Claims 1, 13 , 14, 26 are rejected under 35 U.S.C. 103 as being unpatentable over Strater et al. (US 20230127459A1) in view of Seok (US-20210377928-A1) here in referred to as Seok1 .
Regarding to claim 1 (currently amended), Strater teaches: a controller within a mesh network ([0001], states “a steering controller that determines signal strength associated with content streamed between the client devices and the gateway/extenders, and steers client devices to the content streaming device having improved wireless connectivity performance” and [0094] states “ Embodiments of the present disclosure implemented in a star network topology may include a mesh solution.” These paragraphs implies the role of the controller may implemented wireless networks including mesh networks) comprising at least a station (STA) associated with the controller ([0024] and Fig. 12 show an exemplary wireless network having an STA connected to a wireless gateway controller, as described in [0046], lines 4-7), the controller arranged to: set a plurality of received signal strength intensity (RSSI) thresholds respectively corresponding to a plurality of operating bands of the controller ([0049] and Table describe an example about how the controller can define band-specific RSSI thresholds to optimize the steering of client device (SAT) between different bands such as 2.4 GHz and 5 GHz, [0051], lines 8-11 and lines 16-21, describe how to weight the band and how the controller determine which AP to steer a target SAT to “the controller uses the network link metric table to determine which AP to steer a target STA to.” And “The RSSI link threshold is preferably a configurable setting.”), when an RSSI of the STA on at least one enabled link of the STA crosses one of the plurality of set thresholds ([ 0043], lines 4-10 states “Wi-Fi performance of client stations (STAs) connected to an AP are monitored by gateway firmware through a received signal strength indicator (RSSI) of current STA to AP association. Clients having a poor (low RSSI) AP or STA association are steered to a different AP that has adequate throughput capacity” which implies the RSSI of the SAT may monitored and evaluated as stated in [0049] “When an STA’s associated RSSI link to a particular AP is lower than a configurable value or threshold (e.g. -75 dBm), the GW controller may target that STA to be steered.” Table 1 shows the link metric can be estimated relative the measured band in a given device), performing a calculation to determine respective scores of all enabled links of the STA ([0049] and [0054], lines 3-5 states “he RSSI estimation process includes measured RSSI from other band + Band Weighing (described previously).“ and [0058] states “A client station STA preferably communicates with a plurality of communicable APs to obtain their received signal strength indication (RSSI) in dBm units, selecting an AP with lowest negative dBm value or highest signal strength to establish communication with the selected AP.” These parts indicates performing computation for the RSSI scores for all enabling links (link quality metrics), then compared with a predefined threshold (e.g., -75 dBm for poor signal quality), as shown in Table 1 and Fig. 4), according to the calculation ([0015], “FIG. 4 shows an STA communicating with adjacent APs to determine their RSSI and assess their suitability for AP steering or band steering, or both”, [0057], lines 1-4 states “The gateway controller, upon recognizing a low signal strength for a STA, preferably steers that STA from its currently associated AP to another AP with better link quality (RSSI value)”, and lines 14-22 states “ the gateway controller uses the AP link metric table to determine which AP to steer a target STA to, by eliminating APs with measured and/or estimated links with an RSSI below a configurable, acceptable quality threshold (e.g. -65 dBm). Additionally, the use of AP channel utilization, using an AP channel utilization table, preferably avoids steering an STA to an overly-utilized AP by further eliminating APs with channel utilizations over a configurable, acceptable value (e.g. 75%).” These sections describes how the controller determine the best/better link quality metrics),
