Embodiment Construction

[0039] The present application provides a data transmission method and device, which are used to reduce the uplink data transmission delay of the DRB when a terminal configured with dual connectivity performs the above data transmission on the DRB. Wherein, the method and the device are based on the same inventive concept. Since the method and the device have similar problem-solving principles, the implementation of the device and the method can be referred to each other, and the repetition will not be repeated.

[0040] Part of the terms used in the embodiments of the present application are explained below to facilitate the understanding of those skilled in the art.

[0041] 1) Terminal, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device that provides voice and / or data connectivity to users device of. For example, the terminal device includes a handheld device with a wireless connection function, a vehicle-mounted device, and the...

Abstract

The present application relates to the field of communication technology, and discloses a data transmission method and device for reducing the uplink data transmission delay of DRB. The method is: the terminal performs uplink data transmission on the DRB, wherein the DRB is a first bearer type, and the PDCP entity of the first bearer type is configured to associate an RLC entity corresponding to the first cell group with a corresponding second cell The RLC entity of the group, the first cell group belongs to the first network device, and the second cell group belongs to the second network device; when the terminal determines that the accessed second cell group is unavailable, the DRB type The first bearer type is converted to the second bearer type, and the PDCP entity of the second bearer type is only associated with the RLC entity corresponding to the first cell group.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a data transmission method and device. Background technique [0002] With the continuous development and improvement of 5G new radio (new radio, NR), NR has gradually moved towards commercial use. In order to ensure the stability of data transmission, in the initial stage of NR deployment, the networking mode of dual connectivity (DC) will be It is the networking mode chosen by most operators. The dual-connection networking modes that exist in 5G applications include: (1) ED-DC networking mode, that is, the terminal is connected to the 4G LTE base station and the 5G NR base station at the same time. In the EN-DC networking mode, the NR base station It is called En-gNB, and the LTE base station is called eNB. Among them, the LTE base station is the main base station / node, also called MeNB in ​​EN-DC, and the NR base station is the seconda...
