Spectrum resource allocation method and device

Technical Field

Background

The Internet of Vehicles (IoV) is a huge interactive network formed by information such as vehicle position, speed and route, integrates some existing electronic information technologies such as sensing technology, network technology, computer technology and intelligent technology, and can complete collection of the environment and state information of the vehicle; by analyzing and processing the collected information, the optimal routes of different vehicles are calculated, the road conditions are reported in time, and effective guidance and supervision are carried out on the vehicles.

The Dedicated Short Range Communications (DSRC) technology can provide high-speed data transmission, ensure low delay of a communication link and reliability of a system, and is one of the most widely applied technologies in a vehicle networking system. Vehicle-to-road infrastructure communication, i.e., Vehicle-to-Vehicle (V2R) communication and inter-Vehicle communication, i.e., Vehicle-to-Vehicle (V2V) communication, can be achieved using DSRC technology.

In the current V2V communication or D2D communication, the allocation of the spectrum resource is that a device uses free spectrum resource particles in the whole spectrum resource for data transmission, as shown in fig. 1, the allocation of the spectrum resource is shown, in which the spectrum resource particles occupied by three devices for communication are shown. Specifically, there are two types of spectrum resource allocation scenarios: one is that the device (located on the vehicle) sends a spectrum resource request message to the base station, and the base station searches for idle spectrum resources from the spectrum resources and allocates the idle spectrum resources to the device after analyzing the spectrum resource request message, in this case, the base station controls the spectrum resource allocation of all the devices, which increases the network load of the base station; the other type is that when the device is to perform data transmission, the device monitors the spectrum resource occupation condition in all spectrum resources, and when the idle spectrum resource is monitored, the idle spectrum resource is utilized to perform data transmission.

Detailed Description

The technical solutions in the embodiments will be described clearly and completely with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the invention, the spectrum resource is a broad concept and consists of a plurality of spectrum resource particles, and all the spectrum resource particles form the whole spectrum resource; a part of the spectrum resource particles in the whole spectrum resource constitute a spectrum resource block.

In the specific implementation of the present invention, a process of clustering devices and dividing spectrum resources is first required.

The clustering process of the equipment specifically comprises the following steps: the base station determines at least one device in the coverage area as a cluster head device; and broadcasting the attribute information of each cluster head device in the coverage area so as to facilitate other devices to join the cluster.

When the base station designates the cluster head device, some devices can be randomly designated as the cluster head device from all the devices in the same driving direction in one or more areas with higher device density; the cluster head device can be a mobile device or a static device; the vehicle may be a device located on the vehicle, or a Road side device (RSU) or the like.

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

The principle of establishing the clusters can be preset, and the specific implementation process of establishing the clusters can refer to the prior art. For example: and other equipment selects the cluster head equipment which is closest to the equipment and has the same driving direction as target cluster head equipment according to the position, the driving direction and the like of the cluster head, and joins the cluster where the target cluster head equipment is located.

The process of dividing the frequency spectrum resources is specifically dividing the frequency spectrum resources into a first frequency spectrum resource pool and a second frequency spectrum resource pool; the first spectrum resource pool and the second spectrum resource pool both comprise at least one spectrum resource particle, wherein the first spectrum resource pool is used for providing spectrum resources for equipment with a cluster head; the second spectrum resource pool is used for providing spectrum resources for the device without the cluster head.

In a specific division, in an implementation manner of the present invention, the division may be performed according to the density of devices within the coverage area of the base station, for example: the density of the devices is large, for example, when the density of the devices is larger than a certain threshold, the devices are easy to form clusters, the number of the clusters is large, and therefore the proportion of the first spectrum resource pool is large; conversely, when the density of devices is small, e.g., less than a certain threshold, then the proportion of the second pool of spectrum resources is larger. The base station can periodically acquire the number of the devices in the current coverage range to acquire the density of the devices, and further adjust the number and the proportion of the 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 obtaining the density of the device, the utilization rates of the spectrum resources of the first spectrum resource pool and the second spectrum resource pool can be periodically counted, and when the utilization rate of the first spectrum resource pool is often high, the number of spectrum resource particles of the first spectrum resource pool can be appropriately increased; conversely, the number of spectral resource elements of the second pool of spectral resources is increased appropriately.

