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 . Claim Rejections - 35 USC § 102 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 16-19 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Huang et al (US 20230131045) (hereinafter Huang). Regarding claim 16, Huang discloses a terminal (e.g., UE 115) comprising: a receiver that receives higher layer signaling that configures whether or not to report a parameter regarding a type II port selection codebook structure for Channel State Information (CSI) (see Huang, p. [0070], e.g., The BS 105 may transmit wideband CSI-RSs with the wideband beamforming ports and additionally a CSI report configuration message to the UE 115, where the CSI report configuration message indicates that the CSI report is based on port selection with these CSI-RS ports); a processor that determines, based on the higher layer signaling, whether or not to report the parameter (see Huang, p. [0070], e.g., The UE 115 may receive the wideband CSI-RSs with the wideband beamforming ports and the CSI report configuration message from the BS 105, select a number of the received wideband CSI-RS ports, and combine them with a respective coefficient for each port, and p. [0075], e.g., The UE 115 may report CSI-RS ports i0, . . . ikO/2-1 and port coefficients c0, . . . ck0-1or a subset of port coefficients c0, ck0-1, where the unreported port coefficients are set to 0); and a transmitter that, when the parameter is reported, reports a bitmap identifying which coefficients within a matrix regarding the type II port selection codebook structure are reported, as part of a Precoding Matrix Indicator (PMI) (see Huang, p. [0070], e.g., The UE 115 may then report the port selection result and the respective coefficients in the CSI report to the BS 105, and p. [0080], [0111-0114]). Regarding claim 17, Huang discloses a radio communication method for a terminal (e.g., UE 115), comprising: receiving higher layer signaling that configures whether or not to report a parameter regarding a type II port selection codebook structure for Channel State Information (CSI) (see Huang, p. [0070], e.g., The BS 105 may transmit wideband CSI-RSs with the wideband beamforming ports and additionally a CSI report configuration message to the UE 115, where the CSI report configuration message indicates that the CSI report is based on port selection with these CSI-RS ports); determining, based on the higher layer signaling, whether or not to report the parameter (see Huang, p. [0070], e.g., The UE 115 may receive the wideband CSI-RSs with the wideband beamforming ports and the CSI report configuration message from the BS 105, select a number of the received wideband CSI-RS ports, and combine them with a respective coefficient for each port, and p. [0075], e.g., The UE 115 may report CSI-RS ports i0, . . . ikO/2-1 and port coefficients c0, . . . ck0-1or a subset of port coefficients c0, ck0-1, where the unreported port coefficients are set to 0); and when the parameter is reported, reporting a bitmap identifying which coefficients within a matrix regarding the type II port selection codebook structure are reported, as part of a Precoding Matrix Indicator (PMI) (see Huang, p. [0070], e.g., The UE 115 may then report the port selection result and the respective coefficients in the CSI report to the BS 105, and p. [0080], [0111-0114]). Regarding claim 18, Huang discloses a base station (e.g., BS 105) comprising: a transmitter that transmits higher layer signaling that configures whether or not to report a parameter regarding a type II port selection codebook structure for Channel State Information (CSI) (see Huang, p. [0070], e.g., The BS 105 may transmit wideband CSI-RSs with the wideband beamforming ports and additionally a CSI report configuration message to the UE 115, where the CSI report configuration message indicates that the CSI report is based on port selection with these CSI-RS ports); a processor that configures, by the higher layer signaling, whether or not to report the parameter; and a receiver that, when the parameter is reported, receives a bitmap, reported as part of a Precoding Matrix Indicator (PMI) (see Huang, p. [0070], e.g., The UE 115 may receive the wideband CSI-RSs with the wideband beamforming ports and the CSI report configuration message from the BS 105, select a number of the received wideband CSI-RS ports, and combine them with a respective coefficient for each port, and p. [0075], e.g., The UE 115 may report CSI-RS ports i0, . . . ikO/2-1 and port coefficients c0, . . . ck0-1or a subset of port coefficients c0, ck0-1, where the unreported port coefficients are set to 0), identifying which coefficients within a matrix regarding the type II port selection codebook structure are reported (see Huang, p. [0070], e.g., The UE 115 may then report the port selection result and the respective coefficients in the CSI report to the BS 105, and p. [0080], [0111-0114]). Regarding claim 19, Huang discloses a system comprises a terminal and a base station (see Huang, Fig. 1), wherein: the terminal comprising: a first receiver that receives higher layer signaling that configures whether or not to report a parameter regarding a type II port selection codebook structure for Channel State Information (CSI) (see Huang, p. [0070], e.g., The BS 105 may transmit wideband CSI-RSs with the wideband beamforming ports and additionally a CSI report configuration message to the UE 115, where the CSI report configuration message indicates that the CSI report is based on port selection with these CSI-RS ports); a first processor that determines, based on the higher layer signaling, whether or not to report the parameter; and a first transmitter that, when the parameter is reported, reports a bitmap identifying which coefficients within a matrix regarding the type II port selection codebook structure are reported, as part of a Precoding Matrix Indicator (PMI) (see Huang, p. [0070], e.g., The UE 115 may receive the wideband CSI-RSs with the wideband beamforming ports and the CSI report configuration message from the BS 105, select a number of the received wideband CSI-RS ports, and combine them with a respective coefficient for each port, and p. [0075], e.g., The UE 115 may report CSI-RS ports i0, . . . ikO/2-1 and port coefficients c0, . . . ck0-1or a subset of port coefficients c0, ck0-1, where the unreported port coefficients are set to 0); and the base station comprising: a second transmitter that transmits the higher layer signaling; a second processor configures, by the higher layer signaling, whether or not to report the parameter; and a second receiver that, when the parameter is reported, receives the bitmap (see Huang, p. [0070], e.g., The UE 115 may then report the port selection result and the respective coefficients in the CSI report to the BS 105, and p. [0080], [0111-0114]).
