Claims 1, 3-18, 37, 39 and 41 are rejected under 35 U.S.C. 103 as being unpatentable over Astrom et al (US 2021/0092679) in view of Zhang et al (US 2023/0300786).
Regarding claim 1, Astrom et al discloses method (fig. 7, method) for determining a Paging Occasion (PO), (network node also knows (determining) the WUS-to-PO ratio of UEs, [0030], lines 5-6) comprising:
receiving a Wake Up Signal (WUS) sent by a base station (network node (e.g. eNB, gNB) transmits a WUS related to a paging message, to a wireless device (UE), [0030], lines 1-2);
determining a target PO according to at least the WUS (network node also knows the WUS-to-PO ratio of UEs in both DRX and eDRX. From this information, the network node may determine a suitable WUS timing in relation to the PO in which the paging message is scheduled to be transmitted, [0030], lines 5-7); and
wherein determining the target PO according to at least the WUS comprises at least one of (network node also knows the WUS-to-PO ratio of UEs in both DRX and eDRX. From this information, the network node may determine a suitable WUS timing in relation to the PO in which the paging message is scheduled to be transmitted, [0030], lines 5-7):
determining the target PO according to first position information and first offset information corresponding to the WUS; (when the UE is operating in DRX mode, in which case a UE may be configured with a 1-to-M configuration, the WUS timing (first offset information) is determined to be ahead of the m.sup.th PO out of M POs that corresponds to the PO for which the UE is instructed to read WUS. This m.sup.th PO, (m={1, . . . , M}) may be identified by the UE's IMSI number or by explicit signalling. In another embodiment, the timing is related to the PO location (first position information) in a paging or system frame or hyperframe. Furthermore, in the DRX mode case, the WUS timing is determined at a plurality (up to M−1) of POs ahead of the PO being allocated for the paging message to safeguard proper detection of the WUS, [0037], lines 1-6) or
