Optimizing User Association and Spectrum Allocation in HetNets: A Utility Perspective

  title={Optimizing User Association and Spectrum Allocation in HetNets: A Utility Perspective},
  author={Yicheng Lin and Wei Bao and Wei Yu and Ben Liang},
  journal={IEEE Journal on Selected Areas in Communications},
The joint user association and spectrum allocation problem is studied for multi-tier heterogeneous networks (HetNets) in both downlink and uplink in the interference-limited regime. Users are associated with base-stations (BSs) based on the biased downlink received power. Spectrum is either shared or orthogonally partitioned among the tiers. This paper models the placement of BSs in different tiers as spatial point processes and adopts stochastic geometry to derive the theoretical mean… CONTINUE READING
