Abstract: A wireless local area network station (STA) changes a receiver operating mode (ROM) and saves power by influencing when a ROM-conforming access point (AP) transmission takes place. The STA evaluates candidate delay regimes after a negotiation exchange with the STA. The STA then instructs the AP of a selected delay regime which the AP is permitted to use when transmitting data according to the changed ROM. The ROM can involve a change in the system bandwidth demodulated by the STA and/or the number of spatial streams demodulated by the STA. The delay regime can allow the AP to transmit with little or no delay based on the changed ROM, or the delay regime may require a fixed time delay before the AP transmits according to the changed ROM.
