And/or, if the configuration information is pre-defined/pre-configured, the corresponding relationship may be omitted… [0163] The UE may transmit a sounding reference signal (SRS) to the base station, in S3430. The UE may perform the SRS transmission operation based on the configuration information of the S3420.

In the current standard, it is defined that SRS transmission of 1, 2 and 4 ports is possible and all ports can be transmitted within a single symbol. Among various port multiplexing methods, a method of applying N-symbol based TDM and/or TD-OCC may be considered. The following shows several examples. [0122] E.g.1, TDM between 0/1/2/3 port (e.g., symbol #x) and 4/5/6/7 port (e.g., symbol #x+1) [0123] E.g.2, TD-OCC between 0/1/2/3 port (e.g., symbol #x) and 4/5/6/7 port (e.g., symbol #x+1)… [0124] [Issue #1] When supporting the above TDM and/or TD-OCC, clarification is required in standard techniques for the following problems…[0126] If the frequency hopping is configured and the TDM/TD-OCC is performed based on consecutive N symbols, clarification is needed in the current standard technique on how repetitionFactor should be applied. For example, if the TDM/TD-OCC is performed based on 2 consecutive symbols for a combination of nrofSymbols=10 and repetitionFactor=5, hopping occurs between a 5th symbol and a 6th symbol, so a frequency domain to be transmitted may vary. Thus, the 2 symbols to which the TDM/TD-OCC is applied may be transmitted in different frequency domains. Therefore, in the case of applying the TDM/TD-OCC even if the frequency hopping is performed, there is a need for a method capable of assuming the same frequency domain for consecutive N symbols to which the TDM/TD-OCC is applied. [0127] [Issue #2] When supporting the (TDM and/or) TD-OCC, clarification is required in standard techniques for the following problems…[0129] When the groupHopping or the sequenceHopping is configured and the (TDM/) TD-OCC is performed based on consecutive N symbols, clarification is needed as to whether hopping should be performed within a symbol interval to which the (TDM/) TD-OCC is applied. For example, when performing the group/sequence hopping, a base sequence may vary on a per symbol basis. Therefore, in the case of applying the TD-OCC even if the group/sequence hopping is performed, there is a need for a method capable of assuming the same base sequence for consecutive N symbols to which the TD-OCD is applied...”); and

Specifically, FIG. 14 illustrates a proposed method to which the following proposal #A2 is applied. [0151] Proposal #A2: (For the Issue #2) when applying (TDM/) TD-OCC for port multiplexing based on consecutive N symbols and performing group/sequence hopping, a method of performing the group/sequence hopping using a root index generated based on a specific symbol location within the N symbols…[0155] The above proposed methods (e.g., the proposal #A1/#A-a/#A1-1/#A2, etc.) may be applied independently and/or in combination.

In regards to claim 2, KIM (US 20250286679 A1) teaches the apparatus of claim 1, wherein the instructions are further executable by the at least one processor to cause the apparatus to: apply a different sounding reference signal sequence to each OFDM symbol of the plurality of sets of OFDM symbols in accordance with the sounding reference signal hopping scheme, wherein sequence hopping is enabled at the UE (See [Fig. 13] where a different sounding reference signal sequence (group #0, group #1, group #2, group#2) is applied to each of the OFDM symbols (#10, #11, #12, #13) of the plurality of sets of OFDM symbols, two sets of OFDM symbols comprising two symbols each, the first set being symbol #10 and symbol #11, the second set being symbol #12 and symbol #13. Also read, “[0149] FIG. 13 illustrates an example of SRS transmission performing group/sequence hopping in a system applicable to the present disclosure. Specifically, FIG. 13 illustrates a method based on the current standard. [0150] FIG. 14 illustrates an example of SRS transmission performing group/sequence hopping in a system applicable to the present disclosure. Specifically, FIG. 14 illustrates a proposed method to which the following proposal #A2 is applied. [0151] Proposal #A2: (For the Issue #2) when applying (TDM/) TD-OCC for port multiplexing based on consecutive N symbols and performing group/sequence hopping, a method of performing the group/sequence hopping using a root index generated based on a specific symbol location within the N symbols. [0152] In the above proposal, first/last/n-th symbol may be considered as an example of the “specific symbol location within the N symbols.” The specific symbol location may be defined between a base station and a UE by a fixed rule, or may be configured/indicated to the UE with a specific value based on L1/L2 signaling. The specific symbol location may be an example for performing the group/sequence hopping in units of N symbols to which the (TDM/) TD-OCC is applied, and does not limit the proposed methods. Therefore, it is obvious that the group/sequence hopping can be performed in units of the N symbols based on another index to apply the proposed methods. For example, it may be defined to perform the group/sequence hopping based on a certain index defined in units of the N symbols. [0153] In examples of FIGS. 13 and 14, nrofSymbols=4 and the group hopping were assumed. As illustrated in FIG. 13, based on the current standard, a group hopping operation may be performed on each symbol. On the other hand, as illustrated in FIG. 14, based on the proposed method, the group hopping operation may be performed based on a first symbol location in the N symbols. In this case, the same group may be applied within the N symbols. [0154] A base sequence of the same root index may be maintained within the N symbols bound by the port multiplexing. That is, in the current standard, the operation of performing the group/sequence hopping for each symbol may be performed in units of the N symbols to which the (TDM/) TD-OCC is applied through the proposal #A2.”)
In regards to claim 13, KIM (US 20250286679 A1) teaches the apparatus of claim 12, wherein a different sounding reference signal sequence is applied to each OFDM symbol of the plurality of sets of OFDM symbols in accordance with the sounding reference signal hopping scheme(See [Fig. 13] where a different sounding reference signal sequence (group #0, group #1, group #2, group#2) is applied to each of the OFDM symbols (#10, #11, #12, #13) of the plurality of sets of OFDM symbols, two sets of OFDM symbols comprising two symbols each, the first set being symbol #10 and symbol #11, the second set being symbol #12 and symbol #13.

