Facilitating energy-efficient wireless communications for advanced networks (e.g., 4G, 5G, and beyond) with low-resolution digital-to-analog converters is provided herein. Operations of a system can comprise determining first values. Respective values of the first values can be digital samples of transmission and reception chains determined based on symbols transformed from bits. The operations can also comprise facilitating a quantization of the first values resulting in second values. Facilitating the quantization can be based on a cost function associated with processing the first values. Further, the operations can comprise outputting the second values as a continuous time signal over antennas of a base station device. The second values can comprise fewer values than the first values.
