Title: Fronthaul-Aware Design for Cloud Radio Access Networks
Abstract: The cloud radio access network (C-RAN) is an emerging paradigm for fifth generation (5G) wireless cellular networks, according to which the traditional physical layer base station (BS) transmission and reception infrastructure is virtualized using cloud computing techniques. The virtualization of wireless access also enables centralized control and management of wireless access points, which provides significant benefit from a transmission spectral efficiency perspective. In the current third generation (3G) and fourth generation (4G) cellular networks, each user, also called the user equipment or UE, is served solely by its own BS. This traditional single-cell processing paradigm, shown in Figure 3.1, suffers from considerable intercell interference, especially for cell edge users. In the C-RAN paradigm shown in Figure 3.2, as the BSs are coordinated centrally from the cloud, they can potentially transmit and receive radio signals to/from users jointly, thereby creating the possibility for interference cancellation, which can significantly improve the overall network throughput.
