Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claims 2-4 and 8-10 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claims 2-4 and 8-10 recite the limitation “determine in case” and/or “determine, in case.” This language is indefinite because the limitation is unclear regarding what is being determined, and because “in case” is typically use as a provision against something happening or being true. If the claims are suggesting conditional statements, more appropriate language would be to use “determine whether” or “determine, whether.”
For the purposes of examination, the claim limitations “determine in case” and “determine, in case” are interpreted as “determine whether” and “determine, whether” respectively.

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.

Regarding Claim 2, Zhou further discloses:
determining in case that downlink control information with a cyclic redundancy check scrambled by a power saving-radio network temporary identifier monitoring (Zhou, [0257], “A wireless device monitors PDCCH candidates in one or more of the following search spaces sets…a Type3-PDCCH CSS set configured by SearchSpace in PDCCH-Config with searchSpaceType=common for DCI formats with CRC scrambled by INT-RNTI, SFI-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, TPC-SRS-RNTI, CI-RNTI, or PS-RNTI”) is configured for an active downlink bandwidth part (Zhou, [0251], “In an example, a MAC entity may apply normal operations on an active BWP for an activated serving cell configured with a BWP comprising: transmitting on UL-SCH; transmitting on RACH; monitoring a PDCCH; transmitting PUCCH”, Zhou describes that a wireless device may monitor PDCCH candidates on an active BWP and in a search space set defined by a DCI format with CRC scrambled by PS-RNTI); wherein a DRX on-duration timer associated with a current DRX cycle pertaining to the unicast DRX is not started (Zhou, [353], “The wireless device may transmit the first CSI report for the MBS session during an active time of the MBS DRX configuration regardless of whether the wireless device is in an active time of the unicast DRX configuration"; [0365], “during the second active time (e.g., when the second DRX inactivity timer is running, when the second DRX on duration timer is running, or when the second DRX retransmission timer is running, etc.) of the unicast DRX configuration”, Zhou describes a UE can transmit a CSI report for a MBS session regardless of whether the device is in an active time of unicast DRX configuration. Zhou further describes active time of a unicast DRX configuration as when the DRX on duration timer is running); and determining, in case that the MAC entity is not in the active time of all the configured multicast DRXs (Zhou, [0320], “In an example, for the MBS DRX configuration, the Active Time of the MBS DRX may comprise a time during which the DRX on duration timer or the DRX inactivity timer of the MBS DRX configuration is running”) considering at least one of a multicast assignment, a DRX command MAC control element (CE) and a long DRX command MAC CE for the multicast received from the base station until 4 milliseconds prior to the current symbol in case that evaluating the active time of all the configured multicast DRXs (Zhou, [0310], “A DRX Command MAC control element or a Long DRX Command MAC control element may be received.

Zhou does not explicitly disclose:
determining in case that downlink control information with a cyclic redundancy check scrambled by a power saving-radio network temporary identifier monitoring is configured for an active downlink bandwidth part; determining in case that a current symbol occurs within a DRX on-duration timer duration; and determining, in case that the MAC entity is not in the active time of all the configured multicast DRXs considering at least one of a multicast assignment, a DRX command MAC control element (CE) and a long DRX command MAC CE for the multicast received from the base station until 4 milliseconds prior to the current symbol in case that evaluating the active time of all the configured multicast DRXs.
However, in the same field of endeavor, 38.321 discloses:
determining in case that downlink control information with a cyclic redundancy check scrambled by a power saving-radio network temporary identifier monitoring (38.321, [3.2], “DCP” is defined as “DCI with CRC scrambled by PS-RNTI”) is configured for an active downlink bandwidth part (38.321, [5.7, pg. 64], “if DCP monitoring is configured for the active DL BWP”); determining in case that a current symbol occurs within a DRX on-duration timer duration (38.321, [5.7, pg. 64], “if the current symbol n occurs within drx-onDurationTimer duration”); and determining, in case that the MAC entity is not in the active time of all the configured DRXs considering at least one of a multicast assignment, a DRX command MAC control element (CE) and a long DRX command MAC CE for the multicast received from the base station until 4 milliseconds prior to the current symbol in case that evaluating the active time of all the configured multicast DRXs (38.321, [5.7, pg. 64], “if the MAC entity would not be in Active Time considering grants/assignments/DRX Command MAC CE/Long DRX Command MAC CE received and Scheduling Request sent until 4 ms prior to symbol n when evaluating all DRX Active Time conditions as specified in this clause”).
Therefore, 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 method of Zhou to include the determining in case that downlink control information with a cyclic redundancy check scrambled by a power saving-radio network temporary identifier monitoring is configured for an active downlink bandwidth part; determining in case that a current symbol occurs within a DRX on-duration timer duration; and determining, in case that the MAC entity is not in the active time of all the configured multicast DRXs considering at least one of a multicast assignment, a DRX command MAC control element (CE) and a long DRX command MAC CE for the multicast received from the base station until 4 milliseconds prior to the current symbol in case that evaluating the active time of all the configured multicast DRXs as taught by 38.321. One would have been motivated to make this modification, with a reasonable expectation of success, so “the MAC entity may monitor the PDCCH discontinuously using the DRX operation” (38.321, [5.7, pg. 61]) according to 3GPP protocols.

