Allowable Subject Matter Claims 3, 5-7, 12, and 14-16 are objected to as being dependent upon a rejected base claim, but would be allowable if the Applicant rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is a statement of reasons for the indication of allowable subject matter: As to claim 3 and 12, the prior arts of record do not teach or reasonably suggest the limitation “resetting the value of the short CDRX cycle extension variable; incrementing a value of a short CDRX timer variable; determining whether the incremented value of the short CDRX timer variable equals the short CDRX timer threshold value; and starting a long CDRX cycle based on the results of the determining whether the incremented value of the short CDRX timer variable equals the short CDRX timer threshold value” with the claimed invention as a whole. As to claim 5 and 14, the prior arts of record do not teach or reasonably suggest the limitation “determining whether the incremented value of the early short CDRX cycle termination variable equals the early short CDRX cycle termination threshold value; and transmitting a second EH CDRX message to the RAN node based on results of the determining whether the incremented value of the early short CDRX cycle termination variable equals the early short CDRX cycle termination threshold value, the second EH CDRX message indicating a stop to the short CDRX cycle timer” with the claimed invention as a whole. As to claim 6 and 15, the prior arts of record do not teach or reasonably suggest the limitation “a value of the early short CDRX cycle termination threshold value is less than the value of the short CDRX timer threshold value” with the claimed invention as a whole. As to claim 7 and 16, the prior arts of record do not teach or reasonably suggest the limitation “determine the EH CDRX settings by determining whether the current stored energy capacity equals or exceeds the desired EH CDRX energy threshold value and the early long CDRX cycle termination threshold value at a start of an ON duration of a long CDRX cycle, and transmit a third EH CDRX message to the RAN node indicating an end of the long CDRX cycle” with the claimed invention as a whole.
