Method and apparatus for transmission framing in a wireless communication system

摘要

Method and apparatus for framing in a wireless transmission system supporting broadcast transmissions. A framing format incorporates fields specific to a uni-directional transmission and reduces the overhead of the system. One embodiment employs a version of HDLC having a start of frame field and an error checking mechanism attached to the payload of each frame, wherein protocol information is not transmitted with each individual frame.

主权项

1. A method for framing packets in a wireless transmission system supporting broadcast transmissions, the method comprising:
generating a portion of an Internet Protocol (IP) packet for transmission; appending a start of frame indicator to the portion of the IP packet; applying an error checking mechanism to the portion of the IP packet not including a protocol field to identify a payload type; preparing a frame for transmission, having the start of frame indicator, the portion of the IP packet, and the error checking mechanism; and transmitting the frame without the protocol field.
