  • Publication number: 20200221322
    Abstract: Methods, systems, and devices for wireless communication are disclosed. Flexible interleaving configurations may be employed to support various operations, including beamforming. Flexible interleaving may include dynamically or semi-statically determining a combination of bit-level, tone-level, tone-group level, or other interleaving technique for one or more transmissions. The interleaving configuration may be based on delay spread, a coherence bandwidth, a signal to noise ratio, a Doppler spread, or a combination thereof. An interleaving configuration may be a determination may be made by a base station or some other network entity and explicitly signaled to another device. Additionally or alternatively, the determination may be made based on one or more implicit rules, which may be based on a variety of factors (e.g., available bandwidth, modulation and coding scheme (MCS), code block (CB) size). Further, interleaving may be enabled (or disabled) under certain conditions.

  • Patent number: 10686038
    Abstract: An RC-IGBT includes a semiconductor body incorporating a field stop zone where the base region and the field stop zone are both formed using an epitaxial process and the field stop zone has an enhanced doping profile to realize improved soft-switching performance for the semiconductor device. In alternate embodiments, RC-IGBT device, including the epitaxial layer field stop zone, are realized through a fabrication process that uses front side processing only to form the backside contact regions and the front side device region. The fabrication method forms an RC-IGBT device using front side processing to form the backside contact regions and then using wafer bonding process to flip the semiconductor structure onto a carrier wafer so that front side processing is used again to form the device region.
