Abstract
The present invention provides a method and device for self-adapting an RRU interface protocol based on FPGA baseband unit equipment, the FPGA includes a type register, and the method includes: the RRU loads a Field Programmable Gate Array FPGA; the FPGA includes one or more Interface protocol type; the RRU uses any of the interface protocol types to access the remote radio frequency unit BBU; the RRU detects the current interface protocol type of the BBU; The corresponding type identifier is recorded in the register; the RRU configures the interface protocol type corresponding to the type identifier. The invention is used to detect and adjust the interface protocol, ensure the unification of the interface protocol with the peer device, reduce the complexity of normal communication implementation, shorten the transformation time of TD-SCDMA base station to TD-LTE base station, and ensure that the equipment in the common networking is normal communication.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for adapting an RRU interface protocol based on an FPGA basebandunit device, and a device for adapting an RRU interface protocol based on an FPGA basebandunit device. Background technique [0002] In TD-LTE (Time Division Long Term Evolution, Time Division Long Term Evolution), there is a widely used distributed structure, which is composed of BBU (Remote Radio Unit, remote radio unit) and RRU (Building Baseband Unit, indoor baseband processing unit) ) constitutes the current popular base stationsystem architecture. [0003] At present, in the process of connecting the RRU to the BBU through optical fiber according to a specific RRU interface protocol, the RRU needs to support the smooth evolution from the TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) standard to TD-LTE The requirements of the standard increase the types of RRU i...
