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 set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied 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 2-4, 11, 14 and 20-21 are rejected under 35 U.S.C. 103 as being unpatentable over Xiaotao Ren (US 20240334344 A1) in view of Cheolkyu Shin et al (US 20240007968 A1).
For Claim 2, Ren discloses a power control method, wherein the plurality of powers further comprise a second transmission power, wherein the second transmission power is a maximum available transmission power determined based on a current channel busy ratio LCBR) level in a case of congestion control (Ren teaches, in ¶ 0284, that the parameter CBR refers to a channel occupation ratio in a resource pool in a historical time window measured by the terminal, and is a characterization parameter of a congestion degree of a current resource pool).
Ren fails to expressly teach a priority value of transmitted data.
However, Shin in analogous art discloses a priority value of transmitted data (Shin teaches, in ¶ 0258, that The value P.sub.MAX,CBR is determined with the CBR measured based on the SL RSSI and the priority of the data transmitted in the PSSCH transmission region).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the wireless communication system taught in Ren with the priority taught in Shin. The motivation is so that the maximum power for the congestion control is identified based on a channel busy ratio (CBR) measured for the PSSCH and a priority level [Shin: ¶ 0013, lines 9-11].
For Claim 3, Ren disclose all of the claimed subject matter with the exception that the priority value of the transmitted data is: a minimum of a priority value of the SL-PRS and a priority value of sidelink data; or, a preset priority value.
However, Shin in analogous art discloses that the priority value of the transmitted data is: a minimum of a priority value of the SL-PRS and a priority value of sidelink data (Shin teaches, in ¶ 0186, that in assumption 4, a minimum (min) priority for the positioning signal SL-PRS for the data transmission is assumed); or, a preset priority value (Shin teaches, in ¶ 0200, lines 1-8, that a transmission parameter range 1350 corresponding to a CBR range 1340, a CBR level 1330, and/or a priority 1320 of a transmit signal may be (pre-)configured through resource pool configuration 1310 values (e.g., the transmission parameter range 1350 corresponding to the CBR range 1340, the CBR level 1330, and/or the priority 1320 of the transmit signal) may be (pre-)configured in the UE before the UE is connected to the base station, and may be configured from the base station through the SIB).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the wireless communication system taught in Ren with the priority taught in Shin. The motivation is so that the maximum power for the congestion control is identified based on a channel busy ratio (CBR) measured for the PSSCH and a priority level [Shin: ¶ 0013, lines 9-11].
For Claim 4, Ren disclose all of the claimed subject matter with the exception that the priority value of the transmitted data is at least one of the following: the preset priority value in a case that the SL-PRS is not multiplexed with the sidelink data in one time unit; the minimum of the priority value of the SL-PRS and the priority of the sidelink data, or the preset priority vale in a case that the SL-PRS is multiplexed with the sidelink data in one time unit.
However, Shin in analogous art discloses that that the priority value of the transmitted data is at least one of the following: the preset priority value in a case that the SL-PRS is not multiplexed with the sidelink data in one time unit; the minimum of the priority value of the SL-PRS and the priority of the sidelink data (Shin teaches, in ¶ 0186, that in assumption 4, a minimum (min) priority for the positioning signal SL-PRS for the data transmission is assumed), or the preset priority vale in a case that the SL-PRS is multiplexed with the sidelink data in one time unit (Shin teaches, in ¶ 0265, that In Condition 3-4, the value P.sub.MAX,CBR is determined using the SL-PRS priority if the SL-PRS is TDMed with the data and transmitted and received in the PSSCH resource region).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the wireless communication system taught in Ren with the priority taught in Shin. The motivation is so that the maximum power for the congestion control is identified based on a channel busy ratio (CBR) measured for the PSSCH and a priority level [Shin: ¶ 0013, lines 9-11].
For Claim 11, Ren discloses a power control method, wherein the third transmission power is a minimum of the maximum transmission power and a second transmission power; wherein the second transmission power is a maximum available transmission power determined based on a current CBR level in a case of congestion control (Ren teaches, in ¶ 0284, that the parameter CBR refers to a channel occupation ratio in a resource pool in a historical time window measured by the terminal, and is a characterization parameter of a congestion degree of a current resource pool).
Ren fails to expressly teach a priority value of transmitted data.
However, Shin in analogous art discloses a priority value of transmitted data (Shin teaches, in ¶ 0258, that The value P.sub.MAX,CBR is determined with the CBR measured based on the SL RSSI and the priority of the data transmitted in the PSSCH transmission region).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the wireless communication system taught in Ren with the priority taught in Shin. The motivation is so that the maximum power for the congestion control is identified based on a channel busy ratio (CBR) measured for the PSSCH and a priority level [Shin: ¶ 0013, lines 9-11].
For Claim 14, Ren discloses a power control method, wherein the fourth transmission power is a minimum of the maximum transmission power and a second transmission power; wherein the second transmission power is a maximum available transmission power determined based on a current CBR level in a case of congestion control (Ren teaches, in ¶ 0284, that the parameter CBR refers to a channel occupation ratio in a resource pool in a historical time window measured by the terminal, and is a characterization parameter of a congestion degree of a current resource pool).
Ren fails to expressly teach a priority value of transmitted data.
However, Shin in analogous art discloses a priority value of transmitted data (Shin teaches, in ¶ 0258, that The value P.sub.MAX,CBR is determined with the CBR measured based on the SL RSSI and the priority of the data transmitted in the PSSCH transmission region).

The motivation is so that the maximum power for the congestion control is identified based on a channel busy ratio (CBR) measured for the PSSCH and a priority level [Shin: ¶ 0013, lines 9-11].

For Claim 21, please refer to the rejection of Claim 3 above.
