Abstract: Methods, apparatuses, devices, and computer program products for changing NPCA primary channel are described. A non-AP STA transmits, to an AP, a first frame including a first non-primary channel access, NPCA, information field including a first capability subfield that includes information indicative of a capability of the non-AP STA to switch from a basic service set, BSS, primary channel to a NPCA primary channel that lies outside of a current operating channel width of the non-AP STA and that lies within a BSS channel width of the AP, the current operating channel width including the BSS primary channel. The non-AP STA receives a management frame including a second NPCA information field including a control subfield that indicates enablement information for switching from the BSS primary channel to a specific NPCA primary channel outside the current operating channel width of the non-AP STA, and switches to the specific NPCA primary channel.

Abstract: A station (STA) receives a parameterized spatial reuse (PSR) reception (PSRR) trigger frame from an overlapping basic service set access point (AP). The PSRR trigger frame includes a special user information field including a plurality of PSR subfields, each PSR subfield including a respective PSR value. The STA determines a received power level of the PSRR frame per each 20 MHz channel over which the PSRR frame is received. The STA determines a transmission power for a PSR transmission (PSRT) for transmission to an associated AP based on a minimum PSR value determined as a minimum of the plurality of respective PSR values, the determined received power level of the PSRR frame at the STA per each 20 MHz channel over which the PSRR frame is received, and an effective bandwidth of the PSRT frame. The station transmits the PSRT frame at the determined transmission power.

Abstract: An association and authentication medium access control (aaMAC) address is assigned a station (STA) during association with an AP. STAs communicate initially using the aaMAC address and may communicate subsequently using over-the-air MAC (otaMAC) addresses to maintain anonymity. Filtering techniques may be used to associate frames with active aaMAC addresses with temporary otaMAC addresses that are exchanged between nodes using Active MAC Address Set Request and Response frames. A STA sends a frame to a node (e.g., STA2) using an association and aaMAC address associated with the STA and sends a first active MAC address set request to the node including an otaMAC address for wireless transmissions from the STA. The reciprocal process is performed by STA2, and subsequent communications may be exchanged between STAs using the otaMAC addresses and/or the aaMAC addresses randomly to enhance privacy.
