Abstract
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.

Claim
1. A communication apparatus communicating with a terminal that receives signals from a first cell of the communication apparatus to which the terminal belongs and from a second cell comprising:
a transmitter, which, in operation, transmits, to the terminal, information indicating subframes that include a subframe in which no downlink data is transmitted by the second cell, and transmits, to the terminal, a reference signal on the subframe in which no downlink data is transmitted by the second 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 second cell causes no interference to the first cell to which the terminal belongs, based on said information.
2. The communication apparatus according to claim 1, wherein the second cell is neighbour cell to the first cell to which the terminal belongs.
3. The communication apparatus according to claim 1, wherein the second cell causes interference to the first cell to which the terminal belongs.
4. The communication apparatus according to claim 1, wherein the subframe is a Multicast/Broadcast over Single Frequency Network (MBSFN) subframe.
5. The communication apparatus according to claim 1, wherein the subframes indicated by said information are different depending on a cell.
6. The communication apparatus according to claim 1, wherein the transmitter, in operation, transmits the reference signal mapped on or after the third symbol in a subframe.
7. The communication apparatus according to claim 1, wherein the transmitter, in operation, transmits the reference signal mapped on the seventh symbol in a subframe.
8. A communication method for communicating with a terminal that receives signals from a first cell to which the terminal belongs and from a second cell comprising:
transmitting, to the terminal, information indicating subframes that include a subframe in which no downlink data is transmitted by the second cell, and transmits, to the terminal, a reference signal on the subframe in which no downlink data is transmitted by the second cell; and
receiving a Channel Quality Indicator (CQI), which the terminal measures using the reference signal, the CQI being measured for a subframe, in which the second cell causes no interference to the first cell to which the terminal belongs, based on said information.
9. The communication method according to claim 8, wherein the second cell is neighbour cell to the first cell to which the terminal belongs.
10. The communication method according to claim 8, wherein the second cell causes interference to the first cell to which the terminal belongs.
11. The communication method according to claim 8, wherein the subframe is a Multicast/Broadcast over Single Frequency Network (MBSFN) subframe.
12. The communication method according to claim 8, wherein the subframes indicated by said information are different depending on a cell.
13. The communication method according to claim 8, wherein the transmitting includes transmitting of the reference signal mapped on or after the third symbol in a subframe.
14. The communication method according to claim 8, wherein the transmitting includes transmitting of the reference signal mapped on the seventh symbol in a subframe.
