Synchronization and master information block for off grid radio service

Abstract:

This disclosure relates to techniques for supporting narrowband device-to-device (D2D) wireless communication, including possible techniques for providing synchronization and master information block signals in an off grid radio system. A wireless device may provide D2D synchronization signals for a D2D communication group. The D2D synchronization signals may be provided using multiple frequency channels. The D2D synchronization signals may be provided on each respective frequency channel of the frequency channels during a respective portion of a D2D synchronization signal cycle in a sequential manner.
