| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a technique capable of determining a band of a physical control channel set to each user device depending on a congestion state of a band for physical control channels.SOLUTION: A base station in a radio communication system that supports physical control channels transmitted in a narrow band and includes a user device and the base station includes: a selection unit for selecting a band for a physical control channel allocated to the user device by using a selection criterion based on a congestion level of each of bands for a plurality of physical control channels in the bands for the plurality of physical control channels preset in a system band; and a notification unit for notifying the user device of the band for the physical control channel selected by the selection unit.SELECTED DRAWING: Figure 3
【課題】物理制御チャネル用の帯域の混雑状況に応じて、各ユーザ装置に設定する物理制御チャネルの帯域を決定することが可能な技術を提供すること。【解決手段】狭帯域で送信される物理制御チャネルをサポートし、ユーザ装置と基地局とを有する無線通信システムにおける基地局であって、システム帯域内に予め設定される複数の物理制御チャネル用帯域のうち、前記複数の物理制御チャネル用帯域の各々における混雑度に基づく選択基準を用いて、前記ユーザ装置に割当てる物理制御チャネル用帯域を選択する選択部と、前記選択部で選択された物理制御チャネル用帯域を前記ユーザ装置に通知する通知部と、を有する基地局を提供する。【選択図】図３ |
