Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on February 13, 2026 has been entered.
Response to Arguments
Applicant’s arguments, see Applicants’ remarks filed February 13, 2026, with respect to the rejection(s) of claim(s) 1, 8, 16 under 35 U.S.C. have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of newly found prior art Kim et al. (US 2023/0045971).
Examiner respectfully disagrees with Applicants’ assertion-“Thus, Xu only describes selecting a single precoding matrix W each time a downlink signal is received, and performing precoding for symbol streams based on the selected precoding matrix W”-for the same reasons detailed in the Office Action dated December 15, 2025. While it is true that Xu teaches in Section 0078 wherein the precoding matrix W is selected based on the on the uplink MIMO channel matrix, said uplink MIMO channel matrix can change or vary based on the fact that the characteristics of the channel can change thus leading to different precoding matrices.
Kim teaches the feature of a repeated transmission of an uplink signal a plurality of times in succession (Section 0236).

The applied reference has a common assignee with the instant application. Based upon the earlier effectively filed date of the reference, it constitutes prior art under 35 U.S.C. 102(a)(2).
This rejection under 35 U.S.C. 103 might be overcome by: (1) a showing under 37 CFR 1.130(a) that the subject matter disclosed in the reference was obtained directly or indirectly from the inventor or a joint inventor of this application and is thus not prior art in accordance with 35 U.S.C.102(b)(2)(A); (2) a showing under 37 CFR 1.130(b) of a prior public disclosure under 35 U.S.C. 102(b)(2)(B); or (3) a statement pursuant to 35 U.S.C. 102(b)(2)(C) establishing that, not later than the effective filing date of the claimed invention, the subject matter disclosed and the claimed invention were either owned by the same person or subject to an obligation of assignment to the same person or subject to a joint research agreement. See generally MPEP § 717.02.
Regarding Claim 19, The Ly combination teaches all of the claimed limitations recited in Claim 8. Ly further teaches the uplink signal is repeatedly transmitted (Section 0094, the TTIs available for repetitions will be used for uplink transmission).
Ly combination does not teach change the precoding matrix and the transmission power when the uplink signal is repeatedly transmitted, wherein the changed precoding matrix is randomly selected from among a plurality of precoding matrices, or selected based on a result of channel estimation, and wherein the changed transmission power is determined based on a path loss and a block error rate.
Bai further teaches change the precoding matrix when the uplink signal is transmitted (Section 0004, full duplex or half duplex renders a transmission of uplink signals), wherein the changed precoding matrix is randomly selected from among a plurality of precoding matrices, or selected based on a result of channel estimation (Section 0004, no channel estimation is required in order to select precoding matrices).
It would have been obvious to one of ordinary skill in the art prior to the effective filing date of the claimed invention to modify the system of Ly with the above features of Bai for the purpose of promoting higher reliability and lower latency duplex communications as taught by Bai.
Ly combination does not teach determine to change the transmission power when the uplink signal is transmitted; monitor a path loss in real time; change the transmission power based on the pathloss.
Farag, which also teaches wireless communications, teaches determine to change the transmission power when the uplink signal is transmitted (Section 0179, PLRS is monitored, a dynamic power control is taught in Section 0179 thus a determination to change the transmission power can occur when an uplink signal is transmitted); monitor a path loss in real time (Section 0179, PLRS is monitored); change the transmission power based on the pathloss (Section 0179 transmission power takes into account the MPR and thus will be adjusted based on said MPR).
It would have been obvious to one of ordinary skill in the art prior to the effective filing date of the claimed invention to modify the system of the Ly combination with the above features of Farag for the purpose of providing improved beam selection and tracking, which is a benefit of the beam measurement reporting taught in Farag.
Ly combination does not teach monitor a block error rate in real time; change the transmission power based on the BLER.
Rico Alvarino, which also teaches wireless communications, teaches monitor a block error rate in real time (Section 0069, looking to achieve a particular BLER); change the transmission power based on the BLER (Section 0069, transmission power takes into account the MPR and thus will be adjusted based on said MPR)
It would have been obvious to one of ordinary skill in the art prior to the effective filing date of the claimed invention to modify the system of the Ly combination with the above features of Rico Alvarino for the purpose of enabling a UE to autonomously modify one or more transmission parameters, other than a transmit power, for uplink communications after detecting a change in pathloss as taught by Rico Alvarino.
Regarding Claim 20, The Ly combination teaches all of the claimed limitations recited in Claim 19. Ly combination does not teach monitor a path loss and a block error rate in real time; change a maximum power reduction (MPR) value based on a result of the monitoring; and determine the changed transmission power obtained by subtracting the MPR value from a predetermined transmission power value.
Farag, which also teaches wireless communications, teaches monitor a path loss in real time (Section 0179, PLRS is monitored); change a maximum power reduction (MPR) value based on a result of the monitoring; and determine the changed transmission power obtained by subtracting the MPR value from a predetermined transmission power value (Section 0179, transmission power takes into account the MPR, which is effectively subtracting the MPR, and thus will be adjusted based on said MPR).
