AI Technical Summary
Technical Problem
There is no clear solution for the behavior of terminals when the secondary cell group (SCG) is in deactivated state, which makes the mechanism for restoring the SCG to the activated state unclear and affects data transmission efficiency.
Method used
A RACH method and apparatus are provided, which perform a beam failure recovery (BFR) or SCG activation RACH process in an SCG deactivated state, including selecting appropriate RACH resources and priorities to achieve SCG activation and data transmission.
Benefits of technology
It improves the efficiency of the SCG activation process and the reliability of data transmission, reduces the power consumption of the terminal, and ensures that the data transmission capability can be quickly restored in the SCG deactivation state.
