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) 1-7, 9, 10 ,13-18, 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Fehrenbach et al. (US2022/0078684 herein Feh) in view of Tao et al. (US20230164647).

said apparatus comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor ([0436] “Depending on certain implementation requirements, embodiments of the invention can be implemented in hardware or in software. The implementation can be performed using a digital storage medium”, [0438] “The apparatus described herein may be implemented using a hardware apparatus, or using a computer”), cause the apparatus at least to:
respond to receipt of a request for providing access for a user equipment to at least some of said plurality of cells ([0234] “cell 1 sends CHO configuration requests to the potential target cells cell 2-5, and receives CHO configuration acknowledgment messages 250 from the cells 2-5. After receiving the CHO acknowledgment messages 250, the configuration data 1100 is sent 140 to the UE 110”),

generating a message comprising information indicative of a plurality of configurations for said target cells, said information comprising information ([0167] “in the configuration request message 240, the serving source cell 310 may provide the full list of the sequential CHO and/or may provide only the relevant CHO information to each of the target cells 120, Examiner’s Note: provide only the relevant CHO information is not explicitly clear that it is the same as a one delta configuration indicating a change in configuration compared to a configuration for a previous cell).
Feh does not explicitly teach indicative of at least one delta configuration indicating a change in configuration of one cell compared to a configuration for a previous cell.
Tao teaches indicative of at least one delta configuration indicating a change in configuration of one cell compared to a configuration for a previous cell ([0205“In the present case as will become apparent from the below disclosure, the receiver of the UE can thus be exemplarily configured to at least partly perform one or more of receiving a delta common configuration indication, of receiving differing common configuration elements of the target”).

The implementation can be performed using a digital storage medium”, [0438] “The apparatus described herein may be implemented using a hardware apparatus, or using a computer”), cause the apparatus at least to:
generate a message for transmission to a user equipment connected to said at least one cell, said message comprising information indicative of a plurality of configurations for a plurality of target cells for said user equipment and an order in which said user equipment is predicted to access said target cells ([0167] “in the configuration request message 240, the serving source cell 310 may provide the full list of the sequential CHO and/or may provide only the relevant CHO information to each of the target cells 120, [0234] “cell 1 sends CHO configuration requests to the potential target cells cell 2-5, and receives CHO configuration acknowledgment messages 250 from the cells 2-5.

Feh does not explictly teach and at least one delta configuration indicating a change in configuration compared to a configuration for a previous cell in said order.
Tao teaches and at least one delta configuration indicating a change in configuration compared to a configuration for a previous cell in said order ([0205“In the present case as will become apparent from the below disclosure, the receiver of the UE can thus be exemplarily configured to at least partly perform one or more of receiving a delta common configuration indication, of receiving differing common configuration elements of the target”).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Feh to incorporate the teachings of Tao. One of ordinary skill in the art would have been motivated to make this modification in order to minimize resources usage during handover procedures.
Regarding claim 2, Feh teaches wherein said information further comprises a plurality of conditions corresponding to said plurality of target cells (Fig. 9 “1100”, [0167] “in the configuration request message 240, the serving source cell 310 may provide the full list of the sequential CHO and/or may provide only the relevant CHO information to each of the target cells 120, Examiner’s Note: provide only the relevant CHO information is not explicitly clear that it is the same as a one delta configuration indicating a change in configuration compared to a configuration for a previous cell); said apparatus being further configured to determine when one of said plurality of conditions becomes fulfilled for said apparatus ([0262] “In an embodiment the user equipment is configured to trigger 160 the conditional handover by sending a signal 160 to the target cell and complete 230, 350 the conditional handover by receiving a signal from the target cell”).

when one of said plurality of conditions becomes fulfilled for said apparatus whether a corresponding target cell corresponds to a cell that said apparatus is seeking to access and where not, to not apply said corresponding configuration ([0133] “For example, for terrestrial CHO, it is important, for example, that the CHO configuration is removed or deleted at some point in time. This is commonly done, for example, by explicit signalling from the cell or from the gNB of a cell, after expiry of a validity timer or, for example, after a successful, completed handover. In a regular procedure, the CHO configuration is removed or deleted (in step 4 on FIG. 2) after successful completion of the CHO”).
Regarding claim 5 Feh teaches wherein prior to applying said corresponding one of said configurations, said apparatus is configured to perform measurements to determine whether to connect to said corresponding target cell ([0041] “According to embodiments, the user equipment is configured to trigger an update of the configuration data from the serving cell by sending a report, e.g. a measurement report, to the actual serving cell and/or to a new serving cell”).

