The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 14-15 and 40-41 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Xiao et al. (U.S. PGPub 2024/0333460), hereinafter referred to as Xiao.
Regarding claim 14, Xiao discloses a resource indication method, comprising:
determining downlink control information (DCI) (implied by the fact that the base station transmits the DCI with the SRI fields; See [0072], [0075] and [0144]), wherein the DCI comprises multiple sounding reference signal (SRS) resource indicator (SRI) fields (DCI comprises first and second SRI fields; See [0075]), a bit width of a first SRI field in the multiple SRI fields is determined based on the number of resources comprised in at least one SRS resource set among multiple SRS resource sets (The BS also needs to determine the first bit width and the second bit width. That is, after transmitting the configuration information, in step 203, the BS may determine the first bit width of the first SRI field and the second bit width of the second SRI field in the DCI. The BS may also determine that the first bit width of the SRI field in the DCI associated with the one SRS resource set (which includes more than one SRS resource) is no less than 1 bit, and the second bit width of the SRI field in the DCI associated with the other SRS resource set (which includes only one SRS resource) is 0 bit; See [0075] and [0144]); and

The BS also needs to determine the first bit width and the second bit width. That is, after transmitting the configuration information, in step 203, the BS may determine the first bit width of the first SRI field and the second bit width of the second SRI field in the DCI. The BS may also determine that the first bit width of the SRI field in the DCI associated with the one SRS resource set (which includes more than one SRS resource) is no less than 1 bit, and the second bit width of the SRI field in the DCI associated with the other SRS resource set (which includes only one SRS resource) is 0 bit.

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 (i.e., changing from AIA to pre-AIA ) 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.
Claims 1-5, 9-11, 16-18, 22-24 and 27-28 are rejected under 35 U.S.C. 103 as being unpatentable over Xiao in view of Park et al. (U.S. PGPub 2019/0207731), hereinafter referred to as Park.
Regarding claim 1, Xiao teaches a resource indication method, comprising:
receiving downlink control information (DCI) (the UE may receive the configuration information of the first SRS resource set and the second SRS resource set from the BS; See [0073]), the DCI comprising multiple sounding reference signal (SRS) resource indicator (SRI) fields (first and second SRI fields; See [0074]); and
determining a bit width of a first SRI field in the multiple SRI fields based on the number of resources comprised in at least one SRS resource set among multiple SRS resource sets (the UE may determine a first bit width of a first SRI field and a second bit width of a second SRI field in DCI; See [0074]).
While Xiao teaches of having SRS resources and resource sets (See [0072]), it fails to explicitly teach of determining an SRS resource corresponding to an uplink transmission based on the bit width of the first SRI field.
Park teaches determining an SRS resource corresponding to an uplink transmission based on the bit width of the first SRI field (the UE transmits an uplink to the base station by applying precoding indicated by the precoding indication on an antenna port of an SRS transmitted in an SRS resource selected by the SRI, suggesting that the resource is determined before the transmitting occurs; See [0450]).
Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the method of Xiao to include determining an SRS resource corresponding to an uplink transmission based on the bit width of the first SRI field taught by Park in order to enhance uplink transmission throughput.
Regarding claim 2, Xiao further teaches the resource indication method of claim 1, wherein determining the bit width of the first SRI field in the multiple SRI fields based on the number of resources comprised in at least one SRS resource set among multiple SRS resource sets comprises:
determining the bit width of the first SRI field based on the number of resources comprised in an SRS resource set corresponding to the first SRI field among the multiple SRS resource sets (the UE may determine that a first bit width of an SRI field in DCI associated with the one SRS resource set (which includes more than one SRS resource) is no less than 1 bit, and a second bit width of an SRI field in the DCI associated with the other SRS resource set (which includes only one SRS resource) is 0 bit. It is assumed that two SRS resource sets are configured for a UE for CB based PUSCH transmission, and the first SRS resource set contains two SRS resources and the second SRS resource set contains one SRS resource. In the case that the first SRI field is associated with the first SRS resource set and has a bit width determined based on N.sub.m,SRS, and the second SRI field is associated with the second SRS resource set and has a bit width determined based on N.sub.2,SRS, the first SRI field is 1 bit and the second SRI field is 0 bit; See [0144] and [0151]).
Regarding claim 3, Xiao fails to teach the resource indication method of claim 2, wherein the number of resources comprised in the SRS resource set corresponding to the first SRI field is equal to or greater than the number of resources comprised in each of SRS resource sets other than the SRS resource set corresponding to the first SRI field among the multiple SRS resource sets.
Park teaches wherein the number of resources comprised in the SRS resource set corresponding to the first SRI field is equal to or greater than the number of resources comprised in each of SRS resource sets other than the SRS resource set corresponding to the first SRI field among the multiple SRS resource sets (In the case of the codebook-based UL, multiple SRS resource sets may be configured in the UE. Only one SRS resource may be configured in each SRS resource set; See [0634]-[0635]).
Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the method of Xiao to include wherein the number of resources comprised in the SRS resource set corresponding to the first SRI field is equal to or greater than the number of resources comprised in each of SRS resource sets other than the SRS resource set corresponding to the first SRI field among the multiple SRS resource sets taught by Park in order to enhance uplink transmission throughput.

