Abstract: A data packet, that is to be transmitted in a dual connectivity (DC) or carrier aggregation (CA) based communications system, may include an indication to indicate whether the data packet is configured to be transmitted in a first frequency of a first carrier or a second frequency of a second carrier, and be transmitted, by a communication device, in the first frequency or the second frequency based on the indication. A data packet in the communications system may also be transmitted first in a first frequency higher than a second frequency, and then be retransmitted in the second frequency upon transmission failure of the data packet in the first frequency.

Abstract: A data processing method and a terminal device and a base station. The method includes: the terminal device determines to change the type of at least one wireless carrier of the terminal device from a first type to a second type and discards a radio link control protocol RLC and/or an RLC service data unit buffered by a transmit side of an RLC entity of at least one radio bearer. The terminal device assembles an RLC protocol data unit received by a receive side of the RLC layer entity of at least one radio bearer into an RLC service data unit, and delivers the RLC service data unit to an upper layer entity of the RLC layer entity, where the upper layer entity is an upper layer entity of the RLC layer entity before the type of the at least on radio bearer is changed.

Abstract: A route update method relating to a communications field includes: sending a medium access control protocol data unit (MAC PDU), wherein the MAC PDU comprises a first buffer status report (BSR); and canceling, in response to the sending of the MAC PDU, a scheduling request triggered prior to the MAC PDU assembly. The first BSR comprises a buffer status up to the last event that triggers a BSR prior to the MAC PDU assembly.

Abstract: Embodiments of this application provide a path switching method and a related device. The method includes: receiving, by a base station, a first message sent by first user equipment, where the first message is used to request to switch the first user equipment from a non-direct path for communicating with the base station by using second user equipment to a direct path communicating with the base station; and sending, by the base station, a second message to the first user equipment, where the second message is used to instruct the first user equipment to perform path switching, and the second message includes at least one of a timing advance, a closed-loop power control value, and an uplink grant configuration. Therefore, service continuity in a path switching process is maintained, and service quality is improved.

Abstract: Example handover methods and devices in an ultra-dense network are disclosed. One example method includes the following operations. A source base station sends a first message to a target base station, where the first message carries an arrival time indication of a terminal, and the arrival time indication is used to indicate a time at which or a time range in which the terminal is to access the target base station. The source base station receives a second message fed back by the target base station, where the second message carries a granted resource that is allocated for the arrival time indication of the terminal. The source base station adds the granted resource to a command message, and sends the command message to the terminal.

Abstract: A device-to-device (D2D) communication method and a D2D terminal device, where the method includes determining, by a first device, a time that the first device is out of coverage of a synchronization source after leaving the coverage of the synchronization source determining, by the first device, target timing based on the time, and performing, by the first device, D2D communication based on the target timing. Hence, the target timing can be selected more accurately for the first device.
