Office Action

§102 §103
DETAILED ACTION 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and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114.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 05, 2026 has been entered, claims 1-30 are pending and ready for examination. Response to Arguments Applicant’s arguments with respect to the claims have been considered but are moot in view of the new grounds of rejection. 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, 16, 29 and 30 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Vejlgaard et al. (Vejlgaard hereafter) (US 20220030522 A1).

Claim Rejections - 35 USC § 103 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 2-7, 13-15, 17-22, and 28 are rejected under 35 U.S.C. 103 as being unpatentable over Vejlgaard as applied to claims 1 and 16 above, and further in view of Byun et al. (Byun hereafter) (US 20190260485 A1) (IDS provided). Regarding claims 2 and 17 Vejlgaard teaches, The claims 1 and 16, Vejlgaard fails to explicitly teach, wherein: the transmitter UE transmits the SIM-RS on a first subset of time and frequency resources of the first beam training occasion, and a second subset of time and frequency resources of the first beam training occasion are available for transmission of BT-RS However, in the same field of endeavor Byun teaches, wherein: the transmitter UE transmits the SIM-RS on a first subset of time and frequency resources of the first beam training occasion, and a second subset of time and frequency resources of the first beam training occasion are available for transmission of BT-RS (Byun; [0107] as shown in FIG. 7, a UE transmits signals simultaneously to different UEs in a multiplexed manner If three UEs intend to establish a communication link with each adjacent UE as shown in FIG. 7, one transmission resource and two reception resources shall be allocated to each UE.). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Regarding claims 3 and 18 Vejlgaard-Byun teaches, The claims 2 and 17, Vejlgaard fails to explicitly teach, wherein the first subset of time and frequency resources are orthogonal to the second subset of time and frequency resources. Byun further teaches, wherein the first subset of time and frequency resources are orthogonal to the second subset of time and frequency resources (Byun; [0107-109] as shown in FIG. 7, a UE transmits signals simultaneously to different UEs in a multiplexed manner If three UEs intend to establish a communication link with each adjacent UE as shown in FIG. 7, one transmission resource and two reception resources shall be allocated to each UE... inter-communication group resource and intra-communication group resource are resources orthogonal to each other. ). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Regarding claims 4 and 19 Vejlgaard-Byun teaches, The claims 2 and 17, Vejlgaard fails to explicitly teach, wherein the first subset of time and frequency resources are interleaved with the second subset of time and frequency resources. Byun further teaches, wherein the first subset of time and frequency resources are interleaved with the second subset of time and frequency resources (Byun; [0247] In step S2460, the UE may transmit information about an RU group which transmits a reference signal for periodically measuring the inter-RU interference to the eNB.). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Regarding claims 5 and 20 Vejlgaard-Byun teaches, The claims 2 and 17, Vejlgaard fails to explicitly teach, wherein the first subset of time and frequency resources are: selected by the transmitter UE, configured by a serving base station of the transmitter UE, specified in a wireless communications standard, or any combination thereof. Byun further teaches, wherein the first subset of time and frequency resources are: selected by the transmitter UE (Byun; [0107] UE transmits signals simultaneously to different UEs), configured by a serving base station of the transmitter UE (Byun; [0071] Data is transmitted from the network to the UE through a downlink transport), specified in a wireless communications standard, or any combination thereof. It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Regarding claims 6 and 21 Vejlgaard-Byun teaches, The claims 2 and 17, Vejlgaard fails to explicitly teach, further comprising: transmitting, to at least one receiver UE of the plurality of UEs, a message indicating that the transmitter UE is transmitting the SIM-RS on the first subset of time and frequency resources to prevent the at least one receiver UE from attempting to establish a sidelink with the transmitter UE based on the SIM-RS Byun further teaches, further comprising: transmitting, to at least one receiver UE of the plurality of UEs, a message indicating that the transmitter UE is transmitting the SIM-RS on the first subset of time and frequency resources to prevent the at least one receiver UE from attempting to establish a sidelink with the transmitter UE based on the SIM-RS (Byun; [0071] Data is transmitted from the network to the UE through a downlink transport channel Examples of the downlink transport channel include a broadcast channel (BCH) for transmitting system information and a downlink-shared channel (SCH) for transmitting user traffic or control messages. [0073] The sidelink uses a UL resource and physical channel structure similarly to UL transmission. Sidelink transmission uses the same basic transmission scheme as the UL transmission scheme.). