A method, an apparatus, and a computer program product for wireless communication are provided in connection with enabling timing source selection and deselection in a decentralized manner for distributed D2D synchronization in densely populated communications systems. In an example, a communications device, functioning in a non-timing source (TS) mode, is equipped to receive a request for timing information during a synchronization channel. The communications device may further be equipped to determine whether to switch to a TS mode based on a selection utility metric value. In another example, a communications device, functioning in a TS mode, is equipped to transmit a TIB during a synchronization channel, and determine whether to switch to a non-TS mode based on a deselection utility metric value. In the TS mode, the UE is configured to transmit a TIB, while in the non-TS mode the UE is configured not to transmit the TIB.

Method and apparatus for timing source selection and deselection distributed device to device synchronization

A method, an apparatus, and a computer program product for wireless communication are provided in connection with improving resource allocation for distributed D2D synchronization in densely populated communications systems. In an example, a communications device is equipped to transmit a synchronization signal during a beacon period of a synchronization channel. In an aspect, the synchronization channel may include the beacon period, a paging period, and a TIB period. The communications device may further be equipped to monitor at least one of the beacon period, the paging period, or the TIB period of the synchronization channel for one or more signals from one or more UEs in a D2D network, and determine whether to transmit information during at least one of the beacon period, the paging period, or the TIB period based at least in part on the monitoring.
