Abstract: Embodiments of the present invention provide a base station, a terminal device, and a communication system for inter-base station carrier aggregation. A primary base station of the terminal sends a message including indication information to request the terminal device to report a timing offset between the primary base station and a secondary base station of the UE. The secondary base station calculates a corrected measurement gap information according to a measurement gap information and the timing offset. In a second measurement gap period indicated by the corrected measurement gap information, the terminal device is not scheduled.

Abstract: Embodiments of the present invention provide a base station, user equipment, and a measurement method for inter-base station carrier aggregation. The method includes: a primary base station of the UE sends a message include indication information to request the UE report a timing offset between the primary base station and a secondary base station of the UE; the secondary base station calculates a corrected measurement gap information according to a measurement gap information and the timing offset; the secondary base station stops scheduling the UE in a measurement gap period indicated by the corrected measurement gap information. In the embodiments of the present invention, the secondary base station does not schedule user equipment in a measurement gap period of the UE, which avoids waste of an air interface resource and improves the network transmission efficiency.

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.
