Information Disclosure Statement
The information disclosure statements (IDS) submitted on 9/18/2024 are in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statements are being considered by the examiner.
Specification
The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed.
Drawings
The drawings are objected to because in Fig. 2, the directions of “Transmit information” (2010) and “Transmit capability information” (2020) should be reversed per paragraph [0037] and [00248] of the specification.
Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance.
Claim Objections
Claim 49 is objected to because of the following informalities:
In claim 49, lines 1-2, “comprising a processor configured to cause the terminal device to:” should read “comprising: a processor configured to cause the terminal device to:”.

For the x-port port selection, a value of the first port is 1, and a value (in other words, phase) of another port can take {1, j, −1, −j} (here, j is an imaginary number). Considering these, M=C(8, x)*4.sup.(x-1) candidates are present for candidates M for the 8-port 1-layer PC precoder.
