A method for maintaining system interference at a low level when two or more users use one resource region in a wireless mobile communication system is provided. To control an uplink transmission power in a broadband wireless mobile communication system in multi-cell environments, information regarding the number of users who share an uplink time-frequency resource region is received from a base station, a power adjustment value is calculated based on the received number of users, and the uplink transmission power is determined by reflecting the calculated power adjustment value in a reference transmission power. Here, when only one mobile station uses the uplink time-frequency resource region, the reference transmission power is equal to a transmission power of the mobile station.

A method of transmitting data in a wireless communication system includes preparing a frame including a unicast subframe for unicast data and an MBS (Multicast and Broadcast Service) subframe for MBS data; and transmitting the unicast data and the MBS data via the frame, wherein the MBS subframe includes an idle time during which data is not carried, and the idle time is arranged to be at the temporally latest position in the MBS subframe. An MBS frame structure for using an appropriate CP with respect to MBS signals transmitted from multi-cell is provided, so an unnecessary idle time can be reduced, and thus, the efficiency of limited radio resources can be improved.

An adaptive resource partitioning method includes: selecting a predefined pattern-based partitioning method or an informed map-based partitioning method according to the number of channels used for resource allocation, data characteristics, and a channel environment variation, if the predefined pattern scheme is selected, selecting any of predefined patterns, partitioning distributed and localized resource allocation areas according to the selected pattern, and transmitting a pattern index of the selected pattern to a terminal, and if the informed map scheme is selected, partitioning distributed and localized resource allocation areas according to an arbitrary pattern, and transmitting bitmap control information indicating information of the partitioned areas to the terminal. So, it effectively obtains a diversity and a scheduling gain when distributed and localized resource allocations are simultaneously used, such that it increases flexibility of resource allocation, increases an available data transfer rate, and reduces an amount of necessary control information.

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 certain frequency band into a plurality of subbands, and allocating at least one subband to the MBS data from a subband having a lowest index among the plurality of subbands, wherein the MBS data is multiplexed with unicast data.

A method for transmitting signal, at a mobile station, in a wireless communication system is provided. Inter-cell interference information may be different for each frequency partition according to using a FFR scheme. Also, a parameter for controlling interference level between base stations may be different for each frequency partition. The present invention 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.

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 for setting uplink transmission power at a mobile station in a wireless communication system comprises the steps of: receiving information on the number of total streams received at a base station; and setting the uplink transmission power using the received number of total streams. In this case, the uplink transmission power is preferably a transmission power per stream (PTx—stream) obtained by applying the number of total streams to reference transmission power (PTx—ref).
