Abstract
An apparatus for use in a base station capable of checking whether a frequency is illegally used in a wireless communication system are provided. Operations of the base station for checking whether the frequency is illegally used includes setting a silence interval in which a resource is not allocated to a terminal, using silence interval setting information provided from a system manager; when the silence interval arrives, measuring RSSI; and transmitting the RSSI to the system manager to examine at least one of a frequency illegal use and a reception path error using the RSSI.
Claims17
A method of a base station for checking whether a frequency is illegally used in a wireless communication system, the method comprising:
- receiving, from a system manager, a silence interval setting signal comprising silence interval setting information;
- setting a silence interval in which a resource is not allocated to a terminal, using the silence interval setting information received from a system manager, and wherein the setting of the silence interval comprises:
- determining the silence interval in which the resource is not allocated to terminals, using a GPS time and the silence interval setting information provided from the system manager and
- determining an uplink interference power report period and the number of the report repetitions using the GPS time and the silence interval setting information;
- when the silence interval starts, measuring Received Signal Strength Indication (RSSI);
- and
- transmitting the RSSI to the system manager to examine at least one of a frequency illegal use and a reception path error using the RSSI,
- wherein the RSSI measured in the silence interval is recognized as an uplink interference power.
An apparatus of a base station for checking whether a frequency is illegally used in a wireless communication system, the apparatus comprising:
- a wired interface configured to transmit and receive signals to and from a system manager connected over a wired network, wherein the received signals comprise a silence interval setting signal, the silence interval setting signal comprising silence interval setting information;
- a scheduler configured to set a silence interval in which a resource is not allocated to a terminal, using the silence interval setting information received from the system manager via the wired interface, and transmit Received Signal Strength Indication (RSSI) measured at an RSSI measurer in the silence interval, to the system manager;
- the RSSI measurer configured to measure the RSSI when the silence interval arrives;
- and
- a GPS receiver configured to check a GPS time based on a GPS signal, wherein the scheduler is configured to determine the silence interval an uplink interference power report period and the number of report repetitions using the GPS signal output from the GPS receiver and the silence interval setting information provided via the wired interface, and wherein the RSSI measured in the silence interval is recognized as an uplink interference power.
A wireless communication system for examining whether a frequency is illegally used, comprising:
- a system manager configured to transmit silence interval setting information to at least one base station;
- the at least one base station configured to set a silence interval in which a resource is not allocated to a terminal, using the silence interval setting information, and when the silence interval arrives, measure Received Signal Strength Indication (RSSI) and transmit the RSSI to the system manager;
- and
- the system manager configured to examine at least one of frequency illegal use and a reception path error using the RSSI received from the at least one base station,
- wherein the RSSI measured in the silence interval is recognized as an uplink interference power, and wherein the at least one base station is configured to determine the silence interval, an uplink interference power report period, and the number of report repetitions using a GPS time and the silence interval setting information provided from the system manager.
