Problems solved by technology

[0005]However, the QoS management mechanism in the NR V2X system is different from the QoS management mechanism in the LTE V2X system. For example, the LTE V2X system currently cannot recognize the QoS parameters such as QFI and / or 5QI
Therefore, if the QoS parameter management mechanism in the existing LTE V2X system can identify the QoS parameters in the NR V2X system, it is necessary to change the QoS parameter management mechanism in the LTE V2X system, which will increase the QoS parameters in the LTE V2X system. The complexity of the parameter management mechanism

Embodiment Construction

[0091] figure 1 A schematic diagram of a communication system architecture to which the embodiment of the present application is applicable is shown as an example. The communication system may include network equipment and communication devices. figure 1 The communication system includes one network device and two communication devices as an example. Such as figure 1 As shown, the communication system includes a network device 100 , a communication device 101 and a communication device 102 .

[0092]The network device 100 can communicate with the communication device 101 and the communication device 102 respectively in a wireless manner, for example, can communicate through a Uu air interface.

[0093] Communication between the communication device 101 and the communication device 102 can be performed in a wireless manner, for example, it can be transmitted through a sidelink (Sidelink, SL) air interface, and the SL air interface can also be called a wireless direct communi...

Abstract

The invention discloses a communication method and a communication device. The method comprises the following steps of determining a first wireless access technology for sending a first data packet, determining a first QoS parameter corresponding to the first data packet according to the first wireless access technology, and sending the first data packet to a second communication device through afirst wireless direct connection communication interface applying the first wireless access technology according to the first QoS parameter. The communication device has the capability of performing data transmission through a first wireless direct connection communication interface applying a first wireless access technology, and has the capability of performing data transmission through a secondwireless direct connection communication interface applying a second wireless access technology. Therefore, the first QoS parameter which can be identified by the first wireless direct connection communication interface can be determined as required without changing the existing mechanism for determining the QoS parameter.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular, to a communication method and a communication device. Background technique [0002] With the development of communication technology, a vehicle to everything (V2X) based on a cellular network is proposed in the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP). V2X is a new generation of information and communication technology that connects vehicles with everything. V stands for vehicles, and X stands for any object that interacts with the car, including cars, people, traffic roadside infrastructure and networks. Therefore, V2X interaction The information mode of the vehicle can include vehicle to vehicle (vehicle to vehicle, V2V), vehicle to pedestrian (vehicle to pedestrian, V2P), vehicle to infrastructure (vehicle to infrastructure, V2I) and vehicle to network (vehicle to network, V2N) interaction etc. [0003] In the long term ...
