Abstract: In an aspect, a first UE transmits SL-PRS to a second UE based on a bandwidth associated with DL-PRS(s) from one or more gNBs to the second UE in association with a positioning procedure of the second UE. In other aspects, a network component (e.g., LMF UE, etc.) triggers transmission of a WLAN ranging signal from a first UE to a second UE (e.g., to supplement an NR-based positioning procedure).

Abstract: According to embodiments herein, a UE can be configured with a spatial relationship for an Uplink Position Reference Signal (UL-PRS) to transmit via the SL interface. This information can include various options related to a transparent mode in which an anchor UE connected with the UE via the SL interface generally acts like a base station. In an advanced mode, any of a variety of aspects of the SL interface used in communication between the UE and anchor UE may be used as a reference for UL-PRS.

Abstract: A positioning signal processing method at a user equipment includes: operating the user equipment in a discontinuous reception mode including time interleaved ON times of the discontinuous reception mode, during which the user equipment is in an active mode monitoring for a positioning signal measurement trigger signal, and OFF times of the discontinuous reception mode, during which the user equipment is in an inactive mode; receiving a wake-up signal at the user equipment; and determining, at the user equipment, whether to measure a positioning signal based on whether the wake-up signal indicates to implement the active mode during a scheduled discontinuous reception mode ON time or to skip the scheduled discontinuous reception mode ON time.

Abstract: Frequency-dependent changes in beam shapes of transmitted RF signals can be provided to a receiving device. Beam shape information can include, for example, gain of a beam and a plurality of azimuth and elevation directions, boresight and width of a main lobe (and optionally side lobes) of the beam, information regarding a pattern of antenna elements of an antenna panel used to transmit the beam, and/or similar information. The type of information provided can dictate the amount of overhead required, and we therefore vary depending on the means by which the information is conveyed. Additional detail is provided in the embodiments described herein.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a network node receives a reference signal comprising a plurality of time and frequency resources, the plurality of time and frequency resources spanning a plurality of disjoint bandwidth segments, the plurality of disjoint bandwidth segments being time aligned or having a known time offset with respect to each other, and determines a time of arrival (ToA) of the reference signal based on jointly processing the plurality of time and frequency resources of the reference signal across the plurality of disjoint bandwidth segments.

Abstract: Various aspects of the present disclosure relate to beam management procedures in wireless communications systems. Some implementations of the present disclosure more specifically provide techniques for reporting measurements for proposed beams (such as beams predicted to be the best beams for communications to and from a UE and a network entity) and other beams detected by the UE. The techniques may be used, for example, to identify mismatches between a proposed set of beams and actual best beams for communications to and from a UE and a network entity and allow for the retraining of machine learning models used to identify the proposed set of beams for communications to and from a UE and a network entity.

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: A method of wireless communication, executed by a user equipment (UE), receives, from a base station, a broadcast or multicast message including a known payload, as well as a configuration for the known payload. The method also trains an artificial neural network with the known payload. A method of wireless communication, executed by a base station, configures a known payload for multiple UEs and signals, to the UEs, an indication of which physical channel will include the known payload, as well as time/frequency resources of the known payload. The method also broadcasts or multicasts the known payload to facilitate neural network training at the UEs.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines old and new pathloss vectors that track old and new pathloss values on an element-specific basis. For a respective element, the UE selectively triggers a PHR based upon respective old and new pathloss values for that element. In another aspect, the UE determines whether differential pathloss value between two respective pathloss values associated with two pathloss measurement attempts for an element is unavailable or (if available) is higher than a threshold value, and the UE selectively triggers a PHR for the element based on the determination.

Abstract: A method of wireless communication by a user equipment (UE) may include receiving a message requesting estimated channel characteristics of a secondary band based on measuring characteristics of a channel in the primary band. The method also includes measuring characteristics of the channel in the primary band. The method estimates channel characteristics of the secondary band based on the primary band characteristics measurements. The estimating may occur without measuring signals in the secondary band. Further, the method may report the estimated channel characteristics of the secondary band and receive an indication of a secondary cell group, based on the estimated channel characteristics of the secondary band.
