Description

Communication method and device Technical Field The present application relates to the field of communications, and in particular, to a communication method and apparatus. Background The forward (fronthaul) network of base stations may include a radio frequency control unit (radio equipment control, REC), a radio frequency unit (RE), and a forward link between the REC and the RE. The forward network evolves from a common radio interface (common public radio interface, CPRI) protocol to an evolved common radio interface (ENCHANTED COMMON PUBLIC RADIO INTERFACE, eCPRI) protocol, and the rate is higher and the networking is more complex. The complexity of the forward network brings about an increase in failure rate, and the forward link failure is one of the most dominant failures of the base station equipment. A forward link failure generally refers to the REC losing contact (e.g., breaking) with the RE. RX interruption and/or TX interruption may cause a forward link failure, and abnormal communication between REC and RE. After the link between the REC and the RE is broken, the REC cannot determine whether the RE device is normal, that is, cannot determine whether the broken link is caused by a failure of the RE device, and needs to respectively remove the failure of a transmission medium (such as an optical fiber) of the forward link or the failure of the RE end.
