Abstract
The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for using (or reusing) unused frequency resources/channels in a legacy radio access technology system (a first radio access technology system) such as GSM as additional/reused resources for a future/advanced radio access technology systems (a second radio access technology system) such as LTE wireless system. In one embodiment, the extension carrier may be used to simultaneously deploy/assign, e.g., LTE transmission in the same frequency band as the legacy radio access technology system such as GSM with LTE transmission occupying empty GSM time plus frequency slots. In a further embodiment, LTE system over-provisioning may be used so that individual GSM channel(s) can be deactivated and used by the LTE system.
