| titleOfInvention | Bandwidth Asymmetric Communication System |
| abstract | The present invention relates to a communication system, comprising: a plurality of terminals each having an uplink transmission unit (1) for transmitting radio frequency OFDM signals at a radio frequency and the radio frequency OFDM signals from at least two terminals; An access point having an uplink receiving unit 4 for simultaneous reception, wherein the OFDM signal is orthogonal frequency division multiplexed (OFDM) modulated, wherein the bandwidth of the uplink transmission unit and the transmitted radio frequency OFDM signals is: Less than the bandwidth of the uplink receiving unit, the bandwidth of at least two uplink transmission units and their transmitted radio frequency OFDM signals are different.n n n The invention also has a downlink transmission unit 7 for the access point to transmit radio frequency OFDM signals at radio frequency, each of the at least two terminals having a downlink reception unit 11 for receiving the radio frequency OFDM signals Wherein the bandwidth of the downlink transmitting unit is greater than the bandwidth of the downlink receiving units, the downlink transmitting unit is equal to or less than the bandwidth of the downlink transmitting unit and has a bandwidth equal to that of the downlink receiving unit. And a communication system adapted to generate and transmit, wherein radio frequency OFDM signals are received via the downlink receiving unit.n n n The invention further relates to a communication method, a terminal and an access point for use in such a communication system. |
