摘要： 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/I) 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. 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.

摘要： A method and apparatus for scheduling transmit rates and power levels for data in conjunction with a voice-data communication during conditions of soft and softer handoff. During conditions of no handoff, or hard handoff, an algorithm selects a slot reflecting a favored power level and transmission rate for transmitting the non-voice data on a supplemental channel. The slot is selected based upon the transmission power levels for voice-data transmitted by a base station to a remote station on a fundamental channel. The algorithm applies to softer handoff using information from all the sectors of a base station involved in the softer handoff. During soft handoff, instead of scheduling forward link transmission based on recent power and rate, or C/I information, data is continuously transmitted to the user at a power level based on average required power.

摘要： Methods and apparatus are presented for scheduling data packet transmissions during optimal channel conditions. In one method, data packet retransmissions are scheduled for transmission during favorable channel conditions when the target remote station is moving slowly, but are scheduled for periodic transmissions when the target is moving moderately or fast. In another method, long delays for retransmissions in a channel sensitive timing scheme are eliminated. In other methods, a combination of periodic and aperiodic retransmissions are used to achieve the desired frame error rate.

摘要： Method and apparatus for congestion control in a wireless communication system. In one embodiment, the status of a congestion bit indicates the type of adjustment, such as increase or decrease, to be performed at an access terminal to determine the next data rate for transmissions on the reverse link. The status of the congestion bit is determined by comparing a congestion parameter to a predetermined threshold. One embodiment implements an outerloop threshold having a margin with respect to the desired congestion metric threshold. The outerloop threshold is adjusted in response to comparing a measured congestion metric to the desired threshold. The outerloop threshold adjustment maintains the congestion metric to within a predetermined probability of exceeding the desired threshold.

摘要： Method and apparatus for congestion control in a wireless communication system. Individual target data rate values are assigned individual access terminals. The individual data rates of the access terminals are adjusted to achieve the corresponding individual target data rate values. If the target values are not achieved within a predetermined number of iterations, the individual data rate is adjusted. In one embodiment, the status of a congestion bit indicates the type of adjustment, such as increase or decrease, wherein the status of the congestion bit is determined by comparing a congestion parameter to a predetermined threshold. One embodiment implements an outerloop threshold having a margin with respect to the desired congestion metric threshold. According to one embodiment, a congestion indicator includes multiple bits, wherein at least one bit instructs the mobile station to use target values or else to adjust without regard to a target value.