The embodiment of the invention can be applied to the application scene of V2V communication, and the equipment in the embodiment of the invention can be intelligent equipment positioned on a vehicle; the method and the Device can also be applied to an application scenario of Device-to-Device (D2D) communication, and the Device referred in the embodiment of the present invention may be a terminal Device such as a mobile phone.

On the basis of establishing the clusters and dividing the spectrum resources, the embodiments of the present invention provide different implementation processes of a spectrum resource allocation method.

Example 7:

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

The method is applied to a base station side, and comprises the following steps:

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

The cluster member information includes the number of cluster members, the traffic of the whole cluster, and the location information of each cluster member.

In the process of establishing the cluster, the cluster member equipment sends the attribute information of the running direction, the position, the speed and the like of the cluster head to the cluster head, and the cluster head collects, packs and reports the cluster member information to the base station.

1202: and allocating a spectrum resource block comprising at least one spectrum resource particle to each cluster head device from the first spectrum resource pool according to the cluster member information so that the cluster head device broadcasts the spectrum resource information of the spectrum resource block in a cluster.

After receiving the data packet sent by the cluster head device, the base station analyzes the data packet to obtain cluster member information, and allocates a spectrum resource block with a size corresponding to the cluster member information for the cluster head device from the first spectrum resource pool. For example: in the process of applying the invention to V2V communication, when the cluster members of a cluster are mainly concentrated on a road section, and there are more crossroads on the road section, the probability of vehicle collision is relatively high, so there are more vehicles in the cluster that send emergency signals, and the data packets for sending emergency signals are larger than the normal data packets, i.e. the traffic volume is large, so there are relatively more resources allocated to the cluster head of the cluster.

After receiving the spectrum resource blocks distributed by the base station, the cluster head device broadcasts the spectrum resource blocks to the cluster members in time, so that the cluster members only monitor the spectrum resource blocks corresponding to the cluster in which the cluster members are located, and data transmission is carried out by using the idle spectrum resource particles in the spectrum resource blocks.

According to the method for allocating the frequency spectrum resources, the frequency spectrum resources are divided into a first frequency spectrum resource pool and a second frequency spectrum resource pool, and equipment is divided into a plurality of clusters; on this basis, the base station can respectively allocate a spectrum resource block from the first spectrum resource pool to each cluster head device according to the cluster member information of each cluster, and broadcast the spectrum resource block to the cluster members through the cluster head devices, and the cluster member devices only monitor the spectrum resource block, so that the cluster member devices do not need to request the spectrum resource from the base station, the base station does not need to control the specific resource allocation condition of all the devices, the interaction times between the base station and the devices can be reduced, and the network load of the base station can be reduced. In summary, the method for allocating spectrum resources provided by the embodiments of the present invention can reduce the network load of the base station and reduce the power consumption of the device.

In the implementation process of the present invention, if there may be a case that some devices do not join a cluster, as a supplement to the above method, the base station further needs to broadcast spectrum resource information of the second spectrum resource pool within the coverage area, so that the devices that do not join the cluster monitor and use the idle spectrum resource particles in the second spectrum resource pool to perform data transmission. This procedure may be performed while the base station broadcasts the attribute information of the cluster head device.

Like the devices that join the cluster, the devices that do not join the cluster do not need to request the spectrum resource from the base station, do not need to monitor the whole spectrum resource, and only need to monitor the spectrum resource in the second spectrum resource pool, so the network load of the base station can be reduced and the power consumption of the devices can be reduced.

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

For understanding the present invention, an embodiment of the present invention further provides a schematic allocation diagram of spectrum resources obtained by the spectrum resource allocation method provided in the embodiment of the present invention, as shown in fig. 14. Wherein, in the first spectrum resource pool, spectrum resource blocks allocated by four cluster heads of CH1, CH2, CH3 and CH4 are respectively shown; in the second spectrum resource pool, spectrum resources occupied by the two devices are respectively shown.

Fig. 15 is a flowchart illustrating a second method for allocating spectrum resources according to an embodiment of the present invention.

