Abstract: The present disclosure relates to methods for determining a precoding matrix indicator, user equipment, and base stations. One example method includes sending a first reference signal set to user equipment, where the first reference signal set is associated with a user equipment-specific matrix set, and receiving a precoding matrix indicator (PMI) sent by the user equipment, where the PMI is used for indicating a precoding matrix that is selected based on the first reference signal set by the user equipment.

Abstract: A virtual network function (VNF) audit method and apparatus, used to audit a VNF generated by a platform that includes an authentication and authorization component, a service component, and a virtualized infrastructure. The method includes receiving an event reported by the authentication and authorization component, receiving an event reported by the service component, and receiving an event reported by the virtualized infrastructure, obtaining an event occurrence sequence of each VNF according to all received events, and auditing the event occurrence sequence of each VNF to obtain an audit result of the VNF. According to the method, the events that are distributed in different components are integrated into one event occurrence sequence in order to visually and quickly detect a malicious VNF generated by bypassing a component, and more comprehensively detect the malicious VNF, thereby reducing a missed detection rate of a VNF operation audit.

Abstract: A method for virtual carrier aggregation, a base station, and a user equipment are provided. A base station receives measurement capability indication information and indication information indicating a capability of receiving data transmission that are reported by a UE. The base station selects a measurement set for the UE according to the measurement capability indication information, and sends the measurement set to the UE, where the indication information indicating the capability of receiving data transmission includes information of carriers on which the UE supports concurrent receiving of data transmission and the measurement capability indication information includes indication information indicating a capability of the UE for measuring CSI and/or indication information indicating a capability of the UE for measuring RSRP. The base station can flexibly select an activated carrier set for the UE.
