mobile communication system and network apparatus for communicating data to and / or mobile units, and method for communicating data in a mobile communication system

摘要

A method for communicating data in a mobile communications system, the system comprising: one or more base stations arranged to communicate data to or from the mobile units via a wireless access interface within one or more frequency bands, and one or more of the base stations being arranged to provide a plurality of logically separate carriers for transmitting data to mobile units, wherein each of the logically separate carriers comprises physical communications resources within the one or more frequency bands of the wireless access interface, a first group of one or more mobile units arranged to communicate with the one or more base stations via at least a first carrier of the plurality of carriers; and a second group of one or more mobile units arranged to communicate with the one or more base stations via at least a second carrier of the plurality of carriers. The method comprises providing common information on the first carrier, the common information being for at least one mobile unit in the first group and for at least one mobile unit in the second group; providing allocation information in the first carrier, the allocation information comprising an indication of the location of the common information within the first carrier; providing allocation information in the second carrier, the allocation information comprising an indication of the location of the common information within the first carrier; and at least one mobile unit accessing the common information provided in the first carrier upon reception of the allocation information in the second carrier.
