WIRELESS COMMUNICATION TERMINAL, WIRELESS COMMUNICATION BASE STATION, WIRELESS COMMUNICATION SYSTEM, AND REPORTING METHOD

摘要

In a wireless communication terminal in a wireless communication system for performing a control not to transmit signals, or to transmit signals with a reduction in a transmission power by a part of radio resources for a downlink signal in a cell provided by a base station, the terminal receives control information in generating a report related to a measurement result of the cell provided by the base station, monitors a state of a radio link with an own cell, performs measurement on reception of the downlink signal, generates a radio link failure report including a measurement result when a radio link failure occurs, and transmits the radio link failure report. If an instruction for restricting the measurement to a part of the radio resources is included in the control information from the base station after the radio link failure occurs, the wireless communication terminal generates a radio link failure report including the measurement result in the radio resources as instructed when the radio link failure occurs. Accordingly, an external device can precisely grasp a state in which the radio link failure occurs in the wireless communication terminal even in an environment in which the ABS is used.
