Method and transceiver apparatus for transmitting paging information in orthogonal frequency-division multiplexing systems
The present invention provides a method for transmitting paging information in orthogonal frequency-division multiplexing (OFDM) systems as well as the transmitter and receiver apparatus for its application. The method features itself in the following aspects: An auxiliary paging channel is employed dedicatedly for spread-spectrum modulation or digital modulation of the paging information. When the receiver is in a standby state, paging information can be obtained by means of spread spectrum demodulation or digital demodulation with no need to conduct FFT. This leads to a great reduction in power consumption and less power is consumed when the receive devices are in standby state, hence achieving aim to lengthen the usable time of a battery in a mobile phone.
