detailed description

In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

First, a brief introduction to the nouns involved in the embodiments of this application:

A heterogeneous network is a network composed of two or more different networks. Two or more different networks use different wireless technologies. The networks are independent of each other and do not perform information exchange or resource coordination. In one example, heterogeneous networks include wireless cellular networks such as LTE and wireless ad hoc networks. Wireless ad hoc network is a temporary autonomous network including multiple communication nodes. The nodes in the network are all equal, and each communication node is equipped with a wireless transceiver, which has the functions of sending, forwarding and receiving, so any two nodes in the network can communicate through a direct link or a multi-hop link. Compared with traditional cellular networks, wireless ad hoc networks do not need to rely on infrastructure, and have the advantages of flexible and simple networking, high network reliability, and large coverage. The wireless cellular network includes two modes of TDD and FDD. In TDD-LTE, the uplink and downlink transmissions between the cellular base station and the terminal use the same working frequency band, and the uplink and downlink transmissions occur in different subframes. In FDD-LTE, different working frequency bands are used for the uplink and downlink transmission between the cellular base station and the terminal, and only uplink transmission and downlink transmission are performed on each working frequency band. Please refer to FIG. 1, in the heterogeneous network 100, there is a wireless broadband cellular network base station 110 corresponding to the wireless cellular network, at least two wireless ad hoc network nodes 120 and a terminal 130, wherein the terminal 130 can be implemented as a wireless ad hoc network network node, to join the wireless ad hoc network network, or, the terminal can receive the signal sent by the wireless broadband cellular network base station 110, and realize the communication function through the wireless broadband cellular network base station 110, that is, at this time, the terminal 130 is located in the heterogeneous network 100 in.

In the wireless broadband LTE cellular network or the wireless ad hoc network using LTE technology, the working frequency band includes two parts: the guard frequency band and the transmission frequency band, and the transmission frequency band is divided into multiple subcarriers. Please refer to Figure 2 to divide the 10MHz working frequency band 200 into 600 When there are subcarriers 201, the bandwidth of each subcarrier 201 is 15kHz. In a time slot of 0.5 ms, a time-frequency resource composed of 7 Orthogonal Frequency Division Multiplexing (OFDM) symbols 202 and 12 subcarriers 201 is called a physical resource block (Physical Resource Block, PRB) ), that is, the unit time-frequency resource 203 . The unit time-frequency resource 203 is the smallest unit of frequency-domain resource allocation, and each data transmission needs to use one or more unit time-frequency resources.

In the heterogeneous network as shown in FIG. 1 , since the networks are independent of each other, when a communication interaction such as data transmission occurs between the terminal and the heterogeneous network, interference is likely to occur, thereby reducing the efficiency of data transmission. Therefore, it is necessary to determine frequency domain resources used for different types of network communications.

FIG. 3 shows a flow chart of a method for dividing frequency domain resources provided by an exemplary embodiment of the present application. Taking the application of the method in computer equipment as an example for illustration, the method includes:

Step 301, determining a first preset working frequency band corresponding to a first network, where the first network includes a wireless broadband cellular network.

The subject of execution of this application is a computer with computing functions. Optionally, before determining the first preset working frequency band, the computer first acquires the network status of the first network. Wherein, the network state of the first network includes a first preset working frequency band corresponding to the first network, that is, a frequency range occupied by the terminal when the first network communicates. The network status of the first network further includes at least one of the network identifier of the first network, the signal strength of the first network under preset conditions, and the transmission capability of the first network under preset conditions.

In the embodiment of the present application, the first network corresponds to the wireless broadband cellular network. In the wireless broadband cellular network, the transmission power of its uplink transmission is relatively small, which will not cause terminals transmitted in the wireless ad hoc network. Therefore, in the embodiment of the present application, the first preset working frequency band corresponding to the first network is The preset working frequency band for the downlink transmission of the wireless broadband cellular network.

In this application, the first network may also be a different type of wireless network with the same properties as the wireless broadband cellular network, that is, a network corresponding to a signal sending base station. This application does not limit the specific form of the first network.

Step 302, determining a second preset working frequency band corresponding to a second network, where the second network is a different type of network from the first network, and the second network includes a wireless ad hoc network.

