The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
Independent Claims
Claim(s) 1, 24, 25 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kneckt et al. “AP MLD Beaconing and Discovery”, Apple Inc, June 8, 2020, IEEE 802.11-20/865r0 in view of Kenny (US-20160050623), Park (US-20180020410), Naribole et al. “MLO Constraint Indication and Operating Mode”, Samsung, March 15, 2020, IEEE 802.11-20/0226r4.
As to claim 1, 24, 25: Kneckt teaches a method comprising: receiving, by a non-access point multi-link device (non-AP MLD) from an AP MLD, a multi-link element (slide12 1. A single Beacon carries a complete set of parameters of other APs in the same AP MLD, 2. A single Beacon carries a partial set of parameters of other APs in the same AP MLD, 3. A single Beacon carries basic info (e.g. RNR) and Check Beacon of other APs in the same AP MLD) in a beacon frame through a primary link (slide 15, 16, 18 beacon from AP received by non-AP MLD); and performing, by the non-AP MLD, a multi-link operation based on the multi-link element (slide 6 STA needs to discover at least one AP in AP MLD to initiate authentication and MLD Setup; slide 7 Once a Non-AP MLD discovers an AP MLD on one link, it may transmit a unicast ML Query management frame; slide 20 STA may query AP parameters in other links after the MLD Setup; slide 21The Check Beacon indicates whether STA should obtain the link specific AP parameters), wherein the AP MLD includes a first AP operating on the primary link and a second AP operating on a nonprimary link (slide 5, 6 multiple APs over different links), wherein the multi-link element included in the beacon frame includes information related to a specific update for the first AP of the AP MLD (slide 13 Check Beacon is one octet long field that is updated if a critical link specific AP parameter value changes),
Kneckt may not explicitly teach wherein the beacon frame is received only on the primary link. However, Kenny teaches wherein the beacon frame is received only on the primary link ([0022] In example embodiments, if the AP 102 transmits a beacon only on a primary channel).
Thus, it would have been obvious to one of ordinary skill in the art to implement beacons only on primary link, taught by Kenny, into the beacon, taught by Kneckt, in order to implement a well-known feature of a pre-defined protocol and reduce power consumption and overhead. In addition, it would have been obvious to combine Kneckt and Kenny in a known manner to obtain predictable results as the combination would not change the essence, quiddity, or functionality of the prior art references.
Although Kneckt already teaches critical updates, Kneckt may not explicitly teach and wherein at least one event including an event related a channel switch is classified as the critical update. However, Park teaches wherein at least one event including an event related a channel switch is classified as the specific update ([0064, 80, 88] The AP can update the value of the check beacon field when the beacon frame to be sent includes a channel switch announcement element).
Thus, it would have been obvious to one of ordinary skill in the art to implement channel switch announcement, taught by Kenny, into the critical update, taught by Kneckt (slide 13), in order to implement a well-known feature of a pre-defined protocol and allow STAs and APs to maintain communications on the new channel. In addition, it would have been obvious to combine Kenny and Kneckt in a known manner to obtain predictable results as the combination would not change the essence, quiddity, or functionality of the prior art references.
Kneckt may not explicitly teach and wherein a change of an operating channel for at least one of the primary link or the nonprimary link is supported for the AP MLD. However, Naribole teaches and wherein a change of an operating channel for at least one of the primary link or the nonprimary link is supported for the AP MLD (slide 17 AP MLD may switch the channel of a link over time to a new spectrum).
Thus, it would have been obvious to one of ordinary skill in the art to implement channel switching, taught by Naribole, into the AP MLD, taught by Kneckt, in order to implement a well-known feature of a pre-defined protocol and avoid interference. In addition, it would have been obvious to combine Kneckt and Naribole in a known manner to obtain predictable results as the combination would not change the essence, quiddity, or functionality of the prior art references.
Dependent Claims
Claim(s) 19, 20, 21 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kneckt et al. “AP MLD Beaconing and Discovery”, Apple Inc, June 8, 2020, IEEE 802.11-20/865r0 in view of Kenny (US-20160050623), Park (US-20180020410), Naribole.
As to claim 19: Kneckt teaches the method of claim 1, wherein: wherein the multi-link element included in the beacon frame further includes information related to the primary link and the nonprimary link (slide 5, slide 12 A single Beacon carries a complete set of parameters of other APs in the same AP MLD; slide 11 RNR includes all AP in other channels that belong to the same AP MLD, capabilities and operations of the reporting AP).
As to claim 20: Kneckt teaches the method of claim 19, wherein: the primary link and the nonprimary link are related to a nonsimultaneous transmit and receive (NSTR) AP MLD operation (slide 16 A STA MLD have STAs in power save and it may receive Beacons only from a single AP).
As to claim 21: Kneckt teaches the method of claim 1, wherein: the beacon frame further includes information related to a critical update for the second AP of the AP MLD (slide 13 Check Beacon is one octet long field that is updated if a critical link specific AP parameter value changes; slide 5, slide 7, slide 11: AP2 ).
Claim(s) 22 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kneckt, Kenny (US-20160050623), Park (US-20180020410), Naribole in view of Chitrakar et al. “Multi-link Element format”, Panasonic Corporation, May 2020, IEEE 802.11-20/0772r0
As to claim 22: Kneckt teaches the method of claim 1.
Kneckt may not explicitly teach wherein: the beacon frame further includes information related to a traffic identifier (TID)-to-link mapping. However, Chitraker teaches wherein: the beacon frame further includes information related to a traffic identifier (TID)-to-link mapping (slide 5, 6 TID-to-link mapping).
Thus, it would have been obvious to one of ordinary skill in the art to implement TID-to-link mapping, taught by Chitraker, into the WiFi communication, taught by Kneckt, in order to implement a well-known feature of a pre-defined protocol and enable multiple simultaneous connections. In addition, it would have been obvious to combine Chitraker and Kneckt in a known manner to obtain predictable results as the combination would not change the essence, quiddity, or functionality of the prior art references.
Claim(s) 23 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kneckt, Kenny (US-20160050623), Park (US-20180020410), Naribole in view of Patil (US-20190158413).
As to claim 23: Kneckt teaches the method of claim 1.
Kneckt may not explicitly teach wherein: the beacon frame further includes information related to an enablement or a disablement of at least one link. Patil teaches may not explicitly teach However, Patil teaches wherein: the beacon frame further includes information related to an enablement or a disablement of at least one link ([0004] Each AP periodically broadcasts beacon frames on the primary link to enable any STAs within wireless range of the AP to establish and maintain a communication link with the WLAN).
Thus, it would have been obvious to one of ordinary skill in the art to implement enabling WLAN links, taught by Patil, into the beacon, taught by Kneckt, in order to implement a well-known feature of a pre-defined protocol and enable user communication. In addition, it would have been obvious to combine Kneckt and Patil in a known manner to obtain predictable results as the combination would not change the essence, quiddity, or functionality of the prior art references.
