Patent number: 9320053Abstract: Load measurements having low computational complexity are provided that give an effective load after interference suppression. The effective load after interference may be compared with the air interface load to determine interference suppression gains for different user constellations. The interference suppression gains may be stored in the form of a gain table that gives the expected interference suppression gains for different user constellations. The expected interference suppression gains may be used by a scheduler at a base station to predict the effective load for two or more candidate user constellations, and to select one of the candidate user constellations. Users are then scheduled according to the selected user constellation.Type: GrantFiled: December 8, 2011Date of Patent: April 19, 2016Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventor: Karl Torbjörn Wigren

Patent number: 9234959Abstract: A method for providing position determination assisting data comprises repetitions of establishing (210) of a cell relation configuration for a user equipment and performing (212) of a high-precision position determination for the user equipment. Results of the determinations belonging to the same cell relation configuration are clustered (214) in separate clustered results. An area definition is associated (220) with the clustered results by enclosing (221) the clustered results by a polygon, shrinking (222) the polygon by moving corners towards a contraction point and defining (223) the area definition as a shrunk polygon comprising a predetermined fraction of the clustered results. The contraction point is selected to be situated within the clustered results. The method also comprises creating (230) of position determination assisting data comprising a relation between the cell relation configurations and the associated area definitions.Type: GrantFiled: May 7, 2009Date of Patent: January 12, 2016Assignee: TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)Inventor: Karl Torbjörn Wigren

Patent number: 8712463Abstract: For power control in a wireless communication system, a node comprises means for obtaining power of signals received over a wireless signal channel and a power control signal unit. The power control signal unit (21) provides power control signals intended for the power control over the channel. A warper unit warps the power control signals by a first filter. A quantizer quantizes the warped power control signals, which are transferred to another node in the wireless communication system. The receiving node comprises a dewarper, dewarping the received signals by a second filter. The power control of the wireless signal channel is performed based on the dewarped power control signal. The filters are linear filters arranged for reducing an influence of quantization. The second filter is an inverse filter with respect to the first filter. The filters are preferably adapted by adaptors.Type: GrantFiled: March 5, 2008Date of Patent: April 29, 2014Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Graham C.
