Method and device for controlling relay transmission based on non-reproduction relay mode

摘要

The present invention discloses a method and device for controlling a relay transmission based on non-reproduction relay mode, comprising: each relay node within a service area to which a source node belongs obtaining channel status information between itself and the source node and channel status information between itself and a destination node, calculating required channel information for relay selection and feeding the required channel information back to the source node; after receiving channel information sent by the relay nodes, the source node, according to the channel information, selecting from the relay nodes a group of relay nodes with greatest feedback values in the channel information to forward information and selecting a group of relay nodes with second greatest feedback values to send interference information, selected relay nodes transmitting information to the destination node in cooperation with the source node in non-reproduction relay mode. By means of the method for controlling a relay transmission based on non-reproduction relay mode of the present invention, while greatly reducing network signaling load and computation complexity, the system secrecy capacity is ensured, the performance-to-cost ratio is high, and stronger applicability is achieved.
