Abstract: A method and an apparatus for transmitting frame data between a near-end device and a remote device are provided. The method includes: generating, by the near-end device, a base frame in a user-defined frame format, wherein a PHY converting chip is built in the near-end device, the base frame includes a first number of super groups, each super group includes a second number of base groups, and each base group includes media access control (MAC) frame structure data and an interframe gap; matching duration of the MAC frame structure data and the interframe gap with an output timing sequence of the PHY converting chip; and converting the base frame into an optical fiber signal through the PHY converting chip, and sending the optical fiber signal to the remote device.

Abstract: Field programmable gate array (FPGA)-based self-adaption method and apparatus for a remote radio unit (RRU) interface protocol. The FPGA includes a type register. The method includes: an RRU loads an FPGA, the FPGA including one or more interface protocol types; the RRU accesses a baseband processing unit (BBU) by using any one of the interface protocol types; the RRU detects the current interface protocol type of the BBU; the RRU records in the type register a corresponding type identifier for the current interface protocol type; and the RRU configures the interface protocol type corresponding to the type identifier. Used for detecting and adjusting an interface protocol, ensuring the uniformity between the protocol and a peer-end device interface protocol, lowering the complexity for implementing normal communication, shortening the reconstruction time that a TD-SCDMA base station is evolved to a TD-LTE base station, and ensuring normal communication of devices in common networking.
