Abstract: Various aspects described herein relate to techniques for rate matching and interleaving in wireless communications (e.g., 5G NR). In an example, a method described herein includes encoding one or more information bits to generate a first codeblock, rate matching the first codeblock to generate a second codeblock, segmenting, using bit distribution, the second codeblock into one or more sub-blocks each having a plurality of bits. The method further includes interleaving the plurality of bits on each of the one or more sub-blocks, concatenating, using bit collection, the one or more sub-blocks to generate a third codeblock in response to the interleaving, and transmitting a signal using the third codeblock.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for decoding low density parity check (LDPC) codes, and more particularly to a deeply-pipelined layered LDPC decoder architecture for high decoding throughputs. Accordingly, aspects of the present disclosure provide techniques for reducing delays in a processing pipeline by, in some cases, relaxing a dependency between updating bit log likelihood ratios (LLRs) and computing a posteriori LLRs.

Abstract: Operational mode changes in a system-on-a-chip (SoC) integrated circuit in a complex device such as a mobile phone cause spikes in current demand which can cause voltage droops that disrupt operation of the SoC. A hybrid parallel power supply capacitively couples a switching-mode power supply and a low-dropout voltage regulator in parallel to provide high efficiency and fast response times. The low-dropout voltage regulator may include a class-AB operational transconductance amplifier driving the coupling capacitor. The switching-mode power supply and the low-dropout voltage regulator can regulate their outputs to slightly difference voltage levels. This can allow the switching-mode power supply to supply most of the SoC's current demands.
Abstract translation: 诸如移动电话等复杂设备的片上系统芯片(SoC)集成电路的运行模式变化会导致电流需求的尖峰,从而导致电压下降,从而破坏了SoC的运行。 混合并联电源并联电容耦合开关电源和低压差稳压器,以提供高效率和快速的响应时间。 低压差稳压器可以包括驱动耦合电容器的AB类运算跨导放大器。 开关电源和低压差稳压器可以将其输出调节为稍微不同的电压电平。 这可以允许开关电源供应大部分SoC的当前需求。
