A method of transmitting packet data in a CDM and TDM mobile data communication system is provided. The method comprises determining priorities of one or more control channels, transmitting control information related to one or more packet data sets to one or more mobile stations through corresponding control channels according to the priorities; and transmitting the one or more packet data sets to each mobile station through one or more data channels that correspond to the one or more control channels, respectively. And, a frame duration of the higher priority data control channel restricts a frame duration of the lower priority data control channel.

What is claimed is: 1. A method of communicating packet data in a communication network, the method comprising the steps of: receiving information from a base station, the information including priorities of at least one control channel, control channel information, and a CDM indicator, the CDM indicator indicating whether CDM is currently being used or not; monitoring the at least one control channel according to the information received from the base station; and receiving a corresponding packet data set by each mobile station by using results obtained from the monitoring. 2. The method of claim 1, wherein the control channel information includes a maximum number of control channels and a number of control channels currently being used. 3. The method of claim 2, wherein each mobile station monitors the control channels according the maximum number of control channels, if the CDM indicator is not received and the maximum number of control channels is known. 4. The method of claim 1, wherein each mobile station monitors the control channels according to the CDM indicator, if the CDM indicator is received. 5. A method of transmitting packet data and control information between a base station and a mobile station in a radio communication system, the method comprising: transmitting first control information on a first packet data control channel; and transmitting second control information on a second packet data control channel, the first control information associated with a first packet data channel and the second control information associated with a second packet data channel; wherein the first and second packet data control channels are monitored by a mobile station in a predetermined order based on whether code division multiplexing (CDM) is used; wherein, if both the first and second control information is to be used, the first and second packet data control channels are to be decoded in a predetermined order such that the first control information is used before the second control information. 6. The method of claim 5, wherein the predetermined order is based on a number of packet data control channels being used. 7. The method of claim 5, further comprising transmitting additional information to at least one mobile station prior to transmitting packet data and transmitting the first and second control information, the additional information comprising at least one of information indicating whether CDM is supported, information indicating a maximum number of packet data channels, and information indicating whether CDM is currently being used. 8. The method of claim 5, further comprising transmitting Walsh code information to at least one mobile station, the Walsh code information corresponding to at least one of the first and second packet data control channels. 9. The method of claim 5, further comprising: scheduling packet data for transmission on at least one packet data channel; and transmitting the packet data through at least one packet data channel during at least one data transmission period. 10. The method of claim 5, further comprising transmitting information to indicate a maximum number of packet data control channels or a maximum number of packet data channels being supported. 11. The method of claim 5, wherein the first packet data channel and the first packet data control channel have a one-to-one correspondence and the second packet data channel and the second packet data control channel have a one-to-one correspondence such that each packet data control channel contains the control information for its associated packet data channel.
