This invention proposes a novel common packet data channel (CPDC) system structure and method to efficiently provide variable-rate packet data services in CDMA system. This system uses common code channels to serve packet data calls for a plurality of packet data users within a cell or sector. On the forward link (base station-to-mobile), an ATM-type multiplexing scheme is employed on a common code channel, while a spread ALOHA-type random access scheme is used on the reverse link (mobile-to-base station). The overhead due to call setup and channel assignment in a conventional circuit-switched system is not required in this system. The delay due to the call setup is reduced. In addition, ATM cells can be directly transmitted over the air interface. Novel transceiver architectures for the terminal and base station for implementing a system as well as particular channel signal structures are disclosed.
