Abstract: A method for limiting peak transmit power in a CDMA communication system by transmitting a first communication signal having a first high transmit power region, and transmitting a second communication signal having a second high transmit power region. A first and a second communication signal are time offset to prevent the first and second high transmit power regions from occurring simultaneously. Time shifting only a portion of the first and second communication signals is also taught. The first and second communication signals can also include respective first and second low transmit power regions. The time offset can be selected to align one of the first and second high transmit power regions with one of the first and second low transmit power regions. The total transmit power signal can be determined and the time offset can be selected to minimize a peak level of the total transmit power signal. The communication signals are separated into a plurality of portions and portions of the first and second communication signals are time offset to re-order the sequence of transmission of the plurality of portions.

Abstract: A method (18) for scheduling packet data transmissions in a wireless communication system wherein a per-user Priority Function (PF) (24) is based on a channel condition indicated by a Rate Request indicator (RRI). The method also considers fairness criteria dictated by predetermined Quality of Service (QOS) requirements. In one embodiment, the rate request indicator is a Data Rate Request (DRR). In another embodiment, the rate request indicator is Carrier-to-interference (C/1) information. In the exemplary embodiment, the base station calculates a Priority Function (PF) for the multiple mobile users. Each PF is a function of the rate request indicator and the projected throughput of a given mobile user. In one embodiment, the predicted throughput is calculated by T'= (T') .

In the exemplary embodiment, the base station calculates a Priority Function (PF) for the multiple mobile users. Each PF is a function of the rate request indicator and the projected throughput of a given mobile user. The PF values allow the base station to schedule active mobile units having pending data. The scheduling produces an approximately equal share of the allocated transmission time to the multiple mobile stations.

Abstract: The present invention is a novel and improved method and apparatus for reducing peak to average ratio in a system using auxiliary pilot channels as described in the TIA/EIA TR45.5 "cdma2000 ITU-R RTT Candidate Submission" to the ITU for consideration in the third generation wireless communication systems. A first method proposed in the present invention to deal with the above stated problem is to alter the phase of the auxiliary pilot channels to reduce to prevent the auxiliary pilot channels from adding constructively. A second method proposed in the present invention to deal with the above stated problem is to gate out the portion of the auxiliary pilot channels that add constructively. The present invention also proposes a novel demodulator design for receiving signals using the modified auxiliary pilot signals.

Abstract: The present invention relates to wireless voice and data communication systems. More particularly, the present invention relates to novel and improved methods and apparatus for transmitting data traffic on a communication channel. One such method comprises the steps of packaging a data payload into a plurality of subpackets; transmitting a first subpacket to a remote station; if the channel conditions are optimal, transmitting a remaining portion of the plurality of subpackets to the remote station; and if the channel conditions are not optimal within a predetermined time duration, then transmitting a remaining portion of the plurality of subpackets during unfavorable channel conditions. The apparatus may comprise means for packaging a data payload into a plurality of subpackets; means for transmitting a plurality of subpackets to a remote station; means for deciding, after the means for transmitting a plurality of subpackets has transmitted a first subpacket, whether: if the channel conditions are optimal, to transmit a remaining portion of the plurality of subpackets to the remote station; and if the channel conditions are not optimal within a predetermined time duration, then to transmit a remaining portion of the plurality of subpackets during unfavorable channel conditions.
