Resource change notification in carrier aggregated broadcast communication

摘要

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 is described. The method comprises, at a base station 110: receiving a first message comprising 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 comprising 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. Generation of the second message may comprise populating a dedicated channel indication (DCI) format 1C message with an indication of a multicast broadcast multimedia service (MBMS) control channel (MCCH) that has been modified.
