摘要： Method and arrangement in a base station for selecting a transmission parameter. The selected transmission parameter is used when sending a signal over a radio channel to a user equipment in a wireless communication network. The radio channel is allocated bandwidth for signalling. The method comprises the step of obtaining an estimation of the signal quality of the radio channel. Also, the allocation to the radio channel. Further yet, the method may comprise the step of calculating a signal quality margin, which signal quality margin is based on the bandwidth size. Still further, the method comprises the step of selecting the transmission parameter based on the estimated signal quality of the radio channel and the calculated signal quality margin.

摘要： The present invention relates to a solution for taking into account that the interference, which each of the transmission resource elements is affected by, may differ between the different transmission resource elements when determining an interference estimate by determining a mixed interference estimate, e.g. based on both reference symbols and data symbols. Furthermore, signalling from the network is also introduced which makes it possible to control what the mixed interference estimate should be based on.

摘要： Method and apparatus for enabling accurate link quality estimation of a wireless link between a sending node (400) and a receiving node (402). When the sending node receives link state reports from the receiving node, it estimates the current state of the wireless link. The sending node also determines a measurement adjusting parameter if the link state reports are deemed inaccurate in relation to the estimated link state, based on a deviation between the received link state reports and the estimated actual link state. The sending node then sends the determined measurement adjusting parameter to the receiving node, and the receiving node provides a link state report based on signal measurements adjusted by the measurement adjusting parameter. The adjusted link state report can then be used for link adaptation of the wireless link and/or for packet scheduling decisions.

摘要： A method and arrangement for estimating the current channel quality for a data transfer in a mobile network. In a sending system entity, a channel quality estimate (CQE) associated with a data transfer to a receiving system entity in a mobile communication network is adjusted. One or more probing packets are communicated 400 between the sending system entity and the receiving system entity, each probing packet being formatted according to a predefined combination of transmission parameters. Furthermore, is a Channel State Information (CSI) report received 404 from the receiving system entity, and the CQE is adjusted 406 based on the CSI report and which probing packets have been successfully communicated. By sending a sequence of probing packets, each formatted according to a predefined combination of transmission parameters, and not waiting for each packet to be acknowledged, a fast and accurate estimation of the current channel quality is achieved.
