1. A method for transmitting an interface signal of a base station, the method comprising:
- mapping, by a processor, at least one interface signals of the base station into an optical data unit k (ODUk) payload area of an optical transport unit k (OTUk) signal, wherein the k represents a transmission capacity of the OTUk signal, wherein the ODUk payload area is part of an ODUk, the ODUk is mapped into the OTUk; and
sending the OTUk signal.

Abstract
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.

5. A signal transmission processing method comprising:
-
obtaining, at a transmitting end, at least one channel of interface signals of a distributed base station from one of a base band unit (BBU) and a remote radio unit (RRU) of the distributed base station; performing, at the transmitting end, optical transport network (OTN) electrical layer multiplexing for the obtained at least one channel of interface signals of the distributed base station by encapsulating the obtained at least one channel of interface signals of the distributed base station into OTN signal frames; and performing, at the transmitting end, electro-optic conversion for the OTN signal frames to generate a channel of optical signals and transmitting the optical signals from the transmitting end to a receiving end connected to the other of the BBU and the RRU. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. An apparatus for transmitting a signal of a base station, the apparatus comprising:
-
a processor and a non-transitory computer readable medium having a plurality of computer executable instructions stored thereon which, when executed by the processor, cause the processor to map at least one interface signal of the base station into an optical data unit k (ODUk) payload area of an optical transport unit k (OTUk) signal, wherein k represents a transmission capacity of the OTUk signal, the ODUk payload area is part of an ODUk and the ODUk is mapped into the OTUk; and a transmitter configured to send the OTUk signal. - View Dependent Claims (14, 15, 16)
