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

摘要

The present invention provides a new downlink frame format to support MU-MIMO and OFDMA, and methods, apparatuses, etc. therefor. In an aspect of the present invention, a method for transmitting data to a plurality of STAs by an AP in a WLAN may include generating a HE-LTF field for the plurality of STAs, and transmitting a PPDU frame to the plurality of STAs, the PPDU frame including the HE-LTF field and data for the plurality of STAs. The data for the plurality of STAs may be transmitted to different STA on each of a plurality of subchannels, and a starting point of the HE-LTF field may be same across the plurality of STAs and an end point of the HE-LTF field may be same across the plurality of STAs.

1. A method for transmitting data to a plurality of Stations (STAs) by an Access Point (AP) in a Wireless Local Area Network (WLAN), the method comprising:
generating a High Efficiency-Long Training Field (HE-LTF) field for the plurality of STAs; and transmitting a Physical layer Protocol Data Unit (PPDU) frame to the plurality of STAs, the PPDU frame including the HE-LTF field and data for the plurality of STAs, wherein the data for the plurality of STAs are transmitted to different STA on each of a plurality of subchannels, and wherein a starting point of the HE-LTF field is same across the plurality of STAs and an end point of the HE-LTF field is same across the plurality of STAs.
