WIRELESS COMMUNICATION DEVICE AND WIRELESS COMMUNICATION METHOD

摘要

The disclosed device enables the transmission of a reference signal such as a CSI-RS while maintaining the power conserving effect when performing inter-cell coordination transmission/reception and the like in a plurality of cells. In order to achieve inter-cell coordination transmission/reception, a CSI-RS used for estimating the state of a spatial propagation path of a communication line is generated by a CSI-RS generation unit, and this CSI-RS is disposed in a predetermined subframe by a disposition unit and is transmitted. At this time, in a frame that has ten subframes #0 through #9, the CSI-RS is disposed and transmitted in subframes #4 and #9, which are subframes that exclude subframes #0 and #5 that cannot transmit a CSI-RS and are subframes aside from the subframes that be MBSFN subframes when performing intermittent transmission (extended cell DTX) for increasing power conservation.
