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 .
Response to Arguments
Applicant's arguments filed June 2, 2026 have been fully considered but they are not persuasive.
Regarding Applicants argument-For example, paragraphs 76-78 of Xu repeatedly state that the UE sends a sounding reference signal or pilot to the Node B, or that the Node B sends a downlink reference signal or common pilot to the UE. The Node B or the UE then estimates the downlink MIMO channel response based on the reference signal or pilot, obtains an uplink MIMO channel matrix from the estimated MIMO downlink matrix using reciprocity, and then selects a single precoding matrix based on the uplink MIMO channel matrix. The uplink MIMO channel matrix does not change until another downlink signal or pilot starts a new estimation of the downlink MIMO channel response-While it may be true that the uplink MIMO channel matrix in Xu does not change until another downlink signal or pilot starts a new estimation said estimation can lead to a different uplink MIMO channel matrix multiple times thus leading to different or multiple precoding matrices.
Kim teaches in Section 0234 that the UE can receive DC1 and DC2 in a DCI transmission through the PDCCH which leads to a repeated transmission of an uplink signal a plurality of times in succession (Section 0236). This can occur before another DCI is transmitted.

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 a maximum power reduction (MPR) value based on a result of the monitoring; and transmit the uplink signal using the changed transmission power obtained by subtracting the MPR value from a predetermined transmission power value (Section 0069, transmission power takes into account the MPR, which is effectively subtracting 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 in view of Xu in view of Kim in view of Farag 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.
Claims 19, 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Ly et al. (US 2022/0361198) in view of Xu et al. (US 2009/0046800) in view of Kim et al. (US 2023/0045971), as applied to Claim 8 set forth above, and further in view of Bai et al. (US 2022/0109550) in view of Farag et al. (US 2022/0416977) in view of Rico Alvarino et al. (US 2021/0250871)
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 in view of Xu in view of Kim 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 in view of Xu in view of Kim 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 in view of Xu in view of Kim with the above features of Bai for the purpose of promoting higher reliability and lower latency duplex communications as taught by Bai.
Ly in view of Xu in view of Kim in view of Bai 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 in view of Xu in view of Kim in view of Bai 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 in view of Xu in view of Kim in view of Bai in view of Farag 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 in view of Xu in view of Kim in view of Bai in view of Farag 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 in view of Xu in view of Kim in view of Bai in view of Farag in view of Rico Alvarino teaches all of the claimed limitations recited in Claim 19. Ly in view of Xu in view of Kim in view of Bai in view of Farag in view of Rico Alvarino 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).
