In this study, we describe the behavior of LTE over the sea and investigate the problem of radio resource block allocation in such SINR limited maritime channels. For simulations of such sea environment, we considered a network scenario of Bosphorus Strait in Istanbul, Turkey with different number of ships ferrying between two ports at a given time. After exploiting the network characteristics, we...
Using femtocell in LTE with small coverage area is considered have more effective performance than Macro BTS (eNB). However, using femtocells (HeNB) in LTE will make interference problem among femtocell (HeNB) to the Macro BTS (eNB). Femtocell is a source of interference for users who cannot access it. Therefore it is necessary for interference coordination methods among the HeNB and eNB. The methods...
This paper is aimed to show the efficiency of downlink control channel (PDCCH — Physical Downlink Control Channel) utilization in LTE networks. The dramatic challenge is related to very typical case when there is no signaling resources to assign the traffic channels for users. This problem is called blocked PDCCH. In this article we are going to show the results of simulation reflecting the LTE network...
Channel-aware scheduling is one of the advanced features introduced in the uplink of long term evolution (LTE) in order to improve the system spectral efficiency. In the uplink of LTE channel-aware scheduling is possible thanks to the transmission of sounding reference signals. In this paper the performance of frequency and time domain scheduling in LTE uplink is investigated. In particular, we focus...
