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, and performs measurement on reception of the downlink signal. 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 terminal generates and transmits a radio link failure report including the measurement result in the radio resources as instructed when the radio link failure occurs.

主权项

1. A wireless communication terminal comprising:
a receiver which, in operation, receives control information for generating a report related to a measurement result of a communication cell provided by a wireless communication base station; a controller which, in operation,
monitors a state of a radio link with an own cell, which is a communication cell that is in connection with the wireless communication terminal;performs a measurement on a downlink signal in the communication cell provided by the wireless communication base station; andgenerates a radio link failure report including a measurement result when a radio link failure occurs in the own cell; and a transmitter which, in operation, transmits the radio link failure report, wherein if the control information includes an instruction to restrict measurement to a part of radio resources, after the radio link failure occurs the controller generates the radio link failure report including a measurement result in the part of radio resources.
