Zusammenfassung:PROBLEM TO BE SOLVED: To select a suitable SCell when performing carrier aggregation with the use of an SCell using an unlicensed band.SOLUTION: A communication method for performing carrier aggregation with the use of a PCell using a licensed band and an SCell using an unlicensed band includes: an estimation step of estimating difference between communication quality between a primary base station 1 and a communication device 3 and communication quality between a secondary base station 2 and the communication device 3 for each of a plurality of secondary base stations 2; and a determination step of determining a secondary base station 2 which performs carrier aggregation among the plurality of secondary base stations 2 on the basis of the difference estimated for each of the secondary base stations 2.SELECTED DRAWING: Figure 2 【課題】アンライセンスバンドのSCellを用いてキャリアアグリゲーションする際に、好適なSCellを選択すること。【解決手段】ライセンスバンドのPCell及びアンライセンスバンドのSCellを用いてキャリアアグリゲーションを行う通信方法であって、複数の副基地局2の夫々について、主基地局1及び通信装置3の間の通信品質と、副基地局2及び通信装置3の間の通信品質との差分を推定する推定ステップと、副基地局2の夫々について推定した差分に基づいて、複数の副基地局2の中からキャリアアグリゲーションを行う副基地局2を決定する決定ステップと、を含む通信方法。【選択図】図2
