Retransmission of selected PAM-modulated message portions in 5G/6G
11456821 · 2022-09-27 · ·

When a received message is found to be corrupted in 5G or 6G, the receiver can request a retransmission. If only one message element is faulted, retransmitting the whole message may be a waste. Procedures are disclosed for the receiver to determine which message elements are likely faulted by measuring the modulation quality and optionally other signal quality factors. The receiver can then indicate, in an acknowledgement for example, which portion of the message needs to be retransmitted. After receiving that retransmitted portion, the receiver can then produce a merged version by substituting the retransmitted portion into the as-received message. Alternatively, the receiver can select the best-quality elements from the two versions for the merged copy, and thereby eliminate most or all of the faults. Networks supporting these protocols may have fewer delays, faster responses, improved reliability, and reduced resource usage by avoiding unnecessary retransmission volumes.

QUALITY OF EXPERIENCE OPTIMIZATION SYSTEM AND METHOD

A Quality of Experience (QoE) optimization system and method are provided. An electronic device inputs key performance indicators (KPIs) and system control parameters collected from a core network, a base station and a user equipment (UE) into a QoE optimization model. The QoE optimization model then optimizes the system control parameters based on the KPIs and a user QoE fed back from the UE to output optimized system control parameters. Furthermore, a strategy emulator controls at least one of a base station emulator and a UE emulator, so as to emulate the QoE optimization model using the at least one of the base station emulator and the UE emulator. Non-real-time optimization adjustments to the QoE optimization model are made based on the result of the emulation performed by the at least one of the base station emulator and the UE emulator.

Error Detection and Correction in 5G/6G Pulse-Amplitude Modulation
20220173830 · 2022-06-02 ·

Message failures due to noise and interference cause unnecessary delays and reduction in reliability in wireless networks. To detect, localize, and correct transmission faults in 5G and 6G networks, the receiver can measure the “modulation quality” of each message resource element modulated in PAM (pulse-amplitude modulation), according to how closely the amplitudes of the in-phase and quad-phase signal branches match the amplitude levels of the modulation scheme. If the message is faulted, the receiver can re-assign each message element with poor modulation quality to the adjacent states, or if necessary to each state in the modulation scheme, and may thereby find the correct message value in many cases. When implemented, message fault mitigation as disclosed herein can resolve message failures, improve communication reliability, reduce latency, and improve network operations overall, according to some embodiments.

Method and network node, for handling link adaption of a channel

A method performed by a network node, for handling link adaption (LA) of a channel. The network node obtains a channel quality value for each Transmission Time Interval (TTI) in a set of TTIs. The network node estimates a probability that a specific channel quality will occur from the obtained channel quality values for the set of TTIs based on a distribution of channel quality values. The network node further determines a set of transmission parameters which optimizes a target function of LA, based on the estimated probability for the channel quality, wherein each set of transmission parameters is mapped to a channel quality which is required for a successful reception.

Systems and methods for profile management driven operations
