Resource scheduling method and resource scheduling device for vehicle communication

Abstract

The present invention provides a resource scheduling method and a resource scheduling device for vehicle communication, wherein the resource scheduling method includes: during the process of transmitting vehicle communication messages based on configuration parameters for semi-static scheduling allocated by the base station, detecting vehicle communication services Whether the message characteristics of the vehicle communication service have changed; if it is detected that the message characteristics of the vehicle communication service have changed, the message characteristics of the vehicle communication service after the change will be sent to the base station through the instruction signaling; the receiving base station will redistribute the half Configuration parameters for static scheduling; configuration parameters for semi-static scheduling based on reallocation continue to transmit vehicle communication messages. The invention enables the base station to sense the change in time when the message characteristics of the vehicle communication service carried out by the vehicle communication terminal change, and then redistribute the configuration parameters of the SPS to the vehicle communication terminal, ensuring that the configuration parameters of the SPS can be adapted in time Dynamic changes in vehicle communication messages.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a resource scheduling method for vehicle communication and a resource scheduling device for vehicle communication. Background technique [0002] V2X (Vehicle to X, vehicle-to-target communication) is a project approved by 3GPP RAN#68, which mainly studies the vehicle data transmission scheme based on the 3GPP communication protocol. V2X includes V2V (Vehicle to Vehicle, vehicle-to-vehicle communication), V2P (Vehicle to Pedestrian, vehicle-to-person communication), V2I (Vehicle to Infrastructure, vehicle-to-road communication), etc. In principle, V2V communication can realize the transmission of V2V messages through the Uu interface (the interface between the user equipment and the base station), the PC5 interface (the interface between the user equipment and the user equipment), or the combination of the Uu interface and the PC5 interface. Among them, the scheme ...

Problems solved by technology

[0005] However, for vehicle communication messages, the size and / or period of the V-UE message may change at any time with changes in external conditions (such as speed, location, etc.), and only rely on eNB's pre-estimation for SPS configuration / Reconfiguration, it may take a certain delay to observe this change, which may have a greater impact on some delay-sensitive emergency services (such as V2V messages such as failure / out of control)

In short, if the transmission of V2V messages reuses the existing SPS mechanism, only DENM and BSM types can be supported, and CAM type V2V messages cannot be well supported.
