ABSTRACT:
Transmission methods for a paging indication channel in code division multiple access (CDMA) mobile communication system are provided, wherein signals are transmitted when paging indication bits indicate that user equipment has paging information, and when the user equipment has no paging information, the corresponding paging indication bits are set to 0, and the transmission of the signals are closed off. For example, it assumes that the number of the user equipment supported by a paging indication channel is 144, and the total bits are 288. If only one user equipment is paged at this time, it is required to transmit only two bits, and the signals of the other 286 bits will not be transmitted. Therefore, comparing to prior transmission methods for a paging indication channel, the methods in the present invention significantly reduce transmission power and interference and increase the capacity of the entire system.
