1. A method of wireless communication performed by a base station, comprising:
performing interleaving of parts of a plurality of transport blocks for a broadcast or multicast transmission across a plurality of time intervals,
wherein a size of a transport block of the plurality of transport blocks is scaled by a scaling factor,
wherein particular parts of the transport block are mapped to multiple time intervals of the plurality of time intervals,
wherein the parts of the plurality of transport blocks include the particular parts of the transport block,
wherein a part, of the particular parts of the transport block, corresponds to multiple subsets of coded bits respectively corresponding to codeblocks of the transport block, and
wherein the multiple subsets of coded bits are stored in respective circular buffers corresponding to the codeblocks of the transport block; and
transmitting the interleaved parts in the plurality of time intervals.
