  • Publication number: 20210185681
    Abstract: Techniques for congestion management in a communication network are contemplated. For example, a wireless transmit receive unit (WTRU) may include a Radio Resource Control (RRC) layer and a Non-Access Stratum (NAS) layer. The RRC layer may receive an indication for a service, for example from the NAS. The indication may be interpreted as a request for the particular service indicated. For example, the indicated service may correspond to at least one of: a mobile originated (MO) voice communication, a circuit switched fallback (CSFB) supplementary service (SS), or a MO short message service (SMS). The RRC layer may receive a signal from a network indicating that one or more services provided by the network are allowed. The RRC layer may send a connection request to the network for the service sought by the NAS if that service is one of the one or more services allowed.

  • Publication number: 20210175945
    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: The present application at least describes a frame structure in new radio. The frame structure includes a self-contained transmission time interval. The transmission time interval includes a control information region including plural beams. The interval also includes a downlink transmission channel region including plural beams. The frame structure is configured for downlink control information to be swept through the time interval. The frame structure is also configured for an uplink or downlink grant resource subsequently to be swept through the time interval. The present application is also directed to a method for configuring user equipment.

  • 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: 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: 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.

  • Patent number: 10856221
    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.
