Claim Rejections - 35 USC § 103
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.
Claims 1-13, 17-22, and 25 are rejected under 35 U.S.C. 103 as being unpatentable over Kim et al. (US 2022/0217694 A1), hereafter referred Kim, in view of Moon et al. (US 2020/0367242 A1), hereafter referred Moon. Kim was cited by applicant’s IDS filed 26 June 2024.
Regarding claim 1, Kim teaches an operating method of a terminal to communicate with a base station, the operating method comprising:
detecting at least one overlapped third control channel element (CCE) in a plurality of first CCEs included in first search spaces corresponding to a first physical downlink control channel (PDCCH) received from a first transmission and reception point (TRP) of the base station, and in a plurality of second CCEs included in second search spaces corresponding to a second PDCCH received from the first TRP and a second TRP of the base station (Kim, [0326]-[0327]; when collision/overlapping occurs between CORESETs configured different Type-D RSs as QCL sources, a monitoring CORESET may be selected among a CORESET in which MTRP PDCCH repeated transmission is configured, where a method in which two TRPs repeatedly transmit a PDCCH by FDM/TDM (ie. SS sets associated with each of the two CORESETs are configured to be linked for PDCCH repeated transmission and each PDCCH candidate of the two linked SS sets is TDMed or FDMed and used for the same DCI repeated transmission and a method in which two TRPs transmit a PDCCH by SFN (ie. two TCI states are configured/activated in one CORESET and a UE performs channel estimation of a PDCCH DMRS using two QCL RSs corresponding to the two TCI states through a PDCCH of an SS set associated with the CORESET);
determining, based on the at least one overlapped third CCE, object CCEs from the plurality of first CCEs and the plurality of second CCEs (Kim, [0326]-[0331]; the CORESET in which TDM/FDM PDCCH repeated transmission is configured has a priority and can be compared with the priority of the CORESET in which SFN PDCCH transmission is configured).
While Kim teaches performing channel estimation (Kim, [0326]-[0331] and [0412]; a UE performs channel estimation where a processor may control to store channel information in a memory), Kim does not expressly teach allocating a first memory based on the object CCEs; and
performing channel estimation of the object CCEs by using the first memory.
However, Moon teaches allocating a first memory based on the object CCEs (Moon, [0218]-[0224]; the first control resource set may be a terminal-specific search space based on narrowband DMRS and the second control resource set may be a common search space based on wideband DMRS, where when the CCE #0 is allocated to the second control resource set, the REGs constituting the CCE #0 of the second control resource set are distributed in REG units in the frequency domain so that the REGs constituting the CCE #0 of the second control resource set may be overlapped with the 6 CCEs of the first control resource set); and
performing channel estimation of the object CCEs by using the first memory (Moon, [0157]; the terminal may estimate a channel using all the DMRSs received in the REG bundle).
It would have been obvious to a person of ordinary skill in the art at the time of the effective filing date of the invention to create the invention of Kim to include the above recited limitations as taught by Moon in order to improve the channel estimation performance (Moon, [0157]).
Regarding claim 17, Kim teaches an operating method of a terminal, the operating method comprising:
detecting an overlapped third control channel element (CCE) in a plurality of first CCEs included in common search spaces and based on a single transmission configuration indicator (TCI) state, and in a plurality of second CCEs included in user specific search spaces and based on multiple TCI states (Kim, [0326]-[0327]; when collision/overlapping occurs between CORESETs configured different Type-D RSs as QCL sources, a monitoring CORESET may be selected among a CORESET in which MTRP PDCCH repeated transmission is configured, where a method in which two TRPs repeatedly transmit a PDCCH by FDM/TDM (ie. SS sets associated with each of the two CORESETs are configured to be linked for PDCCH repeated transmission and each PDCCH candidate of the two linked SS sets is TDMed or FDMed and used for the same DCI repeated transmission and a method in which two TRPs transmit a PDCCH by SFN (ie. two TCI states are configured/activated in one CORESET and a UE performs channel estimation of a PDCCH DMRS using two QCL RSs corresponding to the two TCI states through a PDCCH of an SS set associated with the CORESET);
counting a number of non-overlapped CCEs based on the overlapped third CCE (Kim, [0245]-[0250]; determining the number of non-overlapped CCEs is defined according to the UE counting the number of CCEs when the PDCCH is transmitted repeatedly or dividedly).
Kim does not expressly teach allocating a first memory based on the number of non-overlapped CCEs; and
performing, using the first memory, channel estimation of the object CCEs by using the first memory.
However, Moon teaches allocating a first memory based on the number of non-overlapped CCEs (Moon, [0218]-[0224]; the first control resource set may be a terminal-specific search space based on narrowband DMRS and the second control resource set may be a common search space based on wideband DMRS, where when the CCE #0 is allocated to the second control resource set, the REGs constituting the CCE #0 of the second control resource set are distributed in REG units in the frequency domain so that the REGs constituting the CCE #0 of the second control resource set may be overlapped with the 6 CCEs of the first control resource set, while the PDCCH may not be allocated to the 6 CCEs of the first control resource set); and
performing, using the first memory, channel estimation of the object CCEs by using the first memory (Moon, [0157]; the terminal may estimate a channel using all the DMRSs received in the REG bundle).
It would have been obvious to a person of ordinary skill in the art at the time of the effective filing date of the invention to create the invention of Kim to include the above recited limitations as taught by Moon in order to improve the channel estimation performance (Moon, [0157]).
Regarding claim 25, Kim teaches an operating method of a terminal, the operating method comprising:

