Abstract
An apparatus and method for maximizing throughout for HARQ transmissions is provided. Systematic and prodeduralized RV selection is facilitated by determining the parameter “s” by using two important factors affecting the system throughout, specifically the coding gain varying according to the code rate and the balance between energy per systematic bit and energy per parity bit.
Claims29
An apparatus for selecting a redundancy version for performing transmissions according to a hybrid automatic retransmission request (HARQ) in a communications system, the apparatus comprising:
- a controller adapted to set a plurality of parameter values;
- and
- a processor adapted to select a redundancy version based on the plurality of parameter values and to transmit data using the selected redundancy version.
A method for selecting a redundancy version transmissions according to a hybrid automatic retransmission request (HARQ) in a communications system, the method comprising:
- setting a plurality of parameter values;
- selecting a redundancy version based on the plurality of parameter values;
- and
- transmitting data according to the selected redundancy version.
A method for maximizing throughput for transmissions according to a hybrid automatic retransmission request (HARQ) in a communications system, the method comprising:
- setting at least one parameter value to obtain an optimal redundancy version, the at least one parameter value set in consideration of a priority for systematic bits and parity bits, the priority dependent upon whether a transmission or re-transmission is being performed;
- and
- transmitting data according to the optimal redundancy version.
