Publication number: 20240015530Abstract: Embodiments of the present disclosure relate to routing in integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, two or more IAB donors share topology information for inter IAB network routing. The IAB donors allocate addresses to IAB nodes with dual connectivity based on the topology information. In this way, it avoids address collisions when routing in the inter IAB networks.Type: ApplicationFiled: November 4, 2020Publication date: January 11, 2024Inventors: Matti LAITILA, Xiang Xu, Henri KOSKINEN, Ilkka KESKITALO, Esa MALKAMAKI

Publication number: 20230328625Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for transferring traffic in integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, a first Central Unit-Control Plane (CU-CP) of a first IAB donor transmits, to a second CU-CP of a second IAB donor, a request to transfer target traffic via a Distributed Unit (DU) of the second IAB donor. The request comprises first information of the target traffic. The first CU-CP receives, from the second CU-CP, second information to be used for configuring the target traffic. This solution can improve the reliability and robustness of the IAB communication.Type: ApplicationFiled: October 22, 2020Publication date: October 12, 2023Inventors: Xiang XU, Henri KOSKINEN, Matti LAITILA, Esa MALKAMÄKI, Osman YILMAZ, Oliver BLUME, Ilkka KESKITALO

Patent number: 9485630Abstract: The present invention relates to methods and devices for enabling reception of a specific service for terminals idle mode. More particularly, the present invention relates to such methods and devices enabling mobility for terminals in idle mode so as to receive an MBMS service. In case a terminal is interested in the MBMS service, it applies different reselection rule than normal reselection rule i.e., when the terminal is not interested in the MBMS service. For instance, the terminal manipulates the priority indications received from an eNB and considers MBMS layer the highest priority in case the terminal is interested in MBMS service. If the terminal thus manipulates the priority due to the (intended) MBMS reception, the terminal starts an MBMS timer, which is received as a permission parameter from the eNB.Type: GrantFiled: April 28, 2011Date of Patent: November 1, 2016Assignee: Nokia Solutions and Networks OyInventors: Woonhee Hwang, Henri Koskinen
