Abstract: An uplink synchronization processing method, a User Equipment (UE), and a base station are provided. The method includes: receiving a component carrier (CC) uplink synchronization indication message sent by a base station, where the uplink synchronization indication message carries identification information of one or multiple newly configured CCs; sending synchronization signaling to the base station when determining that the uplink synchronization needs to be executed on all or a part of the one or multiple newly configured CCs corresponding to the identification information; and receiving a time advanced (TA) adjusting message that is sent by the base station according to the synchronization signaling, and applying a TA value carried in the TA adjusting message to the CC on which the uplink synchronization needs to be executed.

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: A mobility management method, user equipment, and a network device are provided. The mobility management method includes: receiving, by user equipment UE in a connected state, a handover-free UE identifier from a network device, where the handover-free UE identifier is used to uniquely identify the UE in a handover-free state in a handover-free area, and the handover-free area includes at least two cells; entering, by the UE, the handover-free state after meeting an activation condition, where in the handover-free state, the UE stores the handover-free UE identifier and a connection context that is of the UE in the connected state, and the UE does not execute a handover procedure when the UE moves in the handover-free area; sending, by the UE, the handover-free UE identifier to the network device after the UE determines that a deactivation condition is met.

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 of the present invention provide an information transmission method, a device, and a system. The method includes: determining, by UE, a type of a coverage area in which the UE is located, where the type of the coverage area is a first coverage area or a second coverage area; and receiving, by the UE by using a corresponding beam according to the type of the coverage area in which the UE is located, the broadcast information sent by the network device. Therefore, when the UE is covered in the different coverage areas, the broadcast information sent by the network device can be received, and this ensures normal communication between the UE and the network device.
