摘要： The embodiments of the present invention provide a power control method and a base station. The method includes: obtaining, by a base station, IN PUCCH (i), where the IN PUCCH (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 P 0_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.

摘要： This application provides an earphone assembly, an earphone case, and a watch. The earphone assembly includes an earphone and the earphone case, the earphone has a first magnetic piece, and the earphone case includes a case body and a lid. The case body is provided with an accommodating slot configured to accommodate the earphone, and the lid is configured to open or close the case body. A second magnetic piece is disposed on the lid, and the second magnetic piece is magnetically attached to the first magnetic piece. When the lid is lifted to open the case body, the earphone moves with the lid and is detached from the accommodating slot. When the lid is closed to close the case body, the earphone is attached to the lid and moves with the lid until the earphone is accommodated in the accommodating slot. According to the earphone assembly provided in this application, the earphone can be easily placed into or taken out from the accommodating slot in the earphone case. This helps improve user experience.

摘要： A data strobe signal DQS position adjustment method and apparatus are disclosed. The method includes: obtaining margin effective widths of all data signals DQs in a transmission bus; determining 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; calculating 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 adjusting a delay line DL of the DQS to the first central position. According to this method, a margin of a setup time and a margin of a hold time in which a DQS samples a data signal at a first central position are maximized, thereby avoiding an error code during data reading and writing, and improving reliability of data read and write operations.

摘要： This application pertains to the field of communications technologies, and provides a method and an apparatus for detecting margins of a data signal and a storage device. A receive end of a data signal may adjust a voltage of a reference power source based on a plurality of reference voltages included in a reference voltage set; adjust, based on a plurality of reference moments included in a reference moment set, a moment of an edge of a data strobe signal transmitted by a transmit end of the data signal; and during the adjustment, for each reference voltage and each reference moment, determine whether a bit error exists in data obtained by decoding the data signal when the voltage of the reference power source is the reference voltage and the moment of the edge of the data strobe signal is the reference moment, to obtain a timing margin of the data signal at each reference voltage and a voltage margin of the data signal at each reference moment. The receive end of the data signal automatically detects the timing margin and voltage margin of the data signal, and detection efficiency and accuracy are relatively high.
