Abstract
In the method of rate-matching, software is used to calculate at least one rate-matching parameter for data, and dedicated hardware is used to perform at least one of a puncturing and repetition process on data based on the calculated rate-matching parameter. In rate de-matching, software is again used to calculate at least one rate de-matching parameter for received data, and dedicated hardware is used to compensate for puncturing and repetition based on the calculated rate de-matching parameter.
Claims8
An apparatus for rate-matching, comprising:
- a processor calculating at least one rate-matching parameter for data;
- a selector receiving a current data, a previous data and an output data, the selector configured to selectively perform at least one of a puncturing process and a repetition process;
- and
- a state machine circuit receiving the calculated rate matching parameters and for controlling the selector based on the calculated rate matching parameters.
2-21. (canceled)
An apparatus for rate de-matching, comprising:
- a processor calculating at least one rate de-matching parameter for data;
- a controller receiving the at least one rate de-matching parameter and preparing setup parameters for a state machine circuit;
- the state machine circuit receiving the calculated rate de-matching parameters from the controller and configured to control a selector based on the calculated rate de-matching parameters;
- and
- the selector receiving a data selection signal from the state machine and configured to output one of a zero value, output from a bit clamp, and a puncture/replace bit based on the data selection signal.
