Abstract
A future radio communication system (NR) appropriately detects a synchronization signal transmitted in a flexible time and frequency resource. A user terminal includes: a reception section that receives a synchronization signal and/or a common control information channel transmitted in a flexible resource; and a control section that recognizes a resource position at which the synchronization signal is transmitted, based on the synchronization signal or the common control information channel.
Claims5
A terminal comprising:
- a receiver that receives a synchronization signal, and receives a broadcast channel, in a resource located at a predetermined position relative to a resource for the synchronization signal;
- and
- a processor that determines an index, which indicates a time resource for the synchronization signal and the broadcast channel, based on the broadcast channel,
- wherein, in a Radio Resource Control (RRC) connected mode, the receiver receives measurement-object information that indicates a measurement frequency of the synchronization signal and a measurement timing of the synchronization signal.
A radio communication method for a terminal, comprising:
- receiving a synchronization signal, and receiving a broadcast channel, in a resource located at a predetermined position relative to a resource for the synchronization signal;
- determining an index, which indicates a time resource for the synchronization signal and the broadcast channel, based on the broadcast channel;
- and
- in a Radio Resource Control (RRC) connected mode, receiving measurement-object information that indicates a measurement frequency of the synchronization signal and a measurement timing of the synchronization signal.
A base station comprising:
- a processor that controls the base station;
- and
- a transmitter that transmits a synchronization signal, and transmits a broadcast channel, in a resource located at a predetermined position relative to a resource for the synchronization signal,
- wherein an index, which indicates a time resource for the synchronization signal and the broadcast channel, is based on the broadcast channel, and
- wherein, in a Radio Resource Control (RRC) connected mode, the transmitter transmits measurement-object information that indicates a measurement frequency of the synchronization signal and a measurement timing of the synchronization signal.
A system comprising a base station and a terminal, wherein:
- the base station comprises:
- a transmitter that transmits a synchronization signal, and transmits a broadcast channel;
- and
- the terminal comprises:
- a receiver that receives the synchronization signal, and receives the broadcast channel, in a resource located at a predetermined position relative to a resource for the synchronization signal;
- and
- a processor that determines an index, which indicates a time resource for the synchronization signal and the broadcast channel, based on the broadcast channel,
- wherein, in a Radio Resource Control (RRC) connected mode, the receiver receives measurement-object information that indicates a measurement frequency of the synchronization signal and a measurement timing of the synchronization signal.
