Abstract: Methods, systems, and devices for wireless communications are described. For instance, a wireless device may measure a first portion of a cyclic prefix (CP) of a wireless transmission received using a first subset of a set of analog receive elements. The wireless device may measure a second portion of the CP of the wireless transmission using a second subset of the set of analog receive elements. The wireless device may determine a beam gain for the set of analog receive elements based on measuring the first portion of the CP received using the first subset and the second portion of the CP received using the second subset. In some examples, measuring using the first subset and the second subset may be associated with improved automatic gain control performance and/or transmission power control as compared to measuring with each of a set of analog receive elements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may obtain a first channel matrix associated with communications between a transmitter device transmission antenna and a transmitter device reception antenna and a second channel matrix associated with communications between the transmitter device transmission antenna and a receiver device reception antenna associated with a receiver device. The transmitter device may generate a combined channel matrix based at least in part on the first channel matrix and the second channel matrix. The transmitter device may reduce interference between the transmitter device transmission antenna and the transmitter device reception antenna based at least in part on multiplying the combined channel matrix by a precoding matrix. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may manage a shape of a beam to selectively reduce interference at one or more wireless nodes. The base station may receive a capability message from a first wireless node indicating a capability of the first wireless node to support one or more beam tapering configurations. In some cases, the base station may receive an interference report from a second wireless node, indicating that the first wireless node caused interference at the second wireless node. The base station may transmit a beam tapering configuration of the one or more beam tapering configurations to the first wireless node, and the first wireless node may transmit a beamformed message to the base station according to the beam tapering configuration. In some cases, the beam tapering configuration may be associated with less interference when transmitting the beamformed message.

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 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a node, a list of frequency allocations that are associated with interference at the UE. The UE may communicate in accordance with the list of frequency allocations. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for applying digital pre-distortion with frequency selectivity to a transmission signal. An example technique includes determining one or more target parameters of an input signal, the one or more target parameters being based on frequency of the input signal. The technique also includes applying digital pre-distortion with frequency selectivity to the input signal according to the one or more target parameters of the input signal to generate a resulting signal. The technique further includes processing the resulting signal to generate an analog signal for transmission and transmitting the analog signal.

Abstract: In some aspects, a UE may select a first type of antenna for communication with a base station based at least in part on a beam management procedure that uses an RSRP parameter determined using a downlink reference signal associated with a single antenna port; measure a CSI-RS resource for CSF, associated with multiple antenna ports, using a second type of antenna and after selecting the first type of antenna; compare a first spectral efficiency parameter associated with communicating using the first type of antenna and a second spectral efficiency parameter determined based at least in part on measuring the CSI-RS resource for CSF using the second type of antenna; and select one of the first type of antenna or the second type of antenna for subsequent communication with the base station based at least in part on comparing the first spectral efficiency parameter and the second spectral efficiency parameter.

Abstract: Certain aspects of the present disclosure provide techniques for digital pre-distortion (DPD). An apparatus for wireless communication generally includes a power amplifier (PA); a first DPD circuit, a second DPD circuit, and a transmitter. The first DPD circuit is generally configured to: obtain an input signal; apply a first DPD to the input signal to generate a first resulting signal; and output the first resulting signal to the second DPD circuit. The second DPD circuit is generally configured to: obtain the first resulting signal from the first DPD circuit; apply a second DPD to the first resulting signal to generate a second resulting signal; and output the second resulting signal to the PA. The PA is generally configured to amplify the second resulting signal to generate an amplified second resulting signal. The transmitter is generally configured to transmit the amplified second resulting signal to a second apparatus.
