Method and system for detecting and mitigating cabling issues with devices in substation automation systems
The invention relates to a method and system for detecting and mitigating cabling issues with devices connected in industrial redundant networks. An agent runs on each device and generates information about traffic received at the corresponding device. The agent running on a node generates indicators of traffic received at each port, and error rates for traffic at each port. The agent running on a switch generates information about switch misconfiguration by collecting device identifiers for each port of the switch. The agents send the information to a network manager, which determines switch misconfigurations and wrong cabling from the received information.

Equivalent puncture sets for polar coded re-transmissions
Wireless devices may use polar codes for encoding transmissions and may support combining transmissions to improve decoding reliability (e.g., by achieving chase combining and incremental redundancy (IR) gains). For example, an encoding device may puncture a set of mother code bits using different puncturing patterns to obtain different redundancy versions for a first transmission and a re-transmission. Each puncturing pattern may correspond to an equivalent decoding performance. In some cases, to obtain equivalent puncture sets, the encoding device may perform punctured index manipulation procedures on an initial puncturing pattern. A punctured index manipulation procedure may involve switching a binary state for a binary bit at a same binary bit index for each puncture index in a puncturing pattern. A device may receive the transmissions generated using the equivalent puncture sets and may combine the information for improved decoding reliability. |

Method and device in communication nodes for wireless communication with large propagation delay difference
A method and a device in communication nodes used for wireless communications. A communication node receives first information, transmits a first radio signal, and monitors a first-type signaling in a first time window. Wherein an end time for a transmission of the first radio signal is used for determining a start of the first time window, and a time-domain resource occupied by the first radio signal is used for determining a first characteristic identity. The first characteristic identity is one of M characteristic identities, M being a positive integer greater than 1, and the first information is used for determining the M characteristic identities. The first-type signaling carries one of the M characteristic identities, and the communication node determines a characteristic identity carried by the first-type signaling out of the M characteristic identities through blind detection. The random access performance is therefore improved. |
