摘要： Method and apparatus for enabling accurate link quality estimation of a wireless link between a sending node and a receiving node. 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 receiving unit or a transmitting unit of a wireless network, and method therefor, for facilitating noise and interference measurements on an air interface. The receiving unit includes: a network interface which obtains information relating to a time-varying layout of a silent resource element (RE) grid; an electronic memory having code in communication with the network interface which stores the information; and a processing unit in communication with the electronic memory that takes a presence of a silent RE grid into account in the reception of a control or a data channel. Information relating to a time-varying layout of a silent resource element (RE) grid is obtained and a presence of a silent RE grid is taken into account in the reception of a control or a data channel.

摘要： In one aspect of the teachings herein, a probability distribution is determined for the prediction errors determined from the differences between predicted and measured values of a quality parameter for a radio link between first and second radio nodes in a wireless communication system. In turn, the probability distribution is used to identify a prediction error value on which a link adaptation margin estimate is based, and the link adaptation margin estimate is provided for use in performing link adaptation, e.g., for use as a “back off” value for the predicted values of radio link quality which are used to make link adaptation decisions.

摘要： A network node and a method performed by a network node for adjusting antenna parameters of one or more antennas in a wireless telecommunications network is provided. First, the network node obtains signal strength values associated with the antennas for a number of user equipments in the wireless telecommunications network. Then, the network node determines an amount of user equipments of the number of user equipments having a signal strength value difference from two antennas that passes a determined threshold for the signal strength value difference, and adjusts at least one antenna parameter of at least one of the two antennas when the determined amount of user equipments passes a determined threshold for the amount of user equipments.
