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.

摘要： A method in a node is disclosed. The method comprises receiving a signal, and obtaining a first oversampled received signal by sampling the received signal according to a symbol rate. The method further comprises estimating a first frequency offset based on the first oversampled received signal, the first frequency offset estimated using an estimation range limited to one of a bandwidth of the received signal or the symbol rate of the received signal, and obtaining a second oversampled received signal by sampling the received signal according to N times the symbol rate, wherein N is greater than 1. The method further comprises estimating a true frequency offset based on the first frequency offset estimate and the second oversampled received signal.

摘要： A method, performed in a receiver device, for decoding transmissions of a set of coded information bits from a transmitter. The method includes deriving received symbols from first received data and second received data. The received symbols are converted to sets of soft coded bit estimates. The sets of soft coded bit estimates are combined to form a combined set of soft coded bit estimates. The combined set of soft coded bit estimates are decoded to form a set of soft information bit estimates. The set of soft information bit estimates are converted to form a set of binary bits. A determination is made whether the set of binary bits has been correctly or incorrectly decoded. Interference cancellation is performed on the received data, and the method is repeated until either the set of binary bits has been correctly decoded or a predefined maximum number of iterations is reached.

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.
