Abstract: Embodiments of the present invention relate to a channel estimation method, a base station, user equipment UE, and a system. The method includes: setting up, by a base station, a connection to user equipment UE; and sending, to the UE, notification information indicating that the UE is in a radio remote scenario, where the notification information is used to instruct the UE to perform channel estimation by using a channel estimation algorithm applicable to the radio remote scenario, and the channel estimation algorithm is used to perform channel estimation on a signal that is obtained after downlink signals from multiple radio remote units RRUs are superposed. The UE can perform channel estimation by using the appropriate channel estimation algorithm, to effectively improve accuracy of the channel estimation, thereby effectively improving a downlink data throughput of the UE.

Abstract: A method and an apparatus for implementing channel measurement are disclosed in the present invention. The method includes: determining an antenna port subset, which is required to be measured, for a UE according to current state information of the user equipment UE; and informing the UE to perform channel measurement for the subset of antenna ports that is required to be measured and feed back channel state information. Through the present invention, when the state information of the UE meets a certain condition, the UE measures only the reference signals of a part of antenna ports, and feeds back channel state information for this part of antenna ports. Therefore, the overhead generated by the feedback of the UE to the channel state information is reduced.

Abstract: The technology of this application relates to a communication method, apparatus, and system, and relates to the field of communication technologies. The method includes a first node performing data transmission with a destination node based on a first communication link, where the first communication link includes a second node. When the first communication link is unavailable, the first node performs data transmission with the destination node based on a second communication link, where the second communication link includes a third node different from the second node, and the second node and the third node belong to a destination node group. The second communication link serves as a redundant communication link of the first communication link, to provide communication support between the first node and the destination node for data transmission when the first communication link is unavailable, so as to improve communication reliability of a system.
