    摘要: Disclosed is a method and apparatus for transmitting data in a cellular communication system including at least one base station that communicates with a plurality of mobile stations through a given frequency band. The method and apparatus divides the frequency band into at least two subcarrier groups each including a plurality of subcarriers; allocates at least one subcarrier group to each mobile station, and changes the subcarrier group allocated to each mobile station according to a predetermined period; and codes data to be transmitted to each mobile station with a plurality of codes, and transmits modulation symbols obtained by performing inverse fast Fourier transform (IFFT) on a plurality of subcarriers of the allocated subcarrier group.

    摘要: Provided is a coordinated communication method and apparatus that may perform coordinated communication based on long-term channel information, for each sub-band. Base stations may exchange scheduling information of each sub-band with each other to determine a priority among the base stations, and may perform rescheduling for each sub-band based on the determined priority. The base stations may obtain the long-term channel information, and thus may reduce overhead occurring with exchanging of information between a base station and a terminal or between base stations, and may decrease damage due to a delay of channel information associated with a terminal.

    摘要: The invention relates to a multi-transmission/reception antenna device and a multi-transmission/reception method in a multi-user and multi-cell environment. When a plurality of spatial subchannels having a multi-user and a multi-transmission/reception antenna are allocated to users (that is, user terminals), a user group to be supported and the number of users are selected in consideration of an influence of interference signals from adjacent cells. Accordingly, variability and independence of channels for users and interference signals from adjacent cells can be effectively used, thereby improving a transfer rate of a wireless communication system. The invention allows data transfer at higher speed with limited wireless resources. In particular, an influence of interference from adjacent cells that is inevitable in a multi-cell environment primarily used for the efficient use of wireless resources can be removed using a multi-transmission/reception antenna, while a transfer rate of each user can be effectively increased.
