Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a trigger event associated with a satellite communication link, the trigger event being based at least in part on at least one of: a status of an access link associated with the UE, or information associated with another device or a component of the UE. The UE may transmit a communication via the satellite communication link based at least in part on detecting the trigger event. Numerous other aspects are described.

Abstract: Aspects described herein include devices and methods for facilitating digital predistortion calibration. One aspect includes selecting a first transmission element from a plurality of transmission elements associated with a first antenna element of a plurality of antenna elements in an antenna array of the millimeter wave communication device, wherein the first transmission element is selected based on a gain setting for the first transmission element, selecting a reference transmission power for a test transmission from the first transmission element as part of a path searching operation of the millimeter wave communication device, determining a selected receive element of the plurality of receive elements based on a near field power measurement of the reference transmission power from the first transmission element using the selected receive element and a set of selection criteria, and setting a digital predistortion calibration setting using the reference transmission power and the near field power measurement.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless communications device detects a trigger to communicate via non-terrestrial network (NTN) connectivity, determines whether one or more obstructions are estimated to be blocking a subset of NTN space vehicles of a set of NTN space vehicles expected to be in view of the wireless communications device at a current location of the wireless communications device, and transmits, in response to a determination that the one or more obstructions are estimated to be blocking the subset of NTN space vehicles, at least one message towards at least one NTN space vehicle of the set of NTN space vehicles other than the subset of NTN space vehicles.

Abstract: In some implementations, a mobile device may determine a set of target orientations of the mobile device in which an antenna lobe of the mobile device is pointed toward the satellite, the set of target orientations based on: an orientation of the antenna lobe relative to the mobile device, and a location of the satellite relative to the mobile device. The mobile device may determine a current orientation of the mobile device. The mobile device may provide, at a user interface (UI) of the mobile device, guidance for rotating the mobile device from the current orientation to an orientation within the set of target orientations.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a transmitting wireless device, such as a user equipment or a base station, may apply a first set of digital pre-distortion (DPD) coefficients to a plurality of antenna elements to form a first transmit beam. The wireless device may determine to switch from using the first transmit beam to using a second transmit beam that is different from the first transmit beam and may apply a second set of DPD coefficients to the plurality of antenna elements to form the second transmit beam, where the second set of DPD coefficients is different from the first set of DPD coefficients. The wireless device may transmit signaling using the second transmit beam based at least in part on applying the second set of DPD coefficients.

Abstract: Phase variations between a transmitter (TX) waveform and a receiver (RX) waveform produced by a TX Phase-Locked-Loop (PLL) and a RX PLL, respectively, is a source of error in processing delay calibration used, e.g., in Round Trip Time (RTT) estimation. While a TX waveform and a RX waveform have a constant phase delay while in steady state conditions, during transient times, e.g., at start up or reset, the phase delay may vary by as much as ±180°, which at baseband frequencies of 50 MHz, introduces a random delay variations of as much as ±10 nsec, which is undesirable for fine position estimation using RTT. The phase delay variation between the TX waveform and RX waveform may be reduced or eliminated using a phase correction signal generated using the output signals of the TX PLL and RX PLL.

Abstract: Some techniques and apparatuses described herein protect components of a user equipment (UE), such as a low noise amplifier (LNA), from internal interference. For example, the LNA may be disconnected from a receive chain during periods of high internal interference, and may be reconnected to the receive chain during periods of low internal interference. Furthermore, some techniques and apparatuses described herein improve performance by adjusting operations of the UE to account for and/or offset increased internal interference due to a receive chain that does not include a surface acoustic wave (SAW) filter to remove unwanted radio frequency signals. For example, one or more operations of a baseband processor may be modified to account for the increased internal interference. Additionally, or alternatively, reporting of channel state information may be modified to account for increased internal interference of the UE. Additional details are described herein.

Abstract: An method for wireless communication increases efficiency of its power amplifier (PA) by reducing an insertion loss of a filter (e.g., a transmit (Tx) filter). The method includes detecting, at a user equipment, a dominant spatial direction of interference. The method further includes determining whether to bypass a transmit filter based on an energy level associated with the dominant spatial direction of the interference.

The method further includes determining transmission information based at least in part on the RF exposure budget and the size of the payload. The method further includes outputting the transmission information for a user of the wireless device.
