In this case, if the RRM-SSB is used to directly notify the UE of the frequency position of the next sync-raster with CD-SSB, it will greatly reduce the time for the UE to search for CD-SSB one by one. SSB to notify the UE of the frequency position of the sync-raster where the SSB defined by the next cell is not yet relevant

Embodiment Construction

[0097] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to specific embodiments and accompanying drawings.

[0098] Such as figure 1 As shown, an embodiment of the present invention provides an information indication method applied to a base station, including:

[0099] Step 101: Use the predetermined parameters of the physical broadcast channel PBCH in the first system synchronization block SSB to indicate whether the first SSB has associated minimum remaining system information RMSI, or indicate that the first SSB has no associated minimum remaining system information RMSI and the first SSB 2. Frequency offset information of the synchronization grid where the SSB is located;

[0100] Wherein, the second SSB refers to the SSB associated with the RMSI.

[0101] Here, it may be indicated according to the value of the predetermined parameter of the PBC...

Abstract

The present invention provides an information indication, a determination method, a terminal and a base station, and solves the problem that there is currently no relevant solution on how to use a non-cell-defined SSB to notify the UE of the frequency position of the sync-raster where the next cell-defined SSB is located. The present invention includes: using the predetermined parameters of the PBCH in the first SSB to indicate whether the first SSB has an associated RMSI, or to indicate that the first SSB has no associated RMSI and the frequency offset information of the synchronization grid where the second SSB is located; wherein , the second SSB refers to the SSB of the associated RMSI. The present invention solves the problem that there is no specific method to use the non-cell-defined SSB to notify the UE of the frequency position of the sync-raster where the next cell-defined SSB is located.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to an information indication and determination method, a terminal and a base station. Background technique [0002] In a new generation of radio air interfaces, a system synchronization block (SSB for short) sent from a base station may or may not carry associated remaining minimum system information (RMSI for short). If an SSB has an associated RMSI, it is called a cell-defining SSB (CD-SSB). If an SSB has no associated RMSI, the SSB is used for radio resource management (radio resource management, RRM for short) measurement, which is called RRM-SSB here. CD-SSB must transmit at frequency positions defined as sync-rasters. The RRM-SSB can be transmitted at a common resource block (common resource block, CRB for short) frequency position, and can also be transmitted at a sync-raster frequency position. At the same time, the frequency of the sync-raster ...
