Aspects of the disclosure include methods, apparatuses, and non-transitory computer-readable storage mediums for video encoding/decoding. An apparatus includes processing circuitry that decodes prediction information of a current block in a coded video bitstream. The prediction information comprises at least one reference picture index used in low delay inter bi-prediction for the current block. Each of the at least one reference picture index has a same value. The processing circuitry determines a first reference picture in a first reference picture list and a second reference picture in a second reference picture list based on the at least one reference picture index. The current block is coded using the low delay inter bi-prediction. The first reference picture list is identical to the second reference picture list. The first reference picture is identical to the second reference picture. The processing circuitry reconstructs the current block based on the first and second reference pictures.
