Abstract: Methods, systems, and devices for wireless communications are described, including detection of whether a first wireless device is location within a near-field distance of a second wireless device. The first wireless device measures phases of reference signals received at first antenna array of the first antenna array from a second antenna array of the second wireless device. The first wireless device determines, based on the phases, the values of quadratic terms associated with an equation for calculating the distance between a first antenna of the first antenna array and the center of the first antenna array or for calculating the distance between a second antenna of the second antenna array and the center of the second antenna array. The first wireless device determines, based on the quadratic terms, whether the first wireless device is within the near-field distance of the second wireless device.

Abstract: Certain aspects of the present disclosure provide techniques for coordinating waveform parameters and frame delays for multi-radar coexistence. An example method performed by an apparatus comprising a radar device includes transmitting, based on a transmission configuration, one or more first signals of a plurality of signals in an environment via the radar device in a first frame of a plurality of frames according to a first delay value occurring after a frame prior to the first frame and transmitting one or more second signals via the radar device in at least a second frame of the plurality of frames according to a second delay value occurring after the first frame based on the transmission configuration. In some cases, the transmission configuration comprises a common transmission configuration for use in the environment. Additionally, in some cases, the second delay value is different from the first delay value.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for mobility of a user equipment (UE) between a set of cells. A method that may be performed by a UE includes receiving signaling configuring the UE with a set of cells that support physical (PHY) layer or medium access control (MAC) layer mobility signaling and with a measurement configuration for the set of cells, reporting, to a network entity, measurements for at least some of the set of cells in accordance with the measurement configuration, and receiving, from the network entity, PHY layer or MAC layer mobility signaling to move the UE to one of the cells in the set, wherein the mobility signaling is based, at least in part, on the reported measurements.

Abstract: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Abstract: In various embodiments supporting directional security, a user equipment (UE) may receive from a network device a noise resource allocation including an indication of a noise direction and a noise parameter, generate a noise signal based at least in part on the noise parameter, and transmit the noise signal in the noise direction while transmitting a communication transmission signal in a different direction from the noise direction. In various embodiments, a network device may determine a geographic zone of interest, select one or more reconfigurable intelligent surfaces (RISs) associated with the geographic zone of interest, selecting one or more noise transmitting UEs, control the one or more noise transmitting UEs to transmit at least one noise signal, and control the one or more RISs to steer the at least one noise signal into the geographic zone of interest.

Abstract: A method of wireless communication, by a user equipment (UE), includes selecting a resource from a dedicated physical sidelink control channel (PSCCH) resource pool that has multiple potential PSCCH time domain resources with a mini-slot structure. The method also includes transmitting a mini-slot first stage sidelink control information (SCI-1) message on the selected resource. The mini-slot SCI-1 message is decoupled from a physical sidelink shared channel (PSSCH) associated with a data resource pool.

Abstract: Aspects of the disclosure are directed to a user equipment (UE) configured for detecting phase coherence failure in coherent joint transmissions (CJTs) from multiple wireless nodes (e.g., transmission/reception points (TRPs) and/or base stations). In some examples, the UE is configured to obtain signaling from a plurality of wireless nodes, the signaling including a first signal from a first wireless node of the plurality of wireless nodes and a second signal from a second wireless node of the plurality of wireless nodes. The UE is also configured to estimate a phase difference between the first signal and the second signal. In some examples, the UE is configured to output, for transmission to at least one of the first wireless node or the second wireless node, an indication of the estimated phase difference.
