The 3GPP has introduced a new narrowband radio technology called narrowband Internet of Things (NB-IoT) in Release 13. NB-IoT was designed to support very low power consumption and low-cost devices in extreme coverage conditions. NB-IoT operates in very small bandwidth and will provide connectivity to a large number of low-data-rate devices. This article highlights some of the key features introduced...
To cope with the growing demand of mobile data in hot spot areas of wireless networks, the use of massive small cell deployments with universal frequency reuse is essential. Such an aggressive reuse of spectral resources increases the level of co-channel interference, and calls for advanced multi-cell interference coordination techniques to capitalize cell densification gains. One option to address...
We investigate the impact of dynamic offset (the relative timing difference) between the frames of a Time Division Duplex (TDD) system on system utility and expected throughput. We use computer simulation to maximize three utility functions through exhaustive search over different frame offset alternatives. We initially carry out investigation in a small three-cell system and then finally we investigate...
