IEEE P802.11 Wireless LANs Comment Resolution on MIMO BF misc Date: 2018-3-28 Author(s): Name Affiliation Address Phone Email Lei Huang Panasonic lei.huang@sg.panasonic.com Hiroyuki Motozuka Panasonic James Wang MediaTek CID Page Number Line Number Comment Proposed Change Resolution 1903 166 7 The MIMO BF frame has many that also may have that are located at different places in the text. This paragraph was written like all the are at the same level. e.g. the Aggregation Requested Field is part of the MIMO FBCK-REQ while the SU/MU filed is part of the MIMO Setup Control Element. and the Dialog Token field is part of the MMO BF set frame in a different part of the text. This makes it very difficult to read. Please group parameters on the same level together. In a simple example, start with defining all the parameters at the MIMO BF setup frame level, then at the MIMO setup control element level, then at Also, please refer to the correct section. Revised- Agreed in principle. In addition to the MIMO BF Setup frame, similar changes shall also be made on the MIMO BF Poll frame, MIMO BF Feedback frame and MIMO BF Selection frame. TGay editor to make the changes shown in 11-18/0610r0 under all headings that include CID 1903. 1904 166 24 The MIMO BF setup frame has many that also may have that are located at different places in the text.

the meaning of the field "Configuration .. User .. SISO ID" is somewhat misleading. The RX AWVs cannot be known by the initiator, since multiple RX AWVs can be tested for one id. They can only be inferred by responder, based on the SISO id. specified in comment. See resolution to CID 2001. TGay editor to make the changes shown in 11-18/0610r0 under all headings that include CID 2020. 2239 78 1 A STA can be excluded from MIMO training and feedback phases of BF training. In this case the excluded STA does not have a SISO ID subset index, but still needs to be signaled in the MIMO selection frame to know which RX antenna should be activated Change field name to Configureation x User y SISO ID Subset Index for antenna z / RX antenna ID add description in 10.38.9.2.3.3 for STAs excluded from MU-MIMO BF training and Feddback phases in the procedure of MIMO selection Revised- Agreed in principle. TGay editor to make the changes in 11-18/0610r0 under all headings that include CID 2239. 1342 171 19 The connection between the MU-MIMO configuration and spatial streams that can be assigned to users in (e.g.) 30.4.10.5 is extremely opaque. There is a need to define which user gets which streams Define an assignement of streams to users in each configuration Rejected- Assignment of spatial streams to users is signalled in the field of EDMG MU PPDU. It is not necessary to assign spatial streams to users in MU-MIMO transmission configuration. Proposed changes to D1.1 and 18/0299r1: Modify the change on 15 as follows (CID 1976, 2001, 2020, 2239): Field Size (bits) Meaning Element ID 8 …. MU-MIMO Transmission Configuration 1 Group User Mask for Antenna 1 32 Indicates the STA(s) in the target MU group associated with the first TX DMG antenna in the first MU-MIMO transmission configuration.
