Abstract: Techniques and systems are provided for attention evaluation by an extended reality system. In some examples, the system determines one or more regions of interest (ROI) for an image displayed to a user. The system may also receive eye tracking information indicating an area of the image that the user is looking at. The system may further generate focus statistics based on the area of the image at which the user is looking at and the one or more ROI; and output the generated focus statistics.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may determine a reference location associated with a virtual image corresponding to a target area. The network node may transmit a radio frequency signal, wherein the radio frequency signal is beamformed based at least in part on the reference location to direct the radio frequency signal to the target area. Numerous other aspects are described.

Abstract: Certain aspects relate to techniques for estimating and compensating for antenna array rotation of a wireless node. For example, the antenna array of the wireless node may rotate about one or more of an x-axis, a y-axis, and a z-axis, which may misalign the antenna array relative to another antenna array of another wireless node, causing degradation of communications between the two nodes. In some examples, the wireless node may obtain, from a first antenna array of the other wireless node via a second antenna array of the first wireless node, a first pilot signal and a second pilot signal via a first beam. In some examples, the first wireless node may perform a first alignment compensation based on a phase difference between the first pilot signal and the second pilot signal.

Abstract: Apparatus, methods, and computer-readable media are disclosed herein for orbital angular moment capability in millimeter wave and higher frequency bands. An example method for wireless communication at a first communication device includes transmitting, to a second communication device, OAM capability information indicating a capability to receive an OAM waveform. Additionally, the example method includes receiving one or more OAM transmissions from the second communication device, the one or more OAM transmissions based on the OAM capability information.

Abstract: Aspects of the disclosure relate to reporting and correcting a spatial misalignment of an orbital angular momentum (OAM) waveform communicated from a second device to a first device. In an aspect, the first device receives from the second device, the OAM waveform having a spatial misalignment with respect to the second device. The first device determines the spatial misalignment and further determines spatial coordinates for correcting the spatial misalignment and/or one or more channel measurements of the OAM waveform. Thereafter, the first device sends a report based on the spatial misalignment to the second device, the report including the spatial coordinates for correcting the spatial misalignment and/or the one or more channel measurements. The first device then receives an adjusted OAM waveform from the second device, wherein the adjusted OAM waveform is received having a corrected spatial alignment with respect to the second device based on the report.

Abstract: The present disclosure relates to methods and devices for wireless communication of an apparatus, e.g., a UE and/or a base station. The apparatus may perform a ML procedure based on at least one initial ML capability of the UE. The apparatus may also determine at least one updated ML capability for the ML procedure corresponding to an update to the at least one initial ML capability. Further, the apparatus may transmit, to a base station, an indication of the at least one updated ML capability for the ML procedure. The apparatus may also perform the ML procedure based on the at least one updated ML capability or based on the at least one initial ML capability.
