摘要： A method for informing about power information and a base station are disclosed in the present document. The method includes: a base station informing a user equipment of at least one of the following types of power ratio information through signalings: ratio information of transmission power for transmitting a second category of control signaling information to transmission power for transmitting dedicated demodulation pilots; and ratio information of transmission power for transmitting data information to transmission power for transmitting dedicated demodulation pilots in a subframe where data transmission occupies only one slot. In the example of the present document, when the second category of control signalings and the data are sent, different transmission layers and transmission powers can be selected, which solves the problem resulted from an inconsistency of Demodulation Reference Signal (DMRS) powers and avoids a demodulation error.
