FPGA-BASED SELF-ADAPTION METHOD AND APPARATUS FOR REMOTE RADIO UNIT (RRU) INTERFACE PROTOCOL

摘要

A field programmable gate array (FPGA)-based self-adaption method and apparatus for a remote radio unit (RRU) interface protocol. The FPGA comprises a type register. The method comprises: an RRU loads an FPGA, the FPGA comprising 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. The present application is 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.
