  • Retransmission protocol feedback handling with multiple feedback times
    Patent number: 11750337
    Abstract: In a mobile network, the transmission of downlink data blocks to one or more terminal devices is accomplished on the basis of a retransmission protocol with a first feedback time defining a time interval between transmission of a first data block and transmission of a first feedback message being different from a second feedback time defining a time interval between transmission of a second data block and transmission of a second feedback message. The first feedback message indicates whether the first data block was successfully received, and the second feedback message indicates whether the second data block was successfully received. A base station of the mobile network controls the terminal device to send the second feedback message on other resources than used for transmission of the first feedback message.

  • Communication node and method performed therein for controlling transmission
    Patent number: 11742983
    Abstract: Embodiments herein relate to, e.g., a method performed by a communication node for controlling one or more communication parameters of a channel between a first communication device and a second communication device in a wireless communication network. The communication node, upon obtaining an indication of a channel quality of the channel to the second communication device, uses a correction value and the indication when determining the one or more communication parameters. The correction value is based on a decoding success of one or more previous transmissions, which one or more previous transmissions are based on an obtained previous indication of a previous channel quality from the second communication device, and wherein a change of the correction value relative a previous correction value is limited.

  • Inter-CU Migration in IAB Network
    Publication number: 20230269644
    Abstract: A source Integrated Access Backhaul, IAB, node (20) sends a handover request (110) from the source IAB node (20) to a target IAB node (30) to which a Mobile Termination, MT, (10) of an IAB node is to be migrated. The handover request (110) comprises an indication of a proxied inter donor IAB node migration of the MT (10) to the target IAB node (30). In some embodiments, according to the indication of the proxied inter donor IAB node migration, a radio resource control, RRC, connection of the IAB node is to be migrated to the target IAB node (30) but F1 connections and RRC connections of any children nodes served by the IAB node are to be kept at the source IAB node (20). In any event, the target IAB node (30) correspondingly receives the handover request (110) and sends a handover response (115) to the source IAB node (20).
