Abstract

Provided is a method and system for transmitting information. The method includes determining stream length information for at least one data stream to be transmitted and associating the stream length information with a system parameter message. The system parameter message including the associated stream length information is transmitted separately from the data stream. This process facilitates de-multiplexing of individual streams and the processing of stream data even if one or more individual streams are received in error.

First claim

What is claimed is:

1. A method for transmitting information within a super-frame, comprising:
determining a stream length indicator for each of a plurality of data streams to be transmitted, wherein a stream length for each of the data streams is based upon a quantity of medium access control (MAC) layer packets;
embedding each of the stream length indicators within a system parameter message; and
transmitting the system parameter message that includes the stream length indicators separately from the data streams transmitted in the super-frame, wherein the system parameter message is included within an overhead information symbols (OIS) channel that is located at the beginning of the super-frame.

2. The method of claim 1 , wherein the system parameter message is transmitted in accordance with first transmission characteristics and the data streams are transmitted in accordance with second transmission characteristics.

3. The method of claim 1 , wherein the system parameter message includes an indication of a location of each of the data streams.

4. A method of receiving information, comprising:
receiving, at a beginning of a super-frame, an overhead information symbols (OIS) channel comprising a system parameter message, the system parameter message including:
a stream length indicator for each of a plurality of transmitted data streams, wherein a stream length for each of the data streams is based upon a quantity of medium access control (MAC) layer packets and the system parameter message is received separately from the transmitted data streams transmitted in the super-frame;

recovering each of the stream length indicators from the received system parameter message; and
reading each of the transmitted data streams based on a corresponding stream length indicator.

5. The method of claim 4 , wherein the system parameter message includes an indication of a location of each of the data streams.

6. An apparatus for transmitting information within a super-frame, comprising:
means for determining a stream length indicator for each of a plurality of data streams to be transmitted, wherein a stream length for each of the data streams is based upon a quantity of medium access control (MAC) layer packets;
means for embedding each of the stream length indicators within a system parameter message; and
means for transmitting the system parameter message including the stream length indicators separately from the data stream transmitted in the super-frame, wherein the system parameter message is included within an overhead information symbols (OIS) channel that is located at the beginning of the super-frame.

7. The apparatus of claim 6 , wherein the system parameter message is transmitted in accordance with first transmission characteristics and the data streams are transmitted in accordance with second transmission characteristics.

8. The apparatus of claim 6 , wherein the system parameter message includes an indication of a location of each of the data streams.

9. A non-transitory computer-readable medium storing computer-executable code for transmitting information within a super-frame, the non-transitory computer-readable medium comprising:
code for determining a stream length indicator for each of a plurality of data streams to be transmitted, wherein a stream length for each of the data streams is based upon a quantity of medium access control (MAC) layer packets;
code for embedding each of the stream length indicators within a system parameter message; and
code for transmitting the system parameter message including the stream length indicators separately from the data streams transmitted in the super-frame, wherein the system parameter message is included within an overload information symbols (OIS) channel that is located at the beginning of the super-frame.

10. The non-transitory computer-readable of claim 9 , wherein the system parameter message is transmitted in accordance with first transmission characteristics and the data streams are transmitted in accordance with second transmission characteristics.

11. The non-transitory computer-readable medium of claim 9 , wherein the system parameter message includes an indication of a location of each of the data streams.

12. A transmission module for transmitting information within a super-frame, comprising:
a processor comprising:
a determination portion configured to determine a stream length indicator for each of a plurality of data streams to be transmitted, wherein a stream length for each of the data streams is based upon a quantity of medium access control (MAC) layer packets; and
an associating portion configured to embed each of the stream length indicators within a system parameter message; and

a transmitter configured to transmit the system parameter message including the stream length indicators separately from the data streams transmitted in the super-frame, wherein the system parameter message is included within an overhead information symbols (OIS) channel that is located at the beginning of the super-frame.

13. The transmission module of claim 12 , wherein the system parameter message includes an indication of a location of each of the data streams.

14. A system for transmitting information within a super-frame, comprising:
a processor having first and second logic portions, wherein the first logic portion determines a stream length indicator for each of a plurality of data streams to be transmitted, a stream length for each of the data streams is based upon a quantity of medium access control (MAC) layer packets, and the second logic portion embeds each of the stream length indicators within a system parameter message; and
a transmitter configured to transmit the system parameter message including the stream length indicator separately from the data streams transmitted in the super-frame, wherein the system parameter message is included within an overhead information symbols (OIS) channel that is located at the beginning of the super-frame.

15. The system of claim 14 , wherein the system parameter message includes an indication of a location of each of the data streams.
