Abstract: A voltage regulation apparatus and an overcurrent protection method are disclosed. The voltage regulation apparatus includes a current detection control circuit, a power stage circuit, a voltage input terminal, and a voltage output terminal. The power stage circuit includes at least one transistor. Because a current parameter indicates a load current of the at least one transistor, and a plurality of preset overcurrent protection thresholds are dynamic overcurrent protection thresholds obtained after being preset based on temperature information and the like, after obtaining the current parameter, the current detection control circuit compares the current parameter with the plurality of preset overcurrent protection thresholds, to output a control signal, to implement a limiting operation on the current parameter.

Abstract: This application provides a reference signal generation method in which a terminal device or a network device generates a reference signal by using a pseudo-random sequence initial factor cinit provided in the embodiments of this application. Compared with a solution in the current technology, the reference signal generation method can support a relatively large quantity of reference signal sequences, to better meet the requirements of different 5G scenarios. The reference signal generation method may include obtaining a reference signal sequence based on a pseudo-random sequence initial factor cinit, and mapping the sequence to one or more OFDM symbols. The pseudo-random sequence initial factor cinit is related to a parameter d, d=max(log2(nID,max+1)−10,0) or d=max(log2)(nID,max+1)−12,0), max represents that a larger value is selected from two values, and nID,max represents a maximum value of a reference signal sequence ID.
