AI Technical Summary
Technical Problem
When multiple UWB devices use a fixed UWB channel in the same indoor space, interference will occur, affecting transmission performance.
Method used
By designing a first sequence containing both non-zero and zero elements, the UWB device is instructed to transmit on different channels. Frequency hopping transmission is employed to ensure that the number of non-zero elements is as large as possible, the number of zero elements is reduced, and the cross-correlation between different sequences is less than or equal to a threshold, thereby achieving orthogonality or near-orthogonality.
Benefits of technology
It reduces transmission interference between multiple UWB devices, ensuring transmission performance.

Abstract
A communication method and apparatus supporting IEEE protocols, such as IEEE 802.11be / Wi-Fi 7 / EHT, IEEE 802.11bn / UHR / Wi-Fi 8, IEEE 802.15 / UWB, or IEEE 802.11bf / sensing. The method includes: determining a first sequence; and performing frequency hopping transmission based on part or all of the first sequence. The first sequence includes non-zero elements and zero elements. The non-zero elements include at least one of a first element, a second element, or a third element, respectively indicating transmission on a first channel, a second channel, and a third channel. The zero elements indicate no transmission. This technical solution, by designing the first sequence, enables UWB devices to not only increase transmission opportunities but also reduce transmission interference between devices, thus ensuring transmission performance.
