Various aspects of the present disclosure generally relate to wireless communication and testing. In some aspects, a device may receive information identifying a mount orientation of a wireless communication device, wherein the mount orientation indicates an orientation of a coordinate system of the wireless communication device relative to a coordinate system of a positioner. The device may capture measurement information at each position of a set of positions of the wireless communication device, wherein the set of positions comprises positions of the wireless communication device as the wireless communication device is rotated around an axis by the positioner, and wherein the measurement information is captured based at least in part on the mount orientation. The device may provide information identifying the measurement information. Some techniques and apparatuses described herein may use the measurement information to generate a codebook for beam generation. Numerous other aspects are provided.

Beam characterization

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may communicate via a serving beam set of the UE, the serving beam set being one or more of a plurality of beams. The UE may measure another beam set in accordance with a measurement schedule configured to prioritize measurement on one or more adjacent beam sets associated with the serving beam set over one or more non-adjacent beam sets associated with the serving beam set. In some aspects, the one or more adjacent beam sets may be associated with one or more coverage areas that at least partially overlap a coverage area of the serving beam set, are adjacent to the coverage area of the serving beam set, or are associated with a measurement value that satisfies a threshold in the coverage area of the serving beam set. Numerous other aspects are provided.

Adjacent beam determination

A method of wireless communication includes receiving a first beam using a first antenna device during an occasion of a reference signal. The method further includes receiving a second beam using a second antenna device that is distinct from the first antenna device during the occasion of the reference signal. Receiving the first beam and the second beam includes inputting, to a modem, a representation of a combination of the first beam and the second beam. Receiving the first beam and the second beam further includes generating, by the modem based on the representation, a first signal associated with the first beam using a first parameter associated with the first antenna device and a second signal associated with the second beam using a second parameter associated with the second antenna device.

Receiver for processing multiple beams at a user equipment (UE) device

Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a device may determine a peak to average ratio (PAR) value for a portion of a wireless transmission. In some aspects, the device may cause, based on the PAR value, a voltage to be applied to a power amplifier of the device to cause the device to transmit the portion of the wireless transmission.

Techniques and apparatuses for peak to average ratio (PAR) based power management

Various embodiments enable a multi-SIM multi-active (MSMA) communication device to operate a power amplifier in a power saving envelope tracking mode when a first radio frequency (RF) resource is supporting data transmission to a communication network associated with a first SIM and a second RF resource is supporting a voice call in discontinuous transmission mode. A MSMA communication device processor may monitor the second RF resource supporting the voice call for silence periods, the power amplifier of the first RF resource may operate in a first power-saving mode during silence periods on the voice call, and the power amplifier of the first RF resource may operate in a second power-saving mode when the voice call on second RF resource is not in a period of silence. Periods of silence may be determined by monitoring a protocol stack of the second RF resource for silence descriptor (SID) frames scheduled for transmission.

System and methods for improving opportunistic envelope tracking in a multi-subscriber identity module (SIM) wireless communication device

A method for measuring non-linear characteristics of a power amplifier is described. A calibration waveform is calculated during a testing procedure period. Amplitude characteristics of the calibration waveform at the output of the power amplifier are measured during the testing procedure period. Phase characteristics of the calibration waveform at the output of the power amplifier are measured during the testing procedure period. Pre-distortion techniques are configured based on the amplitude characteristics and the phase characteristics to be used during a normal operation period of a transmitter.