Regarding claim 9, Feh teaches wherein, said apparatus is configured in response to missing at least one target cell of said plurality of target cells in said predicted order by not accessing said at least one target cell ([0219] “For instance, the UE may be configured to perform a CHO at a specific or expected position and/or within a specified or expected time window to a specific target gNB or target cell. In case, for example, the UE passed the respective position and/or the respective time window and does not see the expected target cell or a different cell, e.g. cell 8, it may, for example, tell the source gNB, e.g. with a report or a measurement report and/or a CHO failure message, if it is still connected and/or may tell the new target gNB or new serving cell, e.g. after a RACH/Connection Setup procedure, that is already connected to, for example, that the CHO configuration was erroneous predicted or expected and/or that the CHO configuration or CHO configuration data might be needed to be updated”),
to construct an updated delta configuration for a cell subsequent to said at least one missed cell using a delta configuration of said at least one missed target cell, said updated delta configuration indicating a change in configuration compared to a most recently accessed cell ([0143] “As the UE 110 reaches cell 5, the UE 110 gets updated 320 by cell 5 with a CHO configuration update data 325 comprising further trigger conditions and configuration data of the handovers from cell 5 to cell 6 and from cell 6 to cell 7. The configuration update data 325 may comprise a new version or only a changed portion or a delta portion of the configuration data 1100”).

Regarding claim 13, Feh teaches wherein said serving network node comprises a terrestrial network (TN) node and comprises a master node providing a primary serving cell ([0133] “For example, for terrestrial CHO, it is important, for example, that the CHO configuration is removed or deleted at some point in time. This is commonly done, for example, by explicit signalling from the cell or from the gNB of a cell, after expiry of a validity timer or, for example, after a successful, completed handover”, [0021] “In case of asking for an addition of a conditional handover to the target cells the configuration data relates to, the network, or the currently serving cell, may send a new configuration data or update to the existing configuration to the UE. It is also possible that a normal handover is initiated where the serving cell prepares the handover to the non-yet anticipated target cell”, (Examiner’s Note: currently serving cell could be BRI as master node).
Regarding claim 14, Feh teaches wherein said serving network node comprises ([0021] “In case of asking for an addition of a conditional handover to the target cells the configuration data relates to, the network, or the currently serving cell, may send a new configuration data or update to the existing configuration to the UE. It is also possible that a normal handover is initiated where the serving cell prepares the handover to the non-yet anticipated target cell”, (Examiner’s Note: currently serving cell could be BRI as master node).
Feh does not teach a NTN node.
Tao teaches a NTN node ([0170] “the satellite payload implements frequency conversion and a Radio Frequency amplifier in both uplink and downlink direction. It corresponds to an analogue RF repeater. Hence, the satellite repeats the NR-Uu radio interface from the feeder link (between the NTN gateway and the satellite) to the service link (between the satellite and the UE) and vice versa. The Satellite Radio Interface (SRI) on the feeder link is the NR-Uu. In other words, the satellite does not terminate NR-Uu”).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Feh to incorporate the teachings of Tao. One of ordinary skill in the art would have been motivated to make this modification in order to minimize resources usage during handover procedures.
Regarding claim 15, Feh teaches wherein said apparatus is configured for single connectivity and said plurality of target cells are provided by at least one of the following: at least one TN node ([0133] “For example, for terrestrial CHO, it is important, for example, that the CHO configuration is removed or deleted at some point in time. This is commonly done, for example, by explicit signalling from the cell or from the gNB of a cell, after expiry of a validity timer or, for example, after a successful, completed handover”, [0021] “In case of asking for an addition of a conditional handover to the target cells the configuration data relates to, the network, or the currently serving cell, may send a new configuration data or update to the existing configuration to the UE. It is also possible that a normal handover is initiated where the serving cell prepares the handover to the non-yet anticipated target cell”, (Examiner’s Note: currently serving cell could be BRI as master node),
Feh does not teach at least one NTN node.
Tao teaches at least one NTN nodes ([0170] “the satellite payload implements frequency conversion and a Radio Frequency amplifier in both uplink and downlink direction. It corresponds to an analogue RF repeater. Hence, the satellite repeats the NR-Uu radio interface from the feeder link (between the NTN gateway and the satellite) to the service link (between the satellite and the UE) and vice versa. The Satellite Radio Interface (SRI) on the feeder link is the NR-Uu. In other words, the satellite does not terminate NR-Uu”).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Feh to incorporate the teachings of Tao. One of ordinary skill in the art would have been motivated to make this modification in order to minimize resources usage during handover procedures.
Regarding claim 16, Feh teaches wherein said apparatus comprises a UE ([0104] “The UE 110 informs the potential target node 120 as the RRC reconfiguration is completed by an RRC reconfiguration completed messages 270.”).
Regarding claim 18, Feh teaches wherein said information indicative of a plurality of configurations for said target cells comprises a full configuration for a first cell being visited ([0167] “in the configuration request message 240, the serving source cell 310 may provide the full list of the sequential CHO and/or may provide only the relevant CHO information to each of the target cells 120, Examiner’s Note: provide only the relevant CHO information is not explicitly clear that it is the same as a one delta configuration indicating a change in configuration compared to a configuration for a previous cell).
Feh does not teach and a delta configuration for subsequent cells, said delta configuration comprising a change in configuration compared to a previous cell.
Tao teaches and a delta configuration for subsequent cells, said delta configuration comprising a change in configuration compared to a previous cell ([0205“In the present case as will become apparent from the below disclosure, the receiver of the UE can thus be exemplarily configured to at least partly perform one or more of receiving a delta common configuration indication, of receiving differing common configuration elements of the target”).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified Feh to incorporate the teachings of Tao. One of ordinary skill in the art would have been motivated to make this modification in order to minimize resources usage during handover procedures.
Claim(s) 8, 11-12, 19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Feh in view of Tao further in view of Bergqvist et al. (US20250287283 herein after Berg).

