Abstract
Data packets transmitted over a wireless network are suppressed by hardware at the transmitting end and expanded on the receiving end. This conserves bandwidth as well as reduces the processing resource requirements in both the subscriber station and the base station. An extended header element is added to a data packet that is to be transmitted over the wireless network. The extended header element contains an index that is used along with an identifier to access a rule. The rule is used to determine which bytes are to be suppressed at the transmitter and expanded at the receiver.
Claims18
In a wireless communication system, a medium access control (MAC) to suppress a data packet header included in a data packet using hardware, the MAC comprising:
- a header parser to receive a data packet, the data packet including an extended header element;
- a memory interface to generate an address based on the extended header element and an identifier and to retrieve a descriptor from a memory based on the generated address;
- and
- a control unit to determine which bytes of the data packet are to be suppressed based on the descriptor.
In a wireless communication system, a medium access control (MAC) to expand a data packet header included in a data packet using hardware, the MAC comprising:
- a header parser to receive a data packet, the data packet including an extended header element;
- a memory interface to generate an address based on the extended header element and an identifier and to retrieve a descriptor from a memory based on the generated address;
- and
- a control unit to determine which of an unsuppressed byte from the header parser or a suppressed byte from the memory is to be transmitted based on the descriptor.
A wireless communication system to suppress and expand a data packet header included in a data packet using hardware, the wireless communication system comprising:
- a first medium access control (MAC) including
- first means for retrieving a descriptor from a first memory based on an address, wherein the address is based on an extended header element of the data packet and an identifier, and
- second means for suppressing at least one byte of the data packet header based on the descriptor;
- and
- a second MAC including
- third means for retrieving the descriptor from a second memory based on the address, and
- fourth means for expanding the data packet header based on the descriptor.
