Abstract: A technique to receive a Multimedia Broadcast Multicast Service (MBMS) broadcast, in which a plurality of source symbols and repair symbols of a broadcast from a broadcast source are received at a UE. The source symbols and repair symbols are based on fountain codes, so that not all of the repair symbols are used to recover the originally sourced data. An application layer of the UE recovers the sourced data and places the receiver in a power-save mode following the last repair symbol used to recover the sourced data, so that remaining repair symbols are not received by the receiver and subsequently processed.
