    Abstract: Embodiments may be directed to techniques to determine physical downlink control channel (PDCCH) candidates to assign to a user equipment (UE) based on one or more aggregation levels, each PDCCH candidate in a highest aggregation level of the one or more aggregation levels assigned by a random distribution over a whole control channel element (CCE) domain, and each PDCCH candidate in one or more non-highest aggregation levels of the one or more aggregation levels assigned a random distribution over one or more CCEs utilized by PDCCH candidates of the highest aggregation level. Embodiments also include selecting at least one of the PDCCH candidates to utilize to send downlink control information (DCI) to the UE, and causing transmission of the DCI to the UE via the PDCCH candidates selected.

    Abstract: Techniques for transmitting hybrid automatic repeat request (HARQ) feedback by narrowband Internet-of-Things (NB-IoT) devices are provided. NB-IoT user equipment (UE) can transmit HARQ feedback in response to a narrowband physical downlink shared channel (NPDSCH) received over a downlink (DL). NB-IoT UEs can transmit the responsive HARQ feedback over a narrowband physical uplink shared channel (NPUSCH) or a narrowband physical uplink control channel (NPUCCH). Options for defining the physical structures of the NPUCCH and NPUSCH and user multiplexing on the uplink (UL) are provided. Determination of an UL resource allocation by determining resources in time, frequency, and the code domain for the HARQ feedback transmissions are also provided. Higher level signaling and/or indications provided in downlink control information (DCI) can be used to determine the time, frequency, or code domain resources.

    Abstract: A synchronization signal design is described for narrowband Internet of Things Communications. The synchronization signals facilitate time and frequency synchronization between an eNB and UEs. In one example, operations include generating an NB-Iot Secondary Synchronization Signal (N-SSS) using a Zadoff-Chu (ZC) sequence, scrambling the ZC sequence using a scrambling sequence, and transmitting the resulting scrambled NB-Iot Secondary Synchronization Signal (N-SSS) by the eNB in a periodic manner, wherein, the eNB has a cell identifier and the cell is identified by a combination of the root of the ZC sequence and the scrambling sequence.

    Abstract: Resource allocation techniques for device-to-device (D2D) discovery are described. In one embodiment, for example, user equipment (UE) may comprise at least one radio frequency (RF) transceiver to receive device-to-device (D2D) configuration information comprising a D2D discovery period index value for a first D2D discovery period and logic, at least a portion of which is in hardware, the logic to determine a D2D discovery period index value for a second D2D discovery period based on the D2D discovery period index value for the first D2D discovery period and determine a set of D2D discovery resource allocation parameters for the second D2D discovery period based on a set of D2D discovery resource allocation parameters for the first D2D discovery period and the D2D discovery period index value for the second D2D discovery period. Other embodiments are described and claimed.
