Abstract:
A synchronization technique for cloud radio access network (cloud RAN) to synchronize the cloud and remote radio units. The connection between cloud and remote radios is Ethernet and IEEE1588 is used to provide synchronization between baseband residing in the cloud and remote radios.

Claim (Index 1):
A cloud radio access network (CRAN) system comprising:\n a cloud with a baseband unit to process a received baseband signal from a remote radio unit (RRU), a transmit baseband signal for transmission to the RRU, and maintain the cloud network synchronization and time of the day using a cloud IEEE1588 (Institute of Electrical and Electronics Engineering 1588) timing; said RRU consists of a baseband unit to process said transmit baseband signal from said baseband unit in the cloud and a RRU IEEE1588 timing to maintain clock synchronization with said baseband unit in the cloud and time of the day; an asynchronous link between said RRU and at least said baseband unit in the cloud and a centralized baseband unit using at least an Ethernet packet protocol, a Serial I/O (SRio) packet protocol and a proprietary packet protocol to carry an encapsulated signal consisting of at least one of an information signal, a control signal and a synchronization signal; said information signal contains a baseband frame or packet; said baseband unit in the RRU and said baseband unit in the cloud use at least one of the time of the day and an integer number to assign at least one of a time stamp and a sequence number to said information signal that is sent to said baseband unit in the cloud and said baseband unit in the RRU respectively; said baseband unit in the RRU uses at least one of said time stamp and said sequence number assigned by said baseband unit in the cloud to store said information signal based on the order of at least one of transmitted time stamp and transmitted sequence number and then format and process for transmission over the air; said baseband unit in the cloud uses at least one of said time stamp and said sequence number assigned by said baseband unit in the RRU to store said information signal based on the order of at least one of transmitted time stamp and transmitted sequence number and then format and process.
