Abstract: Methods, systems, and devices for wireless communications are described. A first device may receive one or more signals from a second device. The first device may estimate one or more metrics associated with noise of the one or more signals. The first device may transmit, to the second device and based on the estimating, a report indicating the one or more metrics. The first device may receive a message indicating a multi-level coding scheme from the second device. The multi-level coding scheme may be based on the one or more metrics and may indicate a partitioning configuration of the multi-level coding scheme for communications between the first device and the second device. The first device may communicate with the second device using the partitioning configuration of the multi-level coding scheme.

Abstract: Systems and methods are provided for edge-based loss-of-signal (LOS) detection. In a receiver, a receiver port receives a data signal. A clock and data recovery (CDR) mechanism coupled to the receive port derives one or more clock signals. An LOS signal generation mechanism generates an LOS signal based on edge glitches which occur when the receive port does not receive usable data.

Abstract: A data transmission method capable of suppressing communication errors with a simple microcomputer processing is provided. Upon a pulse signal in which specific data is made up of H and L levels, either one of which has a pulse width taken as a first fundamental signal length T1 and the other of which has a pulse width taken as a second fundamental signal length T2 equal to an integer multiple of the first fundamental signal length T1, a correction is performed by increasing or decreasing the second fundamental signal length T2 by a length equal to an integer multiple of a value resulting from dividing the first fundamental signal length T1 of the transmission-side pulse signal by an integer.

Abstract: A communication apparatus according to the present invention detects the trailing edge of the received data and, with the detection of the trailing edge the apparatus, acknowledges the reception of the start bit in the received data. The bit level of the start bit is monitored to examine whether or not the bit level is at a predetermined bit level. If any change is detected, a signal indicating occurrence of a start-bit-detection error is output to the outside.

Abstract: In a data receiver, pulse edges are sequentially detected from the pulse string. If a pulse which has a width equal to two cycles of the reference clock signals is detected, bit data null1null is restored. If two consecutive pulses each of which has a width equal to one cycle are detected, bit data null0null is restored. If a pulse width between two consecutive pulse edges is not equal to one cycle or two cycles, it is presumed that a pulse edge of an erroneous pulse is detected. If the pulse width between the pulse edge, which is presumed to correspond to the erroneous pulse, and the next pulse edge is equal to or shorter than a predetermined threshold Th, the pulse edge and the next pulse edge is invalidated.

Abstract: An abnormality detection device detects an abnormality in a communication bus. The abnormality detection device comprises a timer counter connected to the communication bus so as to measure a time during which a signal having a first logical level is transmitted in the communication bus, and a comparator outputting an abnormality detection signal indicating an abnormality in the communication bus when the time measured by the timer counter surpasses a threshold value.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of a multi-level coding (MLC) capability for uplink transmissions. The UE may receive a configuration of a selected MLC scheme associated with an uplink transmission, wherein the configuration of the selected MLC scheme is based at least in part on the indication of the MLC capability for the uplink transmissions. Numerous other aspects are described.
