Inter-Cell Interference Coordination and Synchronization based on Location Information

Location of mobile terminals is an information which is now available in mobile cellular systems, at the mobile terminal itself but also at its serving base station. The location information is either obtained from global navigation satellite systems (GNSS) or directly from the radio access of the mobile cellular system. In this paper, using the concrete example of the 3GPP Long Term Evolution (LTE) mobile cellular system, we study two aspects of the radio communications, which can take benefit from the positioning information: the inter-cell interference coordination (ICIC) and the synchronization. Section II presents location-based ICIC, where the location information is used at the base station and section III treats synchronization, where the location information is used at the mobile terminal. The impact of positioning inaccuracy is evaluated in both sections
