发明名称 Wired/wireless converged MAC adaptor and method of transmitting frame using wired/wireless converged MAC adaptor
摘要 A wired/wireless converged media access control (MAC) adaptor and a method for transmitting a frame using the same. The wired/wireless converged MAC adaptor may include a service network interface (SNI) to transmit a MAC frame corresponding to a wired or wireless service, or common public radio interface (CPRI) data, a frame conversion unit to convert, into an orthogonal frequency division multiplexing (OFDM) frame, a wired/wireless converged MAC frame having a common frame structure of the MAC frame corresponding to the wired or wireless service or the CPRI data, and an OFDM interface configured to transmit the OFDM frame to an optical OFDM modem by dynamically allocating sub-carriers based on data transmission characteristics.

主权项 1. A wired/wireless converged media access control (MAC) adaptor comprising: a service network interface (SNI) to transmit a MAC frame corresponding to a wired or wireless service, or common public radio interface (CPRI) data; a frame conversion unit to convert a wired/wireless converged MAC frame comprising a common frame structure of the MAC frame or the CPRI data, into an orthogonal frequency division multiplexing (OFDM) frame; and an OFDM interface to transmit the OFDM frame to an optical OFDM modem by dynamically allocating sub-carriers based on data transmission characteristics, wherein the frame conversion unit comprises: a first frame conversion unit to convert the MAC frame or the CPRI data into the wired/wireless converged MAC frame, using an overhead including at least one of payload length information, sub-carrier information, OFDM interface port information, type information of a frame inputted, and error correction information; an information extracting unit to extract sub-carrier information for transmitting the OFDM frame from the wired/wireless converged MAC frame; or a second frame conversion unit to convert the wired/wireless converged MAC frame into the OFDM frame including the sub-carrier information.
