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.

摘要： A method in a base station, for adapting Sounding Reference Signals (SRS) power control setting in a user equipment is provided. An SRS specific fractional pathloss compensation factor "α sounding " value is decided based on a specific purpose for using SRS received from the user equipment. The α sounding value is decided independent of a value of a data specific fractional pathloss compensation factor "α data " to be used for data transmission to the base station. The user equipment is informed to use the decided α sounding value for adapting the SRS power control setting in the user equipment. This enables the user equipment to send SRS, using power according to the adapted power control setting.

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.
