Abstract
Methods, systems, and devices for wireless communications are described. In some systems, base stations may transmit downlink transmissions in transmission time intervals (TTIs) or short TTIs (sTTIs). The base stations and user equipment (UE) receiving the downlink transmissions may be configured to determine a transport block size, soft channel bit buffer size, or rate matching based on the sTTI. The transport block size may be selected based on a scaling factor associated with signaling overhead or a type, length, or index of sTTI, or based on an sTTI transport block size table. The buffer size may be selected based on scaling or not scaling a buffer size value associated with a TTI. UEs may handle receiving retransmissions of downlink transmissions in different length TTIs, and base stations may select channel quality indicator-to-modulation and coding scheme mappings on an sTTI-by-sTTI basis.
