ABSTRACT:
A method and system are provided for increasing channel usage efficiency of data transmissions in a code division multiple access (CDMA) communication system by assigning more than one user wireless communication device to a single data channel. A base station is arranged to communicate CDMA data signals with a plurality of wireless communication devices in the form of data packets. A wireless communication device generates a request for assignment of an identification key code as part of a call initiation process. The base station then assigns an identification key code to the requesting wireless communication device which is transmitted in a header of each data packet. The base station also sets a level of transmission power for the wireless communication devices as a function of the number of wireless communication devices assigned to the data channel and the available bandwidth of the channel. Either a unique key code can be assigned, or a common key code allowing a selected grouping of users to receive broadcast data packets. The present invention is also applicable to the reverse link.
