“…The backhaul between the CBS and DBS requires low latency and high data rate transmission to reflect the UE activity in a timely manner. However this increases the system overhead, which brings the question on how to design an efficient signaling mechanism between CBS and DBS [116].…”

“…A Similar approach has been followed in [7] for the global system for mobile communication (GSM). The authors of [8] argue that the control and the data channels are logically separated in current standards but they are mixed at the final stage to be transmitted by the same physical node.…”

“…Thus, [8] proposed a separation scheme for LTE-Railway by mapping all logical control channels to a single physical channel that is transmitted by the CBS, while all logical traffic channels are mapped to a single physical traffic channel handled by the DBS. Table II maps network functionalities, while Table III maps UE states and shows frame allocations of both the CBS and the DBS according to [6], [7] and [8].…”

“…Tight collaboration and excessive signalling exchange between the CBS and the DBS provide reliable, robust and updated information. However this increases the system overhead [7] and requires an ideal backhaul connection, i.e., high throughput and low latency [13]. On the other hand, a low rate CBS/DBS signalling relaxes the backhaul requirements and reduces the overhead but it may result into unreliable or outof-date information.…”

Abstract-Conventional cellular systems are designed to ensure ubiquitous coverage with an always present wireless channel irrespective of the spatial and temporal demand of service. This approach raises several problems due to the tight coupling between network and data access points, as well as the paradigm shift towards data-oriented services, heterogeneous deployments and network densification. A logical separation between control and data planes is seen as a promising solution that could overcome these issues, by providing data services under the umbrella of a coverage layer. This article presents a holistic survey of existing literature on the control-data separation architecture (CDSA) for cellular radio access networks. As a starting point, we discuss the fundamentals, concept and general structure of the CDSA. Then, we point out limitations of the conventional architecture in futuristic deployment scenarios. In addition, we present and critically discuss the work that has been done to investigate potential benefits of the CDSA, as well as its technical challenges and enabling technologies. Finally, an overview of standardisation proposals related to this research vision is provided.

“…Compared with the separation scheme of the GSM standard [7], here we differentiate the low-rate data service from the high-rate data service, which results in a distinct separation scheme of logical channels. This more fine-grained separation allows the network to ensure a basic level of data service to the mobile users, and thus is more practical.…”

Abstract-The radio access networks (RANs) need to support massive and diverse data traffic with limited spectrum and energy. To cope with this challenge, software-defined radio access network (SDRAN) architectures have been proposed to renovate the RANs. However, current researches lack the design and evaluation of network protocols. In this paper, we address this problem by presenting the protocol design and evaluation of hyper-cellular networks (HyCell), an SDRAN framework making base station (BS) operations globally resource-optimized and energy-efficient (GREEN). Specifically, we first propose a separation scheme to realize the decoupled air interface in HyCell. Then we design a BS dispatching protocol which determines and assigns the optimal BS for serving mobile users, and a BS sleeping protocol to improve the network energy efficiency. Finally, we evaluate the proposed design in our HyCell testbed. Our evaluation validates the feasibility of the proposed separation scheme, demonstrates the effectiveness of BS dispatching, and shows great potential in energy saving through BS sleeping control.
