Title:
PPDU TRANSMISSION METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/012297
Kind Code:
A1
Abstract:
Provided are a PPDU transmission method and a related apparatus. The method comprises: generating a PPDU, wherein the PPDU comprises an EHT-LTF, the EHT-LTF is obtained according to a P matrix and a predefined EHT-LTF sequence, the P matrix is an orthogonal matrix with a size of n * n, n is greater than 8, and the first row of the P matrix comprises at least one element with a value of 1 and at least one element with a value of -1; and sending the PPDU. By means of the technical solution of the present application, a requirement of performing channel estimation on channels of more than eight spatial streams can be met, such that data transmission of more than eight streams can be realized, thereby improving the data transmission efficiency. The embodiments of the present application can be applied to a wireless local area network system that supports an IEEE 802.11 next-generation WiFi EHT protocol, for example, 802.11 protocols such as 802.11be.
