6G-NTN

In scenarios or cases where no feeder link is available, it is still critical and beneficial to apply direct communication over satellite(s) for supporting communication between two or more UEs, e.g., to support an emergency service for public safety. In this scenario, only NTN service network involvement is considered. One or more UEs of type, whether handheld or maritime, may be connected directly under the same satellite for communication exchange. There are also scenarios where more than one satellite may be involved, i.e., connection users in coverage areas of nearby satellites being connected via Inter Satellite Links (ISL). In general, the direct connection of users without feeder link access is a new scenario to be considered in the 6G NTN context.
Any UE requests resilience against interruptions and stable communication, whatever the incident in the feeder station is.
