Distributed unit scheduling for radio unit-based custom traffic insertion

Abstract

The described technology is generally directed towards scheduling, by a distributed unit, the injection of custom traffic (signals/data) by a radio unit into a radio unit communications path. The scheduling can be such that the custom traffic can be interleaved with to live-air and/or non-live-air traffic, for example. The radio unit can request unscheduled physical resource blocks for custom traffic to be inserted by the radio unit, and the distributed unit can communicate the timing and scheduling (identify the unscheduled physical resource blocks) to the radio unit in response to the request. The custom traffic is configured to perform some action by the radio unit, such as to perform antenna calibration, to perform test and measurement operations to obtain performance data, and the like. Performance data can be used, for example, to modify operating parameters of the radio unit to improve performance of the radio unit.
