Specification
The lengthy specification has not been checked to the extent necessary to determine the presence of all possible minor errors. Applicant’s cooperation is requested in correcting any errors of which applicant may become aware in the specification.
Claim Objections
Claims 2-20 are objected to because of the following informalities:
Claim 2 (line 17), claim 7 (lines 17-18), and claim 17 (line 18), the phrase “the two elements” should be “the QPSK two elements”.
Claims 3, 8, 12, and 18, “3O” should be “30”.
6. (Proposed Amendment) A terminal device comprising:
a memory configured to store a computer program; and
a processor configured to execute the computer program stored in the memory[[, and]] to implement a wireless communication unit to:
receive a transmit precoding matrix indicator (TPMI) and a transmitted rank indicator (TRI) transmitted by a network device;
determine, based on the TPMI, a precoding matrix from a codebook corresponding to the TRI, wherein each codeword of the codebook comprises 3 rows;
perform a precoding process of data with the precoding matrix; and
transmit data that has been precoded.
16. (Proposed Amendment) A network device comprising:
a memory configured to store a computer program; and
a processor configured to execute the computer program stored in the memory[[, and]] to implement a wireless communication unit to:
determine a precoding matrix from a codebook corresponding to a transmitted rank indicator (TRI), wherein, each codeword in the codebook comprises 3 rows; and
transmit the TRI and a transmit precoding matrix indicator (TPMI) corresponding to the precoding matrix to a terminal device, wherein, the TPMI is configured to be used by the terminal device to determine the precoding matrix from the codebook corresponding to the TRI.
Claims 4 and 5 depend from claim 2, therefore they are also objected.
Claims 9-11 and 13-15 depend from claim 7, therefore they are also objected.
Claims 19 and 20 depend from claim 17, therefore they are also objected.
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.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 2-5, 7-15, and 17-20 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 2 (lines 2, 8, and 19), claim 3 (line 3), claim 7 (lines 2, 8, and 19), claim 8 (line 3), claim 12 (line 3), claim 17 (lines 2, 8, and 19), and claim 18 (line 3), the phrases “the number of the transport layers” and “the DFT vector” lack antecedent basis.
Claims 3, 8, and 18, the letter “T” recited in the equation of the claims is undefined.
Claims 4 and 5 depend from claim 2, therefore they are also rejected.
Claims 9-11 and 13-15 depend from claim 7, therefore they are also rejected.
Claims 19 and 20 depend from claim 17, therefore they are also rejected.
Allowable Subject Matter
Claim 1 is allowed.
Claims 2-20 would be allowable if rewritten or amended to overcome the objection(s) set forth in this Office action.
Claims 2-5, 7-15, and 17-20 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
GAO et al. (US 2016/0056870 A1) relates to a method comprising: determining, by a user equipment, a third pre-coding matrix according to a first pre-coding matrix and a second pre-coding matrix; determining, by the user equipment, an overall pre-coding matrix according to the determined third pre-coding matrix, wherein the overall pre-coding matrix is a sub-matrix of the third pre-coding matrix; and determining, by the user equipment, overall pre-coding matrix information according to the overall pre-coding matrix, and transmitting the overall pre-coding matrix information to a network-side device.
Onggosanusi et al. (US 2016/0329945 A1) relates to a transceiver configured to receive configuration information for a channel state information (CSI) reporting and receive configuration information for a plurality of precoding codebook parameters. The processor is operably connected to the transceiver, and configured to calculate, in response to receipt of the configuration information for the CSI reporting and the configuration information for the plurality of precoding codebook parameters, a first precoding matrix indicator (PMI) and a second PMI, wherein the first PMI includes one or two codebook indices. The transceiver further configured to transmit the CSI reporting on an uplink channel, the CSI reporting including a channel quality indicator (CQI), a rank indicator (RI), and the calculated first and second PMIs.
Huang et al. (US 2020/0119788 A1) relates to a method comprising: receiving, by a first device, a reference signal used for channel measurement; and sending, by the first device, at least one precoding matrix indicator PMI and a rank indication RI based on the reference signal, where the PMI is used to indicate a precoding matrix in a codebook corresponding to the RI, the precoding matrix in the codebook includes a plurality of matrices in a one-to-one correspondence with a plurality of antenna port groups, a matrix corresponding to one antenna port group or each of at least two antenna port groups has two different inter-antenna-port-group phase factors, and any two column vectors in the precoding matrix are orthogonal to each other.
RAMIREDDY et al. (US 2021/0167825 A1) relates to a receiver processes a radio signal received via a radio channel from a transmitter employing a plurality of antenna ports, determines complex precoder coefficients and delays of one or more space-delay precoders for one or more transmission layers and antenna ports at the transmitter so as to achieve a predefined property for a communication over the radio channel, and feeds back, explicitly or implicitly, delays and the complex precoder. The space-delay precoder has a dual-stage structure having a spatial codebook matrix including spatial beamforming vectors, a frequency-domain codebook matrix, and a combining element per layer for complex scaling or combining one or more of the vectors selected from the spatial and/or frequency-domain codebook matrices. The frequency-domain codebook matrix is defined by a sub-matrix of a DFT matrix, which the sub-matrix of the DFT matrix is associated with a range of delay values.
RAMIREDDY et al. (US 2021/0226674 A1) relates to a communication device providing CSI feedback in a wireless communication system includes a transceiver to receive downlink reference signals and downlink signals including a reference signal configuration. A processor estimates an explicit CSI in the frequency domain. The processor selects a Doppler-delay-beam precoder matrix for a composite Doppler-delay-beam three-stage precoder, which is based on one or more codebooks including one or more transmit-side spatial beam components, one or more delay components, and one or more Doppler-frequency components. The processor calculates a CQI and/or a PMI and/or a rank indicator, RI, using the explicit CSI and the composite Doppler-delay-beam three-stage precoder, and reports the CSI feedback including the CQI, and/or the PMI and/or the RI. The one or more delay and/or Doppler-frequency components are defined by one or more sub-matrices of a DFT matrix or an oversampled DFT matrix.
