For example, an apparatus may include logic and circuitry configured to cause a non Access Point (AP) (non-AP) station (STA) to identify at least one STA-blocked frequency bandwidth (BW) to be blocked for communication between the non-AP STA and an AP in a wireless communication frequency channel. For example, the non-AP STA may be configured to transmit a STA-initiated block request to the AP. For example, the STA-initiated block request may be configured to indicate a request from the non-AP STA to the AP to block the STA-blocked frequency BW for the communication between the non-AP STA and the AP.
