Abstract
Description
図3は、本発明の実施の形態1に係る端末の構成を示すブロック図である。この図において、系列情報設定部101は、CoMPセット設定部102、サービングセル設定部103、セル選択部104及び系列情報算出部106を備えている。
図6は、本発明の実施の形態2に係る端末の構成を示すブロック図である。図6が図3と異なる点は、CoMPセット設定部102をCoMPセット設定部401に変更し、サービングセル設定部103をCoMPサブセット設定部402に変更し、セル選択部104をセル選択部403に変更した点である。
(CoMPセット内のセル数)=(CoMPサブセットのセル数)+1…(1)
実施の形態2では、CoMPサブセットを構成するセルが、CoMP端末と基地局とのパスロスに基づいて選択されることを前提として説明したが、CoMPサブセットを構成するセルが、各セルのトラフィックを均等にするなど、負荷分散を目的として選択されることも考えられる。そこで、本発明の実施の形態3では、CoMPサブセットを構成するセルが、CoMP端末と基地局とのパスロスに基づいて選択されるか否かにかかわらず、CoMP端末とNon-CoMP端末のDM-RSの符号間干渉をより確実に低減する場合について説明する。
