Abstract
The present invention relates to a wireless communication method for suggesting a packet preamble structure for efficient communication in a wireless communication environment in which a legacy terminal and a non-legacy terminal are mixed, and a wireless communication terminal using the same. For this, the present invention provides a wireless communication method including: generating a packet including a first preamble and a second preamble, wherein a first symbol and a second symbol of the second preamble are modulated using binary phase shift keying (BPSK); and transmitting the generated packet and a wireless communication terminal using the same.
Claims16
A wireless communication terminal comprising:
- a transceiver;
- and
- a processor,
- wherein the processor is configured to:
- receive, through the transceiver, a first preamble of a wireless packet,
- receive, through the transceiver, a second preamble of the wireless packet according to an identified configuration of the second preamble,
- wherein the configuration of the second preamble is identified based at least in part on a detected constellation of a specific symbol of the second preamble,
- wherein when the detected constellation of the specific symbol is a first constellation, the second preamble includes a high efficiency signal A field (HE-SIG-A) composed of four symbols, and
- wherein when the detected constellation of the specific symbol is a second constellation, the second preamble includes an HE-SIG-A composed of two symbols and a high efficiency signal B field (HE-SIG-B).
A wireless communication method of a terminal, the method comprising:
- receiving a first preamble of a wireless packet;
- and
- receiving a second preamble of the wireless packet according to an identified configuration of the second preamble,
- wherein the configuration of the second preamble is identified based at least in part on a detected constellation of a specific symbol of the second preamble,
- wherein when the detected constellation of the specific symbol is a first constellation, the second preamble includes a high efficiency signal A field (HE-SIG-A) composed of four symbols, and
- wherein when the detected constellation of the specific symbol is a second constellation, the second preamble includes an HE-SIG-A composed of two symbols and a high efficiency signal B field (HE-SIG-B).
