The use of DSRC technology can realize the communication between vehicles and road infrastructure, that is, vehicle-to-road (Vehicle to Road, V2R) communication and inter-vehicle communication, that is, vehicle-to-vehicle (Vehicle to Vehicle, V2V) communication.

In the current V2V communication or D2D communication, the allocation of spectrum resources is that the device uses the idle spectrum resource particles in the entire spectrum resource for data transmission. Figure 1 shows the allocation of spectrum resources, which shows three devices. Spectrum resource particles occupied for communication. Specifically, there are two types of spectrum resource allocation: one is that the device (located on the vehicle) sends a spectrum resource request message to the base station, and the base station parses the spectrum resource request message and finds idle spectrum resources from the spectrum resources and allocates them to the device. , in this case, the base station controls the spectrum resource allocation of all devices, which increases the network load of the base station; another type is that when the device wants to transmit data, the device monitors the spectrum resource occupancy in all spectrum resources.

Detailed ways

The technical solutions in this embodiment will be clearly and completely described below with reference to the drawings in this embodiment. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In the present invention, spectrum resource is a concept in a broad sense, which is composed of multiple spectrum resource particles, all spectrum resource particles constitute the entire spectrum resource, and some spectrum resource particles in the entire spectrum resource constitute a spectrum resource block.

In the specific implementation of the present invention, the process of clustering equipment and dividing spectrum resources needs to be performed first.

The clustering process of the referred device is specifically as follows: the base station determines at least one device within the coverage area as the cluster head device; and broadcasts the attribute information of each cluster head device within the coverage area so that other devices can join the cluster.

Among them, when the base station designates the cluster head device, it can randomly designate some devices as the cluster head device from all the devices in the same driving direction in one or more areas with relatively large device density; the cluster head device can be A moving device may also be a stationary device; it may be a device located on a vehicle, or a roadside device (Road sideUint, RSU), or the like.

The attribute information of the cluster head device includes the position of the cluster head, the driving direction, and the like.

The principle of establishing a cluster may be preset, and the specific implementation process of establishing a cluster may refer to the prior art. For example, according to the position and driving direction of the cluster head, other devices select the cluster head device closest to itself and in the same driving direction as the target cluster head device, and join the cluster where the target cluster head device is located.

The process of dividing the spectrum resources is specifically as follows: dividing the spectrum resources into a first spectrum resource pool and a second spectrum resource pool; both the first spectrum resource pool and the second spectrum resource pool include at least one spectrum resource particle, The first spectrum resource pool is used to provide spectrum resources for devices with cluster heads; the second spectrum resource pool is used to provide spectrum resources for devices without cluster heads.

When the specific division is carried out, in an implementation manner of the present invention, the division can be made according to the density of the devices within the coverage of the base station. For example, when the density of the devices is relatively large, for example, when the density is greater than a certain threshold, it means that the devices are easy to form clusters, and the clusters are easy to form. The number of devices will be larger, so the proportion of the first spectrum resource pool is larger; on the contrary, when the density of devices is small, for example, less than a certain threshold, the proportion of the second spectrum resource pool is larger. The base station may periodically acquire the number of devices within the current coverage area to acquire the density of the devices, and then adjust the number and proportion of spectrum resource particles in the first spectrum resource pool and the second spectrum resource pool.

In another implementation manner of the present invention, in addition to periodically acquiring the density of devices, the utilization rate of spectrum resources in the first spectrum resource pool and the second spectrum resource pool may also be periodically counted. When the utilization rate of the spectrum resource is often high, the number of spectrum resource particles in the first spectrum resource pool may be appropriately increased; on the contrary, the number of spectrum resource particles in the second spectrum resource pool may be appropriately increased.

The embodiments of the present invention can be applied to an application scenario of V2V communication, and the devices referred to in the embodiments of the present invention can be smart devices located on vehicles; and can also be applied to device-to-device (Device-to-Device, D2D) communication In the application scenario of the present invention, the device referred to in the embodiment of the present invention may be a terminal device such as a mobile phone.

