Response to Amendment
The Amendment filed on 7/20/2026 has been entered.
Response to Remarks/Arguments
Applicant’s remarks/arguments (page 7-11), filed on 7/20/2026, with respect to claims 1-2 and 11 have
been fully considered but are not persuasive.
Regarding remarks in page 8, for independent claim 1, applicant asserts that the cited portions and Yoo in general disclose methods and patterns for SRS transmission with frequency hopping. However, Yoo is entirely silent on RB level frequency hopping across different symbols, where each symbol is a single unit of a time resource, in the manner recited by claim 1.
Examiner respectfully disagrees with the applicant. YOO et al. (US 2020/0077398 Al) discloses “Generally, an eNB broadcasts cell-specific SRS configuration information for UEs within a cell and transmits UE-specific SRS configuration information to a dedicated UE. Thus, the UE may determine the subframe area for transmitting SRS based on the configuration information. an eNB transmits cellspecific SRS configuration information to a UE. For example, the cell-specific SRS configuration information may be transmitted in an SIB or an RRC message. The UE (e.g., advanced UE) may identify a cell-specific subframe for SRS transmission based on the cell-specific SRS configuration information, Yoo: [0071]-[0072]. FIG. 6 is a diagram illustrating a resource grid for explaining SRS transmission with frequency hopping. Referring to FIG. 7, both the UE1 and UE2 transmit the SRS over the entire band across two symbols so as to achieve a gain of 3 dB as in the method of FIG. 6. Here, the two UEs use different time-orthogonal codes so as to perform estimation without interference with each other. FIG. 7 is a diagram illustrating a resource grid for explaining SRS transmission with time domain orthogonal covering codes (OCC), Yoo: Fig.6~7, [0022], [0073]-[0080]”.

Regarding remarks in page 9, for independent claim 11, applicant asserts that Yoo discloses that parameters for transmitting the SRS may be provided to the UE either in an RRC message or by a DCI format, with an RRC message being a preferable alternative (cf. paragraph [0135]). Yoo in view of Huang and Cha are entirely silent on determining a first slot offset for SRS transmission from DCI that is usable to adjust a second slot offset previously configured by RRC signaling, in the manner recited. Making this even more clear, Yoo teaches that either RRC or DCI may be used as two alternative methods for providing SRS transmission parameters, but is silent on DCI that is usable to adjust a slot offset that was previously configured by RRC signaling, in the manner recited by claim 11.
YOO et al. discloses “The frequency hopping pattern may be notified to the UE dedicatedly via an RRC message or DCI. The parameters necessary for transmitting the SRS may be transmitted to the UE in an RRC message or DCI format. 'srs-Configindex-Ap-rlO' denotes an SRS transmission subframe index for acquiring the trigger type 1 period and offset information; srs-ConfigApDCI-Format4-r10, srs-ConfigApDCI-FormatO-rlO, and srs-ConfigApDCIFormatlalb2c-310 are SRS configuration information to be used for the respective DCI formats triggering the transmission. if the extended RRC message is received, the UE transmits SRS in the extended area and there is a need to use srs-ConfigindexAp-rl0 in a different way. In this case, it is necessary to adjust the SRS periodicity and subframe offset to match with the subframe index to transmit the trigger type 1 SRS transmission, Yoo: [0073]-[0080], [0101], [0135], [0169], [0180]. the SRS periodicity and offset value corresponding to the SRS configuration index (ISRS) may be determined according to the table of FIG. 10. Yoo: Fig. 10, [0090]-[0095]. the srs-SubframeConfig is a cell-specific parameter transmitted to the UE using the SIB or RRC message, Yoo: [0101]”.
Regarding remarks in page 10, for dependent claim 2, applicant asserts that while Huang teaches to precode multiple SRSs differently and select a best precoding for a UE to use, in Huang the UE selects only the single precoding signaled by the eNB and is silent on a UE transmitting a single SRS over multiple symbols with multiple different precoders, in the manner recited by claim 2.
HUANG et al. (US 2018/0097595 Al) discloses “UE may further listen for additional signaling from the eNB identifying other precoding that the UE should use for transmitting data in the PUSCH. eNB may configure the UE to sound multiple SRS (e.g., over different symbols as an example), each SRS with a different precoder. eNB may measure the differently precoded SRS over different symbols. the UE may set the precoder for the SRS to be the same as the whitening matrix (e.g., the interference plus noise measured at the UE) for the UE., Huang: [0028]-[0029], [0042] - [0046]”.
Claim Objections
6. Claim 25 is objected to because of the following informalities:
Claim 25, in line 1, “The method of claim 14,” should be replaced by “The method of claim 11,”. Claim 14 has been canceled.
Appropriate correction is required.

