The disclosures provide a method and apparatus for transmitting and receiving interface signals of a distributed base station. At least one channel of Common Public Radio Interface (CPRI) signals of a distributed base station are encapsulated into optical transport unit x (OTUx) signals in a frame structure of OTUx by adopting Generic Mapping Procedure (GMP) mapping scheme, wherein the x represents a transmission capacity and wherein the OTUx is adopted for providing a bandwidth required by the at least one channel of CPRI signals, and then the OTUx signals that bear the at least one channel of CPRI signals are sent.

Method and apparatus for transmitting and receiving interface signals of distributed base station

Signal transmission processing method and apparatus and distributed base station

A signal transmission processing method and apparatus and a distributed base station are provided according to the embodiments of the present invention. The distributed base station includes a Base Band Unit (BBU) and a Remote Radio Unit (RRU). A transmitting end connected to one of the BBU and the RRU receives at least one of interface signals from the one connected thereto, performs optical transport network (OTN) electrical layer multiplexing to obtain OTN signal frames and transmit optical signals including the OTN frames to a receiving end connected to the other of the BBU and the RRU. The receiving end performs frame processing for the OTN frames received from the transmitting end to obtain the interface signals, and transmit the interface signals to the other connected thereto.
