Abstract: Embodiments of this application provide a paging method, a device, and a storage medium. The method includes: A core network device obtains time information of a paging moment at which a first network device pages a terminal device, and sends first message to the first network device based on the time information of the paging moment at which the first network device pages the terminal device, wherein the first message is used to page the terminal device. In the embodiments of this application, paging moments for paging the terminal device in various cells are dispersed. In this way, after the terminal device accesses a cell, the terminal device is no longer paged in another cell in which paging of the terminal device is not started. Therefore, paging overheads of paging the terminal device can be reduced in a paging area.

Abstract: A communication method and an apparatus are provided. The method includes: receiving, by a terminal device, a first command sent by a network device, wherein the first command carries a first identifier, and is used to activate a first bandwidth part (BWP) indicated by the first identifier, and the first BWP is a BWP on a first component carrier (CC); and ignoring the first command when the terminal device does not support the first BWP and a second BWP being in an active state at the same time, wherein the second BWP is a BWP in the active state on a second CC, and the second CC is different from the first CC. According to the application, the terminal device may determine, based on a capability of the terminal device, to ignore an improper command, to optimize a problem of switching an active BWP in a carrier aggregation scenario.

Abstract: A data processing method by a data sending apparatus is described. The method includes receiving a data packet from a PDCP layer, where the data packet is used as an RLC SDU. The method further includes encapsulating the RLC SDU into at least one RLC PDU, where each RLC PDU includes a header and a payload. The payload carries data from a single RLC SDU. It can be learned that a transmit end no longer performs concatenation processing at the RLC layer on the data packet. In this way, concatenation processing at the transmit end is reduced, and processing complexity and processing latency are further reduced. In addition, processing at a receive end also becomes simpler and more efficient.
