  • Patent number: 11923939
    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.

  • Patent number: 11770821
    Abstract: Current approaches to transmitting uplink data in a network often require resources to be granted. In an example, a node or apparatus may configure a plurality of devices to operate in a grant-less mode in accordance with a respective grant-less access allocation, such that, when the plurality of devices transmit messages uplink in the network, the messages are transmitted using frequency resources defined by the respective grant-less access allocation, and the plurality of devices transmit the messages without being granted access to transmit the messages, so as to operate in the grant-less mode.

  • Patent number: 11765603
    Abstract: It is recognized herein that as the number of transmit antennas in cellular systems (e.g., NR or 5G systems) increase, the Channel State information (CSI) feedback overhead may increase to unacceptable levels, and the current CSI feedback might not support beamforming training for NR. Embodiments described herein provide an enhanced and more efficient design for Channel State Information feedback as compared to current approaches.
