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: An envelope detection circuit and methods for detecting an envelope of a signal using such an envelope detection circuit. One example envelope detection circuit generally includes a first diode, a capacitive element, and a clamping circuit. The first diode has an anode coupled to an input node of the envelope detection circuit and has a cathode coupled to an output node of the envelope detection circuit. The capacitive element is coupled in shunt between the output node and a reference potential node, and the clamping circuit is coupled in shunt between the input node and the reference potential node. The clamping circuit generally includes a resistive element coupled in series with a second diode.

Abstract: Certain aspects of the present disclosure provide techniques for determining a cable loss associated with a transmission cable of an apparatus. An example method includes sending, to a radio modem of the apparatus, a request for the radio modem to use a target power when sending one or more signals to the signal compensator device for determining a cable loss associated with a transmission cable communicatively coupling the radio modem with the signal compensator device, receiving, at a signal compensator device of the apparatus, the one or more signals from the radio modem sent using the target power, and determining the cable loss associated with the transmission cable based on the one or more signals.

Abstract: This disclosure discloses various vehicle-to-everything (V2X) wireless communication processes that use switching diversity to improve coverage over that of a single transmit antenna. Switching diversity may be implemented by alternating the transmit antennas according to a certain switching pattern. A V2X device determines a pattern for alternating a plurality of antennas for transmitting data packets. The V2X device selects, based on the pattern, a first antenna of the plurality of antennas, and transmit a first packet of the data packets using the first antenna. The V2X device further select, based on the pattern, a second antenna of the plurality of antennas, and transmit a second packet of the data packets using the second antenna.
