Abstract: A network entity (e.g., a base station) may transmit, for a network node (e.g., a RIS), a RIS pattern configuration. The network entity may transmit, for the network node, a diode bias voltage configuration for a plurality of diodes or a plurality of RIS elements of the network node. The diode bias voltage configuration may be associated with the RIS pattern configuration. The network node may forward at least one transmission from a first device to a second device via the network node in one of an uplink, a downlink, or a sidelink based on the RIS pattern configuration and the diode bias voltage configuration.

Abstract: Aspects of an apparatus for wireless communication are disclosed for collaboratively assisting a network entity to manage security at the physical (PHY) layer. A user equipment (UE) may transmit a report indicating an unauthorized network node and associated information. In response, the UE may receive from the network entity a message indicating a security measure to be applied for communications between the UE and authorized network nodes. The message may be also received in response to another report from an authorized node that includes further information about the unauthorized node. In other aspects, the network entity may receive the report from the UE and transmit the message indicating the security measure.

Abstract: A first wireless device transmits one or more transmissions for a second wireless device to a repeater for repetition to the second wireless device; adjusts a repeater operation based on a phase noise in transmission between the first wireless device and the repeater; and communicates with at least one of the repeater or the second wireless device based on the adjusted repeater operation. A repeater receives from a first wireless device, a request for the repeater to report a phase noise in transmissions between the first wireless device and the repeater for repetition with a second wireless device; and transmits a report of the phase noise to the first wireless device based on the request. A repeater receives, from a first wireless device, a transmission for repetition with a second wireless device; and transmits the repetition of the transmission to the second wireless device with a phase noise compensation.

Abstract: A network node may select a reference AM/PM impairment signature. The network node may transmit, to a UE, a first indication of the reference AM/PM impairment signature via a security signal. The network node may transmit, to the UE, at least one reference signal via a downlink channel. The at least one reference signal may include added AM/PM impairment based on the reference AM/PM impairment signature. The UE may receive, from a transmitter, at least one reference signal via a downlink channel. The UE may estimate an AM/PM impairment signature in the at least one reference signal. The UE may identify whether the estimated AM/PM impairment signature matches a reference AM/PM impairment signature. Further, the UE may maintain or discard at least one slot associated with the downlink channel based on whether the estimated AM/PM impairment signature matches the reference AM/PM impairment signature.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the techniques described herein may enable information transfer via channel-adaptive space time block codes (STBCs) over reconfigurable intelligent surfaces (RISs). For example, a network entity may transmit a control message indicating a set of parameters associated with an STBC of multiple STBCs associated with a RIS, where the set of parameters includes a size of the STBC. The network entity may transmit, to the RIS, a downlink message and the RIS may encode one or more information bits on the downlink message according to the parameters associated with the STBC. Additionally, the RIS may reflect the downlink message to a UE based on the set of parameters, where the reflected message includes the one or more information bits, and the UE may identify the one or more information bits based on a detection procedure associated with the set of parameters.

Abstract: A network node may identify at least one adversarial device. The network node may transmit a fake configuration to the at least one adversarial device. The fake configuration may be associated with a PHY technique. The fake configuration may be transmitted to the at least one adversarial device based on a location of the at least one adversarial device. The at least one adversarial device may be identified based on non-possession by the at least one adversarial device of any valid credential. The network node may transmit a correct configuration to a genuine receiving device. The network node may transmit the fake configuration and the correct configuration in parallel or based on time division multiplexing. Accordingly, security of the overall system may be improved as the adversarial device may waste time and power performing algorithmic operations based on the fake configuration.

Abstract: A first network node may transmit an authentication proof to a second network node. The authentication proof may be based on a first credential associated with the first network node. The first network node may be authenticable based on the authentication proof. The second network node may identify whether the first network node is authentic based on the authentication proof. The second network node may transmit a configuration request to the first network node. The configuration request may include a phase-modulated indication of a second credential associated with the second network node. The configuration request may be based on a random phase. The second network node may be authenticable based on the configuration request. The first network node may transmit a configuration response to the second network node. The configuration response may include a phase-modulated confidential parameter. The configuration response may be based on the configuration request.

Abstract: Method and apparatus for dynamic control of power amplifier back off for repeaters. The apparatus uses a channel model to model a first signal at a channel output. The channel model models a channel between a receiver and a transmitter. The apparatus performs a PAPR reduction on the first signal at the receiver to generate a second signal having a reduced PAPR. The apparatus inputs the second signal through an inverse channel model to generate an output signal. The apparatus outputs the output signal to the receiver, such that the PAPR of the output signal is reduced at an input of the receiver.
