Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a network entity, a positioning reference signal (PRS) configuration indicating one or more PRS resources. The UE determines that one or more transmission properties of the one or more resources should be modified and transmits PRS modification information to the network entity based on the one or more transmission properties of one or more PRS resources to be modified. The network entity may be a location server or location management function. The PRS modification information may include a request to modify the PRS configuration and information indicating a start time, a stop time, a duration, or a combination thereof, associated with modifying the PRS configuration.

Abstract: Positioning for user equipments (UEs) in a wireless network is supported by restricting position reference signal (PRS) configuration parameters for a Transmission Reception Point (TRP) based on PRS configuration used by co-located TRPs. The PRS configuration parameters for the TRP may be restricted by restricting orthogonality of the PRS resources with respect to PRS resources from co-located TRPs to only code division multiplexing, and other types of orthogonality such as time division multiplexing and frequency divisional multiplexing are not permitted for co-located TRPs. The PRS configuration parameters for the TRP may be restricted to the same muting sequence type, e.g., inter-instance and/or intra-instance muting, as used by co-located TRPs. The PRS configuration parameters, e.g., related to orthogonality and/or muting, are not restricted with respect to non-co-located TRPs. The restrictions on the PRS configuration parameters for a TRP may be determined by a central authority, such as a location server.

Abstract: In an aspect, a UE receives first positioning assistance data (AD). The UE transmits an indication to a network component (e.g., BS, core network component, LMF, etc.) that the UE has received the first positioning AD. The network component determines second positioning AD that is based at least in part upon the first positioning AD. The network component transmits the second positioning AD to the UE.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may determine a plurality of measurement gap (MG) configurations, each MG configuration defining one or more MGs. The UE may send, to a serving base station, a request to use a first MG configuration from the plurality of MG configurations, and may receive a response to the first request. The UE then measures positioning signals using an MG configuration indicated by the response. Based on measurements of the first set of positioning signals, the UE may select a second MG configuration, send a second request to use the second MG configuration, and receive a response to the second request. The UE then measures a second set of positioning signals using an MG configuration indicated by the response to the second request.

Abstract: A method of managing positioning reference signal transmission includes: instructing a transmission point to apply a muting pattern regarding transmission of a reference signal including first and second reference signal resources, where a first instance of the first reference signal resource includes one or more first resource elements across one or more first OFDM symbols within a slot, and a second instance of the second reference signal resource includes one or more second resource elements across one or more second OFDM symbols within the slot; and instructing the transmission point to transmit, unmuted, at least one of the one or more second resource elements, of at least one of the one or more second OFDM symbols, despite the muting pattern indicating to mute transmission of the at least one of the one or more second resource elements of the at least one of the one or more second OFDM symbols.

Abstract: Examples described herein relate to managing communications on a first subscription and a second subscription of a multi-Subscriber Identity Module (SIM) wireless communication device via a Radio Frequency (RF) resource, including, but not limited to, tuning the RF resource away from the second subscription to the first subscription, detecting a network-set activation state of a secondary cell associated with the first subscription, and adjusting the activation state of the secondary cell based on the network-set activation state.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that provide managing transmissions of sidelink positioning reference signals (PRS) with a timing advance offset (TA) from a sidelink node. In aspects, a sidelink node (e.g., a target user equipment (UE) or an assisting UE) may receive transmissions from a plurality of nodes (e.g., target UEs or assisting UEs). The sidelink node obtains at least one TA to be used by a transmitting node of the plurality of nodes for transmitting a sidelink PRS to the sidelink node (e.g., to advance the sidelink PRS transmission to the sidelink node with respect to the timing of the first transmission). The TA is an offset obtained by the sidelink node based on the receiving times of the transmissions from the plurality of nodes. The sidelink node may receive PRS transmissions from the plurality of nodes in a same symbol aligned within the same CP.

Abstract: A mobile device supports positioning with positioning reference signals (PRS) on multiple beam by dividing the PRS processing into two separate modes, an acquisition mode and a tracking mode. In acquisition mode, the mobile device performs a fast scan of all of the beams from a base station transmitting PRS using less than the full set of resources for the PRS, i.e., less than the full bandwidth and/or less than the full number of repetitions of the PRS. The mobile device may select the best beams to use for positioning, e.g., based on signal strength metric. In tracking mode, the mobile device tracks the PRS from only the selected beams using the full set of resources for the PRS. The mobile device may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) determines at least one random access channel (RACH) preamble from a first set of RACH preambles, wherein the first set of RACH preambles is for positioning purposes and a second set of RACH preambles is for communication purposes, and wherein the first set of RACH preambles and the second set of RACH preambles are associated with at least one transmission-reception point (TRP), transmits, to the at least one TRP, the at least one RACH preamble to indicate that the UE is involved in a positioning session, receives, from the at least one TRP, in response to transmitting the at least one RACH preamble, an allocation of one or more resources for transmission of uplink positioning signals for the positioning session, and transmits the uplink positioning signals via the one or more resources.
