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 of this title, 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.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 1 – 7 are rejected under 35 U.S.C. 103 as being unpatentable over LIU et al. (LIU hereinafter referred to LIU) (US 2021/0212071 A1) in view of Qualcomm ("CR on 38.214 PDSCH resource mapping", R1-2002840, 3GPP TSG RAN WG1 Meeting #100bis, e-Meeting, April 20th – 30th, 2020) (cited in IDS).
Regarding claim 1, LIU teaches (Title, RESOURCE CONFIGURATION METHOD AND COMMUNICATIONS APPARATUS) a user equipment (UE) (Fig.10 and [0413], communications apparatus 1000 is a terminal device), comprising:
reception circuitry (Fig.10 and [0414], communications module 1002) configured to receive ([0416], The communications module 1002 is configured to perform step 402, step 404 shown in FIG. 4), from a base station, a first radio resource control (RRC) parameter indicating first one or more zero power channel state information reference signal (ZP CSI-RS) resource sets and a second RRC parameter indicating second one or more ZP CSI-RS resource sets (Fig.4, step 402 and step 403. [0251], base station A sends a plurality of ZP CSI-RS resource sets and configuration information of a ZP CSI-RS resource in each ZP CSI-RS resource set to the terminal device A through higher layer signaling, e.g., through radio resource control (RRC) signaling; [0301], the first resource set is the ZP CSI-RS resource set 1 and the second resource set is the ZP CSI-RS resource set 2. Here, a first ZP CSI-RS resource set and a second ZP CSI-RS resource set are received by a terminal/ UE through RRC signaling; therefore, it is obvious that a first RRC indicates ZP CSI-RS resource set 1 and a second RRC indicates ZP CSI-RS resource set 2), and to receive a DCI format (Fig.4, step 404. [0302], terminal device A receives the DCI) scheduling a physical downlink shared channel (PDSCH) ([0346], (PDSCH resource allocated to the terminal device A is indicated through the DCI); and
control circuitry (Fig.10 and [0414], processing module 1001) configured to:
determine overlapped with REs of the first one or more ZP CSI-RS resource sets ([0276], N codewords overlaps with any resource element RE in the first resource set; overlapped RE) or REs of the second one or more ZP CSI-RS resource sets as available REs for the PDSCH (Due to alternative language “or” in the claim examiner addresses one limitation only);
determine one or more overlapped with REs of the second one or more ZP CSI-RS resource sets ([0276], N codewords overlaps with any RE in the second resource set; overlapped RE), at least based on a DCI field in the DCI (Table 1 and [0255], an indication field in the DCI to indicate the enabled ZP CSI-RS resource set; different ZP CSI-RS resource sets are dynamically selected by indicating different state values of the indication field. As shown in Table 1); and
determine one or more overlapped with REs of the first one or more ZP CSI-RS resource sets ([0276], N codewords overlaps with any resource element RE in the first resource set; overlapped RE) at least based on a DCI field included in the DCI (Table 1 and [0255], an indication field in the DCI to indicate the enabled ZP CSI-RS resource set; different ZP CSI-RS resource sets are dynamically selected by indicating different state values of the indication field. As shown in Table 1).
LIU does not specifically teach
in a case that the DCI format is DCI format 1_0, determine one or more REs of the PDSCH overlapped with REs of the first one or more ZP CSI-RS resource sets or REs of the second one or more ZP CSI-RS resource sets as available REs for the PDSCH;
in a case that the DCI format is DCI format 1_1, determine one or more REs of the PDSCH overlapped with REs of the second one or more ZP CSI-RS resource sets as available REs for the PDSCH, and determine whether one or more REs of the PDSCH overlapped with REs of the first one or more ZP CSI-RS resource sets as available REs for the PDSCH or as unavailable REs for the PDSCH at least based on a DCI field included in the DCI format 1_1; and
in a case that the DCI format is DCI format 1_2, determine one or more REs of the PDSCH overlapped with REs of the first one or more ZP CSI-RS resource sets as available REs for the PDSCH, and determine whether one or more REs of the PDSCH overlapped with REs of the second one or more ZP CSI-RS resource sets as available REs for the PDSCH or as un available REs for the PDSCH at least based on a DCI field included in the DCI format 1_2.
However, Qualcomm teaches (Title, CR on 38.214 PDSCH resource mapping)
