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 April 8, 2026 have been fully considered but they are not persuasive. Regarding rejection of claims 1-5, 8-13, 16, 17, 19 and 20, Applicant argues that cited sections of Mahama et al. (US 2024/0284208) are not described/supported by provisional application (US 63/485265), the cited sections of Mahama et al. are not entitled to the earlier filing date of the provisional, and therefore the cited sections of Mahama et al. do not qualify as prior art. Examiner respectfully disagrees. For at least the following claims of the instant application, citations from Mahama et al. are supported by the provisional application. These claims therefore remain rejected over Mahama et al. as originally outlined in the non-final rejection.
For rejection of claims 1 and 20, cited sections of Mahama et al. include:

This indication is provided by a higher layer parameter, which is a control message sent from the base station 702 to the UE 704, informing it of the specific slots where measurements should not be taken).
Regarding claim 10, Mahama et al. disclose wherein the one or more processors are further configured to drop one or more other uplink transmissions in accordance with the rule or the configuration (Paragraph 92, To inform the UE 706/708 about when to skip the SRS transmissions, the base station 702 uses a higher layer parameter. This parameter is communicated to the UEs via control signaling, such as Radio Resource Control (RRC) messages. The parameter indicates the specific sets of slots where SRS transmissions should not occur; Paragraph 125, the UE 704 may be configured to skip the CLI measurements to prevent inaccurate interference assessments. To facilitate this, the base station 702 would indicate to UE 704 when to skip the CLI measurements. This indication is provided by a higher layer parameter, which is a control message sent from the base station 702 to the UE 704, informing it of the specific slots where measurements should not be taken).
Regarding claim 11, Mahama et al. disclose wherein the one or more processors are further configured to receive a cross-link interference measurement resource for all uplink sub-bands in one or more select SBFD resources of a plurality of SBFD resources (Paragraph 116, in the SBFD slots 721, 722 and 723, the UE 704 can be configured by the base station 702 to measure cross link interference (CLI) over RB groups 970, 980 and 990 within its UL subband 731. These RB groups for CLI measurement follow an RBG or resource block group level configuration. In one configuration, each RB group consists of multiples of 4 RBs. As such, in this example, the RB groups 970, 980 and 990 over which the UE 704 measures CLI are made up of multiples of 4 RBs. For example, each group could contain 4 RBs, 8 RBs, 12 RBs etc. This allows frequency differentiation so that CLI can be measured separately on each group; Paragraph 110, the base station 702 re configures the CLI-RSSI measurement resources to uplink resources during the UE 704's downlink reception phase. More specifically, the UE 704 utilizes the unused UL subband 731 for interference measurement while receiving downlink data).
Regarding claim 12, Mahama et al. disclose wherein the one or more processors are further configured to obtain a rule or configuration that enables cross-link interference measurement resource reception within the uplink sub-band of the SBFD resource without a configured sounding reference signal transmission, a configured physical uplink control channel transmission, or a higher priority uplink transmission (Paragraph 92, To inform the UE 706/708 about when to skip the SRS transmissions, the base station 702 uses a higher layer parameter. This parameter is communicated to the UEs via control signaling, such as Radio Resource Control (RRC) messages. The parameter indicates the specific sets of slots where SRS transmissions should not occur; Paragraph 125, the UE 704 may be configured to skip the CLI measurements to prevent inaccurate interference assessments. To facilitate this, the base station 702 would indicate to UE 704 when to skip the CLI measurements. This indication is provided by a higher layer parameter, which is a control message sent from the base station 702 to the UE 704, informing it of the specific slots where measurements should not be taken).
Regarding claim 13, Mahama et al. disclose wherein the one or more processors are further configured to drop one or more lower priority uplink transmissions in accordance with the rule or the configuration (Paragraphs 92 and 125, skipping SRS transmissions based on RRC message from base station).
