Summary:In a non-terrestrial network, the delay in reception time may prevent reception of a random access preamble. A combination of increasing transmit power and changing the timing with which the random access preamble is transmitted may enable reception of the random access preamble. One or more criteria may be used to determine whether the timing advance value with which the random access preamble is transmitted should be changed before retransmission is attempted.
