Shows the spacing of the reference signals 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. Claims 2, 15, 16, and 17 are rejected under 35 U.S.C. 103 as being unpatentable over Liu et al. (US 20220053434 A1) or Liu in view of Wang et al. (US 20220014323 A1) or Wang. Claim 2 Liu fails to explicitly teach limitations of claim 2. However, Wang, in the same field of endeavor, teaches, (Original) The method of claim 1, wherein M=2, and N=1. (See Wang paragraph 0039, ...the CSI-RS for TRS is located in both the zeroth symbol and the second symbol in each time slot of an SS burst, so that the spectrum resource of a time slot can be occupied from the zeroth symbol, i.e. the starting symbol, of that time slot, and can further be occupied continuously by the CSI-RS for tracking in the second symbol.) Shows reference signal occupies 2 symbols spaced by 1 symbol Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling data of the claimed invention to combine receiving a reference signal occupying a number of symbols larger than zero and spaced apart by a number of symbols greater than or equal to zero as disclosed by Liu with reference signals occupying at least two symbols spaced by one symbol as disclosed by Wang to increase the efficiency of the system (i.e. to reduce the number of symbols to monitor). Claim 15 Liu fails to explicitly teach limitations of claim 15. However, Wang, in the same field of endeavor, teaches, (Currently Amended) The method of claim 5, wherein the first reference signal is a physical broadcast channel demodulation reference signal (PBCH DMRS), and the second reference signal is a secondary synchronization signal (SSS). (See Wang FIG. 2 [index 5] [PBCH DMRS], FIG. 2 [index 7] [PBCH DMRS]) Shows the first reference signal (See Wang FIG. 2 [index 6] [SSS]) Shows the second reference signal The motivation to combine Liu and Wang in the dependent claim consists of the same motivation as stated in claim 2. Claim 16 Liu fails to explicitly teach limitations of claim 16. However, Wang, in the same field of endeavor, teaches, (Original) The method of claim 1, wherein M=2, and N=3. (See Wang FIG. 2 [index 4] [PSS], FIG. 2 [index 8] [PSS]) Shows reference signal PSS occupying two symbols (See Wang FIG. 2 [index 5] [PBCH DMRS], FIG. 2 [index 6] [SSS], FIG. 2 [index 7] [PBCH DMRS]) Shows the three space symbols Shows reference signal occupies 2 symbols spaced by 3 symbols The motivation to combine Liu and Wang in the dependent claim consists of the same motivation as stated in claim 2. Claim 17 Liu fails to explicitly teach limitations of claim 17. However, Wang, in the same field of endeavor, teaches, (Original) The method of claim 16, wherein in a slot, symbol indexes of the first reference signal are 4 and 8, 5 and 9, 6 and 10, or 7 and 13, wherein a symbol index starts from 0.

