On Partial Loading for Interference Management in OFDM Cellular Networks

Interference management is a fundamental issue of a wireless network. In this paper, an interference management scheme based on partial loading is presented. The advantage of partial loading is that it does not require any protocol changes and renders an easy implementation. The partial loading scheme can be combined with other interference management techniques. In this paper, we present various partial loading schemes and evaluated their performances. These schemes divide the total channels into subgroups. By intelligently select the loading probability for each subgroup, we show that the performance, in terms of coverage and spectrum efficiency, of the network can be greatly improved. An analytical model is developed in the paper to verify the performance gains of these proposed partial loading schemes.
