Background technique

In the development process of wireless communication technology, how to reduce the energy consumption of base stations has become a hot topic of research.

One way to reduce base station energy consumption is to dynamically switch space units, such as certain antenna units, ports, transceiver chains (TRX chain), beams, panels, etc., but dynamic switches The spatial unit will cause the actual transmitted beams or pilots to change, for example, some beams are turned off or some pilots are turned off, etc.
