Embodiment 1

[0081] A V2X communication method. The UE determines a resource pool available for V2X communication according to resource configuration parameters, including a sending resource pool and / or a receiving resource pool. The sending resource pool and the receiving resource pool are mutually orthogonal or overlap. And / or, the above resource configuration parameters further include sending resource pool period and / or receiving resource pool period, and / or, sending resource pool valid subframe and / or receiving resource pool valid subframe, and / or, sending resource pool subframe Range and / or receiving resource pool subframe range, and / or, sending resource block RB range and / or receiving resource pool resource block RB range, and / or, sending time window and / or receiving time window.

[0082] The method for determining a resource pool available for V2X communication at least includes: a method based on UE grouping, where UEs in different groups determine resource pools according to resou...

Embodiment 2

[0088] A V2X communication method, the method for a UE to select transmission resources includes: selecting transmission resources based on UE grouping, and selecting different transmission resources for different groups of UEs to transmit V2X communication signals.

[0089] The method for grouping UEs includes: grouping UEs based on geographic location and / or area range, UEs with different geographic locations or in different area ranges belong to different groups. For example, in V2P communication, according to whether the geographical location of the P-UE is in the lane group, the P-UE located in the lane and the P-UE outside the lane are in different UE groups, or the P-UEs in different lanes - UEs are respectively in different groups. Different groups of P-UEs select different resources to send P2V (Pedestrian to Vehicle, pedestrian users to vehicle users) signals, or base stations or roadside equipment schedule different resources for different groups of UEs, and differe...

Embodiment 3

[0093] A V2X communication method. The method for a terminal to send a V2X communication signal includes: if the terminal detects a V2X communication signal, sending the V2X communication signal at least once in the transmission resource pool cycle with the smallest delay after receiving the V2X communication signal; or, After receiving the V2X communication signal, send the V2X communication signal at least once within the time window W in the transmission resource pool period with the smallest delay, where the value of W is not greater than the transmission resource pool period, and can be configured by the network side or pre-configured as a fixed value. If the sending resource pool is determined based on groups, the UE selects the sending resource pool corresponding to the group to which it belongs to send the V2X communication signal. Wherein, the period of the sending resource pool with the smallest delay after receiving the V2X communication signal does not include the s...

Abstract

The invention provides a V2X communication method and apparatus in the Internet of Vehicles. The method comprises the following steps: determining a resource pool for V2X communication according to resource configuration parameters; selecting sending resources in the sending resources contained in the resource pool, and using the sending resources to send a first V2X communication signal; and / or, selecting receiving resources in the receiving resources contained in the resource pool, and using the receiving resources to receive a second V2X communication signal. By adoption of the V2X communication method and apparatus, the problems of low power consumption efficiency of end-to-end communication of the Internet of Vehicles, communication resource conflict and network congestion in the prior art are solved, and thus the effects of improving the power consumption efficiency of the end-to-end communication of the Internet of Vehicles, and relieving the communication resource conflict and the network congestion are realized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a V2X communication method and device in the Internet of Vehicles. Background technique [0002] The Internet of Vehicles refers to a large-scale system network for wireless communication and information exchange between vehicles and X (X: vehicles, roads, pedestrians, and the Internet, etc.) in accordance with agreed communication protocols and data interaction standards. Vehicle networking communication can enable vehicles to obtain driving safety, improve traffic efficiency, and obtain convenience or entertainment information. Classified from the objects of wireless communication, the Internet of Vehicles communication includes three different types: communication between vehicles (Vehicle to Vehicle, referred to as V2V), communication between vehicles and roadside equipment (Vehicle to Infrastructure, referred to as V2I) , and communication between vehicles and pedestrians...
