EXTENDING THE CONTROL CHANNEL REGION OF A COMMUNICATIONS SYSTEM IN BACKWARDS COMPATIBLE MANNER

摘要

In a method of adapting a control channel in a network node in a communication system, providing (S20) a control format indicator for the control channel, and dynamically determining and providing (S10) control channel redefinition information, which control channel redefinition information together with said control format indicator provides a redefined control channel. Subsequently the control channel is adapted (S30) based on said control format indicator and said control channel redefinition information to provide a redefined control channel for signaling to said at least one user equipment, Finally, scheduling (S40) user equipment in a sub frame based on the redefined control channel.
