Time synchronization for wireless communications

Abstract:

Methods, systems, and devices for wireless communications are described. A first node (e.g., a user equipment (UE)) may receive a timing synchronization signal from a second node (e.g., a base station) over a cellular wireless communication link. In some aspects, the timing synchronization signal may indicate mapping information to synchronize the first node with the second node. The mapping information may be for synchronizing a first time of a first clock of the first node to a second time of a second clock of a second node. The first node may synchronize the first time of the first clock to the second time of the second clock based at least in part on the mapping information and the synchronization information. The first node may transmit a timing control based on a timing of the second clock to a device connected to the first node via a local wired interface.