receive first one or more zero power channel state information reference signal (ZP CSI-RS) resource sets and second one or more ZP CSI-RS resource sets (Pg.4: section 5.1.4.2, UE is configured with one or more ZP CSI-RS resource set configuration(s)) and a DCI format scheduling a physical downlink shared channel (PDSCH) (Pg.4: section 5.1.4.2, PDSCH scheduled by PDCCH with DCI format); and
in a case that the DCI format is DCI format 1_0, determine one or more REs of the PDSCH overlapped with REs of the first one or more ZP CSI-RS resource sets or REs of the second one or more ZP CSI-RS resource sets as available REs for the PDSCH (Pg.5: section 5.1.4.2, When receiving PDSCH scheduled by DCI format 1_0 or PDSCHs with SPS activated by DCI format 1_0, the REs corresponding to configured resources in aperiodic-ZP-CSI-RS-ResourceSetsToAddModList are available for PDSCH. Here, the REs of the ZP CSI-RS are available for the PDSCH, i.e. one or more REs of the PDSCH overlapped with REs of the first or the second ZP CSI-RS resource sets);
in a case that the DCI format is DCI format 1_1, determine one or more REs of the PDSCH overlapped with REs of the second one or more ZP CSI-RS resource sets as available REs for the PDSCH (Pg.5: section 5.1.4.2, Each non-zero codepoint of ZP CSI-RS trigger in DCI format 1_1 triggers one aperiodic ZP-CSI-RS-ResourceSet in the list aperiodic-ZP-CSI-RS-ResourceSetsToAddModList by indicating the aperiodic ZP CSI-RS resource set ID), and determine whether one or more REs of the PDSCH overlapped with REs of the first one or more ZP CSI-RS resource sets as available REs for the PDSCH or as unavailable REs for the PDSCH at least based on a DCI field included in the DCI format 1_1 (Pg.3: section 5.1.4.1, When receiving PDSCHs with SPS activated by a DCI format 1_1, the REs corresponding to configured resources in rateMatchPatternGroup1 or rateMatchPatternGroup2 are not available for the PDSCHs with SPS if a corresponding bit of the Rate matching indicator field of the DCI format 1_1 activating the PDSCHs with SPS is equal to 1; Pg.4: section 5.1.4.2, The REs indicated by p-ZP-CSI-RS-ResourceSet are declared as not available for PDSCH. The REs indicated by sp-ZP-CSI-RS-ResourceSetsToAddModList and aperiodic-ZP-CSI-RS-ResourceSetsToAddModList are declared as not available for PDSCH when their triggering and activation are applied, respectively. Here, based on DCI format 1_1, some ZP-CSI-RS-ResourceSets are not available for the PDSCH); and
in a case that the DCI format is DCI format 1_2, determine one or more REs of the PDSCH overlapped with REs of the first one or more ZP CSI-RS resource sets as available REs for the PDSCH, and determine whether one or more REs of the PDSCH overlapped with REs of the second one or more ZP CSI-RS resource sets as available REs for the PDSCH or as un available REs for the PDSCH at least based on a DCI field included in the DCI format 1_2 (Pg.4: section 5.1.4.2, The procedures for PDSCH scheduled by PDCCH with DCI format 1_1 described in this clause equally apply to PDSCH scheduled by PDCCH with DCI format 1_2, by applying the parameters of aperiodic-ZP-CSI-RS-ResourceSetsToAddModList-ForDCIFormat1_2 instead of aperiodic-ZP-CSI-RS-ResourceSetsToAddModList. Here, same citation for DCI format 1_1 and 1_2. Here, based on DCI format 1_2, some ZP-CSI-RS-ResourceSets are not available for the PDSCH).
Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to have modified LIU as mentioned above and further incorporate the teaching of Qualcomm. The motivation for doing so would have been to provide method and apparatus for performing PDSCH resource mapping for improved decoding of PDSCH (Qualcomm, Title and Pg.2).
Regarding claim 4, LIU teaches (Title, RESOURCE CONFIGURATION METHOD AND COMMUNICATIONS APPARATUS) a base station (Fig.11 and [0418], communications apparatus 1100 is a network device), comprising:
transmission circuitry (Fig.11and [0419], communications module 1102) configured to transmit ([0421], The communications module 1102 is configured to perform step 402, step 404 shown in FIG. 4), to a user equipment, a first radio resource control (RRC) parameter indicating first one or more zero power channel state information reference signal (ZP CSI-RS) resource sets and a second RRC parameter indicating second one or more ZP CSI-RS resource sets (Fig.4, step 402 and step 403. [0251], base station A sends a plurality of ZP CSI-RS resource sets and configuration information of a ZP CSI-RS resource in each ZP CSI-RS resource set to the terminal device A through higher layer signaling, e.g., through radio resource control (RRC) signaling; [0301], the first resource set is the ZP CSI-RS resource set 1 and the second resource set is the ZP CSI-RS resource set 2.

