Patent ID: 8737433

Claim:
A method for clock synchronization between a first communication protocol and a second communication protocol, each of the first communication protocol and the second communication protocol comprising a protocol adaptation layer (PAL) as a higher layer and a media access control/physical (MACH/PHY) layer as a lower layer, the method comprising using a communication system configured for at least one of wired or wireless transmission to perform operations including: transmitting information from the PALs to the MAC/PHY layers for communication between the first communication protocol and the second communication protocol wherein the information is required for establishing a connection between the MAC/PHY layers; establishing a connection between the MAC/PHY layers using the transmitted information and achieving synchronization between the MAC/PHY layers; transmitting a synchronization signal from the synchronized MAC/PHY layers to each of the PALs based on the information required for establishing the connection, and storing, at each of the PALs, synchronization information at the time of receiving the synchronization signal; and transmitting synchronization information of the PAL of the first communication protocol to the PAL of the second communication protocol, and adjusting a clock of the PAL of the second communication protocol by comparing the transferred synchronization information with synchronization information of the PAL of the second communication protocol.
