Abstract
The Long Term Evolution-Advanced (LTE-A) networks are being developed
to provide mobile broadband services for the fourth generation (4G) cellular
wireless systems. Device-to-Device (D2D) communications is a promising
technique to provide wireless peer-to-peer communication services and
enhance resource utilization, as well as spectrum efficiency. In this thesis,
a centralized resource allocation scheme involving several Device-to-Device
(D2D) broadcast groups underlaying cellular network is proposed. The great
amount of interference caused by sharing the resources between different
D2D broadcast users may significantly affect the performances of other D2D
users. Therefore, an efficient resource allocation method is necessary to coordinate
the interference. Specifically, we formulate the interference relationships
among different D2D broadcast groups as an innovative interferenceaware
graph. We propose a centralized interference-aware graph based resource
allocation algorithm that can effectively minimize the interfered D2D
users between different D2D broadcast groups. This scheme aims to optimize
the throughput of D2D communications over the shared uplink spectrum
meanwhile mitigate different D2D broadcast groups from affecting the performances
of each other. Moreover,a distributed algorithm is proposed based on some modifications of the centralized one.
