Abstract
A wireless communication signal in Long Term Evolution (LTE) may be interleaved in a manner which permits a partitioning of a received inter-column bit-reversed interleaved code block for improved de-interleaving. The code block may be divided into equal subportions which may be simultaneously de-interleaved both forward and backward, and in parallel with other subportions. An even number of subportions may be provided. Dividing a received code block in this manner may improve de-interleaving performance.
Claims18
A method for wireless communication, comprising:
- receiving an inter-column bit-reversed interleaved code block;
- partitioning the received inter-column bit-reversed interleaved code block into a first portion and a second portion, the partitioning enabling de-interleaving of each portion independently from other portions in a first direction and a second direction, the second direction being opposite from the first direction;
- and
- de-interleaving each of the first portion and the second portion independently from other portions, wherein each of the first portion and the second portion is de-interleaved in the first direction and is simultaneously de-interleaved in the second direction.
An apparatus for wireless communication, the apparatus comprising:
- means for receiving an inter-column bit-reversed interleaved code block;
- means for partitioning the received inter-column bit-reversed interleaved code block into a first portion and a second portion, the partitioning enabling de-interleaving of each portion independently from other portions in a first direction and a second direction, the second direction being opposite from the first direction;
- and
- means for de-interleaving each of the first portion and the second portion independently from other portions, wherein each of the first portion and the second portion is de-interleaved in the first direction and is simultaneously de-interleaved in the second direction.
A computer program product for wireless communication, the computer program product comprising:
- a non-transitory computer-readable medium having non-transitory program code recorded thereon, the program code comprising:
- program code to receive an inter-column bit-reversed interleaved code block;
- program code to partition the received inter-column bit-reversed interleaved code block into a first portion and a second portion, the partitioning enabling de-interleaving of each portion independently from other portion in a first direction and a second direction, the second direction being opposite from the first direction;
- and
- program code to de-interleave each of the first portion and the second portion independently from other portions, wherein each of the first portion and the second portion is de-interleaved in the first direction and is simultaneously de-interleaved in the second direction.
An apparatus for wireless communication, the apparatus comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor being configured:
- to receive an inter-column bit-reversed interleaved code block;
- to partition the received inter-column bit-reversed interleaved code block into a first portion and a second portion, the partitioning enabling de-interleaving of each portion independently from other portions in a first direction and a second direction, the second direction being opposite from the first direction;
- and
- to de-interleave each of the first portion and the second portion independently from other portions, wherein each of the first portion and the second portion is de-interleaved in the first direction and is simultaneously de-interleaved in the second direction.