Claims 3, 5, 8, 9, and 10 are rejected under 35 U.S.C. 103 as being unpatentable over Liu et al. (US 20220053434 A1) or Liu in view of Liu et al. (US 20210153146 A1) or Liu and Ji. Claim 3 Liu fails to explicitly teach limitations of claim 3. However, Liu and Ji, in the same field of endeavor, teaches, (Currently Amended) The method of claim 2, wherein in a slot, symbol indexes of the first reference signal are 2 and 4, 5 and 7, 8 and 10, or 11 and 13,.. (See Liu and Ji FIG. 3 [index 5] [DMRS/PSBCH], FIG. 3[index 7] [DMRS/PSBCH]) wherein a symbol index starts from 0; (See Liu and Ji FIG. 3 [index 0]) Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling data of the claimed invention to combine receiving a reference signal occupying a number of symbols larger than zero and spaced apart by a number of symbols greater than or equal to zero as disclosed by Liu with symbol indexes of a reference signal occupying indexes 5 and 7 and starting at index 0 as disclosed by Liu and Ji to increase the efficiency of the system (i.e. to reduce the amount of energy required to monitor for reference signals). Claim 5 Liu fails to explicitly teach limitations of claim 5. However, Liu and Ji, in the same field of endeavor, teach, (Currently Amended) The method of claim 2, wherein there is a second reference signal between two symbols of the first reference signal; wherein in a slot, … or the symbol indexes of the first reference signal are 5 and 7, and the symbol index of the second reference signal is 6;… (See Liu and Ji FIG. 3[index 5] [DMRS/PSBCH], FIG. 3[index 7] [DMRS/PSBCH]) Shows the first reference signal (See Liu and Ji FIG. 3[index 6] [SSS]) Shows the second reference signal The motivation to combine Liu, and Liu and Ji in the dependent claim consists of the same motivation as stated in claim 3. Claim 8 Liu fails to explicitly teach limitations of claim 8. However, Liu and Ji, in the same field of endeavor, teach, (Original) The method of claim 2, wherein in a slot, symbol indexes of the first reference signal are 3 and 5, 6 and 8, or 9 and 11, wherein a symbol index starts from 0. (See Liu and Ji FIG. 3[index 9] [DMRS/PSBCH], FIG. 3[index 11] [DMRS/PSBCH]) Shows the first reference signal (See Liu and Ji FIG. 3[index 0]) Shows the symbol index starts from 0 The motivation to combine Liu, and Liu and Ji in the dependent claim consists of the same motivation as stated in claim 3. Claim 9 Liu fails to explicitly teach limitations of claim 9. However, Liu and Ji, in the same field of endeavor, teach, (Currently Amended) The method of claim 2, wherein there is a second reference signal between two symbols of the first reference signal; …or the symbol indexes of the first reference signal are 9 and 11, and the symbol index of the second reference signal is 10, wherein a symbol index starts from 0. (See Liu and Ji FIG. 3[index 9] [DMRS/PSBCH], FIG. 3[index 11] [DMRS/PSBCH]) Shows the first reference signal (See Liu and Ji FIG. 3[index 10] [SSS]) Shows the second reference signal The motivation to combine Liu, and Liu and Ji in the dependent claim consists of the same motivation as stated in claim 3. Claim 10 Liu fails to explicitly teach limitations of claim 10. However, Liu and Ji, in the same field of endeavor, teach, (Currently Amended) The method of claim 2, wherein in a slot, symbol indexes of the first reference signal are 2 and 4, 3 and 5, 8 and 10, or 9 and 11, wherein a symbol index starts from 0,… (See Liu and Ji FIG. 3[index 9] [DMRS/PSBCH], FIG. 3[index 11] [DMRS/PSBCH]) Shows the first reference signal (See Liu and Ji FIG. 3[index 0]) Shows the symbol index starts from 0 The motivation to combine Liu, and Liu and Ji in the dependent claim consists of the same motivation as stated in claim 3. Claims 12 and 21 are rejected under 35 U.S.C. 103 as being unpatentable over Liu et al. (US 20220053434 A1) or Liu in view of Chuang et al. (WO 2018202088 A1) or Chuang. Claim 12 Liu fails to explicitly teach limitations of claim 12. However, Chuang, in the same field of endeavor, teaches, (Currently Amended) The method of claim 2, wherein indexes of resource elements (REs) occupied by the first reference signal in a resource block (RB) are 0, 4, and 8, wherein an RE index starts from 0, (See Chuang FIG. 2) PNG media_image1.png 693 879 media_image1.png Greyscale Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling data of the claimed invention to combine receiving a reference signal occupying a number of symbols larger than zero and spaced apart by a number of symbols greater than or equal to zero as disclosed by Liu with reference signals occupying a resource