Embodiment Construction
[0042]In the embodiment of the present invention, the base station side sends at least cell-specific parameters containing EPRE information of common pilots and EPRE related information for users, and sends correction information of different user powers to the terminal side; the cell-specific parameters, for users The EPRE related information and the correction information of different user powers are used to provide the terminal side to detect and recover the received data sent by the base station side; The parameters in the correction information of different user powers allocate the power values of symbols on the resource blocks to be sent, and send the resource blocks.
[0043] see figure 2 As shown, the specific process of implementing downlink power control on the base station side in the embodiment of the present invention is as follows:
[0044] Step 201: the base station side sends cell-specific parameters containing at least EPRE information of the common pilot ...
