Abstract
A correct escape mechanism is determined according to interference type. Transmission is arranged so that interference may be measured at all time slots as needed to compute a measure of variance in interference in time slots. If the variance is above a predetermined value, time division duplex escape mechanisms are employed. If the variance is below a predetermined value, appropriate escape mechanisms are employed depending on whether the escape mechanism is being implemented during an uplink or downlink. Interference causing FDD WTUs may be handed over to carrier bands to control interference experienced by TDD users.
