Communication units and methods for resource change notification in broadcast communication

摘要

[enhanced] Mobile/Multimedia Broadcast Multicast Service (eMBMS) allows transmission of data to multiple user equipments simultaneously. Carrier aggregation (CA) allows user equipments to communicate simultaneously on multiple component carriers (CC) 415/460, with one or more CCs being applied to each of one or more services. Existing MBMS signalling formats only allow MCCH change information about the same component carrier. The invention proposes a system wherein cross carrier scheduling can provide information about MCCH changes on other/multiple carriers. The cross carrier information may be a dedicated channel information (DCI) message in the 1C format 410, it may be transmitted on a PDCCH.
