  • Patent number: 11882596
    Abstract: Embodiments of the present invention are drawn to electronic systems that perform EHT operations for a wireless network supporting a 160+160 MHz/320 MHz operating mode. RTS/CTS frame exchange sequences and TXOP truncation can be performed using punctured preambles according to subchannels indicated in a bitmap subfield (e.g., an Allowed Bitmap Subfield). Preamble puncturing is supported for EHT PPDUs transmitted to multiple STAs using MU-RTS/MU-CTS frames transmitted in non-HT duplicate PPDUs. Preamble puncturing is also supported for an EHT PPDU transmitted to a single STA. The RTS and CTS frames can be sent in a non-HT duplicate PPDU with preamble puncturing, for example.
