Abstract

The invention discloses a V2X unicast communication method, a terminal device and system. Communication is realized between a sending terminal and a receiving terminal, and the method comprises the following steps: the sending terminal sending indication information at a first resource position to indicate that a pilot signal exists; transmitting a pilot signal at a second resource location; the receiving terminal receiving the pilot signal according to the indication information, measuring the pilot signal, generating channel state information and sending the channel state information at a fourth resource position; the receiving terminal sending scheduling information at a third resource position to indicate a fourth resource position; and the sending terminal receiving the channel stateinformation according to the scheduling information and determining a modulation and coding scheme. The invention also discloses a mobile terminal which is used as a sending terminal or a receiving terminal. The invention also provides a mobile communication system comprising the mobile terminal provided by any embodiment of the invention. The scheme of the invention is used for the unicast communication of the Internet of Vehicles, and the method effectively establishes the service connection between the sending end and the receiving end, and improves the signal transmission quality.

Description

technical field [0001] The present application relates to the field of mobile communication, and in particular to a V2X unicast communication method, terminal equipment and system. Background technique [0002] Among them, V2V (vehicle-to-vehicle communication) is the core of V2X communication technology. However, the D2D / V2X technology in the current 4G standard is a broadcast / multicast transmission mode, which does not implement the unicast D2D / V2X transmission mode, nor does it use MIMO, link adaptation, HARQ, etc., which are commonly used in unicast transmission. transmission technology. However, facing the development of mobile communication in the future 5G stage, broadcast mode D2D / V2X technology can no longer meet the needs. 5G V2V technology will expand from simple sensor sharing to one-to-one communication between vehicles, that is, unicast D2D / V2X technology. [0003] There are a series of new technical problems in the unicast D2D mode, especially in the design...
