Wireless Terminal Device, Wireless Communication System, and Wireless Terminal Device Controlling Method

摘要

A wireless terminal device determines, based on predetermined information, a transmission power that is a power of a signal to be transmitted to a connected base station. The wireless terminal device includes a connected-base-station distance measuring unit that measures a connected-base-station distance; an adjacent-base-station distance measuring unit that measures an adjacent-base-station distance; a distance comparing unit that compares the connected-base-station distance and the adjacent-base-station distance with each other when accepting information indicating that interference occurs from the adjacent base station; and a transmission-power adjusting unit that lowers a power of a signal to be transmitted to the connected base station below the transmission power when a difference between the connected-base-station distance and the adjacent-base-station distance is equal to or smaller than a predetermined threshold.
