detailed description

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

The clustering process of the device is specifically: the base station determines at least one device in the coverage as a cluster head device; and broadcasts attribute information of each cluster head device in the coverage to facilitate other devices to join the cluster.

Wherein, when the base station specifies the cluster head device, each device may randomly designate some devices as cluster head devices from all devices in the same driving direction in one or more regions where the device density is relatively large; the cluster head device may be The mobile device can also be a stationary device; it can be either a device located on the vehicle or a road side device (RSU).

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

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, other devices select the cluster head device that is closest to itself and has the same driving direction as the target cluster head device according to the position of the cluster head and the traveling direction, and join the cluster in which the target cluster head device is located.

In a specific implementation manner, in an implementation manner of the present invention, the device may be divided according to the density of the device in the coverage of the base station. For example, when the density of the device is large, for example, when the threshold is greater than a certain threshold, the device is easy to form a cluster and a cluster. The number of the first spectrum resource pool is larger; on the contrary, when the density of the device is small, for example, less than a certain threshold, the proportion of the second spectrum resource pool is larger. The base station can periodically acquire the number of devices in the current coverage to obtain the density of the device, and then adjust the quantity and 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 acquiring the density of the device, the utilization of the spectrum resources of the first spectrum resource pool and the second spectrum resource pool may be periodically calculated, when the first spectrum resource pool is used. When the utilization rate is often high, the number of spectrum resource particles of the first spectrum resource pool may be appropriately increased; instead, the number of spectrum resource particles of the second spectrum resource pool is appropriately increased.

Example 7

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

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

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

The cluster member information refers to the number of cluster members, the traffic volume of the entire cluster, and the location information of each cluster member.

In the process of establishing a cluster, the cluster member device sends its own information such as the direction, position and speed of the cluster head to the cluster head, and the cluster member information is collected by the cluster head and reported and reported to the base station.

1202: Allocating a spectrum resource block including at least one spectrum resource particle from each of the cluster head devices according to the cluster member information, so that the cluster head device broadcasts the spectrum resource block in a cluster. Spectrum resource information.

After receiving the data packet sent by the cluster head device, the base station parses the data packet to obtain a cluster member letter. Information, and allocate a spectrum resource block corresponding to the size of 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 cluster members of a certain cluster are mainly concentrated in a certain road section, and there are many intersections of the road section, the probability of collision of the vehicle is relatively large, so There may be more vehicles transmitting emergency signals in the cluster, and the data packets used to transmit the emergency signals are larger than the ordinary data packets, that is, the traffic is large, so the resources allocated for the cluster head of the cluster are relatively More.

After receiving the spectrum resource block allocated by the base station, the cluster head device broadcasts to the cluster member in time, so that the cluster member only listens to the spectrum resource block corresponding to the cluster, and uses the idle spectrum resource particles to perform data transmission.

The method for allocating spectrum resources provided by the present invention divides the spectrum resources into two parts: a first spectrum resource pool and a second spectrum resource pool, and divides the device into multiple clusters; on this basis, the base station can be based on the cluster members of each cluster. The information is that each cluster head device allocates a spectrum resource block from the first spectrum resource pool, and broadcasts to the cluster member through the cluster head device, and the cluster member device only listens to the spectrum resource block, so the cluster member device does not need to request the base station. The spectrum resource, the base station does not need to control the specific allocation of the resources of all the devices, and can reduce the number of interactions between the base station and the device, thereby reducing the network load of the base station. In addition, the cluster member device does not need to listen to the entire spectrum resource, and only needs to monitor the cluster in which it is located. The spectrum resources allocated by the cluster head device can be used, thereby reducing the power consumption of the device. In summary, the foregoing method for allocating spectrum resources provided by the embodiments of the present invention can reduce the network load of the base station while reducing the power consumption of the device.

In the implementation of the present invention, there may be cases where some devices are not added to the cluster, and the base station needs to broadcast the spectrum resource information of the second spectrum resource pool in the coverage to facilitate the devices that are not added to the cluster. Monitoring and utilizing the idle spectrum resource particles in the second spectrum resource pool for 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 device that joins the cluster, the device that does not join the cluster does not need to request the spectrum resource from the base station, and does not need to listen to the entire spectrum resource, and only needs to listen to the spectrum resource in the second spectrum resource pool, thereby reducing the network load of the base station. At the same time reduce 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 allocation of spectrum resources obtained by the foregoing spectrum resource allocation method according to an embodiment of the present invention, as shown in FIG. 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 two devices are respectively occupied. Spectrum resources.

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

In addition, in order to improve the utilization of the spectrum resources, the base station can adjust the size of the spectrum resource block allocated to the cluster according to the size of the cluster traffic. When the traffic in the cluster is 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 FIG. 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 report the utilization of the spectrum resource block corresponding to the cluster and report it to the base station.

1302: When the spectrum resource utilization is lower than the first threshold, release the first quantity of spectrum resource particles from the resource blocks allocated for the cluster head device.

The first threshold may be a fixed value, for example, a value of 10%-20%, or a dynamically changing value, for example, by continuously counting resource utilization.

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

When the spectrum resource utilization of a cluster is low, a part of the spectrum resource particles needs to be released in time. For example, by collecting the existing spectrum resource particles, the spectrum resource particles with lower utilization rate are obtained and released.

1303: Add a second quantity of spectrum resource particles to the cluster head device when the spectrum resource utilization is higher than a second threshold.

The second threshold may be a fixed value, for example, a value of 80%-90%, or a dynamically changing value, for example, by continuously counting resource utilization.

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

In addition, as an alternative to the foregoing

steps

1301 and 1303, in another implementation manner of the present invention, the cluster head device may periodically calculate the size of the spectrum resource utilization of the cluster. When the spectrum resource utilization rate is lower than a certain threshold, the cluster head device reports the base station to facilitate the base station to 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 the base station so that the base station adds 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 should 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 needs to delete the original cluster head information or add a new cluster head device in time and periodically broadcast. For example, the base station periodically monitors whether each of the cluster head devices that have been designated is within the coverage. If there is a cluster head device that is not in the coverage area, the attribute information of the cluster head device that is not in the coverage area is deleted, a new cluster head device is specified, and the attribute information of the new cluster head device is broadcasted.

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 broadcasted by the base station.

Wherein, when the cluster head device selects the cluster head device, the cluster head device that is closest to itself and has the same driving direction can be used as the target cluster head device.

1502: Listen to a spectrum resource block broadcast by the target cluster head device when data transmission is required, 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 blocks allocated by the cluster head device of the cluster in which it resides, without listening to the entire spectrum resource block.

1503: Perform data transmission by using idle spectrum resource particles in the spectrum resource block.
