摘要： Network node (110), and method (300) in a network node (110), for load control in a cell (130) in a wireless communication system (100). The method (300) comprises starting an interference cancellation process, for reducing interference between uplink signals, estimating an interference cancellation gain, relative to an interference reduced received uplink signal power resulting from the interference cancellation process, wherein the interference cancellation gain is estimated after the start of the interference cancellation process but before the interference cancellation process is completed. In addition, the method (300) comprises controlling the traffic load of the cell (130), by considering the estimated interference cancellation gain.

摘要： In a receive node of a wireless network, an iterative multi-user multi-stage interference cancellation receiver is used. After each stage of interference cancellation, interference characteristics change. An adaptive finger placement strategy is used in which after each stage of interference cancellation, finger delays and combining weights of the receiver are adapted to reflect the changed interference characteristics.

摘要： In a receive node of a wireless network, an iterative multi-user multi-stage interference cancellation receiver is used. The receiver performs code-averaged equalization and chip chip-level code-specific interference over-cancellation on the received signals. This can result in a unified interference cancellation processing, and can avoid cumbersome calculations of code cross correlations that is required in symbol-level interference cancellation. A symbol-level code-averaged desired signal add-back is performed to address the over-cancellation of some desired signals.
