IEEE 802.11-23/2015r0 A-Control Field Expansion Proposal
Explore the proposal for A-Control field expansion in IEEE 802.11-23/2015r0 standard, introducing a new approach using Retry subfield to indicate A-Control Expansion field. This innovative solution aims to enhance efficiency and reduce complexity in wireless communication protocols. Learn about the rationale behind this proposal and the benefits it brings to future implementations.

Nov 2023 Doc.: IEEE 802.11-23/2015r0 HT Control field expansion Date: 2023-11-10 Authors: Name Affiliations Address Phone email Xiangxin Gu Spreadtrum Xiangxin.gu@unisoc.com Yingqiao Quan Spreadtrum Submission Slide 1 Xiangxin Gu (Spreadtrum)
Nov 2023 Doc.: IEEE 802.11-23/2015r0 Background HT Control field and A-Control subfield are useful. Only 5 A-Control IDs are reserved for future usage. Expansion with the reserved A-Control ID ONES leads to overhead and complexity. Submission Slide 2 Xiangxin Gu (Spreadtrum)
Nov 2023 Doc.: IEEE 802.11-23/2015r0 Another way for A-Control field expansion Retry subfield is reserved in frames that are not non-A-MPDUs and under a block ack agreement. Most of exchanged frames in UHR are frames that are not non-A-MPDUs and under a block ack agreement. It is possible for other frames in UHR to check whether they are retransmissions or not, regardless Retry subfield. Retry subfield can be leveraged for A-Control field expansion. If Retry subfield is equal to 0, it is HT Control field. If Retry subfield is equal to 1, it is A-Control Expansion field. HT Duration Control PV Type Retry=0 +HTC=1 A-Control Expansion Duration PV Type Retry=1 +HTC=1 Submission Slide 3 Xiangxin Gu (Spreadtrum)
Nov 2023 Doc.: IEEE 802.11-23/2015r0 Conclusion A-Control Expansion field indicated by Retry subfield is proposed. Easier and no overhead. Submission Slide 4 Xiangxin Gu (Spreadtrum)
