Abstract:
1. A bit calculation apparatus, comprising: a resource allocation unit allocating a resource, on a downlink data channel; a channel analysis unit analyzing channel use circumstances to check a usable resource, on the resource required by the resource allocation unit; a subcarrier analysis unit checking a plurality of usable subcarriers, on the usable resource; and a bit calculation unit calculating the number of transmission bits per codeword transmitted through the downlink data channel according to the usable subcarriers and a modulation type of a modulator, wherein the subcarrier analysis unit comprises: a subcarrier calculator; and a subcarrier compiler, wherein the subcarrier calculator calculates the number of the usable subcarriers of a usable resource block per Orthogonal Frequency Division Multiplexing (OFDM) symbol by antenna set, and the subcarrier compiler compiles the number of the usable subcarriers of the resource block.
