If a STA starts an OBSS_PD SR transmit power restriction period with a chosen SRG OBSS_PD level, the STA’s power as measured at the output of the antenna connector, shall be equal or lower than the calculated with this chosen SRG TXPWRmax, OBSS_PD level with Equation (27-4), with the appropriate SRG parameters according to Table 27-7 (Determining SRG OBSS PD Min and SRG OBSS PD Max values), for the transmissions of any PPDU (including HE T PPDU) until the end of the OBSS_PD SR transmit power restriction period.(#5870) Multiple ongoing OBSS_PD SR transmit power restriction periods may overlap in time. NOTE 2—The STA’s is always equal or lower than the minimum among all from ongoing TXPWRmax TXPWRmax OBSS_PD SR transmit power restriction periods. (#5207, #5496, #9315, #9946)NOTE (27-4) is equivalent to the condition defined in Equation (27-3). —Equation NOTE even if is unconstrained, the STA has to respect the transmit power restrictions defined by 11.8.6 Transmit power TXPWRmax —Anytime, selection. An example of OBSS_PD SR operation is shown in Figure 27-10 (Example of OBSS_PD SR operation).