unpatentable over HUANG et al. (US 2018/0097595 Al, hereinafter “Huang”) in view of YOO et al. (US 2020/0077398 Al, hereinafter “Yoo”) and in further view of CHA et al. (US 2022/0263621 Al, hereinafter “Cha”).
Regarding claim 1, Huang discloses:
A method, comprising:
(a) transmitting the SRS over different respective subcarriers in at least two symbols across the specified number of symbols, wherein for each of the at least two symbols the SRS occupies at least two subcarriers (Each subframe may include consecutive time slots, such as two. A resource grid may be used to represent two time slots, each time slot including a resource block (RB). resource block may contain 12 consecutive subcarriers in the frequency domain, Huang: Fig. 5A~5C, [0072]-[0080]).
Huang does not explicitly disclose:
transmitting a sounding reference signal (SRS) using a resource that comprises a specified number of symbols, wherein each symbol of the specified number of symbols comprises a single unit of a time resource, wherein transmitting the SRS comprises:
wherein the SRS occupies every Nth subcarrier in one or more resource blocks (RBs) of each symbol of the at least two symbols, wherein N is selected from a set comprising 2, 4, and 8; and
(b) transmitting the SRS using RB level frequency hopping across different symbols using one or more different respective RBs in the at least two symbols across the plurality of symbols,
However, in the same field of endeavor, Yoo teaches:
transmitting a sounding reference signal (SRS) using a resource that comprises a specified number of symbols, wherein each symbol of the specified number of symbols comprises a single unit of a time resource, wherein transmitting the SRS comprises (FIG. 6 is a diagram illustrating a resource grid for explaining SRS transmission with frequency hopping. Referring to FIG. 7, both the UE1 and UE2 transmit the SRS over the entire band across two symbols so as to achieve a gain of 3 dB as in the method of FIG. 6. Here, the two UEs use different time-orthogonal codes so as to perform estimation without interference with each other. FIG. 7 is a diagram illustrating a resource grid for explaining SRS transmission with time domain orthogonal covering codes (OCC), Yoo: Fig.6~7, [0022], [0073]-[0080]):
wherein the SRS occupies every Nth subcarrier in one or more resource blocks (RBs) of each symbol of the at least two symbols, wherein N is selected from a set comprising 2, 4, and 8 (Referring to FIG. 7, both the UE1 and UE2 transmit the SRS over the entire band across two symbols so as to achieve a gain of 3 dB as in the method of FIG. 6. Here, the two UEs use different time-orthogonal codes so as to perform estimation without interference with each other. the parameters added to the legacy configuration information include Number-of-combs indicating the number of combs (subcarrier pattern type for SRS transmission). transmissionComb-rl3 indicating comb type (subcarrier pattern for SRS transmission), and cyclicShiftr13 for supporting the cyclic shift up to 12. For example, Number-of-combs may indicate 2 combs supported in the legacy system or 4 combs supported newly, Yoo: Fig.6~7, Fig.14, [0022], [0073]-[0080], [0143]); and
(b) transmitting the SRS using RB level frequency hopping across different symbols using one or more different respective RBs in the at least two symbols across the plurality of symbols (FIG. 6 is a diagram illustrating a resource grid for explaining SRS transmission with frequency hopping, Referring to FIG. 7, both the UE1 and UE2 transmit the SRS over the entire band across two symbols so as to achieve a gain of 3 dB as in the method of FIG. 6. Here, the two UEs use different time-orthogonal codes so as to perform estimation without interference with each other. the parameters added to the legacy configuration information include Number-of-combs indicating the number of combs (subcarrier pattern type for SRS transmission). the UE may be allocated consecutive symbols to transmit the SRS over the channels of the entire band in a frequency hopping pattern, Yoo: Fig.6~7, Fig.14, [0022], [0073]-[0080]),
Therefore, 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 Huang in view of Yoo in order to further modify transmitting a sounding reference signal (SRS) using a resource that comprises a specified number of symbols, wherein each symbol of the specified number of symbols comprises a single unit of a time resource and the SRS occupying every Nth subcarrier in one or more resource blocks (RBs) of each symbol of the at least two symbols, wherein N is selected from a set comprising 2, 4, and 8, and transmitting the SRS using RB level frequency hopping across different symbols using one or more different respective RBs in the at least two symbols across the plurality of symbols from the teachings of Yoo.
One of ordinary skill in the art would have been motivated because it is possible to achieve SRS capacity enhancement independent of coexistence with legacy UEs (Yoo: [0061]).
Yet, Huang in view of Yoo does not explicitly disclose:
wherein transmitting the SRS further comprises hopping of comb offsets, where N is a comb size, and wherein transmitting the SRS over different respective subcarriers in at least two symbols across the specified number of symbols comprises using different comb offsets for different symbols of the at least two symbols.
