Adaptive processing envelope based on power consumption
Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for reconfiguring a resource envelope allocated to a distributed unit (DU) or a radio unit (RU) based on power consumption at the DU or the RU. A virtual radio access network (VRAN) manager (e.g., a host platform for a VRAN) may perform baseband pooling to allocate a resource envelope to a DU or an RU. After an initial allocation of a resource envelope to a DU or an RU, the DU, the RU, or both may report an amount of power consumed during signal processing for one or more dimensions of the resource envelope. The VRAN manager may then reconfigure a resource envelope for the DU or the RU based on the power consumption at these devices (e.g., to minimize operating expenses (OPEX) or maximize utilization of the resource envelope).
