IEEE P802.11 Wireless LANs Abstract Proposed language to address the issue of disallowed subchannels. The proposed change is to add a new field to the end of the HE Operation IE called Operational Subchannel Information field. One additional bit called Punctured Operation is added inside of the HE Operation Information field to signal the presence/absence of the new field The new field is a combination of resolution indication, length and a bit map, where the resolution is a coded 3 bit value and the length is a 3 bit value and the bit map is the length of octets indicated in the length field. Each bit of the bitmap corresponds to a subchannel of the resolution 20 MHz indicated in the resolution field. The lowest numbered bit corresponds to the subchannel with the lowest frequency of the BSS operating channel, etc. A bit set to 1 indicates transmissions are allowed on that subchannel. A bit set to 0 indicates transmission is not allowed on that subchannel. The absence of the field indicates no puncturing, i.e. transmission is allowed on all subchannels of the BSS channel width. Corresponding behavioral language is added to subclause 27. The proposed changes on this document are on TGax Draft 2.1. REVISION NOTES: R0: initial
