Question: What are the key components that contribute to the cell re-selection delay in a UE's (User Equipment) process of camping on a new cell and initiating a Location Registration via RRC CONNECTION REQUEST?
Option 1: eDRX cycle + Random Access Response Time + SIB (System Information Block) decoding time
Option 2: Paging Load + Uplink Data Transmission Time + Handover Preparation Time
Option 3: Cell Identification Time + Authentication Procedure Time + Encryption Setup Time
Option 4: eDRX cycle + PTW (Paging Time Window) + TSI (Maximum repetition period of relevant system info blocks)
Explanation: The correct answer, Option 4, accurately reflects the components that contribute to cell re-selection delay. These include: eDRX cycle (extended Discontinuous Reception cycle for power conservation), PTW (Paging Time Window for receiving paging messages), and TSI (Maximum repetition period of relevant system info blocks for camping on a new cell). These directly impact the time for a UE to complete cell re-selection and initiate Location Registration.