Based on the above-described cluster establishment and spectrum resource division, embodiments of the present invention provide different implementation processes of a spectrum resource allocation method.

Example 7:

FIG. 13 is a schematic flowchart of a first method for allocating spectrum resources according to an embodiment of the present invention.

Wherein, the method is applied to the base station side, and the method includes:

1201: The base station receives the cluster member information sent by each cluster head device.

The cluster member information referred to includes the number of cluster members, the business volume of the entire cluster, the location information of each cluster member, and the like.

In the process of establishing a cluster, the cluster member device will send its own attribute information such as driving direction, position and speed to the cluster head, and the cluster head will collect the cluster member information, package it and report it to the base station.

1202: Allocate a spectrum resource block including at least one spectrum resource element to each of the cluster head devices from the first spectrum resource pool according to the cluster member information, so that the cluster head device can broadcast the spectrum resource block within the cluster spectrum resource information.

After receiving the data packet sent by the cluster head device, the base station parses the data packet to obtain cluster member information, and allocates the cluster head device from the first spectrum resource pool with a spectrum resource block of a size corresponding to its cluster member information. For example: in the process of applying the present invention to V2V communication, when the cluster members of a certain cluster are mainly concentrated in a certain road section, and there are many intersections in this road section, the probability of vehicle collision will be relatively large, so in the There may be more vehicles sending emergency signals in this cluster, and the data packets used to send emergency signals are larger than ordinary data packets, that is, the traffic volume is larger, so the resources allocated to the cluster head of the cluster are relatively large. more.

After receiving the spectrum resource block allocated by the base station, the cluster head device broadcasts it to the cluster members in time, so that the cluster members can only monitor the spectrum resource block corresponding to the cluster where they belong, and use the free spectrum resource particles in it for data transmission.

The spectrum resource allocation method provided by the present invention divides the spectrum resources into two parts: the first spectrum resource pool and the second spectrum resource pool, and divides the equipment into multiple clusters; on this basis, the base station can The information allocates spectrum resource blocks from the first spectrum resource pool for each cluster head device, and broadcasts it to the cluster members through the cluster head device. The cluster member devices only need to monitor the spectrum resource block, so the cluster member devices do not need to request the base station. Spectrum resources, the base station does not need to control the specific resource allocation of all devices, which can reduce the number of interactions between the base station and the device, thus reducing the network load of the base station. In addition, cluster member devices do not need to monitor the entire spectrum resources, only need to monitor the cluster where they are located. Only the spectrum resources allocated by the cluster head device can be used, so the power consumption of the device can be reduced. To sum up, the above-mentioned spectrum resource allocation method provided by the embodiment of the present invention can reduce the network load of the base station and reduce the power consumption of the device.

During the implementation of the present invention, some devices may not be added to the cluster. As a supplement to the above method, the base station also needs to broadcast the spectrum resource information of the second spectrum resource pool within the coverage area, so as to facilitate the devices that are not added to the cluster. Monitoring and utilizing idle spectrum resource particles in the second spectrum resource pool for data transmission. This process may be performed while the base station broadcasts the attribute information of the cluster head device.

In this way, similar to the devices that have joined the cluster, the devices that have not joined the cluster do not need to request spectrum resources from the base station, nor do they need to monitor the entire spectrum resources, but only need to monitor the spectrum resources in the second spectrum resource pool, which can also reduce the network load of the base station. while reducing the power consumption of the device.

FIG. 14 is a schematic diagram of allocation of spectrum resources according to an embodiment of the present invention.

In order to understand the present invention, an embodiment of the present invention further provides a schematic diagram of spectrum resource allocation obtained according to the above-mentioned spectrum resource allocation method provided by an embodiment of the present invention, as shown in FIG. 14 . Among them, in the first spectrum resource pool, the spectrum resource blocks allocated by the four cluster heads CH1, CH2, CH3 and CH4 are respectively shown; in the second spectrum resource pool, the spectrum resource blocks occupied by the two devices are respectively shown spectrum resources.

