Claims 1-6 and 16-21 are rejected under 35 U.S.C. 103 as being unpatentable over International Pat. Pub. WO 2024030415 to Ping-Heng Kuo et al. with priority to provisional Pat. App. 63/370,392 field August 4, 2022 (hereinafter Kuo) in view of US Pat. Pub. 20240195539 to Xiawei Jiang (hereinafter Jiang).
Regarding claim 1, Kuo in view of Jiang teaches An apparatus for wireless communications at a user equipment (UE), (Kuo Fig. 2, UE 110) comprising: one or more processors (Kuo Fig. 2, processor 205);
one or more memories coupled with the one or more processors (Kuo Fig. 2, memory ; and
instructions stored in the one or more memories and executable by the one or more processors to cause the apparatus to (Kuo Fig. 2, and para. [0029] teach application executed by processor 205):
monitor a set of semi-persistent scheduling occasions associated with downlink transmissions from a network entity, (Kuo paras. [0042] –[0052] teach that UE 110 may be in an active mode of monitoring PDCCH to receive a dynamic downlink resource assignment on PDDCH when SPS occasions are impacted by certain aspects of XR traffic during cDRX operation. As shown in Fig. 5 illustrates set of SPS occasions 502 and 503 that are a “set” of SPS occasions related to the monitoring:

and
Kuo does NOT teach selectively performing or dropping a feedback transmission associated with the monitoring based at least in part on the overlap between the second subset of semi-persistent scheduling occasions and the inactive period of the discontinuous transmission cycle.
In the analogous art of 3GPP 5G wireless communications, Jiang teaches selectively performing or dropping (Jiang teaches in Fig. 5, below, “postponed” mapped to dropping) a feedback transmission associated with the monitoring based at least in part on the overlap between the second subset of semi-persistent scheduling occasions and the inactive period of the discontinuous transmission cycle. (Jiang para. [0025] teaches a PUCCH-1 and a PUCCH-2 and a HARQ process feedback of a downlink SPS, “However, the network device and the terminal device cannot remain consistent with understanding of when to start a downlink HARQ RTT timer, causing that an actual DRX activation time of the terminal device is inconsistent with a DRX activation time of the terminal device understood by the network device, so that data retransmission scheduling information of the downlink control channel of the terminal device fails to be received.” Examiner interprets the inconsistency of the DRX causing an overlap necessitating a postponement “dropping”. Jiang Fig. 5 teaches an overlap of PUCCH-2 mapped to “second subset” as overlapping an inactive period as taught in Jiang para. [0052] )

It would have been obvious to one of ordinary skill in the art to have combined Kuo and Jiang to teach overlaps between DRX and SPS occasions. Each of Kuo and Jiang are in the field of wireless communications and DRX and SPS UE transmissions and receptions. One of ordinary skill in the art would have been motivated to combine Kuo with Jiang in order to improve the reliability of data transmission as taught in Jiang para. [0026].
Regarding claim 2, the Kuo does NOT teach wherein the instructions to selectively perform or drop the feedback transmission are executable by the one or more processors to cause the apparatus to: drop the feedback transmission based at least in part on the overlap between the second subset of semi-persistent scheduling occasions and the inactive period.
In the analogous art of 3GPP 5G wireless communications, Jiang teaches drop the feedback transmission based at least in part on the overlap between the second subset of semi-persistent scheduling occasions and the inactive period. (Jiang teaches the semi-persistent scheduling occasions associated with PUCCH-1 and PUCCH-2 as SPS resources. Jiang para. [0063] teaches that “after the downlink HARQ process feedback of the terminal device is postponed, the terminal device may process the “downlink HARQ RTT timer” and/or the “downlink HARQ retransmission timer” of the HARQ process feedback based on the “first resource before the transmission time is postponed” and/or the “second resource after the transmission time is postponed” transmitted by the downlink HARQ process feedback.” Jiang para. [0025] teaches a PUCCH-1 and a PUCCH-2 and a HARQ process feedback of a downlink SPS, “However, the network device and the terminal device cannot remain consistent with understanding of when to start a downlink HARQ RTT timer, causing that an actual DRX activation time of the terminal device is inconsistent with a DRX activation time of the terminal device understood by the network device, so that data retransmission scheduling information of the downlink control channel of the terminal device fails to be received.” Examiner interprets the inconsistency of the DRX causing an overlap necessitating a postponement “dropping”. Jiang Fig. 5 teaches an overlap of PUCCH-2 mapped to “second subset” as overlapping an inactive period as taught in Jiang para. [0052] )

