Abstract: A method includes determining a first transmission power for a first transmission from a user equipment and a second transmission power for a second transmission from the user equipment, the first and second transmission at least partially overlapping, the first and second transmission power being selected in dependence on at least one of which one or more channels are being transmitted and information on the at least one or more channels.

Abstract: The example and non-limiting embodiments relate generally to synchronization and, more particularly, to a sidelink synchronization procedure. Exemplified embodiments are provided that may include determining a new synchronization source by a source user equipment, where the source user equipment is configured to provide synchronization to at least one receiving user equipment with use of a sidelink. The exemplified embodiments may further include transmitting by the source user equipment to the at least one receiving user equipment an indication that the source user equipment will update from a current synchronization source to the new synchronization source. The exemplified embodiments may further include transmitting synchronization signals and control signals from the source user equipment to the at least one receiving user equipment using an updated reference frequency corresponding to use of the new synchronization source by the source user equipment.
