    Abstract: Handling uplink transmissions by UEs in unlicensed carrier components, in the context of 3GPP eLAA, enhanced license assisted access, and in particular, the configuration by the eNodeB of multi-carrier LBT, Listen Before Transmit, is discussed. The eNodeB signals together with the Uplink grant the LBT procedure to be used before transmitting in uplink, either a short, Category 2 LBT procedure, or else a longer, category 4 LBT procedure. The eNodeB signals, for a particular carrier component, the same LBT procedure it has used itself to sense and then securing the carrier. Also, when pauses occur during the uplink transmission on contention-based shared channels involved in eLAA communications, various procedures may be used to restart transmissions on the contention-based shared channels on the uplink when the original channel occupancy was reserved by a serving base station.

    Abstract: The extension of NB-IoT and eMTC communications into the unlicensed spectrum introduces a number of problems associated with channel quality measurement and reporting. A method, apparatus, and computer readable medium are presented that provide a technique for channel quality measurement and reporting that addressed such problems. A UE apparatus measures a CQI measurement for each of a plurality of groups of hopping frequencies, wherein a set of hopping frequencies is grouped into the plurality of groups and reports a CQI for each of the plurality of groups. A base station may configure the UE for CQI reporting and may receive a CQI for each of a plurality of groups of hopping frequencies, wherein a set of hopping frequencies is grouped into the plurality of groups. The set of hopping frequencies comprise frequencies in an unlicensed spectrum.

    Abstract: In enhanced licensed assisted access (eLAA), providing several approaches to report the CSI measurement may be desirable to provide flexibility in CSI reporting, especially in aperiodic CSI reporting. Further, a difference in using a licensed carrier and an unlicensed carrier may be considered during communication. In addition, assigning different transmit power usage based on different transmission types may be desired. The apparatus may be a user equipment (UE). The apparatus may be a UE. The UE receives a grant for uplink communication. The UE determines a reporting subframe based on the grant. The UE determines whether to select, as a reference subframe, a triggering subframe in which the grant is received or a subframe before the reporting subframe. The UE transmits, in the reporting subframe, channel state information (CSI) measured in the reference subframe.

    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for wireless communication, and more particularly, to design principles for extending Internet of Things (IoT) (e.g., narrowband IoT (NB-IoT), machine type communication(s) (MTC), etc.) into an unlicensed radio frequency (RF) band spectrum. In certain aspects, the method generally includes determining an interlace structure of tones, within an unlicensed radio frequency (RF) spectrum, available to a wireless node for communication, and communicating based on the interlace structure. In some aspects, the communicating involves hopping between tones within the interlace structure during different communication intervals.
