Abstract: This application provides an optical link fault identification method, and relate to the field of communications technologies. The method includes: obtaining performance data of a network device, extracting a feature parameter of the performance data, and identifying a fault mode on an optical link based on the feature parameter. The method resolves problems of a difficulty in fault identification and slow troubleshooting that are caused by a large quantity of devices, many line faults, and a difficulty in obtaining manual troubleshooting cases. In addition, a fault can be quickly identified when the fault occurs, improving troubleshooting efficiency. When an optical link risk does not cause a fault, deterioration of the performance data can be found in advance based on a feature, to perform identification and warning.

Abstract: A base station, a small cell, and a method for scheduling a communications link resources are provided. A first small cell reports load information and channel state information of a channel between the first small cell and a neighboring second small cell to a base station. The first small cell receives link pre-scheduling signaling from the base station. The link pre-scheduling signaling includes wireless resource occupation information that indicates an occupancy of a wireless resource of the first small cell by a backhaul link. The first small cell allocates a first wireless resource in available wireless resources to the backhaul link according to the channel state information and the wireless resource occupation information, and allocates a second wireless resource in the remaining available wireless resources to an access link used for data transmission between the first small cell and a user equipment device.

Abstract: This application discloses a precoding processing method and an apparatus. The method includes: A base station determines first downlink channel information based on a pilot signal received from a terminal device. The base station receives a precoding matrix indication PMI from the terminal device, determines second downlink channel information based on the PMI, determines a precoding matrix of a downlink channel based on the first downlink channel information and second downlink channel information, and performs precoding processing by using the precoding matrix. In this method, when calculating a downlink BF weight, the base station combines the downlink channel information obtained based on the pilot signal with the precoding matrix indicated by the PMI, to compensate for a quantization error caused by feedback of a single PMI indication. This method improves accuracy of beamforming weights.
