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.

In some examples, based on (e.g., in response to) the energy detection threshold (e.g., in response to receiving the COT sharing information indicative of the energy detection threshold), the second UE may determine (e.g., derive) a maximum sidelink transmit power (e.g. the second maximum sidelink transmit power) based on the energy detection threshold).
It would have been obvious to one of ordinary skill in the art at the time of the filing date to combine the disclosure of perform a channel access procedure for a sidelink transmission within the COT resources when COT is initiated by network, as disclosed by Niu in view of Wang, with the disclosure of receiving a sidelink maximum energy detection threshold and setting the energy detection threshold to the sidelink maximum energy detection threshold, as disclosed by Huang. The motivation to combine would have been to support LBT for sidelink transmission (Huang: e.g., ¶ [0002]).
Regarding Claim 16, Niu discloses all the limitations of the wireless communication device of claim 10.
Niu does not expressly disclose wherein the processor and the memory are further configured to: determine the energy detection threshold based on a maximum configured transmit power in sidelink for the wireless communication device and an occupied bandwidth.
Huang discloses wherein the processor and the memory are further configured to: determine the energy detection threshold based on a maximum configured transmit power in sidelink for the wireless communication device and an occupied bandwidth (e.g., ¶ [0661] determine (e.g., derive) a maximum sidelink transmit power… based on the energy detection threshold. In an example, the indicated energy detection threshold is X.sub.Thresh and a bandwidth of the… sidelink transmission).
It would have been obvious to one of ordinary skill in the art at the time of the filing date to combine the disclosure of perform a channel access procedure for a sidelink transmission within the COT resources when COT is initiated by network, as disclosed by Niu in view of Wang, with the disclosure of determining the energy detection threshold based on a maximum configured transmit power in sidelink for the wireless communication device and an occupied bandwidth, as disclosed by Huang. The motivation to combine would have been to support LBT for sidelink transmission (Huang: e.g., ¶ [0002]).
Regarding Claim 21, Niu discloses all the limitations of the method of claim 17.
Niu does not expressly disclose further comprising: receiving at least one of a sidelink maximum energy detection threshold or a sidelink energy detection threshold offset; setting an energy detection threshold to the sidelink maximum energy detection threshold in response to receiving the sidelink maximum energy detection threshold; and adjusting a default energy detection threshold by the sidelink energy detection threshold offset in response to receiving the sidelink energy detection threshold offset without the sidelink maximum energy detection threshold.
Huang discloses further comprising: receiving at least one of a sidelink maximum energy detection threshold or a sidelink energy detection threshold offset; setting an energy detection threshold to the sidelink maximum energy detection threshold in response to receiving the sidelink maximum energy detection threshold (e.g., ¶ [0661] In an example, the first UE indicates the energy threshold as −60 decibels per milliwatt (dBm) (i.e., negative 60 dBm) in the COT sharing information to the second UE (e.g., the first UE may generate the COT sharing information to be indicative of the energy threshold being 60 dBm, and/or the UE may transmit the COT sharing information to the second UE). The second UE may determine (e.g., identify) an energy level with which the first UE accesses the channel. In some examples, the energy threshold is an energy detection threshold. Based on (e.g., in response to) the energy detection threshold (e.g., in response to receiving the COT sharing information indicative of the energy detection threshold), the second UE may determine a sidelink transmission power, for sidelink transmission, that is under −60 dbm (e.g., the energy detection threshold) (e.g., the second UE may determine and/or use the sidelink transmission power when performing sidelink transmission within the shared COT). In some examples, based on (e.g., in response to) the energy detection threshold (e.g., in response to receiving the COT sharing information indicative of the energy detection threshold), the second UE may determine (e.g., derive) a maximum sidelink transmit power (e.g. the second maximum sidelink transmit power) based on the energy detection threshold).
It would have been obvious to one of ordinary skill in the art at the time of the filing date to combine the disclosure of perform a channel access procedure for a sidelink transmission within the COT resources when COT is initiated by network, as disclosed by Niu, with the disclosure of receiving a sidelink maximum energy detection threshold and setting the energy detection threshold to the sidelink maximum energy detection threshold, as disclosed by Huang. The motivation to combine would have been to support LBT for sidelink transmission (Huang: e.g., ¶ [0002]).
Niu in view of Huang does not expressly disclose adjusting a default energy detection threshold by the sidelink energy detection threshold offset in response to receiving the sidelink energy detection threshold offset without the sidelink maximum energy detection threshold.
Wang discloses adjusting a default energy detection threshold by the sidelink energy detection threshold offset in response to receiving the sidelink energy detection threshold offset without the sidelink maximum energy detection threshold (e.g., ¶ [0144] In some example embodiments, the network device 110 may adjust an energy detection threshold used for a channel access procedure based on the power-related parameter (which may be a value proportional to the difference of the transmission powers). In some example embodiments, the network device 110 may use the power-related parameter as an offset to adjust the set maximum output power that is used to determine an energy detection threshold according to the communication specifications.).
It would have been obvious to one of ordinary skill in the art at the time of the filing date to combine the disclosure of receiving at least one of a sidelink maximum energy detection threshold or a sidelink energy detection threshold offset; setting an energy detection threshold to the sidelink maximum energy detection threshold in response to receiving the sidelink maximum energy detection threshold, as disclosed by Niu in view of Huang, with the disclosure of receiving a sidelink energy detection threshold offset, as disclosed by Wang. The motivation to combine would have been to support a solution of transmission of synchronization signal blocks (Bang: e.g., ¶ [0004]).
Regarding Claim 28, Niu discloses all the limitations of the method of claim 22.
The functional limitations of Claim 28 are similar to claim 21. Therefore, the reasoning used in the examination of claim 21 shall be applied to claim 28.
