Abstract
A first sector cell is set as an object for measurement (S ). Reception levels in each time slot in the number of TDMA-TDD frames is measured for the object cell (S ) and for all the cells (S and S ). The results of the measurement of a specific sector cell are added to the results of the measurement of a sector cell opposite the specific sector cell, and time slots in which control channels can be placed are extracted for each sector cell (S to S ). TDMA-TDD frames are then allocated such that the control channels of each sector cell coincide with time slots in which control channels can be placed (S ). In this way, control channels are placed in time slots such that a base station having a sector cell structure avoids interference from the same frequency.
