The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1, 15 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Shanmugaraju et al. (Pub. No. 2023/0156842 A1 hereinafter Shanmugaraju) in view of ETSI TS 137 340 V15.13.0 (2021-09) (“Universal Mobile Telecommunications System (UMTS)” hereinafter NPL), and further in view of Xu et al. (Pub. No. 2022/0007443 A1 hereinafter Xu).
Regarding claim 1, Shanmugaraju teaches “an apparatus for supporting multiple bearers for a user equipment (UE)” as [(Para. 0003), With the 5G New Radio (5G-NR) wireless interface standard, 5G user equipment (UE) can support dual-connectivity (DC) split-bearer configurations that simultaneously utilize both 5G and LTE radio bearers…. (Para. 0019), With the eNodeB 103 and gNodeB 101 operating in parallel to establishes dual-connectivity with the UEs 108, the UEs 108 benefits from parallel communication links via the LTE primary cell group 112 and the 5G NR secondary cell group 110 for accessing the wireless services of the core network 130] “perform, upon detecting an addition of a secondary node in the communication network” [(Para. 0032), an eNodeB coupled to the at least one CU-UP, wherein the eNodeB comprises one or more radio points (RPs) configured as a second cell group to establish a second radio link for communicating with user equipment (UE) within the wireless coverage area].
However, Shanmugaraju does not specifically disclose with a limited Logical Channel Identifier (LCID) in a communication network, the apparatus configured to: determine a configuration mode of a bearer to be added for the UE, wherein the configuration mode is one of main cell group (MCG) mode and Secondary Cell Group (SCG)-split mode; allocate a LCID to the bearer based on the configuration mode of the bearer and one or more criteria; check whether LCIDs are available for allocating corresponding bearers requiring SCG-split mode in response to the addition of the secondary node; selectively assign the LCIDs to the corresponding bearers requiring the SCG-split mode, when the LCIDs are available for the bearers; and selectively switch a set of bearers, among the bearers, into the SCG-split mode when the LCIDs are available only for the set of bearers.
In an analogous art, NPL teaches “the apparatus configured to: determine a configuration mode of a bearer to be added for the UE, wherein the configuration mode is one of main cell group (MCG) mode and Secondary Cell Group (SCG)-split mode;” as [(Page 10, Section 4.2.2), , three bearer types exist: MCG bearer, SCG bearer and split bearer] “allocate a LCID to the bearer based on the configuration mode of the bearer and one or more criteria” [(Page 11, Section 4.2.2.-2), for SRB1 and SRB2 the logical channels are always configured at least in the MCG… each bearer (MCG, SCG and split bearer) can be terminated either in MN or in SN.].
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to modify the teachings as in Shanmugaraju to provide an effective technique as taught by NPL to utilise resources provided by two different nodes connected via non-ideal backhaul, one providing NR access and the other one providing either E-UTRA or NR access [NPL: Section 4.1.1].
However, the combination of Shanmugaraju and NPL does not specifically disclose with a limited Logical Channel Identifier (LCID) in a communication network; check whether LCIDs are available for allocating corresponding bearers requiring SCG-split mode in response to the addition of the secondary node; selectively assign the LCIDs to the corresponding bearers requiring the SCG-split mode, when the LCIDs are available for the bearers; and selectively switch a set of bearers, among the bearers, into the SCG-split mode when the LCIDs are available only for the set of bearers.
In an analogous art, Xu teaches “with a limited Logical Channel Identifier (LCID) in a communication network;” as [(Para. 0126), In the example, the bearer suggestion format may include a logical channel identifier (LCH-ID) ]“check whether LCIDs are available for allocating corresponding bearers requiring SCG-split mode in response to the addition of the secondary node;” [(Para. 00117), The MN may transmit an RRC configuration (e.g., reconfiguration) message to the UE, e.g., indicating that the SCG bearer configuration includes a logical channel (LCH) mapped on to NR FR1 cell(s) (1240). The RRC reconfiguration message may be an example of the transmission of configuration information described above with respect to 806. The UE may communicate with the SN using NR FR1 (1250).] “selectively assign the LCIDs to the corresponding bearers requiring the SCG-split mode, when the LCIDs are available for the bearers;” [(Para. 0007), The network may select bearer configurations including a range of values for a split bearer parameter based on the information, and may transmit an indication of the selected bearer configuration to the UE, e.g., if the selected bearer configuration is used for uplink transition by the UE. The UE may exchange data with the network using the selected bearer configuration and dynamically adjusting the split bearer parameter within the range of values. In addition, the network may also select a downlink bearer configuration based on the UE transmitted information and may exchange data with the UE using the selected downlink bear configuration … (Para. 0126), the bearer suggestion format may include a logical channel identifier (LCH-ID), bearer type, split bearer threshold (note that additional or different split bearer parameters may be included, e.g., an offloading ratio)] “and selectively switch a set of bearers, among the bearers, into the SCG-split mode when the LCIDs are available only for the set of bearers” [(Para. 0126), the bearer suggestion format may include a logical channel identifier (LCH-ID), bearer type, split bearer threshold (note that additional or different split bearer parameters may be included, e.g., an offloading ratio)… (Para. 0007), The UE may exchange data with the network using the selected bearer configuration and dynamically adjusting the split bearer parameter within the range of values.].
