摘要： A wireless communication system is provided that includes a plurality of origination stations and at least one terminal. The plurality of origination stations each communicate a signal comprising a regular page message over respective regular paging channels and a quick paging channel page message over respective quick paging channels. The terminal, when in an idle state during which an RF receiver is off, simultaneously monitors each of the quick paging channels for their respective quick paging channel page messages.

摘要： In order to align the timing of an overlay base station to the timing of an existing base station, a sync unit is introduced into the system. The sync unit has a first receiver configured to receive a first signal, the first signal having a first CDMA channelization. The first receiver is configured to produce an indication of a timing of the first signal. The sync unit also has a second receiver configured to receive a second signal, the second signal having a second CDMA channelization. The second receiver is configured to produce an indication of a timing of the second signal. The sync unit also has a time error detection unit configured to compare the timing of the first signal and the timing of the second signal to determine a relative timing offset thereof.

摘要： A method and apparatus for controlling transmission power levels in a mobile communication system. The method provides for a closed-loop power control method. A mobile station provides information on the quality of the signal received from the base station, and the base station responds by adjusting the power allocated to that user in a shared base station signal. The transmission power is adjusted initially by a large increment and then ramped down at an increasingly decreasing rate. The mobile station also provides information to the base station as to its relative velocity and the base station adjusts its transmission power in accordance with this velocity information.

摘要： A method and apparatus for providing diversity transmissions to a mobile unit from a transmitting station having at least first and second antennas by repeatedly switching between the two antennas during the transmission of information to the receiving unit. Message information is transmitted from the first antenna in the transmitting station to the receiving unit. After the start of the transmission of the message information from the first antenna, transmission of the message information from the first antenna to the receiving unit terminates and transmission of the message information from the second antenna in the transmitting station to the receiving unit is initiated. Some time after transmission of the message information from second antenna is initiated, the transmission of the message information from the second antenna to the receiving unit terminates and transmission of the message information from the first antenna in the transmitting station to the receiving unit is initiated. Repeated switching between the first and second antennas is achieved by repeating the process. The switching results in diversity transmissions that improve the ability of a receiving unit to receive the coded and interleaved transmitted message information from the transmitting station. The interleaver disperses the encoded symbols in each antenna dwell period such that the decoder decisions are based on a mix of symbols form each antenna. Therefore the decoder decisions are unreliable only when the mix of symbols from the different antennas, with different fading characteristics, are unreliable over the span of symbols the decoder uses in its decision process.

摘要： A forward link power control mechanism measures the reverse link power control bits which are transmitted on the forward traffic channel. At the remote station, the reverse link power control bits from multiples base stations or multiple signal paths are measured, combined, and filtered to yield an improved measurement of the forward link signal quality. The reverse link power control bits which are deemed unreliable are omitted from use in the power control loop. The remote station generates a set of forward link power control bit in accordance with the measurements and transmits these bits to all base stations in communication with the remote station. Each base station adjusts its gain of the forward traffic channel in accordance to its measurement of the forward link power control bit.

摘要： A method and apparatus which permits handoffs while the mobile station is in the system access state. This is achieved by providing for channel assignment messages to be sent over the paging channel of a plurality of base stations, which increases the probability of one of the messages getting through. In addition, this assures the mobile station will be able handoff to a different base station and have a traffic channel allocated to it on the new base station without delay. In addition, a method and apparatus which permits the mobile station to be directly assigned into a soft handoff state upon traffic channel assignment.

摘要： Techniques to enable the processing of multiple calls in a spread spectrum communications system. The call processing state machines defined by the CDMA standards (e.g., IS-95 and IS-2000) are modified to include a “traffic channel” substate indicative of the mobile station processing at least one active call. Call control (CC) state machines of various types are also provided to control the processing of the calls. To process one or more calls concurrently, a CC state machine is instantiated upon receiving an indication to process a particular call. The instantiated CC state machine is identified with, and used to control the processing of, the particular call. Upon receiving an indication to process an additional call, another CC state machine can be instantiated for the additional call. Correspondingly, upon receiving a directive to release a call, the call and its instantiated CC state machine are released. Each call to be processed can also be associated with a particular a service option connection, which includes information indicative of a set of parameters (e.g., the physical channels) to be used for data transmission.

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.
