  • Patent number: 10334562
    Abstract: A base station transmits and a UE detects broadcast information when the UE operates in a Coverage Enhancement (CE) mode. The base station transmits repetitions of signaling conveying broadcast information in one or more subframes of each frame in a quadruple of frames. The transmission is intermittent in time. To detect the broadcast information, the UE blindly combines and decodes the repetitions of signaling assuming their existence. The base station informs the pattern for the intermittent transmissions of the signaling to UEs connected to the base station or to other base stations.
