Abstract

For the purpose of properly controlling communication using a number of cells including cells that use different numerologies than existing LTE systems, a user terminal that communicates by using a number of cells including a first cell and a second cell has a receiving section that receives, from the first cell, information about synchronization between the first cell and the second cell and/or information about a configuration of a synchronization signal block in the second cell, and a control section that controls a processes for connecting with the second cell based on the information about synchronization and/or the information about the configuration of the synchronization signal block.

Claims

1-6. -6. (canceled)

7. A terminal comprising:

a receiving section that receives information about an index of a synchronization signal block by higher layer signaling; and

a control section that controls reception of the synchronization signal block based on the information about the index of the synchronization signal block.

8. The terminal according to claim 7, wherein the information about the index of the synchronization signal block is information about transmission or non-transmission of each of a plurality of synchronization signal blocks, indicated by using a bitmap.

9. The terminal according to claim 8, wherein a number of bits required for indication by using the bitmap is determined based on a maximum number of synchronization signal blocks per frequency band.

10. The terminal according to claim 7, wherein indexes of respective synchronization signal blocks are associated with different time indexes.

12. The terminal according to claim 8, wherein indexes of respective synchronization signal blocks are associated with different time indexes.

13. The terminal according to claim 9, wherein indexes of respective synchronization signal blocks are associated with different time indexes.

11. A radio communication method comprising:

receiving information about an index of a synchronization signal block by higher layer signaling; and

controlling reception of the synchronization signal block based on the information about the index of the synchronization signal block.
