==METHOD AND APPARATUS FOR APPLYING OPTIMIZED PHASE ROTATION BY CONSIDERING PREAMBLE PUNCTURING IN 802.11AX AND VARIOUS RF CAPABILITIES - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240048423 titled 'METHOD AND APPARATUS FOR APPLYING OPTIMIZED PHASE ROTATION BY CONSIDERING PREAMBLE PUNCTURING IN 802.11AX AND VARIOUS RF CAPABILITIES

==Simplified Explanation==

The abstract describes a method and apparatus for transmitting an EHT PPDU (Enhanced High Throughput Physical Protocol Data Unit) to a wireless LAN system. The transmission device generates the EHT PPDU and transmits it to a reception device through a 320 MHz band with a punctured partial band based on an RF. The legacy preamble, consisting of an L-STF (Legacy Short Training Field) and an L-LTF (Legacy Long Training Field), is generated by applying a first phase rotation value. This first phase rotation value is determined based on a first method and a second method. The first method is for acquiring an optimum PAPR (Peak-to-Average Power Ratio) in the L-LTF, while the second method is for acquiring an optimum PAPR based on the maximum transmission bandwidth supported by the RF. The first phase rotation value is acquired based on a second phase rotation value and a third rotation value. The second phase rotation value is a phase rotation value that repeats a phase rotation value defined with respect to an 80 MHz band in an 802.11ax system. The third phase rotation value is a phase rotation value defined by 80 MHz band units in the 320 MHz band.

==Original Abstract Submitted==

a method and an apparatus for transmitting an eht ppdu to a wireless lan system are presented. particularly, a transmission device generates an eht ppdu, and transmits the eht ppdu to a reception device through a 320 mhz band of which a partial band is punctured on the basis of an rf. a legacy preamble includes an l-stf and an l-ltf. the legacy preamble is generated by applying a first phase rotation value. the first phase rotation value is determined on the basis of a first method and a second method. the first method is for acquiring an optimum papr in the l-ltf. the second method is for acquiring an optimum papr on the basis of a maximum transmission bandwidth supported by the rf. the first phase rotation value is acquired on the basis of a second phase rotation value and a third rotation value. the second phase rotation value is a phase rotation value which repeats a phase rotation value that is defined with respect to an 80 mhz band in an 802.11ax system. the third phase rotation value is a phase rotation value that is defined by 80 mhz band units in the 320 mhz band.
