PROBLEM TO BE SOLVED: To provide techniques for avoiding interference from a relay station so as to improve performance in wireless communication systems.SOLUTION: A bitmap is sent by a base station and/or a relay station to identify subframes of at least two types in multiple radio frames. For example, the bitmap may indicate whether each subframe covered by the bitmap is of a first type or a second type. User equipment pieces (UE) use the bitmap to control their operation. A UE performs channel estimation or measurement for the subframes of the first type and skips channel estimation and measurement for the subframes of the second type. A base station transmits data and/or control information on resources not used by a relay station to transmit a reference signal. |
