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： In a first aspect the present invention relates to a method of compensating for propagation delay in a wireless communication system. A first base station is in communication with a first plurality of antenna units which are adapted to be in wireless communication with a first terminal. The first terminal having a terminal antenna. The first plurality of antenna units is spatially separated. The method according to the first aspect comprises the steps of determining relative propagation delay from each of the first plurality of antenna units to the terminal antenna and using the determined propagation delay to establish a delay profile to compensate for propagation delay from each of the antenna units to the first terminal and applying the delay profile to a transmission between the base station and the terminal. In a second aspect the present invention further relates to a system implementing the method according to the first aspect.
