DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Arguments
Applicant's arguments filed 04/30/2026 have been fully considered but they are not persuasive. Examiner has thoroughly reviewed applicant’s arguments but firmly believes the cited reference to reasonably and properly meet the claimed limitations i.e. that transmitting, to the UE, a paging early indication (PEI) signal including an indication of a paging subgroup of the UE. Examiner respectfully direct the Application to paragraph 0105, Lyu et al where discloses that all UEs managed in a gNB DU cell group with a CU-DU distribution architecture may be divided into three subgroups: a subgroup 1, a subgroup 2, and a subgroup 3, and the three subgroups respectively correspond to the three service modes: the eMBB, the mMTC, and the URLLC. UEs in a cell also form different paged UE subgroups according to the service modes. Different paging management and processing units of the gNB paging corresponding UE subgroups: gNB DUs are implemented in two manners: Manner 1: One gNB DU classifies all user services into three service modes: the mMTC, the URLLC, and the eMBB. Internal paging management of the three service modes are respectively embodied in different paging processing units of the gNB, which respectively correspond to a paging processing unit 1, a paging processing unit 2, and a paging processing unit 3. Reference may be made to the schematic diagram of paging logic shown in FIG. 12. Manner 2: Three gNB DUs manage the three service modes, respectively, and all related paging processing is completed at the three gNB DUs; and all UEs in a cell group is also divided into three subgroups. Reference may be made to the schematic diagram of paging logic shown in FIG. 13-14.
In paragraphs 0025-0026, further, Nader et al discloses, gNB initiated paging, the gNB-Control Unit (CU) conveys the information to the gNB-Distributed Unit (DU). Control by the NW of PEI applicability area configured in a UE via dedicated configuration. An area e.g. RAN registration area, or a list of cells is configured in a dedicated message such as RRC Release to which the PEI transmission is applicable. In paragraphs 0168, 0228, Nader et al discloses, transmitting, to the wireless device, a message indicating that the wireless device is to monitor for PEI and/or WUS in the at least one last cell used by the wireless device.
Additionally, the examiner has given the claim language its broadest reasonable interpretation. Although the claims are interpreted in light of the specification, limitations from the specification are not read into the claims. See In re Van Geuns, 988 F.2d 1181, 26 USPQ2d 1057 (Fed. Cir. 1993). Applicant always has the opportunity to amend the claims during prosecution, and broad interpreted by the examiner reduces the possibility that the claim, once issued, will be interpreted more broadly than is justified. In re Prater, 415 F.2d 1393, 1404-05, 162 USPQ 541, 550-51 (CCPA 1969). One cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981); In re Merck & Co., Inc., 800 F.2d 1091, 231 USPQ 375 (Fed. Cir. 1986).

In the same field of endeavor, Ma et al discloses transmitting, to the UE, a paging early indication (PEI) signal including an indication of a paging subgroup of the UE (¶ 0127-0128, 0138, 0139 and 0151, UE capability or UE type. In some embodiments, the type of PEI detected by the UE is determined by the UE capability or UE type. In some embodiments, the type of PEI detected by the UE is determined by the UE capability. In some embodiments, the UE capability includes at least one of the following: the number of receiving antennas, the number of transmitting antennas, whether coverage enhancement is supported, and the maximum supported (downlink or uplink) bandwidth. In some embodiments, the type of PEI detected by the UE is determined by the UE capability or UE type. In some embodiments, the RedCap (Reduced Capability) UE detects the sequence-based PEI, the other common UEs detect the DCI-based PEI and ¶ 0235, a gNB central unit (gNB-CU), a gNB distributed unit (gNB-DU), a gNB-CU-CP (control plane), a gNB-CU-UP (user plane), a data network, a core network or a Radio Network Controller (RNC), and is not limited herein.). Therefore, before the effective filing date of the claim invention, it would have been obvious to one of ordinary skill in the art at the time the invention was made to modify the device of Lyu et al by specifically adding feature in order to enhance system performance to allows the wireless network node to determine whether to monitor a paging occasion or a group of paging occasions based on a number of wireless terminal sub-groups associated with the indication, so that the wireless terminals can be monitored in the DRX cycle in an efficient manner, thus reducing power consumption of the network node in a reliable manner as taught by Ma et al.
Regarding claim 15, Lyu et al discloses, a distributed unit (DU) of a distributed base station operating in a radio access network (RAN), the DU comprising processing hardware and configured to page a user equipment (UE) when a radio connection between the distributed base station and the UE is not active, including:

In this case, the F1AP paging message also carries the service mode indication and the target UE identity. The gNB DU triggers, based on the service mode indication carried in the F1AP paging message, a target paging processing unit corresponding to the service mode indication and based on paging from the core network, all UEs managed in a gNB cell group with a CU-DU fusion architecture may be divided into three subgroups, gNB DU classifies all user services into three service modes: the mMTC, the URLLC, and the eMBB. Different paging processing units in a gNB paging corresponding UE subgroups. Reference may be made to the schematic diagram of paging logic shown in FIG. 11. Internal paging management of the three service modes are respectively embodied in different paging processing units of the gNB, which respectively correspond to a paging processing unit 1, a paging processing unit 2, and a paging processing unit 3. Reference may be made to the schematic diagram of paging logic shown in FIG. 12. Manner 2: Three gNB DUs manage the three service modes, respectively, and all related paging processing is completed at the three gNB DUs; and all UEs in a cell group is also divided into three subgroups. Reference may be made to the schematic diagram of paging logic shown in FIG. 13), and
page the UE in accordance with whether the UE supports paging sub grouping (¶ 0102-0105, a gNB CU sends an F1AP paging message to a gNB DU.
