1. A random access preamble configuration method applicable to a satellite network, comprising:
receiving, by a receiving apparatus, first indication information, wherein the first indication information comprises indication information used to identify a random access preamble location offset at a physical random access channel PRACH occasion; and
transmitting, by the receiving apparatus, a random preamble based on the first indication information, wherein the random preamble comprises a sequence part and a guard time,
wherein the first indication information further comprises at least one first sequence number, wherein the first sequence number is used to indicate random access configuration information associated with a random access preamble without a cyclic prefix; and
the receiving apparatus determines format information of the random access preamble without the cyclic prefix based on the random access configuration information.
