SMDP Approach for JRRM Analysis in Heterogeneous Networks
Source: Telecom ParisTech
In this paper, the authors study Joint Radio Resource Management (JRRM) in heterogeneous networks and they propose a way of achieving optimality. The authors consider a micro, pico or femto cell with two co-localized radio access technologies (RAT), e.g. WLAN and HSDPA. RATs are mainly characterized by the data rates they offer at a given distance of the access point (resp. base station). Dual-technology Mobile Stations (MSs) are initiating downlink packet calls in the considered cell. A network controlled joint RRM algorithm is responsible to assign MS to a RAT, while taking into account the joint spatial distribution of already accepted MS, the current load of each RAT, the location of the newly accepted packet call and its influence on the global performance.
