Abstract
A method and apparatus for controlling a Transmit power (TX power) of an indoor Base Station (BS) in a broadband wireless communication system. An operation of the indoor BS includes receiving received channel quality information on the indoor BS from at least one Mobile Station (MS), increasing in steps the TX power by as much as a basic unit amount and, determining whether an MS located outside a building has accessed the indoor BS using the received channel quality information in every increase and, when the MS located outside the building has accessed the indoor BS, decreasing the TX power of the indoor BS.
Claims40
A method for determining the Transmit power (TX power) of an indoor Base Station (BS) in a wireless communication system, the method comprising:
- receiving received channel quality information associated with the indoor BS from at least one Mobile Station (MS);
- increasing in steps the TX power by as much as a basic unit amount and determining whether at least one MS located outside a building has accessed the indoor BS using the received channel quality information in every increase;
- and
- when at least one MS located outside the building has accessed the indoor BS, decreasing the TX power of the indoor BS.
An operation method of a server managing an indoor Base Station (BS) in a wireless communication system, the method comprising:
- when a Transmit power (TX power) increase, decrease or maintenance request is received from the indoor BS, determining a permission or non-permission for the TX power increase, decrease or maintenance request in consideration of an average load of at least one indoor BS installed within a building where the indoor BS is located;
- and
- instructing the indoor BS about a TX power increase, decrease or maintenance.
An apparatus for determining the Transmit power (TX power) of an indoor Base Station (BS) in a wireless communication system, the apparatus comprising:
- a modem configured to receive received channel quality information associated with the indoor BS from at least one Mobile Station (MS);
- and
- a controller configured to increase in steps the TX power by as much as a basic unit amount and determine whether at least one MS located outside a building has accessed the indoor BS using the received channel quality information in every increase and, when at least one MS located outside the building has accessed the indoor BS, decrease the TX power of the indoor BS.
A server apparatus for managing an indoor Base Station (BS) in a wireless communication system, the apparatus comprising:
- a manager configured to store load information on at least one indoor BS;
- and
- a controller configured to, when a Transmit power (TX power) increase, decrease or maintenance request is received from the indoor BS, determine the permission or non-permission for the TX power increase, decrease or maintenance request in consideration of an average load of at least one indoor BS installed within a building where the indoor BS is located, and to instruct the indoor BS about a TX power increase, decrease or maintenance.
