Heterogeneous Network (HetNet) deployments are one of the key enablers in providing ubiquitous coverage and capacity enhancements for LTE-Advanced networks. They play an important role in achieving high data rate and Quality of Service requirements defined for next generation wireless networks. In this paper we evaluate various cell discovery techniques(More)
This paper presents the design of VoIP optimized packet scheduler and performance simulations for supporting voice services over downlink evolved UTRA. An efficient packet scheduler taking into account the traffic characteristics and adopting optimal resource allocation is proposed. Results are given for different control channel number settings and packet(More)
Direct device-to-device (D2D) communications is regarded as a promising technology to provide low-power, high-data rate and low-latency services between end-users in the future 5G networks. However, it may not always be feasible to provide low-latency reliable communication between end-users due to the nature of mobility. For instance, the latency could be(More)
We calculate the optimal muting ratio for time domain Enhanced Inter-Cell Interference Coordination (TDM eICIC) in a downlink HetNet scenario, consisting of macrocell and femtocell users. First we derive analytically the optimal muting ratio in a simplified scenario, and identify a particular case where all macro users are either strongly or not at all(More)
— METIS is the EU flagship project with the purpose of developing a 5G system concept that meets the requirements of the beyond-2020 connected information society and emerging applications. Within METIS project, horizontal topics (HTs) is used to build the overall system concept. Direct Device-to-Device (D2D) communication is one of the HTs and regarded as(More)