One of ordinary skill in the art would have been motivated to combined Kuo with Jiang in order to improve the reliability of data transmission as taught in para. [0026].
Regarding claim 3, Kuo does NOT specifically teach wherein the instructions to selectively perform or drop the feedback transmission are executable by the one or more processors to cause the apparatus to:
drop the feedback transmission based at least in part on a numerical quantity of semi-persistent scheduling occasions in the first subset of semi-persistent scheduling occasions overlapping with the active period of the discontinuous transmission cycle failing to satisfy a threshold.
In the analogous art of 3GPP 5G wireless communications, Jiang teaches drop the feedback transmission based at least in part on a numerical quantity of semi-persistent scheduling occasions in the first subset of semi-persistent scheduling occasions overlapping with the active period of the discontinuous transmission cycle failing to satisfy a threshold.

[0027]-[0028] and [0045] that a downlink HARQ timer of a HARQ process feedback is processed based on a first resource feedback being postponed, and/or a second resource feedback after the transmission time is postponed. The postponements occur due to the DRX timing as provided in paras. [0027]-[0028]. Therefore the number of quantity of postponed SPS occasions overlapping with DRX cycle was the basis for dropping the feedback. More specifically, para. [0025] teaches a numerical quantity of two PUCCH feedback occasions being postponed: “when a transmission time of a HARQ process feedback of a downlink SPS resource of the terminal device is postponed from the first resource (such as the PUCCH-1) to the second resource (such as the PUCCH-2), considering from the perspective of the terminal device, there are two available transmission resources at the transmission time position of the HARQ process feedback, and a time position at which the terminal device starts the downlink RTT timer may be a transmission end time position of the first resource or the second resource.” The number of related downlink SPS occasions generating the need for the two feedback occasions occur during the active phase of the DRX as shown in Fig. 2, below.

In the analogous art of 3GPP 5G wireless communications, Jiang teaches perform the feedback transmission based at least in part on the overlap between the first subset of semi-persistent scheduling occasions and the active period of the discontinuous transmission cycle, the feedback transmission performed after a last semi-persistent scheduling occasion. (Jiang teaches the semi-persistent scheduling occasions associated with PUCCH-1 and PUCCH-2 as SPS resources. Jiang para. [0063] teaches that “after the downlink HARQ process feedback of the terminal device is postponed, the terminal device may process the “downlink HARQ RTT timer” and/or the “downlink HARQ retransmission timer” of the HARQ process feedback based on the “first resource before the transmission time is postponed” and/or the “second resource after the transmission time is postponed” transmitted by the downlink HARQ process feedback.” The processing mode includes that the terminal device processes the “downlink HARQ RTT timer” of the HARQ process based on the “first resource before the transmission time is postponed” and/or the “second resource after the transmission time is postponed” transmitted by the downlink HARQ process feedback.)

(Jiang teaches in paras. [0022]-[0025] SPS occasions PUCCH-1 at time tx and PUCCH-2 at time ty as a set of scheduling occasions wherein PUCCH-2 is the last scheduled occasion, wherein the DRX activation time of the network is inconsistent with the DRX activation time of the terminal device causing a failure.)

Kuo teaches that SPS occasions 402 and 403 are part of a periodic SPS transmission and as shown, there is an interference with an active network transmission of packet 420 due to jitter. Kuo para. [0047] teaches “During cDRX operation, the UE 110 may be in a sleep mode when the base station 300 intends to send the dynamic downlink resource assignment”. Examiner maps the second subset to SPS occasion 403 which is involved in the interference.)

