Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Radisys et al., Redcap UE support over F1, R3-215916, 3GPP TSG RAN WG3 #114-e, Nov 1-11, 2021 (hereinafter Radisys) in view of US 20240373499 A1 (AGIWAL et al.)(hereinafter AGIWAL) in view of Ericsson, Running CR for the RedCap WI, R2-2111095, 3GPP TSG RAN2 Meeting #116-e, Nov 1-12, 2021 (hereinafter Ericsson 1) and in further view of Ericsson, Running CR for the RedCap WI, R2-2111097, 3GPP TSG RAN2 Meeting #116-e, Nov 1-12, 2021 (hereinafter Ericsson 2).
In re claims 1 and 20, Radisys discloses a method performed by a distributed unit (DU) (Section 8.7.1.1, line 1, “The purpose of the Paging procedure is used to provide the paging information to enable the gNB-DU to page a UE”) and a distributed unit (DU) in a wireless communication system (Fig. 8.7.1.2-1, “gNB-DU”), the DU comprising: a transceiver configured to transmit and receive a signal; and a controller configured to control the transceiver to:
receive, from a central unit (CU), a first paging message for a terminal (Fig. 8.7.1.2-1, section 8.7.1.1, page 5, line 1, “The gNB-CU initiates the procedure by sending a PAGING message”), wherein the first paging message comprises:
first information that comprises a first identifier of the terminal (page 6, section 9.2.6.1, lines 1-2, “This message is sent by the gNB-CU and is used to request the gNB-DU to page UEs. Direction: gNB-CU ➔ gNB-DU”. Page 7, table, row 5, “RAN UE Paging identity”);
second information derived from a second identifier of the terminal (Page 7, Table, row 3, “UE identity Index value”);
third information related to discontinuous reception (DRX) (Page 7, Table, row 7, “Paging DRX”); and
fourth information related to DRX (Page 7, Table, row 13, “Paging eDRX” (the paging message includes a RAN UE paging identity, a UE identity index value, paging DRX, and paging eDRX));
determine, based on the first paging message, a paging frame and a paging occasion; and
transmit, via a paging channel, a second paging message in the paging occasion of the paging frame, wherein in case that fifth information is comprised in the first paging message:
the paging frame is determined based on the second information and the third information; and
the paging occasion is determined based on the second information and the fourth information, and wherein the fifth information is related to a paging occasion index.
Radisys does not explicitly disclose DU comprising: a transceiver configured to transmit and receive a signal; and a controller configured to control the transceiver.
AGIWAL discloses DU comprising: a transceiver (Fig. 20:2010) configured to transmit and receive a signal ([0015], “The base station includes: a transceiver configured to transmit and receive a signal”); and a controller configured to control the transceiver (Fig. 20:2020, [0015], “a controller coupled with the transceiver”).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Radisys with AGIWAL to provide a system and method for paging monitoring and acquiring dedicated system information in a wireless communication system. The advantage of doing so is converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) to support in a variety of fields including smart home, smart building, smart city, smart car or connected cars, smart grid, health care, smart appliances and advanced medical services.
Radisys and AGIWAL do not explicitly disclose determine, based on the first paging message, a paging frame and a paging occasion, wherein in case that fifth information is comprised in the first paging message: the paging frame is determined based on the second information and the third information; and the paging occasion is determined based on the second information and the fourth information, and wherein the fifth information is related to a paging occasion index.
