1. A method performed by a terminal device, the method comprising:
determining a random access occasion based at least in part on random access configuration information for a non-terrestrial network; and
transmitting a preamble to a network node in the non-terrestrial network, according to the determined random access occasion, wherein the random access configuration information indicates configuration of two consecutive random access occasions so that a time interval between the two consecutive random access occasions is equal to or larger than an interval threshold.
