+Idle Mode Paging procedure
+---------------------------

+
+  Figure 9 -  Idle Mode Paging flow
+
+As seen in the Figure 9,
+
+- When a Paging is received from CU and the Cell to be Paged is UP then DU APP will calculate Paging Frame(PF) and i_s(Index of Paging Ocassion/Slot) and groups the Paging of UEs falling on same PF/SFN together and stores in its Cell's Databse.
+
+- When a Slot Indication for SFN is received then DU APP extracts the Paging of all UEs whose PF is ahead by PAGING_DELTA and builds Paging RRC PDU. DU APP sends the same via DL PCCH Indication to MAC.
+
+- MAC forwards to SCH as PAGING INDICATION.
+
+- SCH stores the Page Message in its DB and when the SLOT_INDICATION for that SFN arrives, SCH performs scheduling and resource allocation for PDCCH (alongwith DCI 1_0 format) and PDSCH channels and sends to MAC through DL PAGING ALLOCATION message.
+
+- MAC forwards the PAGE to PHY in TX_Data.Request.
