Lu discloses performing spatial reuse based on a comparison between a received signal strength and a threshold but fails to explicitly recite that said threshold is received and therefore fails to disclose “receive an indication of a threshold value associated with a selection between a spatial reuse communication mode”.
In a related field of endeavor, Wang discloses:

(US Patent Publication 2021/0360694 herein after referenced as Pandian).
Regarding claim 20 and claim 48, Lu in view of Wang discloses:
The wireless STA of claim 18, wherein the processing system is further configured to cause the wireless STA to: (see claim 18) and The method of claim 29, further comprising: (see claim 29).
Lu in view of Wang discloses discloses utilizing a spatial reuse threshold but fails to explicitly recite an updated threshold value for spatial reuse communication mode and therefore fails to disclose “receive an indication of an updated threshold value associated with the selection between the spatial reuse communication mode or the multi-primary channel communication mode; and communicate using the spatial reuse communication mode or the multi-primary channel communication mode in accordance with the updated threshold value.”
In a related field of endeavor, Pandian discloses:
receive an indication of an updated threshold value associated with the selection between the spatial reuse communication mode or the multi-primary channel communication mode; and communicate using the spatial reuse communication mode or the multi-primary channel communication mode in accordance with the updated threshold value (Pandian, [0108] discloses In some implementations, the process 900 may be an example implementation of adjusting the PD threshold in block 708 of FIG. 7. At block 902, the first wireless communication device adjusts the PD threshold to increase a margin between the adjusted PD threshold and the determined RSSI value concurrently with maintaining the adjusted PD threshold higher than the level of OBSS interference. By increasing the margin between the adjusted PD threshold and the determined RSSI value such as by adjusting the PD threshold to a level that is less than the determined RSSI value by at least a configured amount, the first wireless communication device may ensure that it can detect and receive WLAN packets addressed or intended or for the first wireless communication device. Also, by maintaining the adjusted PD threshold higher than the level of OBSS interference on the wireless medium, the first wireless communication device may increase the likelihood of gaining medium access in the presence of OBSS traffic and may also increase the likelihood of collisions on the wireless medium; Pandian, [0112] discloses As described above, the OBSS PD threshold may govern the opportunities for spatial reuse SR transmissions, and the first wireless communication device may adjust the OBSS PD threshold based on whether a channel utilization of OBSS traffic is greater or less than a configured value. As such, if the channel utilization of OBSS traffic is greater than the configured value, the first wireless communication device may increase the likelihood of gaining medium access by increasing the OBSS PD threshold. Conversely, if the channel utilization of OBSS traffic is less than the configured value, the first wireless communication device may refrain from increasing the OBSS PD threshold for example, by maintaining the OBSS PD threshold or may decrease the likelihood of collisions on the wireless medium by decreasing the OBSS PD threshold; Pandian, [0127] discloses In some implementations, the first wireless communication device may, after determining that transmissions detected on the wireless medium are OBSS packets, determine RSSI values for the OBSS packets and compare the determined RSSI values with the adjusted OBSS PD threshold. When the RSSI values of the OBSS packets, which may correspond to the level of OBSS interference, is less than the adjusted OBSS PD threshold, the first wireless communication device may transmit data on the wireless medium using spatial reuse SR packets, even though there is another valid transmission on the wireless medium. When the RSSI values of the OBSS packets is greater than the adjusted OBSS PD threshold, the first wireless communication device may defer medium access; Pandian, [0116] discloses By increasing the OBSS PD threshold when the PER, the number of ACK timeouts, or the throughput loss is greater than the respective configured value, the first wireless communication device may increase the likelihood of obtaining a SR opportunity to transmit data to one or more other devices, which may reduce one or more of the PER, the number of ACK timeouts, or the throughput loss. Conversely, by maintaining the OBSS PD threshold when the PER, the number of ACK timeouts, or the throughput loss is less than the respective configured value, the first wireless communication device may maintain the likelihood of obtaining the SR opportunity, and thereby also maintain its transmit power levels for SR transmissions. Further, when decreasing the OBSS PD threshold when the PER, the number of ACK timeouts, or the throughput loss is less than the respective configured value, the first wireless communication device may increase its transmit power levels for SR transmissions and also decreasing the likelihood of obtaining SR opportunities. In some implementations, the OBSS PD threshold may be adjusted to increase a value of one or more of the performance metrics concurrently with increasing the number of SR transmission opportunities available to the first wireless communication device; Pandian, [0078] discloses For example, the MAC header 414 may include a combination of a source address, a transmitter address, a receiver address or a destination address. The MAC header 414 may further include a frame control field containing control information. The frame control field may specify a frame type, for example, a data frame, a control frame, or a management frame).
Therefore, at the time before the effective filing date of the invention, it would have been obvious to one of ordinary skill in the art to modify the invention of Lu in view of Wang to incorporate the teachings of Pandian for the purpose of providing the system with a means to ensure the wireless device is able to detect and receive WLAN packets addressed or intended or for the first wireless communication device and increase the likelihood of gaining medium access in the presence of OBSS traffic (Pandian, [0108]) and decrease the likelihood of collisions on the wireless medium (Pandian, [0112]) and for the purpose of making the system more dynamic and adaptable by providing the system with added functionalities and various different alternatives in design, thereby allowing the system to handle a number of various different combination of specific design structure and scenarios (Lu, [0138]) and thereby, preventing the system from being limited to a single specific design structure and scenario and furthermore, one of ordinary skill in the art would recognize based on the guidelines to rationales supporting a conclusion of obviousness seen on MPEP 2143, that the modification would involve use of a simple substitution of one known element and base device (i.e. performing spatial reuse based on a comparison between a received signal strength and a threshold as taught by Lu) with another known element and comparable device utilizing a known technique (i.e. performing spatial reuse based on a comparison between a received signal strength and a threshold, wherein the threshold is updated by increasing, decreasing or maintaining as taught by Pandian) to improve the similar devices in the same way and to obtain the predictable result of the system performing spatial reuse based on a comparison between a received signal strength and a threshold (i.e. as taught by both Lu & Pandian) and is dependent upon the specific intended use, design incentives, needs and requirements (i.e. such as due to teachings of a known standard, current technology, conservation of resources, personal preferences, economic considerations, etc.) of the user and the system as has been established in MPEP 2144.04.

