Data transmission method and device, user equipment, base station, communication system and storage medium

A data transmission method, comprising:

• sending a mapping relationship between a configuration of a physical uplink shared channel (PUSCH) resource and random-access preamble sequence configuration information;
• receiving a message containing a physical random-access channel (PRACH) resource and the PUSCH resource;
• acquiring the random-access preamble sequence configuration information of the PRACH resource from the message;
• according to the mapping relationship and the random-access preamble sequence configuration information, determining the configuration of the PUSCH resource;
• and
• acquiring information in the PUSCH resource according to the configuration of the PUSCH resource.

A user equipment (UE) for data transmission, comprising a processor and a memory, wherein:

• the memory is configured to store instructions;
• and
• the processor is configured to read the instructions to perform:
• obtaining a mapping relationship between a configuration of a physical uplink shared channel (PUSCH) resource and random-access preamble sequence configuration information from a base station;
• determining the random-access preamble sequence configuration information based on the mapping relationship;
• mapping a preamble sequence onto a physical random-access channel (PRACH) resource according to the random-access preamble sequence configuration information;
• and
• sending a message containing the PRACH resource and the PUSCH resource to the base station.
