Spatial reuse for uplink multiuser transmissions

An apparatus of a high-efficiency (HE) station (STA) (HE-STA) configured to operate in a wireless local area network (WLAN) comprising a basic service set (BSS), the BSS including at least the HE-STA and an access point (AP), the apparatus comprising:

• a memory;
• and processing circuitry coupled to the memory,
• wherein the HE STA is configured for spatial reuse (SR) operation, and
• wherein the processing circuitry is configured to:
• decode a HE signal A (HE-SIG-A) field of an HE physical layer convergence procedure (PLOP) protocol data unit (PPDU) to determine a value of a spatial reuse field;
• and
• if the HE PPDU is an overlapping basic service set (OBSS) PPDU, and if a received signal strength of a legacy portion of the HE PPDU is below an OBSS power detect (OBSS-PD) level, configure the HE-STA for transmission of a frame,
• wherein if the HE PPDU is a multi-user (MU) PPDU and the value of the spatial reuse field indicates spatial reuse (SR) restricted, the processing circuitry is to configure the HE STA to transmit the frame during a duration of a remaining portion of the HE PPDU, and
• wherein if the HE PPDU is a single-user (SU) PPDU and the value of the spatial reuse field indicates spatial reuse (SR) delay, the processing circuity is to configure the HE STA to delay transmission of the frame after the duration of the remaining portion of the HE PPDU.

A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of a high-efficiency (HE) station (STA) (HE-STA) configured to operate in a wireless local area network (WLAN) comprising a basic service set (BSS), the BSS including at least the HE-STA and an access point (AP), the processing circuitry to:

• configure the HE STA for spatial reuse (SR) operation;
• decode a HE signal A (RE-SIG-A) field of an HE physical layer convergence procedure (PLSP) protocol data unit (PPDU) to determine a value of a spatial reuse field;
• and
• if the HE PPDU is an overlapping basic service set (OBSS) PPDU, and a received signal strength of a legacy portion of the HE PPDU is below an OBSS power detect (OBSS-PD) level, configure the HE-STA for transmission of a frame,
• wherein if the HE PPDU is a multi-user (MU) PPDU and if the value of the spatial reuse field indicates spatial reuse (SR) restricted, the processing circuitry is to configure the HE STA to transmit the frame during a duration of a remaining portion of the RE PPDU, and
• wherein if the HE PPDU is a single-user (SU) PPDU and the value of the spatial reuse field indicates spatial reuse (SR) delay, the processing circuity is to configure the HE STA to delay transmission of the frame after the duration of the remaining portion of the HE PPDU.
