Abstract
One of the main purpose for heterogeneous networks (HetNet) is to reduce the power consumption for various spectrum allocation schemes. Large-scale user behavior in a two-tier HetNet is considered for the energy-efficient spectrum allocation, which characterizes the macro BSs that guarantee traffic requirements in non-hotspot regions and micro BSs that guarantee traffic requirements in hotspot regions. Two hybrid bandwidth allocation schemes are presented for the shared/orthogonal frequency band and the high/low frequency band, where the large-scale user behavior is taken into account. We present closed-form formulas of bandwidth allocation schemes which establish the quantitative relationship between the large-scale user behavior and bandwidth allocation strategy. Both theoretical and simulation results show that the proposed schemes are effective in guaranteeing both the demands of the large-scale user behavior and keeping low power consumption.
