Maximum transport block sizes and span for a transport block in a non-terrestrial network
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a report of a maximum transport block size supported by the UE for if hybrid automatic repeat request (HARQ) feedback is enabled and a maximum transport block size for is HARQ is disabled. The UE may receive, based at least in part on transmitting the report, one or more transport blocks that have a transport block size that does not exceed the maximum transport block sizes supported by the UE. In some aspects, the UE may receive an indication of a length of a span for receiving a set of bits from channel encoder output for a transport block or a redundancy version of a transport block. Numerous other aspects are provided.
