DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
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 (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 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 1-10 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Abotabl et al. (2022/0416867) [Abotabl].
Regarding claims 1 and 6, Abotabl discloses a channel information obtaining method, comprising:
obtaining a frequency division duplex (FDD) downlink channel and a time division duplex (TDD) channel (paragraphs 0053-0054 and 0061);
determining a first channel based on the FDD downlink channel and the TDD channel (at least one channel will have a reference signal with channel state information, paragraph 0064);
performing inverse discrete Fourier transform (IDFT) on the first channel to obtain a second channel (paragraph 0069); and
sending first information based on the second channel (reference signal transmitted from user equipment, paragraph 0066).
Regarding claims 2 and 7, Abotabl discloses the method and apparatus according to claims 1 and 6, wherein sending the first information based on the second channel comprises:
obtaining first energy of the second channel based on the second channel wherein the first energy is a sum of energy of all coefficients in the second channel (paragraphs 0011 and 0056);
determining second energy based on the first energy, wherein the second energy is a sum of energy coefficient in a set A; and determining the first information based on the second energy, wherein the first information comprises position information and phase information of the set A on the second channel (determining the channel based on measurements send form user equipment, paragraph 0066).
Regarding claims 3 and 8, Abotabl discloses the method and apparatus according to claims 1 and 7, wherein obtaining the FDD downlink channel and the TDD channel comprises:
receiving a first reference signal, wherein the first reference signal is from a network device; and obtaining the FDD downlink channel and the TDD channel based on the first reference signal (paragraph 0064).
Regarding claims 4 and 9, Abotabl discloses the method and apparatus according to claims 1 and 6, wherein the determining a first channel based on the FDD downlink channel and the TDD comprises:
performing a first operation on the FDD downlink channel and the TDD channel based on first indication information to obtain the first channel wherein the first indication information comprises a start point and an end point of a bandwidth of the first channel (physical layer, paragraph 0065).
Regarding claims 5 and 10, Abotabl discloses the method and apparatus according to claims 4 and 9, wherein the first operation comprises concatenation (paragraph 0068-0072).
Allowable Subject Matter
Claims 11-17 are allowed. The claimed invention is directed towards a channel information obtaining apparatus the receives an FDD uplink channel and TDD channel and performs FDD downlink channel discovery based on the received uplink channel. Essentially the inverse of what is conventionally done in the prior art (as shown above, where a client receiver is in communication with a base station, receives downlink channels and returns measurements to said base station in the form of a reference signal for establishing communication). The examiner found no teaching or reasonably suggestion to determine FDD downlink channels in the manner claimed in the prior art at the time of effective filing.
