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 .
Claim Rejections - 35 USC § 103
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 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 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.
Claim(s) 1-3,5-24,26-32 is/are rejected under 35 U.S.C. 103 as being unpatentable over Park et al (US 12108267 B2) hereinafter as Park in view of Kim et al (US 11968641 B2) hereinafter as Kim.
Regarding claim(s) 1,21,29-30, Park discloses apparatus for wireless communication at a user equipment (UE), comprising: a processor; memory coupled with the processor; and instructions stored in the memory and executable by the processor (See Fig(s). 20) to cause the apparatus to:
receive a channel state information (CSI) report configuration that indicates a dedicated UE-to-UE cross-link interference (CLI) resource as an additional interference measurement resource (IMR) (See Fig(s). 8 step S810, See Fig(s). 9, See ¶ 23, The operations may include transmitting, to a first user equipment (UE), channel state information (CSI)-related first configuration information… The first configuration information may include information related to the cross-link interference, and the second configuration information may include a configuration for a reference signal related to cross-link interference measurement of the first UE…. See ¶ 233, The victim UE may measure the CLI based on information/using IMR (e.g., ZP/NZP CSI-RS)-related information received from the base station).
wherein the CSI report configuration indicates measurement resources of: a non-zero-power (NZP) channel state information reference signal (CSI-RS) resource (See ¶ 127, The CSI resource configuration-related information defines a group including at least one of a non-zero power (NZP) CSI-RS resource set,) or resource set for channel measurement;
a CSI-RS resource or resource set for interference measurement (See ¶ 127, CSI-RS resource set,;
an NZP CSI-RS resource or resource set for interference management (See ¶ 127, the CSI-RS resource set list may include at least one of a NZP CSI-RS resource set); and
a CLI resource or resource set for UE-to-UE CLI measurement (See Fig(s). 16, See ¶ 297, an example signaling procedure between a base station and a UE to report CSI including a report for CLI ).
Park fails to disclose - transmit, based at least in part on the CSI report configuration, a CSI report that implicitly captures CLI in a CSI report quantity of the CSI report.
Kim discloses - transmit, based at least in part on the CSI report configuration, a CSI report that implicitly captures CLI in a CSI report quantity of the CSI report (See ¶ 307, In terms of measurement reporting, there is a tradeoff between reporting overhead (i.e., periodicity and/or quantity and/or quality) and system performance Similar to current RSRP/RSRQ reports, some event driven reports may be considered for UE-to-UE CLI measurement reporting with low complexity.).
Quantity reporting helps to identify quantities of the RSSI, RSRP, or RSRQ measurements to be included in the CLI report.
Thus, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention, to incorporate the teachings of Kim within Park, so as to have quantity reporting to identify quantities of the RSSI, RSRP, or RSRQ measurements to be included in the CLI report.
Further with regards to claim 21, Park discloses a network node that performs the mirrored steps of claim 1 (See Fig(s). 9, 20).
Regarding claim(s) 2,23,31, Park discloses wherein one or more of: interference from one or more IMRs to measure intra-cell cross beam interference, inter cell downlink interference (See ¶ 234, As another example, the victim UE may also perform interference measurement/calculation with, e.g., reference signal received power (RSRP). ) , or interference from the dedicated UE-to-UE CLI resource is captured in one or more CSI metrics associated with the CSI report quantity of the CSI report.
Regarding claim(s) 3,24, Park discloses wherein the one or more CSI metrics include one or more of: a layer 1 signal-to-interference-plus-noise ratio (L1-SINR) (See ¶ 238, interference control in a severe CLI scenario. However, precise SINR measurement requires an IMR resource for interference measurement and background noise as well as an IMR resource for CLI-RS.) , a channel quality indicator (CQI), a precoding matrix indicator (PMI), or a rank indicator (RI).
Regarding claim(s) 5,26, Park discloses wherein the CLI resource or resource set is associated with a CLI reference signal received power (RSRP) resource (See ¶ 17, the report on the measured cross-link interference may include a reference signal received power (RSRP) or a received signal strength indicator (RSSI) for the cross-link interference.) or a CLI received signal strength indicator (RSSI) resource, and the CLI RSRP is based at least in part on a sounding reference signal (SRS) resource information element (IE) and the CLI RSSI resource is based at least in part on an RSSI resource IE (See Fig(s). 10-11, See ¶ 212-215).
Regarding claim(s) 6,27, Park discloses wherein the CLI resource or resource set is associated with the CSI-RS resource for interference measurement (See ¶ 127) or an NZP CSI-RS resource or resource set for interference management, and a CLI received signal strength indicator (RSSI) resource or a CLI RSSI resource is indicated using an information element (IE) associated with the CSI-RS resource for interference measurement or the NZP CSI-RS resource or resource set for interference management (See Fig(s). 10, interference measurement with resource element).
Regarding claim(s) 7,28, Park discloses wherein the CSI report configuration indicates a CLI sounding reference signal (SRS) resource as a dedicated IMR to measure UE-to-UE CLI to be captured using one or more CSI metrics (See Fig(s). 10, See ¶ 212, perform UL interference measurement, a new IMR pattern matching the pattern of RS (e.g., SRS-sounding reference signal) used for UL interference measurement is needed. In other words, when the SRS is used as the UL RS, it is transmitted as a pattern of comb 2 or comb 4 within a given set bandwidth and, given this, a new IMR pattern for CLI measurement may be configured.)
Regarding claim(s) 8, Kim discloses wherein the CLI SRS resource is a periodic CLI SRS resource, a semi-persistent CLI SRS resource, or an aperiodic CLI SRS resource (See ¶ 186). Reasons for combining same as claim 1.

Regarding claim(s) 14, Park discloses wherein transmitting the CSI report comprises transmitting two CSI reports using two CSI report configurations, wherein a first CSI report of the two CSI reports is using one or more CSI metrics capturing the CLI (See ¶ 21-22), and a second CSI report of the two CSI reports is using one or more CSI metrics without capturing the CLI (See ¶ 248, the time domain behavior of the existing CSI reporting that does not consider CLI and the time domain behavior of the CLI reporting that considers CLI may be set to differ from each other.).
