Abstract

A method and apparatus for providing new configurations for transmitting control information between a mobile terminal and a network using a common control channel (CCCH) logical channel/transport channel. The new configurations enable messages to be sent that are larger than currently allowed and the availability of the new configurations is indicated such that mobile terminals that do not support the new configurations are not impacted.
