BAND-EFFICIENT METHOD AND SYSTEM FOR TRANSMITTING/RECEIVING A COMMUNICATION SIGNAL USING A CHANNEL BAND |
| 摘要 |
<p>A method for transmitting a further signal on a channel having a transmission band including a plurality of used subbands occupied by transmission signals. According to the method, the presence of free subbands not occupied by the transmission signals is detected and the further signal is transmitted using the free subbands. According to the method, the further signal is multiplexed by using a CDMA code and transmitted on OFDM subcarriers having frequencies within the free subbands.</p> |
