Embodiment Construction

[0075] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0076] In the related art, for the vehicle-mounted terminals in the Internet of Vehicles, the moving speed may be relatively fast, resulting in low communication quality. After the reference signal is sent, the opposite vehicle terminal may fail to receive it. Not conducive to communication transmission.

[0077] In order to solve the above problems, in this embodiment, the reference signal tr...

Abstract

The present invention relates to a method and apparatus for transmitting a reference signal. The method includes the steps: obtaining a current traveling speed; determining a corresponding reference signal transmission density according to the speed level to which the current traveling speed belongs; and transmitting a reference signal to a connected opposite vehicle-mounted terminal according tothe reference signal transmission density.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for transmitting a reference signal. Background technique [0002] Among related technologies, with the development of Internet technology, Internet of Vehicles has become a hot research topic. How to communicate reliably between vehicles in the Internet of Vehicles has been the focus of long-term research. The communication technology of the Internet of Vehicles can learn from the communication technology of the mobile communication system. In a mobile communication system, a user equipment sends a reference signal to a base station for channel estimation and the like. However, for the Internet of Vehicles, the reference signal transmission method in the mobile communication system may not meet the demand due to the fast moving speed of the vehicle. Contents of the invention [0003] Embodiments of the present invention provide a method an...
