Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a vehicle-to-vehicle system communication resource allocation, selection method, base station and terminal, in order to solve the problem that each existing zone with the same number allocates the same communication resources, which cannot be guaranteed when needed The zone at the communication intersection with more communication resources has enough available communication resources, so that the V2X message of the vehicle at the traffic intersection cannot have communication resources to send, which is likely to cause traffic accidents

Embodiment 1

[0047] Such as figure 2 As shown, the embodiment of the present invention provides a communication resource allocation method for a vehicle-to-vehicle system, which is applied to the base station side, including:

[0048] Step 21, obtaining area information of preset hotspot areas that need to be additionally configured with resource pools;

[0049] It should be noted that the preset hotspot area is an area with a large number of vehicles, such as an intersection, a parking lot, etc., and the area information includes: the latitude and longitude coordinates of the preset hotspot area or the system-divided area covering the preset hotspot area Identification; wherein, the latitude and longitude coordinates of the preset hotspot area include: the latitude and longitude coordinates of the center of the preset hotspot area or the latitude and longitude coordinates of multiple points locating the preset hotspot area.

[0050] It should also be noted that the latitude and longitud...

Embodiment 2

[0077] Such as image 3 As shown, the embodiment of the present invention provides a base station 30, including:

[0078] The first acquiring module 31 is configured to acquire area information of a preset hotspot area that requires an additional resource pool configuration;

[0079] The sending module 32 is configured to send the area information and additionally allocated communication resource information for the preset hotspot area to the terminal.

[0080] Specifically, the area information includes: the latitude and longitude coordinates of the preset hotspot area or the area identification of the system-divided area covering the preset hotspot area; wherein, the latitude and longitude coordinates of the preset hotspot area include: the central latitude and longitude of the preset hotspot area Coordinates or latitude and longitude coordinates of multiple points for locating preset hotspot areas.

[0081] Optionally, when the area information is the latitude and longitu...

Abstract

The invention provides a communication resource allocation method and communication resource selection method of a vehicle-to-vehicle system, a base station and a terminal, and relates to the technical field of communication. The communication resource allocation method comprises the steps of: obtaining zone information of a pre-set hotspot zone configured by a resource pool, which needs to be extra increased; and sending the zone information and communication resource information extra allocated to the pre-set hotspot zone to the terminal. By means of the scheme, some communication resourcesare excessively allocated to a hotspot zone, where vehicles are relatively centralized; the problem that communication resources in the hotspot zone, where the vehicles are relatively centralized, arenot enough can be relieved; in this way, normal communication of the vehicles is ensured; and the running security of the vehicles is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication resource allocation and selection method, a base station and a terminal for a vehicle-to-vehicle system. Background technique [0002] In the existing long-term evolution vehicle-to-vehicle (LTE V2V) system, the concept of zone (zone) is proposed, that is, the area covered by the base station is divided into N areas, and each area with the same number uses the same resource pool. At the same time, ensure that the areas with the same number are separated in space to ensure the minimum interference, such as figure 1 As shown, it is a division method of zone. The base station (eNB) configures the resource pool of each zone to the terminal (UE) through a system resource block (SIB) message. [0003] The problem with existing technical solutions is that the number of vehicles at traffic intersections will be greater than the number of vehicles in other areas, ...