Ericsson 1 discloses determine, based on the first paging message, a paging frame and a paging occasion (Page 39, section 7, lines 3-7, “The paging frame (PF) and paging occasion (PO) for paging are determined by the following formulae: System frame number (SFN) for the PF is determined by: (SFN + PF offset) mod T = (T div N)*(UE_ID mod N), Index (i_s), indicating the index of the PO is determined by: i_s = floor (UE_ID/N) mod Ns”), wherein in case that fifth information is comprised in the first paging message: the paging frame is determined based on the second information and the third information; and the paging occasion is determined based on the second information and the fourth information, and wherein the fifth information is related to a paging occasion index (Page 39, lines 15-25, “A PO is a set of 'S*X' consecutive PDCCH monitoring occasions where 'S' is the number of actual transmitted SSBs determined according to ssb-PositionslnBurst in SIB1 and X is the nrofPDCCH-MonitoringOccasionPerSSB-InPO if configured or is equal to 1 otherwise. The [x*S+K]th PDCCH monitoring occasion for paging in the PO corresponds to the Kth transmitted SSB, where x=0, 1, ... ,X-1, K = 1,2, ... ,S. The PDCCH monitoring occasions for paging which do not overlap with UL symbols...WhenfirstPDCCH-MonitoringOccasionOfPO is present, the starting PDCCH monitoring occasion number of (i_s + 1)th PO is the (i_s + 1)th value of the firstPDCCHMonitoringOccasionOfPO parameter; otherwise, it is equal to i_s * S*X...”. Page 39, line 26, “A PO associated with a PF may start in the PF or after the PF”. Page 39, section 7, lines 3-7, “The paging frame (PF) and paging occasion (PO) for paging are determined by the following formulae: System frame number (SFN) for the PF is determined by: (SFN + PF offset) mod T = (T div N)*(UE_ID mod N). Page 39, lines 30-31, “The following parameters are used for the calculation of PF and i_s above: T: DRX cycle of the UE” (paging frame and paging occasion is determined based on UE identifier and DRX and their derivations)).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Radisys and AGIWAL with Ericsson 1 to provide a system and method for paging monitoring and acquiring dedicated system information in a wireless communication system. The advantage of doing so is converging a fifth generation (5G) communication system for supporting higher data rates and low latency and address issues with high frequency band utilization in 5G to support in a variety of fields including smart home, smart building, smart city, smart car or connected cars, smart grid, health care, smart appliances and advanced medical services.
Radisys, AGIWAL and Ericsson 1 do not explicitly disclose transmit, via a paging channel, a second paging message in the paging occasion of the paging frame.
Ericsson 2 discloses transmit, via a paging channel, a second paging message in the paging occasion of the paging frame (Figure 5.3.2.1-1, section 5.3.2.1: Paging, lines 1-2, “The purpose of this procedure is: to transmit paging information to a UE in RRC_IDLE or RRC_INACTIVE”. Section 5.3.2.3: Reception of the paging message by the UE, page 42, lines 1-5, “if the ue-Identity included in the PagingRecord matches the UE's stored fullI-RNTI: 3> if the UE is configured by upper layers ,with Access Identity 1: 4> initiate the RRC connection resumption procedure according to 5.3.13 with resumeCause set to mpsPriorityAccess” (a paging message including a full-RNTI is transmitted)).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to combine the teachings of Radisys and AGIWAL with Ericsson 1 and Ericsson 2 to provide a system and method for paging monitoring and acquiring dedicated system information in a wireless communication system. The advantage of doing so is converging a fifth generation (5G) communication system for supporting higher data rates and low latency and address issues with high frequency band utilization in 5G to support in a variety of fields including smart home, smart building, smart city, smart car or connected cars, smart grid, health care, smart appliances and advanced medical services.
In re claim 2, the combination discloses the method of claim 1, wherein Ericsson 1 discloses wherein the paging frame and the paging occasion are determined based on the second information and the third information in case that the fifth information is not comprised in the first paging message (Section 7, Page 39, lines 3-7; lines 30-31, “The PF and PO for paging are determined by the following formulae: system frame number (SFN) for the PF is determined by: (SFN + PF offset) mod T = (T div N)*(UE_ID mod N). The following parameters are used for the calculation of PF and i_s above: T: DRX cycle of the UE”).