It would have been obvious to one of ordinary skill in the art prior to the effective date of the invention to combine Kuo with Deogun to teach the feedback in a second active period. Each of Kuo and Deogun are in the field of wireless communications. One of ordinary skill in the art would have been motivated to combine Kuo and Deogun in order to reliably transmit high priority transmissions as taught in Deogun para. [0006].
Regarding claim 23, Kuo does NOT teach The method of claim 22, wherein performing the feedback transmission is based at least in part on a numerical quantity of semi-persistent scheduling occasions in the first subset of semi-persistent scheduling occasions, a time offset between the uplink occasion and a start of the second active period, or both.
In the analogous art of 3GPP 5G wireless communications, Deogun teaches performing the feedback transmission is based at least in part on a numerical quantity of semi-persistent scheduling occasions in the first subset of semi-persistent scheduling occasions, a time offset between the uplink occasion and a start of the second active period, or both. (Deogun teaches in para. [0141] and Fig. 7 teaches that “To indicate the actual timing of HARQ feedback transmission (relative to PDSCH reception) to the UE 3 dynamically, base station 5 may select one of the N values for the delay, and transmit an indication of the selected value to the UE within the DCI that schedules the corresponding PDSCH.” Therefore, Deogun teaches a number N that is between the uplink and the start of an active period (feedback transmission).)
Claim 9-15 and 24-30 are rejected under 35 U.S.C. 103 as being unpatentable over Kuo in view of US Pat. Pub. 20240107444 to Liang Hu et al. (hereinafter Hu).

and
instructions stored in the one or more memories and executable by the one or more processors (Kuo para. [0030] operations performed) to cause the apparatus to:
selectively monitor, based at least in part on an active period of a discontinuous transmission cycle of a network entity, for a downlink control information message associated with activating or deactivating the discontinuous transmission cycle of a network entity, the downlink control information message comprising [[a group common]] downlink control information message; (Kuo teaches in para. [0059] monitoring PDCCH to “determine whether the UE 110 should start, restart or extend a particular timer configured to control the UE 110 to utilize an active mode of monitoring the PDCCH after the SPS occasion”. Kuo teaches that whether to activate or deactivate dynamically is configured by DCI in paras. [0076]-[0077].)
and communicate with the network entity according to the discontinuous transmission cycle based at least in part on the selectively monitoring. (Kuo teaches in Fig. 6 that the UE communicates with the network according to the dynamic active mode in block 625:

Kuo does NOT teach that the DCI is a group common DCI.
In the analogous art of 3GPP 5G wireless communications, Hu teaches the downlink control information message comprising a group common downlink control information message. (Hu teaches in para. [0017] a new design for a “group common DCI 2 format 7 (2_7) that allow a gNB to dynamically indicate to the UEs which DTX/DRX pattern it is using and which pattern it is using for RRC idle/inactive UEs.)
It would have been obvious to one of ordinary skill in the art prior to the effective date of the invention to have combined Hu and Kuo to teach a group common DCI. Each of Hu and Kuo are in the field of wireless communications and discontinuous transmissions and receptions. One of ordinary skill in the art would have been motivated to combine Hu and Kuo in order to reduce network energy based on DCI-based group common adaption for period signals such as SPS as taught in Hu para. [0113].
Regarding claim 10, Kuo in view of Hu, specifically Kuo teaches The apparatus of claim 9, wherein the instructions to selectively monitor are executable by the one or more processors to cause the apparatus to:
monitor for the downlink control information message during the active period of the discontinuous transmission cycle. (Kuo para. [0020]-[0021] teaches monitoring for during the active period of discontinuous transmission cycle “exemplary embodiments introduce techniques configured to ensure that the UE is in active mode of monitoring the PDCCH” to avoid a mismatch between packet arrival and UE active mode. Kuo para. [0034] teaches transmitting configuration information (DCI) triggering the UE 110 to enter or stay in active mode of monitoring.)
Regarding claim 11, Kuo in view of Hu, teaches The apparatus of claim 9, wherein the instructions to selectively monitor are executable by the one or more processors to cause the apparatus to:
monitor for the [[group common downlink control information]] message outside of the active period and during an inactive period of the discontinuous transmission cycle. (Kuo para. [0034] teaches transmitting configuration information (DCI) triggering the UE 110 to enter or stay in active mode of monitoring see Fig. 6, above.)
Kuo does NOT teach monitor for the [[group common downlink control information]] message.

