Abstract: 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.

Abstract: A method for multi-path packet scheduling in a wireless communication system comprises collecting of measurements of queue state information about buffers of a plurality of transmit nodes. A rate budget is calculated based on the collected measurements of queue state information. The rate budget comprises commanded bit rates and/or data volumes for each transmit node for a subsequent sampling period. Data representative for the rate budget is provided from the packet-flow controller node over a packet scheduling interface to a packet scheduler node. Packets to be sent to each of the plurality of transmit nodes in a subsequent sampling period are scheduled depending on the received rate budget. Nodes for multi-path packet scheduling in a wireless communication system are also disclosed.
