SYNCHRONIZATION AND FEEDER LINK DELAY DRIFT IN NON-TERRESTRIAL NETWORK COMMUNICATIONS

Various solutions for synchronization and feeder link delay drift in non-terrestrial network (NTN) communications are described. An apparatus (e.g., a UE) receives from a network information of a common timing advance (TA), a common TA drift rate, and a common TA drift rate variation at a reference...

Summary:Various solutions for synchronization and feeder link delay drift in non-terrestrial network (NTN) communications are described. An apparatus (e.g., a UE) receives from a network information of a common timing advance (TA), a common TA drift rate, and a common TA drift rate variation at a reference time. The apparatus determines a TA delay based on the information. The apparatus then performs NTN communications with the network with the TA delay accounted for.
