摘要： Methods and systems for estimating and canceling pilot interference in a wireless (e.g., CDMA) communication system. In one method, a received signal comprised of a number of signal instances, each including a pilot, is initially processed to provide data samples. Each signal instance's pilot interference may be estimated by despreading the data samples with a spreading sequence for the signal instance, channelizing the despread data to provide pilot symbols, filtering the pilot symbols to estimate the channel response of the signal instance, and multiplying the estimated channel response with the spreading sequence. The pilot interference estimates due to a plurality of interfering multipaths are accumulated to derive the total pilot interference, which is subtracted from the data samples to provide pilot-canceled data samples. These samples are then processed to derive demodulated data for each of at least one (desired) signal instance in the received signal.

摘要： In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.

摘要： Methods and apparatus used in a wireless communication system. A data request message may be periodically transmitting by a mobile station to a base station. The data request message may provide information about orthogonal codes to be used by the base station to communicate with the mobile station. The mobile station may receive data transmitted by the base station, the data being transmitted by the base station based on the information about the orthogonal codes provided in the data request message. The information about the orthogonal codes may be based on a quality measure made by the mobile station on a forward link pilot channel from the base station to the mobile station.

摘要： Reverse link busy bits are independently generated by each base station and indicate whether a base station has reached a reverse link capacity limit. A remote station combines multipath components of the reverse link busy bits in its Active Set and in response transmits a reverse link signal only when all of the reverse link busy bits indicate that the base stations in the Active Set have reverse link capacity. In an embodiment, the remote station weights the reverse link busy signals in accordance with the signal strength of the transmitting base station and determines whether to transmit based on the weighted sum of the busy signals. In an embodiment, the remote station weights the reverse link busy signals in accordance with the signal strength of the transmitting base station and determines a maximum reverse link data rate based on the weighted sum of the busy signals.
