Problems solved by technology

Since the resource allocation, scheduling and coordination entities within the cellular network coverage and outside the cellular network coverage are different, during the movement of the vehicle, if the vehicle moves from within the network coverage to outside the network coverage, or from outside the network coverage to within the network coverage, resource collisions will occur. Issues that generate road safety app outages

Embodiment 1

[0169] Embodiment 1: Resource coordination without resource collision

[0170] image 3 It is a schematic diagram of nodes in and out of coverage without resource collision. As shown in the figure, car A is in the edge area within the coverage of the base station, and car B is outside the coverage of the base station.

[0171] There are 2 possible situations for the car:

[0172] Case 1. Car A continuously sends D2D SS, and does not receive synchronization signals from nodes outside the coverage, and does not need to send resource coordination messages;

[0173] Case 2. Car A can receive the D2D SS sent by car B outside the coverage and needs to send a resource coordination message;

[0174] For case 2 where resource coordination is required, the implementation is as follows:

[0175] step one:

[0176] Car A can receive the D2D SS sent by car B outside the coverage. Since the D2D SS sequence in the eNB coverage is different from that outside the coverage, the car A confirms that the car ...

Embodiment 2

[0190] Embodiment 2: strong interference information requires resource coordination

[0191] Figure 4 A schematic diagram of nodes in and out of coverage reported for strong interference. As shown in the figure, cars A and D are in the edge area of ​​the base station coverage, car C is in the base station coverage, and car B is out of coverage. Among them, car B and car C occupy the same time-frequency resources for transmission, and car D detects that the transmission resources of car B and car C collide. It can be implemented as follows:

[0192] step one:

[0193] Since car A is in the edge area covered by the base station, it needs to continuously send D2D SS. When car A receives the D2D SS sent by car B outside the coverage, because the D2D SS sequence in the eNB coverage is different from that outside the coverage, the car A confirms that the car A is at the edge of the base station coverage and there is the car B outside the coverage node around.

[0194] Specifically, when ...

Embodiment 3

[0216] Embodiment 3: There is strong interference and strong interference information requires resource coordination

[0217] Figure 5 It is a schematic diagram of nodes in and out of coverage without resource collision. As shown in the figure, car A, car D, and car C are in the edge area of ​​the base station coverage, car E is in the base station coverage, and car B and car F are out of coverage. Among them, car B and car C occupy the same time-frequency resources for transmission, and car D detects that the transmission resources of car B and car C collide. Among them, car B and car C occupy the same time-frequency resources for transmission, and car D detects that the transmission resources of car B and car C collide. It can be implemented as follows:

[0218] step one:

[0219] Car A is in the coverage of the base station and continuously sends D2D SS. When car A receives the D2D SS from car B outside the coverage, because the D2D SS sequence in and out of eNB coverage is dif...

Abstract

The present invention discloses a resource information sending and broadcasting method and device. The resource information sending method comprises the steps of determining the resources used by the second kind of nodes and the resources used by the first kind of nodes, and determining the first kind of nodes of receiving the resource coordination messages, wherein the first kind of nodes are located within a base station signal coverage range, and the second kind of nodes are located beyond the base station signal coverage range; sending the resource coordination messages to the determined first kind of nodes, and indicating the first kind of nodes to broadcast the content of the resource coordination messages, wherein the resource coordination messages carry the resource information of the first kind of nodes and the second kind of nodes. According to the present invention, the resource continuity during the process that the nodes move at the network coverage edges, is guaranteed, the resource collision is reduced, and the utilization rate of the system resources is improved.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a method and device for sending and broadcasting resource information. Background technique [0002] The vehicle’s active and safe Internet of Vehicles communication system is based on wireless communication technology to obtain vehicle and road information. Through information interaction and sharing between vehicles and roads, intelligent collaboration and cooperation between vehicles and infrastructure are realized to achieve optimal utilization of the system Resources, improve road traffic safety, improve the driver’s experience, and alleviate traffic congestion. [0003] The vehicle-road cooperative communication system needs to ensure the low-latency and high-reliability characteristics of road safety applications. The cellular network allocates and coordinates resources within the network coverage, while the vehicle-road cooperative communication syste...
