Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station performs one or more angle-based measurements in a first coordinate system, determines whether to report, to a positioning entity, the one or more angle-based measurements in a local coordinate system (LCS) or a global coordinate system (GCS), and reports the one or more angle-based measurements to the positioning entity in the LCS or the GCS based on the determination. In an aspect, a positioning entity receives, from a base station, one or more angle-based measurements in an LCS of the base station or a GCS, determines whether the one or more angle-based measurements are in the LCS or the GCS, and processes the one or more angle-based measurements based on the determination.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communication systems, for example those supporting accumulated feedback, a user equipment (UE) may receive an indication of a plurality of accumulated feedback events that are each representative of different feedback combinations for reporting accumulated feedback for a set of scheduled downlink occasions and may determining the accumulated feedback for the set of scheduled downlink occasions. The UE may select, from the plurality of accumulated feedback events, a representative event based on the accumulated feedback and may transmit an uplink control message indicative of the representative event. In some examples, transmitting the uplink control message may include identifying a Huffman code for the representative event and transmitting the Huffman code via one or more stages of the uplink control message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request for an on-demand secret key to a network entity, such as if a secret key for a sidelink channel has expired before a refresh timer of the secret key expires. The UE may transmit a request for an update to a secret key associated with a first physical layer channel secured for sidelink communications based on the secret key being expired. The request may include an identifier of the first physical layer channel associated with the secret key. The UE may receive the update to the secret key based transmitting the request. In some cases, the UE may transmit an indication of the update to the secret key to a second UE.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting and processing channel state information (CSI) reference signals (CSI-RS). An exemplary method includes determining a configuration of channel state information reference signals (CSI-RSs), wherein the configuration indicates a set of resource elements (REs) to be used for CSI-RSs and a first mapping of CSI-RS ports to the set of REs; sending an indication of the configuration of the CSI-RSs; and transmitting the CSI-RSs according to the determined configuration.

Abstract: Aspects described herein relate to cross-link interference (CLI) measurement based on enhanced sounding reference signal (SRS) in fifth generation new radio (5G NR). In an example, the aspects may include receiving, by a first user equipment (UE) from a network entity, a SRS configuration; measuring, by the first UE, CLI between the first UE and a second UE based on the SRS configuration; and transmitting, by the first UE to the network entity, a measurement report of the CLI measurement to trigger CLI management between the first UE and the second UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a particular control resource set (CORESET), downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH). The UE may be configured with multi-DCI based multi-transmission/reception point (TRP) operation. The UE may determine, based at least in part on the UE being configured with multi-DCI based multi-TRP operation, a fixed higher layer index that identifies a CORESET group with which the particular CORESET is associated. The UE may perform an operation, associated with receiving the PDSCH or transmitting the PUSCH, based at least in part on the fixed higher layer index identifying the CORESET group with which the particular CORESET is associated. Numerous other aspects are provided.

Abstract: Disclosed are techniques for using sounding reference signal (SRS) for positioning. In an aspect, a UE receives an SRS configuration, the SRS configuration defining one or more SRS resource sets, each SRS resource set comprising one or more SRS resources, and each SRS resource comprising one or more SRS ports, wherein at least one SRS port of at least one SRS resource of at least one SRS resource set defined in the SRS configuration is usable by the UE at least for positioning. The UE transmits a positioning SRS utilizing one or more positioning SRS ports, wherein the positioning SRS is transmitted in a positioning SRS pattern such that across N consecutive symbols, where N is greater than or equal to two, SRS resource elements (REs) to which the one or more positioning SRS ports are mapped are staggered in frequency and use each of the N consecutive symbols.

Abstract: Methods, systems, and devices for preconfigured reference signal resources for secret key extraction are described. In some examples, a user equipment (UE) may identify a set of resources reserved for a secret key derivation process including an exchange of reference signals between the UE and a first wireless device using the set of resources. As such, the UE may transmit a first reference signal to the first wireless device using the set of resources and may receive a second reference signal from the first wireless device in accordance with the secret key derivation process. The UE may estimate a communications channel between the UE and the first wireless device and may determine the secret key based on the communications channel in accordance with the secret key derivation process. Accordingly, the UE may communicate with a selected wireless device over the communications channel using wireless communications secured using the secret key.

Abstract: During positioning of a user equipment (UE), downlink (DL) positioning reference signals (PRS) transmitted by one or more transmission reception point (TRP) in a wireless communication system may be preempted or punctured by higher priority transmissions, such as ultra-reliable low-latency traffic (URLLC). A PRS preemption indication (PI) may be provided to a UE by a serving TRP identifying one or more TRPs affected by preemption. The PRS PI may further identify the time domain and frequency domain of the preempted DL PRS transmissions. The PRS PI may identify the time domain, e.g., based on a number of PRS symbols between two monitoring occasions, wherein only PRS symbols that contain downlink positioning reference signals associated with the group of TRPs are counted. The PRS PI may identify the frequency domain by identifying at least one of four or more frequency sub-bands of the preempted DL PRS transmissions.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a reduced-capability user equipment (UE) receives, from each of one or more premium UEs, one or more parameters indicating a quality of a location estimate of the premium UE, selects at least one premium UE based on the quality of the location estimate of the at least one premium UE, and derives a location estimate of the reduced-capability UE based on the location estimate of the at least one premium UE. In another aspect, a reduced-capability UE transmits, to at least one premium UE, a request to perform one or more positioning measurements of one or more downlink reference signals, receives, from the at least one premium UE, a measurement report comprising the one or more positioning measurements, and determines a location estimate of the reduced-capability UE based on the one or more positioning measurements in the measurement report.
