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: 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.

Abstract: Embodiments of the present invention disclose a random access method and an apparatus. According to the random access method disclosed in the embodiments, first downlink assignment information is obtained in a manner of a mapping relationship between first downlink assignment information and a preamble, where the first downlink assignment information is downlink assignment information used by a random access response message, and scheduling signaling of the random access response message does not need to be retransmitted by using the PDCCH channel, thereby resolving problems of a channel resource waste and an access delay in an existing random access method. The problems are caused because the PDCCH channel is used to retransmit the scheduling signaling of the random access response message.

Abstract: Embodiments provide a communication method, terminal, and a base station. The method includes: receiving, by terminal, a reference signal sent by a base station; and obtaining, by the terminal, channel energy of a narrow beam by measuring the reference signal, where the narrow beam is a directional beam. According to the communication method in the embodiments of the present disclosure, the terminal may obtain the channel energy of the narrow beam by measuring the reference signal. Compared with the prior art in which channel energy of a narrow beam is measured on a base station side, a difference is that the terminal can more accurately estimate the channel energy of the narrow beam. That is, the channel energy of the narrow beam estimated by the terminal can more accurately reflect channel quality, and transmission efficiency can be improved.
