CPC H04L 5/0044 (2013.01) [H04L 1/08 (2013.01); H04W 84/12 (2013.01)] | 15 Claims |
1. A method performed in a wireless local area network (LAN), the method comprising:
generating an extremely high throughput (EHT) physical protocol data unit (PPDU) based on a duplicate transmission mode,
wherein the EHT PPDU includes a universal signal (U-SIG) field for interpreting the EHT PPDU, an EHT signal (EHT-SIG) field being contiguous to the U-SIG field, a short training field (STF) being contiguous to the EHT-SIG field, a long training field (LTF) being contiguous to the STF, and a data field being contiguous to the LTF;
wherein the U-SIG field has a length of 2 symbols,
wherein the U-SIG field includes a type field having a length of 2 bits, and a value of the type field is related to the duplicate transmission mode,
wherein the EHT PPDU is an 80 MHZ EHT PPDU, the U-SIG field is duplicated over each 20 MHz subchannel in the 80 MHz EHT PPDU, and the EHT-SIG field includes a content channel which is duplicated over each 20 MHz subchannel in the 80 MHz EHT PPDU,
wherein the data field includes a first 484-tone resource unit (RU) and a second 484-tone RU, and the first 484-tone RU is duplicated to the second 484-tone RU,
wherein the STF is configured based on an STF sequence defined for 80 MHz transmission, and
wherein the LTF is configured based on an LTF sequence defined for 80 MHz transmission; and
transmitting the EHT PPDU.
