Mobile communication system

摘要

A mobile communication system includes a plurality of eNBs that perform radio communication with an UE and an MCE that controls the eNBs. The MCE indicates an MBSFN subframe (MCE) serving as radio resources that transmit a reference signal for power measurement to the UE less frequently than normal to the eNB, the eNB, in addition to the MBSFN subframe (MCE) indicated by the MCE, designates the MBSFN subframe (eNB) serving as the radio resources that transmit a reference signal to the UE less frequently than normal, and in the MBSFN subframe (MCE) and the MBSFN subframe (eNB) the reference signal is transmitted to the UE. In this manner, the reference signal for measuring a power can be transmitted less frequently than normal, and a power consumption of the infrastructure can be reduced.
