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: Air interface resource utilization techniques for wireless communication networks are described. According to various such techniques, one or more narrow band resource regions (NBRRs) may be defined for use in conjunction with narrow band (NB) transmissions in an NB cell. In some embodiments, one or more such NBRRs may be designated as broadcast NBRRs, and may be used to carry a majority, most, or all of the broadcasted information within the NB cell. In various embodiments, another NBRR may be designated as a primary NBRR, and may be used to carry synchronization signals for the NB cell. In some such embodiments, the primary NBRR may also be used to carry NB physical broadcast channel (NB-PBCH) transmissions and NB master information blocks (NB-MIBs). Other embodiments are described and claimed.

Abstract: This disclosure describes systems, methods, and devices related to multiplexing uplink transmissions. A user equipment (UE) device may detect a first set of beta offset indices associated with multiplexing high priority uplink control information (UCI) into a physical uplink shared control channel (PUSCH); detect a second set of beta offset indices associated multiplexing low priority UCI into the PUSCH; detect downlink control information (DCI) using a physical downlink control channel (PDCCH) which schedules the PUSCH; determine, based on the first set of beta offset indices and the second set of beta offset indices, that UE device is to multiplex the high priority UCI with the low priority UCI into the PUSCH; and encode, based on the second set of beta offset indices, a multiplexed uplink transmission for transmission to the 5G network device using the PUSCH, the multiplexed uplink transmission comprising the high priority UCI and the low priority UCI.
