1. A decoder configured to decode a bitstream signaling one of supported partitioning patterns for a current block of a picture, the decoder being configured to:
if the signaled one of the supported partitioning patterns specifies a subdivision of the current block into two sub-blocks,
remove, for a sub-block except a first sub-block of the sub-blocks in a coding order, from a set of coding parameter candidates for the respective sub-block, a coding parameter candidate associated with a candidate block, wherein the candidate block, when merged with the respective sub-block, results in one of the supported partitioning patterns,
wherein the decoder is configured to:
determine coding parameter candidates for a current sub-block of the sub-blocks,
check whether a total number of determined coding parameter candidates is equal to a predetermined number of coding parameter candidates needed to complete the set of coding parameter candidates for the current sub-block, and
based on an indication from the check that the total number of determined coding parameter candidates is less than the predetermined number of coding parameter candidates, provide one or more ancillary coding parameter candidates to the set of coding parameter candidates to complete the set.