SS sets associated with each of the two CORESETs are configured to be linked for PDCCH repeated transmission and each PDCCH candidate of the two linked SS sets is TDMed or FDMed and used for the same DCI repeated transmission and a method in which two TRPs transmit a PDCCH by SFN (ie. two TCI states are configured/activated in one CORESET and a UE performs channel estimation of a PDCCH DMRS using two QCL RSs corresponding to the two TCI states through a PDCCH of an SS set associated with the CORESET);
identifying whether a first memory allocated to channel estimation of the plurality of first CCEs and the plurality of second CCEs is sufficient, based on a number of non-overlapped CCEs in the plurality of first CCEs and the plurality of second CCEs (Kim, [0244]-[0253]; a UE may count PDCCH BDs and the number of CCE channel estimations for a specific time unit and determine whether a PDCCH is overbooked by comparing it with the limit of the UE).
While Kim teaches performing a channel estimation based on the multiple TCI states (Kim, [0326]-[0327]; a UE performs channel estimation of a PDCCH DMRS using two QCL RSs corresponding to the two TCI states through a PDCCH of an SS set associated with the CORESET), Kim does not expressly teach allocating a second memory based on identifying that the first memory is not sufficient; and
performing, based on a result of the identifying, a channel estimation of the overlapped third CCE based on the common and user specific search spaces.
However, Moon teaches allocating a second memory based on identifying that the first memory is not sufficient (Moon, [0218]-[0224]; the first control resource set may be a terminal-specific search space based on narrowband DMRS and the second control resource set may be a common search space based on wideband DMRS, where when the CCE #0 is allocated to the second control resource set, the REGs constituting the CCE #0 of the second control resource set are distributed in REG units in the frequency domain so that the REGs constituting the CCE #0 of the second control resource set may be overlapped with the 6 CCEs of the first control resource set, while the PDCCH may not be allocated to the 6 CCEs of the first control resource set); and
performing, based on a result of the identifying, a second channel estimation of the overlapped third CCE based on the common and user specific search spaces (Moon, [0157] and [0218]-[0224]; the terminal may estimate a channel using all the DMRSs received in the REG bundle, where a terminal-specific search space is associated with the narrowband DMRS and a common search space is associated with the wideband DMRS).

Kim does not expressly teach performing the channel estimation of the selected overlapped third CCE.
However, Moon teaches performing the channel estimation of the selected overlapped third CCE (Moon, [0157]; the terminal may estimate a channel using all the DMRSs received in the REG bundle).
It would have been obvious to a person of ordinary skill in the art at the time of the effective filing date of the invention to create the invention of Kim to include the above recited limitations as taught by Moon in order to improve the channel estimation performance (Moon, [0157]).
Regarding claim 20, Kim in view of Moon teaches the operating method of claim 19 above. Further, Kim teaches wherein the selecting of the overlapped third CCE comprises:

storing a first result of the first channel estimation and a second result of the second channel estimation in the channel estimation memory (Kim, [0326]-[0331] and [0412]; a UE performs channel estimation where a processor may control to store channel information in a memory).
While Kim teaches performing channel estimation based on the single TCI state or the multiple TCI states (Kim, [0248]; when a PDCCH is SFN transmitted (using a plurality of TCI states), the UE performs channel estimation for each of the PDCCH received from TRP 1 (with the first TCI state) and the PDCCH received from TRP 2 (with the second TCI state)), Kim does not expressly teach performing a first channel estimation of the overlapped third CCE based on the common search space and a second channel estimation of the overlapped third CCE based on the user specific search space.
However, Moon teaches performing a first channel estimation of the overlapped third CCE based on the common search space and a second channel estimation of the overlapped third CCE based on the user specific search space (Moon, [0157] and [0218]-[0224]; the terminal may estimate a channel using all the DMRSs received in the REG bundle, where a terminal-specific search space is associated with the narrowband DMRS and a common search space is associated with the wideband DMRS).
It would have been obvious to a person of ordinary skill in the art at the time of the effective filing date of the invention to create the invention of Kim to include the above recited limitations as taught by Moon in order to improve the channel estimation performance (Moon, [0157]).
