无线通信的方法、终端设备和网络设备
By indicating the SDT function support status in the cell MIB, terminal devices prioritize camping on cells that support SDT, thus solving the problem of frequent state switching after SDT cells are disconnected from the network and achieving low-power and high-efficiency data transmission.

AI Technical Summary
Technical Problem
After a terminal device disconnects from an SDT cell, it may revert to a cell that does not support small packet data transmission, leading to frequent entry and exit from the connection state, increasing network interaction signaling and terminal power consumption.
Method used
Terminal devices determine whether SDT function is supported by receiving the MIB information of the cell, avoid receiving SIB1, prioritize camping on cells that support SDT function, and reduce unnecessary signaling processing.
Benefits of technology
It improves the efficiency of small packet data transmission in the RRC deactivation state of terminal devices, reduces terminal power consumption, and enhances user experience.

Abstract
本申请提供了一种无线通信的方法、终端设备和网络设备，终端设备可以基于第一小区的MIB中包括的第一信息，确定第一小区是否支持SDT功能。也即，在SDT小区发生脱网后，可以基于第一小区的MIB及时确定第一小区是否支持SDT功能，从而在恢复网络过程中可以尽可能的驻留到支持SDT功能的小区，这样就可以继续利用SDT功能的优点，在RRC去激活状态下进行小包数据传输业务，降低终端功耗，提升了用户使用体验。该无线通信的方法，包括：终端设备接收第一小区的MIB，其中，该第一小区的MIB包括第一信息，该第一信息用于指示该第一小区是否支持SDT功能。
