Document Type and Number:
Japanese Patent JP6670834
Kind Code:
B2
Abstract:
A base station according to one embodiment performs superposition transmission that is a scheme for performing MBMS transmission and PDSCH transmission by using the same time-frequency resource. The base station performs the processes of; transmitting PDSCH data to a radio terminal by the PDSCH transmission and transmitting a demodulation reference signal for demodulating the PDSCH data; and transmitting, to the radio terminal, information indicating a ratio or an offset of a transmission power of the demodulation reference signal with respect to a transmission power of the PDSCH data.
