July, 2016 Abstract This contribution proposes a rule setting for the Trigger Frame Per User Info order to Optimize STA power consumption Simplify STA implementation for UL OFDMA transmission Zhou Lan, Broadcom et al
12
CID 558 July, 2016 CID Comment Proposed change Resolution 558
Trigger frame for random access is never defined The trigger frame for random access shall be defined, e.g. as the trigger frame in which at least one User Identifier corresponds to a group of STAs Revised- Agree in principle Additional ruling of the sequence of the Per User info should apply as provided by xxx document Zhou Lan, Broadcom et al

Recap- passed motions July, 2016
When an STA has a frame to send, it initializes its OBO (OFDMA Back-off) to a random value in the range 0 to CWO (OFDMA Contention window). For an STA with non-zero OBO value, it decrements its OBO by 1 in every RU assigned to AID value TBD within the TF-R. For a STA, its OBO decrements by a value, unless OBO=0, equal to the number of RUs assigned to AID value TBD in a TF-R. OBO for any STA can only be 0 once every TF-R. A STA with OBO decremented to 0 randomly selects any one of the assigned RUs for random access and transmits its frame [MU Motion 27, September 17, 2015, see [121]] The spec shall define that AID=0 in the User Identifier subfield of the Per User Info field in a Trigger Frame indicates the resource allocation can be used for random access by any STA [May 2016, see [168]] Frame Control Duration (RA) TA Common Info Per User Info … Padding FCS Octets: 2 6 TBD TBD 4 Zhou Lan, Broadcom et al

Problem of randomly ordered Per User Info fields
Month Year Doc Title Problem of randomly ordered Per User Info fields July, 2016 When parsing through the randomly sequenced per user information, STAs have to remember all the Per User Info fields with AID=0 to figure out the parameters for OFDMA random access i.e. they need to understand how many RUs are assigned to OFDMA random access to figure out the decrements to perform the OBO operation However a STA find a Per User Info field with a matched AID value will not use OFDMA random access Consequently the previous operation of parsing and recording the Per User Info needed for OFDMA random access are purely wasted And STAs need to build logic to switch between parsing normal Per User Info field and those for OFDMA random access In order to avoid this problem we propose to allocate Per User Info field for OFDMA random access only after the Per User Info field for normal UL OFDMA transmission For the purpose of power saving For the purpose of easy implementation Frame Control Duration (RA) TA Common Info Per User Info … Octets: 2 6 TBD AID=0 AID= 1 AID=2 AID=3 Zhou Lan, Broadcom et al John Doe, Some Company

July, 2016 Straw Poll Do you agree to set the following rule for the trigger frame Per User Info field order Allocate the Per User Info fields with AID = 0 only after Per User Info fields with AID not equals to 0 and before the MAC padding field if present Yes No Abstain Zhou Lan, Broadcom et al
16
Motion Motion to move Direct TGax Editor to add the following paragraph at the end of section Trigger frame format according to the editing instruction provided by doc r0 “Per User Info fields with AID = 0 shall be allocated only after Per User Info fields with AID not equals to 0 and before the MAC padding field, if present.” Yes No Abstain Zhou Lan, Broadcom et al
