The invention discloses an energy efficiency and
frequency spectrum efficiency balance method for a micro
base station super dense disposition
heterogeneous network. The method comprises steps that 1),
network model construction, network bandwidth division and
frequency spectrum use mode determination are carried out; 2), a
signal to
noise ratio obtained through association of a mobile user and a
macro base station and a
signal to
noise ratio obtained through association of the mobile user and a micro
base station are calculated; 3), a statistics averaging method is utilized to calculate association probability of the mobile user and a nearest neighbor micro base
station and an average
throughput of a downlink during association of the mobile user and the
macro base
station and the micro base
station; 4),
frequency spectrum efficiency and energy efficiency of the network are calculated; and 5), an optimization model for maximizing energy efficiency is established. The method is advantaged in that the method can be applied to a traditional
cellular network to realize stable evolution, rapid disposition in a needed macrocellular scene can be realized, network energy efficiency is maximized on the condition that minimum frequency spectrum efficiency and minimum user
throughput are satisfied, network capacity is substantially improved, and user
service quality is guaranteed.
