Abstract: Provided are a method and device for determining a sequence group and a method and device for determining a cyclic shift. The method includes: determining a symbol index of a first specified orthogonal frequency division multiplexing (OFDM) symbol in a scheduling unit; and determining a sequence group or cyclic shift used by a channel or a signal according to the symbol index.

Abstract: The present invention relates to a method of preventing misoperation about a relay protection device in a smart substation. Reversely operating CPU operation results of two operation records about the relay protection device, in order to form corresponding disassembler codes. According to disassembler codes, calculating similarity of the CPU operation results of the two operation records about the relay protection device by a structured method. Judging whether the similarity is greater than a set threshold or not. If the similarity is greater than the set threshold, the CPU operation results of the two operation records about the relay protection device to be the same, otherwise, the CPU operation results of the two operation records about the relay protection device are judged to be different. The present invention avoids the misoperations of the relay protection device on operation.
