Abstract

Methods, computer readable media, and wireless apparatuses are disclosed. The apparatuses including processing circuitry configured to: associate with a master station, decode a frame, where the frame comprises a first duration and a transmitter address and determine that the frame is an intra basic service set (Intra-BSS), an inter (Inter-BSS), or an unclassified frame, where the unclassified frame is the Intra-BSS frame or the Inter-BSS frame. The processing circuitry may be further configured to set an Intra-BSS network allocation vector (NAV) to the first duration if the first duration is longer than a current duration of the Intra-BSS NAV and the frame is determined to be the intra-BSS frame and set the second NAV to the first duration if the first duration is longer than a current duration of the second NAV and the frame is determined to be the inter-BSS frame or the unclassified frame.

in response to the trigger frame indicating that the HE STA should respond to the trigger frame, determine whether to respond to the trigger frame without considering the intra-BSS NAV and by determining whether the basic NAV is 0; and in response to a determination to respond to the trigger frame, generate signaling to cause the HE STA to transmit a physical layer convergence procedure (PLCP) protocol data unit (PPDU) to the HE AP.

4 . The apparatus of claim 2 , wherein the frame is included in a physical layer (PHY) protocol data unit (PPDU), and the PPDU comprises a first BSS color, and wherein identify the frame as the intra-BSS frame, the inter-BSS frame, or the frame that cannot be identified as the intra-BSS frame or the inter-BSS frame further comprises:
identify the frame as the intra-BSS frame if a second BSS color associated with a HE access point (AP) matches the first BSS color, wherein the HE STA is associated with the HE AP.

5 . The apparatus of claim 2 , wherein the frame is included in a physical layer (PHY) protocol data unit (PPDU), and the PPDU comprises a first basic service set identification (BSSID), and wherein identify the frame as the intra-BSS frame, the inter-BSS frame, or the frame that cannot be identified as the intra-BSS frame or the inter-BSS frame further comprises:
identify the frame as the intra-BSS frame if a second BSSID associated with a HE access point (AP) matches the first BSSID, wherein the HE STA is associated with the HE AP.

6 . The apparatus of claim 2 , wherein the frame is included in a physical layer (PHY) protocol data unit (PPDU), and the PPDU comprises a first basic service set identification (BSSID), and wherein identify the frame as the intra-BSS frame, the inter-BSS frame, or the frame that cannot be identified as the intra-BSS frame or the inter-BSS frame further comprises:
identify the frame as the inter-BSS frame if the first BSSID does not match a second BSSID associated with a HE access point (AP), wherein the HE STA is associated with the HE AP.

7 . The apparatus of claim 6 , wherein the frame is a contention-free (CF) end frame, and wherein the processing circuitry is further configured to:
