Abstract
The described technology is directed towards conveying, from a distributed unit to a radio unit, orthogonal frequency division multiplexing (OFDM) symbol-related data for each symbol of a slot for downlink transmissions by the radio unit. The symbol-related data includes information about each OFDM symbol's power, and the highest order of modulation used per symbol. The conveyed data can indicate a totally blank OFDM symbol. The per-slot symbol-related data can be conveyed in a control plane message to the radio unit, which, in an Open-Radio Access Network (O-RAN) network, can be formatted as a control plane section message type. Based on the slot information, a radio unit can configure the radio unit's power amplifiers, perform crest factor reduction, and/or digital pre-distortion tuning according to dynamic changes in the incoming downlink traffic, which can result in significant reduction in the power amplifiers' power consumption to boost the radio unit's overall energy efficiency.
