DETAILED ACTION
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 .
Continued Examination Under 37 CFR 1.114
A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 3/13/2026 has been entered.
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.
Claim(s) 1, 2, 6, 8, 11, 14, 15, 17, 18, 22-32 is/are rejected under 35 U.S.C. 103 as being unpatentable over Zhou US 2022/0022054 in view of Wang et al. ‘Wang” US 2019/0230730 and further in view of Yang et al. “Yang” US 2021/0399858.
Regarding claims 1 and 14, Zhou teaches a method and terminal device configured to:
Acquire channel-occupation spatial information according to a TCI state
configured by a network device, wherein the TCI state is activated through a MAC and configured to indicate a direction in which the terminal device performs LBT before UL transmission (the UE determines a subband occupied by a DL channel using received DL information regarding resources occupied by the base station in each spatial direction. Further the UE obtains channel occupancy information; Paragraphs 112 and 117-118. Paragraphs 29 and 54 further disclose LBT with respect to a particular direction. The signaling, including TCI, is activated by MAC; Paragraph 47. Thus one can see the information received from the base station which involves spatial/directions is used in determining the LBT direction).
determining, according to the channel-occupation spatial information, channel-
sensing spatial information of the terminal device (Paragraphs 112 and 118 teach a UE receiving information with respect to available resources (spatial direction). Further, Paragraph 43 and Table 1 teach the use of MCOT as well. This is the period of time in which a UE can sense a channel and occupy if it’s available (equivalent to applications MCOT for channel sensing in published paragraph 91 of the instant application) Further paragraphs 33-35 and 54 teach the well-known technique of LBT process which is a UE sensing a channel to be busy or not and occupying it if it’s not sensed to be busy. Thus one can see the terminal determines channel sensing spatial information).
Zhou does not expressly disclose the TCI is activated through MAC-CE; however, Wang teaches the UE receiving a MAC CE activation command for a TCI state; Paragraph 32.
Thus it would have been obvious to one of ordinary skill in the art at the time of the effective filing to modify the teachings of Zhou to include MAC-CE for TCI state activation as taught by Wang.
One would be motivated to make the modification such that the UE can properly activate the TCI state and stop monitoring PDCCH candidates as taught by Wang; Paragraph 32.
While Zhou teaches informing the UE of the UL beam direction (Paragraph 53), the prior art does not expressly disclose indicating an uplink direction in which the terminal performs LBT before UL transmission; however, Yang teaches TCI fields are included in DCI; Paragraph 54. Further, when a UL channel transmission is scheduled with respect to LBTs, this information is sent, via DCI, to the UE; Paragraphs 224-225. Thus one can see the LBT direction, in the uplink, is indicated to the UE as claimed.
Thus it would have been obvious to one of ordinary skill in the art at the time of the effective filing to modify the teachings of the prior to include indicating an UL direction for LBT as taught by Yang.
One would be motivated to make the modification such that the UE can be notified of which UL LBTs are identified to the UE to perform for UL channel transmissions as taught by Yang; Paragraphs 224-225.
Regarding claims 2 and 15, Zhou teaches acquire channel-occupation spatial information from a DCI carrying UL grant (the UE determines a subband occupied by a DL channel using received DL information regarding resources occupied by the base station in each spatial direction. Further the UE obtains, from the DCI format 2_0 (grant information for scheduling), channel occupancy information; Paragraphs 112 and 117-118) or
acquiring the channel-occupation spatial information comprises acquiring the information through DL (the UE determines a subband occupied by a DL channel using received DL (i.e. information acquired through the DL) information regarding resources occupied by the base station in each spatial direction. Further the UE obtains, from the DCI, channel occupancy information; Paragraphs 112-118. Further paragraphs 33-35 and 54 teach the well-known technique of LBT process which can also read on the DCI with a grant of access).
