Patent number: 10356637Abstract: 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.Type: GrantFiled: November 30, 2017Date of Patent: July 16, 2019Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: David Hammarwall, George Jöngren, Magnus Lundevall

Patent number: 10298354Abstract: The application relates to the selection of cells to form a cell coordination group for which interference management techniques such as COMP are to be applied. The cells to be selected to improve the performance of a UE in terms of throughput or delay are not necessarily the ones which are geographically the closest because in city environments shadowing effects of buildings exist. Thus, choosing the closest cells for coordinated interference management will not be a good solution in many cases. Hence, there is a need to develop another method and mechanism for more accurately generating a cell coordination group for interference management activities. This problem is solved by the application in that either the downlink interference toward the UE from the neighboring cells is estimated or the neighbor cells listen for the UE and then predict the downlink interference. Furthermore, the algorithm starts with an initial list of cells comprising the most likely handover candidates.Type: GrantFiled: August 21, 2014Date of Patent: May 21, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Fredric Kronestedt, Lars Klockar, Magnus Lundevall
