Abstract
Method and apparatus for header compression in a wireless communication system supporting broadcast transmissions. The system periodically provides a header decompression message sufficient for a receiver to decompress the header. The decompression message transmission period is determined to avoid delay in accessing a broadcast session.
Claims12
In a wireless communication system supporting a uni-directional transmission, a method comprising:
- generating a payload transmission frame;
- determining a header for the payload transmission frame;
- compressing the header using a first format;
- and
- placing at least one parameter for the first format in a decompression information segment, the at least one parameter configured to initialize decompression of the header and at least a subsequent header of a subsequent payload transmission frame, wherein the decompression information segment is independent from any payload transmission frame, and the decompression information segment is queued for transmission on the same channel as the payload transmission frame and regularly interleaved between broadcast content comprising a plurality of compressed headers and payload frames in a broadcast stream.

In a wireless communication system supporting a uni-directional transmission, a method comprising:
- receiving a payload transmission frame, the payload transmission frame having a header compressed using a first format;
- receiving at least one parameter describing the first format in a decompression information segment, the at least one parameter configured to initialize decompression of the header and at least a subsequent header of a subsequent payload transmission frame, wherein the decompression information segment is independent from any payload transmission frame, and the decompression information segment is received on the same channel as the payload transmission frame and regularly interleaved between broadcast content comprising a plurality of compressed headers and payload frames in a broadcast stream;
- and
- decompressing the payload transmission frame using the first format.
