Utilizing the Inherent Properties of Preamble Sequences for Load Balancing in Cellular Networks
Achieving maximum network throughput while providing fairness is one of the key challenges in wireless cellular networks. This goal is typically met when the load of Base Stations (BSs) is balanced. In a recent study, it was confirmed that the preamble sequence, which is mainly used for cell identification and synchronization, can be used as an implicit load indicator for long term load balancing in cellular networks. In this paper, the authors further explore its viability as an implicit information indicator, and present distributed load balancing schemes based on the properties of the preamble sequence. These schemes empower the Mobile Stations (MSs) to implicitly obtain information about the load status of BSs for intelligent cell-site selection.
