    摘要： A method and system for de-coupling forward and reverse link assignment for multi-carrier wireless communication systems. A method may assign two or more forward link code division multiple access (CDMA) carriers to transmit data from a base station to an access terminal; assign one or more reverse link CDMA carriers to transmit data from the access terminal to the base station; and limit reverse link overhead transmissions corresponding to the two or more forward link CDMA carriers.

    摘要： Adaptive delay management means and method for allocating resources having different Quality of Service (QoS) requirements. A Forward Link (FL) scheduler prepares transmission instances by treating pending data queues according to a priority class, such as Best Effort (BE) and Expedited Forwarding (EF). Data bits from multiple queues are stuffed into a transmission instance. Various metrics are used to generate a set of candidates for transmission and then select and build a next transmission instance from the set of candidates.

    摘要： Disclosed are methods and apparatus for interference cancellation in a wireless communication system. In particular, the disclosed methods and apparatus provide for interference cancellation in a wireless device, including extending linear interference cancellation techniques, such as quasi-linear interference cancellation (QLIC), in the wireless device to a first orthogonal set, which may be a first quasi orthogonal function (QOF) set for a cdma2000 system to cancel interference from that set upon another desired QOF set. QLIC may also be extended to cancellation of signals from non-intended base stations as well. Accordingly, the present methods and apparatus afford reduced interference through QLIC by canceling signals due to either undesired QOF sets or non-intended base stations, which in turn results in an increase in forward link capacity.

    摘要： Techniques for improving the capacity of a wireless communications system using interference cancellation (IC). In an early decoding and IC aspect, a frame transmitted from a user to a base station may be decoded prior to the entire frame being received by the base station. The remaining portion of the frame may then be re-constructed at the base station prior to its reception, and cancelled from the receive signal to reduce the interference to frames received from other users. In a power control aspect for early decoding and IC, the power control target level at a local base station may be adjusted in response to successfully early decoding a frame, without affecting the overall outer loop power control operation. Further aspects include late decoding techniques for utilizing the IC of other users' signals to improve the probability of decoding a given user's frames, as well as techniques for traffic channel demodulation using channel re-estimation.
