Problems solved by technology

In this case, if the transmitting UE and the receiving UE still independently establish and configure radio bearers, the radio bearer configuration used by the receiving UE when receiving data and the radio bearer used by the transmitting UE when sending the data will be different. The configuration does not match or is inconsistent, which will cause the receiving UE to fail to process the received data correctly, or fail to guarantee the QoS requirements of the V2X service

Abstract

The invention provides a radio bearer configuration method, a terminal and a communication device. The method comprises the following steps: a first terminal device sends a first message to a second terminal device, wherein the first message is used for indicating the second terminal device to configure or reconfigure a first sidelink radio bearer with the first terminal device; the first terminaldevice receives a second message sent by the second terminal device, wherein the second message is used for indicating the second terminal device to complete configuration or reconfiguration of the first sidelink radio bearer, or the second message comprises configuration information of the first sidelink radio bearer. According to the method disclosed in the technical solution, that the radio bearer configuration adopted by the receiving end terminal device during data receiving is consistent with the radio bearer configuration used by the sending end terminal device during data sending canbe ensured, and therefore the receiving end terminal device can correctly process the received data.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and more specifically, to a radio bearer configuration method, a terminal, and a communication device. Background technique [0002] In a wireless network, a base station and a terminal device can communicate through an uplink (uplink) and a downlink (downlink). Terminals may use a sidelink (sidelink) to communicate with each other. [0003] In the long term evolution (longtermevolution, LET) vehicle to outside information exchange (vehicle to everything, V2X) system, only broadcast services are supported. The radio bearer of the sidelink (sidelink) is established and configured by the sending UE and the receiving UE respectively, and the sending UE and the receiving UE do not need to coordinate the configuration of the radio bearer. [0004] In the fifth generation (5G) mobile communication technology (fifth generation, 5G) V2X system, when terminals and terminal devices c...
