Abstract: A controller for data strobe signal (DQS) position adjustment includes, when the controller obtains margin effective widths of all data signals in a transmission bus, it determines a left boundary and a right boundary based on the margin effective widths, where the left boundary is a largest value in minimum values of the margin effective widths of all the DQs, and the right boundary is a smallest value in maximum values of the corresponding margin effective widths when all the DQs are aligned with the left boundary. The controller calculates a first central position based on the left boundary and the right boundary, where the first central position is a center of a smallest margin effective width obtained after all the DQs are aligned during read data training, and adjusts a delay line (DL) of the DQS to the first central position.

Abstract: The embodiments of the present invention provide a power control method and a base station. The method includes: obtaining, by a base station, INPUCCH(i), where the INPUCCH(i) is average interference noise power of a physical uplink control channel (PUCCH) carried by radio resources that are allocated by the base station at a subframe i; and sending, by the base station, a parameter PO—NOMINAL—PUCCH(i) for power control at the subframe i. In the embodiments of the present invention, the base station may send a more accurate parameter to a UE, so that PUCCH transmit power which is at the subframe i and calculated by the UE is more accurate, and network interference caused by increasing the PUCCH transmit power is further reduced.
