Abstract
A communication station includes a modulation circuit, a mapping circuit and a transmitting circuit. The modulation circuit is configured to operably modulate the master information block (MIB). The mapping circuit is configured to operably map the modulated MIBs to the new carrier type physical broadcast channel (PBCH). The PBCH is configured in a plurality of radio frames. The transmitting circuit is configured to operably transmit the radio frames. Moreover, the mapping circuit maps the modulated MIBs to only part of six central radio blocks of the predetermined subframes of the radio frames. The six central radio blocks are configured to locate around the DC subcarrier.
