Abstract:Abstract-We study the problem of channel selection of noncooperative OFDMA femtocells in two-tiered macro-femto networks. Using a physical channel model, we consider a distributed channel allocation of femtocells and a total capacity objective, which is the total capacity of uplink macro users and femto users. We assume a time-slotted system, a time-invariant channel model (no fading), each user knows the signal-to-interferenceplus-noise ratio (SINR) of all channels, and the channel selection happens only at t… Show more
