Abstract
Techniques for improving the capacity of a wireless communication system using interference cancellation (IC). In the early decoding and IC aspects, the frame transmitted from the user to the base station may be decoded before the entire frame is received by the base station. Then, to reduce interference to frames received from other users, the remainder of the frame may be re-configured at the base station prior to its reception and may be erased from the received signal. In early power decoding and IC power control aspects, the power control target level may be adjusted in response to successfully early decoding the frame without affecting the entire outer loop power control operation at the local base station. Additional aspects include rate decoding techniques to improve the probability of decoding a given users frames using ICs of other users signals, as well as techniques for traffic channel demodulation using channel re-estimates.