Strater does not explicitly teach, but Seok1 teaches determining a best number of spatial streams (NSS) configuration of the STA comprising which antenna of the STA operate on which of the plurality of operating bands ([0035] describes that the SAT supports multi-link functionality to operate on different bands, as shown in Fig. 1. Figs. 3, 6, 9, [0035], lines 12-17 and [0051], states “ the STA MLD may utilize the Antenna Configuration Switch management frame to indicate, for each supported link, the combinations of EHT-MCSs and spatial streams that a STA (e.g., STA1 or STA2) in STA MLD supports for reception and the combinations that the STA supports for transmission” describe the optimal number of special streams configuration for the SAT that achieve extreme-high-throughput (EHT) multi-link dynamic antenna switching, according to the process as stated in [0009], lines 10-13 “In communicating with the multi-link dynamic antenna switching, the processor receive a transmission from the AP MLD and communicate with the AP MLD using an increased number of spatial streams in response to the receiving. “ This is also indicated in the Abstract, lines 3-6, which states “In response to receiving the transmission, the non-AP STA MLD communicates with the AP MLD using an increased number of spatial streams with multi-link dynamic antenna switching at the non-AP STA MLD” to achieve optimum solution as states in [0002], “to extreme-high-throughput (EHT) multi-link dynamic antenna switching in wireless communications”), and whether both antennas are configured on the same operating band or different operating band (Fig. 1 illustrates multiple antennas are configured to operates with different links, [0052] states “When channel utilization of each link is changed, STA MLD may change its antenna capabilities to the following: (a) R2 receive chains and T2 transmit chains on link 1, and (b) R1 receive chains and T1 transmit chains on link 2”, and claim 15 states “establishing a multi-link operation over a plurality of links between an access point (AP) multi-link device (MLD) and a non-AP station (STA) MLD which has a constraint on simultaneous transmission and reception (Tx/Rx) on a first link and a second link of the plurality of links; and responsive to a condition being met, changing an antenna configuration of the non-AP STA MLD with respect to one or more receive chains or one or more transmit chains of the non-AP STA MLD between the first link and the second link of the plurality of links.” These parts indicate that the multi antennas can operate in the same or different bands for flexibility [0002]. [0052], lines 1-6 illustrates the switching antenna configuration with the same AP MLD or different AP MLD) and setting the best NSS configuration ([0007] states “The method may also involve communicating with the AP MLD using an increased number of spatial streams with multi-link dynamic antenna switching at the non-AP STA MLD in response to the receiving.” And [0040] states “For the receive chains negotiation procedure, the MU-RTS Trigger may include a User Info field with a spatial stream (SS) Allocation/Random Access (RA)-Resource Unit (RU) Information subfield equal to a requested receive chains (or spatial streams).”and [0040], lines 22-26, [0045] states “ Additionally, the AP MLD may transmit to the STA MLD that enabled its multiple receive chains a PPDU up to the total supported Rx spatial streams of the STA MLD.” These parts indicate that a negotiation included to determine optimal NSS configuration, [0071], lines 7-11), and sending an action frame to the STA for informing the STA to update its NSS configuration ([0048] states “multi-link dynamic antenna switching may be enabled by sending a Multi-Link Dynamic Antenna Switching action frame in which a Multi-Link Dynamic Antenna Switching mode field is set to 1 (indicating “Enable”).” which implies sending the action frame for dynamic switching of antenna where the action frame updates the NSS set by signaling as stated “Alternatively, the STA MLD may explicitly signal its group addressed frame reception link (e.g., Link ID thereof) in the Multi-Link Dynamic Antenna Switching action frame.” [0051], lines 1-11 implies that the method allow the SAT to update its antenna configuration/NSS configuration by sending management frame, [0052], states “In this case, STA MLD may transmit to the AP MLD the Antenna Configuration Switch management frame to indicate the changed transmit and receive chains for each supported link (e.g., link 1 and link 2).’ Where the SAT can also send the management frame to indicate the changing in the antenna configuration, including NSS updates as stated in [0066], states “In such case a number of the multiple spatial streams may be up to a number of total supported spatial streams of the non-AP STA MLD for reception.” ), the action frame including the set best NSS configuration ([0074] illustrates the management frame /action frame may include extreme-high-throughput modulation and coding schemes and spatial streams which is determined based on best configuration as stated “In some implementations, the management frame may include an Antenna Configuration Switch management frame that indicates, for each of the first link and the second link: (i) a first combination of EHT-MCSs and spatial streams that each STA of a plurality of STAs in the non-AP STA MLD supports regarding reception, and (ii) a second combination of EHT-MCSs and spatial streams that each STA of the plurality of STAs in the non-AP STA MLD supports regarding transmission.”).
