Abstract: 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.

Abstract: In an aspect, a first network node may receive, from a second network node, one or more reference signals transmitted using one or more first polarizations known to the first network node, wherein the one or more reference signals are received having one or more second polarizations. The first network node may determine whether the one or more reference signals followed a line-of-sight (LOS) path between the first network node and the second network node based on a comparison of signal characteristics related to the one or more first polarizations and signal characteristics related to the one or more second polarizations.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving a reference signal (RS) configuration from a first base station. The RS configuration indicates an RS identifier (ID) of an RS associated with a second base station. The method also includes receiving the RS from the second base station based on receiving the RS configuration. The method further includes transmitting, to the first base station, an interference measurement report associated with receiving the RS from the second base station. The interference measurement report indicates the RS ID associated with the RS from the second base station.

Abstract: Aspects described herein relate to identifying an aggressor node that transmits interfering signals that cause interference to signals received at the node, communicating a configuration for applying a phase shift to the interfering signals for forwarding to the node from a reflecting node with the phase shift applied, and communicating, from the reflecting node, the interfering signals with the phase shift applied to at least partially cancel the interference to the signals received at the node.

Abstract: In some aspects, a radar device may receive a received signal comprising a reflected frequency modulated continuous wave (FMCW) radar signal and interference. The radar device may identify the reflected FMCW radar signal based at least in part on performing a phase based search procedure to facilitate removing the interference from the received signal. The radar device may perform an action based at least in part on a characteristic of the identified reflected FMCW radar signal. Numerous other aspects are described.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for techniques for wireless communications based on orbital angular momentum (OAM) modes. One aspect provides a method for wireless communications by a first wireless node. The method generally includes transmitting traffic to a user equipment (UE) on an access link, using a first portion of a uniform circular array (UCA) antenna panel and transmitting traffic to a second wireless node on a backhaul link, using a second portion of the UCA antenna panel.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may enable transmitting and receiving devices to increase an effective aperture size of transmitting and receiving antenna arrays, which may increase an achievable rank of spatially multiplexed communications. For example, one or both of the transmitting device and the receiving device may use a reflective component to reflect signals transmitted between the devices, which may allow for larger effective aperture sizes without increasing a physical distance between antenna elements. In some examples, the reflective component may be a static concave mirror associated with a predetermined weight vector and focal point. In some examples, the concave mirror may be a reflective intelligent surface (RIS) of reflective elements with reflective properties which may be dynamically adjusted to various weight vectors. An orientation of the RIS may be adjusted to steer a beam in various directions in space.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a first device may include a first circular antenna array including a first quantity of antenna subarrays. A second device may include a second circular antenna array including a second quantity of antenna arrays. Each antenna subarray may include one or more antenna elements. The first device may transmit one or more reference signals to the second device. The second device may transmit a feedback message to the first device based on the reference signals. The feedback message may include an indication of sets of beamforming weights or information for determining the sets of beamforming weights based on the second quantity of antenna subarrays being different than the first quantity of antenna subarrays. The first device may transmit one or more signals concurrently to the second device based on the sets of beamforming weights.