That is, N.sub.m,SRS=max(N.sub.1,SRS, N.sub.2,SRS), wherein N.sub.1,SRS is the number of SRS resource(s) in the first SRS resource set and N.sub.2,SRS is the number of SRS resource(s) in the second SRS resource set; See [0096]); or
wherein determining the bit width of the first SRI field based on the maximum value among numbers of resources comprised in each of the multiple SRS resource sets comprises: determining the bit width of the first SRI field based on the maximum value among the numbers of resources comprised in each of the multiple SRS resource sets and at least one of a minimum value among numbers of resources comprised in each of the multiple SRS resource sets and a maximum number of transmission layers.
Regarding claim 5, Xiao fails to teach the resource indication method of claim 2, wherein among the multiple SRI fields comprised in the DCI, a second SRI field indicates the number of transmission layers and SRS resources corresponding to the second SRI field, and SRI fields other than the second SRI field among the multiple SRI fields indicate SRS resources corresponding to the number of transmission layers; and the number of resources comprised in the SRS resource set corresponding to the second SRI field is equal to or greater than the number of resources comprised in each of SRS resource sets other than the SRS resource set corresponding to the second SRI field among the multiple SRS resource sets.
Park teaches wherein among the multiple SRI fields comprised in the DCI, a second SRI field indicates the number of transmission layers and SRS resources corresponding to the second SRI field, and SRI fields other than the second SRI field among the multiple SRI fields indicate SRS resources corresponding to the number of transmission layers (a bit width of an SRI field carrying the SRI may be determined based on a number of SRS resources in an SRS resource set configured to the UE and a maximum number of layers supported for uplink transmission; See [0019]); and the number of resources comprised in the SRS resource set corresponding to the second SRI field is equal to or greater than the number of resources comprised in each of SRS resource sets other than the SRS resource set corresponding to the second SRI field among the multiple SRS resource sets (In the case of the codebook-based UL, multiple SRS resource sets may be configured in the UE. Only one SRS resource may be configured in each SRS resource set; See [0634]-[0635]).
Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the method of Xiao to include wherein among the multiple SRI fields comprised in the DCI, a second SRI field indicates the number of transmission layers and SRS resources corresponding to the second SRI field, and SRI fields other than the second SRI field among the multiple SRI fields indicate SRS resources corresponding to the number of transmission layers; and the number of resources comprised in the SRS resource set corresponding to the second SRI field is equal to or greater than the number of resources comprised in each of SRS resource sets other than the SRS resource set corresponding to the second SRI field among the multiple SRS resource sets taught by Park in order to enhance uplink transmission throughput.
Regarding claim 9, Xiao fails to teach the resource indication method of claim 1, wherein determining the bit width of the first SRI field in the multiple SRI fields based on the number of resources comprised in at least one SRS resource set among multiple SRS resource sets comprises: in case that numbers of resources comprised in the multiple SRS resource sets are the same, determining the bit width of the first SRI field in the multiple SRI fields based on the number of resources comprised in one SRS resource set among the multiple SRS resource sets and a maximum number of transmission layers.
Park teaches wherein determining the bit width of the first SRI field in the multiple SRI fields based on the number of resources comprised in at least one SRS resource set among multiple SRS resource sets comprises: in case that numbers of resources comprised in the multiple SRS resource sets are the same (Only one SRS resource may be configured in each SRS resource set; See [0635]), determining the bit width of the first SRI field in the multiple SRI fields based on the number of resources comprised in one SRS resource set among the multiple SRS resource sets and a maximum number of transmission layers (a bit width of an SRI field carrying the SRI may be determined based on a number of SRS resources in an SRS resource set configured to the UE and a maximum number of layers supported for uplink transmission; See [0019]).
Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the method of Xiao to include wherein determining the bit width of the first SRI field in the multiple SRI fields based on the number of resources comprised in at least one SRS resource set among multiple SRS resource sets comprises: in case that numbers of resources comprised in the multiple SRS resource sets are the same, determining the bit width of the first SRI field in the multiple SRI fields based on the number of resources comprised in one SRS resource set among the multiple SRS resource sets and a maximum number of transmission layers taught by Park in order to enhance uplink transmission throughput.
Regarding claim 10, Xiao further teaches the resource indication method of claim 1, wherein a bit width of a third SRI field other than the first SRI field among the multiple SRI fields is determined based on at least one of the number of resources comprised in an SRS resource set corresponding to the third SRI field (the UE may determine that a first bit width of an SRI field in DCI associated with the one SRS resource set (which includes more than one SRS resource) is no less than 1 bit, and a second bit width of an SRI field in the DCI associated with the other SRS resource set (which includes only one SRS resource) is 0 bit.

