Abstract
An apparatus and method for setting a guard band with respect to an asynchronous Base Station (BS) in a broadband wireless communication system are provided. The BS includes a controller for generating a control signal to set a guard band when a time offset occurs between BSs; a mapper for mapping and outputting transmit data to a band, excluding the guard band, of a unique band of the BS according to the control signal; and an operator for multicarrier-modulating data fed from the mapper.
Claims14
A base station in a wireless communication system, comprising:
- a transceiver;
- and
- a controller configured to:
- transmit, to a mobile station, a signal using a band in which a guard band is set, wherein a size of the guard band is pre-determined,
- detect a time offset value representing a time offset between a base station and another base station,
- adjust the size of the guard band based on table information indicating a relationship between the time offset value and a size of the guard band,
- adjust a length of a transmission period based on the adjusted size of the guard band and an amount of control information that is included in the signal, and
- transmit, to the mobile station, a signal using the band in which the guard band with the adjusted size is set during the transmission period.
A mobile station in a wireless communication system, comprising:
- a transceiver;
- and
- a controller configured to:
- receive, from a base station, a signal using a band in which a guard band is set, wherein a size of the guard band is pre-determined, and
- receive, from the base station, a signal using the band in which the guard band with an adjusted size is set during a transmission period,
- wherein the size of the guard band is adjusted, by the base station, based on table information indicating a relationship between a time offset value and a size of the guard band,
- wherein the time offset value represents a time offset between the base station and another base station, and
- wherein a length of the transmission period is adjusted, by the base station, based on the adjusted size of the guard band and an amount of control information that is included in the signal.
A method for operating a base station in a wireless communication system, the method comprising:
- transmitting, to a mobile station, a signal using a band in which a guard band is set, wherein a size of the guard band is pre-determined;
- detecting a time offset value representing a time offset between the base station and another base station,
- adjusting the size of the guard band based on table information indicating a relationship between the time offset value and a size of the guard band;
- adjusting a length of a transmission period based on the adjusted size of the guard band and an amount of control information that is included in the signal;
- and
- transmitting, to the mobile station, a signal using the band in which the guard band with the adjusted size is set during the transmission period.
A method for operating a mobile station in a wireless communication system, comprising:
- receiving, from a base station, a signal using a band in which a guard band is set, wherein a size of the guard band is pre-determined;
- and
- receiving, from the base station, a signal using the band in which the guard band with an adjusted size is set during a transmission period,
- wherein the size of the guard band is adjusted, by the base station, based on table information indicating a relationship between a time offset value and a size of the guard band,
- wherein the time offset value represents a time offset between the base station and another base station, and
- wherein a length of the transmission period is adjusted, by the base station, based on the adjusted size of the guard band and an amount of control information that is included in the signal.
