Abstract: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB), and methods for communication of uplink messages are generally described herein. The UE may receive, from an eNB, one or more downlink control messages that may indicate an allocation of PUCCH channel resources. The UE may transmit an uplink control message in at least a portion of the allocated PUCCH channel resources. When the PUCCH channel resources are allocated according to an edge configuration, the PUCCH channel resources may be restricted to a lower edge portion and an upper edge portion of the network channel resources. When the PUCCH channel resources are allocated according to a distributed configuration, the PUCCH channel resources may include one or more middle portions of the network channel resources. The middle portions may be exclusive to the lower edge and upper edge portions.

Abstract: Technology for a user equipment (UE) operable to decode a resource mapping pattern of a phase tracking reference signal (PT-RS) received from a base station in a wireless network is disclosed. The UE can decode control signaling received in a downlink from the base station. The control signaling can indicate a resource mapping pattern for a PT-RS. The UE can identify the resource mapping pattern for the PT-RS based on the control signaling received from the base station. The UE can encode one or more PT-RS for transmission to the base station in an uplink in accordance with the resource mapping pattern for the PT-RS.

Abstract: Technology for a user equipment (UE) using a self-contained scheduling resource to communicate with an eNodeB within a wireless communication network is disclosed. The UE can select, at the UE, a selected eNodeB transmission (Tx) beam and a selected UE reception (Rx) beam based on a highest power beamforming reference signal (BRS) received power (BRS-RP). The UE can signal a transceiver of the UE to transmit to the eNodeB a scheduling request (SR), using the selected Rx beam, on a scheduling request (SR) resource in a self-contained subframe according to a time and frequency location of the selected eNodeB Tx beam. The UE can process an advanced physical downlink control channel (xPDCCH), received from the eNodeB, for an uplink (UL) grant using the selected UE RX beam.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH), wherein a cyclic redundancy check (CRC) of the PDCCH is scrambled by a radio network temporary identifier (RNTI). In some cases, if the RNTI that scrambles the PDCCH is a modulation coding scheme (MCS) cell RNTI (MCS-C-RNTI), cell RNTI (C-RNTI), or a configured scheduling RNTI (CS-RNTI), the UE may determine that: one or more PT-RSs are present in the PDSCH, a time density parameter of the PT-RSs is equal to one, and a frequency density of the PT-RSs is equal to two.

Abstract: An apparatus of a user equipment (UE) comprises one or more baseband processors to process payload size comprising a number of feedback bits for a hybrid automatic repeat request-acknowledgement (HARQ-ACK) configuration received from a New Radio (NR) NodeB (gNB) for physical uplink shared channel (PUSCH) transmission without grant, and to determine a size of reserved resource elements (REs) and mapping pattern in accordance with the configured HARQ-ACK payload size, and to transmit uplink shared channel on PUSCH without grant which is rate-matched around the reserved REs. The UE alternatively comprises one or more baseband processors to process a downlink control information (DCI) grant received from a to schedule a PUSCH transmission, wherein the one or more baseband processors are configured for dynamic DCI grant overwriting to process a dynamic indication to interrupt the scheduled PUSCH transmission.
