ABSTRACT:
A first data symbol that includes a kthdata bit is received over a multicarrier system. A first channel quality parameter is estimated for the first data symbol. A second data symbol that includes a retransmitted kthdata bit is received. A second channel quality parameter for the second data symbol is estimated. A probable value of the kthdata bit is determined based on both the first channel quality parameter and the second channel quality parameter. In response to an ARQ for data symbols communicated over a multicarrier system, the following are performed: determining channel quality parameters, each of the channel quality parameters corresponding to at least one of the transmitted data symbols; selecting a subset of the channel quality parameters exhibiting a worst quality; constructing a block of data symbols corresponding to the subset; and communicating the block of data symbols over a plurality of subcarriers.
