Abstract: Technology for performing downlink scheduling is disclosed. One or more subframes can be identified within a defined frame of a primary cell to perform cross-subframe scheduling for a secondary cell. The primary cell can be configured to communicate with a user equipment (UE) using a licensed band and the secondary cell can be configured to communicate with the UE using an unlicensed band. The cross-subframe scheduling can be performed for one or more downlink subframes of the secondary cell using the one or more subframes of the primary cell.

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: Embodiments of the present disclosure may include monitoring, at a physical layer, for a physical uplink shared channel (PUSCH) trigger for a PUSCH transmission, determining, at the physical layer, the PUSCH trigger is not received, wherein a wireless communication device is not to perform the PUSCH transmission based on the determination that the PUSCH trigger is not received, and considering, at a medium access control (MAC) entity, the PUSCH transmission to have been performed. Other embodiments may be described and/or claimed.

Abstract: Embodiments of latency reduction for wireless data transmission are generally described herein. A user equipment (UE) identifies a shortened transmission time interval (xTTI) length configuration for a time division duplexing (TDD) component carrier (CC), the xTTI length configuration comprising a length in time or a length in orthogonal frequency division multiplexing (OFDM) symbols. The UE identifies scheduling timing and hybrid automatic repeat request (HARQ) timing of physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH) on the TDD CC based on the identified xTTI length configuration. The UE signals for transmission of a HARQ acknowledgement (HARQ-ACK) based on the identified xTTI length configuration.

Abstract: Devices and methods of reducing overall Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) of user equipment (UE) using a large amount of carrier aggregation are generally described. The UE may receive a subframe from an enhanced NodeB (eNB). The subframe may contain a physical downlink control channel (PDCCH) formed in accordance with a Downlink Control information (DCI) format. The DCI format may comprise a Downlink Assignment Index (DAI) for Time Division Duplexed (TDD) and Frequency Division Duplexed (FDD) operation. The UE may determine, dependent on the DAI, a number and ordering of Hybrid Automatic Repeat Request-Acknowledgment (HARQ-ACK) bits to be transmitted on a Physical Uplink Shared Channel (PUSCH) and subsequently transmit the HARQ-ACK bits.

Abstract: User equipment (UE), an enhanced NodeB (eNB) and method of improving positioning accuracy and enabling vertical domain positioning of the UE are generally described. The UE may receive a prsInfo control signal having at least one PRS configuration and subsequently a plurality of Reference Signals (RSs). The RSs may have a first Positioning Reference Signal (PRS) pattern in a first set of PRS subframes and a second PRS pattern in a second set of PRS subframes received prior to a subsequent first set of PRS subframes. The RSs may have a vertical positioning RS and a lateral positioning RS. The UE may measure PRS resource elements (REs), each having a PRS, in the first and second PRS pattern. The UE may transmit a measurement of the PRS in the first and second PRS pattern. The patterns may enable horizontal and vertical positioning to be determined.

Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K x a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

Abstract: Embodiments of an eNB to operate in accordance with a coverage enhancement mode are disclosed herein. The eNB may comprise hardware processing circuitry to, during a legacy sub-frame, transmit a system information block (SIB) in legacy SIB frequency resources according to a legacy SIB transmission format and refrain from transmission of channel state information reference signals (CSI-RS). The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first portion of the SIB in first SIB frequency resources included in the legacy SIB frequency resources. The hardware processing circuitry may be further to, during a first coverage enhancement sub-frame, transmit a first set of CSI-RS in first CSI-RS frequency resources that include at least a portion of the legacy SIB frequency resources.

Abstract: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB), and methods for communication of uplink messages are generally described herein. The UE may receive, from an eNB, one or more downlink control messages that may indicate an allocation of PUCCH channel resources. The UE may transmit an uplink control message in at least a portion of the allocated PUCCH channel resources. When the PUCCH channel resources are allocated according to an edge configuration, the PUCCH channel resources may be restricted to a lower edge portion and an upper edge portion of the network channel resources. When the PUCCH channel resources are allocated according to a distributed configuration, the PUCCH channel resources may include one or more middle portions of the network channel resources. The middle portions may be exclusive to the lower edge and upper edge portions.
