A method and an apparatus for transmitting error-tolerant data is
disclosed employing the ARQ technique, wherein the retransmission of
erroneous data is performed up to the point where the remaining amount of
errors is acceptable (for instance because the erorrs will not be
perceived by the recipient of the information, which can be a person or a
higher level protocol with additional error correction capabilities). The
number of data blocks (RLC) detected as erroneous is employed to define a
reliability measure (RM) and a request for retransmission of the
erroneous data blocks is performed until a desired reliability threshold
(RT) is reached. An additional threshold with a higher value than the
first one can be employed to request for optional retransmission when the
reliability measure (RM) is between the first and the second threshold.
The retransmission will be performed only if further conditions such as
channel availability are met.