However, in the same field of endeavor, Cha teaches:
wherein transmitting the SRS further comprises hopping of comb offsets, where N is a comb size, and wherein transmitting the SRS over different respective subcarriers in at least two symbols across the specified number of symbols comprises using different comb offsets for different symbols of the at least two symbols (In an SRS resource, different SRS symbols having a Comb-N form may have different comb-offsets, that is, frequency RE offsets. Referring to FIG. 18, in each symbol, REs may be mapped at intervals of comb size N (N=4) from the RE separated by the comb-offset value (3, 0, 1, 2) for each symbol from the RE that is positioned first in the frequency domain. BS/location server may set/indicate, to the UE, the comb size N, comb-offset, and relative combo-offset for each SRS resource, Cha: Fig. 18, Fig. 21, [0280]-[0282], [0299], [0314]-[0316]):
Therefore, 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 Huang and Yoo in view of Cha in order to further modify transmitting the SRS further comprises hopping of comb offsets, where N is a comb size, and wherein transmitting the SRS over different respective subcarriers in at least two symbols across the specified number of symbols comprises using different comb offsets for different symbols of the at least two symbols from the teachings of Cha.
One of ordinary skill in the art would have been motivated because various examples may be considered to reduction signaling overhead for backward compatibility and SRS resource configuration (Cha: [0282]).
Regarding claim 2, Huang-Yoo-Cha teaches all the claimed limitations as set forth in the rejection of claim 1 above.
Huang further discloses:
wherein when transmitting the SRS comprises (b), a different precoder is applied to each different symbol of the specified number of symbols (UE may further listen for additional signaling from the eNB identifying other precoding that the UE should use for transmitting data in the PUSCH. eNB may configure the UE to sound multiple SRS (e.g., over different symbols as an example), each SRS with a different precoder. eNB may measure the differently precoded SRS over different symbols. the UE may set the precoder for the SRS to be the same as the whitening matrix (e.g., the interference plus noise measured at the UE) for the UE, Huang: [0028]-[0029], [0042] - [0046]).
Regarding claim 3, Huang-Yoo-Cha teaches all the claimed limitations as set forth in the rejection of claim 2 above.
Huang further discloses:
wherein whether a different precoder is to be applied to each different symbol is either predetermined or is configured by higher layer signaling (eNB may measure the differently precoded SRS over different symbols and select the best precoder (i.e., the precoded SRS with the best measured characteristic from among the precoded SRSs measured). With the precoder selected, the eNB may signal the UE to use that selected precoder for UL PUSCH transmission. the eNB 104 may apply singular vector decomponsition (SYD) or another approach, based on the determined properties of the raw channel, to determine the best precoder for DL PDSCH transmission, Huang: [0042]-[0046]).
Regarding claim 4, Huang-Yoo-Cha teaches all the claimed limitations as set forth in the rejection of claim 1 above.
Huang further discloses:
wherein physical resource blocks for a physical uplink data channel in a non-codebook based transmission corresponding to an SRS symbol are considered as a physical resource block group (The precoded SRS may be used for DL PDSCH scheduling. This relates to whether the eNB 104 has knowledge of the UE 102's measured covariance matrix of interference plus noise. A resource grid may be used to represent two time slots, each time slot including a resource block (RB). multiple RBs (e.g., representing multiple groupings of subcarriers) may be grouped together as the resource block groups, Huang: [0045]-[0046], [0072]-[0073]).
Regarding claim 7, Huang-Yoo-Cha teaches all the claimed limitations as set forth in the rejection of claim 1 above.
Huang does not explicitly disclose:
wherein a slot offset for transmitting the SRS is changeable by downlink control information.
However, in the same field of endeavor, Yoo teaches:
wherein a slot offset for transmitting the SRS is changeable by downlink control information (The frequency hopping pattern may be notified to the UE dedicatedly via an RRC message or DCI. The parameters necessary for transmitting the SRS may be transmitted to the UE in an RRC message or DCI format. 'srs-Configindex-Ap-rlO' denotes an SRS transm1ss10n subframe index for acquiring the trigger type 1 period and offset information; srs-ConfigApDCI-Format4-r10, srs-ConfigApDCI-FormatO-rlO, and srs-ConfigApDCIFormatlalb2c-310 are SRS configuration information to be used for the respective DCI formats triggering the transmission, Yoo: [0073]-[0080], [0135], [0169]).
Therefore, 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 Huang and Cha in view of Yoo in order to further modify that a slot offset for transmitting the SRS is changeable by downlink control information from the teachings of Yoo.
One of ordinary skill in the art would have been motivated because it is possible to achieve SRS capacity enhancement independent of coexistence with legacy UEs (Yoo: [0061]).
Regarding claim 11, Huang discloses:

