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.

Abstract: A component carrier (CC) selection based aperiodic CSI report trigger configuration may be used to trigger one or more of channel state information (CSI) processes, CCs in cell groups, and/or CSI subframe sets to perform an aperiodic CSI report based on a value of a CSI request field in an uplink DCI format and serving cell information to indicate a serving cell where aperiodic CSI reporting is transmitted according to the detected uplink DCI format or a serving cell where PDCCH conveying the detected uplink DCI format is transmitted.

Abstract: Technology for contention free physical uplink shared control channel (PUSCH) transmission using listen before talk procedure is disclosed. In an example, an apparatus of a user equipment (UE) having circuitry configured to achieves low latency synchronization with an anchor enhanced Node (eNB) by sensing for a predetermined time period if any physical uplink shared channels (PUSCH) are idle with the anchor eNB for uplink (UL) synchronization; providing a unique UE identification in a PUSCH transmission; and communicating the PUSCH transmission in one of the idle PUSCH channels for contention free communication with the anchor eNB for uplink synchronization.
