STRUCT IEEE80211_UHR_P_EDCA_INFO(9)

✨ NAME ✨

struct ieee80211_uhr_p_edca_info — P-EDCA operation information 🫶 (yes bestie, this is a page straight out of the Kernel API Manual, and we're gonna get into it)

🎀 SYNOPSIS 🎀

struct ieee80211_uhr_p_edca_info {
    u8 p_edca_ec;
    __le16 params;
 };

🌸 MEMBERS 🌸

• p_edca_ec — the P-EDCA ECWmin and ECWmax, together, iconically. These fields are literally telling you the CWmin and CWmax values that a P-EDCA STA uses during P-EDCA contention. no cap 💅
• params — a whole little bundle: AIFSN, CW DS, PSRC threshold, and QSRC threshold. Let's break it down:
  • The AIFSN field indicates the AIFSN value used by a P-EDCA STA during P-EDCA contention. ✨
  • The CW DS field indicates the value used for randomization of the transmission slot of the DS-CTS frame. The value 3 is reserved. 🙈 The value 0 indicates that randomization is not enabled.
  • The P-EDCA PSRC threshold field indicates the maximum number of allowed consecutive DS-CTS transmissions. The value 0 and values greater than 4 are reserved. 💀 (so like… don't.)
  • The P-EDCA QSRC threshold field indicates the value of the QSRC[AC_VO] counter required to start P-EDCA contention. The value 0 is reserved. ⭐

🦋 DESCRIPTION 🦋

okay so this structure is the "P-EDCA Operation Parameters field" of "UHR Operation Element" fields, exactly as described in P802.11bn_D1.3 subclause 9.4.2.353. See Figure 9-aa5. 📖
