  • Publication number: 20210126749
    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).

  • Patent number: 10965523
    Abstract: A provisioning system receives network element information from a wireless communication network that characterizes a virtual network element. The provisioning system determines that the virtual network element is active and that a provisioning data link is not operational between the virtual network element and the provisioning system. The provisioning system determines a network address for the virtual network element. The provisioning system exchanges network signaling with the virtual network element using the network address to establish the provisioning data link. The provisioning system transfers provisioning data to the virtual network element over the provisioning data link.

  • Publication number: 20210076445
    Abstract: The present application is at least directed to an apparatus on a network including a non-transitory memory including instructions stored thereon for re-establishing a remote radio control (RRC) connection with a base station. The apparatus also includes a processor, operably coupled to the non-transitory memory, capable of executing an instruction of determining a radio link failure has occurred between a first bandwidth part (BWP) of the apparatus tuned to a base station. The processor also executes the instruction of initiating a random access (RA) procedure. The processor also executes the instruction of determining whether a configured contention-based physical random access channel (PRACH) resource overlaps with the first BWP. The process further executes the instruction of transmitting a RA preamble including the configured contention-based PRACH resource to the base station. The processor even further executes the instruction of receiving a RA response from the base station.

  • Patent number: 10932278
    Abstract: It is recognized herein that, in some cases, URLLC transmissions may preempt a scheduled eMBB transmission. Thus, in accordance with one embodiment, resources are allocated for URLLC data transmission in a manner that minimally impacts eMBB data transmissions. In an example code block groups are configured for efficient multi-bit A/N feedback. Multi-bit A/N methods are disclosed with and without explicit resource allocation. Various preemption mechanisms are also described herein including, for example, puncturing, dropping the tail end of a transport block, and increasing rate matching.

  • Patent number: 10924171
    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.

  • Publication number: 20210045181
    Abstract: Switching between Orthogonal Multiple Access (OMA) and Non-Orthogonal Multiple Access (NOMA) modes of a user equipment (UE) can be determined and indicated by a gNB to a UE at an RRC connected state using one or more of the following schemes: at an RRC (Radio Resource Control) layer with an RRC configuration message, at a MAC (Medium Access Control) layer with MAC CE (MAC control element) signaling, at a PHY (Physical) layer with DCI (Downlink Control Information) signaling, jointly with RRC configuration and DCI signaling, and/or jointly with RRC configuration and MAC CE signaling. The OMA or NOMA mode that the UE operates after the transition may be requested by the UE, indicated by the gNB, and/or may be based on one or more rules for OMA-NOMA switching.

  • Patent number: 10880868
    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.

  • Publication number: 20200287678
    Abstract: In NR, a slot structure of a UE may be dynamic due the number of symbols of PDCCH and whether the slot has UL data, among other considerations. Additionally, to support multi-TRP/multi-panel/multi-BWP operation, a UE may be configured with multiple TRSs, and when a UE needs to receive multiple TRSs in the same slot, efficient signaling of the TRSs is important because of the high overhead involved. During a transmission, a UE may need to do beam switching when there is a beam failure, but existing systems do not have mechanisms for the UE to synchronize time and frequency with a new beam. Further, when a UE switches to a new beam, the effect on scheduled TRS transmission for old beams is unclear. Fine frequency and time tracking may also be required during an initial access procedure. Existing NR systems do not address how a UE may perform time and frequency tracking during an initial access procedure. Additionally, URLLC data may need to be transmitted to a UE immediately in an NR system.

  • Publication number: 20200267753
    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.
