摘要： The present disclosure provides a method and apparatus for generating equivalent nonlinear noise. The method includes randomly generating white noise obeying zero-mean Chi-square distribution; and filtering the input white noise by using an equivalent nonlinear noise spectrum as an equivalent nonlinear filter to obtain the equivalent nonlinear noise. According to the embodiments of the present application, equivalent nonlinear noise may be generated based on zero-mean Chi-square distribution random variables combined with equivalent nonlinear noise spectrum filtering, and more accurate equivalent nonlinear noise than the related art may be generated, thus accurately evaluating an influence of nonlinearity of devices on Bit Error Rate (BER).

摘要： Message faulting is an increasing problem in 5G and future 6G due to network crowding, receiver motion, signal fading at higher frequencies, and greater phase-noise sensitivity. Disclosed herein are methods for analyzing waveform features of the received signal using artificial intelligence, and identifying the likely faulted message elements according to correlations of those waveform features. For example, after demodulating, the receiver can identify a subset of message elements that are all demodulated according to the same modulation level, and can measure a signal parameter for each message element in the subset. The processor can then average the deviations in the subset, and compare those message elements to the average for the subset. If one of the message elements shows an anomalously large deviation from the average, that message element is likely faulted.

摘要： Wireless communication techniques that include PTRS resource density recommendation and selection techniques are discussed. A UE may transmit to a base station a set of phase tracking reference signal (PTRS) resource density recommendations that are determined based, at least in part, on a block error rate (BLER). The base station may transmit to the UE an indication of PTRS resource densities to use for wireless communication of the PTRS based, at least in part, on the BLER associated with the received set of PTRS resource density recommendations. The base station and/or the UE may at least one of receive or transmit a PTRS based, at least in part, on the indicated PTRS resource densities. Other aspects and features are also claimed and described.

摘要： A method for equalizing a wireless communication channel includes transmitting a data signal over a primary channel. During transmission of the data signal, a corresponding data signal is sent over a secondary channel. The information received from the secondary channel is compared to the information received from the primary channel and differences between the information received from each of the channels are observed. These differences are used as inputs to an equalizer algorithm that may be used to reduce distortion of the data signal sent over the primary channel.

摘要： Beam failure recovery (BFR) in a multiple Downlink Control Information (mDCI) mode may include receiving, by a user equipment (UE), a Downlink Reference Signal (DL RS) set from a next generation Node B (gNB). The DL RS set may be associated with a link between the UE and the gNB and indicate beam failure detection (BFD) is to be performed for the link. The BFR may further include performing, by the UE, a beam failure detection (BFD) for the link using the DL RS set, and performing, by the UE, a candidate beam detection (CBD) for the link, the CBD determining a candidate beam for the link by determining a beam having a reference signal receiving power (RSRP) that is larger than an RSRP threshold. The BFR may further include transmitting, by the UE, a beam failure recovery request (BFRQ) indicating the link to the gNB.

摘要： A data transmission method is provided. The data transmission method may be applied to a multi-link operation between a first multi-link device (MLD) and a second MLD. The data transmission method may include the following steps. A processor of the first MLD may perform a spatial reuse transmission on at least one link between the first MLD and the second MLD. Then, the processor may dispatch data frames with the same traffic identifier (TID) for all links between the first MLD and the second MLD based on the physical layer (PHY) rates and packet error rates of all links between the first MLD and the second MLD. Then, the processor may transmit the data frames to the second MLD based on the dispatch result.

摘要： One embodiment provides a method and a system for computing diagnoses for a physical system. During operation, the system can obtain a design of the physical system, generate a design of a diagnostic system by augmenting the design of the physical system based on a number of fault-emulating subsystems, and convert the design of the diagnostic system into a polynomial formula comprising a plurality of variables. The plurality of variables can include inputs and outputs of the original physical system and a number of ancillary variables. The system can further embed the polynomial formula on a hardware-based solver configured to perform optimization using the polynomial formula as an objective function to obtain a diagnostic vector used for explaining faults in the physical system.

摘要： Technologies for optimizing post-FEC bit error rate performance of a Forward Error Correction (FEC) system are described. A controller is coupled to an FEC circuit and a receiver circuit. The controller receives FEC symbol error data from the receiver circuit and determines, using the FEC symbol error data, a post-FEC correlated performance metric indicative of an estimated post-FEC BER of the FEC circuit. The controller adjusts, based on the post-FEC correlated performance metric, at least one of a FEC parameter of the FEC circuit or a link parameter of the receiver circuit to decrease the estimated post-FEC BER. This improves the post-FEC BER performance of the FEC circuit.
