Status of Claims
2. This Office Action is in response to the application filed on 05/26/2026. Claims 1 and through 20 are presently pending and are presented for examination.
3. 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 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.
Claim Rejections - 35 USC § 103
4. 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.
Claims 1-20 are rejected under 35 U.S.C. 103 as being unpatentable over Kim (US 2024/03146652 A1) in view of Kim (US 2024/0023195 A1-hereafter Kim-195).
For claim 1 Kim teaches a method comprising:
receiving, by a wireless device, a first message comprising a request associated with a wireless device capability (claim 1 “transmitting, to a base station, capability information associated with the user device”);
sending a second message indicating a capability of the wireless device (claim 1 “transmitting, to a base station, capability information associated with the user device”), wherein the second message comprises:
a first parameter indicating whether the wireless device supports a cell discontinuous transmission (DTX) configuration by radio resource control (RRC) messaging (claim 1 “receiving, from the base station, a first radio resource control (RRC) message, wherein the first RRC message comprises: parameters”); and
a second parameter indicating whether the wireless device supports an activation of the cell DTX configuration by downlink control information (DCI) (claim 1 “receiving, DCI”);
receiving an RRC message comprising configuration parameters of the cell DTX configuration (paragraph 7 “RRC message comprise at least one configuration parameter associated with a serving cell”); and
Kim does explicitly teach receiving the DCI indicating activation of the cell DTX configuration.
However, Kim-195 teaches RRC message includes DTX configuration and DCI include information on DTX activation/operation (Kim-195: paragraphs 11-15 and 173-174). In addition, Kim-195 teaches transmitting a message including camping restriction information, wherein the camping restriction information indicates whether the base station supports a network energy saving (NES) function, and when the base station supports the NES function, the base station may perform at least one of the DTX
operation or the DRX operation (Kim-195: paragraph 19).
Thus, it would have been obvious to a person of ordinary skill in the art before the effective filing date of claimed invention to use the teachings of Kim-195 in the mobility based system of Kim in order to support network energy saving (Kim-195: paragraphs 19 and 177).
