Abstract: Narrowband Internet of Things synchronization signals are described that carry offset information. In one example an evolved NodeB (eNB) to performs operations to transmit synchronization signals for time and frequency synchronization between the eNB and user equipments (UEs) for narrowband Internet of things (NB-Iot). The operations include concatenating a plurality of short ZadoffChu (ZC) sequences each having a different root index, the ZC sequences being ordered to indicate an offset for use by a UE, generating an NB-Iot Primary Synchronization Signal (NB-PSS) using the concatenation of short ZadoffChu (ZC) sequences, and transmitting the resulting NB-PSS by the eNB in a periodic manner to the UE, wherein, the offset is identified by the order of the ZC sequences.

Abstract: Radio frame configuration circuitry for use in a device of a wireless communication system is provided. The radio frame configuration circuitry uses control circuitry to select between a plurality of different time-division duplex, TDD, configurations for a radio frame having slots with a configured duration. Transceiver circuitry performs TDD communications based on selections made by the control circuitry such that an average periodicity of switching between transmission of information and reception of information during the TDD communication is the same despite switching between different ones of the plurality of different TDD configurations. The radio frame configuration circuitry can be incorporated in a UE or an eNodeB or a Peer Radio Head. A corresponding method is provided.

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 efficient distributed scheduling is provided using tentative grants. A UE can receive a transmission request from a Tx UE, and from additional Tx UEs. Each Tx request can include a priority level of the transmitter UE sending the transmission request, to form a priority list. An incompatible list can be formed based on a signal to interference ratio of each transmitter with the UE. A grant message and the incompatible list can be transmitted for n−1 iterations from selected UEs based on the priority list and incompatible list. A tentative bandwidth grant can then be transmitted at an nth iteration to tentatively allow the transmitter UE to send a D2D communication to the UE in the bandwidth grant.
