1. A method performed by a communication device, the method comprising:
identifying a long transmission time interval (TTI) transport block size from a set of long TTI transport block sizes used for transport block transmission within a long TTI; and
determining a short TTI transport block size, used for transport block transmission within a short TTI, by downscaling the long TTI transport block size based on a relation between a number of symbols in the short TTI and a number of symbols in the long TTI that is greater than the number of symbols in the short TTI;
wherein the short TTI transport block size is selected from a set comprising the long TTI transport block sizes and an additional transport block size.
