摘要： Provided is a radio base station eNB including a transmission timing decision unit and a system information transmission unit. The transmission timing decision unit decides a transmission radio frame according to an offset Xk from a transmission timing of a first system information SI-1 and a transmission cycle Tk for other system information k and decides a transmission sub-frame in a decided transmission radio frame according to scheduling information contained in the first system information SI-1. The system information transmission unit transmits other system information k in the decided transmission sub-frame. The offset Xk is defined so as to be different for each transmission cycle Tk.

摘要： A base station apparatus includes a classification unit configured to classify user apparatuses based on channel state of a radio link, a DRX (Discontinuous Reception) status memory configured to store information indicating which of multiple groups each of one or more of the user apparatuses conducting DRX belongs to, a determination unit configured to determine which of the groups the user apparatuses classified by the classification unit are to belong to with reference to the information stored in the DRX status memory, and an indication unit configured to indicate the determined groups to the user apparatuses. Each of the groups includes one or more of the user apparatuses activating simultaneously. The determination unit is configured to assign one of the user apparatuses having relatively poor channel state to one of the groups having a smaller number of simultaneously activating user apparatuses.
