assigning, by the processing system (He, Fig. 12, line 25-26, application processor and a graphics processor is processing system), more special time slots to the UE to provide the low-latency service to the UE. (Pederson, Abstract discloses URLLC, Introduction, page 2 discloses advanced NR system-level simulations for the challenging use cases with ultra-reliable low latency communication (URLLC), URLLC is low-latency service)
Regarding Claim 20, The combination of He and Pederson disclose the method of claim 16, comprising:
receiving, by the processing system (He, Fig. 12, line 25-26, application processor and a graphics processor is processing system), information about interference on one of a downlink and an uplink; (He, page 7 of 45, line 10 to line 34, and page 8 of 45 enhanced inter-cell interference coordination (eICIC)/interference/mitigation of interference, Fig. 3, page 10, line 15 to page 12, line 22; page 10 lines 15-16 disclose, and Fig. 3 illustrates uplink downlink (UL-DL) interference due to non-aligned UL-DL reconfiguration switching points, Fig. 3, page 10, line 17-19, techniques for DL-UL interference mitigation, UL-DL reconfigurations be performed synchronously in order to avoid DL-UL interference)and
muting, by the processing system (He, Fig. 12, line 25-26, application processor and a graphics processor is processing system), transmission on one or more selected downlinks or one or more uplinks to limit the interference. (He, page 7 of 45, line 10 to line 34, and page 8 of 45 enhanced inter-cell interference coordination (eICIC)/interference/mitigation of interference, Fig. 3, page 10, line 15 to page 12, line 22; page 10 lines 15-16 disclose, and Fig. 3 illustrates uplink downlink (UL-DL) interference due to non-aligned UL-DL reconfiguration switching points, Fig. 3, page 10, line 17-19, techniques for DL-UL interference mitigation, UL-DL reconfigurations be performed synchronously in order to avoid DL-UL interference)
8. Claims 10 is rejected under 35 U.S.C. 103 as being unpatentable over He et al., (International Publication Number: WO 2014/210212 A1), and Pedersen et al., (Advancements in 5G New Radio TDD Cross Link Interference Mitigation, IEEE Wireless Communications, August 2021), in view of Wifvesson et al., (International Publication Number: WO 2020/178159 A1).
Regarding Claim 10, The combination of He and Pederson disclose the device of claim 9 (He, Fig. 12, page 19, lines 8-10, UE/MS, line 22, wireless device), wherein the operations further comprise: (He, Fig. 12, page 19, lines 8-10, UE/MS, line 22, wireless device, UE implements operations)
selecting the initial TDD configuration for the UE based on the service to be accessed by the UE. (He, (57) Abstract, Time Division Duplex (TDD) uplink-downlink (DL-UL) reconfiguration, page 2, line 10 to line 18 TDD for DL or UL, Fig. 1, line 17 to page 9, line 22, Figs. 2A-2C, page 9, line 24 to page 10, line 14, Fig. 10, page 17 line 8 to page 18 line 10)
He and Pedersen do not explicitly disclose following:
receiving a packet data unit (PDU) establishment communication from the UE;
determining, based on the PDU establishment communication, a service to be accessed by the UE;
However, He and Pedersen in view of Wifvesson disclose following:
receiving a packet data unit (PDU) establishment communication from the UE; (Wifvesson, (WO 2020/178159 A1), (57) Abstract discloses protocol data unit (PDU) session establishment, paragraphs [0001], [0031]-[0037], [0041]-[0054], Figs. 7-10, paragraphs [0083]-[0125] illustrate PDU session establishment/ PDU session establishment procedure and describe in details, paragraph [0031] discloses receiving a first request to establish a first protocol data unit (PDU) session between a user equipment (UE) and a user plane function in the core network)
determining, based on the PDU establishment communication, a service to be accessed by the UE; (Wifvesson, (WO 2020/178159 A1), (57) Abstract discloses protocol data unit (PDU) session establishment, paragraphs [0001], [0031]-[0037], [0041]-[0054], Figs. 7-10, paragraphs [0083]-[0125] illustrate PDU session establishment/ PDU session establishment procedure and describe in details)
It would have been obvious to one of the ordinary skill in the art to be motivated to combine the teachings of He and Pedersen before the effective filing date of the claimed invention with that of Wifvesson so that receiving a packet data unit (PDU) establishment communication from the UE; determining, based on the PDU establishment communication, a service to be accessed by the UE be included in the device (i.e. UE). The motivation to combine the teachings of Wifvesson would be able to achieve maximum supported data rate for integrity protection provided by the UE. Further, it would ensure high reliability requirements. (Wifvesson, Abstract, paragraphs [0001]-[0054])
