Claim Rejections - 35 USC § 103
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.
Claim(s) 1-7, 22-28 and 44-49 is/are rejected under 35 U.S.C. 103 as being unpatentable over Takeda et al. (US 2022/0247529) in view of Ingale et al. (US 2020/0053607, IDS Reference).
Regarding claims 1 and 22, Takeda et al. disclose a first device (Figure 1, UE 115; Figure 2, UE 215; Figure 9 and paragraph 152, a device 905 that supports temporary reference signal for fast SCell activation in accordance with aspects of the present disclosure. The device 905 may be an example of or include the components of a device 605, a device 705, or a UE 115 as described herein), comprising:
at least one processor (Figure 9, processor 940); and
at least one memory including computer program code (Figure 9, memory 930 including code 935);
wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the first device to:
receive, at a first device and via a first cell of a second device, an activation indication to activate a second cell of a third device (Figure 2, UE 215 receives SCell activation message from gNB 205 [second device] of PCell [first cell]. Base station 210 corresponds to third device of second cell [SCell]; Paragraph 104, Base station 205 may then transmit an SCell activation message to UE 215 indicating that base station 210 (e.g., the SCell) is to be activated in addition to the PCell (e.g., base station 205 in this example));
monitor a first set of reference signals from the second cell (Figure 2 and Paragraph 105, UE 215 may measure or otherwise perform AGC actions using the first portion of the aperiodic reference signal 220 transmitted from base station 210 in the slot(s) corresponding to the slot location);
determine, based on the first set of reference signal a downlink timing in the second cell (Paragraphs 4 and 46, The UE may then measure the aperiodic reference signals from the SCell(s) using the associated resources, e.g., in the first portion of aperiodic reference signal in slot n and the slot offset identifying slot n+k where the second portion of aperiodic reference signals are, which constitutes non-consecutive slots. This may enable to the UE to synchronize [determine timing] with the SCell in order to perform wireless communications more quickly and efficiently); and
measure a second set of reference signals from the second cell of the third device while performing activation of the second cell (Paragraph 105, UE 215 may measure or otherwise perform fine tuning (e.g., tracking) using the second portion of the aperiodic reference signal 220 transmitted from base station 210 in the slot(s) corresponding to the slot offset in relation to the slot location (e.g., during the second portion). Accordingly, UE 215 may transmit a CSI report to base station 210 indicating the results of the measurements in order to activate base station 210 as a SCell for UE 215).
Takeda et al. do not disclose the following limitations that are disclosed by Ingale et al.: measure a second set of reference signals while performing a random access procedure to the second cell (Ingale et al., Paragraph 85, CSI-RS set 2 of target cell 104b can also be received (328) from target cell 104b in RAR during the random access procedure) and starts measuring the CSI-RS resource while in parallel UE 102 initiates RACH; Claims 3 and 9, measuring received CSI-RS resource during the RACH procedure).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Takeda et al. with the cited disclosure from Ingale et al. in order to early alignment with the target cell (i.e. SCell) (Ingale et al., Paragraph 62).

wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the first device to measure the second set of reference signals by: measuring the second set of reference signals based on the measurement configuration (Paragraph 105, UE 215 may identify the slot location for the first portion of the aperiodic reference signal 220 for cell activation measurements and the slot offset between the first portion and the second portion of the aperiodic reference signal 220. For example, UE 215 may identify the slot location and the slot offset based on the SCell activation message transmitted from base station 205).

UE 215 may measure or otherwise perform fine tuning (e.g., tracking) using the second portion of the aperiodic reference signal 220 transmitted from base station 210 in the slot(s) corresponding to the slot offset in relation to the slot location (e.g., during the second portion). Accordingly, UE 215 may transmit a CSI report to base station 210 indicating the results of the measurements in order to activate base station 210 as a SCell for UE 215).
