Question: In RRC_IDLE or RRC_INACTIVE state, how does a UE determine whether to monitor a specific paging occasion based on DCI format 2_7?
Option 1: By checking the payload size and comparing it with a predefined threshold.
Option 2: Based on the number of subgroups per paging occasion and its own subgroup index.
Option 3: Through a random access procedure initiated by the UE itself.
Option 4: By evaluating the value of a specific bit in the paging indication field of DCI format 2_7, which is determined by the paging occasion index and predefined parameters.
Explanation: The correct answer is Option 4 because the UE determines whether to monitor a paging occasion by checking the value of a specific bit in the DCI format 2_7's paging indication field, calculated based on the paging occasion index and other predefined parameters. If the value is '1', the UE monitors the corresponding paging occasion; otherwise, it does not, ensuring efficient management of paging and power conservation.
