Abstract

A method and an apparatus for preserving compatibility between legacy mode of operation and new mode of operation in a communication system, wherein allocation of resources is different in the legacy mode of operation and the new mode of operation is disclosed. Accordingly, an entity of a wireless access network, e.g., a base station, transmits signals comprising information about reallocation of resources from a legacy mode of operation to a new mode of operation. These signals are received at another entity of a wireless access network, e.g., a subscriber station, which then controls use by the subscriber station of resources allocated to the subscriber station in accordance with the information.