As mentioned above, before determining the second preset working frequency band, the computer acquires the network status of the second network. Wherein, the network status of the second network includes a second preset working frequency band corresponding to the second network, that is, a frequency range occupied by the terminal when the second network communicates. The network state of the second network further includes at least one of the network identifier of the second network, the signal strength of the second network under preset conditions, and the transmission capability of the second network under preset conditions.

In the embodiment of the present application, the second network corresponds to a wireless ad hoc network. Wireless ad hoc network is a temporary autonomous network including multiple communication nodes. The nodes in the network are all equal, and each communication node is equipped with a wireless transceiver, which has the functions of sending, forwarding and receiving, so any two nodes in the network can communicate through a direct link or a multi-hop link. Compared with traditional cellular networks, wireless ad hoc networks do not need to rely on infrastructure, and have the advantages of flexible and simple networking, high network reliability, and large coverage.

In this application, the first network may also be a different type of wireless network with the same properties as the wireless broadband cellular network, that is, a network corresponding to at least two wireless nodes, and this application does not limit the specific form of the second network.

Step 303: Based on the frequency domain difference between the first preset working frequency band and the second preset working frequency band, divide the first frequency domain resource and the second frequency domain resource, wherein the first frequency domain resource is for downlink data through the first network The frequency domain resource occupied during transmission, the second frequency domain resource is the frequency domain resource occupied during data transmission through the second network.

As mentioned above, after the computer device acquires the first preset frequency band and the second preset frequency band, the first preset working frequency band can be determined by comparing the first preset working frequency band with the second preset working frequency band The difference between the frequency band and the second preset working frequency band. Optionally, in this application, only the difference degree of frequency domain resources is considered to obtain the frequency band difference between the first preset working frequency band and the second preset working frequency band, that is, the overlap degree of unit time-frequency resources in the frequency band. In one example, please refer to FIG. 4 , the first preset working frequency band 401 includes 50 unit time-frequency resources, the second preset working frequency band 402 includes 50 unit time-frequency resources, and in the first preset working frequency band The frequency of the unit time-frequency resource in 401 corresponds to the frequency of the unit time-frequency resource in the second preset working frequency band 402. At this time, the first preset working frequency band 401 and the second preset working frequency band 402 completely overlap; In another example, please refer to FIG. 5 , the first preset working frequency band 501 includes A+B unit time-frequency resources, the second preset working frequency band 502 includes B+C unit time-frequency resources, and B+ C=50. And the B unit time-frequency resources in the first preset working frequency band 501 overlap with the B unit time-frequency resources in the second preset working frequency band 502 . That is, the first preset working frequency band 501 and the second preset working frequency band 502 have repeated B unit time-frequency resources. At this time, the first preset working frequency band 501 and the second preset working frequency band 502 partially overlap; In another example, please refer to FIG. 6, the first preset working frequency band 601 includes 50 unit time-frequency resources, the second preset working frequency band 602 includes 50 unit time-frequency resources, and the first preset working frequency band 601 The frequency of any unit time-frequency resource in the second preset working frequency band 602 is not correspondingly equal to any unit time-frequency resource in the second preset working frequency band 602, that is, the first preset working frequency band 601 and the second preset working frequency band 602 are completely do not coincide.

As mentioned above, the case where the first preset working frequency band completely overlaps with the second preset working frequency band can be regarded as the first coupling situation, and the situation where the first preset working frequency band partially overlaps with the second preset working frequency band can be regarded as In the second coupling situation, the situation that the first preset working frequency band does not overlap with the second preset working frequency band is taken as the third coupling situation. In one example, the process is to determine the frequency domain difference between the first preset working frequency band and the second preset working frequency band based on the coupling between the first preset working flat band and the second preset working frequency band, and then divide The process of the first frequency domain resource and the second frequency domain resource.

After determining the frequency domain difference between the first preset working frequency band and the second preset working frequency band, the computer device can allocate the first time-frequency resource and the second time-frequency resource according to the frequency band difference, wherein the first time-frequency The frequency resources are allocated frequency domain resources for the first network to perform downlink data transmission, and the second time-frequency resources are allocated frequency domain resources for the second network to perform data transmission.

