Abstract: Disclosed are methods for avoiding, detecting, and mitigating message faults. Due to the expected large increase in electromagnetic background energy in in dense 5G and 6G networks, message faults are likely to dramatically increase, along with their costs. To avoid intermittent interference, a user device can monitor the noise level and request that the base station store incoming messages while the noise level is too high. Likewise, if a user device receives a faulted message while the noise level is high, the user device can delay the retransmission until the noise subsides. If the user device has received two faulted messages (a likely scenario in crowded urban/industrial/sporting environments), the user device can merge the two versions while selecting the message elements with the best quality (based on modulation, SNR, stability, and other criteria) and may thereby obtain a corrected message version, without resorting to a third transmission of the message.

Abstract: Implantable medical devices (IMDs), and methods for use therewith, reduce how often an IMD accepts false messages. Such a method can include receiving a message and performing error detection and correction on the message. Such a method can also include determining a quality measure indicative of a quality of the message and/or a quality of a channel over which the message was received, and determining whether to reject the message based on the quality measure.

Abstract: A physiologic transmitter manages multiple communications between physiologic data acquisition devices attached to the patient and a receiver attached to an MRI or CT scanner. The transmitter's processor is able to generate waveform data and trigger data based upon the acquired physiologic data and transmit the data to a physiologic receiver attached to the host scanner. The receiver then is able to deliver a trigger signal to the host scanner for imaging the patient during a selected time frame based upon cardiac and/or respiratory cycles of the patient.

Abstract: Embodiments of an Evolved Node-B (eNB) and methods for HARQ transmission are disclosed herein. The eNB may transmit, to a reduced-latency User Equipment (UE), an initial HARQ block and a diversity HARQ block for a reduced-latency data block. A sub-frame spacing between the transmissions of the HARQ blocks may be less than a sub-frame spacing used for transmissions of HARQ blocks to UEs not operating as reduced-latency UEs. The HARQ blocks for the reduced-latency data block may be transmitted in a reduced-latency region of time and frequency resources reserved for HARQ processes with reduced-latency UEs. In addition, HARQ blocks may be transmitted in time and frequency resources exclusive of the reduced-latency region to other UEs not operating as reduced-latency UEs.

Abstract: A multimedia transceiver apparatus continuously generates a model of a video scene, and then uses the generated model to estimate missing sections (e.g., image frames) of the video stream by morphing and/or modifying available uncorrupted video data based on the model. By estimating the missing sections, the subjective quality of video under error conditions (e.g., image frame loss, image frame corruption, video signal interruption, etc.) is improved.

Abstract: A method and an apparatus for selectively performing packet error classification of multiple packet streams multiplexed to the same are provided. According to the method, generating an MMT packet can include: encapsulating an AU provided from a media codec layer to generate an MPU; and packetizing the generated MPU to generate the MMT packet. The MMT packet can include a packet header including a substream sequence number. Multiple substreams can be multiplexed and transmitted to a single port, and it is possible to detect, if a packet loss occurs, to which substream the lost packet belongs. Furthermore, based on this, an automatic repeat request (ARQ) can be made differently for each subframe and an error control policy can be taken differently for each subframe.
