provided to the target UE by a serving base station of the target UE in response to a request for the PW configuration by the target UE or a location server. The request may include information regarding an RS configuration provided to the target UE.

Abstract: The positions of multiple user equipments (UEs) are jointly determined by a location server using positioning measurements from a comment set of positioning reference signals (PRS), which may include downlink (DL) PRS, uplink (UL) PRS, sidelink (SL) PRS, or a combination thereof. The common set of PRS may be selected by the location server, e.g., based on a rough estimate of position of the UEs determined by the location server, a recommendation from the UEs, or a position report from the UEs. Once selected by the location server, an indication of the common set of PRS is sent to the UEs. The common set of PRS, alternatively, may be selected by one or more UEs, e.g., by a controlling UE or consensus, and one or more UEs provide an indication of the common set of PRS to the location server.

Abstract: Timing advance (TA) handling for sidelink (SL)-assisted positioning of a first user equipment (UE), comprises determining the first UE is configured to transmit an SL positioning reference signal (SL-PRS) to a second UE for the SL-assisted positioning. A guard period length can be determined based on a configuration of the first UE for transmitting the SL-PRS, where the guard period may comprise a period of time during which the SL-PRS is transmitted by the first UE. A message can be sent to a serving transmission reception point (TRP) of the first UE, where the message indicates the guard period and comprises a TA-related request. The TA-related request includes a request to postpone applying a TA command received by the first UE until after the guard period, or a request for the serving TRP not to send a TA command to the first UE during the guard period
