    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. 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. 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 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: 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.

    摘要: A method and apparatus for high rate CDMA wireless communication in which a set. of individually gain adjusted subscriber channels are formed via the use of a set of orthogonal subchannel codes (W i ) 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 (134) and sequence repeated before being modulated with one of the subchannel codes, gain adjusted (152, 154, 156, 158), and summed (160), with data modulated using the other subchannel codes. The resulting summed data is modulated using a user long code an pseudorandom spreading code (PN code) and upconverted for transmission.

    摘要: A novel and improved method for implementing a high-transmission-rate over-the-air interface is described. A transmit system provides an in-phase channel set (90) and a quadrature-phase channel set (92). The in-phase channel set (90) is used to provide a complete set of orthogonal medium rate control and traffic channels. The quadrature-phase channel (92) set is used to provide a high-rate supplemental channel and an extended set of medium rate channels that are orthogonal to each other and the original medium rate channels. The high-rate supplemental channel is generated over a set of medium rate channels using a short channel code. The medium rate channel are generated using a set of long channel codes.
