  • 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.

  • Publication number: 20210168645
    Abstract: Logical Channel Prioritization (LCP) may be enhanced by accounting for Quality of Service (QoS) attributes of single hop and multi-hop paths. QoS attributes may be communicated as a QoS budget comprising a number of attributes, or as a single composite QoS “resistance” factor that quantifies the compounded impact of number of hops, latency, load conditions, and the like. The QoS budget or resistance may dynamically adjusted, and may be used by LCP to provide differentiated uplink resource allocation to data of the bearer or logical channel subject to different transmission paths between the transmitter and the receiver, for example. QoS budget and resistance information may be used to, e.g., enhance Buffer Status Report (BSR) and Scheduling Request (SR) operations.

  • 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: 10904895
    Abstract: Channel state information is reported in periodic and aperiodic reports for multiple component carriers or serving cells. Channel state information may be reported for a subset of aggregated downlink carriers or serving cells. For an aperiodic report, the carrier(s)/serving cell(s) for which channel state information is reported are determined based on the request for the aperiodic report. When a CQI/PMI/RI report and a HARQ ACK/NACK report coincide in a subframe, the HARQ ACK/NACK report is transmitted on PUCCH, and the CQI/PMI/RI report is transmitted on PUSCH.
