Abstract

An apparatus operable in a communication system is described. The apparatus includes means for sending a connection reconfiguration message using a first configuration. The apparatus also includes means for receiving an acknowledgement message using the first configuration. The apparatus also includes means for applying a second configuration as indicated in the acknowledgement message. The apparatus also includes means for sending a connection reconfiguration complete message uplink grant in a common search space. The apparatus also includes means for receiving a connection reconfiguration complete message using the second configuration.
