Title: Method and apparatus for synchronizing and transporting data in wireless communication system
Inventor: STANWOOD KENNETH L
IPC: H04W80/02
Filed: 2007-08-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for transporting and synchronizing data between MAC and a physical communication protocol layer in a wireless communication system.  <P>SOLUTION: Depending on a length of a MAC packet to be transported, the present invention either fragments or concatenates the MAC packet when mapping to the physical layer.
