DATA TRANSMISSION METHOD AND APPARATUS IN WIRELESS LOCAL AREA NETWORK - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18309575 Titled 'DATA TRANSMISSION METHOD AND APPARATUS IN WIRELESS LOCAL AREA NETWORK'
Simplified Explanation
The abstract describes a method for transmitting High Efficiency-Long Training Field (HE-LTF) signals. The method involves determining the number of OFDM symbols and the HE-LTF sequence based on the transmission bandwidth and mode of the HE-LTF field. The time-domain signal is then sent using the determined parameters. This method results in a relatively low Peak-to-Average Power Ratio (PAPR) value.
Original Abstract Submitted
An HE-LTF transmission method is provided, including: determining, based on a total number N of space-time streams, a number N of OFDM symbols included in an HE-LTF field; determining a HE-LTF sequence in frequency domain according to a transmission bandwidth and a mode of the HE-LTF field, where the HE-LTF sequence in frequency domain includes but is not limited to a mode of the HE-LTF field sequence that is in a 1x mode and that is mentioned in implementations; and sending a time-domain signal according to the number N of OFDM symbols and the determined HE-LTF sequence in frequency domain. In the foregoing solution, a PAPR value is relatively low.
