  • Patent number: 12063598
    Abstract: A device may obtain, through wireless signaling from a network, a time-domain wireless-resource allocation (TWRA) pattern allocated to the device by the network and corresponding to a future time interval (TTI) for which the device has not yet decoded corresponding control information. This enables the device to conduct wireless communications during the TTI using resources allocated according to the obtained TWRA pattern, without first having to decode control information to identify the TWRA pattern. The device may obtain the TWRA pattern by obtaining an indication from the network that the TWRA pattern remains associated with future wireless communications of the device until indicated otherwise by the network, and/or by transmitting to the network an indication of preferred parameters associated with the future wireless communications and the TWRA pattern, and/or by transmitting to the network a request to have the network change from a different TWRA pattern to the TWRA pattern.

  • Patent number: 12058548
    Abstract: Systems and methods for performing measurements of one or more cells during an small data transmission (SDT) procedure between a user equipment (UE) and a network when the UE is in a radio resource control (RRC) INACTIVE state are described herein. Beam and/or cell measurements taken during an SDT measurement period of the SDT procedure may be used to determine one or more respective cell qualities, among other possibilities. Beginnings and endings of the SDT measurement period, and the manner (timing) for taking measurements within the SDT measurement period, are also described. The cell qualities so determined can then be used to monitor, during the SDT measurement period, for a measurement event, which causes the UE to send a measurement report to the network having data determined using those cell qualities, and/or to send messaging intended to induce the network to change the RRC state of the UE.

  • Patent number: 12058689
    Abstract: An approach to reduce the signaling overhead for tracking reference signal (TRS) configuration signaling to idle and inactive user equipments (UEs) operating in a wireless communication system. Conventional signaling approaches require more bits that can be conveyed in the maximum system information block (SIB) message size. One proposed approach optimizes the signaling by removing unnecessary or redundant information, using a single TRS configuration to replace multiple configurations, size reduction in some fields, and the sharing of some fields across different TRS configurations. Another proposed approach uses an SIB message to carry the TRS configurations for a particular beam or subset of beams. These two proposed approaches may be combined to provide further optimization possibilities.

  • Patent number: 12058727
    Abstract: Systems and methods are provided for controlling behavior for overriding grants for channel state information (CSI) feedback. A user equipment (UE) may control override of a first grant of a first radio resource by a second grant of a second radio resource. The UE determines that the second radio resource at least partially overlaps with the first radio resource. The UE also determines a physical layer priority of the first grant of the first radio resource and the second grant of the second radio resource. The physical layer priority is based on at least one of the first grant of the first radio resource and the second grant of the second radio resource being configured for transmitting CSI feedback over a physical uplink shared channel (PUSCH) to a base station. The UE then generates a transmission according to the physical layer priority.