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Regarding claims 7 and 22 Vejlgaard-Byun teaches, The claims 6 and 21, Vejlgaard fails to explicitly teach, wherein the message is a radio resource control (RRC) message. Byun further teaches, wherein the message is a radio resource control (RRC) message (Byun; [0070] When an RRC connection is established between an RRC layer of the UE and an RRC layer of the network, the UE is in an RRC connected state, and otherwise the UE is in an RRC idle state.). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Regarding claims 13 and 28 Vejlgaard teaches, The claims 1 and 16, Vejlgaard fails to explicitly teach, wherein a reference signal sequence of the SIM-RS is different than a reference signal sequency of the BT-RS. Byun further teaches, wherein a reference signal sequence of the SIM-RS is different than a reference signal sequency of the BT-RS (Byun; [0205] UE transmits a CSI-RS such that the UE can measure self-interference while receiving a CSI-RS transmitted from an eNB as an embodiment. Alternatively, this may be represented as a design in which the UE transmits an SRS when the eNB transmits the CSI-RS, and the SRS is orthogonal to the CSI-RS.). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Regarding claims 14 Vejlgaard teaches, The method of claim 1, Vejlgaard fails to explicitly teach, wherein the transmitter UE communicates via the transmitter TRxP and the receiver TRxP using single frequency full duplex (SFDD). Byun further teaches, wherein the transmitter UE communicates via the transmitter TRxP and the receiver TRxP using single frequency full duplex (SFDD) (Byun; [0202] to separately measure self-interference when antenna 1 transmits a signal and antenna 2 receives a signal and self-interference when antenna 2 transmits a signal and antenna 1 receives a signal.). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Regarding claim 15 Vejlgaard-Byun teaches, The method of claim 14, Vejlgaard fails to explicitly teach, wherein the transmitter TRxP and the receiver TRxP are spatially separated. Byun further teaches, wherein the transmitter TRxP and the receiver TRxP are spatially separated (Byun; [0100] The SDD considered in the present specification is a technique in which each antenna of a UE is subjected to space division to independently operate a communication link of each antenna. In order to independently operate the communication link for each antenna,). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Claims 8 and 23 are rejected under 35 U.S.C. 103 as being unpatentable over Vejlgaard-Byun as applied to claims 6 and 21 above, and further in view of Matsumura et al. (Matsumura hereafter) (US 20180083679 A1). Regarding claims 8 and 23 Vejlgaard-Byun teaches, The claims 6 and 21, Vejlgaard-Byun fails to explicitly teach, wherein the message further includes: a transmission configuration indicator (TCI) state identifier of the transmit beam, a quasi-co-location (QCL) relation of the transmit beam, or any combination thereof. However, in the same field of endeavor Matsumura teaches, wherein the message further includes: a transmission configuration indicator (TCI) state identifier of the transmit beam, a quasi-co-location (QCL) relation of the transmit beam, or any combination thereof (Matsumura; [0029] The TCI state is information about Quasi-Co-Location (QCL) of the signal/channel, and may be called a spatial reception parameter, spatial relation information (SRI) and the like. The TCI state may be configured on a UE for each channel or for each signal.). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard-Byun to include the above recited limitations as taught by Matsumura in order to determine at least one of a transmission beam (Tx beam) and a reception beam (Rx beam) of the signal/channel (Matsumura; [0038]). Claims 9-12 and 24-27 are rejected under 35 U.S.C. 103 as being unpatentable over Vejlgaard- Byun as applied to claims 2 and 17 above, and further in view of Lim et al. (Lim hereafter) (US 2018008 3679 A1) (IDS provided). Regarding claim 9 and 24 Vejlgaard-Byun teaches, The claims 2 and 17, Vejlgaard fails to explicitly teach, further comprising: receiving, from at least one receiver UE of the plurality of UEs, a measurement report of the SIM-RS. nullforming one or more sidelobes of the transmit beam for transmission of a second reference signal during a second beam training occasion based on the measurement report and the self-interference measured at the receiver. repeating the transmitting, measuring, receiving, and nullforming until