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 § 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 7-12 are rejected under 35 U.S.C. 103 as being unpatentable over Wang et al (US 2020/0382180) in view of Ren et al (US 2020/0036425). a) Regarding claims 7 and 10, Wang et al disclose a terminal (501 in Fig. 5) comprising:
a processor that (Fig. 6; Pub [0087]), when a codebook is configured, determines a precoder based on the codebook, the codebook being a non-coherent codebook or a partial-coherent codebook for transmission using antenna ports (Fig. 4C and 4D; Pub [0033], [0062]); and
a transmitter that performs uplink (UL) full power transmission based on the precoder (608 in Fig. 6; Pub [0104], [0062]).
Wang et al disclose codebook selection transmission precoding matrix indexed (TPMIs) to enable full power uplink transmissions according to four antenna ports. Wang et al did not explicitly teach using more than four antenna ports.
However, Ren et al disclose information transmission method including transmit TPMI corresponding to a codebook of eight antenna ports (Pub [0139]). TPMI is commonly and widely used for uplink data measurement for predefined codebook selection to optimize channel use in a communication system. To increase the number of antenna port would allow higher data capacity. Therefore, it is obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to adapt the TPMI corresponding to a codebook of eight antenna ports of Ren et al with the full power uplink transmission system of Wang et al to support more than four antenna ports. By doing so, increase data capacity, optimize signal quality and throughput in a precoding process of a wireless communication system. b) Regarding claim 11, Wang et al disclose a base station comprising (510 in Fig. 5; Pub [0075]):
a transmitter that transmits, to a terminal (501), information for configuring a codebook that is a non-coherent codebook or a partial-coherent codebook for transmission using four antenna ports (Fig. 4C and 4D; Pub [0030], [0033], [0062]; UE configuring precoder in accordance of the BS); and
a receiver that receives uplink (UL) full power transmission that is transmitted based on a precoder determined based on the codebook (Pub [0062]; UE to transmit, BS inherently to receive).
Wang et al disclose codebook selection transmission precoding matrix indexed (TPMIs) to enable full power uplink transmissions according to four antenna ports. Wang et al did not explicitly teach using more than four antenna ports.
However, Ren et al disclose information transmission method including transmit TPMI corresponding to a codebook of eight antenna ports (Pub [0139]). TPMI is commonly and widely used for uplink data measurement for predefined codebook selection to optimize channel use in a communication system. To increase the number of antenna port would allow higher data capacity. Therefore, it is obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to adapt the TPMI corresponding to a codebook of eight antenna ports of Ren et al with the full power uplink transmission system of Wang et al to support more than four antenna ports. By doing so, increase data capacity, optimize signal quality and throughput in a precoding process of a wireless communication system. c) Regarding claim 12, Wang et al disclose a system comprising a terminal (501 in Fig. 5) and a base station (510), wherein:
the terminal comprises: a processor that (Fig. 6; Pub [0087]), when a codebook is configured, determines a precoder based on the codebook, the codebook being a non-coherent codebook or a partial-coherent codebook for transmission using four antenna ports (Fig. 4C and 4D; Pub [0033], [0062]); and a transmitter that performs uplink (UL) full power transmission based on the precoder (608 in Fig. 6; Pub [0104], [0062]), and
the base station comprises: a receiver that receives the UL full power transmission (Pub [0062]; UE to transmit, BS inherently to receive).
Wang et al disclose codebook selection transmission precoding matrix indexed (TPMIs) to enable full power uplink transmissions according to four antenna ports. Wang et al did not explicitly teach using more than four antenna ports.

Therefore, it is obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to adapt the TPMI corresponding to a codebook of eight antenna ports of Ren et al with the full power uplink transmission system of Wang et al to support more than four antenna ports. By doing so, increase data capacity, optimize signal quality and throughput in a precoding process of a wireless communication system. d) Regarding claim 8, Wang et al disclose wherein when full power transmission mode 1 is configured, the precoder is a full-coherent precoder (Pub [0033]).
e) Regarding claim 9, Wang et al disclose wherein the transmitter transmits capability information indicating support of full power transmission mode 1 using more than four antenna ports (Pub [0037-0038], [0047-0048]).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. US 2022/0039031 Rahman et al disclose capability signaling to enable full power uplink transmission. US 11,502,732 Bengtsson et al disclose channel estimation and precoders.
