Method and apparatus for transmitting uplink in wireless communication system
First Claim
1. A method for uplink transmission in a wireless local area network (WLAN), the method comprising:
- receiving, by an access point (AP), at least one request to send (RTS) frame from a first station (STA) through at least one first channel of a plurality of channels;
transmitting, by the AP, at least one first clear to send (CTS) frame to the first STA through the at least one first channel; and
transmitting, by the AP, at least one second CTS frame to a second STA through at least one second channel of the plurality of channels even though an RTS frame is not received from the second STA,wherein the at least one first CTS frame includes STA identifier information and channel information,wherein the at least one second CTS frame includes the STA identifier information and the channel information,wherein the STA identifier information includes first identifier information indicating the first STA and second identifier information indicating the second STA, andwherein the channel information includes first channel information for a first data frame to be transmitted from the first STA and second channel information for a second data frame to be transmitted from the second STA.

Abstract
A method for transmitting an uplink includes: an STA1 transmitting to an AP each of multiple RTS frames through at least one channel from among multiple first channels; the STA1 receiving from the AP at least one CTS frame through at least one channel from among the multiple channels which have received the RTS frames; and an STA2 receiving from the AP at least one CTS frame through at least one channel from among multiple second channels, wherein the at least one CTS frame includes STA identifier information and channel information, the STA identifier information includes information for indicating the STA1 and the STA2, and wherein the channel information includes information on an uplink channel1 allocated for transmitting a data frame1 of the STA1 and information on an uplink channel2 allocated for transmitting a data frame2 of the STA2.

7. An access point (AP) for receiving uplink data in a wireless local area network (WLAN), the AP comprising:
-
a radio frequency (RF) unit configured to transmit and receive a radio signal; a processor operatively connected to the RF unit and configured to; receive at least one request to send (RTS) frame from a first station (STA) through at least one first channel of a plurality of channels; transmit at least one first clear to send (CTS) frame to the first STA through the at least one first channel; and transmit at least one second CTS frame to a second STA through at least one second channel of the plurality of channels even though an RTS frame is not received from the second STA, wherein the at least one first CTS frame includes STA identifier information and channel information, wherein the at least one second CTS frame includes the STA identifier information and the channel information, wherein the STA identifier information includes first identifier information indicating the first STA and second identifier information indicating the second STA, and wherein the channel information includes first channel information for a first data frame to be transmitted from the first STA and second channel information for a second data frame to be transmitted from the second STA. - View Dependent Claims (8, 9, 10, 11, 12)
