Radio communication terminal and radio communication method
Provided is a radio communication terminal which is capable of measuring quality in communication with a handover destination with high accuracy. The radio communication terminal is capable of communicating with a base station or a relay node, and includes: a receiver which receives control information including information relating to measurement of measuring quality of a neighbor cell; an extractor which extracts information on a subframe where the measurement should be performed, which is a subframe where only transmission of a signal from the relay node connected to the base station is performed, from the information relating to the measurement; a measurement section which performs the measurement, on a subframe basis, based on the extracted information on the subframe where the measurement should be performed: and a transmitter which transmits a result, of the measurement to the base station or the relay node.
1. A terminal apparatus comprising:
a receiving section configured to receive control information indicating subframes, for which a channel quality is measured; and
a measuring section configured to measure the channel quality for the subframes that said control information indicates,
wherein, out of subframes including a first subframe with no transmission of data by another cell and a second subframe with transmission of data by the other cell, the second subframe is included in the subframes that said control information indicates.
2. The terminal apparatus according to claim 1 , wherein the other cell is neighbor cell.
3. The terminal apparatus according to claim 1 , wherein the other cell causes interference.
4. The terminal apparatus according to claim 1 , wherein a subframe other than a MBSFN (Multicast/Broadcast over Single Frequency Network) subframe is included in the subframes that said control information indicates.
5. The terminal apparatus according to claim 1 , wherein said control information indicates the second subframe, out of subframes including the first subframe with no transmission of data by the other cell and the second subframe with transmission of data by the other cell, as being bit mapped.
6. The terminal apparatus according to claim 1 , wherein said control information indicates the second subframe, out of subframes including the first subframe with no transmission of data by the other cell and the second subframe with transmission of data by the other cell, as being patterned.
7. The terminal apparatus according to claim 1 , wherein the subframes that said control information indicates are different depending on a cell.
8. The terminal apparatus according to claim 1 , wherein the measuring section measures the channel quality for a subframe, in which the other cell causes an interference, based on said control information.
9. The terminal apparatus according to claim 1 , wherein the measuring section measures a reception power as the channel quality.
10. The terminal apparatus according to claim 1 , wherein the measuring section measures a reception quality as the channel quality.
11. A communication method comprising:
receiving control information indicating subframes, for which a channel quality is measured; and
measuring the channel quality for the subframes that said control information indicates,
wherein, out of subframes including a first subframe with no transmission of data by another cell and a second subframe with transmission of data by the other cell, the second subframe is included in the subframes that said control information indicates.
