Description

Transmission resource determining method, device and storage medium

Technical Field

The present application relates to the field of communications, and in particular, to a method and apparatus for determining transmission resources, and a storage medium.

Background

The conventional cellular network multiplexes time-frequency domain transmission resources in units of cells to improve the utilization rate of the transmission resources. For example, neighboring cells covered by a wireless network may use the same carrier frequency to increase spectrum resource utilization. However, the same-frequency networking may cause increased interference between cells, affecting network transmission performance.

At present, different cells share transmission resources in a time division or frequency division scheduling mode in a signal overlapping area so as to reduce interference among cells. However, the manner in which time-division or frequency-division scheduling is used may lead to a decrease in the transmission resource utilization.

The 6G wireless network also needs to enable thousands of industries to meet differentiated service performance requirements, and higher requirements are put forward on network performance indexes such as data rate, connection number, time delay and the like and networking flexibility. Thus, 6G networks will introduce new types of non-cellular network architecture. The honeycomb-free framework is based on the concept of centering on users, a plurality of distributed access devices and a central processing unit connected with all the access devices are deployed in a network, and the widely distributed access devices can realize high-level cooperation and cover the whole area through the centralized signal processing of the central processing unit. The terminal can access a plurality of specific access devices, and the frequency spectrum efficiency of the network is improved by utilizing the space macro diversity.

Conventional cellular networks multiplex time-frequency domain transmission resources in units of cells. At present, different cells share transmission resources in a time division or frequency division scheduling mode in a signal overlapping area so as to reduce interference among cells. However, the manner in which time-division or frequency-division scheduling is used may lead to a decrease in the transmission resource utilization.

The server may divide the plurality of first access devices to obtain a plurality of first candidate device clusters, where the first candidate device clusters include at least one first access device, and a distance between any two first candidate device clusters in the plurality of first candidate device clusters is greater than a preset distance threshold. Thus, a space exists between every two first candidate device clusters, and the interference degree between every two first candidate device clusters is small.

In this way, the interference degree among the plurality of first candidate device clusters is smaller, and each first candidate device cluster can use all transmission resources of the preset area, so that the utilization rate of the transmission resources can be improved on the premise of reducing the interference.

The server 101 and the terminal can perform wired/wireless communication. The central processing unit 102 may be in wired/wireless communication with the access devices. The access device may be in wired/wireless communication with the terminal.

It should be noted that, in the embodiment of the present application, the access device and the terminal are in the same preset area. The preset area is provided with a plurality of first access devices. A terminal may simultaneously access at least one access device for transmission of service data. An access device may transmit traffic data for at least one terminal.

Wherein the server 101 may be deployed with a resource configuration module. The resource allocation module may be configured to allocate radio transmission resources for access devices within a preset area. The resource allocation module can be connected with the central processing unit and the access equipment, and supports message interaction and parameter transfer between the resource allocation module and the access equipment.

The server may be a single physical server, or may be a server cluster including a plurality of servers. Alternatively, the server cluster may also be a distributed cluster. Alternatively, the server may be a cloud server. The embodiment of the application does not limit the specific implementation mode of the server.

The central processing unit 102 may be configured to implement baseband protocol processing functions to perform centralized processing of signals of connected devices. In an embodiment of the present application, the central processing unit 102 may be deployed separately, and the central processing unit 102 may also be deployed on a server.

It should be noted that, in the embodiment of the present application, the resource configuration module may be disposed on a separate server, or may be disposed on the central processing unit 102.

Access devices (e.g., access device 103 and access device 104) may be used for radio frequency signal transceiving processing, and traffic data of the terminal may be transmitted through the air interface.

Terminals (e.g., terminal 105, terminal 106, and terminal 107) may be a device having transceiving functionality. Terminals may be deployed on land, including indoors or outdoors, hand-held or vehicle-mounted; may also be deployed on the surface of water (e.g., a ship, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). The terminal includes a handheld device, an in-vehicle device, a wearable device, or a computing device with wireless communication capabilities.

In the embodiment of the application, the terminal can send the terminal information to the server or the access equipment. Embodiments of the present application will be described in detail below with reference to the drawings attached to the specification.

As shown in fig. 2, a method for determining transmission resources according to an embodiment of the present application includes:

s201, the server divides the plurality of first access devices to obtain a plurality of first candidate device clusters.

Wherein the first candidate device cluster comprises at least one first access device.

In the embodiment of the application, the distance between any two first candidate device clusters in the plurality of first candidate device clusters is larger than a preset distance threshold.

In the embodiment of the present application, the preset distance threshold is not limited. For example, the preset distance threshold may be 1000 meters. For another example, the preset distance threshold may be 500 meters. For another example, the preset distance threshold may be 300 meters.

In one possible implementation, the server may obtain location information for each of the plurality of first access devices. The server may divide at least one first access device having similar location information into the same first candidate device cluster according to the location information of each first access device, so as to obtain a plurality of first candidate device clusters.

