1. A method of generating a coded video bitstream using at least one processor, the method comprising:
receiving video data;
encoding a current layer of the video data without horizontal wrap-around motion compensation;
setting a first flag pps_ref_wraparound_enabled_flag, wherein the first flag pps_ref_wraparound_enabled_flag being equal to 1 specifies that the horizontal wrap-around motion compensation is enabled for pictures referring to a picture parameter set in a coded video stream;
determining whether a reference picture is not scaled based on whether refPicWidthInLumaSamples is equal to pic_width_in_luma_samples of a current picture;
in response to the reference picture being not scaled, setting a second flag refWraparoundEnabledFlag to be equal to a value of the first flag pps_ref_wraparound_enabled_flag; and
generating a coded video bitstream based on the encoded current layer, the picture parameter set, the first flag pps_ref_wraparound_enabled_flag, and the second flag refWraparoundEnabledFlag.
