Abstract:
1. A method of fractional frequency reuse for assigning physical resource units of a contiguous frequency band to sectors of cells, each cell including at least one base station, for transmission of data to users in the sectors, the method comprising: for each cell, segmenting the frequency band such that each separate segment includes a first contiguous portion of physical resource units dedicated to all sectors of the cell in vicinities of the center of the cell and a second contiguous portion of physical resource units dedicated for use in only one of the sectors in the cell in an outer area of the cell; assigning each cell with a physical resource unit configuration such that the second contiguous portion of physical resource units of a sector of a given cell partially overlaps with the first contiguous portion of physical resource units in a segment including the second contiguous portion dedicated to the same sector of a cell neighboring the given cell; and transmitting the data to the users in the sectors in accordance with the assigned physical resource unit configurations.
