A method for transmitting signal, at a mobile station, in a wireless communication system is provided. Inter-cell interference level control parameter information may be different for each frequency partition due to use of an FFR scheme. This method is advantageous in that, when uplink transmission is performed, system throughput and cell edge-user throughput are improved and inter-cell interference level control is efficiently performed, thereby improving a Signal to Interference plus Noise Ratio (SINR) at the receiving end.

The present invention relates to a wireless communication system, and more particularly, to a method for allocating a resource for multicast and/or broadcast service data in a wireless communication system and apparatus therefore. The present invention includes the steps of dividing a downlink frequency band into a plurality of frequency partitions, allocating one or more subbands in a certain frequency partition among the plurality of frequency partitions to the MBS data, and c) allocating one or more subbands in each remaining frequency partitions one by one to the MBS data, if the number of subbands required for transmitting the MBS data (KSB,E MBS) is larger than the number of subbands in the certain frequency partition.

A method and device for wirelessly communicating between a mobile communication terminal and a base station, including exchanging one or more resource units between the base station and the mobile communication terminal, each resource unit having 18 subcarriers by a plurality of Orthogonal Frequency Division Multiple Access (OFDMA) symbols. The one or more resource units are permutated using X contiguous subcarriers as a permutation unit in each OFDMA symbol, wherein X is a positive integer that is a multiple of 2 as well as a divisor of 18.
摘要:
A method and apparatus for controlling uplink transmit power in a wireless communication system are disclosed. The method includes determining an uplink transmit power for each of the plurality of transmission channels, and sequentially allocating the determined uplink transmit powers to the transmission channels in a descending order of predetermined priority levels of the transmission channels, within a maximum available transmit power of the user equipment. The priority levels of the transmission channels are predetermined so that control channels, a sounding channel, a data channel, and a bandwidth request channel have priority levels in a descending order.