Specifically, FIG. 14 illustrates a proposed method to which the following proposal #A2 is applied. [0151] Proposal #A2: (For the Issue #2) when applying (TDM/) TD-OCC for port multiplexing based on consecutive N symbols and performing group/sequence hopping, a method of performing the group/sequence hopping using a root index generated based on a specific symbol location within the N symbols. [0152] In the above proposal, first/last/n-th symbol may be considered as an example of the “specific symbol location within the N symbols.” The specific symbol location may be defined between a base station and a UE by a fixed rule, or may be configured/indicated to the UE with a specific value based on L1/L2 signaling. The specific symbol location may be an example for performing the group/sequence hopping in units of N symbols to which the (TDM/) TD-OCC is applied, and does not limit the proposed methods. Therefore, it is obvious that the group/sequence hopping can be performed in units of the N symbols based on another index to apply the proposed methods. For example, it may be defined to perform the group/sequence hopping based on a certain index defined in units of the N symbols. [0153] In examples of FIGS. 13 and 14, nrofSymbols=4 and the group hopping were assumed. As illustrated in FIG. 13, based on the current standard, a group hopping operation may be performed on each symbol. On the other hand, as illustrated in FIG. 14, based on the proposed method, the group hopping operation may be performed based on a first symbol location in the N symbols. In this case, the same group may be applied within the N symbols. [0154] A base sequence of the same root index may be maintained within the N symbols bound by the port multiplexing. That is, in the current standard, the operation of performing the group/sequence hopping for each symbol may be performed in units of the N symbols to which the (TDM/) TD-OCC is applied through the proposal #A2.”)
In regards to claim 3, KIM (US 20250286679 A1) teaches the apparatus of claim 2, wherein frequency resources for the sounding reference signal in the sounding reference signal resource are the same across OFDM symbols within a respective set of OFDM signals (See [Fig. 8] where frequency resources for the sounding reference signal in the sounding reference signal resource are the same across the OFDM symbols within the respective set of OFDM symbols, “[0135] In examples of FIGS. 7 and 8, nrofSymbols=8 and repetitionFactor=4 were assumed. As illustrated in FIG. 7, based on the current standard, a pattern of a single symbol in which all ports are defined may be repeatedly transmitted in repetitionFactor=4 times, and a frequency hopping operation may be performed at intervals of 4 symbols. On the other hand, as illustrated in FIG. 8, based on the proposed method, a pattern of 2 symbols in which all ports are defined may be repeatedly transmitted in repetitionFactor/N=2 times, and a frequency hopping operation may be performed at intervals of repetitionFactor=4 symbols.

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.
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.
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) 5, 6, 7, 8, 16, 17, 18, and 19, is/are rejected under 35 U.S.C. 103 as being unpatentable over KIM (US 20250286679 A1) in view of VIVO (“Further discussion on SRS enhancement”, cited in IDS received October 25, 2024)

If the proposed methods are applied in combination, signaling (e.g., L1/L2 signaling) for configuring/indicating a specific method may be introduced… [0160] The UE may receive configuration information related to the proposed methods (e.g., the proposals #A1/#A1-a/#A1-1/#A2, etc.) from the base station, in S3420. The configuration information may include all of configuration/indication based on L1/L2 signaling. And/or, if the configuration information is pre-defined/pre-configured, the corresponding relationship may be omitted… [0163] The UE may transmit a sounding reference signal (SRS) to the base station, in S3430. The UE may perform the SRS transmission operation based on the configuration information of the S3420. For example, the UE may perform the SRS transmission operation based on the proposed methods (e.g., the proposals #A1/#A1-a/#A1-1/#A2, etc.).”). The SRS transmission feature of KIM differs from that of claim 21, in that KIM is silent on receiving the sounding reference signal using the sounding reference signal resource in accordance with a power normalization factor that is based at least in part on the numerical quantity of antenna ports and the numerical quantity of OFDM symbols.
Despite these differences similar features have been seen in other prior art involving SRS transmission. FUTUREWEI (“FL Summary #1 on SRS enhancements”, see [section 3.2.3 Further details for TDMed SRS ports] under company “FL” ) suggests a feature for SRS transmission involving multiple antenna ports, which involves transmitting the SRS in accordance with a power normalization factor (i.e. number of antenna ports configured per symbol) that is based in part on a relationship between a numerical quantity of the multiple antenna ports and a numerical quantity of OFDM symbols, “Regarding the power control, in 38.213, we have: For SRS, a UE splits a linear value P ̂_("SRS" ,b,f,c) (i,q_s,l) of the transmit power P_("SRS" ,b,f,c) (i,q_s,l) on active UL BWP b of carrier f of serving cell c equally across the configured antenna ports for SRS. This may already cover the proper power scaling mentioned by the companies. For proponents of Enh. 1, is the intention here to clarify the understanding? E.g., is something like “… a UE splits … equally across the configured antenna ports for SRS on an OFDM symbol” sufficient?”
Thus, based upon the teachings of FUTUREWEI it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to modify the SRS transmission feature of KIM by adopting use of the power normalization factor seen in FUTUREWEI, in order to arrive at the apparatus of claim 21, in order to provide a benefit of SRS enhancement as recommended by the 3GPP standard.