Hu teaches in para. [0101] that a UE can be configured to monitor a specific DCI format depending on a desired mode, such as dynamic mode.)
It would have been obvious to one of ordinary skill in the art to combine Hu and Kuo to teach a group common DCI to affect monitoring for DTX/DRX. Each of Hu and Kuo are in the field of wireless communications and discontinuous transmissions. One of ordinary skill in the art would have been motivated to combine Hu and Kuo in order to achieve faster and more efficient modifications from active to inactive states and reconfigured cycles as taught in Hu para. [0008].
Regarding claim 12, Kuo in view of Hu, specifically Kuo, teaches The apparatus of claim 9, wherein the instructions to selectively monitor are executable by the one or more processors to cause the apparatus to:
refrain from monitoring for the downlink control information message during one or more monitoring occasions occurring outside of the active period and during an inactive period of the discontinuous transmission cycle. (Kuo teaches in para. [0019] that outside the scheduled time duration of DRX cycle the UE may have the opportunity to utilize a sleep mode and conserve power by “not actively monitoring PDCCH” for a DCI. Examiner notes that Kuo para. [0054] teaches that the messages received from the network include RRC, control information, MAC CEs “DCI and any combination thereof”.)
Regarding claim 13, Kuo in view of Hu, specifically Kuo, teaches The apparatus of claim 9, wherein the instructions are further executable by the one or more processors to cause the apparatus to:
receive a signal indicating that the UE is to refrain from monitoring for the downlink control information message during one or more monitoring occasions occurring outside of the active period and during an inactive period of the discontinuous transmission cycle. (Kuo para. [0037] – [0040] teaches that UE transceiver receives signals implementing a cDRX cycle wherein “Outside of an onDuration, the UE 110 may have an opportunity to utilize a sleep mode and conserve power by not monitoring PDCCH.” “The sleep mode relates to conserving power by discontinuing a continuous processing functionality relating to operations that enable the UE 110 to monitor PDCCH.”)
Regarding claim 14, Kuo does NOT teach The apparatus of claim 9, wherein the instructions are further executable by the one or more processors to cause the apparatus to:
transmit a UE capability message indicating support for activating or deactivating the discontinuous transmission cycle via the downlink control information message.
In the analogous art of 3GPP 5G wireless communications, Hu teaches transmit a UE capability message indicating support for activating or deactivating the discontinuous transmission cycle via the downlink control information message. (Hu teaches in para. [0055] and Fig. 2A, above, block 201 that the UE sends “assistance information” to the gNB that indicates “the UE’s ability to receive DRX or DTX patterns” to enable the gNB to gather information to enable the UE to receive in block 203 “group information” via DCI.)
It would have been obvious to one of ordinary skill in the art to combine Hu and Kuo to teach a group common DCI to affect monitoring for DTX/DRX. Each of Hu and Kuo are in the field of wireless communications and discontinuous transmissions. One of ordinary skill in the art would have been motivated to combine Hu and Kuo in order to achieve faster and more efficient modifications from active to inactive states and reconfigured cycles as taught in Hu para. [0008].
Regarding claim 15, Kuo does NOT teach The apparatus of claim 14, wherein the support comprises support for refraining from monitoring for the downlink control information message outside of the active period and during an inactive period of the discontinuous transmission cycle.
In the analogous art of 3GPP 5G wireless communications, Hu teaches support for refraining from monitoring for the downlink control information message outside of the active period and during an inactive period of the discontinuous transmission cycle. (Hu teaches in para. [0062] that the patterns enable dynamic DTX/DRX cycles to enable UEs to achieve network energy savings. Hu para. [0012] teaches that as a result of the scheme is that UEs “no longer need to continuously monitor” a PDCCH and can enter sleep mode when the gNB is asleep. )

Each of Hu and Kuo are in the field of wireless communications and discontinuous transmissions. One of ordinary skill in the art would have been motivated to combine Hu and Kuo in order to achieve faster and more efficient modifications from active to inactive states and reconfigured cycles as taught in Hu para.

(Kuo teaches in para. [0020] a UE entering an active mode of monitoring in accordance with the cDRX cycle. Further para. [0020] teaches using MAC and Layer 1 and Layer 2 signaling to trigger an active mode of monitoring during cDRX to enable dynamic downlink resource assignment receipting independently from other mechanisms. Examiner interprets the Layer 1 and Layer 2 signaling as downlink control messages.)
