1. A method for video decoding comprising:
obtaining video pictures which are partitioned into a plurality of coding units (CUs), at least one of which is further partitioned into two prediction units (PUs);
determining whether a Merge mode with Motion Vector Difference (MMVD) prediction mode and a triangle prediction mode are enabled;
in response to determining that all other merge related modes are signaled as disabled, inferring that the triangle prediction mode is enabled; and
in response to determining that the MMVD prediction mode and the triangle prediction mode are enabled, obtaining Motion Vector Difference (MVD) related syntax elements under the MMVD prediction mode for a triangle PU in a current CU.
