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.

The method includes: generating, by a first base station, downlink radio link control (RLC) protocol data units (PDUs); and sending, by the first base station, a first part of downlink RLC PDUs in the downlink RLC PDUs to a user equipment UE, and sending a second part of downlink RLC PDUs in the downlink RLC PDUs to a second base station, so that the second base station sends the second part of downlink RLC PDUs to the UE. Hence, the first base station and the second base station are capable of jointly sending data to the UE, thereby improving a peak rate and a throughput of the UE.

Abstract: Example methods for processing a system message and network devices are described herein. One example method includes obtaining, by a user terminal, indication information, wherein the indication information indicates that a system message of a cell cluster has changed or whether a system message of a cell cluster has changed, wherein the cell cluster comprises a set of at least one cell. The user terminal can then determine whether currently used information about the cell cluster needs to be updated. In some instances, obtaining the indication information comprises obtaining a system information update message. In those instances, determining whether currently used information about the cell cluster needs to be updated can include updating the currently used information about the cell cluster or updating a system message of a cell in the currently used cell cluster based on the indication information in the system information update message.

Abstract: Embodiments of the present invention provide a paging message sending method, a paging message receiving method, and a device. A base station sends, to UE, configuration information of a first paging resource reserved by a core network for the UE. When the base station performs paging area paging on the UE, the base station sends, on the first paging resource, a first paging message to the UE. In the embodiments, all multiple cells included in a paging area use the first paging resource to perform paging area paging, and all the multiple cells use same paging scrambling code to scramble the first paging message when sending the first paging message.
