    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.

    摘要： A method for instructing CSI feedback signaling configuration and base station are provided, the method comprising: a base station side notifies a terminal side, via the first higher layer signaling of a UE-Specific, a CSI-RS resource for measuring CSI, the CSI-RS resource comprising at least one of: the time frequency position of the CSI-RS resource in a subframe, the aerial port number configuration of the CSI-RS resource, a period and a subframe offset of the CSI-RS resource, the sequence identifier of the CSI-RS resource, and the power control information of the CSI-RS resource; the base station side instructs the terminal side to feed back the CSI corresponding to the CSI-RS resource. In the present invention, the base station side flexibly configures the terminal side to feed back various kinds of CSI information, thus enabling the base station side to flexibly and dynamically acquire the CSI, and in turn realizing precise link self-adaption and data transmission, and reducing the uplink feedback overhead and measurement complexity of the terminal side.

    摘要： A method and device for sending an aggregated CQI are provided by the disclosure. The method includes a terminal side receiving CSI-RS configuration information and/or interference measurement information sent from a base station side, the terminal side determining a sending sequence of aggregated CQI of each aggregated CSI-RS configuration resource and/or interference measurement resource according to a receiving sequence of the CSI-RS configuration information and/or interference measurement information, wherein each aggregated CSI-RS configuration resource and/or interference measurement resource is aggregated of at least one configuration CSI-RS configuration resource and/or interference measurement resource corresponding to the CSI-RS configuration information and/or interference measurement information, the terminal side sending the aggregated CQI to the base station according to the sending sequence. The disclosure resolves the problem in related art that the base station side cannot acquire the channel state of the terminal side accurately due to the fact that the base station side cannot acquire the CSI-RS configuration resource and/or interference measurement resource fed back by the terminal side corresponding to the aggregated CQI, thereby the interference between cells is reduced, and the throughput of system is improved.
