Abstract
The present invention provides a communication method, communication device, and communication system. These are applicable to wireless local area network systems that support 802.11 series protocols, such as IEEE 802.11ax next-generation Wi-Fi protocols like 802.11be, Wi-Fi 7, or EHT, and as an alternative example, next-generation protocols like 802.11be such as 802.11bn or Wi-Fi 8, 802.11ay, or 802.11aj, and can also be applied to UWB-based wireless personal area network systems, sensing systems, and similar systems. The first communication device generates and transmits a PPDU. Accordingly, the second communication device receives and parses the PPDU. The bandwidth for transmitting the PPDU may include 128 subcarriers, with more than 6 pilot subcarriers among the 128 subcarriers. By using the method described above, the packet error rate is effectively reduced.
