Abstract
To resolve issue of poor mobile communication
signaltransmission, one of the solutions is to deploy small
base stations. However, overly dense deployment results in
interference between adjacent frequency bands, which
subsequently causes Inter-Cell interference. Furthermore,
users in the base station coverage edge can be interfered by
other base stations more easily. The traditional Inter-Cell
Interference Coordination (ICIC) mechanism lets adjacent
base stations use different frequency bands. It reduces
interference among small base stations in densely deployed
areas efficiently, and is simple to implement, yet not flexible
enough. This paper proposes Adaptive Resource Balanced
Allocation Algorithm (ARBA), which takes into account the
Quality of Service (QoS) and Channel Quality Indicator (CQI)
and calculates the weight of allocating RB according to how
many users each base station serves and the current
Guaranteed Bit Rate (GBR) to Non-GBR ratio of the base
stations. The algorithm allocates Resource Blocks (RBs)
dynamically to raise system throughput and user’s satisfaction
level. Base stations which is short of resource can hence
obtain minimum resource. The use of resource becomes
optimized and fairer.
