Embodiment Construction

[0022] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.

[0023] The basic model of traditional distributed MIMO system is as follows: figure 1 As shown, the distributed base stations are placed in different geographical locations, and are connected to the main processing unit through optical fibers, that is, part of the wireless channels are replaced by optical fiber channels, which shortens the access distance between the mobile station and the base station, and greatly improves the overall performance. System reliability. At the same time, the separa...

Abstract

The invention discloses a green intelligent distributed MIMO system building method based on directional antennas. The sector-shaped directional antennas with the emission angle of 90 degrees are applied to a distributed MIMO system, a traditional hexagon cellular network mode is broken, a new network scheduling scheme is disclosed, and network signal interference on a base station side can be effectively prevented. The method is in cooperation with a main processing unit to carry out independent sleep and activation scheduling on distributed base stations in the system and the direction antennas in the base stations. The method can intelligently meet different needs of mobile stations in a coverage area, the number of the direction antennas is changed according to change of the needs in an activation state, on the premise that service needs of all the mobile stations are completely met, system power consumption is effectively controlled, and truly green and intelligent communication is achieved.
