Abstract: Methods and apparatus, including computer program products, are provided for multi-slot transport block size determination. In some example embodiments, there may be provided a method that includes calculating a number of resource elements allocated within a resource element set based at least on an overhead value used for transport block size determination of a transport block that is transmitted over multiple slots; calculating a total number of resource elements, allocated for a physical uplink shared channel or a physical downlink shared channel, covering multiple slots for the transport block size determination based at least on the calculated number of resource elements allocated within the resource element set; and transmitting or receiving the transport block over multiple slots.

Abstract: Where large transport blocks are rate-matched and transmitted on each PUSCH segment using different redundancy versions (RVs), RV cycling with a small number of PUSCH segments might not cover the whole codeword, and/or rate-matching a large TBS across many PUSCH segments into the resource of a single PUSCH segment may lead to an effective coding rate of the self-decodable redundancy versions that is too high. To avoid these issues, the starting position of one or more RVs may be shifted by setting the starting position of a current RV to be the same as an ending position of a previous position, or by scaling the starting position by a value. Alternatively, these issues may be avoided by setting a new starting position for an RV based on the gap from the end of a previous RV to the start of a current RV.