A resource grid may be used to represent two time slots, each time slot including a resource block (RB). resource block may contain 12 consecutive subcarriers in the frequency domain, Huang: Fig.5A~5C, [0072]-[0080]).
Huang does not explicitly disclose:

(b) determining a first slot offset for the SRS transmission based on a field in downlink control information (DCI) usable to adjust a second slot offset for the SRS previously configured by radio resource control (RRC) signaling,
However, in the same field of endeavor, Yoo teaches:

(b) determining a first slot offset for the SRS transmission based on a field in downlink control information (DCI) usable to adjust a second slot offset for the SRS previously configured by radio resource control (RRC) signaling (the SRS periodicity and offset value corresponding to the SRS configuration index (ISRS) may be determined according to the table of FIG. 10. the srs-SubframeConfig is a cell-specific parameter transmitted to the VE using the SIB or RRC message. The frequency hopping pattern may be notified to the UE dedicatedly via an RRC message or DCI. The parameters necessary for transmitting the SRS may be transmitted to the UE in an RRC message or DCI format. 'srs-Configindex-Ap-rlO' denotes an SRS transmission subframe index for acquiring the trigger type 1 period and offset information; srs-ConfigApDCI-Format4-r10, srs-ConfigApDCI-FormatO-rlO, and srs-ConfigApDCIFormatlalb2c-310 are SRS configuration information to be used for the respective DCI formats triggering the transmission. if the extended RRC message is received, the UE transmits SRS in the extended area and there is a need to use srs-ConfigindexAp-rl0 in a different way. In this case, it is necessary to adjust the SRS periodicity and subframe offset to match with the subframe index to transmit the trigger type 1 SRS transmission, Yoo: Fig. 10, [0073]-[0080], [0090]-[0095], [0101], [0135], [0169], [0180]),
Therefore, 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 Huang in view of Yoo in order to further modify transmitting a sounding reference signal (SRS) using a resource that comprises a specified number of symbols, wherein each symbol of the specified number of symbols comprises a single unit of a time resource and the SRS occupying every Nth subcarrier in one or more resource blocks (RBs) of each symbol of the at least two symbols, wherein N is selected from a set comprising 2, 4, and 8, and determining a first slot offset for the SRS transmission based on a field in downlink control information (DCI) usable to adjust a second slot offset for the SRS previously configured by radio resource control (RRC) signaling from the teachings of Yoo.
One of ordinary skill in the art would have been motivated because it is possible to achieve SRS capacity enhancement independent of coexistence with legacy UEs (Yoo: [0061]).

wherein for each of the at least two symbols the SRS occupies at least two subcarriers, wherein the SRS occupies every Nth subcarrier in one or more resource blocks (RBs) of each symbol of the at least two symbols, wherein N is selected from a set comprising 2, 4, and 8 (Referring to FIG. 7, both the UE1 and UE2 transmit the SRS over the entire band across two symbols so as to achieve a gain of 3 dB as in the method of FIG. 6. Here, the two UEs use different time-orthogonal codes so as to perform estimation without interference with each other. the parameters added to the legacy configuration information include Number-of-combs indicating the number of combs (subcarrier pattern type for SRS transmission). transmissionComb-rl3 indicating comb type (subcarrier pattern for SRS transmission), and cyclicShiftr13 for supporting the cyclic shift up to 12. For example, Number-of-combs may indicate 2 combs supported in the legacy system or 4 combs supported newly, Yoo: Fig.6~7, Fig.14, [0022], [0073]-[0080], [0143]); and

The parameters necessary for transmitting the SRS may be transmitted to the UE in an RRC message or DCI format. 'srs-Configindex-Ap-rlO' denotes an SRS transmission subframe index for acquiring the trigger type 1 period and offset information; srs-ConfigApDCI-Format4-r10, srs-ConfigApDCI-FormatO-rlO, and srs-ConfigApDCIFormatlalb2c-310 are SRS configuration information to be used for the respective DCI formats triggering the transmission, Yoo: [0073]-[0080], [0135], [0169]),
Therefore, 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 Huang in view of Yoo in order to further modify receiving a sounding reference signal (SRS) using a resource that comprises a specified number of symbols and each of the at least two symbols the SRS occupying at least two subcarriers and receiving the SRS using RB level frequency hopping across different symbols using one or more different respective RBs in the at least two symbols across the plurality of symbols from the teachings of Yoo.

when receiving the SRS comprises (b), a different precoder is applied to each different symbol of the specified number of symbols (UE may further listen for additional signaling from the eNB identifying other precoding that the UE should use for transmitting data in the PUSCH. UE has multiple transmit port and configure to sound multiple SRS (e.g., over different symbols), each SRS with a different precoder. eNB may measure the differently precoded SRS over different symbols, Huang: [0028]-[0029], [0042]-[0046]).
