Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable storage mediums for video encoding/decoding. An apparatus includes processing circuitry that determines whether a part of a current block of a current picture in a coded video sequence is outside the current picture. The processing circuitry determines whether one of an allowed binary split indicator, an allowed ternary split indicator, and an allowed quaternary split indicator of the current block is true in response to the part of the current block being outside the current picture. The processing circuitry applies an implicit binary split to the current block in response to none of the allowed binary split indicator, the allowed ternary split indicator, and the allowed quaternary split indicator being true.
