  • Methods and Apparatuses for Operating a Radio Unit During Loss of Connection in a Radio Access Network
    Publication number: 20250048479
    Abstract: Techniques are described for mitigating the negative effects of temporary loss of connectivity or temporary loss of service between a RU and a BU. In embodiments of the present disclosure, the radio unit is configured to transmit reference signals during a temporary loss of connectivity with the baseband unit to allow the UEs served by the radio unit to maintain synchronization with the radio unit and avoid or minimize radio link failures. Applying these techniques, the UEs served by the radio unit can maintain connection with the radio unit during the temporary outage and avoid the need to engage in Radio Resource Control (RRC) signaling to re-establish a connection with the radio unit and/or handover to neighboring radio units.

  • First node, second node, fourth node and methods performed thereby in a communications network
    Patent number: 12166664
    Abstract: A method performed by a first node. The first node operates in a communications network. The first node determines, based on a header of a packet, a first number of hops. The first number of hops are the hops the packet has to traverse in the communications network to reach a second node in the communications network. The header of the packet indicates a second number of hops between the second node and a third node in the communications network in a first path. The first node obtains a wired backhaul connection to a core network of the communications network from the third node. The first node then initiates routing the packet towards the second node based on the determined first number of hops.
