Abstract: Implementations of a sensing headroom report (HR), generating the sensing HR, and adjusting transmit powers and other parameters are described. A device transmits a radar wireless signal at a first transmit power from one or more transmit chains. The device also senses the radar wireless signal. The device generates a sensing HR based on sensing the radar wireless signal. The sensing HR may include one or more indications of metrics associated with a received power, such as a transmit power headroom, a sensing headroom, or a combination of a self-interference power, noise, and received power. The device provides the sensing HR to another device in the wireless network (such as via a base station and/or core network to a radar server), and another device may determine a transmit power or other device parameters to be used for sensing.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may determine to change a power mode of the UE to a new power mode. The UE may change the power mode of the UE to the new power mode, wherein if the new power mode comprises a power saving mode, the UE measures positioning reference signals (PRSs) from one transmission/reception point (TRP), and wherein if the new power mode is a normal power mode, the UE measures PRSs from two or more TRPs.

Abstract: Techniques are disclosed for using reference signals that enable accurate measurements of a moving UE. To this end, techniques can include a location server obtaining an indication that the velocity of the UE exceeds a threshold and, in response, configuring the UE to measure a reference signal using a selected Tracking Reference Signal (TRS) as a Quasi-Collocation (QCL) reference. In particular, a periodic TRS (P-TRS) or an aperiodic TRS (AP-TRS) can be used as the QCL reference. A reference signal may be configured based on an existing TRS configuration, or a TRS may be configured based on a reference signal configuration. According to some embodiments, a UE may provide velocity information to the location server. Additionally or alternatively, a measurement period for the reference signal may be based on a velocity of the UE.

Abstract: Disclosed are techniques for positioning. In an aspect, a network node receives, from a network entity, one or more parameters for a neural network, performs one or more measurements of at least one reference signal from a target user equipment (UE) based on a measurement configuration for the at least one reference signal, generates one or more statistics of one or more features of the at least one reference signal based on the neural network and the one or more measurements, and reports the one or more statistics to the network entity to enable the network entity to estimate a location of the target UE based on the one or more statistics and a location of the network node.

Abstract: A method of providing positioning state information in a channel usable for conveying the positioning state information includes: obtaining a positioning state information resource allocation parameter; determining a positioning resource amount based on the positioning state information resource allocation parameter, the positioning resource amount being an amount of resources of the channel usable for conveying the positioning state information; and transmitting the positioning state information over the channel while occupying no more than the positioning resource amount of resources of the channel.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) measures one or more positioning reference signal (PRS) resources of at least one PRS instance, and processes the one or more PRS resources of the at least one PRS instance during a PRS processing gap, wherein the PRS processing gap comprises a period of time during which the UE prioritizes PRS processing over reception, processing, or both of other downlink signals and channels.

Abstract: A UE receives, from a BS, information indicating a first TEG delay at the BS for a transmission of a first PRS, a second TEG delay at the BS for a reception of an SRS from the UE, a third TEG delay at the BS for a transmission of a second PRS, a fourth TEG delay at the BS for a transmission of the first PRS and a reception of the SRS from the UE, or a fifth TEG delay at the BS for a reception of the SRS from the UE and a transmission of the second PRS, or any combination thereof. The UE determines a double RTT based on a first PRS timing associated with a reception of the first PRS, an SRS timing associated with a transmission of the SRS, a second PRS timing associated with a reception of the second PRS, and the received information.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) transmits an uplink reference signal towards a first reconfigurable intelligent surface (RIS) associated with at least one base station, receives, from the first RIS, a reflection of the uplink reference signal, wherein at least one transmission parameter of the reflection identifies the reflection as the reflection of the uplink reference signal, and enables a distance between the UE and the first RIS to be calculated based, at least in part, on a transmission-to-reception (Tx-Rx) time difference measurement for the UE, the Tx-Rx time difference measurement representing a difference between a transmission time from the UE of the uplink reference signal to the first RIS and a reception time at the UE of the reflection of the uplink reference signal from the first RIS.
