Method of reporting received signal strength on per frame basis in Wi-Fi network
Aspects of the present disclosure are drawn to a client device for use with an access point device. The client device includes: a memory; and a processor configured to execute instructions stored on the memory to cause the client device to: obtain a value associated with a capability of the client device, create a response including a header and a payload, the header including a reserved field including a bit reporting that the payload of the response includes the value associated with the capability, and transmit the response to the APD.
1. An access point device for determining that a client device supports one or more capabilities, the access point device comprising:
a memory; and
a processor configured to execute one or more instructions stored on the memory to cause said client device to:
generate an Add Block Ack (ADDBA) request frame, wherein the ADDBA request frame comprises an ADDBA capabilities field;
transmit the ADDBA request frame to the client device to establish a Block Ack session;
receive an ADDBA response frame from the client device based on the ADDBA request frame, wherein the ADDBA response frame comprises a value associated with a capability of the client device; and
determine that the client device supports the one or more capabilities based on the ADDBA response frame, wherein at least one of the one or more capabilities indicate that the client device is capable of reporting channel condition.
2. The access point device of claim 1 , wherein the ADDBA request frame comprises an ADDBA extension element that includes the ADDBA capabilities field.
3. The access point device of claim 1 , wherein the ADDBA extension element comprises an element identifier describing a type of element, a length of the ADDBA capabilities field, and the ADDBA capabilities field.
4. The access point device of claim 1 , wherein the ADDBA capabilities field specifies whether the client device is capable of reporting one or more channel power measurements.
5. The access point device of claim 1 , wherein the ADDBA response frame includes a Block Ack header and a Block Ack payload, wherein the value associated with the capability of the client device resides in a Block Ack information field of the Block Ack payload.
6. The access point device of claim 5 , wherein the processor is further configured to execute the one or more instructions stored on the memory to additionally cause the access point device to:
obtain as the value of the capability of the client device in the Block Ack information field of the Block Ack payload a received channel power indicator indicative of radio frequency power received on a channel by the client device.
7. The access point device of claim 5 , wherein the processor is further configured to execute the one or more instructions stored on the memory to additionally cause the access point device to:
obtain as the value of the capability of the client device in the Block Ack information field of the Block Ack payload a received signal-to-noise indicator indicative of noise received on a channel by the client device.
8. A method for an access point device to determine that a client device supports one or more capabilities, the method comprising:
generating an Add Block Ack (ADDBA) request frame, wherein the ADDBA request frame comprises an ADDBA capabilities field;
transmitting the ADDBA request frame to the client device to establish a Block Ack session;
receiving an ADDBA response frame from the client device based on the ADDBA request frame, wherein the ADDBA response frame comprises a value associated with a capability of the client device; and
determining that the client device supports the one or more capabilities based on the ADDBA response frame, wherein at least one of the one or more capabilities indicate that the client device is capable of reporting channel condition.
9. The method of claim 8 , wherein the ADDBA request frame comprises an ADDBA extension element that includes the ADDBA capabilities field.
10. The method of claim 8 , wherein the ADDBA extension element comprises an element identifier describing a type of element, a length of the ADDBA capabilities field, and the ADDBA capabilities field.
11. The method of claim 8 , wherein the ADDBA capabilities field specifies whether the client device is capable of reporting one or more channel power measurements.
12. The method of claim 8 , wherein the ADDBA response frame includes a Block Ack header and a Block Ack payload, wherein the value associated with the capability of the client device resides in a Block Ack information field of the Block Ack payload.
13. The method of claim 12 , the method further comprising:
obtaining as the value of the capability of the client device in the Block Ack information field of the Block Ack payload a received channel power indicator indicative of radio frequency power received on a channel by the client device.
14. The method of claim 12 , the method further comprising:
obtaining as the value of the capability of the client device in the Block Ack information field of the Block Ack payload a received signal-to-noise indicator indicative of noise received on a channel by the client device.
15. A non-transitory computer-readable medium of an access point device storing one or more instructions for determining that a client device supports one or more capabilities, which when executed by a processor of the access point device, cause the access point device to perform one or more operations comprising:
generating an Add Block Ack (ADDBA) request frame, wherein the ADDBA request frame comprises an ADDBA capabilities field;
transmitting the ADDBA request frame to the client device to establish a Block Ack session;
receiving an ADDBA response frame from the client device based on the ADDBA request frame, wherein the ADDBA response frame comprises a value associated with a capability of the client device; and
determining that the client device supports the one or more capabilities based on the ADDBA response frame, wherein at least one of the one or more capabilities indicate that the client device is capable of reporting channel condition.
16. The non-transitory, computer-readable medium of claim 15 , wherein at least one of:
the ADDBA request frame comprises an ADDBA extension element that includes the ADDBA capabilities field; and
the ADDBA extension element comprises an element identifier describing a type of element, a length of the ADDBA capabilities field, and the ADDBA capabilities field.
17. The non-transitory, computer-readable medium of claim 15 , wherein the ADDBA capabilities field specifies whether the client device is capable of reporting one or more channel power measurements.
18. The non-transitory, computer-readable medium of claim 15 , wherein the ADDBA response frame includes a Block Ack header and a Block Ack payload, wherein the value associated with the capability of the client device resides in a Block Ack information field of the Block Ack payload.
19. The non-transitory, computer-readable medium of claim 18 , wherein the one or more instructions when executed by the processor further cause the access point device to further perform the one or more operations comprising:
obtaining as the value of the capability of the client device in the Block Ack information field of the Block Ack payload a received channel power indicator indicative of radio frequency power received on a channel by the client device.
20. The non-transitory, computer-readable medium of claim 18 , wherein the one or more instructions when executed by the processor further cause the access point device to further perform the one or more operations comprising:
obtaining as the value of the capability of the client device in the Block Ack information field of the Block Ack payload a received signal-to-noise indicator indicative of noise received on a channel by the client device.
