Patent number: 10531399Abstract: Radio resources like spreading codes and transmission power are optimally allocated to various different types of radio channels supported in the cell including a specialized channel like a high-speed shared channel. One or more measurements made at the base station are provided to the radio resource manager. Such measurements include other-channel power, high speed shared channel code usage, high speed shared channel transport format usage, average active load on the high speed shared channel, empty buffer, excess power, and similar parameters that relate to a high speed shared channel. One or more of these reported measurements may then be used to access, allocate, and/or to regulate resources associated with the base station's cell.Type: GrantFiled: January 22, 2016Date of Patent: January 7, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Niclas Wiberg, Eva Englund, Sharokh Amirijoo, Gert-Jan van Lieshout, Per Beming, Stefan Parkvall, Patrik Karlsson

Patent number: 9504019Abstract: According to the invention data in a number of logical downlink intended for one or more mobile terminals are received in a first mapping unit, where at least a first High Speed Radio Network Temporary identity is allocated to these logical downlink channels addressing a group of mobile terminals for allowing transmission of channel data for reception by mobile terminals. A mobile terminal then reads, from a Broadcast Control Channel, necessary information including a High Speed Radio Network Temporary identity allocated to at least one logical downlink channel, where at least said first identity exists among possible identities. It then listens to a high speed shared control channel for the read identity. In case it detects the identity, the terminal follows a scheduling command, receives data on a high-speed downlink shared channel and processes said data.Type: GrantFiled: July 31, 2015Date of Patent: November 22, 2016Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Per Beming, Janne Peisa, Mats Sågfors, Johan Torsner, Stefan Wager

Patent number: 8514694Abstract: A network informs a user equipment about the number of usable sub-carriers in a frequency spectrum. Based on this, and its knowledge of a generic size of a resource block, the user equipment is able to determine a number of sub-carriers that are to be allocated to one or more fractional resource blocks. Rules, which may be predefined in the standard, or may be signalled to the user equipment, allow the user equipment to determine which of the usable sub-carriers should be allocated to the fractional resource block or blocks.Type: GrantFiled: August 27, 2007Date of Patent: August 20, 2013Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Dirk Gerstenberger, Stefan Parkvall, Per Beming, Erik Dahlman

Patent number: 8085697Abstract: An object of the present invention is to provide an improved real-time application performance for user equipments. The object is achieved by a method for bi-casting real time data packets in a mobile system node. The node is comprised in a mobile system, which mobile system comprises an old Node-B and a new Node-B. The old Node-B and the new Node-B are adapted to be connected to the node. The mobile system further comprising a user equipment 130 adapted for switching the receipt of real time data packets from the old Node-B to the new Node-B. The method comprises the steps of associating a first sequence number with a first real time data packet adapted to be sent to the old Node-B, and associating a second sequence number with the same first real time data packet adapted to be sent to the new Node-B. The second sequence number is different from the first sequence number.Type: GrantFiled: May 2, 2006Date of Patent: December 27, 2011Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Karl Olof Joakim Bergström, Per Beming

Patent number: 8014772Abstract: Procedures are provided for the establishment of MBMS services in different cells of a cellular telecommunications network, in particular, for maintaining the transmission of MBMS data to a particular user equipment, even when it moves from one cell to another when the service is provided in different ways in different cells. In particular, when a user equipment receives a multimedia data service in a first cell via a certain type of connection (i.e., a point-to-point connection/while requiring an RRC Connection, a point-to-multipoint connection without/while requiring an RRC Connection), and moves to a second cell where the type of connection used to provide the service is different, specific actions are undertaken (e.g., request for an RRC Connection, release of an RRC Connection, etc), depending on the type of connection change carried out. Embodiments for the establishment of the most adequate connection (p-t-p, p-t-m) in a cell are disclosed as well (e.g., by sending a message from a SRNC to a CRNC).Type: GrantFiled: January 7, 2009Date of Patent: September 6, 2011Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Per Beming, Elena Voltolina, Gert-Jan Van Lieshout

Patent number: 7920888Abstract: A radio network entity in charge of outer loop power control for a communication with a mobile radio is informed about erroneous data units, requested retransmissions, and/or data units transmission attempts associated with the data units sent by the mobile radio to the radio network. Another radio network entity, which sends a transmission power control signal to the mobile radio to control the mobile's transmit power level based on a target value, detects errors in data units received from the mobile radio and requests retransmission. Information associated with the requested retransmission is used to generate a revised target value. The target value may be revised by an outer loop power controller node or by an outer loop power controller entity in the same node as an ARQ entity that generates the information about erroneous data units, requested retransmissions, and/or data units transmission attempts associated with the data units sent by the mobile radio to the radio network.Type: GrantFiled: April 6, 2004Date of Patent: April 5, 2011Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Per Beming, Stefan Parkvall, Kai-Erik Sunell, Eva Englund

Publication number: 20100040022Abstract: A method and apparatus for reducing handover interruptions when a mobile device executes handover including a random access procedure is described herein. When handover is desirable, a time offset associated with a random access opportunity is determined. The time offset relates the timing of the next random access opportunity to the frame timing of a target access point. Based on the time offset, a network element, e.g., the mobile device, a serving access point, or a mobility management entity, determines a handover start time. Handover is executed at the determined start time to generally align the beginning of the handover execution with the beginning of the next random access opportunity, and therefore, to reduce handover interruption.Type: ApplicationFiled: January 14, 2008Publication date: February 18, 2010Applicant: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Magnus Lindstrom, Per Beming, Gunnar Mildh, Joakim Bergstrom, Walter Muller
