摘要： A method includes determining channel quality feedback information characterizing the channels statistically and calculating, based on the channel quality feedback information, a robustness related measure, such as outage capacity, associated with an on- frequency mode of operation and a robustness related measure, such as an outage capacity, associated with a frequency translated mode of operation. The method includes selecting the on-frequency mode of operation or the frequency translated mode of operation that maximizes the robustness related measure, such as outage capacity. The method also includes transmitting a message to other devices to operate in the selected on-frequency or a frequency translated modes. The method also includes performing maximum ratio combining or interference rejection combining, by at least one of the other devices, when the message indicates to operate in the frequency translated mode.

摘要： Methods and apparatuses for enabling frequency selective repetition of signals in a telecommunication system in which aggregation of component carriers is applied. Information signals are received (1102) in a first set of frequency bands, which is defined to cover anchor carriers, which can be used by both legacy and non-legacy terminals. Further, information is received (1104) in a second set of frequency bands, which is defined to cover non-anchor carriers, which only can be used by non-legacy terminals. Instructions concerning which frequency band(s) that should be repeated by the repeater node, are also received (1106). Thereafter, the frequency bands indicated in the instructions are filtered out (1110), after which these frequency bands or parts are repeated by the repeater node. This results in enabling frequency selective repetition in a system which may comprise legacy mobile, which limits the interference in the system, which enables higher bitrates and saves energy.

摘要： A method and arrangement in a first node (101) for determining radio characteristics of a radio link between a first repeater (103, 203) and at least one second repeater (104, 204) are provided. The first node sends a first message, to the first repeater (103, 203), instructing the first repeater (103, 203) to send a radio signal being measureable by the second repeater (104, 204). Furthermore, the first node sends a second message, to said at least one second repeater, instructing said at least one second repeater (104, 204) to measure on the radio signal. The first node receives measurement data of the radio signal, measured by said at least one second repeater (104, 204). The first node (101) determines radio characteristics of the radio link between the first repeater (103, 203) and said at least one second repeater based on the measurement data. Methods and arrangements in a first and second repeater and a method and arrangement in a second node for contributing to radio characteristics determination are provided.

摘要： In a receive node (230) of a wireless network (100), an iterative multi-user multi-stage interference cancellation receiver (500, 1400, 1700) is used. The receiver (500, 1400, 1700) 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.
