Abstract
An apparatus and method for allocating a frequency band to an MS in a cellular system with a frequency reuse factor of N are provided, in which a frequency allocator determines whether the MS receives data simultaneously from two BSs using neighboring FAs and allocates a frequency band to the MS according to the determination, and a subcarrier mapper maps the data to subcarriers according to the frequency band allocated to the MS.
Claims20
An apparatus of a Base Station (BS) for allocating a frequency band in a cellular system with a frequency reuse factor of N, comprising:
- a frequency allocator for determining whether a Mobile Station (MS) to which data is to be transmitted is able to receive data simultaneously from the BS using a first Frequency Assignment (FA) and a BS using a second FA neighboring to the first FA and allocating a frequency band to the MS according to the determination;
- and
- a subcarrier mapper for mapping the data to subcarriers according to the frequency band allocated to the MS.
A method of a Base Station (BS) for allocating a frequency band in a cellular system with a frequency reuse factor of N, comprising:
- determining whether a Mobile Station (MS) to which data is to be transmitted is able to receive data simultaneously from the BS using a first Frequency Assignment (FA) and a BS using a second FA neighboring to the first FA;
- checking the direction of the second FA with respect to the first FA, if the MS receives data simultaneously from the BSs using the neighboring first and second FAs;
- and
- allocating part of the first FA to the MS according to the direction of the second FA with respect to the first FA.
A Base Station (BS) for allocating a frequency band in a cellular system, comprising:
- a frequency allocator for determining whether a Mobile Station (MS) to which data is to be transmitted is performing a band sliding and allocating a frequency band to the MS according to the determination;
- and
- a subcarrier mapper for mapping the data to subcarriers according to the frequency band allocated to the MS.