In re claim 3, the combination discloses the method of claim 1, wherein Ericsson 1 discloses wherein the third information related to DRX comprises a terminal-specific DRX value configured by radio resource control (RRC) (Section 7, Page 39, lines 30-35, “The following parameters are used for the calculation of PF and i_s above: T: DRX cycle of the UE, T is determined by the shortest of the UE specific DRX value(s), if configured by RRC and/or upper layers”).
In re claim 4, the combination discloses the method of claim 1, wherein Ericsson 1 discloses wherein the fourth information related to DRX comprises a terminal-specific DRX value configured by upper layers (Section 7, page 39, lines 33-35, “T is determined by the shortest of the UE specific DRX value(s), if configured by RRC and/or upper layers”. Table on Page 3, row 2, “For RRC_IDLE UE, when eDRX is no longer than 10.24s, T is determined by IDLE eDRX cycle. When eDRX cycle is longer than 10.24s, during the CN PTW, T is determined by the shortest of UE specific DRX cycle, if configured by upper layer, and default paging cycle” (terminal specific DRX value configured by upper layers)).
In re claim 5, the combination discloses the method of claim 1, wherein Ericsson 1 discloses wherein the fifth information is comprised in the first paging message for the terminal in case that the terminal supports a same paging occasion in RRC_IDLE and in RRC_INACTIVE (Section 7, Page 38, lines 31-38; page 39, lines 1-7, “The UE may use Discontinuous Reception (DRX) in RRC IDLE and RRC INACTIVE state in order to reduce power consumption. The UE monitors one paging occasion (PO) per DRX cycle. A PO is a set of PDCCH monitoring occasions and can consist of multiple time slots ( e.g. subframe or OFDM symbol) where paging DCI can be sent (TS 38.213). One Paging Frame (PF) is one Radio Frame and may contain one or multiple PO(s) or starting point of a PO. In multi-beam operations, the UE assumes that the same paging message and the same Short Message are repeated in all transmitted beams and thus the selection of the beam( s) for the reception of the paging message and Short Message is up to UE implementation. The paging message is same for both RAN initiated paging and CN initiated paging. The UE initiates RRC Connection Resume procedure upon receiving RAN initiated paging. If the UE receives a CN initiated paging in RRC_INACTIVE state, the UE moves to RRC_IDLE and informs NAS”). Radisys also discloses page 1: reason for change, “SA2 has confirmed in LSin R3-214712 that eDRX cycles> 10.24s for RRC Idle and eDRX upto 10.24s for RRC Inactive can be supported for Redcap UEs. Hence Paging eDRX IE for Redcap UEs needs to be supported over F1 paging”).
In re claim 6, the combination discloses the method of claim 1, wherein Radisys discloses wherein the first identifier is a temporal identifier determined by the CU (page 6, section 9.2.6.1, lines 1-2, “This message is sent by the gNB-CU and is used to request the gNB-DU to page UEs.

In re claim 9, the combination discloses the method of claim 1, wherein Ericsson 2 discloses wherein the first identifier is indicated to the terminal in a Radio Resource Control (RRC) message that causes state transition from RRC_CONNECTED to RRC_INACTIVE (section 5.3.2.1, lines 1-2, “The purpose of this procedure is: to transmit paging information to a UE in RRC_IDLE or RRC_INACTIVE”. Section 5.3.2.3, “2> if the ue-Identity included in the PagingRecord matches the UE's stored fullI-RNTI: 3> if the UE is configured by upper layers With Access Identity 1: 4> initiate the RRC connection resumption procedure according to 5 .3 .13 with resumeCause set to mpsPriorityAccess”).

Page 39, line 1, “The UE initiates RRC Connection Resume procedure upon receiving RAN initiated paging” (discloses that DRX cycle is used by UE to go in Idle state for power consumption or vice versa). Radisys also discloses on Page 5, section 8.7.1.2, “The Paging DRX IE may be included in the PAGING message, and if present the gNB-DU may use it to determine the final paging cycle for the UE” (paging cycle is used by UE to transition from RRC_Connected to RRC_Inactive state for power consumption)).
