    Abstract: Disclosed are a method and device for determining an IP flow routing rule, wherein a technical solution of making an optimal routing rule through negotiation between a network device and a terminal is provided. The method comprises: when initiating an IFOM process, a first communication device generates a first routing rule that is different from a routing rule currently executed by a second communication device; the first communication device informs the second communication device of the first routing rule, and requests the second communication device to execute the first routing rule; and the first communication device determines, according to a message returned by the second communication device, the routing rule that is eventually executed by the second communication device.

    Abstract: Disclosed are a downlink data transmission method, equipment, and system, used for reducing the data transmission pressure of a data forward transmission interface. The method comprises: first equipment receives, by means of a forward transmission interface, data of a scheduled terminal sent by second equipment, the data of the scheduled terminal being data obtained after the second equipment performs first spatial preprocessing on baseband data of the scheduled terminal; the first equipment performs second spatial preprocessing on the data of the scheduled terminal; and the first equipment converts the data, obtained after second spatial preprocessing, into a radio-frequency signal, and sends the radio-frequency signal.

    Abstract: Disclosed are a method, device and system for switching under a bearer separation scenario, which solve the problem that there are no specific implementation solutions when a UE switches among macro eNBs or processing solutions of data transmission during the switching process, aiming at the bearer separation scenario in the existing protocol. The method of the embodiments of the present application comprises: after a source macro eNB determines that there is a need for performing a switching process of a UE, sending a switching request to each spare target macro eNB, the switching request carrying information for indicating that the UE is in a bearer-separated state and information about the local node where the UE is currently located, and/or the bearer information about the UE which is currently on the local node; and selecting a target macro eNB to switch to for the UE from the spare target macro eNBs which return switching request responses, sending the switching commands carried in the switching request responses returned from the switch target macro eNB to the UE, stopping sending data to the UE and stopping receiving data sent from the UE.

    Abstract: A reference signal mapping method and a reference signal mapping device are provided. The reference signal mapping method includes steps of: determining a position of a RE to which a CSI-RS has been mapped in accordance with an N-port reference signal pattern, N being equal to 12 or 16; and performing a resource mapping operation on the CSI-RS in accordance with the determined position of the RE. The position of the RE to which the CSI-RS has been mapped in the N-port reference signal pattern being determined in accordance with a position of the RE to which the CSI-RS has been mapped in one or more of a 2-port reference signal pattern, a 4-port reference signal pattern and an 8-port reference signal pattern. As a result, it is able to achieve the 12-port or 16-port CSI-RS mapping, thereby to achieve the 12-port or 16-port CSI-RS transmission.

    Abstract: The present application provides a channel state information (CSI) feedback and receiving method and device. The CSI feedback method by a UE comprises: determining, according to an indication of a base station, at least one CSI feedback configuration group configured by the base station, wherein each CSI feedback configuration group comprises at least one CSI feedback configuration; and upon determination of a need to report CSI, reporting, via a PUCCH or PUSCH, to the base station CSI acquired based on a first CSI feedback configuration, wherein the first CSI feedback configuration is a CSI feedback configuration determined, according to location information of a CSI feedback configuration in the most recent report or location information of a CSI feedback configuration indicated by the base station, from a corresponding CSI feedback configuration group by the UE. The present application supports independent reporting of location information and corresponding CSI, thus improving the detection performance of such information, and further supports a base station to acquire CSI corresponding to a specified CSI feedback configuration, thus enabling more flexible downlink scheduling and transmission.