In the embodiment of this application, when the wireless broadband cellular network base station has the ability to exchange information with the nodes in the wireless ad hoc network, the computer equipment with computing power can be implemented as a wireless broadband cellular network base station, and the base station directly performs frequency domain Calculation and configuration of resource allocation methods; when the wireless broadband cellular network base station and the nodes in the wireless ad hoc network cannot communicate, that is, when they do not have the ability to exchange information, the computer equipment with computing power is implemented as a third-party computer equipment, through After the third-party computer equipment calculates and configures the allocation method of frequency domain resources, it sends the configuration results to the base stations of the wireless broadband cellular network and the nodes of the wireless ad hoc network for corresponding division of frequency domain resources.

To sum up, the method provided in this embodiment determines the preset operating frequency bands corresponding to the first network and the second network respectively, and determines the difference between the two in the operating frequency domain, and determines the frequency band for the first network. Different resources are allocated for the downlink data transmission of the second network and the data transmission of the second network. According to the different situations of the two networks, by coordinating frequency domain resource allocation, co-channel interference is avoided or reduced, network transmission performance is improved, and service experience is improved.

As mentioned above, in some embodiments of the present application, the differences between the first preset working frequency band and the second preset working frequency band include the following three types: the first preset working frequency band completely overlaps with the second preset working frequency band, The first preset working frequency band does not completely overlap with the second preset working frequency band and the first preset working frequency band does not completely overlap with the second preset working frequency band. Corresponding to the three situations, the first frequency domain resource corresponding to the first network and the second frequency domain resource corresponding to the second network will change. At the same time, before allocating frequency domain resources, the area covered by the first network will be divided according to the interference between the first network and the second network, so as to provide different network node locations for different network nodes. frequency domain resources. FIG. 7 shows a flow chart of a method for dividing frequency domain resources provided by an exemplary embodiment of the present application. The application of the method in computer equipment is used as an example for illustration. The method includes:

Step 701, determine the receiving performance of the second network node.

In the embodiment of the present application, the first network is the wireless broadband cellular network, and the second network is the wireless ad hoc network. Correspondingly, the second network includes at least two network nodes. In the embodiment of the present application, the foregoing node is the second network node. Since the first network and the second network are in an overlapping state, the second network node is located within the coverage area of the first network. In the embodiment of the present application, the nodes in the second network correspond to receiving capabilities. The ability of nodes in the second network to receive signals is affected by the first network. Therefore, in the embodiment of the present application, the receiving performance of the second network node is the SINR value of the second network node.

Step 702, when the SINR corresponding to the second network node is not greater than the SINR threshold, determine that the second network node belongs to the first coverage area.

The signal-to-interference-noise ratio is the ratio of the sum of signal and interference noise in the system. In the embodiment of this application, the SINR value is the second network node, that is, the signal received by the node in the wireless ad hoc network from other nodes, and the interference received by the node from the base station of the wireless broadband cellular network ratio of the signal. In the embodiment of the present application, for the nodes within the radiation area of the base station of the wireless broadband cellular network and belonging to the wireless ad hoc network, the signal-to-interference-noise ratio value is determined by setting an ideal node. In one example, an ideal node with preset signal strength is set at a preset distance from the node in the wireless ad hoc network, and the signal-to-interference-noise ratio value of the node in the wireless ad hoc network is detected to determine the second network node Whether the corresponding SINR value is greater than the SINR threshold. When the SINR value corresponding to the second network node is not greater than the SINR threshold value, it means that the second network node is greatly affected by the wireless broadband cellular network, and at this time, the second network node belongs to the first coverage area .

It should be noted that, including the SINR threshold, various "thresholds" appear in this application. In the embodiments involved in the present application, the threshold may be a value pre-stored in the computer device and invoked during program execution, or a value temporarily set during execution of the corresponding program. This application does not limit the specific way of setting the threshold.

Step 703: Determine the first coverage area based on the second network nodes belonging to the first coverage area.

In the embodiment of the present application, through the method in step 702, all nodes whose SINR value is not greater than the SINR threshold value are classified into the first coverage area.

