Abstract

A method for transmitting data in a single-frequency network in a Long Term Evolution (LTE) network includes receiving media for broadcast in a broadcast area of a plurality of broadcast areas associated with a single-frequency network, wherein the broadcast area comprises a plurality of cells; identifying a subset of defined broadcast resources for broadcasting the media to the broadcast area; broadcasting the media to the broadcast area using the subset of defined broadcast resources; and broadcasting a null pattern on the subset of defined broadcast resources in adjacent broadcast areas to the broadcast area. An associated LTE network and broadcast controller are also described.
