AI Technical Summary

Technical Problem

In the existing two-step random access process, the random access preamble is not mapped to a valid physical uplink shared channel resource, which makes it impossible to generate the MsgA payload and affects the reliability of the random access process.

Method used

If the random access preamble is not mapped to a valid physical uplink shared channel resource, the uplink data is generated by generating the first uplink data and storing it in the MsgA buffer, and then using the PUSCH resource set associated with the random access preamble or the backoff random access response to generate uplink data.

Benefits of technology

This ensured the smooth operation of the random access process and improved its reliability.
