1. A method of video coding, wherein the method comprises:
obtaining block size information of a current block;
determining a partitioning direction based on the block size information;
determining, based on the block size information, a number of sub-partitions to which the current block is to be partitioned in the partitioning direction, wherein the sub-partitions are for intra prediction, wherein each of the sub-partitions comprises 16 samples;
partitioning the current block into sub-partitions for intra prediction, wherein the partitioning direction is based on the block size information, wherein the number of sub-partitions to which the current block is to be partitioned is based on the block size information;
performing, by separate intra prediction of the sub-partitions, the intra prediction of the sub-partitions when a width of each of the sub-partitions is greater than or equal to 4 samples;
performing, by collaborative intra prediction of the sub-partitions, the intra prediction of the current block by combining at least two sub-partitions of the sub-partitions when the at least two sub-partitions have a width less than 4 samples and a combined width of the at least two sub-partitions is greater than or equal to 4 samples; and
coding the sub-partitions.