Only one SRS resource may be configured in each SRS resource set; See [0634]-[0635]).
Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the method of Xiao to include wherein the number of resources comprised in the SRS resource set corresponding to the first SRI field is equal to or greater than the number of resources comprised in each of SRS resource sets other than the SRS resource set corresponding to the first SRI field among the multiple SRS resource sets taught by Park in order to enhance uplink transmission throughput.

That is, N.sub.m,SRS=max(N.sub.1,SRS, N.sub.2,SRS), wherein N.sub.1,SRS is the number of SRS resource(s) in the first SRS resource set and N.sub.2,SRS is the number of SRS resource(s) in the second SRS resource set; See [0096]); or

Regarding claim 23, Xiao further teaches the resource indication method of claim 14, wherein a bit width of a third SRI field other than the first SRI field among the multiple SRI fields is determined based on at least one of the number of resources comprised in an SRS resource set corresponding to the third SRI field (the UE may determine that a first bit width of an SRI field in DCI associated with the one SRS resource set (which includes more than one SRS resource) is no less than 1 bit, and a second bit width of an SRI field in the DCI associated with the other SRS resource set (which includes only one SRS resource) is 0 bit. It is assumed that two SRS resource sets are configured for a UE for CB based PUSCH transmission, and the first SRS resource set contains two SRS resources and the second SRS resource set contains one SRS resource.

While Xiao teaches of having SRS resources and resource sets (See [0072]), it fails to explicitly teach of determining an SRS resource corresponding to an uplink transmission based on the bit width of the first SRI field.
Park teaches determining an SRS resource corresponding to an uplink transmission based on the bit width of the first SRI field (the UE transmits an uplink to the base station by applying precoding indicated by the precoding indication on an antenna port of an SRS transmitted in an SRS resource selected by the SRI, suggesting that the resource is determined before the transmitting occurs; See [0450]).
Therefore it would have been obvious to one of ordinary skill in the art at the time before the effective filing date of the invention, to modify the apparatus of Xiao to include determining an SRS resource corresponding to an uplink transmission based on the bit width of the first SRI field taught by Park in order to enhance uplink transmission throughput.

It is assumed that two SRS resource sets are configured for a UE for CB based PUSCH transmission, and the first SRS resource set contains two SRS resources and the second SRS resource set contains one SRS resource. In the case that the first SRI field is associated with the first SRS resource set and has a bit width determined based on N.sub.m,SRS, and the second SRI field is associated with the second SRS resource set and has a bit width determined based on N.sub.2,SRS, the first SRI field is 1 bit and the second SRI field is 0 bit; See [0144] and [0151]).
