Abstract: A user equipment (UE) can include processing circuitry coupled to memory. To configure the UE for New Radio (NR) communications above a 52.6 GHz carrier frequency, the processing circuitry is to decode radio resource control (RRC) signaling to obtain a cyclic shift value in time domain. The cyclic shift value is associated with a demodulation reference signal (DM-RS) antenna port (AP) of a plurality of available DM-RS APs. A single carrier based waveform DM-RS sequence corresponding to the DM-RS AP is generated using a base sequence and the cyclic shift value. The single carrier based waveform DM-RS sequence is encoded with uplink data for transmission to a base station using a physical uplink shared channel (PUSCH) using a carrier above the 52.6 GHz carrier frequency.

Abstract: Systems, methods, and circuitries are provided for determining fallback behavior in a user equipment (UE) wireless communication device. The method includes signaling an enhanced processing time capability and fallback type to the wireless network, wherein the processing time capability includes respective numbers of transport blocks per slot the UE can process mapped to different respective specified numbers of serving cells. A number of configured serving cells that support the enhanced processing time capability is determined. The method includes determining, based on the number of configured serving cells, a maximum number of transport blocks per slot that will be communicated between the UE and the configured serving cells. A fallback behavior based on the determined maximum number of transport blocks per slot and the fallback type is determined.

Abstract: In one embodiment, an apparatus includes memory storing instructions and processing circuitry coupled to the memory. The processing circuitry is to implement the instructions to select a resource block group (RBG) size configuration from a set of RBG size configurations based on a bandwidth part (BWP) size. Each RBG size configuration is to indicate RBG sizes associated with respective ranges of BWP sizes, and the RBG sizes are to indicate a number of frequency-domain physical resource blocks (PRBs) for physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) transmissions. The processing circuitry is further to implement the instructions to allocate PRBs for communication between the gNB device and a user equipment (UE) device via the PDSCH or PUSCH transmissions based on the selected RBG size, and to encode downlink control information (DCI) that indicates the allocated PRBs for transmission to the UE device.

Abstract: Disclosed herein are timing determination techniques for 5G radio access network (RAN) cells. According to various such techniques, a user equipment (UE) may receive a downlink (DL) scheduling command to schedule a DL data transmission from a base station. The UE may identify a scheduled slot for transmission of hybrid automatic repeat request (HARQ) feedback corresponding to the DL data transmission based on a received slot of the DL data transmission and an applicable slot offset value. The applicable slot offset value may indicate a number of slots by which the received slot precedes the scheduled slot. The applicable slot offset value may be identified from a value set based on an indicator comprised in the DL scheduling command, or may be identified using the various other techniques described herein.

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.