Regarding claims 6 and 17, Zhou teaches performing, by the terminal device, channel sensing according to LBT directional information of the terminal device, and when a result of the channel sensing indicates a free channel, using the free channel for UL transmissions (Paragraphs 112 and 118 teach a UE receiving information with respect to available resources (spatial direction). Further, Paragraph 43 and Table 1 teach the use of MCOT as well. This is the period of time in which a UE can sense a channel and occupy if it’s available (equivalent to applications MCOT for channel sensing in published paragraph 91 of the instant application) Further paragraphs 33-35 and 54 teach the well-known technique of LBT process which is a UE sensing a channel to be busy or not and occupying it if it’s not sensed to be busy. Thus one can see the terminal performs LBT based on the determined LBT directional information and using the free channel).
While Zhou teaches the use of TCI states and acquiring channel-occupation spatial information as taught above; however, Zhou does not disclose the use of MSG2 which carries the spatial information and MSG3 for transmission of the UE on a free channel. Wang teaches spatial information related to CSI-RS and SS/PBCH can be sent to the UE using MSG2. Further, during failure recovery the UE can identify a candidate beam (i.e. sense a beam) and then use a MSG3 to transmit; Paragraphs 22-23).
Thus it would have been obvious to one of ordinary skill in the art at the time of the effective filing to modify the teachings of Zhou to include MSG2 and MSG3 for sensing and transmitting as taught by Wang.
One would be motivated to make the modification such that the UE can properly detect a candidate beam to use for transmission as taught by Wang; Paragraphs 22-23.
Regarding claims 8 and 18, Zhou teaches a method and network device, comprising a processor and a memory, wherein the memory is configured to store a computer program, and the processor, through invoking and running the computer program stored in the memory, is configured to:
Determining channel-occupation spatial information and indicating the channel-
occupation spatial information through a TCI state configured by a network device, wherein the TCI state is activated through a MAC and configured to indicate a direction in which the terminal device performs LBT before UL transmission (the UE determines a subband occupied by a DL channel using received DL information regarding resources occupied by the base station in each spatial direction. Further the UE obtains channel occupancy information; Paragraphs 112 and 117-118. Paragraphs 29 and 54 further disclose LBT with respect to a particular direction. The signaling, including TCI, is activated by MAC; Paragraph 47. Thus one can see the information received from the base station which involves spatial/directions is used in determining the LBT direction.
Zhou does not expressly disclose the TCI is activated through MAC-CE; however, Wang teaches the UE receiving a MAC CE activation command for a TCI state; Paragraph 32.

Thus one can see the LBT direction, in the uplink, is indicated to the UE as claimed.
Thus it would have been obvious to one of ordinary skill in the art at the time of the effective filing to modify the teachings of the prior to include indicating an UL direction for LBT as taught by Yang.
One would be motivated to make the modification such that the UE can be notified of which UL LBTs are identified to the UE to perform for UL channel transmissions as taught by Yang; Paragraphs 224-225.
Regarding claims 11 and 22, Zhou teaches the use of TCI states and acquiring channel-occupation spatial information as taught above; however, Zhou does not disclose the use of MSG2 which carries the spatial information and MSG3 for transmission of the UE on a free channel.

Further, during failure recovery the UE can identify a candidate beam (i.e. sense a beam) and then use a MSG3 to transmit; Paragraphs 22-23).
Thus it would have been obvious to one of ordinary skill in the art at the time of the effective filing to modify the teachings of Zhou to include MSG2 and MSG3 for sensing and transmitting as taught by Wang.
One would be motivated to make the modification such that the UE can properly detect a candidate beam to use for transmission as taught by Wang; Paragraphs 22-23.
Regarding claim 23, Zhou teaches the DCI is format 2_0 (Paragraphs 112 and 117 teaches DCI format 2_0. The paragraphs state no additional DCI format 2_0 is needed which implies there is at least one DCI format 2_0).
Zhou teaches the use of TCI states (Paragraph 47), sounding reference signals (paragraph 53) and acquiring channel-occupation spatial information as taught above; however, Zhou does not expressly disclose the spatial information includes TCI or SS/PBCH. Wang teaches spatial information related to CSI-RS and SS/PBCH can be sent to the UE using MSG2. Further, during failure recovery the UE can identify a candidate beam (i.e. sense a beam) and then use a MSG3 to transmit; Paragraphs 22-23).
