초록 ▼

A Code Division Multiple Access (CDMA) communication system which contains a calling channel which is used to inform silent mobiles that they are being called. In the system, the calling channel is chosen to be the strongest overlapping signal so that it reaches mobiles which are located on the cells extreme boundaries. The interference other signals experience because they overlap with the calling channel may be avoided by having the mobiles first demodulate the calling channel signal and then subtract it out before demodulating their own signal.

대표청구항 ▼

An apparatus for transmitting control information and user traffic signals from a first base station to a plurality of mobile stations in a code division multiple access communication system, comprising: first coding means for coding control information using a spread spectrum code unique to control information to form a calling channel signal; a second coding means for coding each user traffic signal using a spread spectrum code unique to each traffic signal; summation means for adding said calling channel signal and said coded traffic signal using predetermined weighting factors to obtain a composite signal; modulation means for modulating said composite signal on a radio frequency carrier to form a radio frequency signal; transmitting means for transmitting said radio frequency signal to said plurality of said mobile stations; receiving means for receiving said radio frequency signal at at least one of said mobile stations; decoding means for decoding said received signal at said mobile station to extract said control information, wherein said control information is used by said mobile station to determine if said mobile station is being called and to determine a phase of the calling channel signal; and second decoding means for decoding said radio frequency signal in said mobile station using said phase of the calling channel signal to extract traffic information intended for said mobile station.
