  • Patent number: 11923930
    Abstract: A high-dimensional signal transmission method is provided. The method generates M M-dimensional first signals on the basis of M original signals and generates M M-dimensional second signals on the basis of a precoding signal and of the first signals, and finally, a transmitter sums all of the second signals and then transmits by utilizing M subchannels. As such, each subchannel carries information of the M original signals; hence, when any subchannel experiences deep fading, the deep fading is shared jointly by M signals, thus preventing the deep fading from causing a particularly severe impact on any signal. Moreover, all of the original signals can be recovered by utilizing the signals on the other subchannels, thus increasing the systematic resistance against subchannel deep fading. Meanwhile, the system implements the parallel transmission of the M original signals, thus ensuring the throughput of a communication system.

  • Patent number: 11893094
    Abstract: The invention discloses a DNN watermarking method, comprising embedding part of the digital watermark in selected redundant elements of a deep neural network (DNN) model—without compromising the performance of the DNN. The proposed method aims for a robust watermark scheme by embedding a large watermark that can span the whole DNN model. If an adversary attempts to destroy the watermark, the whole DNN model will be destroyed. However, maximizing the hiding capacity can lead to degradation in the performance of the DNN model. In this work, this capacity-performance trade-off problem is solved using the Discrete Cosine Transform (DCT). Moreover, the DCT can work more efficiently with highly correlated data. Therefore, this work suggests segmenting the weights of the DNN model into correlated segments to fully exploit the advantages of the DCT.

  • Patent number: 11864186
    Abstract: A wireless device receives configuration parameters indicating a linkage between a first search space (SS), of a scheduled cell, and a second SS, of a first bandwidth part (BWP) of a scheduling cell, and that a third SS, of the scheduled cell, is not linked to any SSs of a second BWP of the scheduling cell. In response to the linkage and the first BWP being active, the second SS is monitored for receiving a scheduling indication for the scheduled cell. The wireless device switches from the first BWP to the second BWP as an active BWP of the scheduling cell. In response to the switching and the third SS not being linked to the any SSs of the second BWP, the third SS is monitored for receiving DCI for the scheduled cell. The DCI is received via the third SS and for transmission on the scheduled cell.

  • Patent number: 11812421
    Abstract: Reliable communication in 5G and planned 6G networks depends on the fast, realtime decision-making regarding signal quality, beam parameters, and modulation. Rapid-fire messaging among hordes of diverse users in a busy urban setting will require efficient procedures for managing beam parameters in realtime, under complex changing conditions. The required time scales have already shrunk below the reflex time of humans. Therefore, artificial intelligence procedures are required for certain key aspects of feedback beam management. Disclosed are AI models for (a) instant evaluation of signal quality based on received signal properties and backgrounds, (b) incremental adjustment of beam parameters on demand, and (c) adapting the modulation scheme and size, based on fault patterns and QoS requirements. Each of these AI models can be tuned using network data, and then adapted for field use by a base station or a user device, for realtime beam parameter optimization.
