Abstract: A communications method and device for multi-carrier aggregation, where the method includes: grouping by a base station, N serving cells into K cell groups, where N is an integer greater than zero, and K is an integer less than N, sending, by the base station, a cell grouping message to user equipment (UE), where the cell grouping message indicates that the N serving cells are grouped into the K cell groups, and communicating, by the base station, with the UE according to the K cell groups. Hence, signaling overheads can be reduced.

Abstract: This application provides a measurement method, a terminal device, and an access network device. The measurement method includes: measuring, by a terminal device, signal quality of a plurality of beams, where the signal quality of the plurality of beams is obtained by using synchronization signal blocks; the signal quality of the plurality of beams includes signal quality of a same beam at different moments, and the plurality of beams belong to one cell; and obtaining, by the terminal device, signal quality of the cell based on the signal quality of the plurality of beams. In this way, cell measurement based on a synchronization signal is implemented, and the signal quality of the cell obtained based on the signal quality of the plurality of beams at the different moments is more accurate.

Abstract: The present invention discloses a carrier configuration method and a device, and relates to the field of communications, to resolve a problem that dividing multiple component carriers into primary and secondary component carriers only is not conducive to management of an important secondary component carrier. In a specific solution, a carrier aggregation model is configured for UE, so that the UE performs data transmission with a network device according to the carrier aggregation model. The carrier aggregation model includes multiple component carriers, the multiple component carriers include at least one core carrier, and the at least one core carrier includes at least one primary core carrier. The core carrier has an uplink transmission function and a downlink transmission function. The present invention is applied to a carrier configuration process.

Abstract: The present disclosure provides a communication method, a network-side device, and user equipment. The method includes: receiving, by a network-side device, a radio resource control RRC connection reestablishment request message, where the RRC connection reestablishment request message is used to request to perform RRC connection reestablishment; and sending, by the network-side device, an RRC connection reestablishment indication message, where the RRC connection reestablishment indication message carries a configuration parameter, and the configuration parameter includes at least one of a signaling radio bearer SRB2 configuration parameter or a data radio bearer DRB configuration parameter. The network-side device sends only the RRC connection reestablishment indication message, thereby effectively reducing a reestablishment delay and physical resource overheads.
