Consider claim 5, Huang discloses that the indication is sent on the link configured to receive the groupcast frames (see paragraph 181, where it is implicit that the DTIM is sent on the link configured to receive the groupcast frames).
Consider claims 14 and 21, Huang discloses to receive an indication from the access node apparatus indicating a suggested link to receive groupcast frames among the multiple links between the apparatus and the access node apparatus; and configure the suggested link to receive the groupcast frames (see paragraph 182: At block 908, the device may perform an action based on whether the non-AP MLD sent an indication that a first link of the plurality of links is selected by the non-AP MLD for receiving a first group addressed frame from the one or more group addressed frames).
Consider claim 18, Huang discloses to configure the access node of the access node apparatus to send the groupcast frames (see figures 3A, 3B, and 9, wherein disclosed is said configuring of the access node to send the groupcast frames).
Claim Rejections - 35 USC § 103
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.
Claims 4, 6-8, 16, 20, 23, and 25 are rejected under 35 U.S.C. 103 as being unpatentable over Huang (USPAN 2020/0396568) in view of Asterjadhi (USPAN 2016/0219522).
Consider claims 4 and 20, although Huang discloses the one or more other links configured to receive the groupcast frames or to abstain from receiving the groupcast frames are between other stations of the apparatus and other access nodes of the access node apparatus (see figures 3A, 3B, and 9, wherein disclosed is said configuring of the link to receive the groupcast frames), Huang does not specifically disclose that the station is in power save mode.
Asterjadhi discloses that the station is in power save mode (see paragraphs 68, 143, and 146: the station is in power save mode and is a station of a non-access node apparatus).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the invention of Huang and combine it with the noted teachings of Asterjadhi. The motivation to combine these references is to provide a method for triggered target wake time operation, to thereby save energy (see paragraph 3 of Asterjadhi).
Consider claim 6, although Huang discloses the indication (see above), Huang does not specifically disclose that the indication is comprised in a control field of a medium access control header.
Asterjadhi discloses that the indication is comprised in a control field of a medium access control header (see paragraph 65: “a subfield in the MAC header (e.g., within the high efficiency (HE) variant of the high throughput (HT) Control field) of a frame transmitted to the TWT responder may indicate a suspension of the TWT agreement(s) if set to 1 and may indicate a resumption of the TWT agreement(s) if set to 0, or vice versa”).
