Problems solved by technology

Since one beam in one cell is split into multiple beams in multiple cells, and the same physical resources are reused between multiple beams, there is interference between multiple beams, which is a direct result of cell splitting. The interference intensity of the cell will increase. If the beam design for cell splitting is not optimized, the interference problem will even seriously reduce the throughput of the system.

Abstract

Embodiments of the present invention provide a method for reporting a beam precoding mode, a scheduling method, and a device. The reporting method includes: the UE determines the beam precoding method used, and the beam precoding method is used to indicate the first beam combination use result, and the first beam combination use result includes the use method of each beam determined by the UE when the beam combination is used, wherein , according to the total number of beams, the beam combination method includes one, two or three of beam selection, beam multiplexing and beam cooperation; the UE sends the beam precoding mode to the base station so that the base station The precoding mode schedules the UE. The technical scheme of the invention can reduce the interference between cells vertically split to medium and small cells in an active antenna system, and improve the throughput of the system.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a beam precoding method reporting method, scheduling method and equipment. Background technique [0002] In mobile communication, the signal from the base station to the user equipment is sent through the physical antenna on the base station side. For macro network deployment, in order to improve system capacity and increase base station coverage, general wireless communication systems generally use directional antenna technology instead of omnidirectional antenna technology for macro network base station antennas. The graph describing the variation of the gain of a directional antenna as the horizontal or vertical direction changes is called a gain pattern. Base station antennas can be divided into passive antennas and active antennas. For the active antenna, its gain pattern can be changed in real time, that is to say, the high gain direction of the acti...
