detailed description

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

In the specific implementation of the present invention, it is first necessary to carry out the processes of clustering devices and dividing spectrum resources.

Wherein, the clustering process of the devices referred to specifically includes: the base station determines at least one device within the coverage area as a cluster head device; 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 specifies 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 where the device density is relatively high; the cluster head device can be Mobile equipment can also be stationary equipment; it can be equipment located on the vehicle or roadside equipment (Road side Uint, RSU), etc.

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

The principle of establishing a cluster can be preset, and the specific implementation process of establishing a cluster can 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.

Wherein, the process of dividing the spectrum resources is specifically, dividing the spectrum resources into first frequency A spectrum resource pool and a second spectrum resource pool; the first spectrum resource pool and the second spectrum resource pool each include at least one spectrum resource element, wherein 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.

For specific division, in an implementation of the present invention, it can be divided according to the density of the equipment within the coverage of the base station. For example, if the density of the equipment is large, for example, when it is greater than a certain threshold, it means that the equipment is easy to form a cluster. The number of devices will be more, so the ratio of the first spectrum resource pool is larger; on the contrary, when the device density is low, for example, less than a certain threshold, the ratio of the second spectrum resource pool is larger. The base station may periodically acquire the number of devices within the current coverage area to obtain the density of the devices, and then adjust the number and proportion of spectrum resource elements in the first spectrum resource pool and the second spectrum resource pool.

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

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

Embodiment 7:

FIG. 13 is a schematic flowchart of a first spectrum resource allocation method provided by 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 traffic 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 devices will send attribute information such as their driving direction, position, and speed to the cluster head, and the cluster head will collect the cluster member information and report it to the base station in a package.

1202: Allocate a spectrum resource block including at least one spectrum resource element 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 block in the cluster Spectrum resource information.

After receiving the data packet sent by the cluster head device, the base station analyzes the data packet to obtain the cluster member information information, and allocate a spectrum resource block of a size corresponding to the cluster member information to the cluster head device from the first spectrum resource pool. 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 high, so in 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 relatively large, so the resources allocated for the cluster head of this cluster will be 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 only monitor the spectrum resource block corresponding to their cluster and use the idle spectrum resource elements 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 a spectrum resource block for each cluster head device from the first spectrum resource pool, and broadcasts to the cluster members through the cluster head device, and the cluster member devices only need to monitor the spectrum resource block, so the cluster member devices do not need to request from 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 devices, thereby reducing the network load of the base station. In addition, cluster member devices do not need to monitor the entire spectrum resource, but only need to monitor the cluster they belong to. The spectrum resource allocated by the cluster head device is enough, so the power consumption of the device can be reduced. In summary, the 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 at the same time.

In the implementation process of the present invention, there may be some devices that have not joined the cluster, then 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 that the equipment that has not joined the cluster Monitoring and using idle spectrum resource elements in the second spectrum resource pool to perform data transmission. This process can be performed while the base station broadcasts the attribute information of the cluster head device.

In this way, similar to the devices that join the cluster, the devices that do not join 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, thus reducing the network load of the base station while reducing the power consumption of the device.

FIG. 14 is a schematic diagram of spectrum resource allocation provided by an embodiment of the present invention.

In order to understand the present invention, the embodiment of the present invention also provides a schematic diagram of spectrum resource allocation obtained according to the above spectrum resource allocation method provided in the 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 of 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 provided by an embodiment of the present invention.

In addition, in order to improve the utilization rate of spectrum resources, the base station can timely adjust the size of the spectrum resource block allocated to the cluster 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 is relatively large, the base station should add new spectrum resources to the cluster in time. Therefore, the method, as shown in Figure 15, also includes:

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

Wherein, the cluster head device can periodically collect statistics on the usage of the spectrum resource blocks corresponding to the cluster and report it to the base station.

1302: Release a first number of spectrum resource elements from resource blocks allocated for the cluster head device when the spectrum resource utilization rate is lower than a first threshold.

Wherein, the first threshold may be a certain fixed value, for example, a value between 10%-20%, or a value that changes dynamically, for example, it may be adjusted 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 a specific quantity.

When the spectrum resource utilization rate of a certain cluster is low, a part of the spectrum resource elements needs to be released in time, for example, by counting the existing spectrum resource elements, the spectrum resource elements with low utilization rate are acquired and released.

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

Wherein, the second threshold may be a certain fixed value, such as a value between 80%-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 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 for 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 may periodically count the spectrum resource utilization of the cluster before performing The judgment of spectrum resource utilization rate, when the spectrum resource utilization rate is lower than a certain threshold, the cluster head device will report to the base station so that the base station can release unused spectrum resources 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 spectrum resource information of the updated spectrum resource block, and the cluster head device needs to broadcast the spectrum resource information of the updated 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 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. If there is a cluster head device not within the coverage range, delete the attribute information of the cluster head device not within the coverage range, designate a new cluster head device, and broadcast the attribute information of the new cluster head device.

Among them, when a non-cluster-head device selects a cluster-head device, it can use the cluster-head device with the closest distance to itself and the same driving direction as the target cluster-head device.

1502: When data transmission is required, monitor the 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 idle spectrum resource elements in the spectrum resource block to perform data transmission.
