    摘要: A method of transmitting a channel quality indicator (CQI) includes obtaining CQIs for each of a plurality of sub-bands, a sub-band comprising a plurality of sub-carriers, dividing the plurality of sub-bands into a plurality of layers according to a CQI of a sub-band, a layer comprising at least one sub-band, obtaining a representative value of a representative layer, the representative layer including a sub-band having maximum CQI and transmitting the representative value of the representative layer. Signaling overhead due to CQI feedback can be reduced.

    摘要: There is provided a method of allocating reference signals in a multiple-input multiple-output (MIMO) system. The method includes allocating a first reference signal, a second reference signal and a third reference signal in a first OFDM symbol so that the first reference signal, the second reference signal and the third reference signal do not overlap with each other and allocating the first reference signal, the second reference signal and a fourth reference signal in a second OFDM symbol so that the first reference signal, the second reference signal and the fourth reference signal do not overlap with each other. The first reference signal and the second signal are allocated in a regular intervals in a single OFDM symbol.
