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 may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made.
Claims 1-2, 5-9,11-13 and 16-20 are rejected under 35 U.S.C. 103 as being unpatentable over Chen et al. (WO-2018223349-A1) in view of Chatterjee et al. (US-20190149269-A1) further in view of Luo et al. (US-20210250786-A1).
Regarding claim 1, Chen et al. disclose a method for controlling uplink (UL), UL, transmission, carried out in a user equipment (UE), UE, comprising a radio unit configured for communication with a wireless network, comprising: receiving information from the wireless network, which information identifies scheduling of one or more downlink (DL) , DL, reference signals, usable for estimating a time and/or frequency error of the radio unit (Paragraph 0021 discloses transmission of the CSI-RS trigger by the base station to the UE, indicating transmission of CSI-RS after a timing delay); wherein the information indicates timing of a first reference signal prior to or during the scheduled transmission pattern (Paragraph 0021 discloses the timing or time delay corresponding to CSI-RS transmission and UL data transmission, where by collisions are possible).
Chen et al. fail to explicitly disclose receiving, from the wireless network, scheduling of an UL transmission pattern for transmission of a plurality of repeated transmissions; postponing one of the plurality of repeated transmissions for a first duration comprising the first reference signal, responsive to the timing of the first reference signal occurring during the scheduled transmission pattern, and resuming transmission of the plurality of repeated transmissions according to said transmit pattern after said first duration.
However, in an analogous art, Chatterjee et al. teaches receiving, from the wireless network, scheduling of an UL transmission pattern for transmission of a plurality of repeated transmissions (Paragraph 0096 discloses “In some embodiments, if the UE 102 is scheduled by a DCI format 0_1 to transmit a PUSCH over a plurality of slots;” Paragraph 0111 discloses “UE behavior on handling conflict between periodic transmission and DL/UL transmission from semi-static assignment;”); postponing one of the plurality of repeated transmissions for a first duration comprising the first reference signal, responsive to the timing of the first reference signal occurring during the scheduled transmission pattern, and resuming transmission of the plurality of repeated transmissions according to said transmit pattern after said first duration (Paragraph 0103 discloses “In some embodiments, the UE 102 may, for a dynamically triggered multi-slot/mini-slot transmission/reception (Tx/Rx), when a number of available downlink (DL) or uplink (UL) symbols in each slot or mini-slot is less than a duration indicated by a downlink control information (DCI) of a DL grant or a UL grant: postpone transmission of one or more uplink elements; and/or postpone reception of one or more downlink elements.”. Paragraph 0115 discloses “ In some embodiments, in case of conflict between periodic transmission and DL/UL transmission from semi-static assignment, the UE 102 may postpone the measurement or measurement related transmission. For instance, the UE 102 may wait for the next available opportunity (in occasions which are configured by higher layers) for measurement related transmission in order to avoid collision between measurement related transmission/reception and semi-static DL/UL assignment.”).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to have modified Chen et al. to incorporate the teachings of Chatterjee et al., to receive from the wireless network, scheduling of an UL transmission pattern and to postponing one of the plurality of repeated transmissions for a first duration comprising the first reference signal , in order to implement mechanisms that enhance and support improved performance by minimizing interference.
Chen et al. and Chatterjee et al. fail to explicitly disclose receiving the first reference signal to estimate said time and/or frequency error.
However, in an analogous art, Luo et al. teaches receiving the first reference signal to estimate said time and/or frequency error (Paragraph 0083 discloses “…the UE 115-a may use the associated Periodic/Semi-Periodic Tracking Reference Signal resources to measure associated TRSs and track transmit/receive beam beams and estimate time and frequency error.”).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to have modified Chen et al. and Chatterjee et al. to incorporate the teachings of Luo et al., to receive and use the tracking reference signal to estimate time and frequency error, in order to synchronize UEs local oscillator frequency with the base station frequency.

Chen et al. fail to explicitly disclose controlling the radio unit based on a control rule, responsive to the timing of the first reference signal occurring during the scheduled transmission pattern, to perform the steps of dropping one of the plurality of repeated transmissions or the postponing one of the plurality of repeated transmissions for the first duration.
However, in an analogous art, Chatterjee et al. teaches controlling the radio unit based on a control rule, responsive to the timing of the first reference signal occurring during the scheduled transmission pattern, to perform the steps of dropping one of the plurality of repeated transmissions (Paragraph 0122 discloses “ In some embodiments, the UE 102 may drop or cancel the transmission of UL channels/signals or reception of DL channels/signals for all multi-slot/mini-slot Tx/Rx for that aggregated Tx/Rx. ”) or the postponing one of the plurality of repeated transmissions for the first duration (Paragraph 0103 discloses “In some embodiments, the UE 102 may, for a dynamically triggered multi-slot/mini-slot transmission/reception (Tx/Rx), when a number of available downlink (DL) or uplink (UL) symbols in each slot or mini-slot is less than a duration indicated by a downlink control information (DCI) of a DL grant or a UL grant: postpone transmission of one or more uplink elements; and/or postpone reception of one or more downlink elements.”. Paragraph 0115 discloses “ In some embodiments, in case of conflict between periodic transmission and DL/UL transmission from semi-static assignment, the UE 102 may postpone the measurement or measurement related transmission. For instance, the UE 102 may wait for the next available opportunity (in occasions which are configured by higher layers) for measurement related transmission in order to avoid collision between measurement related transmission/reception and semi-static DL/UL assignment.”).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filling date of the claimed invention to have modified Chen et al. and Luo et al. to incorporate the teachings of Chatterjee et al., to facilitate the dropping or postponing of repeated UL transmissions responsive to scheduled reference signals, in order to implement mechanisms that enhance and support improved downlink performance by minimizing interference.
