<P>PROBLEM TO BE SOLVED: To provide a technique for mitigating interference due to a reference signal, or a technique for mitigating interference to the reference signal, in a heterogeneous network. <P>SOLUTION: Interference due to a first reference signal from a first station (for example, a base station) may be mitigated by canceling the interference at a second station (for example, UE) or by selecting a plurality of different resources for sending a second reference signal by the second station (for example, another base station) to avoid collision with the first reference signal. In another aspect, a relay can transmit in an MBSFN mode in a plurality of subframes in which it listens to a macro base station, and transmit in a regular mode in a plurality of subframes in which it transmits to a plurality of pieces of UE. <P>COPYRIGHT: (C)2013,JPO&INPIT |