determine one or more overlapped with REs of the second one or more ZP CSI-RS resource sets ([0276], N codewords overlaps with any RE in the second resource set; overlapped RE), at least based on a DCI field in the DCI (Table 1 and [0255], an indication field in the DCI to indicate the enabled ZP CSI-RS resource set; different ZP CSI-RS resource sets are dynamically selected by indicating different state values of the indication field. As shown in Table 1); and
determine one or more overlapped with REs of the first one or more ZP CSI-RS resource sets ([0276], N codewords overlaps with any resource element RE in the first resource set; overlapped RE) at least based on a DCI field included in the DCI (Table 1 and [0255], an indication field in the DCI to indicate the enabled ZP CSI-RS resource set; different ZP CSI-RS resource sets are dynamically selected by indicating different state values of the indication field. As shown in Table 1).
LIU does not specifically teach

The motivation for doing so would have been to provide method and apparatus for performing PDSCH resource mapping for improved decoding of PDSCH (Qualcomm, Title and Pg.2).
Regarding claims 2 and 5, combination of LIU and Qualcomm teaches all the features with respect to claims 1 and 4, respectively as outlined above.
LIU further teaches
the DCI field triggers a ZP CSI-RS resource set from the first one or more ZP CSI-RS resource sets (Table 1 and [0255], an indication field in the DCI to indicate the enabled ZP CSI-RS resource set; [0243], technical terms “enable” and “trigger” is used interchangeably; [0261] and [0263], DCI is used to indicate a ZP CSI-RS resource set), determine overlapped with REs of the ZP CSI-RS resource set ([0276], overlapped RE).

Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to have modified combination of LIU and Qualcomm as mentioned in claims 1 and 4 and further incorporate the teaching of Qualcomm. The motivation for doing so would have been to provide method and apparatus for performing PDSCH resource mapping for improved decoding of PDSCH (Qualcomm, Title and Pg.2).
Regarding claims 3 and 6, combination of LIU and Qualcomm teaches all the features with respect to claims 1 and 4, respectively as outlined above.
LIU further teaches
the DCI field triggers a ZP CSI-RS resource set from the second one or more ZP CSI-RS resource sets (Table 1 and [0255], an indication field in the DCI to indicate the enabled ZP CSI-RS resource set; [0243], technical terms “enable” and “trigger” is used interchangeably; [0261] and [0263], DCI is used to indicate a ZP CSI-RS resource set), determine overlapped with REs of the ZP CSI-RS resource set ([0276], overlapped RE).

The motivation for doing so would have been to provide method and apparatus for performing PDSCH resource mapping for improved decoding of PDSCH (Qualcomm, Title and Pg.2).
Regarding claim 7, LIU teaches a communication method (Title, RESOURCE CONFIGURATION METHOD AND COMMUNICATIONS APPARATUS) of a user equipment (UE) (Fig.4 and [0273], a flowchart of a resource configuration method; the method is performed by a terminal device), the communication method comprising:
receiving, from a base station, a first radio resource control (RRC) parameter indicating first one or more zero power channel state information reference signal (ZP CSI-RS) resource sets and a second RRC parameter indicating second one or more ZP CSI-RS resource sets (Fig.4, step 402 and step 403.

receiving a DCI format (Fig.4, step 404. [0302], terminal device A receives the DCI) scheduling a physical downlink shared channel (PDSCH) ([0346], (PDSCH resource allocated to the terminal device A is indicated through the DCI); and

determining one or more overlapped with REs of the second one or more ZP CSI-RS resource sets ([0276], N codewords overlaps with any RE in the second resource set; overlapped RE), at least based on a DCI field in the DCI (Table 1 and [0255], an indication field in the DCI to indicate the enabled ZP CSI-RS resource set; different ZP CSI-RS resource sets are dynamically selected by indicating different state values of the indication field. As shown in Table 1); and

