    Abstract: Embodiments of efeMTC synchronization signals for enhanced cell search and enhanced system information acquisition are described. In some embodiments, an apparatus of a base station (BS) is configured to generate a length-x sequence for an efeMTC synchronization signal, the length-x sequence configured for repetition in frequency domain within 6 physical resource blocks (PRB). In some embodiments, to generate the length-x sequence, the BS may be configured to select any one index of the set of root indices {1, 2, . . . , 63}, excluding the root indices 25, 29 and 34, to correspond to a different physical-layer cell identity (PCID). In some embodiments, the BS may be configured to encode RRC signaling to include a System Information Block (SIB) comprising configuration information for transmission of the efeMTC synchronization signal, and transmit the length-x sequence as the efeMTC synchronization signal in frequency resources according to the SIB.

    Abstract: Timing determination techniques for 5G radio access network cells are described. According to various such techniques, during a random access procedure in a 5G cell, user equipment (UE) may determine slot offset values applicable to various transmissions associated with the random access procedure using procedures that do not rely on UE-specific radio resource control (RRC) signaling. According to some such techniques, during system information acquisition in a 5G cell, a UE may determine applicable slot offset values for one or more system information block (SIB) transmissions using procedures that do not rely on UE-specific radio resource control (RRC) signaling. Other embodiments are described and claimed.

    Abstract: This disclosure relates to implementations to support non-UE-specific (i.e. common) and UE-specific search spaces (SS) for M-PDCCH. One implementation relates to a UE comprising RF circuitry to receive, from an eNB, configuration information of one or a plurality of common Search Spaces (CSSs) for M-PDCCH; and baseband circuitry to monitor the one or more configured CSS for M-PDCCH transmissions; wherein the RF circuitry and/or baseband circuitry is adapted to support a reduced bandwidth (BW). Another implementation relates to an eNB comprising RF circuitry to transmit configuration information of a plurality of CSSs for M-PDCCH to one or more UEs supporting a reduced BW, wherein the plurality of CSSs for M-PDCCH are differentiated by “based on functionality”-differentiation that includes the type of use case and/or an EC level of the UE.

    Abstract: Narrowband Internet of Things synchronization signals are described that carry offset information. In one example an evolved NodeB (eNB) to performs operations to transmit synchronization signals for time and frequency synchronization between the eNB and user equipments (UEs) for narrowband Internet of things (NB-Iot). The operations include concatenating a plurality of short ZadoffChu (ZC) sequences each having a different root index, the ZC sequences being ordered to indicate an offset for use by a UE, generating an NB-Iot Primary Synchronization Signal (NB-PSS) using the concatenation of short ZadoffChu (ZC) sequences, and transmitting the resulting NB-PSS by the eNB in a periodic manner to the UE, wherein, the offset is identified by the order of the ZC sequences.