self-interference from the transmitter TRxP is minimized Byun further teaches, further comprising: receiving, from at least one receiver UE of the plurality of UEs, a measurement report of the SIM-RS (Byun; to select a half-duplex radio (HDR) mode and a full duplex radio (FDR) mode, a UE needs to perform periodic channel measurement. Here, channel measurement includes not only channel measurement between an eNB and the UE and self-interference measurement between antennas in the UE); It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Vejlgaard-Byun fails to explicitly teach, nullforming one or more sidelobes of the transmit beam for transmission of a second reference signal during a second beam training occasion based on the measurement report and the self-interference measured at the receiver. repeating the transmitting, measuring, receiving, and nullforming until self-interference from the transmitter TRxP is minimized However, in the same field of endeavor Lim teaches, nullforming one or more sidelobes of the transmit beam for transmission of a second reference signal during a second beam training occasion based on the measurement report and the self-interference measured at the receiver TRxP (Lim; [0194] FIG. 14, and a beam nulling process considering self-interference in a communication system supporting a beamforming scheme [0196] FIG. 15, a transmission/reception beam nulling scheme is applied toward a transmission leakage signal direction and a reflection signal direction. In a case that the transmission/reception beam nulling scheme is applied,) (See Fig. 16); and repeating the transmitting, measuring, receiving, and nullforming until self-interference from the transmitter TRxP is minimized (Lim; [0220] So, self-interference suppression may be increased through a beam nulling process which is based on a self-interference direction-of-arrival (DoA) as described in FIG. 17.). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard-Byun to include the above recited limitations as taught by Lim in order to operating a full-duplex scheme in a communication system (Lim; [0207]). Regarding claims 10 and 25 Vejlgaard-Byun-Lim teaches, The claims 9 and 24, Vejlgaard-Lim fails to explicitly teach, wherein the second reference signal is a SIM-RS or a BT-RS. Byun further teaches, wherein the second reference signal is a SIM-RS or a BT-RS (Byun; [0204] UE transmits a reference signal (RS) for self-interference measurement through some RUs and simultaneously receives an eNB RS and an RS for self-interference measurement through some RUs.). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard-Lim to include the above recited limitations as taught by Byun in order to measuring inter-RU interference (Byun; [0022]). Regarding claims 11 and 26 Vejlgaard-Byun-Lim teaches, The claims 9 and 24, Vejlgaard further teaches, wherein the measurement report is received: per TCI state of the transmit beam, or per TCI state and measurement instance of the transmit beam (Vejlgaard; [0157] Only if the gNB triggers the CLI avoidance exchange, the UEs served by this gNB monitor the CLI avoidance resource pool and broadcast their own CLI related information). Claims 12 and 27 are rejected under 35 U.S.C. 103 as being unpatentable over Vejlgaard as applied to claims 1 and 16 above, and further in view of Lim et al. (Lim hereafter) (US 20180083679 A1) (IDS provided). Regarding claims 12 and 27 Vejlgaard teaches, The claims 1 and 16, Vejlgaard fails to explicitly teach, further comprising: nullforming one or more sidelobes of the transmit beam for transmission of a second reference signal during a second beam training occasion based on the self-interference measured at the receiver TRxP repeating the transmitting, measuring, and nullforming until self-interference from the transmitter TRxP is minimized. Lim further teaches, nullforming one or more sidelobes of the transmit beam for transmission of a second reference signal during a second beam training occasion based on the self-interference measured at the receiver TRxP (Lim; [0068] for operating a full-duplex scheme based on a beam selection/nulling scheme in a communication system supporting a beamforming scheme.); and repeating the transmitting, measuring, and nullforming until self-interference from the transmitter TRxP is minimized (Lim; [0219] A self-interference DoA table updating process as described in FIG. 17 is a process for verifying a self-interference DoA table which was generated already using a full-duplex characteristic, and whether a self-interference DoA is changed is check by receiving a signal based on the self-interference DoA table which was generated already.[0220] So, self-interference suppression may be increased through a beam nulling process). It would have been obvious to one of ordinary skilled in the art before the effective filing date to create the invention of Vejlgaard to include the above recited limitations as taught by Lim in order to operating a full-duplex scheme in a communication system (Lim; [0207]).
