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: Embodiments described herein include devices, methods, and instructions for managing beam interpolation in massive multiple-input multiple-output (MIMO) communications. In one example embodiment, an evolved node B is configured to transmit to a UE using massive MIMO by transmitting multiple beamformed reference signals on multiple transmission beams each associated with a different plurality of antennas. The eNB receives beam interpolation information back from the UE, and then generates a data transmission that is sent to the UE using an interpolated transmission beam from a first and second transmission beam.

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) configured to perform beam failure recovery. The UE can encode a beam failure recovery (BFR) request for transmission on a physical random-access channel (PRACH) or a physical uplink control channel (PUCCH) to a next generation node B (gNB). The UE can monitor a dedicated physical downlink control channel (PDCCH) control resource set (CORESET) for a response from the gNB to the beam failure recovery request. The UE can select a default physical downlink shared channel (PDSCH) beam, wherein it is assumed, at the UE that a same quasi co-location (QCL) assumption for a PDSCH as a QCL assumption for the dedicated PDCCH CORESET; or a PDSCH demodulation reference signal (DMRS) is QCLed with a downlink (DL) reference signal (RS) of an identified candidate beam by the UE. The UE can decode a beam failure recovery request response from the gNB.

Abstract: Apparatus that sends uplink control information (UCI) from user equipment (UE) to a network node, generates elements of the UCI including at least one of hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback for one or more uplink (UL) resources, a scheduling request (SR), a channel state information (CSI) report and a beam related information report in response to a trigger set by the network node. The apparatus encodes the UCI elements for transmission via a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) of the one or more UL resources. The one or more UL resources may be UL slots or UL portions of downlink-uplink (DL-UL) slots received from a network node.

Abstract: Technology for a user equipment (UE) configured for communication of sounding reference signal (SRS) resources is disclosed. The UE can decode a radio resource control (RRC) signal indicating an SRS to transmit with a physical uplink control channel (PUCCH), wherein the PUCCH and the SRS are quasi co located (QCLed) based on a spatial received parameter. The UE can encode an SRS for transmission using the spatial received parameter. The UE can encode uplink control information (UCI) for transmission in the PUCCH using the spatial received parameter. The UE can have a memory interface configured to send to a memory the spatial received parameter.

Abstract: An apparatus of a wireless communication device operable to communicate channel state information in a wireless network can include memory and processing circuitry coupled to the memory. The processing circuitry is arranged to derive one or more principal eigen beams from received Orthogonal Frequency Division Multiple Access (OFDMA) signals, the one or more principal eigen beams having a rank greater than or equal to one. Quantized eigen beams may be derived from the one or more principal eigen beams. A bit pattern of the quantized eigen beams and at least one of a wideband channel quality indicator (CQI) or a subband CQI may be conditioned on the quantized eigen beams. Channel State Information Reference Signal (CSI-RS) may be encoded with the conditioned bit pattern for transmission to an Evolved Node-B (eNB) in the wireless network.

Abstract: Devices and methods of beamforming are generally described. A UE transmits to an eNB a BRSRP report having selected BRSRP values and associated BRS IDs. An active link list, a CSI resource indication, and a first active link are used to measure the CSI resource and CSI feedback is sent. A serving link ID is provided to indicate a second active link to use for control and data reception. Rx beams are trained based on multiple instances of each BRS and the eNB supplies selection criteria for the BRSRP report. The Rx beams are refined based on BRRS and the second active link is dependent on BRRSRP or CSI feedback. When configured for dual beam operation, the BRSRP feedback corresponds to BRSRP value pairs and dual Rx beams associated with a pair of serving link IDs are used.
