With the increasing demand on higher data rates to enhance the user experience, one possible solution would be to extend the cellular technology such as LTE toward the unlicensed bands. Initially, LTE was designed based on the frequency re-use factor of one and which has lead to higher capacity in several deployment scenarios. This happens when LTE exclusively uses the licensed spectrum where interference...
The growing demand on data to enhance the user experience has motivated research toward increasing the efficiency of spectrum utilization by extending cellular technology such as LTE toward unlicensed bands. In order to study the effect of channel access priorities on coexistence of several LAA networks, we consider load based equipment (LBE) based MAC protocol where we use stochastic geometry to...
In fluctuating mobile environments where operators have to confront the increasing demands of their subscribers, insufficient spectrum poses capacity limitations. This work studies the gain that cooperative multicast transmission provides when used to boost the data rate in Device-to-Device (D2D) communication, enabling data sharing among users. A multicast network combines the benefits of both a...
In this paper, we introduce a scheme of caching requested data in LTE networks. After data (eg., web pages) is cached after its first request, the subsequent requests of the same data are served from the network's caching memory directly. The idea in this scheme is new in that the caching memory is at the level of the mobile devices themselves and not in the LTE core network, as in other proposed...
