1. An apparatus comprising:
at least one processor; and
at least one memory including computer program code electrically coupled to the at least one processor;
the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
determine whether at least one transport block has been successfully delivered to another apparatus; and
determine whether to use the at least one transport block to scramble at least one subsequent transport block based on whether the at least one transport block has been successfully delivered to the other apparatus;
wherein using the at least one transport block to scramble at least one subsequent transport block comprises:
using the at least one transport block to generate a scrambling sequence; and
using the scrambling sequence to scramble the least one subsequent transport block.
