BEAM PRECODING MANNER REPORTING METHOD, SCHEDULING METHOD, AND DEVICE

摘要

Embodiments of the present invention provide a beam precoding manner reporting method, a scheduling method, and a device. The reporting method includes: determining, by UE, a used beam precoding manner, where the beam precoding manner is used to indicate a first beam combination usage result, and the first beam combination usage result includes usage manners, which are determined by the UE when the UE uses beams in combination, of the beams, where a beam combination usage manner includes one or two or three of beam selection, beam multiplexing, and beam cooperation according to different total quantities of the beams; and sending, by the UE, the beam precoding manner to a base station, so that the base station schedules the UE based on the beam precoding manner. Technical solutions of the present invention can reduce inter-cell interference in an active antenna system during vertical cell splitting, and increase a system throughput.

1. A beam precoding manner reporting method, comprising:
determining, by a user equipment (UE), a beam precoding manner used by the UE, wherein the beam precoding manner indicates a first beam combination usage result, and the first beam combination usage result comprises usage manners of beams that are determined by the UE when the UE uses beams in combination, wherein: if a total quantity of the beams is 2, a beam combination usage manner comprises one of beam selection, beam multiplexing, and beam cooperation; if the total quantity of the beams is 3, the beam combination usage manner comprises one or two of the beam selection, the beam multiplexing, and the beam cooperation; and, if the total quantity of the beams is greater than or equal to 4, the beam combination usage manner comprises at least one of the beam selection, the beam multiplexing, and the beam cooperation; and sending, by the UE, the beam precoding manner to a base station, so that the base station schedules the UE based on the beam precoding manner, wherein beam selection refers to requiring that at least one beam among the beams that is different from a serving beam cannot serve another UE on a time-frequency resource used by the serving beam; wherein beam multiplexing refers to requiring that at least one beam among the beams that is different from a serving beam serves another UE on a time-frequency resource used by the serving beam; wherein beam cooperation refers to requiring that at least two beams that use a same time-frequency resource among the beams are used as serving beams; and wherein the serving beam refers to a beam that serves the UE among the beams.
