Abstract: Methods and apparatus for performing automatic gain control (AGC) in bypass and filter modes for radio frequency (RF) front-end circuitry are described. An example method includes operating a receiver in a first mode during a first set of symbols of a first subframe. The method also includes, during a first symbol of the first subframe outside the first set of symbols, determining whether to operate the receiver in the first mode or a second mode in a second subframe, based at least in part on an output of a jamming detection circuit of the receiver in the first symbol. The method also includes controlling the receiver to operate in the first mode or the second mode in the second subframe, in accordance with the determination.

Abstract: Certain aspects of the present disclosure provide apparatus and methods for cellular vehicle-to-everything (C-V2X) stationary object detection. One example radio frequency (RF) front-end circuit generally includes a directional coupler having a first port for coupling to an antenna and having a second port; and a delta switch having a first port coupled to the second port of the directional coupler, having a second port, and having a third port for coupling to a receive path for detection of a stationary object. The RF front-end circuit and methods for C-V2X stationary object detection may allow for concurrent (i) stationary object detection and (ii) C-V2X signal reception or transmission.

Abstract: In certain aspects, a system includes a first filter, a second filter, a dummy load, and a switching circuit coupled to the first filter, the second filter, and the dummy load, and coupled to a first antenna and a second antenna. In a first mode, the switching circuit couples the first filter and the second filter to the first antenna, and, in a second mode, the switching circuit couples the first filter and the third filter to the first antenna and couples the second filter to the second antenna. In certain aspects, the dummy load includes a third filter.

Abstract: Certain aspects of the present disclosure introduce transmit chain asymmetry to meet tighter specifications of a band on one side of a spectrum while sacrificing emissions margin of a band on the opposite side of the spectrum. One example apparatus generally includes a distortion module configured to generate an input signal, and an amplifier coupled to the distortion module and configured to generate an amplified signal based on the input signal. In certain aspects, the input signal is generated such that a power of the amplified signal at a first bandwidth is skewed relative to a power of the amplified signal at a second bandwidth, the first and second bandwidths being adjacent to a main channel bandwidth of the amplified signal.

Abstract: A user equipment may be configured to limiting transmit power for frequency domain division for high power user equipment. In some aspects, the user equipment may determine a UE context is interference limited or noise limited based on comparing a measurement value to a threshold value, set a maximum transmit power based on the UE context, and transmit, during a time period associated with a downlink (DL) grant, an uplink (UL) transmission at the maximum transmit power.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive a configuration indicating a parameter of a signal to be optimized for a portion of a frequency range. The wireless node may transform a feedback signal and a reference signal into a frequency domain. The wireless node may generate an error signal based at least in part on transforming the feedback signal and the reference signal. The wireless node may assign weights to the error signal to generate a weighted error signal. The weights may be assigned to the error signal in the portion of the frequency range and a remaining portion of the frequency range according to the configuration. The wireless node may transmit the signal based at least in part on utilizing the weighted error signal to apply digital pre-distortion to the signal. Numerous other aspects are described.

Abstract: Methods and apparatuses are described that facilitate data communication across a serial bus. In one configuration, a transmitter configures a plurality of devices by assigning one or more trigger registers to each device of the plurality of devices and sends to each device a trigger register assignment command indicating a trigger register assigned to a device and identifying a trigger corresponding to the device. The transmitter then addresses a packet to an assigned trigger register and generates a bit-index field in the packet. Bits in the bit-index field respectively represent triggers corresponding to devices associated with the assigned trigger register, wherein each bit indicates whether one or more corresponding devices are enabled for operation. The transmitter then sends the packet to the plurality of devices via the serial bus.
