 POs in a DRX cycle is configurable via SI and a network may distribute UEs into those POs based on their UE_IDs. When in RRC_CONNECTED state, the UE monitors the PCHs in any PO signaled in the SI for SI change indication and public warning system notification. In the case of bandwidth adaptation, a UE in RRC_CONNECTED state only monitors PCHs on the active BWP with common search space configured (see Chapter 4). To optimize the paging procedure for the UEs in CM-IDLE state, upon UE context release, the NG-RAN node may provide the AMF with a list of recommended cells and NG-RAN nodes as assistance information for subsequent paging of the UE. The AMF may further provide paging attempt information consisting of a paging attempt count and the intended number of paging attempts and possibly the next paging area scope. If paging attempt infor- mation is included in the paging message, each paged NG-RAN node receives the same information during a paging attempt. The paging attempt count is increased by one at each new paging attempt. The next paging area scope, when present, indicates whether the AMF intends to modify the paging area currently selected at the next paging attempt. If the UE has changed its state to CM-CONNECTED, the paging attempt count is reset [8]. To optimize the paging procedure for the UEs in RRC_INACTIVE state, upon RAN-initiated paging, the serving NG-RAN node provides the RAN paging area informa- tion. The serving NG-RAN node may also provide the RAN paging attempt information. Each paged NG-RAN node receives the same RAN paging attempt information during a paging attempt with the following content: paging attempt count, the intended number of paging attempts and the next paging area scope. The paging attempt count is increased by 270 Chapter 2 one at each new paging attempt. The next paging area scope, when present, indicates whether the serving NG_RAN node plans to modify the RAN paging area currently selected for the next paging attempt. If the UE leaves RRC_INACTIVE state, the paging attempt
