Systems and methods for transmitting a preamble within a wireless local area network (WLAN)
First Claim
1. A method for transmitting a preamble in accordance with a wireless local area network communication protocol, the method comprising:
- obtaining a data frame for transmission compliant with the wireless local area network communication protocol;
determining that the data frame includes a first preamble portion and a second preamble portion;
transmitting the first preamble portion via beamforming based on a first beamforming matrix; and
determining whether a transmission mode of the second preamble portion is beamforming in a same way as the first preamble portion or omni-directional based on a type of the wireless local area network communication protocol;
in response to determining that the transmission mode of the second preamble portion is beamforming in the same way as the first preamble portion;
transmitting the second preamble portion via beamforming based on the first beamforming matrix.

Abstract
Some embodiments described herein provide a method for transmitting a preamble in accordance with a wireless local area network communication protocol. In some embodiments, a data frame may be obtained for transmission including a preamble compliant with the wireless local area network communication protocol. It may be determined that the preamble includes a first preamble portion that spans multiple symbol durations and a second preamble portion that spans a single symbol duration. The first preamble portion via beamforming may be transmitted based on a first beamforming matrix. When a transmission mode of the second preamble portion is beamforming, a second beamforming matrix may be generated based on the first beamforming matrix, each tone for the second preamble portion may be calculated based on the second beamforming matrix. Each calculated tone may be transmitted in accordance with the wireless local area network communication protocol.