FIG. 15 is a schematic flowchart of a second spectrum resource allocation method according to an embodiment of the present invention.

In addition, in order to improve the utilization rate of spectrum resources, the base station can adjust the size of the spectrum resource block allocated to the cluster in time according to the size of the cluster traffic. When the traffic volume in the cluster is relatively small, the base station should release the unused spectrum resources in time; When the traffic volume is relatively large, the base station should add new spectrum resources to the cluster in time. Therefore, the method, as shown in Figure 15, further includes:

1301: The base station acquires the spectrum resource utilization rate reported by each cluster head device.

The cluster head device can periodically count the utilization of the spectrum resource blocks corresponding to the cluster and report it to the base station.

1302: When the spectrum resource utilization rate is lower than a first threshold, release a first number of spectrum resource particles from the resource block allocated for the cluster head device.

The first threshold may be a fixed value, such as a value between 10% and 20%, or a value that changes dynamically, such as adjusting by continuously counting resource utilization.

The first quantity and the second quantity referred to in this embodiment are for convenience of description and do not refer to specific quantities.

When the spectrum resource utilization rate of a cluster is low, it is necessary to release a part of spectrum resource particles in time. For example, by counting the existing spectrum resource particles, acquire and release spectrum resource particles with low utilization rate.

1303: When the spectrum resource utilization rate is higher than a second threshold, add a second number of spectrum resource particles to the cluster head device.

The second threshold may be a fixed value, such as a value between 80% and 90%, or a dynamically changing value, such as adjusting by continuously counting resource utilization.

When the spectrum resource utilization rate of a certain cluster is relatively high, in order to ensure that the spectrum resources provided for the cluster are sufficient to provide reliable communication between devices, it is necessary to appropriately increase the spectrum resources allocated to the cluster.

In addition, as an alternative to the above steps 1301 and 1303, in another implementation manner of the present invention, the cluster head device can periodically count the size of the spectrum resource utilization rate of the cluster to determine the spectrum resource utilization rate. When the resource utilization rate is lower than a certain threshold, the cluster head device reports to the base station so that the base station can release the unused spectrum resources in time; when the spectrum resource utilization rate is higher than a certain threshold, the cluster head device also reports to the base station to facilitate the base station Add new spectrum resources to the cluster in time. The base station needs to notify the cluster head device of the updated spectrum resource information of the spectrum resource block, and the cluster head device should broadcast the updated spectrum resource information of the spectrum resource block in the current cluster in time.

In addition, when the cluster head leaves the coverage area of the base station, the base station should delete the original cluster head information in time or add a new cluster head device and broadcast it periodically. For example, the base station periodically monitors whether each designated cluster head device is within the coverage area. If there is a cluster head device that is not within the coverage range, delete the attribute information of the cluster head device that is not within the coverage range, specify a new cluster head device, and broadcast the attribute information of the new cluster head device.

As shown in FIG. 17 , this method include:

1501: The non-cluster head device selects a target cluster head device to join the cluster according to the attribute information of the cluster head device broadcast by the base station.

Among them, when the non-cluster head device selects the cluster head device, the cluster head device with the closest distance to itself and the same driving direction may be used as the target cluster head device.

1502: When data transmission is required, monitor a spectrum resource block broadcast by the target cluster head device, where the spectrum resource block is located in the first spectrum resource pool.

During the execution of this step, the device only needs to monitor the spectrum resource block allocated by the cluster head device of the cluster where it is located, and does not need to monitor the entire spectrum resource block.

1503: Use the idle spectrum resource elements in the spectrum resource block to perform data transmission.

In the spectrum resource allocation method provided by the embodiment of the present invention, the spectrum resources are divided into two parts, the first spectrum resource pool and the second spectrum resource pool, and the devices are divided into multiple clusters. Cluster members do not need to request spectrum resources from the base station, nor do they need to monitor The entire spectrum resource only needs to monitor the spectrum resource allocated by the cluster head device of the cluster where it is located, thus reducing the network load of the base station and reducing the power consumption of the device.

Reduce device power consumption.
