Reply To: la/ir/bler mode in eric


oh ok , link adaptation makes more sense than location area ๐Ÿ™‚

sheldon : IR is not available for GPRS

IR is actually retransmitting the same piece of information, with the same coding scheme (MCS) but a different puncturing scheme (PS1, PS2 or PS3).
Some exception can be done within MCS of same family : retransmission of MCS9 block can be done over 2 MCS6 blocks with different puncturing schemes. That’s IR with LA. That is an exception though, which tends to confuse many people (me included ! ๐Ÿ™‚ )


i’m ok for discussing fundamentals ๐Ÿ™‚
I really didn’t understand your first question. Now it is clear. I think that LA/IR/BLER is a “word” you see in Ericsson documents ? In alcatel we never use these acronyms next to each other…
