Title:
BASE STATION, BASE-STATION CONTROL METHOD, AND WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/104088
Kind Code:
A1
Abstract:
An eNB (20) includes an offset calculation unit (220) and a wireless-line control unit (222). If an UL/DL configuration of any UE has been changed, the wireless-channel control unit (222) identifies a first subframe that is a subframe set as a downstream section in the UL/DL configuration prior to the change, and that is changed to an upstream section in the UL/DL configuration after the change. The offset calculation unit (220) provides a first UE in which the UL/DL configuration has been changed with an instruction of an initial value of transmission power in the first subframe. In addition, for a second UE, the offset calculation unit (220) calculates the amount of change in reception quality of the first subframe before and after the UL/DL configuration change. In addition, after the first UE has performed transmission in the first subframe using a transmission power corresponding to the initial value, the offset calculation unit (220), on the basis of the amount of change, controls the transmission power of which an instruction is to be provided to the first UE.
