A method for transmitting and receiving data in a cooperative Multiple-Input Multiple-Output (MIMO) mobile communication system is disclosed. The method includes selecting a transmission path for transmitting precoding-related feedback control information to one or more cooperative base stations operating in the cooperative MIMO mode, and transmitting the precoding-related feedback control information to the one or more cooperative base stations through the selected transmission path.

摘要:
A method for allocating fractional frequency reuse (FER) resources to perform cooperative MIMO in a multi-cell environment is disclosed. A cell which requests FER resources decides a band for cooperative MIMO with its neighboring cell, and requests the neighboring cell to allocate the decided band for cooperative MIMO. A cell which receives FER resource request receives a request from a neighboring cell to allocate some or all of FER bands allocated to the neighboring cell as a band for cooperative MIMO, decides whether to grant the request, and allocates some or all of the requested FER bands as the band for cooperative MIMO with the neighboring cell if the request is granted.

摘要:
The present invention relates a method for transmitting and receiving data in a mobile communication system. More specifically, the invention relates to a method through which a terminal in a cell boundary receives data in a mobile communication system that supports MIMO (Multi Input Multi Output). The method comprises: a step for receiving a first data stream transmitted through multiple transmission antennas from a serving base station, a step for pre-coding a second data stream to make the time delay of the second data stream be different from that of the first data stream and receiving the second data stream from a collaborating base station, and a step for restoring the data based on the first and second data streams.

摘要:
The present invention relates to a channel quality information transmission method in a communication system adopting a coordinated multi-point scheme. A terminal receives signals, through the same band, from a serving base station and at least one neighbor base station, respectively, which are included in a CoMP set operating in a joint processing mode. Next, the terminal generates combined channel quality information on a single signal obtained by combining the signals received through the same band, and then transmits the information to the serving base station. The combined channel quality information is generated using information on a combined channel obtained by combining channels between the terminal and the serving base station and between the terminal and each one of the at least one neighbor base station, which are included in the CoMP set.
