    Abstract: Control signaling mechanisms are provided to support data transmissions to or from a user equipment (UE) in an inactive state. In some embodiments, a UE in an inactive state receives DCI including: a cyclic redundancy check (CRC) scrambled by a radio network temporary identifier (RNTI) that is specific to a group of UEs, the group of UEs including the UE; and a resource assignment for a data transmission to the UE. The data transmission is then received on a physical shared channel. In further embodiments, a UE in an inactive state receives DCI including: a CRC scrambled by a paging RNTI; and a resource assignment for a paging message to the UE. A data transmission is received by the UE in the paging message or in a further transmission that is scheduled by the paging message.

    Abstract: Some embodiments of the present disclosure provide control signaling mechanisms to support data transmission by a user equipment (UE) that is in the RRC_INACTIVE state and, more generally, in any inactive state. Beyond simply supporting data transmission by a user equipment that is in the RRC_INACTIVE state, aspects of the present application provide mechanisms for configuring the UE for preamble transmission or sounding reference signal (SRS) transmission and for toggling between such transmissions. Aspects of the present application relate to mechanisms for enabling Timing Advance estimation, which mechanisms are not burdened with high overhead and which allow the UE to remain in the RRC_INACTIVE state.

    Abstract: Aspects of the present application use a linear transformation of a sparse mapped single carrier transmission at a transmitter, for which a comparable inverse transform of the linear transform applied at the transmitter can be applied at the receiver. The linear transform reduces the sparsity of sparse mapped symbols. The use of the linear transform to reduce the sparsity enables peak-to-average power ratio (PAPR) and/or cubic metric to be reduced as compared to if the linear transform is not used. The linear transforms may be implemented in a block-wise manner, element-wise manner or combination thereof.

    Abstract: Methods and devices are disclosed for encoding and transmitting data sequences for low data rate applications. An encoded data sequence is transformed and used to shape a multi-carrier pulse to create a narrow-band signal for transmission. Time domain tails of the narrow-band signal may be removed to decrease overhead. The data may be first encoded to create a sparse modulated data sequence. Multi-carrier pulse shaping may be carried out using frequency division multiplexing (FDM) or filter bank multi-carrier (FBMC) techniques. Alternatively, single carrier pulse shaping may be used to create the narrow-band signal.

    Abstract: Methods, devices and systems for encoding and transmitting data in a wireless communications system and, in particular, for unscheduled data transmissions including low data rate transmissions. The method for transmitting data in a wireless network includes mapping data according to a predefined sequence pattern from a group of sequence patterns to provide a spreading sequence that includes multiple non-zero elements and that is enabled to partially collide in the wireless network with other spreading sequences that have been mapped according to other sequence patterns from the group; and transmitting the spreading sequence. Multiple sequences may be received by a network node and decoded using successive interference cancellation (SIC) techniques.