Feh and Tao does not teaches configuration for a plurality of subsequent cells each comprising a delta configuration indicating a change in configuration compared to a configuration for a previous cell.
Berg teaches configuration for a plurality of subsequent cells each comprising a delta configuration indicating a change in configuration compared to a configuration for a previous cell ([0017] “a plurality of conditional reconfigurations from the RAN. Each conditional reconfiguration is associated with a mobility procedure, one or more candidate target cells, and an execution condition. These exemplary methods include storing the plurality of conditional reconfigurations”, [0135] “n some cases, the target RAN node may provide the configuration in a format that is relative or differential to the configuration of the source cell in which the UE currently operates. These are often referred to “delta configurations” and include only parameters of UE's configuration in the source cell that need to be modified for the corresponding target cell”).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the combination of Feh, Tao to incorporate the teachings of Berg. One of ordinary skill in the art would have been motivated to make this modification in order to facilitate a subsequent mobility procedure with low delay or latency.
Regarding claim 11, Feh does not teach wherein said apparatus is configured for dual connectivity and said plurality of target cells comprise secondary cells provided by at least one non-terrestrial network (NTN) node.
Tao teaches ([0169] “A non-terrestrial network (NTN) refers to a network, or segment of networks, using RF resources on board of a satellite, for instance. Exemplary, NTNs may comprise the following system elements: an NTN-capable terminal, which may refer to a 3GPP UE or a terminal that is specific to the satellite system in case a satellite does not serve directly 3GPP UEs”).

Each of the CGs is a group of serving cells that includes one MAC entity, a set of logical channels with associated RLC entities, a primary cell (PCell), and optionally one or more secondary cells (SCells). The term “special cell” (“SpCell” for short) refers to the MCG PCell or the primary SCG cell (PSCell) depending on whether the UE's MAC entity is associated with the MCG or the SCG, respectively. In non-DC operation (e.g., CA), SpCell refers to the PCell. An SpCell is always activated and supports physical uplink control channel (PUCCH) transmission and contention-based random access by UEs”).
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the combination of Feh, Tao to incorporate the teachings of Berg. One of ordinary skill in the art would have been motivated to make this modification in order to facilitate a subsequent mobility procedure with low delay or latency.
Regarding claim 12, Feh does not teach wherein said at least one NTN node comprises at least two NTN nodes.
Tao teaches wherein said at least one NTN node comprises at least two NTN nodes ([0170] “the satellite payload implements frequency conversion and a Radio Frequency amplifier in both uplink and downlink direction. It corresponds to an analogue RF repeater. Hence, the satellite repeats the NR-Uu radio interface from the feeder link (between the NTN gateway and the satellite) to the service link (between the satellite and the UE) and vice versa.
