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.

Abstract: A first terminal determines one or more sidelink resources. The one or more sidelink resources include at least a sidelink resource located in sidelink discontinuous reception-active time of a second terminal. The first terminal sends data to the second terminal on a first sidelink resource in the one or more sidelink resources. The first sidelink resource is located in the sidelink discontinuous reception-active time of the second terminal.

Abstract: A carrier configuration method and a related device are provided. A first carrier and a second carrier are configured for an electronic device, and the second carrier is a supplementary uplink carrier of the first carrier. The method includes: The electronic device receives a first message, where the first message includes configuration information of a secondary cell, and the secondary cell includes at least a serving cell corresponding to the second carrier. The electronic device configures, based on the configuration information of the secondary cell, the serving cell corresponding to the second carrier. That the serving cell corresponding to the second carrier is configured includes: An uplink of the second carrier remains as a supplementary uplink of the first carrier, or the supplementary uplink of the second carrier is deactivated, or an uplink of the second carrier is aggregated with an uplink of the first carrier.

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: A search space monitoring method allows a terminal to monitor a power saving signal in a search space in a scenario in which the power saving signal can be applied to a long discontinuous reception (DRX) cycle and a short DRX cycle. The method includes, when using the long DRX cycle, monitoring, by the terminal, the power saving signal in a first search space, and skipping monitoring the power saving signal in a second search space, where the power saving signal indicates power saving information of the terminal; and when using a short DRX cycle, monitoring, by the terminal, the power saving signal in the second search space, and skipping monitoring the power saving signal in the first search space.
