Abstract: A preamble sequence mapping method and a terminal are provided. The method includes: determining, by a terminal according to a rule for sorting T second preamble sequences, a target index of a second preamble sequence. The T second preamble sequences are all or some of sequences obtained after the terminal performs code-division on M first preamble sequences by using Q Orthogonal Cover Codes (OCCs). The method further includes establishing, by the terminal based on the target index of the second preamble sequence, mapping to a Synchronization Signal and Physical Broadcast Channel block (SSB). Q is an integer greater than or equal to 1. M is an integer greater than or equal to 1. T is an integer greater than or equal to 2.
