    摘要： An Access Network (AN) can send an acknowledge message (ACK) to an Access Terminal (AT) to indicate that the AN has successfully decoded the data received in the first set of slots of the first data packet. The AN can send a negative acknowledge message (NAK) to the AT to indicate that the AN has not successfully decoded the data received in the first set of slots of a first data packet. Based upon receipt of the NAK, the AT can resend the data by sending a second set of slots of the first data packet containing redundant data. Based upon receipt of the ACK, the AT can send a first set of slots of another packet. The AT can gate off for a predetermined period of time after sending the first set of slots of a first packet and before sending a next set of slots.

    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.

    摘要： Techniques for generalized pilot interference cancellation in a communications receiver. In an exemplary embodiment, a residual pilot is cancelled from a post-traffic cancellation signal following initial first-pass pilot cancellation. Residual pilot cancellation is achieved by adding the first-pass cancelled pilot as earlier stored in memory back to the post-traffic cancellation signal, and pilot filtering the resulting signal to generate an improved pilot interference estimate. In an alternative exemplary embodiment, an arbitrary number of iterations may be applied to generate the pilot interference estimate by successively storing each generated pilot interference estimate in memory.

    摘要： Upon successful decoding of a first set of slots of a first data packet, an Access Network (AN) can send an acknowledge message (ACK) to an Access Terminal (AT) to indicate that the AN has successfully decoded the data received in the first set of slots of the first data packet. Upon unsuccessful decoding of the first set of slots of the first data packet, the AN can send a negative acknowledge message (NAK) to the AT to indicate that the AN has not successfully decoded the data received in the first set of slots of a first data packet. Based upon receipt of the NAK, the AT can resend the data by sending a second set of slots of the first data packet containing redundant data. Based upon receipt of the ACK, the AT can send a first set of slots of another packet.
