Abstract
A method and apparatus for performing H-ARQ transmission is described herein. Bits received on a first transmission are stored and combined with the bits received on later transmissions thereby increasing the likelihood of a correct decoding on later transmissions. Additionally, a plurality of coding schemes (e.g., Convolutional Codes, Block Turbo Codes, Convolutional Turbo Codes, Low Density Party Check Codes, . . . , etc.) are utilized, with an information element being reserved to signal what form of H-ARQ is being utilized.
Claims27
In a transmitter employing the IEEE 802.16 system protocol, a method for transmitting control information, the method comprising the steps of:
- determining an encoding type;
- transmitting control information within a Sub-packet Identifier (SPID) field, an encoder packet size (Nep) field, and a number of sub channels (Nsch) field, wherein the information transmitted within these fields is based on the encoding type;
- receiving data to be transmitted to a receiver;
- wherein the step of determining the encoding type comprises the step of determining the encoding type for the data to be transmitted to the receiver;
- and
- wherein the step of transmitting information comprises the step of transmitting a quantized set of information block size and resource allocation pairs within the Nep, and Nsch fields when Chase combining is being utilized.
In a receiver employing the IEEE 802.16 system protocol, a method comprising the steps of:
- determining an encoding type;
- receiving a message comprising a plurality of fields;
- utilizing the plurality of fields for first information when a first type of encoding is specified and utilizing the plurality of fields for second information when a second encoding type is specified;
- wherein the step of receiving the message comprises the step of receiving a message comprising a Sub-packet Identifier (SPID) field, an encoder packet size (Nep) field, and a number of sub channels (Nsch) field;
- and
- wherein the step of utilizing the plurality of fields comprises the step of utilizing a quantized set of information block size and resource allocation pairs within the Nep, and Nsch fields when Chase combining is being specified.
An apparatus comprising:
- logic circuitry determining an encoding type;
- and
- a transmitter transmitting information within a Sub-packet Identifier (SPID) field, an encoder packet size (Nep) field, and a number of sub channels (Nsch) field, wherein a type of information transmitted within the fields is based on the encoding type.
An apparatus comprising:
- a receiver receiving an over-the-air message comprising a plurality of fields;
- and
- logic circuitry determining an encoding type and utilizing the plurality of fields for first information when a first type of encoding is specified and utilizing the plurality of fields for second information when a second encoding type is specified.