Regarding claim 16, Mahama et al. disclose wherein the one or more processors, to measure the RSSI within the downlink sub-band of the SBFD resource (Paragraphs 107-109 disclose CLI-RSSI measurement during downlink subbands 732 and 733 of the SBFD resource without the ability to differentiate between different sources of interference and their respective interference levels; Paragraph 110, instead of configuring the CLI-RSSI measurement resources on downlink resources…), the RSSI within the uplink sub-band of the SBFD resource (Paragraph 105, the UE 704, which is configured as a downlink-centric device, is equipped with CLI-RSSI measurement resources 910 to assess the interference levels in the UL subband 731 during SBFD operation; Paragraphs 110-112, CLI-RSSI measurements with uplink subband 731 of the SBFD resource based on granularity configuration), or the RSRP within the uplink sub-band of the SBFD resource, are configured to measure the RSSI within the downlink sub-band of the SBFD resource (Paragraphs 107-109 disclose CLI-RSSI measurement during downlink subbands 732 and 733 of the SBFD resource without the ability to differentiate between different sources of interference and their respective interference levels; Paragraph 110, instead of configuring the CLI-RSSI measurement resources on downlink resources…), the RSSI within the uplink sub-band of the SBFD resource (Paragraph 105, the UE 704, which is configured as a downlink-centric device, is equipped with CLI-RSSI measurement resources 910 to assess the interference levels in the UL subband 731 during SBFD operation; Paragraphs 110-112, CLI-RSSI measurements with uplink subband 731 of the SBFD resource based on granularity configuration), or the RSRP within the uplink sub-band of the SBFD resource based at least in part on the cross-link interference being associated with a Layer 1, Layer 2, or Layer 3 reporting framework (Paragraph 43, RRC layer functionality associated with…measurement reporting; Paragraph 39, Layer 3 includes a radio resource control (RRC) layer).
Regarding claim 17, Mahama et al. disclose wherein the one or more processors are further configured to receive a radio resource control (RRC) parameter that indicates whether the UE is to measure the RSSI (Paragraph 71, The base station 702 determines an SRS configuration 810 and notifies the SRS configuration 810 to the UEs 706 and/or 708 via, e.g., Radio Resource Control (RRC) messages; Paragraph 105, The UE 704, which is configured as a downlink-centric device, is equipped with CLI-RSSI measurement resources 910 to assess the interference levels in the UL subband 731 during SBFD operation. These resources are allocated by the base station 702 and are defined by an information element called MeasObjectCLI, which provides the RSSI-ResourceConfigCLI. The configuration allows for a granularity; Paragraph 110, In a second approach, instead of configuring the CLI-RSSI measurement resources on downlink resources, the base station 702 re configures the CLI-RSSI measurement resources to uplink resources during the UE 704's downlink reception phase) within the downlink sub-band of the SBFD resource (Paragraphs 107-109 disclose CLI-RSSI measurement during downlink subbands 732 and 733 of the SBFD resource without the ability to differentiate between different sources of interference and their respective interference levels; Paragraph 110, instead of configuring the CLI-RSSI measurement resources on downlink resources…), the RSSI within the uplink sub-band of the SBFD resource (Paragraph 105, the UE 704, which is configured as a downlink-centric device, is equipped with CLI-RSSI measurement resources 910 to assess the interference levels in the UL subband 731 during SBFD operation; Paragraphs 110-112, CLI-RSSI measurements with uplink subband 731 of the SBFD resource based on granularity configuration), or the RSRP within the uplink sub-band of the SBFD resource.
Regarding claim 19, Mahama et al. disclose an apparatus for wireless communication at a network node (Figure 2, base station 210), comprising:

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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 6 is/are rejected under 35 U.S.C. 103 as being unpatentable over Mahama et al. as applied to claim 1 above, and further in view of Ibrahim et al. (US 2022/0014954).
