1. A method for inter prediction implemented by a processor of a coding system, wherein the method comprises:
deriving combined linear combination parameters from a first set of linear combination parameters and a second set of linear combination parameters, wherein the first set comprises at least one first parameter, wherein values of the first set are independent of a position of a to-be-predicted sample within a to-be-predicted block, wherein the second set comprises at least one second parameter, wherein values of the second set depend upon the position; and
obtaining a value of the to-be-predicted sample using the combined linear combination parameters and predicted values of at least two samples of different reference blocks of the to-be-predicted block.
