Abstract

A method for deinterleaving a plurality of resource units (RUs) where each RU includes data and parameters. The method includes assigning each RU into one of a first deinterleaver and a second deinterleaver and storing the parameters of each respective RU to a respective buffer in an order. The method also includes processing the data of the respective RU in the one of the first deinterleaver and the second deinterleaver and upon completion of the processing of the data of a respective RU, outputting the data of the respective RU from the one of the first deinterleaver and the second deinterleaver into which the respective RU was assigned, outputting the parameters of the respective RU corresponding to one of the first deinterleaver and the second deinterleaver into which the respective RU was assigned, and aligning the parameters of the respective RU with the data of the respective RU based on the order of storage of the parameters in the respective buffer.

Dependent claims

A method for deinterleaving a plurality of resource units (RUs), each RU comprising data and parameters, the method comprising:

assigning each RU in the plurality of the RUs into one of a first deinterleaver and a second deinterleaver;
storing the parameters of each respective RU to a respective buffer corresponding to the one of the first deinterleaver and the second deinterleaver into which the respective RU was assigned, wherein the parameters are stored in an order in the buffer;
processing the data of the respective RU in the one of the first deinterleaver and the second deinterleaver;
and
upon completion of the processing of the data of a respective RU by the one of the first deinterleaver and the second deinterleaver:
outputting the data of the respective RU from the one of the first deinterleaver and the second deinterleaver into which the respective RU was assigned,
outputting the parameters of the respective RU from the respective buffer corresponding to the one of the first deinterleaver and the second deinterleaver into which the respective RU was assigned, and
aligning the parameters of the respective RU with the data of the respective RU based on the order of storage of the parameters in the respective buffer.
