“…This model considers the contributions referred to RAN, backhaul/fronthaul, edge, core, and data centers during downlink communications. Moreover, it includes a detailed characterization of baseband processing requirements because of UEs, provided by Werthmann et al 27 Sections 3.2 and 4. Since 5G KPIs are not to be satisfied singularly but concurrently, the analysis in terms of power consumption and energy efficiency is drawn up to an evaluation of latency.…”

“…Next, the power consumption P dc depends on the number of switches and servers, which compose the data center; in particular, the number of processing servers depends on the processing load, required by each mobile user at a specific time. This load can be estimated as 27 pUE=()3A+A2+13MCLR10, where A is the number of antennas, M is the modulation bits, C is the code rate, L is the number of spatial MIMO‐layers, and R is the number of physical resource blocks (PRBs). The processing load p UE is measured in GOPS.…”

The indicator when the user of is processed by and , otherwise where, used to minimize the number of BBUs that illustrated in equation (11). Equation (12) ensures that the users for can be processed by either a single or multiple BBUs .…”
