Abstract:
TDLS support in VHT devices is enabled through the use of added VHT fields in the TDLS frames. A VHT TDLS direct link can be setup through a respective TDLS Setup Request/Response with added field announcing VHT Capabilities of the VHT device and the peer device. Added VHT Operation field in the TDLS Setup Confirm frame adds supports between VHT peer devices for non-VHT BSS and VHT BSS. Two VHT STAs can establish wider TDLS channel than BSS operating channel through TDLS establishment. VHT off channel support is enabled by adding Wide Bandwidth Channel Switch field in the TDLS Channel Switch Request frame and no changes to TDLS Channel Switch Response. A VHT Capabilities field is also added to TDLS Discovery Response frame to inform peer devices of device capabilities.
