Title:
INFORMATION TRANSMISSION METHOD, COMMUNICATION APPARATUS, STORAGE MEDIUM, CHIP AND PROGRAM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/025113
Kind Code:
A1
Abstract:
Provided in the embodiments of the present disclosure are an information transmission method, a communication apparatus, a storage medium, a chip and a program product. The method comprises: a first device receiving a trigger-based frame from a second device, wherein the trigger-based frame comprises distributed resource unit indication information; on the basis of the distributed resource unit indication information, determining one or more distributed resource blocks, wherein each distributed resource block comprises N1 data subcarriers and N2 pilot subcarriers, and the absolute value of the difference between indexes of every two data subcarriers in N3 data subcarriers from among the N1 data subcarriers is greater than or equal to 4; and sending, on the one or more distributed resource blocks and to the second device, a response concerning the trigger-based frame. By means of the method, complete dispersion of the subcarriers comprised in a DRU can be realized, and pilot subcarriers comprised therein are also completely dispersed, such that under the same power spectral density, the maximum power amplification factor can be achieved in comparison with a continuous RU, thereby improving the transmission efficiency.
