Radio communication device

Abstract

The invention provides a radio communication device higher throughput per hour, which comprises a transmission path information acquiring unit and a scheduling unit. The transmission path information acquiring unit acquires interference power value from more than one antenna remote base station. The scheduling unit divides the plurality of antenna remote base stations into several groups according to the acquired interference power value. The time difference between a first timing scheduled during a first period and a second timing scheduled during a second period is determined to be above a third period. The first period is a communication period within the subdistrict of a first group, while the second period is a communication period within the subdistrict of a second group. The third period comprises a period obtaining the interference power value from the remote base station of the subdistrict of the second group.

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.
