Abstract
A base station may perform interleaving of parts of a plurality of transport blocks for a broadcast or multicast transmission across a plurality of time intervals. A size of a transport block of the plurality of transport blocks may be scaled by a scaling factor. The base station may transmit the interleaved parts in the plurality of time intervals.
Claims28
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.
