Method and Apparatus for Sending and Receiving Signaling in Wireless Local Area Network - A simplified explanation of the abstract

This abstract first appeared for US patent application 18166763 titled 'Method and Apparatus for Sending and Receiving Signaling in Wireless Local Area Network

Simplified Explanation

The patent application describes a method for generating a physical protocol data unit (PPDU) for a downlink multiple-user transmission in a Wi-Fi network. The PPDU includes a legacy preamble, two high efficiency Wi-Fi signaling fields (HEW-SIG1 and HEW-SIG2), and a data portion. The HEW-SIG1 includes a modulation and coding scheme (MCS) field and a frame structure indication field, while the HEW-SIG2 includes resource indication information. The method also involves sending the PPDU.

Original Abstract Submitted

A method includes generating, by an apparatus, a physical protocol data unit (PPDU) for a downlink multiple-user transmission, wherein the PPDU includes: a legacy preamble, a high efficiency Wi-Fi Signaling Field 1 (HEW-SIG1), a high efficiency Wi-Fi Signaling Field 2 (HEW-SIG2), adjacent to the HEW-SIG1, and a data portion, and wherein the HEW-SIG1 comprises a HEW-SIG2 modulation and coding scheme (HEW-SIG2 MCS) field, the HEW-SIG2 MCS field indicates a transmission modulation and coding scheme (MCS) used to transmit the HEW-SIG2, the HEW-SIG1 further comprises a frame structure indication field, and the frame structure indication field indicates whether a frame structure of a scheduling transmission is an uplink structure or a downlink structure, and the HEW-SIG2 comprises resource indication information; and sending, by the apparatus, the PPDU.
