基于定时器切换带宽部分的方法、终端设备和网络设备
By generating and receiving instruction information, terminal devices and network devices adjust the BWP to deactivate the timer, which solves the data interruption problem during bandwidth switching, realizes continuous transmission of non-dynamically scheduled resources, and improves the reliability of data transmission.

AI Technical Summary
During bandwidth switching, existing technologies cause data transmission interruptions, especially when the BWP timer expires after the semi-permanent scheduling resource is activated, and the UE switches to the default or initial BWP, interrupting SPS transmission.
Terminal devices and network devices determine whether to stop, start, or adjust the BWP deactivation timer by generating and receiving indication information to avoid data interruption. The indication information can be a CS-RNTI scrambled PDCCH or RRC reconfiguration message. The activation or deactivation of the scheduling resource is determined based on the NDI in the HARQ information.
This effectively avoids data interruptions during bandwidth switching, ensures the continuity of non-dynamically scheduled resources, and improves the reliability of data transmission.
