摘要： A dynamic shared forward link channel (or “data” channel) is used to send multicast data to a group of wireless devices, e.g., using a common long code mask for the data channel. Reference power control (PC) bits are also sent on the data channel and used for signal quality estimation. A shared forward link control channel is used to send user-specific signaling to individual wireless devices, e.g., using time division multiplexing (TDM) and a unique long code mask for each wireless device. A shared forward link indicator channel is used to send reverse link (RL) PC bits to the wireless devices, e.g., using TDM. The data channel is jointly power controlled by all wireless devices receiving the data channel. The control and indicator channels are individually power controlled by each wireless device such that the signaling and RL PC bits sent on these channels for the wireless device are reliably received.

摘要： A novel and improved method for performing paging is described. In one embodiment of the invention a searcher is used to detect spread spectrum signals. Samples received RF signals are stored in a sample buffer. During standby mode, the samples are gathered during paging slots assigned to the mobile. A set of searches are performed on the samples, and if pilot signals are detected additional demodulation is performed to detect paging messages. The resulting set of demodulation data may be combined to increase detection. After a page message has been detected, additional demodulation resources may be activated to processes more complete page messages, or other information channels. In one embodiment of the invention, the searcher includes a demodulator to perform quick page detection without the use of finger elements to reduce idle mode power consumption.

摘要： A composite signal has two components, each carrying a stream of information that may be digital. In one application of a method according to an embodiment of the invention, at least one of the components is delayed such that a time relation between the streams of information is altered. The components are transferred via a common signal path such that upon transfer, the original time relation between the streams of information may be restored.

摘要： A spreading system according to an embodiment of the invention spreads two data signals. The system produces a filtered signal that is based on one of the data signals and an output signal that is based on both of the data signals. In one example, a spreading system is used to perform QPSK spreading of two data signals, including separate processing of the two data signals, in a practical manner. Such separate control may include filtering and/or gain control.
