(Maleki: para. [0101-0102] network node 16 is further configured to configure the first WUS monitoring occasion for the first group of wireless devices 22 with at least a time offset relative to a first discontinuous reception, DRX, ON duration period. the network node 16 is further configured to configure downlink control information, DCI, addressed to the first group of wireless devices 22 where the DCI includes a bitmap where a first plurality of bits are configured to indicate whether to wake-up a first subgroup of the first group of wireless devices 22 and a second plurality of bits are configured to indicate whether to wake-up a second subgroup of the first group of wireless devices 22) Regarding claim 6, Maleki teaches the method of claim 1, wherein the occasion for the WUS is earlier from an occasion (WUS MOs before an ON duration) for monitoring a physical downlink control channel (PDCCH) (PDCCH monitoring occasion (MOs) during the next ON duration) triggered by the WUS by an offset (pre-determined amount of time), and (Maleki: para. [0112] wireless device 22 is configured, such as by such as via one or more of processing circuitry 68, processor 70, radio interface 62, signaling unit 32, etc., of the network node 16, with one or more WUS Monitoring Occasions (MOs), that occur a pre-determined amount of time (e.g., predefined quantity of X slots) before an ON duration of the wireless device 22. The WUS is based on a signal sent by the network node 16 to the wireless device 22 over PDCCH using an existing or a new DCI format. The wireless device 22, via processing circuitry 84 and/or monitoring unit 34, decodes the DCI. The wireless device 22 can use a receiver and/or radio interface 82 based on PDCCH decoding or other types of receiver, e.g., correlation based receivers. If the WUS is configured for waking up that wireless device 22 (specifically or as part of a group), the wireless device 22, via processing circuitry 84 and/or monitoring unit 34, monitors PDCCH at PDCCH monitoring occasion (MOs) during the next ON duration, or follows network/network node 16 configured/commanded actions upon detection of WUS (e.g., an aperiodic CSI report, scheduling a PDSCH through WUS, etc.)) wherein information on the offset (X slots) between the occasion for the WUS and the occasion for monitoring the PDCCH is included in the configuration information, (Maleki: para. [0127] a PDCCH based WUS is used at a predetermined time (e.g., X slots) before the ON duration to wake-up the wireless device 22. The network node 16 can configure such as via one or more of processing circuitry 68, processor 70, radio interface 62, signaling unit 32, etc., the wireless device 22 to monitor WUS in specific offsets before the ON duration, e.g., X slots before the ON duration where X may be an integer such as a positive integer and/or nonnegative integer) or the information on the offset (later time) is configured with the UE based on an identity (ID) (third RNTI) of the UE. (Maleki: para.

The WUS is based on a signal sent by the network node 16 to the wireless device 22 over PDCCH using an existing or a new DCI format. The wireless device 22, via processing circuitry 84 and/or monitoring unit 34, decodes the DCI. The wireless device 22 can use a receiver and/or radio interface 82 based on PDCCH decoding or other types of receiver, e.g., correlation based receivers. If the WUS is configured for waking up that wireless device 22 (specifically or as part of a group), the wireless device 22, via processing circuitry 84 and/or monitoring unit 34, monitors PDCCH at PDCCH monitoring occasion (MOs) during the next ON duration, or follows network/network node 16 configured/commanded actions upon detection of WUS (e.g., an aperiodic CSI report, scheduling a PDSCH through WUS, etc.)) wherein a stating symbol of the occasion for the WUS including the monitoring occasion (WUS monitoring occasion) is configured for the UE.

