  • Patent number: 12360663
    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.

  • Publication number: 20250227459
    Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, informing and/or requesting the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

  • Patent number: 12356458
    Abstract: Methods and systems to enhance NR RACH procedure to accommodate non-terrestrial networks (NTN) are disclosed. The length of the RAR window may be extended. A NTN-RNTI associated with the time-frequency resources used for the PRACH preamble may be used to scramble the CRC of DCI used for downlink assignment in the RAR. The DCI content may include information on the associated PRACH preamble to assist the UE in distinguishing between RARs generated as a response to PRACH preambles transmitted by different UEs from different system frames. The NTN-RNTI may contain information on the system frames when the UE sends the PRACH preamble. The RA-RNTI associated with the time-frequency resources used for the PRACH preambles transmitted from different frames may be used to scramble different subsets of the CRC of the DCI format 1_0 to assist the UE in distinguishing between RARs generated in response to the different PRACH preambles.

  • Publication number: 20250220614
    Abstract: This application relates to wireless communications, including methods and apparatus to manage uplink (UL) transmit switching with multiple timing advance groups (TAGs) for wireless devices. A wireless device is configured to use multiple carriers selected from a set of available carriers that can be associated with different TAGs. When a second set of carriers, used after switching from a first set of carriers, includes carriers that belong to different TAGs, the wireless device determines whether to transmit on one or more first uplink transmission occasions for each of the carriers in the second set of carriers based on whether a first UL transmission occasion for at least one carrier overlaps a switching gap time period. The wireless device can disallow transmission on first UL transmission occasions of one or more carriers to accommodate the overlap.
