AI Technical Summary
Technical Problem
In wireless local area networks, the pilot subcarrier design of distributed resource units is susceptible to interference, rendering them unusable and affecting the communication performance of the devices.
Method used
By distributing pilot subcarriers discretely across multiple distributed resource units, their concentration in a single frequency band is avoided, thus ensuring continued usability even when the equipment is subject to interference.
Benefits of technology
This effectively avoids the problem of pilot subcarriers becoming unusable when interfered with in a certain frequency band, and improves the communication reliability and flexibility of the device in low-power scenarios.

Abstract
The present application supports an IEEE-related standard, for example, a protocol such as IEEE802.11be, IEEE802.11bn, IEEE802.11bf, IEEE 802.15, Wi-Fi 7, Wi-Fi 8, EHT, UHR, IMMW, UWB, or sensing, and may also support a spark link / nearlink standard protocol. Provided are a communication method and a communication apparatus. A plurality of pilot subcarriers are discretely distributed in N distributed resource units. By discretely distributing the plurality of pilot subcarriers instead of concentrating same within a certain frequency band, it is intended to prevent the situation where the pilot subcarriers in the distributed resource units become unavailable when a device experiences interference in a certain frequency band.
