Abstract
A method and a device for receiving transmitting data in in a wireless local area network are provided. The device receives a physical layer protocol data unit (PPDU) from a station over a transmission bandwidth and determines whether the station is a member of a basic service set (BSS) managed by the device based on the PPDU. When the PPDU is a multi-user (MU)-PPDU, the AP determines that the station is not a member of the BSS managed by the AP. Such MU-PPDU includes a first signal field and a second signal field, the first signal field having bandwidth information indicating the transmission bandwidth, the second signal field having user-specific information with allocation for orthogonal frequency division multiple access (OFDMA) transmission.
Claims17
A station in a wireless network, the station comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories, the one or more processors configured to cause:
- receiving a PPDU (Physical layer Protocol Data Unit) including a BSS (basic service set) color value and a color indication, wherein the BSS color value identifies a first BSS,
- receiving a VHT (Very High Throughput) PPDU, wherein the VHT PPDU comprises a partial AID (Association Identifier), and
- determining whether the VHT PPDU is transmitted from the first BSS based on the partial AID and the BSS Color value when the color indication has a first value.
An Access Point (AP) in a wireless network, the AP comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories, the one or more processors configured to cause:
- transmitting a PPDU (Physical layer Protocol Data Unit) including a BSS (basic service set) color value and a color indication, wherein the BSS color value identifies a first BSS, and
- transmitting a VHT (Very High Throughput) PPDU, wherein the VHT PPDU comprises a partial AID (Association Identifier),
- wherein a part of the partial AID of the VHT PPDU is equal to a part of the BSS color value of the PPDU when the VHT PPDU is transmitted from the first BSS.
An Access Point (AP) in a wireless network, the AP comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories, the one or more processors configured to cause:
- receiving a VHT (Very High Throughput) PPDU, wherein the VHT PPDU comprises a partial AID (Association Identifier),
- comparing the partial AID with a BSSID (Basic Service Set Identifier) of a first BSS (Basic Service Set) which the AP is associated with,
- determining that the VHT PPDU is transmitted from the first BSS when the partial AID is equal to a part of the BSSID.
