摘要:
Various solutions for timing and frequency synchronization in non-terrestrial network (NTN) communications with respect to user equipment and network nodes are described. An apparatus may receive a reference time signaled by a network node. The apparatus may measure a received time of a downlink message from the network node. The apparatus may estimate a propagation delay according to the reference time and the received time. The apparatus may perform a timing pre-compensation according to the propagation delay.
