    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for securing communications in a wireless communications system. A base station may determine a value that one or more user equipments (UEs) are to use for deriving a secret key for use in securing communications. A UE may use a security key generation procedure to determine the value and derive the key. According to the security key generation procedure, the UE may transmit a sounding reference signal using a first antenna of a plurality of antennas configured at the UE. The UE may then select and use the first antenna for receiving a downlink reference signal in accordance with the security key generation procedure. The UE may derive a security key using a value associated with the downlink reference signal and communicate with the base station via communications that are secured using the derived security key.

    Abstract: Methods, systems, and devices for joint sensing and data communication. A first sensing signal and a second sensing signal are transmitted in sequence, from a transmitter and using the same carrier frequency, for combined processing by a receiver. In some implementations, the sensing signals are radar signals. Data communication during an intervening time period between the first sensing signal and the second sensing signal involves the transmitter sending a data communication signal to another device or vice versa. Phase continuity between the first sensing signal and the second sensing signal can be maintained through performing radio frequency (RF) tuning on the transmitter after the transmitter transmits the data communication signal. The RF tuning may involve storing and restoring an operating state of a power amplifier in the transmitter. Alternatively, phase continuity can be maintained through preventing the transmitter from transmitting over an entirety of the intervening time period.

    Abstract: Certain aspects of the present disclosure provide techniques for securing physical (PHY) layers in wireless communication. Certain aspects are directed to a method for wireless communication by a base station (BS). In some examples, includes, by, a secured first index based at least in part on a first index and a first secret key, the first index corresponding to a first orthogonal cover code (OCC) for communication over at least a first channel between the BS and a user equipment (UE). In some examples, the method also includes transmitting, to the UE, the secured first index and the first secret key.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a network node may determine an estimated location of a user equipment (UE) that is served by a serving base station (BS). The network node may determine a dilution of precision (DOP) requirement with respect to the UE. The network node may determine at least one reconfigurable intelligent surface (RIS) that satisfies the DOP requirement with respect to the UE. The network node may send at least one configuration message to configure the at least one RIS to reflect positioning reference signals to or from the UE. In another aspect, a UE may determine a DOP requirement with respect to the UE. The UE may send at least one configuration message to select at least one RIS that satisfies the DOP requirement with respect to the UE to reflect positioning reference signals to or from the UE.

    Abstract: The present disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for channel state information (CSI) priority and multiplexing for aperiodic CSI reporting between a user equipment (UE) and a base station. The UE may receive a CSI report configuration that configures the UE to transmit a first CSI report associated with a first CSI reference signal (CSI-RS) implicitly triggered by a downlink control signal, a second CSI report associated with a second CSI-RS, or a third CSI report associated with a downlink data signal. The UE may determine that the first CSI report is scheduled to transmit on a same uplink resource as the second CSI report or the third CSI report. The UE may transmit a plurality of the first CSI report, the second CSI report or the third CSI report multiplexed on the same uplink resource based on a report prioritization.

    Abstract: Disclosed are techniques for positioning. In an aspect, a positioning entity receives a report indicating an operation mode of a reconfigurable intelligent surface (RIS) associated with at least one base station, receives a transmission-to-reception (Tx-Rx) time difference measurement for a network node involved in a round-trip-time (RTT) positioning session with a user equipment (UE), determines a reception-to-transmission (Rx-Tx) time difference measurement for the UE, the Rx-Tx time difference measurement representing a difference between a reception time at the UE of a downlink positioning reference signal from the RIS and a transmission time from the UE of an uplink positioning reference signal towards the RIS, and calculates a distance between the UE and the RIS based, at least in part, on the Tx-Rx time difference measurement and the Rx-Tx time difference measurement.
