Question: What is the value of `AM_Window_Size` when a 16-bit Sequence Number (SN) is used in an AM RLC entity?
Option 1: 512
Option 2: 32768
Option 3: 1024
Option 4: 65536
Explanation: In the context of Evolved Universal Terrestrial Radio Access (E-UTRA) and specifically for the Radio Link Control (RLC) protocol, `AM_Window_Size` is crucial for both transmitting and receiving sides of an Acknowledged Mode (AM) RLC entity. When a 16-bit SN is utilized, the defined value for `AM_Window_Size` increases to accommodate the larger sequence number space, ensuring efficient handling of the increased range of possible sequence numbers. Thus, with a 16-bit SN, `AM_Window_Size` is set to **32768**.
