Heterogeneous network (HetNet) is a promising concept for increasing capacity and alleviating spectrum scarcity. In HetNets, however, channel assignment and transmit power control affect the distribution of users among base stations. We present a novel scheme to maximize the uplink sum rate in twotier HetNets with one macrocell and several femtocells, where the transmit power of each user is bounded and at least one channel is assigned to each user. We divide the problem into two sub-problems…

Joint User Association and Power Control for Load Balancing in Downlink Heterogeneous Cellular Networks
The proposed strategies have a superior performance than the conventional association, and the second association strategy achieves a higher load balancing gain and energy efficiency than conventional scheme and other offloading strategies.
Optimizing User Association and Spectrum Allocation in HetNets: A Utility Perspective
By formulating and solving the network utility maximization problem, the optimal user association bias factors and spectrum partition ratios are analytically obtained for the multi-tier network and it is revealed that the downlink and uplink user associations do not have to be symmetric.
Energy Efficient User Association and Power Control for Dense Heterogeneous Networks
Numerical results demonstrate that the proposed heuristic user association scheme and power control algorithm can improve the average energy efficiency of all the users dramatically.
Uplink rate distribution in heterogeneous cellular networks with power control and load balancing
A tractable and general model is proposed to characterize the uplink SIR and rate distribution in a K-tier HCN as a function of the association and power control parameters and it is shown that the optimal degree of channel inversion increases with load imbalance in the network.
Energy Efficiency Evaluation of Multi-Tier Cellular Uplink Transmission Under Maximum Power Constraint
Assessment of the energy efficiency of uplink transmission in heterogeneous cellular networks (HetNets), where fractional power control is applied at user equipments (UEs) subject to a maximum transmit power constraint, reveals that, for UE whose path loss is below the transfer path loss, its energy efficiency highly depends on the value of power control coefficient adopted by FPC.
On Stochastic Geometry Modeling of Cellular Uplink Transmission With Truncated Channel Inversion Power Control
Using stochastic geometry, a tractable uplink modeling paradigm for outage probability and spectral efficiency in both single and multi-tier cellular wireless networks is developed and approximate yet accurate simple expressions are obtained, which reduce to closed forms in some special cases.
Joint Access Point Selection and Power Allocation for Uplink Wireless Networks
A novel algorithm named Joint Access Point Selection and Power Allocation (JASPA) and its various extensions that allow the users to efficiently optimize their rates are presented.
Joint Downlink and Uplink Aware Cell Association in HetNets With QoS Provisioning
This paper addresses a joint downlink and uplink aware cell association problem in a multi-tier heterogeneous network in which base stations (BSs) have finite number of resource blocks (RBs) to
Uplink capacity and interference avoidance for two-tier femtocell networks
An uplink capacity analysis and interference avoidance strategy in such a two-tier CDMA network is developed and results reveal that interference avoidance through a time-hopped CDMA physical layer and sectorized antennas allows about a 7x higher femtocell density, relative to a split spectrum two- tier network with omnidirectional fem tocell antennas.
Joint Resource Partitioning and Offloading in Heterogeneous Cellular Networks
It is shown that load balancing is insufficient, and resource partitioning is required in conjunction with offloading to improve the rate of cell edge users in co-channel heterogeneous networks.
