Publication number: 20240007205Abstract: A Transmission Reception Point (TRP 22) of a wireless communication network (10) operates with a Time Division Duplexing (TDD) configuration for downlink and uplink communications, and a network node (18) detects a trigger condition for adapting the TDD configuration, with the trigger condition at least including detection of an impairment condition arising from periodic fading on one or more of the radio links between the TRP and User Equipments (UEs 12). For example, the network node (18) determines that the impairment condition exists and satisfies one or more additional criteria, and, in response, adapts the TDD configuration of the TRP, to improve the responsiveness of Link Adaptation (LA) by the TRP (22). An advantageous recognition underlying responsive adaptation of the TDD configuration is that the TDD configuration of the TRP (22) influences the LA time constant or convergence time of the LA algorithm used by the TRP (22).Type: ApplicationFiled: February 21, 2020Publication date: January 4, 2024Inventors: Peter Ökvist, Kjell Larsson

Patent number: 11784698Abstract: A method for beam assignment support comprises obtaining of, in a radio base station, a set of channel gain estimations representing potential transmissions in a set of beams to a user equipment. A set of bias values is obtained, representing connection quality predictions for a respective beam of the set of beams for transmission to the user equipment. The connection quality predictions are estimations calculated from measures of previous traffic load, previous radio quality of transmissions, and/or previous beam assignments of the first transmission reception point. A set of biased channel gain estimations is determined by weighting the channel gain estimations in dependence of respective bias values. A beam assignment based on the biased channel gain estimations is initiated. A method also for determining bias values in a network node as well as radio base stations.Type: GrantFiled: December 21, 2017Date of Patent: October 10, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Tomas Lundborg, Kjell Larsson, Andreas Ermedahl

Patent number: 11736537Abstract: A user terminal emulation server maintains a database identifying network addresses, UI capabilities, and communication protocols of I/O user devices. Communication sessions are established between a user terminal emulation application and a network entity and I/O user devices proximately located to a user and provide a combined I/O user interface. Delay profiles are determined between the application and the I/O user devices. A downlink flow from the network entity is split into a plurality of downlink flow components assigned to the I/O user devices. For each of the downlink flow components, the server formats the component for transmission to the assigned I/O user device, initiates transmission of the formatted downlink flow component to the assigned I/O user device, and controls timing for when the formatted downlink flow component is transmitted to the assigned I/O user device based on the delay profile associated with the assigned I/O user device.Type: GrantFiled: June 11, 2019Date of Patent: August 22, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Hans Hannu, Peter Ökvist, Tommy Arngren, Stefan Wänstedt, Kjell Larsson
