METHOD FOR APPROXIMATING AND OPTIMIZING GAINS IN CAPACITY AND COVERAGE RESULTING FROM DEPLOYMENT OF MULTI-ANTENNAS IN CELLULAR RADIO NETWORKS

摘要

PROBLEM TO BE SOLVED: To provide a method for planning and optimizing the configuration of a radio access network which comprises base stations and receivers and employs a mobile radio technology that allows and/or enforces use of multi-antenna types at the base stations and receivers.;SOLUTION: By a ray tracing algorithm which is performed between transmitter positions and receiver positions using a 3D clutter height matrix, a scalar metric is determined for each receiver position which directly reflects a capacity gain resulting from applying a multi-antenna type instead of a single antenna at the transmitter and receiver positions. This scalar metric allows in an algorithmically advantageous way to analyze the relative performance of different MIMO antenna types in a potential deployment area and to select an optimal MIMO antenna type for a particular coverage sector.;COPYRIGHT: (C)2011,JPO&INPIT
