according to an embodiment of the present invention the ofdm subcarrier blocks may be divided into n subcarrier block sets sbs fig1 a shows the distribution of transmission power for subcarrier blocks according to a prior art system fig1 b shows three examples for the distribution of power limits or ranges with different sbs definitions according to different embodiments of the present invention the assignment of the power limits may be performed in accordance with the sbs power limits in adjacent cells in order to control the sir levels depending on the sbs as e g shown in fig5 compared to prior art this power limit definition has the advantage that the intercell interference variations on subcarrier block basis are reduced since the caused interference from a given adjacent cell cannot exceed a specific upper limit due to the sbs upper transmit power limit in prior art the transmit power per subcarrier block may have any value between zero and a defined maximum with the constraint that the total transmit power must not exceed the maximum allowed transmit power fig1 a shows such a subcarrier block power allocation for a power controlled system according to an embodiment of the present invention the subcarrier blocks may.
