摘要： The present invention provides two methods for configuring transmit power of sounding reference signal (SRS), a network device and a UE. One of the methods includes: with a network device, determining SRS transmit power parameters according to power level of signal previously sent from a UE received by each cell to be detected and/or information of cells to be detected by the UE, and sending the SRS transmit power parameters to the UE. The present invention can have an overall consideration on path losses of multiple cells to be detected when calculating the SRS transmit power. Therefore, the power of the cell having poor channel quality for receiving SRS can be guaranteed, in order to ensure the accuracy of channel estimation.

摘要： Disclosed are a method and device for R-PDCCH transmission in the scenario of carrier aggregation. By way of applying the technical solution of the embodiments of the present invention, multi-carrier aggregation transmission is supported between the relay node and the base station. The base station sends a component carrier carrying the R-PDCCH to the relay node and schedules the resources in each component carrier by way of the R-PDCCH carried in the component carrier. Thus what is achieved is that the base station communicates with the relay node by way of a plurality of aggregated component carriers, enabling the link transmission resources between the base station and the relay node to support multi-carrier PDCCH scheduling, improving the transmitting capacity of the link between the base station and the relay node, and improving the system performance.
