Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support orbital angular momentum (OAM) communications between a transmitting device and a receiving device. The transmitting device may generate signals for transmission to the receiving device via a transmitter circle that includes a first quantity of antenna arrays. The transmitting device may transmit the signals using the transmitter circle based on multiple sets of OAM weights, where each signal may be associated with a respective set of OAM weights. The receiving device may receive the signals using a receiver circle that includes a second quantity of antenna arrays that is different than the first quantity. The receiving device may decode the signals based on multiple sets of OAM weights. The sets of OAM weights at the transmitting device and the receiving device may be based on the first quantity being different than the second quantity.

Abstract: Different antenna components of a device cause different biases in calculating a location of a user equipment (UE) based on reference signals from another device (which may be sounding reference signals from the UE or positioning reference signals from a base station). A device is configured to use different subsets of antenna components to calculate a positioning measurement. With each of the antenna components associated with a bias in calculating the positioning measurement, each subset of antenna components is associated with a bias in calculating the positioning measurement. The device is configured to generate and report an angle error group (AEG) report that is associated with the positioning measurements calculated (such as an AEG report including positioning measurements and identifiers indicating the antenna components used). The AEG report is used by a location server to identify the antenna components to be used for UE positioning operations.

Abstract: Various aspects of the present disclosure generally relate to orbital angular momentum (OAM) multiplexing based communication. In some aspects, a transmitter of OAM multiplexing based communication may determine an azimuth mode configuration for transmitting a data stream, wherein the azimuth mode configuration indicates one or more azimuth modes. The transmitter may transmit, to a receiver of the OAM multiplexing based communication, the data stream based at least in part on the azimuth mode configuration. Numerous other aspects are described.

Abstract: Aspects presented herein may enable a positioning entity (e.g., a UE, a base station, a TRP, or an LMF, etc.) to take changes in propagation delay into consideration when calculating RTT or measuring Rx-Tx timing difference for signals transmitted between a UE and a non-terrestrial device. In one aspect, a UE measures a plurality of PRSs transmitted from a non-terrestrial device. The UE calculates a propagation delay change between the UE and the non-terrestrial device based on a TDOA of the plurality of PRSs. The UE transmits, to an LMF or a location server, a UE Rx-Tx time difference associated with a UE positioning session and the propagation delay change.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for techniques for signaling control information in wireless communication systems based on orbital angular momentum (OAM) modes. One aspect provides a method for wireless communication by a transmitter. The method generally includes transmitting to a receiver, with a first orbital angular momentum (OAM) mode, a first control channel on a first time-frequency resource and transmitting to the receiver, with a second OAM mode, at least one of a data channel or a second control channel on a second time-frequency resource that at least partially overlap with the first time-frequency resource in at least one of time or frequency.

Abstract: System and techniques are described herein for providing variable rate touch sampling for touch sensors. In one illustrative example, a method of monitoring activity of a person includes obtaining one or more images of a user performing a first movement during a usage instance of an extended reality (XR) device; obtaining first biometric information of the user from at least one first biometric sensor of the XR device while the user performs the first movement; determining fatigue information of the user at least in part based on the one or more images and the first biometric information of the user; and determining an action based on the fatigue information.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communication device detects a trigger to transmit a message via satellite connectivity, determines one or more alignment opportunities associated with one or more satellites, wherein each alignment opportunity of the one or more alignment opportunities is a time period during which a main lobe of an antenna of the wireless communication device is predicted to be aligned with a line-of-sight (LOS) direction to at least one satellite of the one or more satellites, transitions to a sleep state until at least one alignment opportunity of the one or more alignment opportunities, and transmits the message to the at least one satellite of the one or more satellites during the at least one alignment opportunity of the one or more alignment opportunities.

Abstract: Aspects presented herein may enable a UE to verify the integrity of map data, thereby improving the accuracy and safety of map-aiding positioning and/or map-based positioning. In one aspect, a UE performs a map-aiding positioning based on a first set of map data. The UE verifies whether an integrity of the first set of map data meets an accuracy threshold. The UE discards the first set of map data if the verification of the integrity of the first set of map data does not meet the accuracy threshold. For example, the UE may compare the first set of map data with a second set of map data from a different source, and identify the integrity of the first set of map data does not meet the accuracy threshold if the comparison shows an indication of inconsistency above a consistency threshold.
