Abstract
The invention provides a method for operating a hybrid automatic repeat request communication system wherein it is determined whether a receiver can process a data packet, and a self-decode request associated with the data packet is sent based on the determination.
Claims33
A method of operating a hybrid automatic repeat request communication system in a receiver comprising:
- determining whether the receiver can process a data packet;
- and
- sending a self-decode request associated with the data packet based on the determination.
A hybrid automatic repeat request communication system comprising:
- means for determining whether a receiver can process a data packet;
- and
- means for sending a self-decode request associated with the data packet based on the determination.
A computer usable medium including a program for operating a hybrid automatic repeat request communication system comprising:
- computer program code for determining whether a receiver can process a data packet;
- and
- computer program code for sending a self-decode request associated with the data packet based on the determination.
A method of operating a hybrid automatic repeat request communication system comprising:
- determining whether a self-decode request has been received at a transmitter;
- and
- generating a self-decodable data packet at the transmitter based on the self-decode request determination.
A hybrid automatic repeat request communication system comprising:
- means for determining whether a self-decode request has been received at a transmitter;
- and
- means for generating a self-decodable data packet at the transmitter based on the self-decode request determination.
A computer usable medium including a program for operating a hybrid automatic repeat request communication system comprising:
- computer program code for determining whether a self-decode request has been received at a transmitter;
- and
- computer program code for generating a self-decodable data packet at the transmitter based on the self-decode request determination.
A hybrid automatic repeat request communication device in a receiver comprising:
- a hybrid automatic repeat request buffer control unit;
- a pool of memory operably connected to the hybrid automatic repeat request buffer control unit to manage the pool of memory;
- a combine and store unit operably connected to the hybrid automatic repeat request buffer control unit to generate a channel decoder input based on a data packet;
- and
- channel decoder operably connected to the combine and store unit to process the channel decoder input;
- wherein the data packet is stored in the pool of memory in response to a hybrid automatic repeat request buffer memory determination.
A hybrid automatic repeat request communication device in a transmitter comprising:
- a self-decode request latch to provide an encoding scheme selection input in response to a self-decode request;
- an encoder control unit operably connected to the self-decode request latch to select an encoding scheme associated with an input data packet based on the encoding scheme selection input;
- and
- channel encoder operably connected to the encoder control unit to encode the input data packet;
- wherein the input data packet is encoded as a self-decodable data packet by the channel encoder in response to the self-decode request.
