  • Patent number: 12238581
    Abstract: A method and transition device for enabling communication of data between a remote radio unit and a central baseband unit in a wireless network. When detecting a first interface configuration used by the remote radio unit and a second interface configuration used by the baseband unit, the transition device configures interface functions, based on the first and second interface configurations. The interface functions are selected from a set of predefined interface functions associated with different interface configurations. The transition device then establishes a data flow between the remote radio unit and the central baseband unit over the transition device, and performs conversion between the first interface configuration and the second interface configuration for data communicated in the data flow, using the selected interface functions.

  • Patent number: 11716653
    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.

  • Patent number: 11690059
    Abstract: A method for configuring transmission order of uplink data, the method performed by a radio equipment (“RE”) of an access node. The RE has a RE controller (“REC”)-RE interface that communicatively couples the RE with a REC of the access node. The method includes receiving instructions from the REC that indicate a scheduling prioritization for transmission by the RE of uplink data between the RE and the REC over the REC-RE interface. The uplink data can be received by the RE on the radio interface. The method can further include transmitting the uplink data on the REC-RE interface according to the instructions, resulting in the scheduling prioritization of the uplink data.
