a communication unit configured to send measurement information to a communication control device (30),
wherein the measurement information depends on the one or more measurement results, wherein the protection status is one of a first protection status which indicates that a first base station (10) is configured to limit transmission other than a reference signal during the frames, and a second base station (10) is not configured to limit transmission other than a reference signal during the frames, and a protected protection status associated with the one or more of the frames which indicates that both of the
36

first base station and the second base station are configured to limit transmission other than a reference signal during the frames.
9. The communication terminal of claim 8, wherein the configuration information indicates that a same protection status is associated with the one or more frames.
10. The communication terminal of claim 8, wherein the configuration information indicates that the same protection status is the protected protection status, and wherein the measurement information comprises an average of the one or more measurement results.
11. A method comprising:
receiving configuration information from a communication control device,the configuration information indicating that a first protection status is associated with frames, obtaining one or more measurement results indicating signal quality associated with one or more frames, the one or more frames being associated with a same protection status; and
sending measurement information to a communication control device (30), wherein the measurement information depends on the one or more measurement results, wherein the protection status is one of a first protection status which indicates that a first base station (10) is configured to limit transmission other than a reference signal during the frames, and a second base station (10) is not configured to limit transmission other than a reference signal during the frames, and a protected protection status associated with the one or more of the frames which indicates that both of the first base station and the second base station are configured to limit transmission other than a reference signal during the frames.
12. A wireless communication system comprising:
a first base station (10) including a first communication unit;
a second base station (10);
a communication control device (30) including a second communication unit and determination unit; and
a terminal (20) including a measurement unit and a third communication unit, wherein:
37
