Radio communication device

Abstract

PROBLEM TO BE SOLVED: To provide a radio communication device capable of obtaining high throughput.SOLUTION: An embodiment of the disclosure includes an propagation path information acquisition unit and a scheduling unit. The propagation path information acquisition unit acquires an interference power value indicating an interference state of a propagation path from each of a plurality of extended radio base stations including one or more antennas. The scheduling unit divides cells formed by the respective plurality of extended radio base stations into multiple groups according to the interference power value. The scheduling unit determines the time difference between first timing to perform scheduling of first period which allows communication among cells belonging to a first group and second timing to perform scheduling of second period which allows communication among cells belonging to a second group, to be longer than a third period including a period wherein the extended radio base stations forming cells belonging to the second group acquire interference power values.

Description

technical field [0001] The present invention relates to wireless communications. Background technique [0002] In a cellular system, there is a distributed base station in which a radio unit and a baseband unit are separated, and a plurality of radio units are connected by a single baseband unit. For example, in scheduling (user selection and channel assignment) of a plurality of cells of an initial distributed base station, it is assumed that scheduling of a plurality of conventional integrated base stations is performed simultaneously. That is, scheduling of a plurality of adjacent cells is performed at the same timing. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2009-206945 [0004] However, if the channel information that can be used in the current cellular system is used to perform scheduling between adjacent cells simultaneously, when the timing of the implementation is simultaneous in a plurality of adjacent cells, it becomes a mutual self-constraint c...

Problems solved by technology

[0004] However, if the channel information that can be used in the current cellular system is used to perform scheduling between adjacent cells simultaneously, when the timing of the implementation is simultaneous in a plurality of adjacent cells, it becomes a mutual self-constraint channel allocation, which occurs Lots of wasted idle time with no channel assigned to any cell

In addition, since user terminals that interfere with each other may be simultaneously selected in adjacent cells, the scheduling result is low in frequency utilization efficiency.
