Sept. 2016 Beamforming Feedback Fragmentation Avoidance Recap: To avoid sounding feedback fragmentation, the following rule is defined in 11ax The HE beamformer shall have the supported MPDU size large enough to avoid fragmentation except when 11,454 is reached. However it is not clear whether there is specific rules about resource allocation to beamformee in Beamforming Report Poll Trigger frame. The HE sounding fragmentation method is not clearly defined in 11ax D0.1. doc.: IEEE 802.11-16/01182r0 Submission Liwen Chu, Marvell, et. al.
Sept. 2016 Beamforming Feedback Fragmentation Avoidance The following rules should be applied to 11ax sounding feedback fragmentation which is similar to 11ac: the sounding feedback shall be split into up to 8 feedback segments. Each of the feedback segments except the last shall contain the maximum number of octets allowed by the HE beamformer smaximum MPDU length capability. The feedback segments shall be sent in a single A-MPDU and shall be included in the A-MPDU in the descending order of the Remaining Feedback Segments subfield values. All segments in the first transmission The requested segments in the retransmission All segments in the retransmission should be disallowed in not request by the beamformer. The difference between HE trigger-based sounding feedback and VHT sounding feedback is that: In VHT sounding feedback, it is the beamformee to decide the resource for sounding feedback. 11ac mandates that In HE trigger-based sounding feedback, Trigger frame defines the resource of HE sounding feedback. If the resource allocated for STA s feedback is not enough, the beamformee may not be able to send sounding feedback in one A-MPDU. When the sounding feedback is retransmitted, the AP only allocates the enough resource for the retransmitted segments. If the beamformee retransmit all segments, the allocated resource may not be enough. doc.: IEEE 802.11-16/01182r0 Submission Liwen Chu, Marvell, et. al.
Sept. 2016 Beamforming Feedback Fragmentation Avoidance AP s resource allocation in Beamforming Report Poll Trigger should be defined: in Beamforming Report Poll Trigger, the allocated UL resource for one beamformee s sounding feedback shall be enough for the beamformee to transmit the requested sounding feedback in one PPDU per its Feedback type, Ng, codebook size, Nc, and Partial Bandwidth Info. doc.: IEEE 802.11-16/01182r0 STA s (beamformee s) behavior should be defined: When the AP requests retransmission of sounding feedback segments from a beamformee through Beamforming Report Poll Trigger, the beamformee shall transmit the requested segments first.

Sept. 2016 doc.: IEEE 802.11-16/01182r0 Straw Poll 1 Do you support, in Beamforming Report Poll Trigger, the allocated UL resource for one beamformee s sounding feedback shall be enough for the beamformee to transmit the requested sounding feedback in the trigger-based PPDU that is sent as a response per its Feedback type, Ng, codebook size, Nc.

Sept. 2016 doc.: IEEE 802.11-16/01182r0 Straw Poll 2 Do you the following rules apply to 11ax sounding feedback fragmentation, the sounding feedback shall be split into up to 8 feedback segments Each of the feedback segments except the last shall contain the maximum number of octets allowed by the HE beamformer s maximum MPDU length capability the request feedback segments shall be sent in a single A-MPDU and shall be included in the A- MPDU in the descending order of the Remaining Feedback Segments subfield values.
