    Abstract: Technology for performing device-to-device (D2D) communications is disclosed. A user equipment (UE) can identify D2D data to be transmitted from the UE. The D2D data can be identified when the UE is in a radio resource control (RRC) idle. The UE can be limited to using a defined resource allocation mode to transmit the D2D data from the UE. A service request procedure can be initiated at the UE. The service request procedure can trigger the UE to perform an RRC connection establishment procedure with an evolved node B (eNB) to switch the UE from the RRC idle mode to an RRC connected mode. The UE can receive an uplink (UL) grant from the eNB for communicating the D2D data from the UE. The UE can send the D2D data using the UL grant provided by the eNB.

    Abstract: Timing determination techniques for 5G radio access network cells are described. According to various such techniques, during a random access procedure in a 5G cell, user equipment (UE) may determine slot offset values applicable to various transmissions associated with the random access procedure using procedures that do not rely on UE-specific radio resource control (RRC) signaling. According to some such techniques, during system information acquisition in a 5G cell, a UE may determine applicable slot offset values for one or more system information block (SIB) transmissions using procedures that do not rely on UE-specific radio resource control (RRC) signaling. Other embodiments are described and claimed.

    Abstract: Methods and apparatuses for communicating in a cellular communications network, including provision of a user equipment comprising processing circuitry to: receive from a first cell a control signal comprising a physical Time Division Duplex Uplink-Downlink configuration indicator channel (PTCICH); decode from the PTCICH a Time Division Duplex Uplink-Downlink (TDD UL-DL) configuration; and communicate with the first cell having applied the TDD UL-DL configuration in respect of subframes associated with the first cell, wherein: the PTCICH spans less than or equal to 32 Resource Elements. Also user equipment comprising processing circuitry to: receive a control signal from a first cell; decode the control signal received from the first cell thereby to determine a second cell TDD UL-DL configuration; and communicate with the second cell having applied the second cell TDD UL-DL configuration in respect of subframes associated with the second cell.
