Office Action

§102
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 . DETAILED ACTION This action is responsive to the application filed on 02/23/2024 has a total of 20 claims pending in the application; there are 4 independent claims and 16 dependent claims, all of which are ready for examination by the examiner. 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, 11-21, 31-33 and 36-40 are rejected under 35 U.S.C. 102(a)(2) as being unpatentable by Zhou et al. Publication No. (US 2021/0028843 A1). Regarding claim 1, Zhou teaches a network node configured to communicate with a wireless device, WD (DCI based signaling by a base station may be supported to dynamically indicate a type of CSI reporting (e.g., 3120 or 3140) to a UE [0456] FIG.42), the network node comprising: processing circuitry (processors 321A FIG.3) configured to: determine a plurality of channel state information reference signal, CSI-RS, configurations (indicate to the wireless device a channel state information (CSI) report configuration comprising a plurality of CSI resource configurations for channel measurements [00468-469] FIG.42), the determined plurality of CSI-RS configurations including at least a first CSI-RS configuration and a second CSI-RS configuration (The CSI resource configurations comprise first CSI resource configurations associated with a first transmission reception point (TRP) and second CSI resource configurations associated with at least two second TRPs [0473-475] FIG.39), the first and second CSI-RS configurations comprising different values for at least one parameter (The CSI report configuration may be associated with configuration parameters comprising a CSI report configuration index identifying the CSI report configuration, a carrier indicator, configuration type indicator [different values] [0476-477] FIG.40); determine one of the first CSI-RS configuration and the second CSI- RS configuration usable by the WD to perform a CSI procedure, the one of the first CSI-RS configuration and the second CSI-RS configuration being determined based on at least one condition (the base station sends, to the wireless device, a command comprising a first field triggering [condition] the CSI report configuration and a second field indicating whether the CSI report configuration is associated with the first CSI resource configurations or the second CSI resource configurations [0473-475] FIG.40); and a radio interface (communication interface 320A FIG.3) in communication with the processing circuitry (the communication interface 320A in communication with processor(s) 321A FIG.3), the radio interface being configured to: transmit, to the WD, an indication indicating the determined one of the first CSI-RS configuration and the second CSI-RS configuration (The wireless device may receive a medium access control (MAC) control element (MAC CE) comprising a first field activating the CSI report configuration and a second field indicating whether the CSI report configuration comprises one rank indicator, one precoding matrix indicator and one channel quality indicator or multiple rank indicators, multiple precoding matrix indicators and multiple channel quality indicators [0471-472] FIG.42), the indication being transmitted using at least one of physical communication layer signaling and media access control, MAC, layer signaling (A MAC CE signaling may be used to indicate a CSI reporting type of a CSI report configuration [0460] the base station may dynamically indicate, via physical layer (e.g. a DCI) or MAC layer (e.g. MAC CE) signal, a panel from a base station for CSI reporting [0498] FIG.25). Claims 2-10 (cancelled). Regarding claim 11, related to the same limitation set for hereinabove in claim 1, wherein the difference used is the limitations were presented from a “method in the network node” side and the wordings of the claim were interchanged within the claim itself or were presented as a combination of two or more previously presented limitations. This change does not affect the limitation of the above treated claims. Adding these phrases to the claim and interchanging the wording did not introduce new limitations to this claim. Therefore this claim was rejected for similar reasons as stated above. Regarding claim 12, Zhou teaches the method of Claim 11, wherein the at least one parameter is associated with a CSI-RS resource, each one of the first and second CSI-RS configurations having at least one CSI-RS resource value that is different (The CSI report configuration may be associated with configuration parameters comprising a CSI report configuration index identifying the CSI report configuration, a carrier indicator, configuration type indicator [different values] [0476-477] FIG.40). Regarding claim 13, Zhou teaches the method of Claim 12, wherein the at least one parameter is included in a CSI-RS resource mapping information element and includes at least one of: a port number; and a CSI-RS density (a base station may configure one or more parameters indicating CSI RS resource mapping, for example, time-domain location of one or more CSI-RS resources, a bandwidth of a CSI-RS resource, and/or a periodicity [0263]).

Regarding claim 15, Zhou teaches the method of Claim 11, wherein the at least one parameter is associated with a plurality of CSI-RS resources (a base station may configure one or more parameters indicating CSI RS resource mapping, for example, time-domain location of one or more CSI-RS resources, a bandwidth of a CSI-RS resource, and/or a periodicity [0263]). Regarding claim 16, Zhou teaches the method of Claim 11, wherein the at least one parameter is associated with a plurality of CSI-RS resource sets, each CSI-RS set of the plurality of CSI-RS resource sets corresponding to an index included in the indication (The CSI report configuration may be associated with configuration parameters comprising a CSI report configuration index identifying the CSI report configuration, a carrier indicator, configuration type indicator [different values] [0476-477] FIG.40). Regarding claim 17, Zhou teaches the method of any one of Claim 11, wherein the transmitted indication triggers the WD to at least one of: activate one of the first CSI-RS configuration and the second CSI-RS configuration to perform the CSI procedure; deactivate one of the first CSI-RS configuration and the second CSI-RS configuration to perform the CSI procedure; switch from the first CSI-RS configuration to the second CSI-RS configuration to perform the CSI procedure; and switch from the second CSI-RS configuration to the first CSI-RS configuration to perform the CSI procedure (A radio network may support periodic, aperiodic, and/or semi-persistent transmission of downlink CSI-RS 522. For example, a base station may semi-statistically configure and/or reconfigure a UE with periodic transmission of downlink CSI-RS 522. A configured CSI-RS resources may be activated ad/or deactivated. For semi-persistent transmission, an activation and/or deactivation of CSI-RS resource may be triggered dynamically [0263] FIG.37). Regarding claim 18, Zhou teaches the method of Claim 11, wherein the method further includes: transmitting a CSI-RS based on the determined one of the first CSI-RS configuration and the second CSI-RS configuration; and receiving a CSI report as part of the CSI procedure, the CSI report including at least one measurement based on the determined one of the first CSI-RS configuration and the second CSI-RS configuration (the base station may transmit the information bits with CSI report trigger (e.g., TriggerState) for aperiodic CSI report or semi-persistent CSI report with PUSCH. For example, a wireless device may receive one or more CSI report configurations (e.g., CSI report config in RRC) with a plurality of CSI resource configurations for channel measurement (e.g., CSI Resource Config for Channel #0 and #1).
