Abstract: A user equipment (UE) can include processing circuitry configuring the UE for Dual Connectivity (DC) with a Master Node-B (MN) and a Secondary Node-B (SN). The processing circuitry is to decode connection reconfiguration information received from the MN. The connection reconfiguration information includes signaling radio bearer type 3 (SRB3) configuration information. The SRB3 configuration information originating from the SN and configuring a SRB3, where the SRB3 is for direct communication between the UE and the SN. At least one of a radio resource control (RRC) reconfiguration completion message or a measurement report message is encoded for transmission to the SN.

Abstract: Embodiments of a next generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. A gNB may be configurable to operate as a master gNB (MgNB). The MgNB may transmit radio-resource control (RRC) signaling to provide information for dual connectivity to allow the UE to utilize radio resources of both a master cell group (MCG) associated with the MgNB and a secondary cell group (SCG) associated with a secondary gNB (SgNB). The MgNB may transmit, to the SgNB, an SgNB release request message that indicates a partial suspension of the dual connectivity, wherein: a first portion of a configuration for the SCG is to be maintained and a second portion of the configuration for the SCG is to be released.

Abstract: An apparatus of a network (NW) configured to: encode a new radio (NR) Discovery Reference Signal (DRS) transmission, the NR DRS transmission including a synchronization signal block (SSB) and channel state information (CSI) reference signal (RS) (CSI-RS). The apparatus is further configured to configure the NW to transmit the NR DRS transmission. The RS-CSI may be a fragmented RS-CSI including a first fragmented portion and a second fragmented portion, where the apparatus is configured to encode a symbol of the NR DRS transmission to comprise the first fragmented portion, a symbol of the SSB, and the second fragmented portion, where the symbol of the SSB is encoded on a physical broadcast channel (PBCH) portion of the NR DRS transmission.

Abstract: An apparatus of a user equipment (UE) includes processing circuitry configured to decode a master information block (MIB) using a set of physical broadcast channel (PBCH) symbols received within a downlink frame to obtain system frame number (SFN) information. The downlink frame includes multiple copies of the PBCH symbols within at least three subframes of the downlink frame. A system information block (SIB) may be decoded based on the SFN information, to obtain uplink channel configuration information. Random access channel (RACH) procedure may be performed with a base station (BS) based on the uplink channel configuration information, to obtain an uplink resource assignment. A connection setup completion message can be encoded for transmission to the BS using the uplink resource assignment. The set of PBCH symbols can include a set of four legacy PBCH symbols.

Abstract: Systems and methods of measuring reference signals in a multefire scenario are described. A UE receives control information anchor channel dependent on whether the UE is in an adaptive frequency hopping system (FHS) and whether the FHS is a LBT FHS. The reference signals are received on an unlicensed band via the anchor and/or a non-anchor channel and measured for RRM and/or in-sync or out-of-sync measurements. RRM measurements are transmitted to the eNB for mobility management and otherwise the validity of an in- or out-of-sync indication is determined and a counter started when valid. The control information has a subframe configuration and resource allocation, which is used for SRS transmission on the non-anchor channel. Uplink scheduling information is received on the anchor channel for data transmission on the non-anchor channel based on the SRS.
