Dense deployment of small cells is seen as one of the major approaches for addressing the traffic demands in next-generation wireless networks. However, dense deployment of large number of small cells necessitates effective techniques for placing under-loaded small cells into sleep mode, so as to save energy. Such techniques should be low complexity and should not also compromise quality of service...
Large-scale multi-cell multi-user multiple-input multiple-output (MU-MIMO) is expected to be one of the enabling technologies for fifth generation (5G) time division duplexing (TDD) systems. One of the major challenges faced by this technology is the pilot contamination issue where interference from users in the neighboring cells may significantly impact the performance of the channel estimation process...
The fifth-generation (5G) mobile communication systems will benefit immensely with the extension of their operation to mmWave bands. To this end, understanding the system-level performance of mmWave cellular networks carries critical importance. In this paper, we investigate the average signal-to-interference plus noise ratio (SINR) distribution (geometry) performance for indoor and outdoor mobile...
