  • Publication number: 20240267808
    Abstract: Methods, systems, and devices for wireless communications are described. A UE operating in an NTN may receive an indication of coverage information for a first cell associated with the NTN. The coverage information may indicate a coverage area supported by the first cell for wireless communications. The UE may transmit, based on location information of the UE and the coverage information, a message indicating a timing information associated with a measurement-based handover for the UE from the first cell to a second cell associated with the non-terrestrial network. For example, the message may include a recommendation for the UE to perform a non-measurement-based handover or an indication that the UE cannot complete the measurement-based handover before leaving the coverage area of the first cell.

  • Publication number: 20240064679
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.
