Method and device for removing self-interference signal in environment using FDR mode

A method for removing a self-interference signal by a device supporting an FDR mode can further comprise the steps of: transmitting a signal to a counterpart node in a predetermined time interval; generating, in an RF stage of the device, a residual self-interference signal after removal of an analog self-interference signal with respect to the signal and then storing same; and receiving from the counterpart node an ACK/NACK signal with respect to the transmission of the signal; and determining whether or not the stored residual self-interference signal is to be used thereafter on the basis of the ACK/NACK signal.

User equipment and protocol and methods for device-to-device communication

Embodiments of a UE and methods for D2D communication are generally described herein. The UE may transmit, as part of an in-network communication session, a D2D discovery status message. The D2D discovery status message may indicate an initiation or termination of a D2D discovery operation at the UE and may indicate if the UE is announcing or monitoring as part of the D2D discovery operation. The D2D discovery operation may be at least partly for configuring a D2D communication session between the UE and one or more other UEs. The UE may transmit, as part of the D2D discovery operation, a D2D discovery signal for reception at one or more other UEs. The UE may transmit and receive D2D packets over a direct link to a second UE as part of the D2D communication session.

The present disclosure discloses a communication method, an apparatus, and a system. The communication method includes: receiving, by a base station, uplink data sent by a terminal device; decoding the uplink data; and sending, by the base station, feedback information of the uplink data. The feedback information is used to indicate a decoding status of the uplink data, and carries information about an identifier. The identifier includes an identity of the terminal device or an identifier of the uplink data. In this way, the terminal device is prevented from receiving incorrect feedback information during conflicting transmission.

Virtual network function (VNF) relocation in a software defined network (SDN)

A Network Function Virtualization (NFV) Software Defined Network (SDN) controls NFV resources consumed by Virtual Network Functions (VNFs) that support a data service. Multiple NFV Infrastructures (NFVIs) execute SDN application VNFs and SDN controller VNFs, and SDN virtual Switches (vSWs) to support the data service. The NFVIs responsively transfer SDN Key Performance Indicators (KPIs). An NFV Management and Orchestration (MANO) system processes the SDN KPIs to generate VNF control data to relocate one of the SDN VNFs. The NFV MANO system processes the VNF control data to generate and transfer NFV control data to relocate the SDN VNF. The first NFVI and the second NFVI relocate the one SDN VNF from the first NFVI to the second NFVI.