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to modify the teachings as in Shanmugaraju and NPL for negotiating bearer types and bearer type configurations based on information or measurements of the UE. [NPL: See Abstract].

Regarding claim 2, the combination of Shanmugaraju, NPL and Xu, specifically Xu teaches “wherein allocating the LCID to the bearer based on the configuration mode of the bearer comprises: selectively allocate a LCID from a second range of LCIDs determined based on the one or more criteria, when the configuration mode is the SCG-split mode” as [(Para. 0126), the bearer suggestion format may include a logical channel identifier (LCH-ID), bearer type, split bearer threshold (note that additional or different split bearer parameters may be included, e.g., an offloading ratio)… (Para. 0007), The UE may exchange data with the network using the selected bearer configuration and dynamically adjusting the split bearer parameter within the range of values.].
However, the combination of Shanmugaraju, NPL and Xu does not specifically disclose selectively allocate a LCID from a first range of LCIDs determined based on the one or more criteria, when the configuration mode is the MCG mode.
In an analogous art, Chen teaches “selectively allocate a LCID from a first range of LCIDs determined based on the one or more criteria, when the configuration mode is the MCG mode” as [(See Abstract), wherein the LCIDs of the logical channel corresponding to the each RB in the same group are different… (Page 8), Distribution module, be used for a plurality of radio bearer RB of via node RN equipment correspondence are divided at least two groups].
Therefore, it would have been obvious to one of ordinary skills in the art before the effective filing date of the claimed invention to modify the teachings as in Shanmugaraju, NPL and Xu for improvement the assignment logic channel number and definite logic channel in order to when the service dispatching, makes the logic channel of each the RB correspondence after receiving terminal can be determined to expand [Chen: Page 7-8].
Regarding claim 3, the combination of Shanmugaraju, NPL, Xu and Chen, specifically Chen teaches “select a range from the LCID-3 to LCID-6 when LCIDs are reserved for bearer type switching” as [(Page 8), The corresponding relation of RB sign and Logic Channel Identifier is set up in described base station, and wherein Logic Channel Identifier comprises logical channel number LCID and logic channel group id] “wherein the limited LCIDs available for the UE in the communication network is LCID-3 to LCID-10,” [(See Abstract), The corresponding relation of RB sign and Logic Channel Identifier is set up in described base station, and wherein Logic Channel Identifier comprises logical channel number LCID and logic channel group id;] “and wherein the first range of LCIDs is determined based on the one or more criteria by: select a range from the LCID-3 to LCID-8 when the LCIDs are unreserved for the bearer type switching;” as [(Page 8), Distribution module, be used for a plurality of radio bearer RB of via node RN equipment correspondence are divided at least two groups, be the different group id of each set of dispense, and be the logical channel assignment logical channel number LCID of each RB correspondence in each group, the LCID difference of the logic channel of each RB correspondence in wherein same group] “and select a range from the LCID-3 to LCID-10 when the LCIDs are unreserved for the bearer type switching and a maximum four LCIDs are required at a time” [(Page 8), Distribution module, be used for a plurality of radio bearer RB of via node RN equipment correspondence are divided at least two groups, be the different group id of each set of dispense, and be the logical channel assignment logical channel number LCID of each RB correspondence in each group, the LCID difference of the logic channel of each RB correspondence in wherein same group].

However, the combination of Shanmugaraju, NPL and Xu does not specifically disclose perform, upon determining whether a LCID is available from the second range of LCIDs, at least one of: when the LCID is available, allocate the LCID available from the second range; and when the LCID is unavailable, allocate a LCID from the first range of LCIDs.
In an analogous art, Chen teaches “perform, upon determining whether a LCID is available from the second range of LCIDs,” as [(), LCID can identify the logic channel of each RB correspondence,] “at least one of: when the LCID is available, allocate the LCID available from the second range; and when the LCID is unavailable, allocate a LCID from the first range of LCIDs” [(), Because the embodiment of the invention not on the same group the LCID of logic channel can be identical, as long as the quantity of the logic channel of each group is not more than the quantity of available LCID, after RB is expanded, only need the quantity of increase group, the quantity that just can guarantee current LCID satisfies the demand after the RB expansion].
