Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may obtain an estimate of a transmission channel. The transmitter device may transmit, via the transmission channel, a communication having tone reservation applied to tone reservation (TR) subcarriers based at least in part on parameters of the transmission channel. Numerous other aspects are described.

Channel aware tone reservation

Methods, systems, and devices for wireless communications are described. A device may be configured to include an array of lenses along with multiple antenna arrays that each include a set of antenna elements. The antenna arrays may each support multiple beam directions, such as a respective beam direction for each lens of the array of lenses. If beams for multiple antenna arrays concurrently pass through the same lens, the lens may contribute to maintaining separation between the beams. Lenses may also contribute to the shaping of beams, and the use of multiple lenses may enhance a coverage area for beams transmitted or received by the antenna arrays.

Wireless communications using multiple antenna arrays and a lens array

Systems and techniques are described herein for wireless communication. For example, a computing device (e.g., a user equipment or component thereof) can obtain channel estimation of at least one channel for communication with a network device. The computing device can obtain a location parameter associated with the computing device. The computing device can determine, based at least on the channel estimation, one or more large scale parameters (LSPs). The computing device can further generate an LSP vector associated with the one or more LSPs. The computing device can transmit, to the network device, the LSP vector and the location parameter of the computing device.

Generation of complete large scale parameter maps

Methods, systems, and devices for wireless communications are described. A wireless device (e.g., a base station) may transmit, to a user equipment (UE), an indication of a field type of a field between the UE and the wireless device. The indication of the field type may include one or more bits indicating the field type, a measure indicating a likelihood that the field type includes a first field type as compared to a second field type, an indication that the first type is the same as a second field type configured at the UE, or any combination thereof. The UE may select between a first set of beam weight vectors and a second set of beam weight vectors based on the field type. The UE may communicate, with the base station, a reference signal using a beam generated using a first beam weight vector from the selected set.

Holographic-MIMO field type indication

Methods, systems, and devices for wireless communications are described. A first wireless node may transmit, to a second wireless node, an indication of an orbital angular momentum (OAM) base value that is associated with one or more OAM modes. The OAM base value may correspond to a number of antenna elements of an antenna ring at the first wireless node, and for each of the one or more OAM modes. Based on the OAM base value, the first wireless node may communicate reference signaling according to the one or more OAM modes using the number of antenna elements of the antenna ring. The second wireless node may use a same number of antenna elements based on the indicated OAM base value.

Orbital angular momentum communication with variable antenna number

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for lens design for full-duplex communication. In some aspects, a device may use a lens design that enables full-duplex operation through a lens by facilitating an avoidance or mitigation of self-interference during full-duplex operation. The lens may have a first, antenna-facing surface and a second, outward-facing surface and, to avoid or mitigate self-interference due to reflection off the lens, the first surface may have a first curvature associated with a relatively small radius. In such examples, the device may transmit wireless signaling from a transmitting element and a reflection off the lens may be dispersed or otherwise oriented away from a receiving element in accordance with a design of the first curvature. In some implementations, the lens may include an anti-reflective coating to further reduce reflection off the lens.

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may detect a material proximate to the UE and may determine one or more properties of the material which may affect beamformed communications. The UE may transmit (e.g., based on the detected material) an indication of a switch from a codebook-based hybrid beamforming procedure to an adaptive beam weight-based hybrid beamforming procedure. The UE may receive, from a network entity, one or more reference signals to use for adaptive beam weight selection in response to the indication of the switch to the adaptive beam weight-based hybrid beamforming procedure. The UE may communicate, with the network entity, in accordance with one or more beam weights selected based on the adaptive beam weight-based hybrid beamforming procedure and the one or more reference signals.

Switching to an adaptive beam weight-based hybrid beamforming procedure

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.

Fatigue detection in extended reality applications

Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support orbital angular momentum (OAM) communications. A transmitting network node may generate signals for transmission via a first circular antenna array that includes a first quantity of antenna subarrays. The transmitting network node may transmit the signals using the first circular antenna array and based on OAM vectors. The receiving network node may receive and decode the signals using a second circular antenna array that includes a second quantity of antenna subarrays and based on the OAM vectors. The OAM vectors may be based on a numerical relationship between the first quantity and the second quantity. The numerical relationship may include the first quantity being equal to a product of the second quantity and a non-integer rational number and a greatest common divisor of the first and second quantities being an integer greater than one.

Orbital angular momentum multiplexing based on a common factor between quantities of transmit and receive antenna subarrays

A first device may receive, from a second device, perception information for an environment of the first device based at least in part on a perception capability of the second device. The first device may generate a perception associated with a communication by the first device based at least in part on the perception information from the second device, where the perception indicates characteristics of the environment. The first device may adjust a parameter associated with the communication based at least in part on the perception. Numerous other aspects are described.

Perception-assisted wireless communication

A multimedia production method includes: reusing the content in the introduction before the main content or other part in the multimedia file for an outroduction after the main content and playing the audio and/or video content in the reverse direction. A producer can make the multimedia file by attaching such an outroduction. A multimedia editing program can provide a user interface with menu options for such a production technique. The media production program could be associated with the multimedia sharing and distributing network. Such a production method could be applied to multiple multimedia files in the same media sharing and distributing network by the same producer. The same content can be reused in a cluster of media files.

Audio/video outroduction by reusing content from introduction and other parts

Disclosed are techniques for wireless sensing. In an aspect, a user equipment (UE) detects an object and a direction to the object in an environment of the UE, determines whether the object is a human, identifies, based on the object being the human, a sensitive body part of the human, and performs, based on identification of the sensitive body part, a maximum power exposure (MPE) mitigation operation.

Multi-sensor assisted maximum power exposure (MPE) operations for millimeter wave (MMW) communications

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently determining a region in which a user equipment (UE) is located. The UE may perform measurements on reference signals received from a first network entity to determine the region in which the UE is located. In some cases, the UE may provide the measurements or other information to a second network entity, and the second network entity may indicate the region in which the UE is located to the UE based on the measurements or the other information. The second network entity or the UE may also indicate the region in which the UE is located to the first network entity. The UE and the first network entity may then select suitable beams for communicating based on the region in which the UE is located.

Device region estimation for near-field operation

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.
