… While our study applies to OFDMA femtocells in general, our measurements are conducted
on a WiMAX (802.16e [17]) femtocell testbed. WiMAX divides the spectrum into multiple …

… As shown in Figure 1, we consider a two-tier OFDMA network where … femtocells, that is, the
subchannel assignment to femto users and the power allocation on subchannels in femtocells…

… OFDMA subchannels is necessary. Such an approach would help to enhance frequency reuse
in the femtocells … 5 illustrate how interference can be avoided in OFDMA femtocells while …

… In the following, we provide an overview of the different approaches for interference mitigation
in two-tier OFDMA femtocell networks. These approaches consider uplink and/or downlink …
