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 system and method for detecting discontinuous transmission (DTX) frames. The inventive method includes the steps of receiving data transmitted in a plurality of frames; classifying each of the frames; analyzing the classification of a number of successive frames of the received data and providing a metric with respect thereto; and determining, in response to the metric, if a frame is a discontinuous frame. In the illustrative embodiment, the step of classifying includes the step of error checking the frames using a cyclic redundancy check (CRC) error checking protocol. The received frames are classified as good frames (G), erasure frames (E), or discontinuous frames (D). A numerical value is assigned to each of the frames based on the classification thereof. Next, the frames are filtered to provide an output Yn=Yn−1+Xn where ‘n’ is a frame number, Yn is the filter output for a given frame n, Yn−1 is the filter output for a previous frame, and Xn is a stream of input frames. A threshold is set for the output Yn to facilitate the detection of discontinuous frames. That is, a detection of a discontinuous transmission frame is indicated when a frame is classified as an ‘erasure’ and the filter output exceeds the threshold. On the detection of a discontinuous frame, the classification of the frame is changed from ‘erasure’ to ‘discontinuous’. By reclassifying improperly classified erasure frames, the mobile receiver is inhibited from requesting retransmission of the frames or a change in the transmit power level. Consequently, network throughput and capacity are optimized and system power is conserved.

摘要： A method and apparatus for generating an autonomous Pilot Strength Measurement Message (PSMM) by a mobile station traveling in a multi-carrier wireless communication system. In a multi-carrier system, the mobile station receives the pilot channel of a base station on multiple carrier frequencies simultaneously. Fading may vary from carrier frequency to carrier frequency. New pilot strength definitions are used by the mobile station in a set of rules transmitted by the base station. The set of rules determines autonomous generation and transmission of PSMMs by the mobile station upon detection of pilots.

摘要： The present invention provides a method and apparatus for maximizing throughput of a data call in a wireless communication system in which data is transmitted from a wireless station, such as a mobile station, on multiple assigned channels in accordance with a known transmission standard, such as IS-95B. The multiple assigned channels include a fundamental channel and at least one supplemental channel. Data is formatted into variable rate data frames and transmitted on the fundamental channel and the supplemental channel. A wireless receiver, such as a base station, receives the multiple assigned channels. The wireless receiver demodulates and decodes data frames associated with each of the multiple assigned channels. The wireless receiver determines a likely initial data rate for each demodulated and decode data frame. The wireless receiver correlates all of the likely data rates, by comparison to one another and to a relevant transmission protocol standard, to determine a maximum likelihood combination of data rates. The maximum likelihood combination of data rates includes a maximum likelihood data rate corresponding to each likely data rate. Decoded data frames are invalidated and erased when the likely data frame rates do not match corresponding maximum likelihood data rates.

摘要： A system for facilitating the acquisition of a most desirable wireless service for a wireless phone. The system includes a scanning mechanism for periodically scanning for a signal indicative of a wireless service having a coverage area that overlaps one or more coverage areas of other wireless services. A service acquisition mechanism acquires the wireless service or one of the other wireless services based on predetermined selection criteria and the signal. More specifically, the present invention includes a wireless phone having a first mechanism for determining if a detected system, i.e., service is associated with a coverage area that overlaps one or more coverage areas of different systems. A second mechanism compares the different systems to the detected system and selects a preferred system based on the comparison. A third mechanism acquires the preferred system. In the specific embodiment, the wireless phone includes a computer that runs software for implementing the first, second, and third mechanisms.
