  • Publication number: 20200137102
    Abstract: In an embodiment, a management system obtains a criticality rules table that includes a plurality of rules mapped to corresponding criticality scores indicative of a level of risk in the event that an associated asset of a managed network is compromised by a third party. The one embodiment, the criticality rules table is updated based upon machine learning and/or feedback from an operator of the managed network. In another embodiment, the criticality rules table is used to assign one or more criticality scores to one or more assets based on one or more attributes of one or more assets, and the criticality rules table.

  • Publication number: 20200014405
    Abstract: Apparatus and methods are provided for polar code sub-block interleaving and bit selection. In one novel aspect, middle-part interlaced sub-block interleaving is provided for polar code interleaving. In one embodiment, the middle part of the polar code is interlaced and generates the interleaved polar code. In another embodiment, the lower part and the upper part are also sub-block interleaved with the middle-part interlaced method. In another novel, rate-dependent unified bit selection is provided. The bit selection is categorized into three operation categories of repetition, puncturing and the shortening. Each category follows unified bit selection rule with different categories differ only in the access scheme. In one embodiment, the circular buffer is used for bit selection.

  • Patent number: 10498481
    Abstract: A method of new radio physical broadcast channel (NR-PBCH) bit mapping is proposed to improve for NR-PBCH decoding performance under Polar codes. NR-PBCH carries 32 information bits and 24 CRC bits. Specifically, NR-PBCH uses 512-bit Polar codes to carry total 56 data bits. Different Polar code bit channels have different channel reliability. As a general rule, the most reliable Polar code bit channels are used for the 56 data bits. In accordance with a novel aspect, within the 32 NR-PBCH information bits, some of the information bits that can be known to the decoders under certain conditions and therefore are placed at the least reliable Polar code bit positions. As a result, by mapping the NR-PBCH data bits properly at the input bit positions of Polar codes, the NR-PBCH decoding performance is improved when the known bits a priori can be exploited.

  • Patent number: 10432234
    Abstract: Aspects of the disclosure provide polar code rate matching methods. A first method can include determining whether to puncture or shorten a mother polar code according to a mother code rate and/or a rate matched code rate, and selecting K positions in the sequence of N input bits for input of K information bits to a polar encoder according to an offline prepared index list ordered according to the reliabilities of respective synthesized channels. Frozen input bits caused by puncturing or shortening are skipped during the selection. A second method includes generating a mother polar code, rearranging code bits of the mother polar code to form a rearranged sequence that can be stored in a circular buffer, and performing, in a unified way, one of puncturing, shortening, or repetition on the rearranged sequence to obtain a rate matched code.
