Claims 4, 5 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Wang, in view of Ye and in view of Harada et al (US 2022/0330239, hereinafter Harada).
Regarding claims 4 and 15, Wang discloses the method/apparatus of claim 1/13, but not wherein the indication comprises a demodulation reference signal (DMRS) encoding. Harada discloses a BS transmitting a specific PDCCH with a specific DMRS notifying the start of a COT that is initiated by the BS, Para [0047]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to utilize the techniques taught by Harada in the system of Wang and Ye in order to perform efficient transmission while keeping LBT opportunities with appropriate granularities.
Regarding claim 5, Wang discloses the method of claim 4, but not wherein, responsive to the DMRS encoding being a first DMRS encoding, the network node is using the network-initiated COT, and wherein, responsive to the DMRS encoding being a second DMRS encoding different from the first DMRS encoding, the network node is sharing the UE-initiated COT. Harada discloses a BS transmitting a specific PDCCH with a specific DMRS notifying the start of a COT that is initiated by the BS, Para [0047], where a COT not initiated by the BS would not use the specific DMRS value. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to utilize the techniques taught by Harada in the system of Wang in order to perform efficient transmission while keeping LBT opportunities with appropriate granularities.
Response to Arguments
Applicant's arguments filed 4/13/2026 have been fully considered but they are not persuasive. The Applicant amends the limitations in the claims and argues the Wang reference does not disclose the amended limitations. Applicant amends the claims to include a limitation of indicating that the network node is sharing the UE-initiated COT during a fixed frame period (FFP) associated with the apparatus, in an event that the apparatus has signaled an indication of a sharing, that the network node uses the UE-initiated COT or the network node explicitly signals the network node is using the UE-initiated COT. In response, arguments are moot in view of a new reference being used in the current office action. Applicant also argues over other independent claim 8. Applicant argues the Wang, Calcev and WU references do not disclose the limitations in claim 8, particularly the DCI has a C-RNTI for dynamic grant or CS-RNTI for CG retransmissions. In response, a new reference explicitly discloses this feature, making the arguments moot.