Regarding claim 6, Mahama et al. disclose the claimed invention above but do not disclose the following limitations that are disclosed by Ibrahim et al.: wherein the one or more processors, to receive the cross-link interference measurement resource configuration, are configured to receive a single cross-link interference measurement resource configuration that indicates to measure the RSSI across all uplink sub-bands and all downlink sub-bands of the SBFD resource (Ibrahim et al., Paragraph 87, For full-duplex communication, the base station may configure the CSI-IM resources to extend in both the uplink and downlink portions of DL BWP in a full-duplex slot. The CSI-IM resources may enable the UE 2, which is full-duplex aware or full-duplex capable, to measure different components of interference; Paragraph 90, In the SBFD example 1210, the CSI-IM resources 1215 may include downlink portions 1217 and 1218 that may be subject to self-interference from the CLI leakage and an uplink portion 1216 that may mainly include the CLI of self-interference… For full-duplex communication, a base station may configure CSI-IM resources to extend in both the uplink and downlink portions of DL BWP in a full-duplex slot. The CSI-IM resources may enable a full-duplex UE1 to measure different components of interference) and to report a total RSSI measurement across all uplink sub-bands and all downlink sub-bands of the SBFD resource (Ibrahim et al., Paragraph 95, the victim UE2 may measure the interference in the two configured CSI-IM resources 1410 and 1420 and report, to the base station, the one or two CLI reports including the RSSI values measured in the two configured CSI-IM resources 1410 and 1420).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Mahama et al. with the cited disclosure from Ibrahim et al. in order to measure different components of interference (Ibrahim et al., Paragraph 87).
Claim(s) 18 is/are rejected under 35 U.S.C. 103 as being unpatentable over Mahama et al. as applied to claim 1 above, and further in view of Pedersen et al. (US 2022/0140959).
Regarding claim 18, Mahama et al. disclose the claimed invention above but do not disclose the following limitations that are disclosed by Pedersen et al.: wherein the one or more processors are further configured to perform a wideband cross-link interference measurement based at least in part on not being configured with a radio resource control parameter that indicates whether the UE is to measure the RSSI within the downlink sub-band of the SBFD resource, the RSSI within the uplink sub-band of the SBFD resource, or the RSRP within the uplink sub-band of the SBFD resource (Pedersen et al., Paragraph 38, the at least one CLI measurement framework object may be associated with RRC signaling according to 3GPP TS 38.331 (RRC signaling). For example, RRC signaling may define at least one PHY/MAC procedure for CLI reporting. Such information may define whether the UE shall use implicit or explicit signaling of UE CLI measurements/information back to the network, as well as whether UE CLI measurements should be wideband or per subband; Paragraph 42, At 401, NE 410 may transmit at least one message to UE 420. In some example embodiments, the at least one message may configure UE 420 to measure CLI (such as RSSI or SRS-RSRP) and/or UE interference measurements, such as those based on CSI-IM resource or NZP CSI-RS resources for interference measurement. For example, such measurements may be configured to be wideband or frequency selective, such as per sub-band).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Mahama et al. with the cited disclosure from Pedersen et al. in order to provide semi-dynamic information of the UE CLI experience to the network with limited complexity (Pedersen et al., Paragraph 31) and to avoid scheduling UEs in subbands where they experience harmful UE-2-UE CLI conditions (Pedersen et al, Paragraph 32).
Allowable Subject Matter
Claims 7, 14 and 15 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter:
Regarding claim 7, the prior art does not disclose or adequately suggest receiving RSSI measurements within first and second frequency resource portions of the uplink sub-band of the SBFD resource, receiving RSSI measurements within first and second frequency resource portions of each downlink sub-band of the SBFD resource, and then reporting the RSSI measurements across all uplink sub-band and all downlink sub-bands of the SBFD resource;
Regarding claim 14 (with further dependent claim 15), the prior art discloses the SBFD resource including an uplink sub-band that is between two other sub-band that are outside of the uplink sub-band (See Mahama et al., Figure 7 and paragraph 64, the SBFD subband is configured with a DUD pattern. More specifically, a SBFD slot 730 includes an UL subband 731 at the center of the channel bandwidth, two DL subbands 732 and 733 on either side of the channel bandwidth, and GB subbands 734 and 735 separating the DL subbands 732 and 733 from the UL subband 731), but does not disclose or adequately suggest that transmission by the other UE is performed within at least one other sub-band of the two other sub-bands that are outside of the uplink sub-band.
