1. A method for video decoding in a decoder, comprising: before parsing a flag of a specific inter picture prediction mode indicating whether the specific inter picture prediction mode is used for coding a current block from a coded video bitstream and checking an inferable condition for another flag that is one of a regular flag of a regular merge/skip mode, a merge with motion vector difference (MMVD) flag of an MMVD mode, a combined intra inter prediction (CIIP) flag of a CIIP mode, or a triangle flag of a triangle partition mode, checking, based on size information of the current block, whether the flag is inferable or whether the flag is signaled, whether the regular merge/skip mode, the MMVD mode, the CIIP mode, or the triangle partition mode is allowed being determined based on at least one of a sequence parameter set (SPS), a picture parameter set (PPS), a slice header, tile information, and tile group information;
inferring, by a processor, the flag without parsing the flag from the coded video bitstream when the flag is inferable;
parsing, by the processor, the flag from the coded video bitstream when the flag is signaled in the coded video bitstream; and
reconstructing, by the processor, the current block according to the specific inter picture prediction mode when the flag is indicative of an application of the specific inter picture prediction mode on the current block, wherein
when the size information of the current block indicates that a width or a height of the current block is not greater than or equal to 8, the checking indicates that the flag is inferable.
