Abstract:
3gPP Long Term Evolution (LTE) Advanced and Wireless Local Area Networks (WLAN) are both striding towards the 5th generation wireless networks; networks characterized by guaranteed cell edge coverage and performance. To do this, networks will have unprecedented density of deployed cells, which will actively work with each other to maximize the link to all possible User Equipments (UEs). In this article, we propose a method by which individual network nodes can use additional antennae so as to transmit data to individual UEs while limiting the interference seen by other UEs on the same frequency and time-slot. Ideally, we should be able to have a dense network of nodes, all transmitting simultaneously on the same resource, without any cross-interference. We show that our proposed algorithm shows substantial performance gains over existing techniques addressing coordinated multipoint transmission between multiple transmitters and receivers.
