Abstract
Official abstract text for this publication.
In a WLAN, a device receives a frame where a symbol is attached to a previous version frame, the symbol including BSS information. The device determines whether the device belongs to a BSS of the frame based on the BSS information.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of receiving a frame by a device in a wireless local area network (WLAN), the method comprising: receiving a frame where a symbol is attached to a previous version frame, the symbol including basic service set (BSS) information; determining whether the device belongs to a BSS of a transmitter of the frame based on the BSS information, and setting a clear channel assessment (CCA) level based on whether the device belongs to the BSS of the transmitter of the frame, wherein the CCA level is set to a first level when the device belongs to the BSS of the transmitter of the frame and is set to a second level being higher than the first level when the device does not belong to the BSS of the transmitter of the frame. 2. The method of claim 1 , wherein the frame includes a request to send (RTS) frame or a clear to send (CTS) frame. 3. The method of claim 1 , wherein the previous version frame includes a frame supporting at least one of IEEE standard 802.11a, IEEE standard 802.11g, IEEE standard 802.11n, or IEEE standard 802.11ac. 4. The method of claim 1 , wherein the BSS information is generated based on some bits of an identifier of the BSS. 5. The method of claim 4 , wherein the BSS information is generated based on some bits of an association identifier (AID). 6. The method of claim 1 , wherein the symbol is attached to an end of the previous version frame. 7. The method of claim 1 , wherein the symbol further includes an indication for indicating any one of an uplink and a downlink. 8. The method of claim 1 , wherein the symbol further includes an indication for indicating a version of the frame. 9. A frame receiving apparatus in a wireless local area network (WLAN), comprising: a transceiver configured to receive a frame where a symbol is attached to a previous version frame, the symbol including basic service set (BSS) information; and a processor configured to determine whether a device including the frame receiving apparatus belongs to a BSS of a transmitter of the frame based on the BSS information, wherein the processor sets a clear channel assessment (CCA) level based on whether the device belongs to the BSS of the transmitter of the frame, and wherein the CCA level is set to a first level when the device belongs to the BSS of the transmitter of the frame and is set to a second level being higher than the first level when the device does not belong to the BSS of the transmitter of the frame. 10. The frame receiving apparatus of claim 9 , wherein the frame includes a request to send (RTS) frame or a clear to send (CTS) frame. 11. The frame receiving apparatus of claim 9 , wherein the previous version frame includes a frame supporting at least one of IEEE standard 802.11a, IEEE standard 802.11g, IEEE standard 802.11n, or IEEE standard 802.11ac. 12. The frame receiving apparatus of claim 9 , wherein the BSS information is generated based on some bits of an identifier of the BSS. 13. The frame receiving apparatus of claim 12 , wherein the BSS information is generated based on some bits of an association identifier (AID). 14. The frame receiving apparatus of claim 9 , wherein the symbol is attached to an end of the previous version frame. 15. The frame receiving apparatus of claim 9 , wherein the symbol further includes an indication for indicating any one of an uplink and a downlink. 16. The frame receiving apparatus of claim 9 , wherein the symbol further includes an indication for indicating a version of the frame.
