    摘要: A method and apparatus provides for efficient data rate control and power control processes by transmitting a primary and a secondary pilot channel associated with a data channel in the reverse (uplink) link. The primary and secondary pilot channels are used for decoding the data. A ratio of power levels of the primary and secondary pilot channels is based on at least one of the data rate and payload size of the data channel. It is determined whether the transmission of the primary pilot channel and the secondary pilot channel associated with the data channel is necessary based on comparing one of the data rate and the payload size of the channel in the reverse link to a predetermined value. The power level of the primary pilot channel is maintained independent of at least one of data rate and payload size of the data channel. The power level of the secondary pilot channel may be adjusted based on at least one of data rate and payload size of the data channel.

    摘要: A novel and improved method for performing transmit power control on a reverse link is described. A signal is transmitted at a transmit power and includes a traffic channel transmitted at a traffic channel transmit power, and a pilot channel transmitting at a pilot channel (70) transmit power. The receive energy of the pilot channel is measured, and a decrease power control command (121) is generated when the receive energy is greater than receive energy threshold. If the receive energy is less than the receive energy threshold, an increase power control command (121) is generated. The power control command (121) is transmitted to the system generating the signal.

    摘要: A method and apparatus for minimizing disruption during a frequency search excursion to a target frequency. The method may be preformed as part of inter-frequency hard-handoff between cells on different RF CDMA channels. The method minimizes search times by tuning a selected mobile station (102) to a target frequency and collecting chip samples which are then stored in a buffer (207). Pilot searches and pilot strength measurements are not performed while on the target frequency. The selected mobile station (102) is tuned back to the original frequency and simultaneously resumes reception of forward link and transmission of reverse link communications. The chip samples collected on the target frequency are processed to calculate pilot strength. In another embodiment, the method minimizes disruption of service on the current frequency during the frequency search by increasing the amount of power allocated to other symbols contained in a data frame impacted by the search excursion. This power increase is a function of search excursion time.

    摘要: A set of individually gain adjusted subscriber channels (A, B, C, Pilot) are formed via the use of a set of orthogonal subchannel codes (Walsh+-, Walsh++--) having a small number of PN spreading chips per orthogonal waveform period. Data to be transmitted via one of the transmit channels is low code rate error correction encoded and sequence repeated before being modulated with one of the subchannel codes, gain adjusted, and summed with data modulated using the other subchannel codes. The resulting summed data (316) is modulated using a user long code and a pseudorandom spreading code (PN code) and upconverted for transmission. The use of the short orthogonal codes provides interference suppression while still allowing extensive error correction coding and repetition for time diversity to overcome the Raleigh fading commonly experienced in terrestrial wireless systems. The set of sub-channel code may comprise four Walsh codes, each orthogonal to the remaining codes of the set. The use of four sub-channels is preferred as it allows shorter orthogonal codes to be used, however, the use of a greater number of channels and therefore longer codes is acceptable. Preferably, the pilot data and control data are combined onto one channel. The remaining two transmit channels are used for transmitting non-specified digital data including user data or signaling data, or both.

    摘要: The invention relates to a method and apparatus for data transmission comprising the steps of encoding a first set of data symbols to provide a first set of encoded symbols and a second set of encoded symbols; transmitting the first set of encoded symbols in a first frame; encoding a second set of data symbols to provide a third set of encoded symbols; determining whether the first frame failed to decode; determining a minimum retransmission power level for the second set of encoded symbols if the first frame failed to decode; and transmitting the second set of encoded symbols and the third set of encoded symbols in a second frame if the first frame failed to decode. Efficient transmission of data is achieved by determining a minimum retransmission power level in the event transmitted encoded symbols fail to decode.
