Résumé
Device-to-device (D2D) communication has been recently proposed as an important technology
for the next-generation wireless cellular system, which promises to significantly improve
the system spectrum-efficiency, and energy-efficiency by exploiting the advantages of
proximity communication. However, many challenges must be resolved to enable efficient
integration of D2D communication into the cellular networks. The overall objective of this
doctoral research is to develop novel and efficient resource allocation algorithms for D2D
communications.
Toward this end, we investigate three key design issues to support the harmonious coexistence
of D2D and existing cellular communications, namely spectrum and energy-efficient
resource allocation for single hop D2D communication, mode selection and resource allocation
for relay-based D2D communication, and joint scheduling and resource allocation for
D2D communication. These designs have resulted in several novel contributions, which can
be summarized as follows.
First, we propose the spectrum-efficient resource allocation design for single hop D2D
communication in the cellular networks, which is presented in Chapter 5. In particular, we
present a resource allocation model which allows dynamic power allocation and subchannel
assignment for both cellular and D2D links. It is then demonstrated that the proposed algorithm
can improve the system spectrum-efficiency significantly in comparison with existing
D2D resource allocation algorithms.
Second, we develop a general energy-efficient resource allocation framework for single hop
D2D communication in cellular networks which targets to maximize the minimum weighted
energy-efficiency (EE) of D2D links while maintaining the minimum required data rates of
the cellular links. The research outcomes of this study are presented in Chapter 6. Particularly,
we propose a low-complexity power control and subchannel allocation algorithm, which
can approach the optimal solution of the underlying resource allocation problem. We also
present the distributed implementation for the proposed algorithm, which helps reduce the
computation burden for the BS.
Third, we study the resource allocation problem for relay-based D2D communications,
which is covered in Chapter 7. The proposed design allows D2D links to dynamically choose
either the direct or relay mode. We then propose an efficient mode selection and resource allocation
algorithm which optimizes the system spectrum-efficiency. We show that the proposed
algorithm can dramatically outperform the conventional resource allocation schemes. Finally, we consider the joint scheduling and resource allocation design for D2D communication
in the cellular networks, which is described in Chapter 8. The proposed design
framework allows to dynamically select the set of scheduled D2D links and optimize the system
spectrum-efficiency. Toward this end, we develop a monotonic-based algorithm which
asymptotically achieves the optimal solution. We then propose a low-complexity algorithm,
which can perform much better than the conventional ones and approach the optimal solution.
