There is currently a great interest in 4G wireless networks as a means to cope with the vastly increasing demands for broadband wireless services. The ITU is currently undertaking a process to specify the next generation wireless networks known as IMT-Advanced. These networks will incorporate newer technologies such as MIMO transmission and the transmission of signals from multiple coordinated base stations/access points. At the same time there has been a great interest in the deployment of very small cells known as femtocells which in the end provides the ultimate path to achieve truly high capacity networks. The wireless lab at the University of Toronto was the original proponent of autonomous infrastructure wireless networks which generalized version of femtocells which preeceded femtocells. One of the major technology candidates for IMT-Advanced is LTE-Advanced which has been submitted by the wireless operator alliance - 3GPP. However the introduction of autonomous concepts into the 3GPP proposals has lagged and much research remains to answer basic questions and determine the main algorithms. The goal of this proposal is to focus on the evolving LTE air interface and make contributions on coordinated multipoint and autonomic aspects of the network. The autonmoic features of the air interface will allow greatly simplified deployment by a mixture of network operators and users thus paving the way for organic growth of the network infrastructure and ultimately the only path to achieve truly large data rates for a large number of users.
