In this article, based on the overview of network coupling structure between radio access technologies, the concept of joint radio resource management built onto the reference structure is introduced. In order to optimize usage of radio resource and jointly designed from the user perspective, a joint scheduling mechanism allowing traffic to be split over a tightly coupled radio network supported by an adaptive radio multihoming approach is deliberately discussed. With respect to the time-division access scheme in HIPERLAN/2, which is selected as one example of WLAN, algorithms and performance of traffic scheduling in such a radio access technology are given. The required synchronization scheme supporting traffic splitting is also introduced.read more

A separate-SMDP approximation technique for RRM in heterogeneous wireless networks
TL;DR: The proposed separate-SMDP model approximates the original complex SMDP linear programming (LP) problem by building a series of simple SMDP LP problems, which greatly decreases the computational complexity of SMDP and solves its dimensionality problem.

Radio resource management for cooperative wireless communication systems with organized beam-hopping techniques
TL;DR: The proposed RRM mechanism enhances the robustness of the CWCS, based on the OBH technique working with fast temporal-spatial variant traffic, and shows that the system performance can be further improved by hybrid transmission and event- driven access management techniques.

Performance evaluation of softer vertical handovers in multiuser heterogeneous wireless networks
TL;DR: Results demonstrate that SRVHs are useful to allow finer granularity in resource allocation when there is coordination among RATs, although they fail to provide throughput improvements if they are selfishly performed by mobile terminals.
