Abstract:
1. A method of transmitting pilot signals in a mobile communication system, comprising: time-division multiplexing a first pilot signal and a second pilot signal for channel compensation together with a data signal of a user, which data signal is assigned a certain bandwidth and to be wirelessly transmitted, into a time-division multiplexed signal; frequency-division multiplexing the time-division multiplexed signal together with time-division multiplexed signals of other users into a frequency-division multiplexed signal; and transmitting the frequency-division multiplexed signal; wherein the first pilot signal is assigned a bandwidth larger than the bandwidth assigned to the data signal and the second pilot signal is assigned a bandwidth smaller than the bandwidth assigned to the data signal; and the first pilot signal and the second pilot signal are multiplexed along a time axis.
