Patent number: 11716653Abstract: A transport path group for uplink transmission over a fronthaul interface. The transport path group may include (i) an address of a first source port of a radio unit (RU), (ii) an address of a first destination port of a distributed unit (DU), and (iii) an address of a second source port of the RU, an address of a second destination port of the DU, and/or a flow identifier (e.g., a virtualized local area network (VLAN)). A request for user data conveyed by the DU and received by the RU may identify the transport path group. The RU may use the fronthaul interface to convey to the DU first and second portions of the requested user data over first and second different paths from the RU to the DU. The RU may employ load balancing parameters to convey the first and second portions of the requested user data.Type: GrantFiled: January 7, 2022Date of Patent: August 1, 2023Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Jacob Österling, Murali Krishna Srinivasan, Lars Hennert, Göran Knutson, Patrik Nordensky, Michael Persson
