Problems solved by technology

[0007] In V2X technology, vehicle UEs (first users) can use sensing-based transmission resource selection to avoid resources already occupied by other UEs to avoid transmission collisions, but there is a class of pedestrian UEs (second users) that can randomly select transmission resources resources, cannot avoid sending collisions with other UEs
When the first user and the second user coexist, the existing transmission resource pool division method of RAN2 has the problem of low resource utilization or unavoidable transmission collision

Embodiment 1

[0081] see image 3 , the figure shows a resource pool configuration method, the specific steps are as follows:

[0082] Step 301, the first user obtains the first resource pool configuration signaling, and the first resource pool configuration signaling includes: the configuration signaling of the resource pool sent by the first user and the configuration signaling of the resource pool sent by the second user;

[0083] It should be noted that the above-mentioned first user may be a V-UE in the V2X system, and the above-mentioned second user may be a P-UE in the V2X system, and the P-UE may be a random P-UE, wherein the random P-UE Refers to: a P-UE that uses a random resource selection method to select transmission resources.

[0084] combine Figure 5 , the first resource pool configuration signaling acquired in step 301 includes: configuration signaling of overlapping resource pools, non-overlapping resource pools, and randomly selected resource pools of the V-UE.

Embodiment 2

[0094] see Figure 4 , the figure shows a resource pool configuration method, the specific steps are as follows:

[0095] Step 401, the third user obtains the second resource pool configuration signaling;

[0096] Step 402, the third user configures the third user transmission resource pool according to the configuration signaling of the third user transmission resource pool;

[0097] If the third user is a pedestrian-like user who uses a random resource selection method to select transmission resources, the second resource pool configuration signaling includes: a configuration signaling for randomly selecting a resource pool;

[0098] If the third user is a pedestrian-like user who selects transmission resources using a partial sensing resource selection method, the second resource pool configuration signaling includes: a configuration signaling for randomly selecting a resource pool and a configuration signaling for partially sensing a transmission resource pool make.

Embodiment 3

[0118] In this embodiment, a resource pool division model is given for V-UEs in the V2X system, P-UEs that randomly select transmission resources, and P-UEs that select transmission resources based on partial sensing.

[0119] For the convenience of description in the following:

[0120] random P-UE: a P-UE that uses random resource selection to select transmission resources;

[0121] partial sensing P-UE: P-UE for resource selection based on partial sensing;

[0122] Random selection resource pool: a transmission resource pool in which the P-UE can select transmission resources using a random resource selection manner.

[0123] see Figure 5 , the figure shows a resource pool division model, and the V-UE transmission resource pool includes: transmission resource pools of overlapping parts and transmission resource pools of non-overlapping parts.

[0124] It should be noted that if the V-UE only uses the non-overlapping part of the transmission resource pool, the transmissi...

Abstract

The invention provides a resource pool allocation method and device, which can improve the resource utilization rate of the system while avoiding unnecessary collisions. The resource pool allocation method comprises the following steps: a first user obtains a first resource pool configuration signaling, wherein the first resource pool configuration signaling comprises a configuration signaling ofa first user sending resource pool and a configuration signaling of a second user sending resource pool; and the first user configures the first user sending resource pool according to the configuration signaling of the first user sending resource pool, wherein the first user sending resource pool comprises a first user overlapping part resource pool and a first user non-overlapping part resourcepool; and the first user overlapping part resource pool is the overlapping part of the first user sending resource pool and the second user sending resource pool configured by the configuration signaling of the second user sending resource pool.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource pool allocation method and device for vehicle users and pedestrian-like users in V2X. Background technique [0002] V2X (Vehicle-to-Everything) technology: V2X, or vehicle network technology, establishes a new automotive technology and the development direction of future intelligent transportation by integrating GPS navigation technology, vehicle-to-external information exchange technology and wireless communication technology. V2X technology currently includes two main business models, V2V (Vehicle-to-Vehicle), which is communication between vehicles, and V2P (Vehicle-to-pedestrian), which is communication between vehicles and pedestrians. [0003] V2V (Vehicle-to-Vehicle) technology: In inter-vehicle communication technology, vehicles can exchange V2V services such as location, vehicle speed and form direction through base station forwarding or D2D (De...
