    • This concurrent packet data session set-up for Push-to-talk over Cellular (PoC) services decreases the connection set-up time for a PoC call by using processes that are circuit-switched-based to locate and page a called communication device, and to initiate traffic and packet data session set-ups for the called communication device. A method for setting up a packet data session between an originating communication device (211) and a called communication device (215) includes the steps of: requesting a called-device active packet data session set-up for the called communication device (messages 271, 272, 273, 274, 275) and initiating an originating-device active packet data session set-up for the originating communication device (messages 271, 222, 224). The first step can use circuit-switched-based messages and processes to locate the called communication device and set up a traffic channel for the called communication device. After an active packet data session (263) is set-up for the originating communication device (211), the originating-device active packet data session (263) can be used to request a PoC voice channel (message 290). Because a called-device active packet data session set-up has already been requested, the called communication device (215) can respond to the PoC voice channel request quickly (message 293).

    • A CDMA communication system supports underlay transmissions and direct spread overlay transmissions such that the overlay transmissions are at least partially orthogonal to underlay transmissions. A base station supports both the underlay transmissions and the overlay transmissions and includes an interface to a mobile switching center, an underlay unit, an overlay unit and at least one radio frequency (RF) unit. The interface receives communications intended for a plurality of mobile stations serviced by the base station. These communications include underlay communications intended for mobile stations (MSs) supporting underlay transmissions and overlay communications intended for MSs supporting overlay transmissions. The underlay unit receives the underlay portion of the communications and produces underlay transmissions. The overlay unit receives the overlay portion of the communications and produces overlay transmissions. Then, the underlay transmissions and the overlay transmissions are received by the at least one RF unit and transmitted via at least one antenna to the plurality of MSs. Each of the MSs receives both the underlay transmissions and the overlay transmissions. However, those MSs supporting the underlay transmissions extract intended underlay communications while the MSs supporting overlay transmissions extract intended overlay communications. The underlay unit and the overlay unit produce the overlay transmissions such that they are at least partially orthogonal to the underlay transmissions. A synchronization unit coupled to the underlay unit and the overlay unit that causes the overlay transmissions to be substantially synchronized with the underlay transmissions. In another construction, differing base stations provide the underlay transmissions and the overlay transmissions.

    • In a receiver of a simulcast multi-carrier CDMA (code division multiple access) communications system, a combined data signal is produced by combining signals representing data received for the plurality of carriers and is multiplied by the complex conjugate of a composite reference signal, representing characteristics of the plurality of carriers, produced by combining signals representing a reference signal received for the plurality of carriers, thereby improving multi-path resolution due to frequency diversity of the reference signal over the multiple carriers of the system. The receiver can be simplified by demodulating the signals of the plurality of carriers in common to produce a demodulated signal which is common to the data and reference signals for the plurality of carriers, the data and reference signals being subsequently separated using their respective orthogonal codes. Data signals can be recovered both with and without the improved multi-path resolution over the multiple carriers, and an optimum selection between them can be made.
