Synchronization of a peer-to-peer communication network

Abstract

In an ad hoc peer-to-peer communications network, timing synchronization is facilitated between two or more nodes. A node can establish an original symbol timing and receive a first timing synchronization symbol from a peer node. A timing adjustment can be calculated based in part on the first timing synchronization symbol. An adjusted symbol timing can be established by adjusting the first symbol timing by the calculated timing adjustment amount. The adjusted symbol timing can be conveyed to one or more peer nodes, in order to facilitate timing synchronization among the nodes.

Description

technical field [0001] In general, the following description relates to wireless communications, and in particular, the following description relates to synchronization in ad hoc peer-to-peer networks. Background technique [0002] Wireless communication systems are widely deployed today to provide various types of communication; for example, voice and / or data may be provided over such wireless communication systems. A typical wireless communication system or network may provide multiple users with access to one or more shared resources. For example, a system may use various multiple access methods such as Frequency Division Multiplexing (FDM), Time Division Multiplexing (TDM), Code Division Multiplexing (CDM), Orthogonal Frequency Division Multiplexing (OFDM), etc. into technology. [0003] Wireless communication networks are commonly used to transmit information regardless of where a user is located (inside or outside a certain building) and whether the user is stationar...

Problems solved by technology

However, if there are timing differences or timing offsets between two or more devices, this can cause problems and further synchronization between these devices is required
