Abstract: Methods, systems, and devices for wireless communications are described. A station (STA) may receive a null data packet (NDP) on a plurality of subcarriers, and the STA may generate a channel state information (CSI) matrix for each subcarrier of the plurality of subcarriers. After generating a CSI matrix for a subcarrier, such as at least one subcarrier, the STA may scale each value in the CSI matrix using a power-of-two value to minimize complexity. Specifically, instead of scaling each value in the CSI matrix to a value between zero and one using divisions (for example, which may be computationally expensive), the STA may use shifting to scale each value in the CSI matrix. The STA may then quantize the scaled values in the CSI matrix for reporting, and the STA may transmit the quantized, scaled values in the CSI matrix in a CSI report.

Abstract: Disclosed are systems, methods, and non-transitory media for performing passive radio frequency (RF) location detection operations. In some aspects, RF data, such as RF signals including channel state information (CSI), can be received from a wireless device. The RF data can be provided to a self-supervised machine-learning architecture that is configured to perform three-dimensional (3D) object location estimation.

Abstract: Certain aspects of the present disclosure provide techniques for object positioning using mixture density networks, comprising: receiving radio frequency (RF) signal data collected in a physical space; generating a feature vector encoding the RF signal data by processing the RF signal data using a first neural network; processing the feature vector using a first mixture model to generate a first encoding tensor indicating a set of moving objects in the physical space, a first location tensor indicating a location of each of the moving objects in the physical space, and a first uncertainty tensor indicating uncertainty of the locations of each of the moving objects in the physical space; and outputting at least one location from the first location tensor.

Abstract: Techniques are provided for managing transmit and receive beams in a millimeter wave (mmW) communication system for use in bistatic radio frequency (RF) sensing. An example method of tracking targets with bistatic radio frequency sensing includes receiving one or more sensing reference signals, generating a signal report based at least in part on the one or more sensing reference signals, transmitting the signal report, receiving tracking signal configuration information, receiving one or more tracking reference signals identified in the tracking signal configuration information, and tracking one or more targets associated with the one or more tracking reference signals.

Abstract: Disclosed are techniques for environment sensing. In an aspect, a transmitter base station determines a configuration for a radio frequency (RF) sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, and transmits the RF sensing signal to at least one receiver base station based on the configuration. In an aspect, a receiver base station receives a configuration for an RF sensing signal, the configuration determined based at least in part on coordination among a plurality of base stations, receives, from at least one transmitter base station, the RF sensing signal, and detects at least one target object based, at least in part, on reception of the RF sensing signal.

Abstract: Disclosed are techniques for allocating resources for environment sensing. In an aspect, a base station transmits a first radar reference signal (RRS) on a first set of resources comprising first time resources, first frequency resources, first spatial resources, or any combination thereof, wherein the first set of resources is selected to enable a first user equipment (UE) to perform a first type of environment sensing, and transmits a second RRS on a second set of resources comprising second time resources, second frequency resources, second spatial resources, or any combination thereof, wherein the second set of resources is selected to enable a second UE to perform a second type of environment sensing, wherein the second set of resources is different from the first set of resources, and wherein the second type of environment sensing is different from the first type of environment sensing.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus obtain a signal from a remote wireless node. The apparatus may switch between a first mode and a second mode in response to the signal. The apparatus may sense the shared transmission medium and sense if an absence of traffic is detected. The apparatus may delay data transmission for a fixed time interval from detecting the absence of traffic. The apparatus may initiate the data transmission at the end of the fixed time interval if operating in the first mode or initiate the data transmission at the end of a random time interval following the fixed time interval if operation in the second mode.

Abstract: A wireless device may dynamically activate and/or inactivate wireless links for multi-link communications. A transmitting wireless device may indicate one or more wireless links to be activated by a receiving wireless device to receive subsequent multi-link transmissions. The indication may be sent over an anchor wireless link, such that the receiving wireless device may monitor the anchor wireless link, with other wireless links in an inactive or low power state, until an indication is received to activate additional wireless links. The receiving wireless device may then activate wireless links identified by the received indication, and receive data from the transmitting device via the multiple links. The activated wireless links may be inactivated upon expiration of a time duration or upon receiving a second indication to inactivate the active links. That is, indications communicated over an anchor wireless channel may identify other wireless links to be activated, inactivated, or maintained.

Abstract: Methods and systems for sounding a wireless network are disclosed. In one aspect, a method includes receiving, by an access point a message including a beamforming report from a device. The device may be a station that is outside a basic service set of the access point. The method also includes transmitting a message to the device based on the beamforming report. For example, in some aspects, the access point may utilize the beamforming report to perform a coordinated beamforming, multi-access point transmission or a multi-access point MIMO transmission. In some aspects, the access point may transmit an interference nulling signal to the device based on the beamforming report. The nulling signal compensates for another simultaneous transmission by the access point that interferes with the device's reception of a message from an access point with which the device is associated.
