Abstract
A method for reducing interference from a wireless communications system. The interference threshold is set based on a quality criterion that can be measured during operation of the system. The quality criterion is measured during system operation. Preferably, a separate quality criterion measurement is performed for each of an uplink and a downlink of the wireless communications system. The quality criterion is compared to the information containing the set interference threshold. A breach of the interference threshold for the uplink or the downlink is determined when the measurement indicates that the measured quality criterion is sufficiently poor that operation of the system should be modified. Upon determination of an interference breach in either the uplink or downlink, the system initiates an asymmetric enhanced mode operation in which redundant data transmission is established over the link exhibiting the interference breach, while standard, non-redundant transmission continues on the other link.
