Abstract: The representative embodiments discussed in the present disclosure relate to techniques with which data packet loss, such as Transmission Control Protocol (TCP) packet loss, may be detected. More specifically, in some embodiments, by detecting a TCP packet with an enabled selective acknowledgement (SACK) signal, the loss (e.g., drop) of an additional TCP packet may be determined. Moreover, using information included in the detected TCP packet, an operational efficiency of a cloud computing system and/or a component of the cloud computing system may be determined.

Abstract: Message faults are inevitable in the high-throughput environment of 5G and planned 6G. Retransmissions are costly in time and resources, while generating extra backgrounds and interference. Therefore, methods are disclosed for recovering a faulted message by identifying and correcting each mis-demodulated message element. The faulted message elements generally have substantially lower modulation quality than the correctly demodulated elements, and can be identified by determining the modulation quality of each received message element. If the number of faulted message elements is small, the receiver may correct them using a grid search tested by an associated error-detection code. If the number of faults exceeds a predetermined threshold, the receiver can request a retransmission, and then assemble a merged copy of the message by selecting the message element with the best modulation quality from each version. Substantial time and resources may be saved, and reliable communication may be restored despite poor reception.

Abstract: A wireless telecommunications base station that compensates for Doppler shift in each connected User Equipment. The base station deploys a plurality of parallel receivers, each with a given frequency offset above and below the carrier frequency. Each receiver performs a frequency shift on a common uplink signal, determines the quality of the frequency shifted uplink signal, and demodulates the frequency shifted uplink signal. A selector/combiner module generates a highest quality demodulated signal, which may be done by selecting the frequency shifted uplink signal or soft combining a subset of frequency shifted uplink signals having a sufficiently high quality.

Abstract: The technologies described herein are generally directed to changing error mitigation protocols used for a connection based on the quality of a network connection in a fifth generation (5G) network or other next generation networks. For example, a method described herein can include determining, by network equipment comprising a processor, that a quality of a connection between a user equipment and a network access point is below a connection quality threshold, with the connection employing a communications protocol using a first error mitigation process, and where the network access point enables respective access to services enabled via a communication network. The method can further include, based on the quality and the first error mitigation process, enabling, by the network equipment, a second error mitigation process of the communications protocol of the connection, the second error mitigation process being different than the first error mitigation process.

Abstract: A central challenge in next-generation 5G/6G networks is achieving high message reliability despite very dense usage and unavoidable signal fading at high frequencies. To provide enhanced fault detection, localization, and mitigation, the disclosed procedures can enable an AI model (or an algorithm derived from it) to discriminate between faulted and unfaulted message elements according to signal quality, modulation parameters, and other inputs. The AI model can estimate the likelihood that each message element is faulted, and predict the most probable corrected value, among other outputs. The AI model can also consider the quality of a demodulation reference used to demodulate the message, and the quality of the associated error-detection code. The AI model can also consider previously received messages to the same receiver, or messages of a similar type. Fault mitigation by the receiver can save substantial time and resources by avoiding a retransmission. Many other aspects are disclosed.

Abstract: Apparatus and methods concerning simulation of call quality are disclosed. In an example embodiment, computing server is communicatively coupled to a server. The computing server is configured to receive a first set of data which may include audio of a call routed by the server. The computing server also includes a processing circuit configured to characterize a post-transmission quality state of the first set of data. The processing circuit is also configured to generate a second set of data including audio that is different from the audio of the call and data including characteristics indicative of the post-transmission quality state of a first set of data. The processing circuitry may configured to use the second set of data to provide security, protect the confidentiality and privacy, and/or monitor changes of behavior/quality for different audio CODECs, encryption, bit-rate, etc.
