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

1. A method for transmitting an interface signal through an optical transport network, comprising:
mapping a plurality of Common Public Radio Interface (CPRI) signals of a distributed 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, and wherein the ODUk is mapped into the OTUk; performing electro-optic conversion on the OTUk signal to generate an optical signal; and sending the optical signal. |
