Abstract: A system and method for a time-scalable priority-based scheduler. A flexible scheduling algorithm utilizing variable scheduling durations enables better system capacity utilization. A rate request is transmitted if data arrives in a buffer, data in the buffer exceeds a buffer depth, and sufficient power exists to transmit at the rate requested. A rate assignment responsive to the rate request indicates a scheduled duration and a scheduled rate applicable for the scheduled duration. The scheduled duration is less than or equal to a scheduling period. The scheduling period is an interval of time and after which a scheduler makes a scheduling decision. The scheduling period is variable and the scheduled duration is variable.

Abstract: A mobile wireless telecommunications system includes base stations of a first type operating according to a first air interface, and base stations of a second type operating according to a second air interface. Methods and apparatus are provided for handing over a mobile station in the system from a first base station, which is of the first type, to a second base station, which is of the second type. A communications link is established over the first air interface between the mobile station and the first base station. Data are received from the mobile station responsive to a signal received by the mobile station over the second air interface from the second base station, substantially without breaking the communications link with the first base station. The mobile station is handed over from the first to the second base station responsive to the data received therefrom. In particular, a method of conducting intersystem handover from a multicarrier system to a direct spread system is provided. Timing synchronization is also advantageously made available through the mobile station.

Abstract: Techniques for power control of serving and non-serving base stations are disclosed (104). In one aspect, power control commands for a plurality of base stations (104) are combined to form a single command to control the plurality of remote stations (740). In another aspect, an "Or-of-up" rule is used to combine the power control commands. In yet another aspect, a channel quality indicator is used to power control a serving base station (730). Various other aspects are also presented. These aspects have the benefit of providing efficient power control between a mobile station and both serving and non- serving base stations, thus avoiding excessive interference and increasing capacity.

Abstract: 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 (208, 218). 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 increas e or decrease (204), wherein the status of the congestion bit is determined by comparing a congestion parameter to a predetermined threshold. One embodimen t implements an outerloop threshold having a margin with respect to the desire d 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 (210, 216).

Abstract: A channel structure and mechanisms that support effective and efficient allocation and utilization of the reverse link resources. In one aspect, mechanisms are provided to quickly assign resources (e.g., a supplemental channel) as needed, and to quickly de-assign the resources when not needed or to maintain system stability. The reverse link resources may be quickly assigned and de-assigned via short messages (412, 418) exchanged on control channels on the forward and reverse links. In another aspect, mechanisms are provided to facilitate efficient and reliable data transmission. A reliable acknowledgment/negative acknowledgment scheme and an efficient retransmission scheme are provided. Mechanisms are also provided to control the transmit power and/or data rate of the remote terminals to achieve high performance and avoid instability.
