  • Publication number: 20250113311
    Abstract: The technology described herein is directed towards runtime dynamic downlink power configuration between a distributed unit and radio unit. In one O-RAN-compliant implementation, control-plane messages are used to update the downlink power without any service interruption, based on initialization information provided by management-plane messages to the distributed unit, including a radio unit's indication of support for the power change and the time (gap) needed by the radio unit to implement a power change. Based on this data, the distributed unit and radio unit (which are synchronized) change the downlink power at the same specific time (same symbol) such that the power configuration can be done during runtime without any service interruption. This is advantageous with power changes needed for Citizens Broadband Radio Service (CBRS) systems and/or for energy saving purposes, for example.

  • Publication number: 20240380506
    Abstract: Radio unit equipment that facilitates radio unit time alignment and delay characterization includes a buffer that stores input data received via a signal ingress point of the radio unit equipment, resulting in buffered data. The radio unit equipment also includes clock generation logic that provides a synchronized frame number (SFN) pulse to the buffer. The buffer releases the buffered data at a time corresponding to the SFN pulse and modified by a timing adjustment parameter, resulting in the buffered data proceeding from the buffer to a signal egress point of the radio unit equipment. Additionally, the buffer determines the timing adjustment parameter based on a defined signal propagation delay between the buffer and the signal egress point of the radio unit equipment.

  • Publication number: 20240107592
    Abstract: The described technology is generally directed towards interoperability between distributed units (DUs) and radio units (RUs) in a radio access network (RAN) network. Various embodiments are presented to enable automated determination and/or automated implementation of various configurations and functionalities on a physical random access channel (PRACH) between a DU and a RU. The automated operations presented herein enable a DU to discover and verify PRACH functionality (e.g., regarding PRACH time offset) supported by a RU and/or implementation of the PRACH functionality at the RU to enable interoperability between the DU and the RU, thereby satisfying the interoperability requirement of the O-RAN specification.
