Resource scheduling method and resource scheduling device for vehicle communication

Abstract

The invention provides a resource scheduling method and a resource scheduling device for vehicle communication, wherein the resource scheduling method comprises the following steps of: detecting whether message characteristics of a vehicle communication service are changed or not in a process of transmitting a vehicle communication message based on a configuration parameter for performing semi-static scheduling distributed by a base station; if detecting that the message characteristics of the vehicle communication service are changed, sending the changed message characteristics of the vehicle communication service to the base station through indication signalling; receiving a configuration parameter for performing semi-static scheduling redistributed by the base station according to the changed message characteristics; and continuously transmitting the vehicle communication message based on the re-distributed configuration parameter for performing semi-static scheduling. According to the resource scheduling method and the resource scheduling device for vehicle communication provided by the invention, when the message characteristics of the vehicle communication service carried by a vehicle communication terminal are changed, the base station can know the change in time; therefore, the base station can redistribute a configuration parameter of a SPS to the vehicle communication terminal; and thus, the configuration parameter of the SPS can be suitable for dynamic change of the vehicle communication message in time.

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.
