1. A method performed by a wireless device for communication in a non-terrestrial network, NTN, comprising at least a first non-terrestrial network node and a second non-terrestrial network node, the method comprising:
determining an estimated location of the wireless device;
obtaining first location information associated with the first non-terrestrial network node and second location information associated with the second non-terrestrial network node;
calculating an estimated signal time arrival difference based on the location of the wireless device, the first location information, and the second location information;
using the estimated signal time arrival difference to provision an NTN-specific synchronization signal/physical broadcast channel, SS/PBCH, block measurement timing configuration, NTN-SMTC and
using the NTN-SMTC to detect one of the first non-terrestrial network node and second non-terrestrial network node.
