Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a method for sending system information, a network device, and a terminal device. Background Art

[0002] In the 5G communication system, the cells in the network can be divided into cells where terminal devices can reside and cells where terminal devices cannot reside (for example, barred cells, non-independent working cells, etc.). At this stage, network equipment sends the same system information in these two types of cells. However, for cells where terminal devices cannot reside, sending the same system information as cells where terminal devices can reside will send some unnecessary information (for example, cell selection information, scheduling information of other system information, etc.), which will in turn generate unnecessary signaling overhead.

[0003] Therefore, how to overcome the unnecessary signaling overhead generated when the terminal device sends system information in a cell where the terminal device cannot reside is an issue that needs to be solved urgently. Summary of the invention

[0004] An embodiment of the present application provides a method for sending system information, a network device, and a terminal device. The network device sends a first type of system information for enabling the terminal device to discover the cell in a cell where the terminal device cannot reside, and sends a second type of system information for enabling the terminal device to access the cell in a cell where the terminal device can reside. Furthermore, indication information can be sent to the terminal device to indicate whether the system information sent by the cell is the first type of system information or the second type of system information, thereby avoiding unnecessary signaling overhead during the sending and receiving of the system information.
