A method of determining a serving sub-cell of a terminal among a plurality of sub-cells by a base station in a wireless communication system is provided. The method includes generating reference signal transmission interval information for each of the sub-cells by configuring a reference signal transmission interval for each of the plurality of sub-cells, and transmitting the reference signal transmission interval information for each of the sub-cells to the corresponding sub-cell, receiving channel status information for at least one sub-cell among the plurality of sub-cells from the terminal, and determining a serving sub-cell of the terminal by using at least one of the reference signal transmission interval information, the channel status information, a reception time of the channel status information, of each of the sub-cells.

A method and apparatus for selecting a retransmission mode in a MIMO communication system are provided wherein a receiver receives m initial transmission streams from a transmitter, m being an integer of 2 or larger, channel-decodes the m initial transmission streams and checking errors in the m channel-decoded streams, selects, if at least two channel-decoded streams have errors among the m channel-decoded streams, a retransmission mode to be used for the at least two streams having errors in the transmitter, and transmits information including the selected retransmission mode to the transmitter.
