Patent number: 12207291Abstract: Methods, systems, and apparatuses are described herein for beamforming based initial access, beam management, and beam based mobility designs for NR systems. Issues are identified and addressed related to one or more of initial access, control channel design, eMBB and URLLC mixing, and beam training. The methods, systems and apparatus may include a receiving scheduling information and a preemption indication via a DCI. In addition, there may be a detecting and decoding of the preemption indication, a determining of a HARQ feedback associated, and a sending, to a network node, of the HARQ feedback.Type: GrantFiled: June 27, 2024Date of Patent: January 21, 2025Assignee: InterDigital Patent Holdings, Inc.Inventors: Qing Li, Lakshmi R.

Patent number: 12150146Abstract: New radio download numerology allocation information may be obtained through master information block data, system information block data, radio resource control signals, or signals or a physical downlink numerology indication channel, and used along with a reference signal detected in a search space to obtain resource element positions in an antenna port reference signal in a resource block that belongs to a particular band slice according to a reference signal allocation scheme for a band slice numerology. A physical download control may then be decoded based upon one or more resource elements of the reference signal, allowing the connection of, e.g., an enhanced mobile broadband, massive machine type communication, or ultra-reliable/low-latency application to a communications network thereby. Alternatively, multiple physical downlink control channels may be blindly demodulated at each of a number calculated reference signal locations, and one channel selected based on passing a cyclic redundancy check.Type: GrantFiled: March 31, 2023Date of Patent: November 19, 2024Assignee: InterDigital Patent Holdings, Inc.Inventors: Allan Y.

The instructions include receiving, from a base station, configuration information indicating a set of channel state information interference channel measurement (CSI-ICM) resources for the WTRU. The configuration information indicates a period and an offset for the set of CSI-ICM resources. The instructions also include receiving, from the base station, downlink control information (DCI) indicating a subset of the set of CSI-ICM resources. The instructions further include measuring the subset of CSI-ICM resources. The instructions even further include transmitting feedback to the base station based on the subset of CSI-ICM resources.

Patent number: 11923939Abstract: 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.Type: GrantFiled: February 27, 2023Date of Patent: March 5, 2024Assignee: IPLA HOLDINGS INC.Inventors: Wei Chen, Pascal M.

Patent number: 11770821Abstract: 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.Type: GrantFiled: March 20, 2020Date of Patent: September 26, 2023Assignee: InterDigital Patent Holdings, Inc.Inventors: Qing Li, Guodong Zhang, Pascal M.
