On channel definitions and rules for continuous dynamic channel selection in coexistence etiquettes for radio systems

Dynamic spectrum sharing between uncoordinated systems of the same kind or even between systems using different technologies is attracting an increasing interest. Closely related is also “bandwidth on demand” for different services within a system. Traditional frequency planning is more difficult and less spectrum efficient the smaller the cells become. For indoor cells the practical planning limit is definitely passed. Continuous or instant dynamic sharing makes it possible to avoid to plan the channel assignments within a system and between systems. This paper presents analysis and simulations on dynamic spectrum sharing
