Hyper Cellular Network: Control-Traffic Decoupled Radio Access Network Architecture
Hyper cellular network is a radio access network architecture based on the separation of control coverage and traffic coverage, enabling agile coverage, elastic access, and adaptive service.
A base station (BS) in traditional radio access networks (RANs) handles both the signaling control and data transmission for users in its coverage. The tight coupling of control and data transmission on a single entity makes it hard to provide flexible and energy-efficient services for RANs. To meet the increasing needs for green and elastic wireless access, new air interface architectures of cellular networks that feature signaling and data separation have been developed. Hyper cellular network architecture is one of them that aims at flexible and efficient control of small cells for throughput boosting and BS sleeping-based energy saving (NIU et al., 2012).
To realize the decoupled control-traffic coverage, separation...
