In this article we propose to facilitate local peer-to-peer communication by a Device-to-Device (D2D) radio that operates as an underlay network to an IMT-Advanced cellular network. It is expected that local services may utilize mobile peer-to-peer communication instead of central server based communication for rich multimedia services. The main challenge(More)
In recent years WLAN technology has become the common wireless access technology for mobile computing. Additional to infrastructure access to WLAN networks, peer-topeer and mesh networking are currently gaining in interest. Mesh networking techniques using WLAN are being standardized in IEEE 802.11s. This article describes use cases, the main technical(More)
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 describes work undertaken partly in the context of the IST-2001-34157 Power aware Communications for Wireless OptiMised personal Area Network (PACWOMAN). The IST program is partially funded by the EC. Abstract--Short-range wireless systems have recently gained a lot of attention to provide seamless, multimedia communications around a(More)
In heterogeneous cellular scenarios with macrocells, femtocells or picocells users may suffer from significant co-channel cross-tier interference. To manage this interference 3GPP introduced almost blank subframe (ABSF), a subframe in which the interferer tier is not allowed to transmit data. Vulnerable users thus get a chance to be scheduled in ABSFs with(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)
