[PATCH 4/4] Add test cases to support MCS change during Retx

Mon Apr 11 10:45:23 UTC 2016


From: Aravind Sirsikar <arvind.sirsikar at radisys.com>

Add test cases to verify the MCS change functionality.
During MCS upgradation such as MCS6->MCS9, 2 blocks
which were sent separately as MCS6, will be clubbed into
one MCS9 block during retransmission. Same holds good for
MCS5->MCS7 transistion. During MCS reduction such as
MCS9->MCS6,2 blocks which were sent together will be
sent separately during the retransmission case. Same is
verified through the generated log file. Currently
MCS8->MCS6 transition is not supported. The retransmission
MCS is being calculated from Table 8.1.1.2 of TS 44.060.
