<1.1.システムの全体的な構成>
図1は、本開示の一実施形態に係る通信システムの概要を説明するための説明図である。
セルラーシステムによる周波数2次利用の実施において、以下の懸念がある
無線通信装置をTDDで運用することが想定される。LTEの場合、アップリンク及びダウンリンクの組み合わせの異なる無線フレーム構成が規定されており、干渉低減のために、無線通信装置間で同一の組み合わせを設定することが必要になる。また、時間同期を取る必要もある。
セルラーシステムによる周波数2次利用時の多数の無線通信装置の運用パラメータの変更に伴う運用コスト低減のためにSONを導入することが考えられる。SONにおいては、無線通信装置間の干渉制御等に利用されるインタフェース(e.g. LTE X2インタフェース)構築のために無線通信装置間でシグナリングが実施される。シグナリング実施のためには、どの無線通信装置が近傍に存在するのか知る必要があるが、周波数2次利用シナリオにおいては、運用周波数の変更に伴い、近傍として考慮すべき無線通信装置が動的に変化しうる。

以下では、図5を参照して、無線通信装置の構成例を説明する。
