WIRELESS COMMUNICATION TERMINAL AND COMMUNICATION METHOD FOR MEASURING A CHANNEL QUALITY INDICATOR (CQI)

摘要

To measure the channel quality of the own cell accurately in a condition where there is no interference from a neighbor cell. A wireless communication terminal according to the invention is a wireless communication terminal to be connected to a base station for transmitting and receiving data to/from the base station, the wireless communication terminal including: a receiver that receives a signal which includes control information provided for measuring a channel quality of own cell from the base station; an extractor that extracts the control information from the signal received by the receiver; a measurement section that measures, on the basis of the control information, the channel quality of the own cell in a domain where a neighbor cell does not transmit a signal; and a transmitter that transmits a measurement result of the channel quality of the own cell measured by the measurement section, to the base station.

主权项

1. A communication apparatus comprising:
a transmitter, which, in operation, transmits, to a terminal, information indicating subframes that include a subframe in which no downlink data is transmitted by another cell, and transmits, to the terminal, a reference signal on the subframe in which no downlink data is transmitted by the other cell; and a receiver, which, in operation, receives a Channel Quality Indicator (CQI), which the terminal measures using the reference signal, the CQI being measured for a subframe, in which the other cell causes no interference to a cell to which the terminal belongs, based on said information.