In the embodiment of the present application, a plurality of access devices with similar locations are divided into the same first candidate device cluster, so that a certain distance interval exists between different first candidate device clusters. The farther the distance between different first candidate device clusters, the less the interference between different first candidate device clusters.

S202, the server acquires interference degrees between every two first candidate device clusters in the first candidate device clusters to obtain a plurality of target interference degrees.

One target interference degree corresponds to two first candidate device clusters, and the interference degree is used for indicating the interference degree between every two first candidate device clusters.

In one possible implementation, the server may receive an input instruction, where the input instruction is used to indicate a degree of interference between two first candidate device clusters of the plurality of first candidate device clusters. In response to the input instruction, the server may acquire interference degrees between every two first candidate device clusters in the plurality of first candidate device clusters, so as to obtain a plurality of target interference degrees.

S203, the server determines at least one target device cluster and at least one second candidate device cluster according to each target interference degree.

In one possible implementation, the server stores a preset interference threshold. For each target interference level, the server may determine whether the target interference level is greater than a preset interference threshold.

It should be noted that, in the embodiment of the present application, the preset interference threshold is not limited. For example, the preset interference threshold may be 50%. For another example, the preset interference threshold may be 70%. For another example, the preset interference threshold may be 30%.

In one possible design, if the target interference level is greater than the preset interference threshold, the server may combine the two first candidate device clusters corresponding to the target interference level to obtain a target device cluster, so as to determine at least one target device cluster.

For example, if the two first candidate device clusters corresponding to the target interference level include: the first candidate device cluster a and the first candidate device cluster B, the target device cluster includes: all first access devices in the first candidate device cluster a and all first access devices in the first candidate device cluster B.

In the embodiment of the present application, the server merges two first candidate device clusters with higher interference into one target device cluster, so that the interference between the device clusters can be reduced.

In the embodiment of the present application, the second candidate device cluster is any device cluster except at least one target device cluster in the plurality of first candidate device clusters.

Illustratively, provided that the plurality of first candidate device clusters includes: the first candidate device cluster a, the first candidate device cluster B, the first candidate device cluster C, the first candidate device cluster D, the first candidate device cluster E, the first candidate device cluster F, and the at least one target device cluster includes: the first candidate device cluster a, the first candidate device cluster B, the first candidate device cluster D, the first candidate device cluster E, then the at least one second candidate device comprises: a first candidate device cluster C, a first candidate device cluster F.

S204, the server determines that each target device cluster and each second candidate device cluster respectively multiplex transmission resources of a preset area.

In one possible design, the transmission resources include: air interface wireless transmission resources of time domain, frequency domain and code domain.

It should be noted that, in the embodiment of the present application, the server is deployed with a resource configuration module. The resource allocation module may allocate transmission resources for the access device in the preset area, so that the access device may use the transmission resources to transmit service data of the terminal.

In one possible implementation, the server may determine that each target device cluster and each second candidate device cluster respectively multiplex transmission resources of the preset area.

That is, each target device cluster may multiplex transmission resources of a preset area, and each second candidate device cluster may multiplex transmission resources of a preset area.

For example, if the transmission resources of the preset area include a frequency of 10 mhz, the at least one target device cluster includes: a target device cluster 1 and a target device cluster 2, wherein the target device cluster 1 includes: a first candidate device cluster a and a first candidate device cluster B, the target device cluster 2 including: a first candidate device cluster D and a first candidate device cluster E; the at least one second candidate device comprises: a first candidate device cluster C and a first candidate device cluster F. The target device cluster 1 may transmit traffic data of the terminal using a frequency of 10 mhz, the target device cluster 2 may transmit traffic data of the terminal using a frequency of 10 mhz, the first candidate device cluster C may transmit traffic data of the terminal using a frequency of 10 mhz, and the first candidate device cluster F may transmit traffic data of the terminal using a frequency of 10 mhz.

In the embodiment of the application, at least one first access device in each target device cluster and at least one first access device in each second candidate device cluster share transmission resources of a preset area. Different first access devices in the target device cluster and the second candidate device cluster may use transmission resources that are orthogonal in time domain, frequency domain, and code domain.

In the embodiment of the present application, the interference between the device clusters is small, and the same transmission resource can be used. Different first access devices in each device cluster use transmission resources orthogonal to time domain, frequency domain and code domain, so that interference among access devices can be reduced.

In this embodiment, the server first divides, according to the location information of each access device, multiple access devices with similar locations into the same first candidate device cluster, so that a certain distance interval exists between different first candidate device clusters, and inter-cluster interference is reduced. And secondly, determining target interference degrees corresponding to any two first candidate device clusters, and further dividing the first candidate device clusters into a target device cluster and at least one second candidate device cluster according to the target interference degrees, so that the interference among different device clusters is smaller. On the basis, determining that each target equipment cluster and each second candidate equipment cluster respectively multiplex transmission resources of a preset area, thereby improving the utilization rate of the transmission resources while reducing interference. In some embodiments, as shown in fig. 3, before the server divides the plurality of first access devices to obtain the plurality of first candidate device clusters (S201), the method for determining transmission resources may further include:

S301, the server acquires position information of each of a plurality of first access devices.

