Question: In an MBMS download session, if the 'FEC-redundancy-level' is declared as 40%, what does this imply for an FEC-encoded block of K symbols transmitted over the air?
Option 1: The total symbols broadcast will be exactly K symbols.
Option 2: For every K symbols encoded, only 0.6*K symbols are broadcast.
Option 3: The transmission will include an additional 40 symbols for every K encoded.
Option 4: For an FEC-encoded block of K symbols, a total of 1.4*K symbols will be broadcast over the air.
Explanation: According to the FEC-redundancy-level definition, a 40% redundancy level means that for every K symbols encoded (FEC-encoded block), the actual number of symbols transmitted is increased by 40%, resulting in 1.4*K symbols being broadcast, reflecting additional redundant data added for error correction purposes.
