Patent Application
20250220572
The present application relates to the field of radio communication, and in particular, to methods and apparatuses for transmission processing, a network device, a terminal, and a storage medium.
Power consumption is one of the main indicators of operating costs for telecommunication operators. According to statistics from operators, the operating costs for power consumption in mobile networks account for approximately 23% of the total operating costs, and the vast majority of power consumption therein comes from radio access networks (RANs), especially from active antenna units (AAUs). The power consumption of a 5th generation mobile communication (5G) network is about 2-3 times that of a 4th generation mobile communication (4G) network. Research on power-saving technologies for 5G network power consumption is urgent.
In recent years, with the proposal of open RAN, an open, intelligent, virtualized, and fully interoperable network has attracted attention of operators. The traditional network power-saving technologies are mostly implemented by equipment manufacturers as a proprietary solution, which cannot be adopted for open RAN. For example, the physical layer equipment is provided by equipment manufacturer A, the high-level equipment is provided by equipment manufacturer B, and the core network device is provided by equipment manufacturer C. A non-standard proprietary implementation cannot be adopted for open RAN, which fails to save power for base stations.
Embodiments of the present application provide methods and apparatuses for transmission processing, a network device, a terminal, and a storage medium, for reducing power consumption of a network device and saving power for the network device.
