摘要： A method is taught for improving the transmission of information signals in a communications system having a base station and a remote station. First and second transmission links are established with the remote station. An information signal is encoded to provide an encoded information signal having more bits than the information signal. First and second transmission signals are provided wherein each transmission signal has bits selected from the encoded information signal. Each of the first and second transmission signals is transmitted to the remote station by way of a respective one of the first and second transmission links. The remote station receives and combines the first and second transmission signals transmitted by the remote station to provide a combined encoded signal. The combined encoded signal is decoded by the remote station to provide the information signal. The first and second transmission links can be formed between the remote station and a single base station or between the remote station and two separate base stations.

摘要： Multipath RAKE receiver structure that allows for the concurrent demodulation of multipath signals that arrive at the receiver at arbitrarily low arrival time differences. The fingers are set to be a fixed offset from one another. One finger tracks the shift in the peak of the multipath component and the additional fixed offset fingers follow the tracking.

摘要： A method for wireless communications where a control packet is not transmitted for all transmissions of a new data packet. A control packet is only sent with a retransmission of a data packet where the previously transmitted data packet is not completely received. The control packet contains information related to a previously transmitted data packet. The previously transmitted data packet and the retransmission data packet are derived from common data. The common data is derived based on the information related to the previously transmitted data packet, wherein the previously transmitted data packet and the retransmission data packet are associated with a series of data packets.

摘要： Techniques to reduce transmit power required for transmission of messages from an access terminal to reduce interference to transmissions from other access terminals. In one aspect, messages to be transmitted are defined and/or coded such that they may be detected at different received signal qualities. The codewords may be defined having different distances to their nearest codewords. In another aspect, messages to be transmitted are assigned to different points in a signal constellation, with the points being located such that they may be received at different signal qualities. Codewords that may be received at a lower signal quality may be assigned to messages more likely to be transmitted at higher transmit power levels (e.g., when the access terminal is located further away) or to more frequently transmitted messages.

摘要： Methods and apparatus are presented for improving the feedback of channel information to a serving base station, which allows a reduction in the reverse link load while allowing the base station to improve the forward link data throughput. Over a channel quality indicator channel, three subchannels are generated; the re-synch subchannel, the differential feedback subchannel, and the transition indicator subchannel. The information carried on each subchannel can be used separately or together by a base station to selectively update internal registers storing channel conditions. The channel conditions are used to determine transmission formats, power levels, and data rates of forward link transmissions.

摘要： An efficient use of communication resources is provided by determining a behavior for selecting the payload size (data rate) of a reverse link transmission from a mobile station to a base station. The mobile station may store a predetermined table including the ratio of the power levels of the traffic channel and pilot channel (TPR), where each entry corresponds to one or more specific sizes of data payload, and consequently a data rate for transmission in a predetermined time frame. The payload size is selected based on an authorized-TPR. The authorized-TPR and a target-TPR are adjusted in accordance with a value of common TPR commands received from the base station. A fast-ramp-up behavior for adjustments of the authorized-TPR is followed when the authorized-TPR is less than the target-TPR. The down TPR commands are ignored in the adjustments of the authorized-TPR to allow following a fast-ramp-up behavior.
