Abstract

Network Energy Saving (NES) techniques are becoming increasingly important for the radio access networks towards 6G, considering the high demand for beamforming due to higher frequency bands in 6G. Indicating even higher energy consumption as motivation to do more in 6G for NES. While Cell Discontinuous Transmission (DTX) has been standardized to reduce energy consumption, its effectiveness is constrained by the time-domain occupancy of mandatory common signaling (e.g. SIB1), particularly when multiple beams are used. In this paper, we investigate the impact of beamforming on cell DTX performance and analyze how periodical transmission of common signals limits energy savings. To address this limitation, we evaluated a standalone on-demand System Information Block (SIB1) mechanism, in which system information is transmitted only upon explicit user equipment request. Simulation results show that while beamforming improves interference, reducing periodic SIB1 transmission is necessary to decrease time-domain occupancy. In a standalone configuration, on-demand SIB1 reduces energy consumption and delay in beamforming deployments especially related to future 6G deployments using frequency bands of FR3 (7.125 GHz to 24.25 GHz).
