Abstract: A method supporting control channel change notification for at least one wireless communication unit capable of operating on a first serving communication cell and configured with access to at least one second serving communication cell in a wireless broadcast communication system. The method includes, at a broadcast server: supporting communication with at least one wireless communication unit via the at least one second serving communication cell; generating a message including an indication that a control channel change notification will be sent in the at least one first serving communication cell; transmitting the message to the at least one wireless communication unit operational in the at least one second serving communication cell; and transmitting the control channel change notification in the first serving communication cell.

Abstract: A method for supporting cross carrier indication of a control channel change notification for at least one wireless communication unit that is operating on a first serving communication cell and has been configured with access to at least one second serving communication cell in a wireless broadcast communication system. The method includes, at the base station: generating a message including a broadcast service identifier, wherein the broadcast service identifier identifies a control channel change of the at least one second serving cell accessible by the at least one wireless communication unit; and transmitting the message to the at least one wireless communication unit.

Abstract: A method for supporting cross carrier indication of a control channel change notification in a wireless communication system that provides broadcast services on a plurality of carriers. The method includes, at a base station: receiving a first message including an indication of a control channel change requirement; mapping at least one single broadcast service to a plurality of component carriers; generating a second message including a control channel change notification for the broadcast service based on the mapping; and transmitting the second message on at least one component carrier to at least one wireless communication unit.

Abstract: A relay device for supporting communications between a terminal device and a base station in a wireless communications system is described. The relay device comprises a transceiver arranged to at least receive an access request message from the terminal device; and a control processor operably coupled to the transceiver and arranged to process the access request message, extract information and determine therefrom a power delta value that is not based on a determination of pathloss between the relay device and the terminal device, generate a control element comprising the power delta value; and for relaying at least the control element to the base station. The control processor is further arranged to receive subsequently at least one physical uplink channel message from the terminal device wherein a transmit power level of the at least one physical uplink channel message is based at least on the power delta value.