block with resource element or RE indexes of 0, 4, and 8 and the RE index starts at 0 as disclosed by Chuang to increase the efficiency of the system (i.e. to increase the accuracy of monitoring for reference signals in a resource block). Claim 21 Liu fails to explicitly teach limitations of claim 21. However, Chuang, in the same field of endeavor, teaches, (Currently Amended) The method of claim 16, wherein the first reference signal is a tracking reference signal (TRS). (See Chuang page 2 Summary paragraph 2, The method may also involve the processor receiving, from the base station, a TRS burst containing a plurality of TRS symbols with one or more com ponents of the UE configured according to the TRS configuration.) The motivation to combine Liu and Chuang in the dependent claim consists of the same motivation as stated in claim 12. Claims 18, 23 and 26 are rejected under 35 U.S.C. 103 as being unpatentable over Liu et al. (US 20220053434 A1) or Liu in view of Huang et al. (WO 2021056227 A1) or Huang. Claim 18 Liu fails to explicitly teach limitations of claim 18. However, Huang, in the same field of endeavor, teaches, (Currently Amended) The method of claim 16,… …or indexes of REs occupied by the first reference signal in an RB is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11, wherein an RE index starts from 0. (See Huang page 11 paragraph 5, l'represents the symbol index of the symbol in the PRS resource in the PRS resource. For example, l'=0 indicates the first symbol of the PRS resource. Among them, N represents the number of symbols contained in the PRS resource. For example, the value of N is 12 or 6. For example, the PRS resource occupies 12 consecutive or 6 consecutive symbols in 1 time slot.) Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling data of the claimed invention to combine receiving a reference signal occupying a number of symbols larger than zero and spaced apart by a number of symbols greater than or equal to zero as disclosed by Liu with a reference signal occupying at least two consecutive REs in a resource block or RB as disclosed by Huang to increase the efficiency of the system (i.e. to reduce the overhead required to conduct synchronization with reference signals). Claim 23 Liu fails to explicitly teach limitations of claim 23. However, Huang, in the same field of endeavor, teaches, (Currently Amended) The method of claim 22, wherein in a slot, symbol indexes of the first reference signal are 6, 7, 8, 9, 10, 11, 12, 13, wherein a symbol index starts from 0,… (See Huang FIG. 6) PNG media_image2.png 610 855 media_image2.png Greyscale The motivation to combine Liu and Huang in the dependent claim consists of the same motivation as stated in claim 18. Claim 26 Liu fails to explicitly teach limitations of claim 26. However, Huang, in the same field of endeavor, teaches, (Original) The method of claim 25, wherein in a slot, symbol indexes of the first reference signal are 4 and 5, 6 and 7, 8 and 9, or 10 and 11, wherein a symbol index starts from 0. (See Huang FIG. 6) PNG media_image3.png 571 807 media_image3.png Greyscale The motivation to combine Liu and Huang in the dependent claim consists of the same motivation as stated in claim 18. Claim 27 is rejected under 35 U.S.C. 103 as being unpatentable over Liu et al. (US 20220053434 A1) or Liu in view of Oh et al. (US 20190327696 A1) or Oh. Claim 27 Liu fails to explicitly teach limitations of claim 27. However, Oh, in the same field of endeavor, teaches, (Currently Amended) The method of claim 22, wherein the first reference signal is a secondary synchronization signal (SSS), and the first reference signal occupies 20 resource blocks (RBs). (See Oh paragraph 0125, A transmission bandwidth (12 RBs 305) of the PSS 301 and a transmission bandwidth (20 RBs 306) of the SSS (303) and the PBCH 302 are differently related.) (See Oh FIG. 3 [303] [SSS], FIG. 3[306] [20RB]) Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling data of the claimed invention to combine receiving a reference signal occupying a number of symbols larger than zero and spaced apart by a number of symbols greater than or equal to zero as disclosed by Liu with a secondary synchronization signal occupying 20 RBs as disclosed by Oh to increase the efficiency of the system (i.e. to reduce probability of missing a transmission by a base station). Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Li et al. (US 20190245728 A1) or Li teaches receiving phase noise compensation references signal and spacing apart orthogonal frequency division multiplexing or OFDM symbols receiving the references signals.