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified Strater to incorporate the teachings of Seok1 (in analogous art) by sending an action frame to the STA for informing the STA to update its NSS configuration, which including the set best NSS configuration to achieve extreme-high-throughput (EHT) multi-link dynamic antenna switching in wireless communications. (Seok1, [0002]).
Regarding claim 13 (original): Strater and Seok1 teach the controller of claim 1.
Strater further teaches wherein each RSSI threshold further comprises an offset ([0057], lines 4-13, the RSSI thresholds can include offsets. For example, when estimating the RSSI for a different band, an offset (referred to as "Band Weighting factor offset") is applied, when estimating 2.4 GHz RSSI from 5 GHz measurements and when estimating 5 GHz RSSI from 2.4 GHz measurements).
Regarding claim 14 (currently amended): Strater teaches a method for updating an NSS configuration of a STA associated with a controller within a mesh network ([0001], states “a steering controller that determines signal strength associated with content streamed between the client devices and the gateway/extenders, and steers client devices to the content streaming device having improved wireless connectivity performance” and [0094] states “ Embodiments of the present disclosure implemented in a star network topology may include a mesh solution.” These paragraphs implies the role of the controller may implemented wireless networks including mesh networks, [0024] and Fig. 12 show an exemplary wireless network having an STA connected to a wireless gateway controller, as described in [0046], lines 4-7) the method comprising: utilizing the controller to set a plurality of received signal strength intensity (RSSI) thresholds respectively corresponding to a plurality of operating bands of the controller ([0049] and Table describe an example about how the controller can define band-specific RSSI thresholds to optimize the steering of client device (SAT) between different bands such as 2.4 GHz and 5 GHz, [0051], lines 8-11 and lines 16-21, describe how to weight the band and how the controller determine which AP to steer a target SAT to “the controller uses the network link metric table to determine which AP to steer a target STA to.” And “The RSSI link threshold is preferably a configurable setting.”), when an RSSI of the STA on at least one enabled link of the STA crosses one of the plurality of set thresholds ([ 0043], lines 4-10 states “Wi-Fi performance of client stations (STAs) connected to an AP are monitored by gateway firmware through a received signal strength indicator (RSSI) of current STA to AP association. Clients having a poor (low RSSI) AP or STA association are steered to a different AP that has adequate throughput capacity” which implies the RSSI of the SAT may monitored and evaluated as stated in [0049] “When an STA’s associated RSSI link to a particular AP is lower than a configurable value or threshold (e.g. -75 dBm), the GW controller may target that STA to be steered.” Table 1 shows the link metric can be estimated relative the measured band in a given device), performing a calculation to determine respective scores of all enabled links of the STA ([0049] and [0054], lines 3-5 states “he RSSI estimation process includes measured RSSI from other band + Band Weighing (described previously).“ and [0058] states “A client station STA preferably communicates with a plurality of communicable APs to obtain their received signal strength indication (RSSI) in dBm units, selecting an AP with lowest negative dBm value or highest signal strength to establish communication with the selected AP.” These parts indicates performing computation for the RSSI scores for all enabling links (link quality metrics), then compared with a predefined threshold (e.g., -75 dBm for poor signal quality), as shown in Table 1 and Fig. 4), according to the calculation ([0015], “FIG. 4 shows an STA communicating with adjacent APs to determine their RSSI and assess their suitability for AP steering or band steering, or both”, [0057], lines 1-4 states “The gateway controller, upon recognizing a low signal strength for a STA, preferably steers that STA from its currently associated AP to another AP with better link quality (RSSI value)”, and lines 14-22 states “ the gateway controller uses the AP link metric table to determine which AP to steer a target STA to, by eliminating APs with measured and/or estimated links with an RSSI below a configurable, acceptable quality threshold (e.g. -65 dBm). Additionally, the use of AP channel utilization, using an AP channel utilization table, preferably avoids steering an STA to an overly-utilized AP by further eliminating APs with channel utilizations over a configurable, acceptable value (e.g. 75%).” These sections describes how the controller determine the best/better link quality metrics),
