DETAILED ACTION
This communication is in response to applicant’s response filed under 37 C.F.R. §1.111 in response to a non-final office action. Claims13, 20, 24, 28, and 30 have been amended. Claims 1-30 are subject to examination.
Response to Arguments
Applicants’ arguments filed 07/27/2026 have been fully considered but they are not persuasive for the following reasons:
Applicants’ Argument:
The applicant argues, on page 14 in substance that "Referring first to the "transmitting" feature of independent claim 1, in rejecting this feature, the Examiner cited paragraphs [0124], [0130]-[0133], [0144], [0145], and [0159] of Vejlgaard. As cited by the Examiner, these paragraphs generally disclose that "One UE broadcasts its CLI avoidance information (i.e., a resource on which the UE transmits a reference signal such as SRS and/or DMRS) and the other nearby UEs listen" (Vejlgaard, paragraph [0145]). However, while Vejlgaard discloses a UE broadcasting CLI avoidance information over a resource pool, Vejlgaard completely fails to disclose that the SRS and/or DMRS are transmitted on a transmit beam, that the transmission occurs during a beam training occasion, that the beam training occasion is shared among a plurality of UEs, or that the beam training occasion is specifically for transmitting beam training reference signals (BT-RS) for sidelink communications among the plurality of UEs. There is no mention whatsoever in Vejlgaard of transmit beams, beam training, or the like. Vejlgaard's resource pool is strictly dedicated to exchanging and monitoring CLI avoidance messages between UEs to mitigate interference, not as a shared beam training occasion for transmitting beam training reference signals for sidelink communications among the UEs."
Examiner’s Response:
The examiner respectfully disagrees. Vejlgaard teaches [0124] The SRS and/or DMRS information comprises an indication of the resource (time, frequency) used by UE1 to transmit. UE scans for proximity UEs by exchange SRS/DMRS information for CLI measurement purposes and measures CLI from dedicated UE with known SRS/DMRS information reports from active and nearby UEs to its serving gNB. The self- interference management reference signal when not defined is construed as any kind of signal, as in Vejlgaard this signal is a type of indication of the resource (time, frequency) transmits on SRS and or DMRS which examiner is construing that the indication of the resource (time, frequency) is the self- interference management reference signal on the first transmit beam that is transmitted for sidelink communications to perform the sidelink communication to inform (get informed) on resources to transmit SRS and/or DMRS. However, claim 1 merely recites transmitting, by a transmitter... of the UE on a transmit beam, a self-interference management reference signal (SIM-RS) during a first beam training occasion...
Applicants’ Argument:
The applicant argues, on page 14 in substance that "However, Vejlgaard explicitly describes CLI as interference occurring between two different UEs, rather than self-interference measured at a single UE. As stated in Vejlgaard, and as cited by the Examiner, "Nearby UE (e.g. UE2) detects UEl and measures CLI" (Vejlgaard, paragraph [0127]). This clearly describes a scenario where a second, separate UE (UE2) measures interference originating from a first UE (UE1). In contrast, independent claim 1 requires a single transmitter UE to measure self-interference at its own receiver TRxP, where the self-interference is caused by the same transmitter UE's own transmission from its transmitter TRxP. Because Vejlgaard relies on a second, separate UE to measure interference, it fails to disclose a single UE measuring its own self-interference. Accordingly, Vejlgaard does not disclose or suggest the feature of "measuring, by a receiver TRxP of the transmitter UE on a receive beam, self-interference at the receiver TRxP caused by transmission of the SIM-RS by the transmitter TRxP," as recited in independent claim 1, much less "in as complete detail as is contained in the ... claim."”
Examiner’s Response:
The examiner respectfully disagrees. Vejlgaard teaches in [0124-0128] the SRS and/or DMRS information comprises an indication of the resource (time, frequency) used by UE1 to transmit. [0127] Nearby UE (e.g. UE2) detects UE1 and measures CLI using RSRP (knowing SRS/DMRS information) [0128] UE2 reports the CLI to gNB2. When UE2 detects UE1 based on the information comprising the indication of the resource (time, frequency) SRS/DMRS information, UE2 reports the interference caused by the transmission of the information comprised of the resource (time, frequency) used by UE1 which examiner is construing that cross link interference (CLI) occurred at the receiver UE2 is the self-interference at the receiver which was reported to gNB2. Vejlgaard further teaches in [0141] The defined resource pool configurations may be orthogonal to each other (as depicted in FIG. 3, left side). The gNBs negotiate which group of resources is to be used for the sidelink communication. However, claim 1 merely recites ... measuring, by a receiver TRxP of the transmitter UE on a receive beam...
Regarding all other arguments presented by applicant, the arguments are substantially the same as those which have already been addressed above and in the interest of brevity; the examiner directs the applicant to those responses above.
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.

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);

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-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]).
Conclusion
