Abstract

The invention relates to a communication method and device which can be applied to the Internet of Vehicles, such as V2X, LTE-V and V2V. The method comprises the following steps: a first terminal device determines a first resource pool; the first terminal device detects control information of the second terminal device, the control information is used for indicating second service data of the second terminal device, and the control information comprises position information of the second terminal device, a first frequency domain resource and a period of the second service data; the first terminal device determines unavailable time-frequency resources in the first resource pool according to the position information of the first terminal device, the position information of the second terminal device, the first threshold, the first frequency domain resources and the period of the second service data; the first terminal device selects a first time-frequency resource from available time-frequency resources in the first resource pool to transmit first service data; and the first terminal device sends the first service data through the first time-frequency resource. Unavailable time-frequency resources are excluded according to the position of the terminal device, and resource collision is reduced.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] In the long term evolution (long term evolution, LTE) vehicle-to-everything (V2X), there are two transmission modes (mode), one is the base station allocation mode, which is defined as mode3 in the LTE standard, and the other is The second is user-selected mode, which is defined as mode 4 in the LTE standard. [0003] Among them, the user-selected mode is mainly applied to V2X communication without network coverage. Because there is no unified resource management of network devices, V2X terminal devices can only select resources in the resource pool to send data. In the user-selected mode, multiple V2X terminal devices may select resources in the same resource pool. In order to reduce the probability of resource collisions in V2X terminal devices, a method based on historical listening informati...
