The SSRC shall be incremented when any short retry count (SRC) associated with any MPDU of type Data is incremented. ... The CW shall take the next value in the series every time an unsuccessful attempt to transmit an MPDU causes either STA retry counter to increment, until the CW reaches the value of aCWmax.'' 42 42 43 '' Excerpt B of Section 9.3.3 of 802.11-2012''43 '''''Excerpt B of Section 9.3.3 of 802.11-2012''''' 44 44 45 45 ''The CW shall be reset to aCWmin after every successful attempt to transmit a frame containing all or part of an MSDU or MMPDU, ...

The SRC for an MPDU of type Data or MMPDU and the SSRC shall be incremented every time transmission of a MAC frame of length less than or equal to dot11RTSThreshold fails for that MPDU of type Data or MMPDU. This SRC and the SSRC shall be reset when a MAC frame of length less than or equal to dot11RTSThreshold succeeds for that MPDU of type Data or MMPDU.''
