PROBLEM TO BE SOLVED: To provide techniques for supporting operation of relay stations.SOLUTION: A bitmap may be sent by a base station and/or a relay station to identify subframes of at least two types in multiple radio frames. The bitmap may indicate whether each subframe covered by the bitmap is of a first type or a second type. UE may use the bitmap to control operation thereof. UE may perform channel estimation or measurement for the subframes of the first type and may skip channel estimation and measurement for the subframes of the second type. A base station may transmit data and/or control information on resources not used by a relay station to transmit a reference signal. This may avoid interference to the reference signal from the relay station, which may improve performance for UE communicating with the relay station. |
