Office Action

§103
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 (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 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) 1 - 20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Kim, U.S. Patent Publication No. 2014/0050130 in further view of Guo, U.S. Patent Publication No. 2019/0141693. Kim teaches a method of scheduling data transmissions in a wireless communications network. Kim does not teach utilizing a transmission configuration indication (TCI) state. However, Guo teaches utilizing a TCI state. It would have been obvious to one skilled in the art at the time of the filing to modify the teachings of Kim to incorporate the known technique of utilizing a TCI as taught by Guo in order to obtain the predictable result of compliance with standard specifications. The combination teaches: 1. A method performed by a terminal in a communication system, the method comprising: identifying whether a default beam for a cross-scheduled physical downlink shared channel (PDSCH) is allowed or not (when cross carrier scheduling is activated, PDCCH uses a carrier indicator field (CIF), [0135], Kim); in case that the default beam for the cross-scheduled PDSCH is allowed, identifying that a scheduling cell for a physical downlink control channel (PDCCH) and a scheduled cell for a PDSCH are different each other (PDCCH can assign PDSCH resource to one of a plurality of component carriers (CC), [0135], Kim); and in case that a time offset between the PDCCH and the PDSCH is less than a threshold value, receiving, from a base station, the PDSCH based on a transmission configuration indication (TCI) state of lowest identifier (ID) among activated TCI states configured for the PDSCH (TCI state indicated for PDSCH transmission can include TCI=000 (the last TCI state), [0293], Guo). 2. The method of claim 1, wherein downlink control information received on the PDCCH includes a carrier indicator field (CIF) being not set as 0 (CIF is utilized to distinguish a cell transmitting PDSCH, [0197], Kim, the actual value of the CIF is mainly a design choice and not given patentable weight). 3. The method of claim 1, further comprising: in case that the default beam for the cross-scheduled PDSCH is allowed, identifying that a scheduling cell for a PDCCH and a scheduled cell for a PDSCH are the same (PDSCH uses same receive beam of that of the PDCCH that schedules the PDSCH, [0286], Guo); and in case that a time offset between the PDCCH and the PDSCH is less than a threshold value, receiving, from the base station, the PDSCH based on a quasi co-location (QCL) parameter of a control resource set (CORESET) of lowest index among one or more CORESETs corresponding to a monitored search space in latest slot (QCL configuration indicated by the TCI state configured to the lowest-index CORSET, [0293], Guo). 4. The method of claim 1, wherein, in case that the default beam for the cross-scheduled PDSCH is not allowed, a release 15 default beam behavior is applied. (Guo utilizes release 15 standards, [0047]) 5. The method of claim 1, further comprising: transmitting, to the base station, capability information associated with support of the default beam for the cross-scheduled PDSCH (values are chosen based on reported UE capability, [0306], Guo). 6. A method performed by a base station in a communication system, the method comprising: identifying whether a default beam for a cross-scheduled physical downlink shared channel (PDSCH) is allowed or not (when cross carrier scheduling is activated, PDCCH uses a carrier indicator field (CIF), [0135], Kim); in case that the default beam for the cross-scheduled PDSCH is allowed, transmitting, to a terminal, a physical downlink control channel (PDCCH), on a scheduling cell, for scheduling a physical downlink shared channel (PDSCH) on a scheduled cell, wherein the scheduling cell and the scheduled cell are different each other (PDCCH can assign PDSCH resource to one of a plurality of component carriers (CC), [0135, Kim]); and in case that a time offset between the PDCCH and the PDSCH is less than a threshold value, transmitting, to the terminal, the PDSCH based on a quasi co-location parameter associated with a transmission configuration indication (TCI) state of lowest identifier (ID) among activated TCI states configured for the PDSCH (TCI state indicated for PDSCH transmission can include TCI=000 (the last TCI state), [0293], Guo). 7. The method of claim 6, wherein downlink control information transmitted on the PDCCH includes a carrier indicator field (CIF) being not set as 0 (CIF is utilized to distinguish a cell transmitting PDSCH, [0197], Kim, the actual value of the CIF is mainly a design choice and not given patentable weight). 8. The method of claim 6, further comprising: in case that the default beam for the cross-scheduled PDSCH is allowed, transmitting, to the terminal, a PDCCH, on a scheduling cell, for scheduling a PDSCH on a scheduled cell, wherein the scheduling cell and the scheduled cell are the same (PDSCH uses same receive beam of that of the PDCCH that schedules the PDSCH, [0286], Guo); and in case that a time offset between the PDCCH and the PDSCH is less than a threshold value, transmitting, to the terminal, the PDSCH based on a quasi co-location (QCL) parameter of a control resource set (CORESET) of lowest index among one or more CORESETs corresponding to a search space in latest slot (QCL configuration indicated by the TCI state configured to the lowest-index COREET, [0293], Guo). 9. The method of claim 6, wherein, in case that the default beam for the cross-scheduled PDSCH is not allowed, a release 15 default beam behavior is applied (Guo utilizes release 15 standards, [0047]). 10. The method of claim 6, further comprising: receiving, from the terminal, capability information associated with support of the default beam for the cross-scheduled PDSCH (values are chosen based on reported UE capability, [0306], Guo). 11. A terminal in a communication system, the terminal comprising: a transceiver (see Fig. 2, Guo); and a controller coupled with the transceiver (see Fig. 2, Guo) and configured to: identify whether a default beam for a cross-scheduled physical downlink shared channel (PDSCH) is allowed or not (when cross carrier scheduling is activated, PDCCH uses a carrier indicator field (CIF), [0135], Kim), in case that the default beam for the cross-scheduled PDSCH is allowed, identify that a scheduling cell for a physical downlink control channel (PDCCH) and a scheduled cell for a PDSCH are different each other (PDCCH can assign PDSCH resource to one of a plurality of component carriers (CC), [0135], Kim), and in case that a time offset between the PDCCH and the PDSCH is less than a threshold value, receive, from a base station, the PDSCH based on a transmission configuration indication (TCI) state of lowest identifier (ID) among activated TCI states configured for the PDSCH (TCI state indicated for PDSCH transmission can include TCI=000 (the last TCI state), [0293], Guo). 12. The terminal of claim 11, wherein downlink control information received on the PDCCH includes a carrier indicator field (CIF) being not set as 0 (CIF is utilized to distinguish a cell transmitting PDSCH, [0197], Kim, the actual value of the CIF is mainly a design choice and not given patentable weight). 13. The terminal of claim 11, wherein the controller is further configured to: in case that the default beam for the cross-scheduled PDSCH is allowed, identify that a scheduling cell for a PDCCH and a scheduled cell for a PDSCH are the same (PDSCH uses same receive beam of that of the PDCCH that schedules the PDSCH, [0286], Guo), and in case that a time offset between the PDCCH and the PDSCH is less than a threshold value, receive, from the base station, the PDSCH based on a quasi co-location (QCL) parameter of a control resource set (CORESET) of lowest index among one or more CORESETs corresponding to a monitored search space in latest slot (QCL configuration indicated by the TCI state configured to the lowest-index COREET, [0293], Guo). 14.
