Problems solved by technology

[0003] For dual connectivity / multi-connection of different systems, different base stations serving UE may have different capabilities, and the channel coverage of a certain base station may be limited, which will cause some necessary uplink information to be unable to be sent directly from the UE to the UE that should be received. A base station for these information, such as a secondary node, will cause problems such as failure to add a secondary node, or failure to transmit after subsequent connection establishment

Embodiment Construction

[0044] Before the method for determining the uplink information transmission path of the embodiment of the present invention is described in detail, the application architecture of the embodiment of the present invention is briefly described first.

[0045] During the deployment of the fifth-generation mobile communication system (5G) network, the 5G cell can be used as a macro coverage independent network, or as a small cell to provide coverage and capacity for the existing Long Term Evolution (LTE, Long Term Evolution) network. enhanced. No matter which networking method is adopted, dual connectivity technology can be used to realize the interconnection between LTE system and 5G system, thereby improving the utilization rate of wireless resources of the entire mobile network system, reducing the delay of system switching, and improving user and system performance. The embodiment of the present invention is applicable to a dual-connection application scenario in which a termi...

Abstract

The embodiment of the invention discloses a method and a terminal for determining an uplink information transmission path. The method includes: the terminal judges whether the trigger condition is satisfied; when the trigger condition is judged to be satisfied, switching the transmission path of the uplink transmission information from the first link corresponding to the first node to the second link corresponding to the second node and sending the uplink transmission information to the second node through the second link, so that the second node forwards the uplink transmission information to the first node.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for determining an uplink information transmission path and a terminal. Background technique [0002] Evolved Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) Terrestrial Radio Access (E-UTRA, Evolved-UMTS Terrestrial Radio Access)-New Radio (NR, New Radio) Dual-Connectivity (DC, Dual-Connectivity) (referred to as EN-DC), the user equipment (UE, UserEquipment) first establishes a connection with the master node, and then initiates random access to the slave node during the process of adding the slave node. Uplink and downlink messages are transmitted on the link. [0003] For dual connectivity / multi-connection of different systems, different base stations serving UE may have different capabilities, and the channel coverage of a certain base station may be limited, which will cause some necessary uplink ...
