Abstract: Technology for a user equipment (UE) operable to perform downlink (DL) channel quality measurement reporting is disclosed. The UE can decode a system information block type y bandwidth reduced (SIBy-BR) received from an eNodeB. The SIB1-BR can instruct the UE to include a DL channel quality measurement report in a message 3 (Msg3) transmitted during a random access procedure between the UE and the eNodeB, wherein y is a positive integer greater than or equal to 1. The UE can determine a DL channel quality measurement for a DL channel between the UE and the eNodeB. The UE can encode the Msg3 for delivery over an uplink channel to the eNodeB. The Msg3 can be delivered during the random access procedure and can include the DL channel quality measurement report with the DL channel quality measurement.

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.
