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 base station apparatus comprising:
a transmitting section configured to transmit, to a terminal, control information indicating subframes, for which a channel quality is measured; and
a receiving section configured to receive information indicating the channel quality measured by the terminal for the subframes indicated by said control information,
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 indicated by said control information.
2. The base station apparatus according to claim 1 , wherein the other cell is a neighbour cell.
3. The base station apparatus according to claim 1 , wherein the other cell causes interference.
4. The base station apparatus according to claim 1 , wherein a subframe other than a MBSFN (Multicast/Broadcast over Single Frequency Network) subframe is included in the subframes indicated by said control information.
5. The base station apparatus according to claim 1 , wherein said control information indicates the second subframe as being bit mapped.
6. The base station apparatus according to claim 1 , wherein said control information indicates the second subframe as being patterned.
7. The base station apparatus according to claim 1 , wherein the subframes indicated by said control information are different depending on a cell.
8. The base station apparatus according to claim 1 , wherein the receiving section receives the information indicating the channel quality that the terminal measures based on said control information for a subframe, in which the other cell causes interference.
9. The base station apparatus according to claim 1 , wherein the receiving section receives information indicating a reception power measured by the terminal as the channel quality.
10. The base station apparatus according to claim 1 , wherein the receiving section receives information indicating a reception quality measured by the terminal as the channel quality.
11. A communication method comprising:
transmitting, to a terminal, control information indicating subframes, for which a channel quality is measured; and
receiving information indicating the channel quality measured by the terminal for the subframes indicated by said control information,
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 indicated by said control information.
12. The method according to claim 11 , wherein the other cell is a neighbour cell.
13. The method according to claim 11 , wherein the other cell causes interference.
14. The method according to claim 11 , wherein a subframe other than a MBSFN (Multicast/Broadcast over Single Frequency Network) subframe is included in the subframes indicated by said control information.
15. The method according to claim 11 , wherein said control information indicates the second subframe as being bit mapped.
16. The method according to claim 11 , wherein said control information indicates the second subframe as being patterned.
17. The method according to claim 11 , wherein the subframes indicated by said control information are different depending on a cell.
18. The method according to claim 11 , wherein the receiving step receives the information indicating the channel quality that the terminal measures based on said control information for a subframe, in which the other cell causes interference.
19. The method according to claim 11 , wherein the receiving step receives information indicating a reception power measured by the terminal as the channel quality.
20. The method according to claim 11 , wherein the receiving step receives information indicating a reception quality measured by the terminal as the channel quality.
