摘要 |
An OFDM-based multiple access method and a communication device controlling the same are provided. The OFDM-based multiple access method includes transmitting a predetermined synchronization control signal to many and unspecified terminals, and receiving a test message from the terminals in response to the synchronization control signal; classifying the terminals that receive the test message in a first unit time from a predetermined reference time after the transmission of the synchronization control signal into a first group, and classifying the terminals that receive the test message in a certain n-th unit time from the reference time into an n-th group; allocating use permission time of sub-channels to the groups; and the terminals transmitting/receiving data through partial occupation of the sub-channels and symbols at a time allocated to the corresponding groups.
