Abstract
Embodiments of the present invention provide duplication schemes for control frames to extend the range of LPI in the 6 GHz wireless band for EHT WLAN. Duplicate 20 MHz legacy preambles containing L-STF, L-LTF, L-SIG and RL-SIG, U-SIG and EHT-SIG fields may be used to transmit beacon and other control frames using duplicate PPDUs to extend transmission range thereof. Non-HT duplication can be performed to maintain backwards compatibility with legacy devices. HE duplication can include duplication of a 20 MHz HE SU PPDUs over 40 MHz, 80 MHz, 160 MHz or 320 MHz portions, for example. DCM+MCSor duplication over DCM+MCSmay be applied to the payload, and a duplication indication is inserted in the U-SIG field or EHT-SIG field to indicate if the duplication is applied to the payload over DCM+MCS
