Abstract
Wireless networks of next generation will satisfy the user demand for a ubiquitous mobile broadband access. Current research efforts are targeting therefore at the efficient realization of a flexible radio interface and network architecture. The wide range of application scenarios seems to prohibit a “one radio interface fits all” solution. Instead, it requires a multitude of solutions tailored for specific communication environments. Ideally, these solutions are related radio interface modes that have a common technology basis. This article presents a protocol reference architecture that enables the efficient integration of multiple such modes in a complementary way. This architecture essentially benefits from the commonalities between these modes. Hence it facilitates the coexistence and the cooperation of different modes in all devices of a future relay-based radio access network: (i) user terminals, (ii) access points and (iii) relay nodes. This article focuses on the realization of multi-mode capability of user and control planes and the related management of the protocols of a flexible radio interface. A proof of concept and its evaluation are presented at the example of relay-based 4G broadband networks and IEEE 802.16 (WiMAX).
