Patent number: 9191847Abstract: A radio base station transmits data symbols to a mobile terminal on multiple frequency carriers, e.g., in accordance with the MC-WCDMA or cdma2000 3x air interface protocols. The radio base station instructs the mobile terminal to report channel quality measurements obtained by the terminal for the multiple carriers over the same uplink channel during successive reporting intervals. According to one embodiment, the mobile terminal reports channel quality by receiving data symbols transmitted on a plurality of frequency carriers in a multi-carrier CDMA environment and measuring channel quality for the different frequency carriers. The mobile terminal reports individual ones of the channel quality measurements over the same uplink channel during successive reporting intervals.Type: GrantFiled: June 18, 2014Date of Patent: November 17, 2015Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Stefan Parkvall, Erik Dahlman, Bo Göransson, Joakim Bergström

Patent number: 8380196Abstract: A method and arrangement for handover wherein the handover resource (the dedicated random access preamble) is reserved by the target radio base station (RBS) for a limited period of time, thus increasing the handover efficiency and thereby allowing random access preambles to be used for initial access to a larger extent. The information about the reserved time interval is sent to the UE in the handover command message by means of a frame number offset between the source RBS and the target RBS. The UE uses the information to calculate when to send its synchronization message to the target RBS. The frame number offset is calculated either by source RBS or by target RBS.Type: GrantFiled: February 27, 2008Date of Patent: February 19, 2013Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: András Rácz, Gunnar Mildh, Joakim Bergström, Magnus Lindström

Patent number: 8270976Abstract: The present invention relates to a method for use in a user equipment (10), and relates to a user equipment (10) for enabling a serving base station (40) to estimate interference contribution in a network when scheduling resources for the use equipment. According to the method, the user equipment determines an amount of resources required to send data and the user equipment sends a report to it serving base station when the required amount of resources is greater than a threshold value. In the report, measurements performed by the user equipment are included. The report will assist the serving base station with its estimation of the degree of interference user equipments generates in the network, and hence the power and resources to assign.Type: GrantFiled: June 12, 2008Date of Patent: September 18, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Arne Simonsson, András Rácz, Janne Peisa, Joakim Bergström
