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.

Abstract: A Device to Device (D2D) user equipment (UE) is configured to support synchronization in a D2D network. The D2D UE includes an antenna configured to communicate via a D2D communication. The D2D UE also includes processing circuitry configured to enter a communication Mode 2 when certain conditions are met. The certain conditions include: when a first timer (T310) for detecting radio link failure is running, a second timer (T311) for initiating the connection reestablishment is running, or a third timer (T301) for requesting connection reestablishment is running. In communication Mode 2, the D2D UE, on its own, selects resources from resource pool(s) to transmit D2D data and D2D control information. The processing circuitry further configured to exit the communication Mode 2 and enter a communication Mode 1 when the certain condition is no longer met. In communication Mode 1, the D2D UE uses resources configured by another station.

Abstract: Methods and apparatus are provided for a base station to transmit and for a User Equipment (UE) to receive repetitions of an enhanced physical downlink control channel (EPDCCH). Time and frequency resources for EPDCCH repetitions are defined together with restrictions in time resources to provide UE power savings. Time and frequency resources are also defined for repetitions of a physical downlink shared channel (PDSCH) transmission and for repetitions of a physical uplink shared channel (PUSCH) transmission. Methods and apparatus are also provided for the UE to transmit and for the base station to receive acknowledgement information in repetitions of a physical uplink shared channel (PUCCH).

Abstract: A network node in a wireless network performs a method for enhancing reliability in wireless communication. The method includes determining, at a first network node, that a current link with a second network node is broken. The method also includes attempting, at the first network node, to recover the current link. The method further includes, upon a determination that the current link is not recoverable, establishing, at the first network node, a new link with the second network node according to one of a plurality of switching rules, the switching rules ordered according to a priority among the switching rules.

Abstract: Methods and apparatus are provided for a base station to transmit and for a User Equipment (UE) to receive repetitions of an enhanced physical downlink control channel (EPDCCH) transmission or of a physical downlink shared channel (PDSCH) transmission. The UE is configured by the base station a set of numbers of repetitions for an EPDCCH transmission or a PDSCH transmission, respectively. The base station transmits an EPDCCH or a PDSCH according to a first number of repetitions from the set of numbers of repetitions. The UE determines a number, from the set of numbers, of repetitions for an EPDCCH reception in order to determine a first subframe for a reception of a PDSCH or a first subframe for a transmission of a physical uplink shared channel (PUSCH).

Abstract: An apparatus includes a User Equipment (UE) having a receiver and a decoder. The receiver is configured to receive, from an eNodeB (eNB), a signal indicating a configuration of a period to receive one or more Physical Downlink Control CHannels (PDCCHs) in respective one or more Transmission Time Intervals (TTIs). Each of the one or more PDCCHs conveys a same Downlink Control Information (DCI) format. The DCI format includes at least one field indicating a first Time Division Duplexing (TDD) UpLink-DownLink (UL-DL) configuration in a first cell for DL data receptions or UL data transmissions. A TDD UL-DL configuration includes ten TTIs each having a respective serial index from 0 to 9. The receiver is also configured to receive, from the eNB, at least one PDCCH of the one or more PDCCHs. The decoder is configured to decode the DCI format conveyed by the at least one PDCCH in a second cell. The period is a multiple of ten TTIs, and the one or more TTIs are in a last ten TTIs of the period.