Zhou further describes active time of a unicast DRX configuration as when the DRX on duration timer is running), and determine, in case that the MAC entity is not in the active time of all the configured multicast DRXs (Zhou, [0320], “In an example, for the MBS DRX configuration, the Active Time of the MBS DRX may comprise a time during which the DRX on duration timer or the DRX inactivity timer of the MBS DRX configuration is running”) considering at least one of a multicast assignment, a DRX command MAC control element (CE) and a long DRX command MAC CE for the multicast received from the base station until 4 milliseconds prior to the current symbol in case that evaluating the active time of all the configured multicast DRXs (Zhou, [0310], “A DRX Command MAC control element or a Long DRX Command MAC control element may be received. The MAC entity may stop drx-onDurationTimer and stop drx-InactivityTimer”; [0320], “In an example, for the MBS DRX configuration, the Active Time of the MBS DRX may comprise a time during which the DRX on duration timer or the DRX inactivity timer of the MBS DRX configuration is running”, Zhou discloses the Active Time of the MBS DRX may be based on whether the DRX on duration and DRX inactivity timer are running and further that when a DRX Command MAC CE or Long DRX Command MAC CE are received, the MAC entity may stop the drx-onDurationTimer and drx-InactivityTimer), wherein, in response to determining that the MAC entity is in the active time of all the configured multicast DRXs, transmit the at least one of the CSI, the semi-persistent CSI, the periodic SRS, and the semi-persistent SRS (Zhou, [353], “The wireless device may transmit the first CSI report for the MBS session during an active time of the MBS DRX configuration regardless of whether the wireless device is in an active time of the unicast DRX configuration”) to the base station (Zhou, [158], “The UE may provide the CSI report to the base station”) corresponding to the cell (Zhou, [0376], “In an example embodiment, when configured with a MBS DRX configuration in a cell, in addition to a unicast DRX configuration in the same cell, the wireless device may determine a CSI report transmission, for an MBS, based on a CSI masking parameter”).
Zhou does not explicitly disclose:
determine in case that downlink control information with a cyclic redundancy check scrambled by a power saving-radio network temporary identifier monitoring is configured for an active downlink bandwidth part; determine in case that a current symbol occurs within a DRX on-duration timer duration; and determine, in case that the MAC entity is not in the active time of all the configured multicast DRXs considering at least one of a multicast assignment, a DRX command MAC control element (CE) and a long DRX command MAC CE for the multicast received from the base station until 4 milliseconds prior to the current symbol in case that evaluating the active time of all the configured multicast DRXs.
However, in the same field of endeavor, 38.321 discloses:
determine in case that downlink control information with a cyclic redundancy check scrambled by a power saving-radio network temporary identifier monitoring (38.321, [3.2], “DCP” is defined as “DCI with CRC scrambled by PS-RNTI”) is configured for an active downlink bandwidth part (38.321, [5.7, pg. 64], “if DCP monitoring is configured for the active DL BWP”); determine, in case that a current symbol occurs within a DRX on-duration timer duration (38.321, [5.7, pg. 64], “if the current symbol n occurs within drx-onDurationTimer duration”); and determine, in case that the MAC entity is not in the active time of all the configured DRXs considering at least one of a multicast assignment, a DRX command MAC control element (CE) and a long DRX command MAC CE for the multicast received from the base station until 4 milliseconds prior to the current symbol in case that evaluating the active time of all the configured multicast DRXs (38.321, [5.7, pg. 64], “if the MAC entity would not be in Active Time considering grants/assignments/DRX Command MAC CE/Long DRX Command MAC CE received and Scheduling Request sent until 4 ms prior to symbol n when evaluating all DRX Active Time conditions as specified in this clause”).
Therefore, 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 method of Zhou to include the determine in case that downlink control information with a cyclic redundancy check scrambled by a power saving-radio network temporary identifier monitoring is configured for an active downlink bandwidth part; determine in case that a current symbol occurs within a DRX on-duration timer duration; and determine, in case that the MAC entity is not in the active time of all the configured multicast DRXs considering at least one of a multicast assignment, a DRX command MAC control element (CE) and a long DRX command MAC CE for the multicast received from the base station until 4 milliseconds prior to the current symbol in case that evaluating the active time of all the configured multicast DRXs as taught by 38.321. One would have been motivated to make this modification, with a reasonable expectation of success, so “the MAC entity may monitor the PDCCH discontinuously using the DRX operation” (38.321, [5.7, pg. 61]) according to 3GPP protocols.
Conclusion