A duration of a PBSR period may be set according to TXOP duration information or PPDU length information in the received OBSS frame; Lu, [0135]-[0136] discloses Additionally, process 2800 may involve processor 2712 designating a first primary channel of the plurality of primary channels as a current primary channel for the operating bandwidth with remaining one or more of the plurality of primary channels being one or more auxiliary primary channels.

Lu in view of Wang discloses discloses utilizing a spatial reuse threshold but fails to explicitly recite an updated threshold value for spatial reuse communication mode and therefore fails to disclose “a first frame including a receiver address indicative of a wireless communication device; update the threshold value by a delta value to a second threshold value in accordance with a failure to satisfy a criteria associated with reception, from the wireless communication device, of a second frame associated with the first frame; and communicate with the wireless communication device using the spatial reuse communication mode or the multi-primary channel communication mode in accordance with the second threshold value.”
In a related field of endeavor, Pandian discloses:
a first frame including a receiver address indicative of a wireless communication device; update the threshold value by a delta value to a second threshold value in accordance with a failure to satisfy a criteria associated with reception, from the wireless communication device, of a second frame associated with the first frame; and communicate with the wireless communication device using the spatial reuse communication mode or the multi-primary channel communication mode in accordance with the second threshold value (Pandian, [0108] discloses In some implementations, the process 900 may be an example implementation of adjusting the PD threshold in block 708 of FIG. 7. At block 902, the first wireless communication device adjusts the PD threshold to increase a margin between the adjusted PD threshold and the determined RSSI value concurrently with maintaining the adjusted PD threshold higher than the level of OBSS interference. By increasing the margin between the adjusted PD threshold and the determined RSSI value such as by adjusting the PD threshold to a level that is less than the determined RSSI value by at least a configured amount, the first wireless communication device may ensure that it can detect and receive WLAN packets addressed or intended or for the first wireless communication device. Also, by maintaining the adjusted PD threshold higher than the level of OBSS interference on the wireless medium, the first wireless communication device may increase the likelihood of gaining medium access in the presence of OBSS traffic and may also increase the likelihood of collisions on the wireless medium; Pandian, [0112] discloses As described above, the OBSS PD threshold may govern the opportunities for spatial reuse SR transmissions, and the first wireless communication device may adjust the OBSS PD threshold based on whether a channel utilization of OBSS traffic is greater or less than a configured value. As such, if the channel utilization of OBSS traffic is greater than the configured value, the first wireless communication device may increase the likelihood of gaining medium access by increasing the OBSS PD threshold. Conversely, if the channel utilization of OBSS traffic is less than the configured value, the first wireless communication device may refrain from increasing the OBSS PD threshold for example, by maintaining the OBSS PD threshold or may decrease the likelihood of collisions on the wireless medium by decreasing the OBSS PD threshold; Pandian, [0127] discloses In some implementations, the first wireless communication device may, after determining that transmissions detected on the wireless medium are OBSS packets, determine RSSI values for the OBSS packets and compare the determined RSSI values with the adjusted OBSS PD threshold. When the RSSI values of the OBSS packets, which may correspond to the level of OBSS interference, is less than the adjusted OBSS PD threshold, the first wireless communication device may transmit data on the wireless medium using spatial reuse SR packets, even though there is another valid transmission on the wireless medium. When the RSSI values of the OBSS packets is greater than the adjusted OBSS PD threshold, the first wireless communication device may defer medium access; Pandian, [0116] discloses By increasing the OBSS PD threshold when the PER, the number of ACK timeouts, or the throughput loss is greater than the respective configured value, the first wireless communication device may increase the likelihood of obtaining a SR opportunity to transmit data to one or more other devices, which may reduce one or more of the PER, the number of ACK timeouts, or the throughput loss. Conversely, by maintaining the OBSS PD threshold when the PER, the number of ACK timeouts, or the throughput loss is less than the respective configured value, the first wireless communication device may maintain the likelihood of obtaining the SR opportunity, and thereby also maintain its transmit power levels for SR transmissions. Further, when decreasing the OBSS PD threshold when the PER, the number of ACK timeouts, or the throughput loss is less than the respective configured value, the first wireless communication device may increase its transmit power levels for SR transmissions and also decreasing the likelihood of obtaining SR opportunities. In some implementations, the OBSS PD threshold may be adjusted to increase a value of one or more of the performance metrics concurrently with increasing the number of SR transmission opportunities available to the first wireless communication device; Pandian, [0078] discloses For example, the MAC header 414 may include a combination of a source address, a transmitter address, a receiver address or a destination address. The MAC header 414 may further include a frame control field containing control information. The frame control field may specify a frame type, for example, a data frame, a control frame, or a management frame)
