PHYSICAL LAYER PROTOCOL DATA UNIT FORMAT INCLUDING PADDING IN A HIGH EFFICIENCY WIRELESS LAN

摘要

The present invention relates to a Physical layer Protocol Data unit (PPDU) format including a padding. According to one aspect of the present invention, a method for transmitting data to a plurality of stations on a transmission channel by an Access Point in a WLAN may be provided. The transmission channel may be divided into a plurality of subchannels allocated to the plurality of stations. The method may include generating a padding having a length individually for each of one or more subchannels to which paddings are applied among the plurality of subchannels, the length of the padding making transmissions end simultaneously on the plurality of subchannels, and transmitting a PPDU frame including a data unit without the padding or a data unit added with the padding for each of the plurality of subchannels to the plurality of stations on the transmission channel.

1. A method for transmitting data to a plurality of Stations (STAs) on a transmission channel by an Access Point (AP) in a Wireless Local Area Network (WLAN), the transmission channel being divided into a plurality of subchannels allocated to the plurality of STAs, the method comprising:
generating a padding individually for one or more subchannels to which paddings are applied among the plurality of subchannels, wherein the padding has a length such that transmissions end simultaneously on the plurality of subchannels; and transmitting a Physical layer Protocol Data Unit (PPDU) frame including a data unit without the padding or a data unit added with the padding for each of the plurality of subchannels to the plurality of STAs on the transmission channel.
