Abstract
A method and system in which the control channels of an associated base station directly correspond to certain time slots of a radio channel frame, which also includes time slots being utilized for traffic channels. The time slots being utilized as control channels are marked with uniquely defined control channel indicators which include unique Sync Words and unique control channel identification words. The mobile station recognizes the uniquely defined control channel indicators and identifies those particular time slots as control channels so as to distinguish from the time slots which are not being used as control channels.
