    摘要： An object is to appropriately perform transmission power control on a mobile station (UE) when performing “Inter-eNB CA” by using cells under the control of plural radio base stations (eNB). In a mobile communication system according to the present invention, each of plural radio base stations (eNB#1, eNB#2) reduces, upon detecting that the mobile station (UE) is performing transmission at a maximum transmission power (PCMAX,c), by a predetermined amount a transmission power of the mobile station (UE) in a cell (#1/#2A to #2C) under the control thereof and notifies other radio base station (eNB) of the predetermined amount.

    摘要： A terminal according to one aspect of the present disclosure includes: a control section that assumes that a frequency domain orthogonal cover code (FD-OCC) having a sequence length of a number larger than two is applied to a demodulation reference signal mapped to a pair of resource elements the number of which is greater than two and that are being different in frequency; and a transmitting/receiving section that performs transmission processing or reception processing of the demodulation reference signal, based on the FD-OCC. According to one aspect of the present disclosure, even when there are terminals according to different releases, each of the terminals can appropriately perform communication.
