Abstract: This application provides a method for detecting margins of a data signal. A receive end of a data signal may adjust a voltage of a reference power source; 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.

Abstract: The embodiments of the present invention provide a method, an apparatus and a system for service establishment for a multi-mode user equipment. In an embodiments of the present invention, a centralized control entity (Controller) may obtain the base station information of the respective base stations in the multi-RAT network in real time and select proper RAT base station information in accordance with service demand of the user equipment, so as to initiate bearer establishment for the service. Compared with the prior art which only aims at a particular service and handover can only be performed in particular RAT networks, the present solution does not has particular limitation on a service, and moreover, a proper RAT network may be selected from multiple RAT networks more flexibly for each service without increasing power consumption of the user equipment.

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.
