A method (600) for protecting a data transport block against memory errors and transmission errors includes: attaching (601) a first redundancy section to the data transport block for protecting the data transport block against memory errors and providing the data transport block in a memory buffer; attaching (602) a second redundancy section to the data transport block read from the memory buffer for protecting the data transport block against transmission errors and providing the data transport block for transmission; and invalidating (603) the second redundancy section if an evaluation of the first redundancy section of the data transport block read from the memory buffer indicates a memory error.
