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.

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 mecha
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; andtransmitting the frame without the protocol field. 2. The method as in claim 1, wherein the start of frame indicator is a predetermined sequence of bits, the method further comprising: if the portion of the IP packet contains the predetermined sequence of bits, inserting a classifier into the portion of the IP packet. 3. The method as in claim 2, wherein the classifier corresponds to an escape character. 4. The method as in claim 1, wherein the error checking mechanism is a frame check sequence. 5. A method for receiving framed packets in a wireless transmission system supporting broadcast transmissions, the method comprising: receiving a frame of a packet transmission wherein the frame contains a payload portion of an Internet Protocol (IP) packet and does not include a protocol field to identify a payload type, the frame having a start of frame portion, a payload portion, and an error check portion, the frame not including the protocol field;identifying the frame as a start frame in the packet transmission;verifying the frame using the error check portion of the frame; andprocessing the payload portion of the frame. 6. The method as in claim 5, wherein if the start of frame indicator is a predetermined sequence of bits, and wherein if the payload portion contains the predetermined sequence of bits, the payload portion further includes a classifier to identify the predetermined sequence of bits in the payload. 7. The method as in claim 6, wherein the classifier defines an escape character. 8. The method as in claim 6, further comprising: identifying the classifier in the payload not including protocol information to identify a payload type; andprocessing the payload without the classifier. 9. The method as in claim 5, wherein the error check portion is a frame check sequence. 10. An apparatus for framing packets in a wireless transmission system supporting broadcast transmissions, the apparatus comprising: means for generating a portion of an Internet Protocol (IP) packet for transmission;means for appending a start of frame indicator to the portion of the IP packet;means for applying an error checking mechanism to the portion of the IP packet;means for preparing a frame for transmission, having the start of frame indicator, the portion of the IP packet and the error checking mechanism and not including a protocol field to identify a payload type; andmeans for transmitting the frame without the protocol field. 11.
