Abstract

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.

First claim

What is claimed is:

1 . An apparatus comprising 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; and transmit a STA-initiated block request to the AP, the STA-initiated block request 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.

2 . The apparatus of claim 1 configured to cause the non-AP STA to process a response from the AP to identify whether or not the STA-initiated block request is approved by the AP.

3 . The apparatus of claim 1 , wherein the STA-initiated block request comprises a duration field to indicate a duration for blocking the STA-blocked frequency BW for the non-AP STA.

4 . The apparatus of claim 1 configured to cause the non-AP STA to transmit a termination message to request the AP to terminate blocking of the STA-blocked frequency BW for the non-AP STA.

5 . The apparatus of claim 1 , wherein the STA-initiated block request comprises a STA-initiated puncturing request to request the AP to puncture the STA-blocked frequency BW for the STA.

6 . The apparatus of claim 1 configured to cause the non-AP STA to transmit the STA-initiated block request in a parameter update request comprising one or more parameters to be updated according to an operation mode of the non-AP STA.

7 . The apparatus of claim 1 , wherein the STA-initiated block request comprises an indication of a STA-blocked Resource Unit (RU), which comprises the STA-blocked frequency BW.

8 . The apparatus of claim 7 , wherein the STA-initiated block request is configured to indicate to the AP a request to block the STA-blocked RU and any RU having an overlap with the STA-blocked RU.

9 . The apparatus of claim 7 , wherein the STA-initiated block request comprises a bitmap including a plurality of bits corresponding to a plurality of RUs, wherein a bit value of a bit is to indicate whether or not an RU corresponding to the bit is to be blocked for the non-AP STA.

10 . The apparatus of claim 1 , wherein the STA-initiated block request comprises a center-frequency value to indicate a center frequency of the STA-blocked frequency BW, and a BW value to indicate a BW of the STA-blocked frequency BW.

11 . The apparatus of claim 1 , wherein the STA-initiated block request comprises a blocked Resource Unit (RU) field comprising a predefined RU-set value selected from a plurality of predefined RU-set values mapped to a plurality of predefined RU sets, respectively, wherein the predefined RU-set value is to indicate a set of one or more RUs having an overlap with the STA-blocked frequency BW.

12 . The apparatus of claim 1 , wherein the STA-initiated block request is configured to indicate a request from the non-AP STA to the AP to block the STA-blocked frequency BW for any data transmission from the AP to the non-AP STA.

13 . The apparatus of claim 1 , wherein the STA-initiated block request is configured to indicate a request from the non-AP STA to the AP to block the STA-blocked frequency BW for any Resource Unit (RU) allocation to be provided by the AP to the non-AP STA.

14 . The apparatus of claim 1 configured to cause the non-AP STA to identify the STA-blocked frequency BW based on an identified interference over the STA-blocked frequency BW.

15 . The apparatus of claim 1 configured to cause the non-AP STA to identify the STA-blocked frequency BW based on an identified platform interference over the STA-blocked frequency BW, the identified platform interference comprises interference from one or more platform components of a platform comprising the non-AP STA.

16 . The apparatus of claim 1 configured to cause the non-AP STA to identify the STA-blocked frequency BW based on an identified interference from a memory of a platform comprising the non-AP STA.

17 . The apparatus of claim 1 configured to cause the non-AP STA to identify the STA-blocked frequency BW based on one or more real-time operation parameters of one or more platform components of a platform comprising the non-AP STA.

18 . The apparatus of claim 1 comprising a radio to transmit the STA-initiated block request to the AP, one or more antennas connected to the radio, and a processor to execute instructions of an operating system.

19 . A product comprising one or more tangible computer-readable non-transitory storage media comprising instructions operable to, when executed by at least one processor, enable the at least one processor 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; and transmit a STA-initiated block request to the AP, the STA-initiated block request 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.

20 . The product of claim 19 , wherein the instructions, when executed, cause the non-AP STA to process a response from the AP to identify whether or not the STA-initiated block request is approved by the AP.
