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: Technology for a user equipment (UE) operable to perform mission critical communications with an eNodeB is disclosed. The UE can transmit a physical random access channel (PRACH) signal to the eNodeB that indicates a mission critical communication to be performed between the UE and the eNodeB. The PRACH signal can be transmitted in accordance with a first transmission time interval (TTI). The UE can receive a random access response (RAR) message from the eNodeB that includes a timing advance (TA) and a resource allocation for the mission critical communication. The RAR message can be transmitted from the eNodeB using a second TTI. The UE can perform the mission critical communication with the eNodeB in an uplink using the TA and the resource allocation indicated in the RAR message. The mission critical communication can be performed using a physical uplink shared channel (PUSCH) and in accordance with the second TTI.

Abstract: A method for low overhead system information acquisition (LOSIA) is disclosed. The LOSIA method includes several techniques for transmitting common channels in a next generation Radio Access Technology (xRAT). Instead of transmitting system information in a periodic, static, cell-specific, wideband manner, the transmission is triggered by user equipment in an “on demand” manner. The LOSIA method allows the network to control the overhead, bandwidth, and periodicity, as well as other characteristics. The LOSIA method employs several different techniques to trigger the information upon which the network can act, for example, by transmitting different payloads depending on the received trigger.

Abstract: Technology described herein addresses symmetric uplink (UL)/downlink (DL) designs that can be applied to both uplink and downlink transmissions. A symmetric UL/DL design can define a Transmission Time Interval (TTI) format with control channels and data channels multiplexed using Frequency Division Multiplexing (FDM) or Time Division Multiplexing (TDM) to partition the control channels and the data channels within a Transmission Time Interval (TTI). A unified waveform can be applied to both UL and DL transmissions. Several Demodulation Reference Signal (DM-RS) designs are also described. A hybrid mode for UL transmissions is also described.

Abstract: Apparatus, systems, and methods to implement inter-beam mobility control in MIMO communication systems are described. In one example, apparatus of an evolved Node B (eNB) comprises circuitry to configure a periodic transmit (TX) beamforming process for a user equipment (UE), wherein a plurality of different TX beams are used in a plurality of different beamforming reference signals (BRS), receive, from the UE, a selected TX beam index which identifies a selected TX beam, and schedule subsequent transmissions to the UE on the selected TX beam. Other examples are also disclosed and claimed.
