Abstract
A method and a device for receiving and 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.
Claims5
A method for communicating in a wireless local area network (LAN), the method performed by an access point (AP) comprising:
- receiving a physical layer protocol data unit (PPDU) from a station over a transmission bandwidth;
- and
- determining whether the station is a member of a basic service set (BSS) managed by the AP based on the PPDU,
- wherein, when the PPDU is a multi-user (MU)-PPDU, the AP determines that the station is not the member of the BSS managed by the AP, and
- wherein the MU-PPDU comprises a first signal field and a second signal field, the first signal field comprising bandwidth information indicating the transmission bandwidth, the second signal field comprising user-specific information comprising allocation for orthogonal frequency division multiple access (OFDMA) transmission.
A device configured for communicating in a wireless local area network (LAN), the device comprising:
- a processor;
- and
- memory disposed to said processor, said memory including instructions, when executed by said processor cause the device to:
- receive a physical layer protocol data unit (PPDU) from a station over a transmission bandwidth;
- and
- determine whether the station is a member of a basic service set (BSS) managed by the device based on the PPDU,
- wherein, when the PPDU is a multi-user (MU)-PPDU, the device determines that the station is not the member of the BSS managed by the device, and
- wherein the MU-PPDU comprises a first signal field and a second signal field, the first signal field comprising bandwidth information indicating the transmission bandwidth, the second signal field comprising user-specific information comprising allocation for orthogonal frequency division multiple access (OFDMA) transmission.
