Embodiment 1

[0133] This embodiment is aimed at the scenario where the OBU in the coverage of the base station autonomously selects resources to send V2X services; Figure 9 is a flowchart of a method according to an optional embodiment of the present invention, such as Figure 9 As shown, the steps of this embodiment include:

[0134] Step S901, the base station allocates a resource pool;

[0135] Wherein, the base station notifies the allocated resource pool through a system broadcast message or a dedicated RRC message, and the resource pool includes at least one of the following resources: scheduling information time-frequency resources, service data time-frequency resources, V2X scheduling information and / or service retransmission times, sending Probability, scheduling information MCS, business MCS, SPS scheduling cycle.

[0136] Considering that the scheduling information is generally sent at a fixed frequency domain position in the subframe, the time domain position of the scheduli...

Embodiment 2

[0150] This embodiment is for the scenario where the OBU outside the coverage of the RSU sends the V2X service; Figure 10 It is a flow chart of the method according to the second optional embodiment of the present invention, such as Figure 10 Shown, the step of this embodiment method comprises:

[0151] Step S1001, pre-allocate a V2X resource pool.

[0152] Wherein, the pre-allocation is stored locally in the OBU when the OBU is within the coverage of the base station or when the OBU leaves the factory, such as in an OBU memory card; the pre-allocation is generally completed by the base station or network management. The resource pool includes: a sending resource pool and a receiving resource pool. The sending resource pool is used to send V2X services outside the coverage of the base station, and the receiving resource pool is used for the OBU to monitor V2X services outside the coverage of the base station.

[0153] The specific content of the resource pool is similar t...

Embodiment 3

[0160] This embodiment is aimed at the scenario where the OBU within the RSU coverage uses dynamic scheduling to send V2X services; Figure 11 It is a flowchart of the third method according to the optional embodiment of the present invention, such as Figure 11 As shown, the steps of the method of this embodiment include:

[0161] In step S1101, the OBU requests the base station to allocate V2X resources.

[0162] Wherein, the OBU has V2X information to be sent, and the OBU sends indication information to the base station through RRC signaling, and the indication information is used to request the base station to allocate resources.

[0163] Step S1102, the base station allocates V2X communication resources.

[0164] Wherein, the base station allocates V2X scheduling information resources and V2X service resources.

[0165] Step S1103, the base station sends scheduling information.

[0166] Wherein, the base station sends the scheduling information through the DCI format5...

Abstract

The invention provides a vehicle to everything (V2X) business transmission method and device, and a resource allocation method and device. The V2X business transmission method includes that a first onboard unit OBU acquires the transmission resources for transmitting the V2X business, the transmission resources include the resources required to send the V2X business data and scheduling information in the V2X business, the scheduling information refers to the information indicating the resource scheduling of the V2X business data, the first OBU transmits the scheduling information and the V2X service data to the second OBU on the transmission resources, the scheduling information and the V2X business data are subjected to frequency domain multiplexing in the same subframe in the transmission resources and the scheduling information indicates that the V2X business data is subjected to resource allocation in the same and / or different subframes. According to the invention, the problem that the D2D technology in the prior art can only send the resource scheduling information and V2X business data separately is solved, and the gaps in the relevant technology are filled.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for sending an Internet of Vehicles service, and a method and device for configuring resources. Background technique [0002] With the rapid economic and social development, China's car ownership has grown rapidly, and road traffic accidents have occurred frequently, which has become one of the important factors affecting the public's sense of security in recent years. Road traffic safety has become a basic issue affecting social harmony and improving people's livelihood one. China urgently needs to improve traffic safety in terms of technology, policy, education and other aspects, and improving vehicle safety design is an important part of it. [0003] Technologies to improve vehicle safety are mainly divided into passive safety technologies and active safety technologies. Passive safety technology is used to protect people and objects inside and ...
