Subject: [PATCH wireless-next 1/2] wifi: ieee80211: fix definition of EHT-MCS 15 in MRU
Date: Fri, 13 Mar 2026 14:21:49 +0800 [thread overview]
Message-ID: <20260313062150.3165433-1-shayne.chen@mediatek.com> (raw)
According to the definition in IEEE Std 802.11be-2024, Table 9-417r, each
bit indicates support for the transmission and reception of EHT-MCS 15 in:
- B0: 52+26-tone and 106+26-tone MRUs.
- B1: a 484+242-tone MRU if 80 MHz is supported.
- B2: a 996+484-tone MRU and a 996+484+242-tone MRU if 160 MHz is
supported.
- B3: a 3×996-tone MRU if 320 MHz is supported.
