Patent Images
1. A method of generating a sequence to be inserted into a preamble by an access point (AP) in a wireless local area network (LAN) system, the method comprising:
- generating a basic sequence structure comprising C48 comprising 48 tones and having 12 non-zero values, X6 comprising 6 tones and having one non-zero value, and X5 comprising five tones and having one non-zero value;
determining X1 that is a non-zero value included in the X6 and X2 that is a non-zero value included in the X5;
selecting any one of a plurality of predetermined phase rotation factors with respect to a bandwidth for communication with a user equipment (UE); and
generating a sequence inserted into a preamble to be transmitted to the UE using the basic sequence structure and the selected phase rotation factor,wherein the selected phase rotation factor is applied in a unit of the basic sequence structure that is repeatedly included in the sequence once or more.

Abstract
Disclosed is a sequence generation method comprising: generating a basic sequence structure including C48 having 48 tones, X6 having six tones, and X5 having five tones; selecting any one of a plurality of phase rotation factors predetermined for a bandwidth; and generating a sequence to be inputted into a preamble to be transmitted to a terminal, by using the phase rotation factor, applied in basic sequence structural units, and the basic sequence structure.

10. An access point (AP) for generating a sequence to be inserted into a preamble in a wireless local area network (LAN) system, the AP comprising:
-
a transmitter; a receiver; and a processor connected to the transmitter and the receiver and configured to generate a sequence, wherein; the processor generates a basic sequence structure comprising C48 comprising 48 tones and having 12 non-zero values, X6 comprising 6 tones and having one non-zero value, and X5 comprising five tones and having one non-zero value, determines X1 that is a non-zero value included in the X6 and X2 that is a non-zero value included in the X5, selects any one of a plurality of predetermined phase rotation factors with respect to a bandwidth for communication with a user equipment (UE), and generates a sequence inserted into a preamble to be transmitted to the UE using the basic sequence structure and the selected phase rotation factor; and the selected phase rotation factor is applied in a unit of the basic sequence structure that is repeatedly included in the sequence once or more. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
