摘要： Disclosed is a method for partitioning resource spaces, and allocating physical channels and power in an OFDMA-based cellular system. A resource within a slot is partitioned into resource spaces in common in a plurality of adjacent cells, and the partitioned resource spaces are partitioned into resource sets according to sizes of physical channels in the adjacent cells. The physical channels classified by predetermined characteristics are respectively assigned to the partitioned resource sets within the resource space. Further, the resource space for transmitting traffic channels between two different cells is partitioned into resource spaces so that the traffic channels in the same subspace may be collided with each other, and a power control is applied between the collided channels to control the interference from the adjacent cells.

摘要： A receiving apparatus of a UE transmits at least one channel information among a plurality of channel information to a transmitting apparatus of a base station according to an adaptive transmission method set for a received signal. In addition, the receiving apparatus transmits channel state information generated on the basis of the plurality of channel information to the transmitting apparatus with a relatively long interval. The transmitting apparatus transmits traffic data to the transmitting apparatus by using the received channel state information and at least one of channel information and one of a plurality of adaptive transmission methods. Accordingly, the amount of channel information transmitted to the transmitting apparatus can be modified in accordance with an adaptive transmission method set for a received signal, thereby minimizing the amount of channel information fed back from the receiving apparatus and increasing system capacity.

Fine symbol synchronization, fine frequency synchronization, and downlink frame synchronization is estimated by using an estimated cell search result. Downlink frequency and time tracking is performed, cell tracking is performed by using a position set of pilot subcarriers inserted into the downlink frame, fine symbol synchronization tracking and fine frequency synchronization tracking are repeated by using the pilot subcarriers to perform the frequency and time tracking of the downlink frame.
