his study investigates the uplink outage performance of-tier heterogeneous cellular networks by accounting for both truncated channel inversion power control effect and biased user association.Each user has a maximum transmit power constraint and transmits data when it has sufficient transmit power to perform channel inversion.With biased user association,users are not necessarily associated with their closest base station(BS)where a different bias factor is assigned to each network tier.Using stochastic geometry,we first derive truncation outage and signal-to-interference-plus-noise ratio(SINR)outage for each tier respectively as a function of the biased and power control parameters,and ultimately the overall out-age of network which represents the overall outage per-formances Simulations validate our analytical derivations.