In one possible implementation, for each first access device, the first access device may determine location information of the first access device by way of positioning. The first access device may send location information of the first access device to the server. The server may receive location information from the first access device to obtain location information of the first access device.

In the embodiment of the application, the server can receive the position information from each first access device to acquire the position information of each first access device in the plurality of first access devices.

In the embodiment of the present application, the server divides the plurality of first access devices to obtain a plurality of first candidate device clusters (S201), and may further include S302.

S302, the server inputs the position information of the plurality of first access devices into a device classification model to obtain a plurality of first candidate device clusters.

The distance between any two first access devices in the first candidate device cluster is smaller than a preset distance threshold.

In one possible implementation manner, the server may input the location information of the plurality of first access devices into the device classification model, and obtain a plurality of first candidate device clusters through the distance between every two first access devices.

It will be appreciated that the server may obtain location information for each of the plurality of first access devices. The server can input the position information of the plurality of first access devices into the device classification model to obtain a plurality of first candidate device clusters, wherein the distance between any two first access devices in the first candidate device clusters is smaller than a preset distance threshold. In this way, the accuracy of dividing the plurality of first candidate access device clusters can be improved.

In some embodiments, the server obtains interference degrees between every two first candidate device clusters in the plurality of first candidate device clusters to obtain a plurality of target interference degrees (S202), and may further include: for the plurality of first candidate device clusters, the server can determine the interference degree between every two first candidate device clusters in the plurality of first candidate device clusters according to the target operation so as to obtain a plurality of target interference degrees.

In an embodiment of the present application, as shown in fig. 4, the target operation may include the following steps: S401-S404.

S401, the server acquires first test information of each second access device in the first device cluster and second test information of each third access device in the second device cluster.

The first device cluster and the second device cluster are device clusters in the first candidate device clusters. The second access device is any access device in the first device cluster, and the third access device is any access device in the second device cluster.

In one possible implementation, the server may send a first test instruction to each second access device, where the first test instruction is used to instruct to detect, in a preset period of time, an interference signal strength of each third access device to the second access device. The server may receive first test information from each second access device, the first test information including an interference signal strength of each third access device to the second access device.

Similarly, the server may send a second test instruction to each third access device, where the second test instruction is used to indicate the interference signal strength of each second access device to the third access device in a preset period. The server may receive second test information from each third access device, the second test information including interference signal strength of each second access device to the third access device.

Wherein the test instruction comprises: the method comprises the steps of testing signals, resource position information occupied by the testing signals, identification information of access equipment and a preset period. One access device corresponds to one identification information, one access device corresponds to one test signal, and one test signal corresponds to one time-frequency resource location information. The preset period is a period in which the traffic volume of the terminals is less than a preset traffic volume threshold, or the number of terminals is less than a preset number threshold.

It should be noted that, in the embodiment of the present application, the resource location information occupied by the test signal may be time-frequency resource location information. By indicating each access device to transmit a corresponding test signal, the interference relationship between multiple access devices can be dynamically obtained; and the transmission resource allocation modes of a plurality of access devices can be determined according to the interference relation, so that the maximum resource utilization rate is realized while the interference is reduced. In addition, the test signals of different access devices are orthogonal in time domain or frequency domain, and the time-frequency resource position information occupied by the test signals of each access device corresponds to the identification information of each access device one by one, so that the interference degree between the test signals transmitted by different access devices can be avoided, and the detection quality of each test signal is ensured. The access device is instructed to transmit the test signal in the preset time period, and the preset time period is a time period with smaller traffic or user number, so that the performance of the access device for transmitting the service data can be prevented from being reduced, and the situation that the access device transmits the test signal for a long time to increase energy consumption and processing cost can be avoided.

The following describes, in connection with a specific embodiment, the method for acquiring, by a server, first test information of each second access device in the first device cluster and second test information of each third access device in the second device cluster.

For example, the server may send test instructions to each second access device and each third access device. And each second access device and each third access device transmit respective corresponding test signals in a preset period according to the test instruction. The fourth access device may detect the time-frequency position occupied by the test signal corresponding to the other devices, and determine the signal strength of the test signal of the other access devices, so as to obtain the interference signal strength (i.e. test information) of each access device in the other access devices to the fourth access device, where the fourth access device may be any access device in the first device cluster and the second device cluster, and the other access devices are access devices in the first device cluster and the second device cluster except the fourth access device. The fourth access device may send test information to the server. The server may receive test information from the fourth access device. For the description of obtaining the first test information of each second access device and the second test information of each third access device, reference may be made to the description of the fourth access device above, which is not repeated here.
