User terminal and radio communication method
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.
1. A terminal comprising:
a receiver that receives information related to a synchronization signal block index indicated by using a bitmap, by higher layer signaling; and
a controller that controls a reception of a synchronization signal block based on the information related to the synchronization signal block index.
2. The terminal according to claim 1 , wherein the information related to the synchronization signal block index comprises information notified by using the bitmap, related to whether or not a plurality of synchronization signal block indexes is transmitted.
3. The terminal according to claim 2 , wherein a number of bits needed for transmitting the information that is notified by the bitmap is determined based on a maximum number of synchronization signal blocks per frequency band.
4. The terminal according to claim 3 , wherein each synchronization signal block index corresponds to a separate time index.
5. The terminal according to claim 2 , wherein each synchronization signal block index corresponds to a separate time index.
6. The terminal according to claim 1 , wherein each synchronization signal block index corresponds to a separate time index.
7. A radio communication method comprising:
receiving information related to a synchronization signal block index indicated by using a bitmap, by higher layer signaling; and
controlling reception of a synchronization signal block based on the information related to the synchronization signal block index.
8. A base station comprising:
a transmitter that transmits information related to a synchronization signal block index indicated by using a bitmap, by higher layer signaling; and
a controller that controls a transmission of a synchronization signal block based on the information related to the synchronization signal block index.
9. A system comprising a terminal and a base station, wherein:
the terminal comprises:
a receiver that receives information related to a synchronization signal block index indicated by using a bitmap, by higher layer signaling; and
a first controller that controls a reception of a synchronization signal block based on the information related to the synchronization signal block index; and
the base station comprises:
a transmitter that transmits the information related to the synchronization signal block index by higher layer signaling; and
a second controller that controls a transmission of the synchronization signal block based on the information related to the synchronization signal block index.
