Abstract: Aspects directed towards synchronizing out of coverage (OOC) vehicle-to- everything (V2X) communications are disclosed. In one example, a scheduled entity detects a loss of a synchronization signal associated with a V2X communication by detecting when a timing uncertainty value or error value is greater than a threshold value. Packet timing information is then received in response to the loss of the synchronization signal from at least one user equipment (UE) synchronized with the synchronization signal. The scheduled entity then maintains the V2X communication by performing a timing adjustment based on the packet timing information.

Abstract: A method of wireless communication, by a user equipment (UE), includes computing a transmit power at a first port in response to a received forward detected power measured at a third port. The method also includes computing a return loss of an antenna at a second port in response to a received reflection value measured at a fourth port. The method further includes estimating a cable loss based on a difference between a device output power and the computed transmit power at the first port. The method also includes adjusting a transmit power at the second port according to the estimated cable loss and/or the computed return loss.

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.
