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.

Abstract: Systems, methods, apparatuses, and computer program products for signal block mapping are provided. One method includes configuring, by a network node (e.g., base station or eNB), a group of discovery signaling blocks. The method may then include mapping the discovery signaling blocks of the group onto a subframe structure, including the group information into each of the discovery signaling blocks, and transmitting the discovery signaling blocks in the subframe structure.
