Abstract
The present disclosure relates to a data transmission method and device. Said method comprises: determining, according to resource configuration information, 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; transmitting the preamble sequence by using the PRACH time-frequency resource, and transmitting data by using a PUSCH time-frequency resource determined according to the preamble sequence and the mapping relationship; and detecting a random access response message MsgB in a random access response window. In the present disclosure, a preamble sequence and data are sent at the same time, and after the preamble sequence and the data are sent, the detection and reception of random access response information MsgB to the base station can be performed, thereby realizing a random access between a terminal and the base station by means of two-step interaction, reducing the latency.
