Abstract: This application provides a method for federated learning. A communication apparatus triggers, by setting a threshold (a time threshold and/or a count threshold), fusion of a local model sent by a terminal device, to generate a global model, and when a fusion weight of the local model is designed, a data feature included in the local model of the terminal device, a lag degree, and a utilization degree of a data feature of a sample set of the corresponding terminal device are comprehensively considered, so that a problem of low training efficiency caused by a synchronization requirement for model uploading versions in a synchronous system can be avoided, and a problem of unstable convergence and a poor generalization capability caused by an “update upon reception” principle of an asynchronous system can be avoided.

Abstract: In an information sharing method, a communication apparatus obtains first information sharing level of a first device, and sends first shared information corresponding to the first information sharing level to a second device. The apparatus obtains a second information sharing level of the first device, and sends second shared information corresponding to the second information sharing level to the second device. The second information sharing level is different from the first information sharing level, the second shared information is not exactly the same as the first shared information, and the first shared information and the second shared information are for model training.

Abstract: When cell system information changes, a first terminal device receives, during on duration of the first terminal device, system information sent by a second terminal device, so that the first terminal device can receive the system information through a sidelink between the first terminal device and the second terminal device without a need to maintain a cellular link, thereby reducing complexity and power consumption of system information transmission. Alternatively, when cell system information changes and a first terminal device has only one receive radio frequency chain, the first terminal device obtains system information within a gap period of communication between the second terminal device and the first terminal device through a link between the first terminal device and a network device, so that the first terminal device maintains a cellular link only within the gap period, thereby reducing complexity and power consumption of system information transmission to some extent.

Abstract: This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.

The first information indicates that at least one default bandwidth part (BWP) corresponds to at least two active BWPs, the second information indicates that the at least two active BWPs correspond to at least one first timer, and the at least one first timer is useable by the terminal to perform deactivation processing on at least one of the at least two active BWPs. The method further includes performing, by the terminal, deactivation processing on the at least one of the at least two active BWPs, and activation processing on a BWP in the at least one default BWP based on the first and second information, or performing deactivation processing on the at least one of the at least two active BWPs based on the first and second information.
