Claim 7:
8. A coding apparatus comprising:
a memory configured to store instructions; and
a processor coupled to the memory and configured to execute the instructions that cause the coding apparatus to be configured to:
obtain first reference samples of a reference block, wherein at least one of the first reference samples is based on an integer part of a fractional motion vector (MV), and wherein at least one of the third reference samples is obtained using one of:

(Imvx=(mvx>>mvp)<<mvp,Imvy=(mvy>>mvp)<<mvp);

(Imvx=(mvx>>mvp)<<mvp,Imvy=mvy); or

(Imvx=mvx,Imvy=(mvy>>mvp)<<mvp),

wherein (Imvx, Imvy) represents an MV of one of the third reference samples, wherein (mvx, mvy) is the fractional MV, and wherein mvp is a constant;

obtain second reference samples of a current block from available top reference samples (Top[i]) in reference lines, wherein i=0 . . . W, and wherein W represents a width of the current block;
estimate local illumination compensation (LIC) parameters using the second reference samples and the first reference samples; and
obtain inter prediction of the current block according to the LIC parameters.
