Claim Interpretation
The following is a quotation of 35 U.S.C. 112(f):
(f) Element in Claim for a Combination. – An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.
The limitation “the signal message is configured to…”, as noted in claim 1 and similarly in claims 6, 11 and 16, is considered as a well-known structural element, therefore, 35 U.S.C. 112(f) is NOT invoked.
Claim Objections
Claim 5 is objected to because of the following informalities: claim 5, line 1 notes, “PTRS” which is an anachronym which is not defined. For the purpose of furthering prosecution, the limitation “PTRS” is considered as associated with “Phase Tracking Reference Signal” as well-known in the art. Appropriate correction is required.
Claim 10 is objected to because of the following informalities: claim 10, line 1 notes, “PTRS” which is an anachronym which is not defined. For the purpose of furthering prosecution, the limitation “PTRS” is considered as associated with “Phase Tracking Reference Signal” as well-known in the art. Appropriate correction is required.
Claim 15 is objected to because of the following informalities: claim 15, line 1 notes, “PTRS” which is an anachronym which is not defined. For the purpose of furthering prosecution, the limitation “PTRS” is considered as associated with “Phase Tracking Reference Signal” as well-known in the art. Appropriate correction is required.
Claim 20 is objected to because of the following informalities: claim 20, line 1 notes, “PTRS” which is an anachronym which is not defined. For the purpose of furthering prosecution, the limitation “PTRS” is considered as associated with “Phase Tracking Reference Signal” as well-known in the art. Appropriate correction is required.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
Claims(s) 3, 8, 13 and 18 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 3 recites the limitation "ceil" in line 3. It is unclear what “ceil” is referring to, therefore the claim is indefinite. For the purposes of furthering prosecution, the limitation is ignored.
Claim 8 recites the limitation "ceil" in line 3. It is unclear what “ceil” is referring to, therefore the claim is indefinite. For the purposes of furthering prosecution, the limitation is ignored.
Claim 13 recites the limitation "ceil" in line 3. It is unclear what “ceil” is referring to, therefore the claim is indefinite. For the purposes of furthering prosecution, the limitation is ignored.
Claim 18 recites the limitation "ceil" in line 3. It is unclear what “ceil” is referring to, therefore the claim is indefinite. For the purposes of furthering prosecution, the limitation is ignored.
Claim Rejections - 35 USC § 102
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 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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:

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 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.
Claim(s) 2, 7, 12 and 17 is/are rejected under 35 U.S.C. 103 as being unpatentable over Dou et al. US 20200374017 in view of Gao et al. US 20220311574.
As to claim 2:
Dou et al. as described above does not explicitly teach:

However, Guo et al. further teaches a co-scheduled capability which includes:
wherein the at least two groups of antenna ports are organized based on a predefined or configured set of DMRS ports, wherein the at least two groups of antenna ports are associated with the communication with the target terminal device, and wherein at least one other group of antenna ports from the set of DMRS ports is associated with another communication with another co-scheduled terminal device.

wherein at least two PTRS-DMRS association fields are associated with the at least two DMRS port groups, and each of the at least two PTRS-DMRS association fields is associated with one of the at least two DMRS port groups.
(“In summary, the method for determining an association of an uplink PTRS port provided in the present embodiment defines two information fields on the DCI, and 2 bits on each information field are configured to indicate the association between one uplink PTRS port and one uplink DMRS port in one DMRS port group, where the two DMRS port groups are obtained by dividing up the at most 8 uplink DMRS ports, and the two DMRS port groups are in a one-to-one correspondence with the two uplink PTRS ports. The method is used for supporting estimation of a common phase error in uplink transmission when the terminal uses the at most 8 sending antenna ports, for example, for supporting the terminal to use the 8 sending antenna ports to detect a common phase error in a scenario of CB-based uplink transmission, or, for supporting the terminal to use the 8 v antenna ports to detect a common phase error in a scenario of NCB-based uplink transmission.”; Gao; 0111)
Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to implement the fields capability of Gao into Dou et al. By modifying the processing/communications of Dou et al. to include the fields capability as taught by the processing/communications of Gao, the benefits of improved scalability (Dou et al.; 0099) with improved association (Gao; Abstract) are achieved.
