Problems solved by technology

In the new air interface (new radio, NR) technology, if you want to realize unicast transmission between two terminal devices and perform unicast communication according to the D2D mechanism, the data corresponding to different V2X services need to multiplex the same set of logical channels, that is, The data corresponding to different V2X services may be multiplexed into one media access control (media access control, MAC) layer protocol data unit (protocol data unit, PDU) for transmission, causing the receiving end terminal device to be unable to identify different V2X services

Abstract

The present application provides a method and a communication device for unicast transmission. The method includes: a first terminal device generates first data; the first terminal device sends the first data, information of a destination identifier, and a second terminal device to the second terminal device. The information of the target service identifier, wherein the information of the target identifier is used to identify the second terminal device, the information of the target service identifier is used to identify the IoV V2X service corresponding to the first data, and at least one service corresponding to the target identifier The identity includes the target business identity. In the present application, by sending the first data, the information of the destination identifier and the information of the target service identifier, unicast transmission of data of different services / different service types can be realized between two terminal devices.

Description

technical field [0001] The present application relates to the field of communication, and more particularly, to a method and communication device for unicast transmission. Background technique [0002] Vehicle to everything (V2X) is considered to be one of the fields with the most industrial potential and the clearest market demand in the IoT system. It has the characteristics of wide application space, great industrial potential and strong social benefits. It is of great significance to innovate and develop the communication industry, build new models and formats of automobiles and transportation services, promote the innovation and application of autonomous driving technology, and improve traffic efficiency and safety. [0003] In a device to device (D2D) communication system, the sending end device can initiate the process of establishing a direct communication unicast connection. After the two terminal devices establish a unicast connection in D2D, all services can be co...
