Abstract

Systems and methods of cell selection are based on measures of frequency selectivity, time selectivity, and/or antenna selectivity. For example, the delay spread and coherence bandwidth of a channel are two measures of frequency selectivity that can be taken into account in the cell selection process. In addition to or instead of either delay spread or coherence bandwidth, Doppler frequency shift or coherence time (which are two measures of time selectivity) and/or antenna correlation or mean signal strength per antenna (which are two measures of antenna selectivity), among other parameters, can be determined and taken into account.
