Abstract: A feedback method is provided, including receiving, by a first device, data sent by a second device, and sending, by the first device to the second device, feedback information indicating whether the data is successfully received. In this method, a quantity of bits of the feedback information is associated with a size of a transmission time unit in a communications system. By using the foregoing method, the quantity of bits of the feedback information is determined based on the size of the transmission time unit. This implements a compromise between transmission efficiency and feedback overheads in the communications system.

Abstract: A signal scrambling method and apparatus, and a signal descrambling method and apparatus are disclosed. In the signal scrambling method, a communications apparatus scrambles a signal by using a scrambling sequence, and sends the scrambled signal. In the signal descrambling method, a communications apparatus receives a signal, and descrambles the signal by using a scrambling sequence. An initial value of the scrambling sequence is determined based on a time unit number corresponding to a frame structure parameter used for transmitting the signal, so that different scrambling sequences can be used to scramble signals that are transmitted by using different frame structure parameters. Therefore, interference randomization can be implemented for signal scrambling, and this can be applicable to various application scenarios in 5G NR to improve performance.

Abstract: Data heterogeneity has been shown to reduce the convergence speed and model accuracy in existing federated learning (FL) and distributed learning (DL) based artificial intelligence or machine learning (AI/ML) model training processes. In some embodiments, a group of devices participating in an FL or DL based AI/ML model training process is divided into clusters, e.g., based on similarities in their data class distributions, and each device is configured with a cascaded AI/ML model that includes a first AI/ML sub-model and a second AI/ML sub-model that are cascaded. For each device, one of the cascaded sub-models is a common AI/ML sub-model that is common to all devices in the group, and the other sub-model is a cluster-specific AI/ML sub-model that is common to the cluster that the device has been assigned to within the group of devices. A multi-stage training process for the cascaded AI/ML model is also provided.

Abstract: Example wireless communication methods and apparatus are described. In one example method, a relay device receives a first signal sent by a first device, where the first signal carries a plurality of bits. The relay device decodes the first signal to determine first information corresponding to each of a plurality of first bits. The first information corresponding to each first bit is determined based on a probability that the first bit is 1 and a probability that the first bit is 0. The relay device sends the first information in a second signal to a second device, so that the second device can use the first information to decode the first signal.

Abstract: Methods and devices are provided for HARQ feedback and retransmission schemes for a two stage DCI transmission scenario. A first HARQ-ACK may be used for the 2nd stage DCI and a second HARQ-ACK may be used for other PDSCH scheduled by the 2nd stage DCI. Dedicated fields may be used in a 1st stage DCI of the two stage DCI scenario for providing update information for PDSCH HARQ feedback timing when the 2nd stage DCI is retransmitted.
