Patent number: 8831599Abstract: The present invention provides a method and respective entities for avoiding handovers in a ping-pong manner in a communication network. The method comprises comparing, when a handover of a mobile station to a base station is intended, decision criteria of the intended handover with decision criteria of previous handovers of the mobile station to that base station, and deciding on allowing or preventing the intended handover based on the result of the comparison.Type: GrantFiled: June 29, 2007Date of Patent: September 9, 2014Assignee: Nokia CorporationInventors: Lauri Kuru, Petri Jolma, Zexian Li, Jarmo Makinen, Roman Pichna

Patent number: 8010138Abstract: A host base transceiver station BTS derives a reference timing signal from a physical layer training signal (such as a preamble) received from a neighbor network node/BTS. Downlink transmissions are then synchronized to the derived reference timing signal. This may be used as a holdover timing mode, such as when the host BTS determines that synchronization from a primary source is no longer reliable. In an embodiment, a reference oscillator of the host BTS is phase locked to the derived reference timing signal. Variations include one or multiple such training signals from one or multiple neighbor BTSs, selecting one BTS when the primary synchronization mechanism fails for several BTSs in the same area, and how to phase lock the oscillator without dithering about the target frequency. Apparatus and computer programs are also detailed.Type: GrantFiled: August 15, 2007Date of Patent: August 30, 2011Assignee: Nokia CorporationInventor: Lauri Kuru

Publication number: 20090262793Abstract: Insight and rules are needed for how to handle scheduling in a way meaningful for network operation is explained, such as what transmissions can be delayed for scheduling and which cannot be delayed for scheduling, and how grouped transmissions can be used for interference avoidance. Certain embodiments of the present invention provide a solution to these and other problems. In certain embodiments of the present invention, for example, users are grouped according to criteria which may be indirectly related to interference but are nevertheless different from interference. Thus, for example, certain embodiments of the present invention use expected receive or transmit signal strength or use MCS as grouping criteria.Type: ApplicationFiled: April 17, 2008Publication date: October 22, 2009Inventors: Thomas Hohne, Petri Jolma, Lauri Kuru, Antti Sevon

Publication number: 20050282570Abstract: The objective of the invention is to increase the potential hop density of single frequency TDD radio links by allowing a set of closely located terminals to use a single channel. This is possible when transmission and reception periods of the terminals are synchronized so that the transmit period of any of the terminals in a terminal group does not overlap with the receive period of any of the terminals in the group. Synchronization is achieved by selecting at least one terminal in a hub site as a super master terminal. This terminal gives timing through a common bus to the rest of the terminals in the group These terminals use the received timing for adjusting their own timing i.e. for adjusting the starting moment and ending moment of the transmission and reception periods in such a manner that none of terminals is sending a burst while another terminal is receiving.Type: ApplicationFiled: August 29, 2005Publication date: December 22, 2005Inventors: Otto Pulkkinen, Jarmo Makinen, Lauri Kuru
