Abstract: A method for communication includes obtaining a timing signal from a timing synchronization reference source, computing a system frame number (SFN)-direct frame number (DFN) offset, creating a timing fingerprint using the timing signal and the SFN-DFN offset, the timing fingerprint also comprising additional timing information, entering the timing fingerprint into a database, continually updating the timing fingerprint, determining whether the timing signal remains within a threshold, if the timing signal exceeds the threshold, iterating the timing fingerprint, verifying the timing fingerprint to determine whether there is a timing inconsistency between a most recent timing fingerprint and current time, if the timing fingerprint is verified, using the SFN-DFN offset to derive current DFN timing to decode a sidelink control information (SCI) communication, and if the SCI communication is decoded, using the timing signal for communicating over a sidelink communication channel.

Abstract: Device-to-device operations are scheduled based on receive and transmit pools that may have a conflict in time domain. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for resolving time domain conflict in device-to-device communication are provided. The apparatus may compute a first block rate metric for a first device-to-device communication on a first frequency and a second block rate metric for a second device-to-device communication on a second frequency. The apparatus may detect a time-domain conflict between the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency. The apparatus may prioritize the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency based on the first block rate metric and the second block rate metric.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus selects a serving cell for connection to a network. The apparatus performs a search for a frequency band on a neighbor cell for use in device-to-device communications. The apparatus performs the device-to-device communications using pre-configured resources associated with the frequency band when the search for the frequency band on the neighbor cell fails. The apparatus performs the device-to-device communications using resources associated with the frequency band of the neighbor cell when the search for the frequency band on the neighbor cell is successful.
