Abstract: Technology for an eNodeB operable to perform downlink (DL) transmissions using a Long Term Evolution (LTE) control region of a subframe for enhanced machine type communication (eMTC) is disclosed. The eNodeB can encode a system information block type 1 bandwidth reduced (SIB1-BR) for transmission 5 to a bandwidth reduced low complexity or coverage enhancement (BL/CE) user equipment (UE). The SIB1-BR can include an indication that the LTE control region in the subframe includes information for at least one of a machine type communication (MTC) physical downlink control channel (MPDCCH) transmission or a physical downlink shared channel (PDSCH) transmission. 10 The eNodeB can encode at least one of the MPDCCH transmission or the PDSCH transmission for delivery in a downlink over the LTE control region in the subframe to the BL/CE UE.

Abstract: A service device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component or network management component) can process or generate a Downlink Control Information (DCI) that schedules a Physical Uplink Shared Channel (PUSCH) transmission in a PUSCH. The PUSCH transmission can be generated based on a Demodulation Reference Signal (DMRS) according to a Discrete Fourier Transform (DFT) spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveform in uplink. A sequence of the DMRS can be generated based on a Gold sequence and a Pi/2 Binary Phase-Shift Keying (BPSK) modulation.

Abstract: Technology for a user equipment (UE) operable to assist a Next Generation NodeB (gNB) for beamforming is disclosed. The UE can determine a covariance matrix for a channel between the UE and the gNB. The UE can quantize the covariance matrix to obtain a quantized covariance matrix. The quantized covariance matrix can include M best diagonal entries that are selected from the covariance matrix, wherein M is an integer. The UE can encode the quantized covariance matrix as feedback for transmission to the gNB.
