摘要： Methods, systems, and devices for wireless communications are described for security enhancement of physical layer communications through scrambling of transmissions using a hybrid seed to generate a scrambling sequence. The hybrid seed may be determined as a function of a measured channel characteristic of a channel between a user equipment (UE) and network entity, and channel reciprocity may be used to provide that measurements at the UE and the network entity produce the same or similar measured channel characteristics. A hybrid seed may be shared with multiple UEs, in some cases, using unique characteristics of a channel between each UE and the network entity.

摘要： Methods, systems, and devices for wireless communications are described. A wireless communications system may support techniques for channel state information (CSI) based artificial noise injection. In some cases, a base station may receive an indication of CSI associated with a channel for communications with the UE. The base station may apply artificial noise signals, based on the CSI, to a set of first signals associated with control channel transmissions to obtain a set of second signals. The UE may receive the set of second signals and apply pseudo-noise signals, based on the CSI, to the set of second signals to remove or reduce the artificial noise. The UE may combine the set of second signals adjusted by applying the pseudo-noise signals to obtain a combined signal. The UE may decode the combined signal to obtain control information.

摘要： Methods, systems, and devices for wireless communications are described. Techniques described herein provide for a network entity to determine a beam focusing distance for a reconfigurable intelligent surface (RIS) for a user equipment (UE) located in the near field region of the RIS. The beam focusing distance may be determined using reference signals for different test beam focusing distances within the near field region of the RIS. The test beams may have a same angular direction from the RIS to the UE. The test beams may have a beam focusing distance selected from a set of beam focusing distances within the near field region of the RIS.

摘要： Methods, systems, and devices for wireless communications are described. For instance, first one or more wireless devices may receive or obtain a set of reference signals from second one or more wireless devices. The first one or more wireless devices may estimate a set of channel state information parameters, where each channel state parameter is based on a respective reference signal of the set of reference signals. The first one or more wireless devices may output or transmit a set of transmissions, where each transmission of the set of transmissions is based on a different gain parameter of the set of gain parameters, where each gain parameter of the set of gain parameters is based on a different channel state information parameter, and where each gain parameter of the set of gain parameters is less than a first threshold and greater than a second threshold.

摘要： 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.

摘要： Methods, systems, and devices for wireless communications are described. A network entity may apply pseudo-noise signals to repetitions of a first signal to obtain a set of second signals and transmit each of the set of second signals to a user equipment (UE) during a respective set of different time intervals. Each of the pseudo-noise signals may be associated with a gain and phase parameter, and may be based on a channel state information (CSI) associated with a channel for communications with the UE over the respective time interval. Each gain parameter may cause a power level of the pseudo-noise signal to be within a defined range, and a gain and phase parameter associated with a pseudo-noise signal applied to a subsequent repetition of the first signal may be based on another gain and phase parameter associated with another phase-noise signal applied to a previous repetition of the first signal.

摘要： Methods, systems, and devices for wireless communication are described. In some systems, a second network entity (e.g., a transmitting device) may transmit first signaling to a second network entity (e.g., a receiving device) to indicate one or more frequency domain residual sideband (FDRSB) parameters associated with the second network entity. The FDRSB parameters may be associated with an imbalance between an in-phase component and a quadrature phase component of the first signaling. The second network entity may generate and transmit second signaling that is configured to have the one or more FDRSB characteristics. The first network entity may determine whether the second network entity is a source of the second signaling based on the one or more FDRSB characteristics of the second signaling and the one or more FDRSB parameters indicated by the first signaling.

摘要： Methods, systems, and devices for wireless communications are described for physical layer signature feedback to enhance security in wireless communications. A user equipment (UE) and a network entity may apply a physical layer signature, such as an artificial physical layer impairment, to one or more physical layer signals that may be measured to identify a physical layer signature of the associated physical layer signal. The UE, upon receipt of a physical layer signal, may check if the identified signal includes a physical layer signature of a set of valid physical layer signatures. If the received physical layer signature matches a valid physical layer signature, the UE may operate in accordance with procedures associated with the signal. If the received physical layer signature does not match a valid physical layer signature, the UE may transmit a message to the network entity that indicates an unmatched physical layer signature.
