METHOD AND APPARATUS FOR TRANSMITTING CHANNEL PARAMETER INFORMATION

摘要

The present invention relates to a method and apparatus for transmitting channel parameter information. A method for transmitting a frame in consideration of a channel environment includes the steps of: receiving long training field (LTF) setting information from a station; creating a frame including an LTF, a plurality of divided data fields, and an additional LTF on the basis of the LTF setting information; and transmitting the frame, wherein the LTF positions are ahead of the plurality of divided data fields, the additional LTF positions are between or behind the plurality of divided data fields, and the LTF setting information can be created on the basis of the movement of the station. Therefore, channel estimation performance can be increased.

1. A method of transmitting a frame according to a channel environment, the method comprising:
receiving LTF (long training field) configuration information from a station; generating a frame including an LTF, a plurality of split data fields, and an additional LTF based on the LTF configuration information; and transmitting the frame, wherein the LTF is located ahead of the plurality of split data fields, and the additional LTF is located between the plurality of split data fields or behind the plurality of split data fields, and wherein the LTF configuration information is generated based on a move of the station.
