[email protected] Kazuyuki Sakoda [email protected] William Carney [email protected] Submission Slide 10 Jan 2016 802.11-16/0051r0 Introduction Trigger type (allowed response type / Trigger frame variant) is in the common info field to indicate the allowed response type of the UL MAC frames MAC header FC ... Common part PPDU length CP + HE LTF type HE-SIG-A Content ... Trigger

Type Per STA part Type Specific Common Per STA Block 1 Per STA Trigger Info 1 ... Per STA Block N FCS Per STA Type Specific Info 1 In this contribution, we discuss how the STAs respond given the allowed response type Submission Slide 11 David Xun Yang et al. (Huawei) Jan 2016 802.11-16/0051r0 Response Given the Trigger Type When the AP sends a trigger frame variant, e.g., TF for CSI (or BF report poll trigger), here are several options for the response rule Opt1: The response shall only contain the frame with required type; if there is no frame with the required type, the STA shall transmit QoS Null frame Opt2: The response shall contain at least frame with required type if the required type is available at the STA side; if there is no frame with the required type, the STA shall transmit QoS Null frame Opt3: The response shall contain at least the frame with required type if the required type is available at the STA side; if there is no frame with the required type, , the STA can transmit other frame(s) without required type restriction (e.g., data frame) AP NDPA NDP

TF for CSI AP Opt1 or 2 NDPA NDP Opt3 TF for CSI STA1 BF Report STA1 BF Report STA2 BF Report STA2 BF Report STA3 (Missed NDPA or NDP) Submission STA3 (Missed NDPA or NDP) Slide 12 Data David Xun Yang et al. (Huawei) Jan 2016 802.11-16/0051r0 Pros. VS. Cons. Opt1: The response shall only contain the frame with required type if the required type is available at the STA side; if there is no frame with the required type, the STA shall transmit QoS Null frame Opt2: The response shall contain at least frame with required type if the required type is available at the STA side; if there is no frame with the required type, the STA shall transmit QoS Null frame

Pros: easy for implementation, aggregation of other types of MAC frames (e.g., data frame) will increase the efficiency Cons: the resource will be wasted if no required response is available Opt3: The response shall contain at least the frame with required type if the required type is available at the STA side; if there is no frame with the required type, , the STA can transmit other frame(s) without required type restriction (e.g., data frame) Pros: easy for implementation and scheduling Cons: a lot of padding may exist, the efficiency is low Pros: efficiency can be high even no required response is available Cons: the implementation and state machine are very complicated. Difficult for scheduling. We prefer Opt2, and think Opt3 can be helpful Submission Slide 13 David Xun Yang et al. (Huawei) Jan 2016 802.11-16/0051r0 Reference 11-15-0132-13-00ax-spec-framework Submission Slide 14 David Xun Yang et al. (Huawei) Jan 2016 802.11-16/0051r0 Straw Poll Do you support to add the following to the SFD: If the trigger frame requests a specific frame type as response, the response to this trigger frame shall contain at least the frame with the required type if the required type is available at the STA side; if the STA has no frame with the required type, the STA should transmit QoS Null frame to AP.
