Abstract: It is recognized herein that current LTE reference signals may be inadequate for future cellular (e.g., New Radio) systems. Configurable reference signals are described herein. The configurable reference signals can support mixed numerologies and different reference signal (RS) functions. Further, reference signals can be configured so as to support beam sweeping and beamforming training.

Abstract: System information can include a basic set of system information and additional system information. A UE can receive the basic set of system information and then later request or receive the additional system information. Messages can use tags which can be used to look up locally stored system information. If a tag does not correspond to any locally stored system information, the system information and an associated tag can then be requested. Messages can be indicative of a cluster identity associated with cells. When the UE goes into a new cell, the cluster identity can be checked to see if system information from a prior call can be reused.

Abstract: A first apparatus detecting, from a second apparatus, one or more swept downlink beams, wherein each swept downlink beam comprises a synchronization signal block; making a measurement of a signal contained within the synchronization signal block of each detected swept downlink beam; decoding a message contained within the synchronization signal block of each detected swept downlink beam; selecting, based on the measurements and decoded message, a synchronization signal block; determine, based on the selected synchronization signal block, a paging block; detecting, within the paging block, a paging indication; and receiving, based on the paging indication, a paging message.

Abstract: Flexibly configured containers consisting of resources within time-frequency blocks may be used to support multiple numerologies in new radio architectures. Uplink control may be defined in resources within a container, or in dedicated resources, by various nodes. Sounding reference signal resources may be dynamically configured for each numerology. The sequence length may be adapted, as well as the time domain location of symbols. Time, frequency, and orthogonal resources may be allocated via a downlink control channel or a radio resource control. Sounding reference signals may be pre-coded, and pre-coding weights may be based on a codebook or non-codebook approaches, e.g., via a radio resource control or a downlink RRC or DL control channel. Pre-coded sounding reference signals may be adapted to user equipment antenna configuration. Further, NR-SRS may be used as UL demodulation RS (DM-RS).

Abstract: A wireless transmit/receive unit (WTRU) is configured to receive at least three sets of parameters associated with power saving. A first set of the parameters is associated with an idle state. A second set of the parameters is associated with a connected state. A third set of the parameters is associated with not being in a connected state and remains registered with a network and maintains a packet data network (PDN) connection. The WTRU is configured to enter active times based on the third set of parameters on a condition that the WTRU is not in the connected state and remains registered with the network. During the active times, the WTRU is configured to monitor physical downlink control channels (PDCCHs) for paging messages.

Abstract: Multiple mobility sets are maintained for nodes of radio networks. The sets comprise information such as: transmit and receive point identities; cell identities; beam identities; frequency channels; channel bandwidth; and black lists. The sets may be defined at different levels, such as network and physical (PHY) level. A network mobility set, e.g., a new-radio (NR) mobility set may, be determined by the gNB, the cell, the UE, or another device. Multiple radio access network nodes and UEs may exchange mobility set information to achieve a distributed mobility solution. A UE may monitor its orientation relative to a TRP, e.g., via use of an onboard MEMS gyroscope, and alter its beamforming parameters in response to changes in orientation and/or changes in TRP connection strength. Cell selection and reselection for beam based networks may use Single Frequency Network (SFN) broadcast of initial access signals without beam sweeping.

Abstract: Disclosed herein are new radio (NR) Data link architecture options including, for example, NR radio bearer models, NR logical channel models, and MAC and HARQ models. Further described are packet flows mapping to data radio bearers (DRBs), and a new flow encapsulation protocol in the user plane. In some embodiments, DRBs with different quality of service (QoS) are pre-established, but not activated. This allows a given user equipment (UE) to use these DRBs for packet data network (PDN) flows without a large overhead. Pre-established DRBs can be an extension to default bearer concept with the decision of pre-establishment of DRBs based on UE capability, subscription profile, operation policy, installed apps, etc.

Abstract: Systems, methods, and instrumentalities are disclosed for Uplink operation in LTE unlicensed spectrum (LTE-U). A wireless transmit/receive unit (WTRU) may receive licensed assisted access (LAA) configuration information, e.g., for a first cell from a second cell. The first cell may be associated with operation in an unlicensed band, and the second cell may be associated with operation in a licensed band. The WTRU may determine whether a first subframe is a sounding reference signal (SRS) subframe for the first cell. If the first subframe is an SRS subframe for the first cell, the WTRU may determine SRS resources for the first subframe and determine whether the WTRU is triggered to transmit an SRS transmission in the first subframe. If it is determined the WTRU is triggered to transmit the SRS transmission in the first subframe, the WTRU may transmit the SRS transmission on the SRS resources for the first subframe.
