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.

Abstract: A dynamic AP grouping method and a dynamic AP grouping device are provided. It is able to provide services to UE in a UE-centered manner as compared with a traditional mode where the services are provided to the UE in a network-centered manner, thereby to prevent the UE from frequently acquiring a network environment, and provide the data transmission service to the UE at a low speed or in a stationary state through APGs. In addition, during the movement of the UE, it is able to transmit the services to the UE through dynamic refresh of APs in the APGs and coordination of the APs in the APG. It is able to reduce the number of handover operations made by the UE, and perform the handover operation in the APG not through a core network, thereby to reduce signaling load of a core network.

Abstract: The present application discloses a method and an apparatus for transmitting downlink data, to resolve the issue of erroneous transmission of downlink data of UE when the UE moves from an EPS network to a 5G network. The method comprises: after receiving a request message for updating a session management context of the UE, a session management function entity in embodiments of the present application determining that the UE has moved from a first network to a second network; the session management function entity notifying a user plane function entity to delete a user plane connection of the UE in the first network, and creating a user plane connection of the UE in the second network, such that the user plane function entity transmits downlink data of the UE through the newly created user plane connection. The embodiments of the present application avoid transmission of the downlink data of the UE through the user plane connection in the first network, so as to ensure accurate transmission of the downlink data of the UE, thereby further improving system performance.
