  • Patent number: 12245253
    Abstract: Disclosed are methods and systems to coordinate resource allocation between two UEs for sidelink communication. A receiving UE receiving sidelink communication from a transmitting UE may configure coordination resources used to coordinate sidelink communication between the two UEs. The receiving UE may receive from the transmitting UE data indicating resources reserved and intended to be used by the transmitting UE to transmit sidelink data to the receiving UE. The receiving UE may determine a coordination message used to indicate whether the resources reserved by the transmitting UE are available for use by the receiving UE to receive the sidelink data from the transmitting UE. The receiving UE may determine resources from the coordination resources to be used to carry the coordination message and may transmit the coordination message carried on the selected resources to indicate to the transmitting UE whether to use the reserved resources for the sidelink data.

  • Publication number: 20250070863
    Abstract: A user equipment (UE), a base station (e.g., next generation NodeB (gNB)), or other network component can operate to configure a beam failure recovery (BFR) timing based on a time offset and a number of symbols in a BFR procedure, as well as enable beam switching and bandwidth part (BWP) switching to be correlated. A beam failure recovery request (BFRQ) can be processed or transmitted in response to a detection of a beam failure. A beam failure recovery response (BFRR) can be generated via a physical downlink control channel (PDCCH) based on at least four slots after the BFRQ and a time offset for a non-terrestrial network (NTN).

  • Publication number: 20250068326
    Abstract: A gesture-based text entry user interface for an Augmented Reality (AR) system is provided. The AR system detects a start text entry gesture made by a user of the AR system, generates a virtual keyboard user interface including a virtual keyboard having a plurality of virtual keys, and provides to the user the virtual keyboard user interface. The AR system detects a hold of an enter text gesture made by the user. While the user holds the enter text gesture, the AR system collects continuous motion gesture data of a continuous motion as the user makes the continuous motion through the virtual keys of the virtual keyboard. The AR system detects a release of the enter text gesture by the user and generates entered text data based on the continuous motion gesture data.