Regarding claims 18 – 20, Maleki teaches a base station in a wireless communication system, the base station comprising: a transceiver; and a controller coupled with the transceiver and configured to: (Maleki: Summary, Fig. 3, Fig. 8 and para. [0081] network node 16 via an external connection. The software 74 may be executable by the processing circuitry 68) and Maleki teaches all the limitations as discussed in the rejection of claims 15 – 17, and therefore apparatus claims 18 – 20, are rejected using the same rationales. 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. The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. Claim(s) 4 and 11 is/are rejected under 35 U.S.C. 103 as being unpatentable over Maleki in view of Vos et al. US 9681256 B2, hereinafter Vos. Regarding claim 4, Maleki teaches the method of claim 1, Maleki does not explicitly teach: wherein the configuration information further includes information on a timer associated with the WUS, and wherein the method further comprises: in case that the timer expires, identifying whether a system information block (SIB) received from the base station needs to be updated. Vos from the same or similar fields of endeavor teach: wherein the configuration information further includes information on a timer associated with the WUS, and wherein the method further comprises: in case that the timer expires, identifying whether a system information block (SIB) received from the base station needs to be updated. (Vos: col. 8 lines 2-3 UE is required to update SIBs due to expiry of a three-hour timer, and col. 10 lines 32-49 an explicit operation to update SIB information can then be executed upon expiry of the update window) Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to use the teaching of Shrestha in the method of Maleki. One of ordinary skill in the art would be motivated to do so for eNB then only transmits changes to the SIB information relative to that last acquisition, thereby reducing the amount of data to be transmitted. The use of an update window as described above may also be applied to this solution, for example so that a UE may be configured to wait until expiry of the update window before explicitly requesting a SIB refresh (Vos: col. 10 lines 32-62). Regarding claim 11, Maleki and Vos teach all the limitations as discussed in the rejection of claim 4, and therefore apparatus claim 11 is rejected using the same rationales. Claim(s) 5 and 12 is/are rejected under 35 U.S.C. 103 as being unpatentable over Maleki in view of Shrestha et al. US20200229095A1, hereinafter Shrestha. Regarding claim 5, Maleki teaches the method of claim 1, Maleki does not explicitly teach: wherein the configuration information includes first information on an offset for the WUS, and second information on a number of repetitions of the WUS, and wherein the WUS is repeatedly received from the base station within monitoring occasions included in the occasion for the WUS based on the first information and the second information. Shrestha from the same or similar fields of endeavor teach: wherein the configuration information includes first information on an offset for the WUS, (Shrestha: para. [0103-0104] UE 101 may be configured to apply a WUS offset to determine when UE 101 should begin PO monitoring. In some embodiments, the WUS offset may be provided to UE 101 as part of system information (e.g., in a SIB) from RAN node 111. Additionally, the WUS offset may include a period of time. As shown, UE 101 may determine when to begin PO monitoring by applying the WUS offset from the reception of the wake up indication (e.g., detecting the WUS)) and second information on a number of repetitions of the WUS, and wherein the WUS is repeatedly received from the base station within monitoring occasions included in the occasion for the WUS based on the first information and the second information. (Shrestha: para. [0043 & 0059 & 0104] RAN node 111 may estimate the number of repetitions to be used for UE 101, which may be based on how the design of the WUS repetitions are mapped to the coverage level. For example, sending the WUS for coverage level 1, may include repetition (Rmax)/16 repetitions, which may be part of system information. The RAN node may add this information in a UE paging coverage information message. Para. [0044] UE paging coverage information message that may be used by RAN node 111 to provide MME 121 with coverage information and/or a number of WUS repetitions for UE 101) Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to use the teaching of Shrestha in the method of Maleki. One of ordinary skill in the art would be motivated to do so for among the benefits of using groups to manage and control which UEs 101 are to monitor one or more POs is that resources may be re-used for different groups while the wake-up frequency (the frequency with which a particular UE 101 may wake up) could be reduced, thus improving UE power savings, while keeping the resource allocation low (e.g., air interface resources within the specified bandwidth) (Shrestha: para. [0119]). Regarding claim 12, Maleki and Shrestha teach all the limitations as discussed in the rejection of claim 5, and therefore apparatus claim 12 is rejected using the same rationales. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Please also PTO-892. Chen et al. US 20230388930 A1 in para. [0228] teaches Receiving a system information change indication, where the system information change indication is used to receive a notification by using the wake-up signal or the activation signal in the first state. [0229] (6) Enabling a second timer, and if the second timer expires.
