Abstract: A method for transmitting buffer size information is provided to prevent a difference between an actual buffer size and a coded buffer size from increasing as using a small number of bits even when a buffer size increases. A mobile station transmits a buffer status report to a base station. The buffer status report includes plural resource blocks. One resource block includes a resource block identifier and a buffer size field. The buffer size field includes information about a size of a buffer. By first and second bit streams(210,220), the buffer size information of a communication device is coded. If a buffer size of the communication device is bigger than or equal to a first predetermined value, a bit stream including the first and second bit streams is transmitted. The first bit stream indicates a quotient generated by dividing the buffer size by a second predetermined value. The second bit stream indicates a value corresponding to the rest generated by dividing the buffer size by the second value.

Abstract: An antenna selection method in an orthogonalized spatial multiplexing system is provided to introduce real-number expressions for a complex number MIMO(Multi Input Multi Output) system to simplify MLD(Maximum Likelihood Decoding), thereby offering a single-symbol decoding spatial multiplexing method based on phase feedback. Two input symbols are pre-coded by a predetermined function according to previously fed-back channel state information. The pre-coded symbols are transmitted by being switched to two optimum transmission antennas among plural transmission antennas by using the channel state information. The transmitted symbols are received through plural reception antennas to decode the received symbols individually. New channel state information is fed back by selecting an optimum subset of the transmission antennas and determining a rotational angle on the basis of Euclidean distance between vectors of the decoded symbols.
