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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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.
Claims 1-2, 27-28, 37-39 and 41-42 are rejected under 35 U.S.C. 103 as being unpatentable over Muru et al (US Publication No. 2024/0214142 A1)1 in view of Yang et al (US Publication No. 2021/0204155 A1) and further in view of Cirik et al (US Publication No. 2023/0180033 A1).
Regarding claim 1, Muru discloses, a user equipment (UE) for wireless communication [¶0119-0120, wireless device 22], comprising:
one or memories [FIG. 7; ¶0128, memory 88; note that every wireless device has at least one memory] (see also e.g., ¶0113 of US Provisional App. No. 63138733); and
one or more processors, coupled to the one or more memories [FIG. 7; ¶0128, processor 86 coupled to the memory 88; note that every wireless device has at least processor coupled to the memory] (see also e.g., ¶0113 of US Provisional App. No. 63138733), configured to:
select a set of radio link monitoring (RLM) reference signals . . . for selecting the set of RLM reference signals from among RLM reference signals that are quasi-colocated (QCLed) with active transmission control indicator (TCI) states [¶0119-0120, the wireless device 22 determines/selects at least one beam failure detection reference signal (BFD-RS) from at least one beam failure detection resource set, and each of the at least one BFD-RS being a quasi-colocation, QCL, Type D source RS in at least one of the at least two activated TCI states for at least one of the at least one CORESET] (see also e.g., ¶0104-0105 of US Provisional App. No. 63138733) for physical downlink control channel communications in one or more control resource sets (CORESETs) [¶0024, PDCCHs in CORESETs] (see also e.g., ¶0023 of US Provisional App. No. 63138733), wherein the one or more CORESETs include at least one CORESET with at least two active TCI states [¶0119-0120, the at least one CORESET includes at least two activated TCI states] (see also e.g., ¶0104-0105 of US Provisional App. No. 63138733), wherein the set of RLM reference signals is selected based on an . . . radio link quality [¶0022-0023 and 0155, the WD selects beam failure detection resource set q0 based on radio link quality] (see also e.g., ¶0020-0023 of US Provisional App. No. 63138733); and
monitor for the set of RLM reference signals [¶0119-0120, note that beam failure detection using a BFD-RS requires monitoring the BFD-RS; further see ¶0018, “For the purpose of BFD, the network configures the WD with BFD reference signals (synchronization signal block (SSB), channel state information reference signal (CSI-RS) or both SSB/CSI-RS resources), and the WD declares beam failure when the number of beam failure instance indications from the physical layer reaches a configured threshold before a configured timer expires”] (see also e.g., ¶0016 and 0104-0105 of US Provisional App. No. 63138733);.
Although Muru discloses, “select a set of radio link monitoring (RLM) reference signals . . . for selecting the set of RLM reference signals from among RLM reference signals” and “the set of RLM reference signals is selected based on an . . . radio link quality” as set forth above, Muru does not explicitly disclose (see, italicized and bold limitations), select a set of radio link monitoring (RLM) reference signals according to a rule for selecting the set of RLM reference signals from among RLM reference signals, and wherein the set of RLM reference signals is selected based on an average radio link quality calculated from a weighted average of respective radio link qualities of the RLM reference signals of one or more reference signal pairs of the set of RLM reference signals, each reference signal pair including a first RLM reference signal and a second RLM reference signal.
However, Yang discloses, select a set of radio link monitoring (RLM) reference signals according to a rule for selecting the set of RLM reference signals [¶0071, the beam group and/or cell with optimal signal strength and/or optimal signal quality for signal transmission (i.e., rule) is selected and an indication of the beam group or an indication of the cell is determined as the measurement result], and
wherein the set of RLM reference signals is selected based on an average radio link quality calculated from a weighted average of respective radio link qualities of the RLM reference signals of . . . the set of RLM reference signals [¶0069-0071, a beam group is indicated/selected based on measurement results of signal strength or quality (¶0071, “the measurement result may include information obtained by comparing or calculating the signal strength and/or the signal quality. For example, when the at least one beam belongs to multiple beam groups or multiple cells, signal strength and/or signal quality for signal transmission of the multiple beam groups or the multiple cells may be calculated at first, the beam group and/or cell with optimal signal strength and/or optimal signal quality for signal transmission is selected and an indication of the beam group or an indication of the cell is determined as the measurement result”; further see ¶0069, the signal strength or quality for the beam group may be average strength (or weighted average strength) and/or average signal quality (or weighted average quality) for all beams in the beam group].
It is noted that the above-mentioned feature is a known technique in the field Applicant's endeavor, e.g., telecommunication art.
It would have been obvious to one having ordinary skill in the art before the effective filing date to combine the system of Muru with "the above-mentioned known feature(s)" taught by Yang to reach the claimed invention as set forth above. Since one having ordinary skill in the art could have recognized that applying the known technique taught by Yang into the system of Muru would have yield predictable results and/or resulted in the improved system, such as e.g., improving link quality estimation by combining measurements from multiple signal instead of relying on a single source, such a modification (or application) would have involved the mere application of a known technique to a piece of prior art ready for improvement," the claim is unpatentable under 35 U.S.C. 103(a). Ex Parte Smith, 83 USPQ.2d 1509, 1518-19 (BPAI, 2007) (citing KSR v. Teleflex, 127 S.Ct. 1727, 1740, 82 USPQ2d 1385, 1396 (2007)).
Further, Muru in view of Yang does not explicitly disclose (see, italicized and bold limitations), the reference signals of which a weighted average is calculated is modified to be “one or more reference signals pairs” and “each reference signal pair including including a first reference signal and a second reference signal”.
However, Cirik discloses, wherein . . . an average radio link quality calculated from . . . average of respective radio link qualities of the RLM reference signals of one or more reference signal pairs of the set of RLM reference signals [¶0392, the wireless device may take/calculate/determine/compute, for the RLM of the cell, an average of the radio link qualities of the at least two reference signals. The wireless device may declare/detect/determine an RLF of the cell based on the average of the radio link qualities. The physical layer of the wireless device may indicate, to the higher layer of the wireless device, an IS/OOS based on the average of the radio link qualities. For example, the average of the radio link qualities may be equal to (the first radio link quality + the second radio link quality)/2], each reference signal pair including a first RLM reference signal and a second RLM reference signal [¶0391, the wireless device may measure/assess, for the RLM of the cell, a first radio link quality of the first reference signal (indicated by the first TCI state) of the at least two reference signals. The wireless device may measure/assess, for the RLM of the cell, a second radio link quality of the second reference signal (indicated by the second TCI state) of the at least two reference signals].

It would have been obvious to one having ordinary skill in the art before the effective filing date to combine the system of Muru in view of Yang with "the above-mentioned known feature(s)" taught by Cirik to reach the claimed invention as set forth above. Since one having ordinary skill in the art could have recognized that applying the known technique taught by Cirik into the system of Muru in view of Yang would have yield predictable results and/or resulted in the improved system, such as e.g., improving link quality estimation by combining measurements from multiple signal instead of relying on a single source, such a modification (or application) would have involved the mere application of a known technique to a piece of prior art ready for improvement," the claim is unpatentable under 35 U.S.C. 103(a).

Regarding claim 2, Muru in view of Yang and Cirik discloses, the UE of claim 1 as set forth above.
Muru discloses, wherein the set of RLM reference signals is a proper subset of the RLM reference signals that are QCLed with the active TCI states in the one or more CORESETs [¶0119-0120, note that the at least BFD-RS is a subset of the BFD-RS set].
