The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 1-2, 5, 8-13, 15, 18-20, 22, 24, 28-32 is/are rejected under 35 U.S.C. 103 as being unpatentable over Liu US 20210282210 in view of Kneckt US 20220191786
1. A data transmission method, comprising:
sending, on a first link, by a first node, a request frame to a second node (Liu: [0036, 0045] Switch alerts 508, 514, 516 may be transmitted by either the AP 120A or the STA 110 and receiving device performs a corresponding action….the STA sends a switch alert to AP on link 2, the current link that about to become unavailable) in response to detecting that [[a]] the first link for data transmission between the first node and the second node currently does not satisfy a low delay data transmission requirement (Liu: [0041, 0045] determines that the link 2 will become unavailable for longer than the worst-case ELL latency (e.g., > 5ms)), so as to trigger the second node to determine a second link (Liu: [0036] the receiver acts on the alert. [0045] the switch is to “either link 1 or link 3” [0038] the switch to link 3), and adjust a power state of a target station on the second link from a power save mode to an active mode (Liu: [0038, 0041-0042] the wake-from-powered-off happens on the backup link), wherein the second link is a link satisfying the low delay data transmission requirement and comprised in other links except the first link and the other links are pre-established links for data transmission between the first node and the second node (Liu: [0044] the selected link supports ELL data rate. [0038] links 1-3 are already established), and
transmitting, by the first node, data to the second node on the second link (Liu: [0038]) wherein the transmitting, by the first node, data to the second node on the second link comprises: transmitting, by the first node, the data to the second node on the second link in response to receiving a first trigger frame from the second node, wherein the first trigger frame is used for indicating that the second node has determined the second link and has adjusted the power state of the target station on the second link to the active mode (Liu: [0038] after the switch, the STA sends an alert on link 3 “to indicate the STA is ready to receive communication”).
Liu merely discloses the term memory
Kneckt teaches the term memory (Kneckt: [0029] non-transitory memory)
Kneckt further teaches adjust a power state of a target station on the second link from a power save mode to an active mode (Kneckt: [0067-0068] PM=1 power save/PM=0 active. [0083] PM “changed from 1 to 0 …expedited link activation” [0075] per-link PM)
Kneckt further teaches transmitting, by the first node, data to the second node on the second link wherein the transmitting, by the first node, data to the second node on the second link comprises: transmitting, by the first node, the data to the second node on the second link in response to receiving a first trigger frame from the second node, wherein the first trigger frame is used for indicating that the second node has determined the second link and has adjusted the power state of the target station on the second link to the active mode (Kneckt: [0072, 0086] the STA sends a U-APSD trigger frame with PM=0, and then the AP transmit)
Thus, it would have been obvious to one skill in the art before the effective filing date of the claim invention to include the above recited limitation into Liu’s invention in order to coordinating activation and deactivation of multiple wireless links to obtain benefits of increased throughput and latency reduction while also reducing power consumption, as taught by Kneckt.
