  • METHODS AND NODES IN A COMMUNICATIONS NETWORK
    Publication number: 20240172283
    Abstract: A computer implemented method performed by a first node in a communications network for use in determining whether a channel between the first node and a target node is in use. The method includes selecting, from a plurality of other nodes that are suitable for making measurements on the channel, a subset of the other nodes from which to obtain channel information in order to determine whether the channel is in use. The selection is performed using a first model trained using a first machine learning process to select the subset of other nodes based on accuracy of the resulting determination of whether the channel is in use. The method then includes sending a message to cause the subset of other nodes to obtain the channel information.

  • Techniques for conditional handover and bi-casting
    Patent number: 11968588
    Abstract: Embodiments include methods performed by a network node, in a radio access network, RAN, that is a target node candidate for a mobility operation of a user equipment, UE. Such methods include receiving, from a source node serving the UE, a request to prepare a mobility procedure for the UE in relation to a candidate target cell associated with the network node. The request can include characteristics associated with a data connection of the UE. Such methods include determining that the UE can be admitted for the requested mobility procedure based on the characteristics, and determining to activate bicasting of the data connection. Different bicasting modes can be selected. Such methods also include transmitting, to the source node, a response that includes a bicasting configuration associated with the UE. Other embodiments include complementary methods performed by source nodes, as well as network nodes configured to perform such methods.

  • Method and apparatus for wireless device synchronization in a beam-based communication system
    Patent number: 11871218
    Abstract: Among other things, the method and apparatus examples herein provide a solution to the problems that arise regarding the need for a wireless device to achieve source synchronization in a beam-based system, where the wireless communication network does not define “cells” for connected-mode wireless devices. The problems relate to how a wireless device can re-synchronize with its source access node in a beam-based system that mainly relies on self-contained transmissions from transmission points in the network. As one example advantage, the contemplated methods and apparatus enable wireless devices to perform measurements to support mobility procedures even when no data transmissions are scheduled.

  • First network node, second network node, wireless device and methods performed thereby for handling a link switch
    Patent number: 11683731
    Abstract: A method, performed by a network node. The method is for handling a switch of a wireless device from a source to a target link. The network node and the device operate in a wireless communications network. Given a configuration of the target link indicating resources to perform random access to the network node during the switch, the network node, transmits, prior to the switch, an indication to the device. The indication indicates an update to the configuration. The network node changes the configuration of the target link, based on the update. The changing is performed only after receiving a confirmation of at least one of: i) from the device, that the device has received the indication, and ii) from a first network node operating in the wireless communications network, that it has transmitted the indication to the device.

  • Methods and apparatuses for performing new radio cell selection/re-selection
    Patent number: 11601859
    Abstract: A user equipment (UE) operates to select and/or re-select among radio cells provided by access nodes of a wireless communication system. The UE measures quality of beams detected from each of the cells. For each of the cells, the UE derives cell quality based on the quality of the beams from the cell. For each of the cells, the UE determines the number of good beams among the beams from the cell based on a cell quality threshold received via system information. The UE ranks the cells in a ranking list relative to each other based on the number of good beams associated with respective ones of the cells and the cell quality. The UE controls, based on the ranking of the cells in the ranking list the number of good beams and the cell quality, selection and/or re-selection of a cell among the cells that is to be used for UE radio communications.
