Abstract: A method of measurement gap (MG) configuration of a first user equipment (UE) for sidelink positioning reference signal (SL-PRS) measurements comprises determining, at a network node, information regarding a first positioning reference signal (PRS) measurement to be made by the first UE. The first PRS measurement may comprise an SL-PRS measurement. The method also comprises determining, at the network node, information regarding a second PRS measurement. The method also comprises determining an MG configuration, where the MG configuration schedules at least one MG for at least one period of time during which during which the first UE is to make the first PRS measurement, and the MG configuration is based at least in part on the information regarding the first PRS measurement and the information regarding the second PRS measurement. The method also comprises sending the MG configuration to the first UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) performs one or more time-based measurements of one or more first positioning reference signal (PRS) occasions transmitted by a first transmission-reception point (TRP), the one or more first PRS occasions having a first bandwidth, receives an indication to switch from measuring PRS occasions from the first TRP in the first bandwidth to measuring PRS occasions from the first TRP in a second bandwidth, and performs one or more angle-only measurements of one or more second PRS occasions transmitted by the first TRP, the one or more second PRS occasions having the second bandwidth.

Abstract: In an aspect, a communications device (e.g., UE, BS, LMF component, etc.) determines information related to a first positioning reference signal (PRS) configuration (e.g., UL-PRS configuration such as SRS-P, or DL-PRS configuration) associated with a user equipment (UE), determines information related to a first discontinuous reception (DRX) configuration associated with the UE, determines that a first PRS operation requirement of the first PRS configuration is not satisfied by the first DRX configuration due to a DRX limitation condition, and perform an action in response to the determination that the first PRS operation requirement of the first PRS configuration is not satisfied by the first DRX configuration due to the DRX limitation condition.

Abstract: A method of performing positioning operations at a user equipment includes: operating the user equipment in a discontinuous reception mode including time interleaved ON times of the discontinuous reception mode and OFF times of the discontinuous reception mode; and determining, at the user equipment, whether to measure a portion of a positioning signal based on timing of the portion of the positioning signal relative to at least one of a first one of the ON times of the discontinuous reception mode or a first one of the OFF times of the discontinuous reception mode.

Abstract: A method comprises: selecting, from a first number of first receive (RX) beams having a first beam width, a first RX beam to form a first beam-pair with a first transmit (TX) beam from one or more base stations, the selection being based on a first measurement of a first reference signal received by the UE using the first beam-pair; selecting, from a second number of second RX beams having a second beam width, a second RX beam to form a second beam-pair with the first TX beam, the selection being based on a second measurement of a second reference signal received by the UE using the second beam-pair, the second number of second RX beams being smaller than the first number of first RX beams, the second beam width being narrower than the first beam width; and performing a location estimate operation using either the second beam-pair, or a third beam-pair derived from the second beam-pair.

Abstract: Various aspects relate generally to the beam management procedures in wireless communications systems. Some aspects more specifically relate to the selection of beams for communications to and from a UE and a network entity based on quantized orientation information for a user equipment (UE). In some implementations, a network entity can use the quantized orientation information and a machine learning model to predict a set of beams that may be suitable for communications to and from the UE and the network entity, which may be a subset of the beams that the network entity can generally use for communications to and from the UE and the network entity.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a serving cell, an uplink positioning reference signal (UL-PRS) resource configuration, the UL-PRS resource configuration comprising a plurality of N resource elements (REs) staggered in frequency across a plurality of M consecutive symbols of a resource block (RB) such that the plurality of N REs spans a plurality of N consecutive subcarriers of the RB, receives, from the serving cell, an indication of a PRS symbol cancelation group to be used for uplink cancelation, the PRS symbol cancelation group identifying a set of the plurality of M consecutive symbols that is expected to be canceled for uplink transmission, and cancels transmission of UL-PRS on one or more of the set of L symbols identified by the PRS symbol cancelation group.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines determining whether to perform a power headroom report (PHR) function for a pathloss reference signal (PL-RS). Based on the determination, the UE performs a PHR function or one or more pathloss measurements for the PL-RS based on the determination. In some aspects, the determination is based on a PL-RS type or cell type associated with the PL-RS. In other aspects, the determination is based on an indication (e.g., explicit or implicit indication) associated with the PL-RS that is received from a serving cell of the UE; and

Abstract: Certain aspects of the present disclosure provide techniques for measurements on a first frequency band applicable to procedures on a second frequency band. A technique that may be performed by a user equipment (UE) may include sending a base station (BS) an indication of the first frequency band, which may be a preferred measurement frequency band. The UE may then measure one or more reference signals (RSs) on the preferred measurement frequency band. The UE may then apply the measurements of the one or more RSs on the preferred measurement frequency band for one or more procedures on the second frequency band.
