Problems solved by technology

In other words, since only the adjacent frequency band is used as the data transmission band, the actual available frequency band cannot be used
In addition, for each sending attempt in the same Basic Service Set (BSS), traditional wireless access technologies only support a one-to-one connection between one sending terminal and one receiving terminal
Therefore, the conventional wireless access technology is inefficient because the conventional wireless access technology does not operate based on the connection environment of the terminal or the difference in transmission data characteristics

Embodiment Construction

[0067] Since the invention can be variously modified and has several embodiments, specific exemplary embodiments will be shown in the drawings and described in detail in the detailed description. It should be understood, however, that there is no intent to limit the invention to the particular exemplary embodiments, but on the contrary, the invention covers all modifications and alternatives falling within the spirit and scope of the invention.

[0068] Relative terms such as first, second, etc. may be used to describe various elements, but the elements should not be limited by the terms. These terms are only used to distinguish one element from another. For example, a first component may be named a second component, and a second component may be similarly named a first component, without departing from the scope of the present invention. The term "and / or" refers to any one or combination of a plurality of associated and described items.

[0069] When it is mentioned that a ...

Abstract

An operation method of a first communication node in a wireless communication network comprises the steps of: transmitting, to a plurality of communication nodes, a first frame comprising configuration information of a data transmission interval comprising at least one frame transmission interval; and receiving second data frame(s) from at least one of the communication nodes, among the plurality of communication nodes, during the data transmission interval. The first frame may comprise: identifier(s) indicating the plurality of communication nodes; and information for configuring a network allocation vector (NAV) for communication nodes excluding the plurality of communication nodes.

Description

technical field [0001] The present invention relates to a data frame transmission method in a wireless LAN, and more particularly, to a communication method for supporting the transmission and reception of data frames of multiple users in a distributed wireless LAN structure. Background technique [0002] In recent years, with the popularization of mobile devices, wireless local area network (wireless LAN) technology, which provides fast wireless Internet services, has attracted attention. WLAN technology enables mobile devices such as smart phones, smart tablets, laptop computers, portable multimedia players, embedded devices, etc. to wirelessly connect to the Internet over short distances based on wireless communication technology. [0003] Early WLAN technology utilizes a frequency band of about 2.4 GHz according to the Institute of Electrical and Electronic Engineers (IEEE) 802.11 standard to support a data transmission rate of about 1 Mbps to about 2 Mbps based on frequ...
