Abstract
An apparatus and method of determining a modification of a wireless service use for spectrum liberalization is provided. When a licensee using a wireless service in a particular band desires to modify the wireless service use, the method of determining a modification of a wireless service use for spectrum liberalization may determine whether to modify the wireless service use through a worst-case interference check scheme and a Monte-Carlo interference check scheme.
Claims15
A method of determining a modification of a wireless service use for spectrum liberalization, the method comprising:
- setting an input parameter of each of an interfered receiver, an interfering transmitter, an opposing transmitter, and a target receiver;
- computing a first interference signal strength, received from the interfering transmitter by the interfered receiver, using the input parameter and a worst-case interference check scheme;
- comparing the first interference signal strength with an admissible interference threshold value;
- computing a second interference signal strength, received from the interfering transmitter by the interfered receiver, using a Monte-Carlo interference check scheme, when the first interference signal strength is greater than the admissible interference threshold value;
- comparing the second interference signal strength with the admissible interference threshold value;
- and
- determining the modification of the wireless service use depending on a result of the comparison.
An apparatus of determining a modification of a wireless service use for spectrum liberalization, the apparatus comprising:
- a setting unit to set an input parameter of each of an interfered receiver, an interfering transmitter, an opposing transmitter, and a target receiver;
- an interference signal strength computation unit to compute a first interference signal strength, received from the interfering transmitter by the interfered receiver, using the input parameter and a worst-case interference check scheme, or to compute a second interference signal strength, received from the interfering transmitter by the interfered receiver, using a Monte-Carlo interference check scheme;
- a comparison unit to compare the first interference signal strength or the second interference signal strength with an admissible interference threshold value;
- and
- a determination unit to determine the modification of the wireless service use depending on a result of the comparison.
