    摘要: Certain aspects of the present disclosure provide methods and apparatus for linear precoding in full-dimensional MIMO (FD-MIMO) systems. According to aspects, an eNB may compress a larger number of antenna elements to a smaller number of antenna ports. The eNB may use a port precoding matrix to transmit reference signals to a UE, receive feedback regarding CSI based on the reference signals, and transmit data to the UE, based on a mapping of multiple data layers and mapping of antenna ports to the physical antenna elements. Further, aspects include performing elevation beamforming by dynamically forming one or more vertical sectors based on UE feedback in the elevation domain.

    摘要: A method, a device, and a system for offloading network traffic are provided, which are applied in the field of mobile communications. An offloading device located before a Serving General Packet Radio Service Support Node (SGSN) receives a data stream of a user sent by a base station, obtains an offloading policy of the user from the offloading device and/or obtains the offloading policy of the user from a policy server, and forwards the data stream according to the offloading policy. Accordingly, the offloading device can obtain the corresponding offloading policy according to the data stream sent by a forwarding plane, send a data stream of low value, low real-time performance requirement, or low priority to the Internet or another specific networks, and send a data stream of high value, high real-time performance requirement, or high priority to high-value devices, thereby reducing the networking cost.
