1. A data transmission method applicable to a terminal, the method comprising:
determining a preamble sequence, a physical random access channel PRACH time-frequency resource, a physical uplink shared channel PUSCH time-frequency resource set, and a mapping relationship between the preamble sequence and PUSCH time-frequency resources in the PUSCH time-frequency resource set, based on resource configuration information;
transmitting the preamble sequence by using the PRACH time-frequency resource, and transmitting the data by using a PUSCH time-frequency resource determined from the preamble sequence and the mapping relationship; and
detecting a random access response message MsgB in a random access response window.
