A WIMAX NETWORK INCORPORATING A MIMO NETWORK TO NETWORK TECHNIQUE

摘要

This invention relates to a method to implement MIMO in wireless Network to Network communications. The method is incorporated in a WIMAX architecture intended for macrocell broadband services. MIMO is realized through virtual multipath created by large scale integration of network RF terminals as virtual antenna units. The WIMAX architecture is organized into three layers: Base stations, Access points and End users. The method is deployed in communication between these layers (End users/ Access points in a MIMO-MU model and Access points/ Base stations in a MIMO-SU model). The Access points' layer therefore acts as interface between the two layers. The architecture deploys SFN-MIMO-OFDM baseband frame and uses fast link feedback between MIMO processors to enhance TDD.
