Abstract

The embodiment of the invention provides a communication method and a communication device. The method comprises the following steps: a first terminal device receives first information sent by a second terminal device, wherein the first information comprises data information or indication information related to the data information; the first terminal device determines a first time-frequency resource according to the first information, and then sends feedback information of data information to the second terminal device on the first time-frequency resource. The method is used for realizing anend-to-end communication scene, a terminal device of a receiving end can provide feedback of the data information sent by a terminal device of a sending end, and the reliability of communication is improved.

Description

technical field [0001] The present application relates to the field of information technology, and in particular, to a communication method and a communication device. Background technique [0002] With the evolution of communication technology, the Internet of Everything technology is also accelerating development. The 3GPP standard specifications have introduced multiple Internet of Everything technologies, such as NB-IOT technology, MTC / (e)MT technology, etc., which are all Internet of Things technologies. In addition, 3GPP standard specifications also introduce IoT and end-to-end technologies, such as D2D and V2X. [0003] Currently in LTE, the sidelink (secondary link) communication technology only defines a broadcast service mode, that is, a UE sends signals to other devices in a broadcast form. In NR, the sidelink communication technology introduces a unicast service mode. If the receiving end does not give feedback to the data sent by the sending end, mistransmissio...
