Abstract
A method and apparatus for providing handover between carriers of different duplex frequency separation distances is provided. A mobile terminal is configured to operate in both fixed and variable duplex. The ability operate with unpaired up-link and down-link frequency carrier pairs, when necessary, makes it possible to significantly increase the spectrum utilization (capacity) in a cellular system using asymmetric up-link and down-link for example in WCDMA systems.