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

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

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

1302: and when the spectrum resource utilization rate is lower than a first threshold value, releasing a first number of spectrum resource particles from the resource blocks allocated to the cluster head device.

The first threshold may be a fixed value, for example: values between 10% and 20%, values that can also be dynamically varied, for example: and adjusting by continuously counting the resource utilization rate.

The first number and the second number referred to in the present embodiment are for convenience of description, and do not refer to specific numbers.

When the spectrum resource utilization rate of a certain cluster is low, a part of spectrum resource particles need to be released in time, for example: and obtaining and releasing the spectrum resource particles with lower utilization rate by counting the existing spectrum resource particles.

1303: and when the spectrum resource utilization rate is higher than a second threshold value, adding a second number of spectrum resource particles to the cluster head equipment.

The second threshold may be a fixed value, for example: values between 80% and 90%, and also dynamically varying values, such as: the resource utilization rate is continuously counted and adjusted.

When the utilization rate of the spectrum resource of a certain cluster is high, in order to ensure that the spectrum resource provided for the cluster is sufficient to provide reliable communication between devices, the spectrum resource allocated for the cluster needs to be increased appropriately.

In addition, as a substitute for the

above steps

1301 and 1303, in another implementation manner of the present invention, the cluster head device may periodically count the size of the spectrum resource utilization rate of the cluster and then determine the spectrum resource utilization rate, and when the spectrum resource utilization rate is lower than a certain threshold, the cluster head device reports to the base station so that the base station releases the unused spectrum resource in time; when the spectrum resource utilization rate is higher than a certain threshold value, the cluster head device also reports to the base station so that the base station can 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 needs to broadcast the updated spectrum resource information of the spectrum resource block in the cluster in time.

In addition, when the cluster head leaves the coverage area of the base station, the base station needs to delete the original cluster head information or add a new cluster head device and broadcast periodically. For example: and the base station periodically monitors whether each appointed cluster head device is in the coverage area. And if the cluster head equipment which is not in the coverage area exists, deleting the attribute information of the cluster head equipment which is not in the coverage area, appointing new cluster head equipment and broadcasting the attribute information of the new cluster head equipment.

1401: and the cluster head equipment acquires the cluster member information and reports the cluster member information to the base station.

1402: and receiving the frequency spectrum resource information of the frequency spectrum resource block distributed by the base station according to the cluster member information, wherein the frequency spectrum resource block comprises at least one frequency spectrum resource particle.

1403: and the cluster head equipment broadcasts the spectrum resource information of the spectrum resource block in the cluster so as to facilitate the cluster members to monitor the spectrum resource block and utilize the idle spectrum resource particles therein for data transmission.

Corresponding to the allocation method of the spectrum resources applied to the base station side and the cluster head device side, an embodiment of the present invention further provides an allocation method of the spectrum resources, which is applied to the non-cluster head device side, as shown in fig. 17, the method includes:

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

When the non-cluster-head device selects the cluster-head device, the cluster-head device which is closest to the non-cluster-head device and has the same driving direction as the non-cluster-head device can be used as the target cluster-head device.

1502: and when data transmission is needed, monitoring a spectrum resource block broadcasted by the target cluster head device, wherein the spectrum resource block is located in the first spectrum resource pool.

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

1503: and carrying out data transmission by using the idle spectrum resource particles in the spectrum resource block.

According to the method for allocating the spectrum resources, the spectrum resources are divided into the first spectrum resource pool and the second spectrum resource pool, the equipment is divided into the plurality of clusters, cluster members do not need to request the spectrum resources from the base station, the whole spectrum resources do not need to be monitored, and only the spectrum resources allocated by the cluster head equipment of the cluster where the cluster members are located need to be monitored, so that the network load of the base station can be reduced, and meanwhile, the power consumption of the equipment is reduced.

In the implementation of the present invention, there may be some cases where the device does not join the cluster, and as a supplement to the above method, the method further comprises:

Similar to the devices that join the cluster, the devices that do not join the cluster do not need to request the spectrum resource from the base station, do not need to monitor the whole spectrum resource, and only need to monitor the spectrum resource in the second spectrum resource pool, so the network load of the base station can be reduced and the power consumption of the devices can be reduced.
