Device-to-Device Communication Underlaying Cellular Communications Systems
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 of the underlay radio in a multi-cell e...
متن کاملPerformance Analysis of Device to Device Communications Overlaying/Underlaying Cellular Network
Minimizing the outage probability and maximizing throughput are two important aspects in device to device (D2D) communications, which are greatly related to each other. In this paper, first, the exact formulas of the outage probability for D2D communications underlaying or overlaying cellular network are derived which jointly experience Additive White Gaussian Noise (AWGN) and Rayleigh multipat...
متن کاملPerformance analysis of device-to-device communications underlaying cellular networks
Device-to-device (D2D) communications underlaying cellular networks are considered to be promising communication modes to improve network radio resource efficiency and provide higher transmission data rates to devices close to each other. However, when D2D communications reuse cellular resources, the resulting interference will cause significant performance loss to cellular users. In this paper...

متن کاملEnergy Efficiency Resource Allocation for Device-to-Device Communication Underlaying Cellular Networks
The energy efficiency (EE) of Device-to-Device (D2D) communication underlay cellular networks has become a significant issue because of increasing the resource utilization and extending the battery life of user equipment. However, the interference caused by sharing the same resources with the cellular users will descend the performance of the system. Therefore, D2D users should be allocated rea...
