用于配置授权小数据传输的带宽部分（BWP）切换
By enabling BWP handover triggered autonomously or by network commands in 5G wireless telecommunications systems, the signaling overhead and latency issues of small data transmission in the RRC_INACTIVE state are resolved, achieving efficient data transmission optimization and meeting the requirements of low power consumption and low data rate.

AI Technical Summary
In 5G wireless telecommunications systems, how can signaling overhead and latency be avoided when transmitting small data in RRC_INACTIVE state, especially when the configuration authorization (CG)-small data transmission (SDT) condition is invalid, and how can we autonomously switch to the dedicated bandwidth portion (BWP) to optimize the data transmission process?
The user equipment (UE) can initiate a handover to a dedicated BWP configured with CG-SDT via autonomous operation or network command. The handover can be performed using DCI or MAC CE signaling when TA, SSB validity, and UL resources change, thus optimizing the RA process and data transmission.
It reduces the signaling overhead and latency from RRC_INACTIVE to RRC_CONNECTED state, improves the efficiency and reliability of small data transmission, and meets the requirements of low power consumption and low data rate.