receiving first one or more zero power channel state information reference signal (ZP CSI-RS) resource sets and second one or more ZP CSI-RS resource sets (Pg.4: section 5.1.4.2, UE is configured with one or more ZP CSI-RS resource set configuration(s));
receiving a DCI format scheduling a physical downlink shared channel (PDSCH) (Pg.4: section 5.1.4.2, PDSCH scheduled by PDCCH with DCI format); and
in a case that the DCI format is DCI format 1_0, determine one or more REs of the PDSCH overlapped with REs of the first one or more ZP CSI-RS resource sets or REs of the second one or more ZP CSI-RS resource sets as available REs for the PDSCH (Pg.5: section 5.1.4.2, When receiving PDSCH scheduled by DCI format 1_0 or PDSCHs with SPS activated by DCI format 1_0, the REs corresponding to configured resources in aperiodic-ZP-CSI-RS-ResourceSetsToAddModList are available for PDSCH. Here, the REs of the ZP CSI-RS are available for the PDSCH, i.e. one or more REs of the PDSCH overlapped with REs of the first or the second ZP CSI-RS resource sets);
in a case that the DCI format is DCI format 1_1, determine one or more REs of the PDSCH overlapped with REs of the second one or more ZP CSI-RS resource sets as available REs for the PDSCH (Pg.5: section 5.1.4.2, Each non-zero codepoint of ZP CSI-RS trigger in DCI format 1_1 triggers one aperiodic ZP-CSI-RS-ResourceSet in the list aperiodic-ZP-CSI-RS-ResourceSetsToAddModList by indicating the aperiodic ZP CSI-RS resource set ID), and determine whether one or more REs of the PDSCH overlapped with REs of the first one or more ZP CSI-RS resource sets as available REs for the PDSCH or as unavailable REs for the PDSCH at least based on a DCI field included in the DCI format 1_1 (Pg.3: section 5.1.4.1, When receiving PDSCHs with SPS activated by a DCI format 1_1, the REs corresponding to configured resources in rateMatchPatternGroup1 or rateMatchPatternGroup2 are not available for the PDSCHs with SPS if a corresponding bit of the Rate matching indicator field of the DCI format 1_1 activating the PDSCHs with SPS is equal to 1; Pg.4: section 5.1.4.2, The REs indicated by p-ZP-CSI-RS-ResourceSet are declared as not available for PDSCH. The REs indicated by sp-ZP-CSI-RS-ResourceSetsToAddModList and aperiodic-ZP-CSI-RS-ResourceSetsToAddModList are declared as not available for PDSCH when their triggering and activation are applied, respectively. Here, based on DCI format 1_1, some ZP-CSI-RS-ResourceSets are not available for the PDSCH); and
in a case that the DCI format is DCI format 1_2, determine one or more REs of the PDSCH overlapped with REs of the first one or more ZP CSI-RS resource sets as available REs for the PDSCH, and determine whether one or more REs of the PDSCH overlapped with REs of the second one or more ZP CSI-RS resource sets as available REs for the PDSCH or as un available REs for the PDSCH at least based on a DCI field included in the DCI format 1_2 (Pg.4: section 5.1.4.2, The procedures for PDSCH scheduled by PDCCH with DCI format 1_1 described in this clause equally apply to PDSCH scheduled by PDCCH with DCI format 1_2, by applying the parameters of aperiodic-ZP-CSI-RS-ResourceSetsToAddModList-ForDCIFormat1_2 instead of aperiodic-ZP-CSI-RS-ResourceSetsToAddModList. Here, same citation for DCI format 1_1 and 1_2. Here, based on DCI format 1_2, some ZP-CSI-RS-ResourceSets are not available for the PDSCH).
Therefore, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to have modified LIU as mentioned above and further incorporate the teaching of Qualcomm. The motivation for doing so would have been to provide method and apparatus for performing PDSCH resource mapping for improved decoding of PDSCH (Qualcomm, Title and Pg.2).
Conclusion
The prior arts made of record and not relied upon are considered pertinent to applicant's disclosure.
BIN SEDIQ AKRAM et al. (Pub. No. WO 2019/193520 A1) – “POWER BOOSTING AROUND ZERO-POWER REFERENCE SIGNALS” discloses a method performed by a wireless device comprises obtaining a power boosting configuration(s) comprising a power boosting configuration(s) for a Zero Power (ZP) Channel State Information Reference Signal (CSI-RS) resource(s), a power boosting configuration(s) for a ZP CSI-RS resource set(s), a power boosting configuration(s) for a Channel State Information Interference Measurement (CSI-IM) resource(s), and/or a power boosting configuration(s) for a CSI-IM resource set(s). The method further comprises, for an Orthogonal Frequency Division Multiplexing (OFDM) symbol within a downlink slot in which the wireless device is scheduled with a downlink channel or signal, determining a power boost value for the downlink channel or signal within the OFDM symbol based on the applicable power boosting configuration(s). The method further comprises decoding the downlink channel or signal in the OFDM symbol based on the power boost.
