1. A method for video decoding in a decoder, comprising:
decoding, by a processor, prediction information for a block in an I slice from a coded video bitstream;
setting, by the processor, a current mode type parameter for the block to be MODE_TYPE_INTRA when at least a width or height of the block being greater than 64;
determining, by the processor, whether a skip mode flag is signaled for the block in the I slice in the coded video bitstream based on at least a width or height of the block being greater than 64 and the current mode type parameter wherein the skip mode flag indicates whether a skip mode is applied to the block, the skip mode flag is determined to be signaled in response to neither the width nor the height of the block being greater than 64 and the current mode type parameter not being MODE_TYPE_INTRA, and the skip mode flag is determined not to be signaled in response to at least one of the width or the height of the block being greater than 64 or the current mode type parameter being MODE_TYPE_INTRA;
in response to a determination that the skip mode flag is not signaled in the coded video bitstream, inferring the skip mode flag as indicating that the skip mode is not applied to the block; and
reconstructing, by the processor, the block at least partially based on the skip mode flag.
