Abstract: An eNodeB operated by a first operator is able to align an ON-OFF cycle operation for interference avoidance. The eNodeB receives, from another eNodeB operated by a second operator a physical broadcast channel (PBCH) and a physical downlink shared channel (PDSCH). A transmission coverage of the eNodeB partially overlaps with a transmission coverage of the other eNodeB. The PBCH carries a master information block (MIB), and the PDSCH carries a single system information block (SIB) identifying available unlicensed channel and including public land mobile network (PLMN) identities for networks operating using the unlicensed channel. The eNodeB uses the MIB and SIB1 to identify that the second eNodeB is operated by the second operator.

Abstract: Methods and apparatus are provided for a base station to transmit and for a UE to detect 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.
