COMMUNICATION METHOD, AND TERMINAL

摘要

Embodiments of the present disclosure disclose a data retransmission communication method and a terminal for implementing inter-base station carrier aggregation, where the method includes: receiving, by a first Radio Link Control (RLC) entity of a terminal, a packet data unit PDU; and when the first RLC entity determines that the PDU reaches a maximum quantity of retransmissions, instructing, by the first RLC entity, a second RLC entity of the terminal to transmit the PDU, where the first RLC entity is corresponding to a first base station, and the second RLC entity is corresponding to a second base station. By using the method and the terminal in the embodiments, frequency of RRC connection re-establishment is reduced, and a data packet loss caused by frequent re-establishment is further avoided, thereby improving user experience.

主权项

1. A communication method, comprising:
detecting, by a terminal, that a quantity of retransmission of a first Radio Link Control (RLC) entity reaches a maximum value, wherein the terminal includes the first RLC entity; initiating, by the terminal, a RRC connection re-establishment when all serving cells aggregated for the terminal belong to one base station; and not initiating, by the terminal, a RRC connection re-establishment when serving cells aggregated for the terminal belong to different base stations and the first RLC entity corresponds to a secondary base station, wherein the different base station comprises a primary base station and the secondary base station.
