A collaborative transmission method realized in isomerization wireless network with cooperating relay nodes

The invention discloses a method for implementing heterogeneous and collaborative transmission in a heterogeneous wireless network by using collaborative trunk nodes; one or more collaborative trunk nodes are arranged, and each of which is provided with two set of antenna modules; a base station implements an optimized selection of proper collections of the heterogeneous and collaborative trunk nodes respectively for each destination user terminal that needs trunking, selects and determines antennas with proper number for the uplink and the downlink of each terminal, thus being convenient for acquiring self-adaptive diversity and reuse gain; the emission power of each antenna is reasonably set by comprehensively considering the transmission characteristics of the uplink and the downlink, thus ensuring the balance between the transmission performance of the first-hop link and the second-hop link and optimizing the integrative performance of the system. Based on the sufficient consideration of the existing constructions of wireless network frameworks, the invention discloses two set of antennas creatively, which are respectively used as heterogeneous trunk nodes of two-hips link transmission for implementing heterogeneous transmission, thus having the advantages of simple and convenient operation, flexibility, practicability, less investment, good effectiveness and great application generalization prospect.
