Abstract
A base station that can transmit a synchronization signal at a predetermined transmission interval in a plurality of cycles includes a processor configured to continuously transmit the synchronization signal in a plurality of radio signals; and control radio measurement of a mobile station connected to the base station such that the mobile station detects the synchronization signal under a condition in accordance with second information that has been scaled by using first information.
Claims13
A base station that can transmit a synchronization signal at a predetermined transmission interval in a plurality of cycles, the base station comprising:
- a processor configured to:
- continuously transmit the synchronization signal in a plurality of radio signals;
- and
- control a radio measurement cycle of radio measurement of a mobile station connected to the base station such that the mobile station detects the synchronization signal under a condition in accordance with second information associated with the radio measurement cycle, the second information being controlled by information for configuring the radio measurement included in first information that is transmitted from the base station to the mobile station, wherein
- the radio measurement cycle is a cycle obtained by multiplying a measurement cycle as a criterion by N (N is an integer multiple).
A mobile station that can receive a synchronization signal transmitted from a base station at a predetermined transmission interval in a plurality of cycles, the mobile station comprising:
- a processor configured to:
- continuously receive the synchronization signal;
- and
- detect the synchronization signal under a condition in accordance with second information associated with a radio measurement cycle of radio measurement, the second information being controlled by information for configuring the radio measurement included in first information that is transmitted from the base station to the mobile station, and perform radio measurement, wherein
- the radio measurement cycle is a cycle obtained by multiplying a measurement cycle as a criterion by N (N is an integer multiple).
A communication system comprising:
- a base station that can transmit a synchronization signal at a predetermined transmission interval in a plurality of cycles;
- and
- a mobile station that is connected to the base station, wherein
- the base station includes a processor is configured to:
- continuously transmit the synchronization signal in a plurality of radio signals;
- and
- control a radio measurement cycle of radio measurement of a mobile station connected to the base station such that the mobile station detects the synchronization signal under a condition in accordance with second information associated with the radio measurement cycle, the second information being controlled by information for configuring the radio measurement included in first information that is transmitted from the base station to the mobile station, wherein
- the radio measurement cycle is a cycle obtained by multiplying a measurement cycle as a criterion by N (N is an integer multiple).
A communication method used in a communication system that includes a base station that can transmit synchronization information at a predetermined transmission interval in a plurality of cycles and a mobile station that is connected to the base station, the communication method comprising:
- transmitting continuously the synchronization information in a plurality of radio signals;
- and
- controlling a radio measurement cycle of radio measurement of the mobile station connected to the base station such that the mobile station detects the synchronization signal under a condition in accordance with second information associated with the radio measurement cycle, the second information being controlled by information for configuring the radio measurement included in first information that is transmitted from the base station to the mobile station, wherein
- the radio measurement cycle is a cycle obtained by multiplying a measurement cycle as a criterion by N (N is an integer multiple).
