Abstract

An apparatus and a method for allocating a multiple resource unit (RU) for a user in a wireless local area network (WLAN) system are provided. A transmission device of the WLAN system includes a transceiver that generates a physical layer convergence protocol (PLCP) protocol data unit (PPDU) including a preamble and a payload and transmitting the generated PPDU to at least one receiving device and a processor controlling the transceiver. The preamble includes a plurality of training fields and a plurality of signaling fields. Resource unit (RU) allocation information on the at least one receiving device is included in one of the plurality of signaling fields. The RU allocation information comprises a first subfield indicating an arrangement of RUs in a frequency domain corresponding to the PPDU and a second subfield indicating a part of the RUs to be combined to form a multiple RU.

Description

[0001] Cross References to Related Applications [0002] This application is related to and requires U.S. Provisional Patent Application No. 62 / 984,556 filed with the United States Patent and Trademark Office on March 3, 2020 and Korean Patent Application No. 10-2020-0069199 filed with the Korean Intellectual Property Office on June 8, 2020 Its priority, its entire disclosure is hereby incorporated by reference. technical field [0003] The present disclosure relates generally to wireless communications, and more particularly to wireless local area network (WLAN) based communications that allocate resource units (RUs) to users. Background technique [0004] WLAN is a technology used to wirelessly connect two or more devices to each other, where the devices are located in a local environment such as a building or a campus. A WLAN can operate in an infrastructure mode where an access point (AP) serves multiple user devices, such as smartphones and computers, and the AP can ac...
