Rate matching with multiple code block sizes
Bits included in each code block of a transport block can be stored to an associated circular buffer and transmitted over a channel.

Furthermore, the number of bits transmitted from each circular buffer can be constrained by an aggregate budget for all circular buffers and can be further constrained to be an integer multiple of a modulation order for the transport block. |

Method for manufacturing a transistor having a sharp junction by forming raised source-drain regions before forming gate regions and corresponding transistor produced by said method
A transistor device is fabricated by growing an epitaxial layer of semiconductor material on a semiconductor layer and forming an opening extending through the epitaxial layer at a position where a gate is to be located. This opening provides, from the epitaxial layer, a source epitaxial region on one side of the opening and a drain epitaxial region on an opposite side of the opening. The source epitaxial region and a first portion of the semiconductor layer underlying the source epitaxial region are then converted into a transistor source region. Additionally, the drain epitaxial region and a second portion of the semiconductor layer underlying the drain epitaxial region are converted into a transistor drain region. A third portion of the semiconductor layer between the transistor source and drain regions forms a transistor channel region. A transistor gate electrode is then formed in the opening above the transistor channel region. |