Step 704: Determine the second coverage area that does not overlap with the first coverage area within the coverage area of the first network.

In the embodiment of the present application, within the coverage area of the first network, the first coverage area and the second coverage area do not overlap with each other. In an example, within the coverage area of the first network, after the first coverage area is determined, the remaining part is divided according to preset rules stored in the computer device, and 50% of the remaining part is divided into the second coverage area; In another example, within the coverage area of the first network, all locations except the first coverage area are the second coverage area. In the embodiment of the present application, description is made by taking as an example that in the coverage area of the first network, all locations except the first coverage area are the second coverage area. Since in the embodiment of the present application, the number of wireless broadband cellular network base stations is 1, and the signal strength of the wireless broadband cellular network base stations weakens with the distance from the signal, so as shown in FIG. 8, corresponding to the wireless broadband cellular network base station 800, there are A first coverage area 801 and a second coverage area 802, wherein the first coverage area 801 is a circle with the wireless broadband cellular network base station 800 as the center, and the second coverage area 802 is a circle outside it. Both the first coverage area 801 and the second coverage area 802 include at least one wireless ad hoc network node 810 .

Step 705, determine a first preset working frequency band corresponding to the first network.

Step 706, determining a second preset working frequency band corresponding to the second network.

Steps 705 to 706 are corresponding to steps 301 to 302, and will not be repeated here.

Step 707, when the first preset working frequency band completely overlaps with the second preset working frequency band, determine a throughput change threshold.

In an example of the embodiment of the present application, the first preset working frequency band and the second preset working frequency band are completely overlapped.

In the embodiment of the present application, the first network, that is, the wireless broadband cellular network corresponds to the first network throughput, and all the nodes of the wireless ad hoc network correspond to the node throughput. Corresponding to the node throughput, the first coverage area has the average throughput of the first coverage area, the second coverage area has the average throughput of the second coverage area, and the nodes within the scope of the wireless ad hoc network also correspond to the total average throughput of the nodes Throughput, that is, the throughput of the second network.

In the computer device, there is a first network throughput threshold corresponding to the first network throughput. In one example, the first network throughput threshold may indicate a throughput change ratio, and in another example, the first network throughput threshold may be a current throughput change value. The present application makes no limitation on the first network throughput threshold.

Step 708, allocate m ₁ unit time-frequency resources to the first frequency-domain resource.

Step 709, when m ₁ +1 unit time-frequency resources are allocated to the first frequency domain resource, and the first network throughput change is greater than the throughput change threshold, determine that the number of unit time-frequency resources in the first frequency domain resource is n ₁ -m ₁ .

In the embodiment of the present application, n1 is the number of unit time-frequency resources where the first preset working frequency band overlaps with the second preset working frequency band. Since the first preset working frequency band completely overlaps with the second preset working frequency band, n ₁ is the number of unit time-frequency resources in the first preset working frequency band, or the unit time-frequency resources in the second preset working frequency band quantity.

In the embodiment of the present application, when the number of unit time-frequency resources allocated to the first frequency domain resource is too large, the throughput of the first network corresponding to the wireless broadband cellular network will decrease, and the variation of the decrease is greater than the variation of the throughput. When the threshold is reached, it is determined that the number of unit time-frequency resources in the first frequency-domain resources is n ₁ -m ₁ .

Step 710, allocate k ₁ unit time-frequency resources to the second frequency domain resources.

After it is determined that the number of unit time-frequency resources in the first frequency domain resource is n ₁ -m ₁ , configuration of unit time-frequency resources in the second frequency domain resource is performed. In an example, m1 unit time _- frequency resources may be directly configured as the number of unit time-frequency resources in the second frequency domain resource. However, in order to ensure signal transmission efficiency in the second frequency domain resources, _m1 frequency domain resources are selected.

Step 711, when k ₁ +1 unit time-frequency resources are allocated to the second frequency domain resource and the throughput of the first coverage area remains unchanged, determine that k ₁ unit time-frequency resources in the second frequency domain resource.

In the embodiment of the present application, after the unit time-frequency resources are configured, the throughput corresponding to the first coverage area remains unchanged, that is, the communication in the first coverage area is not affected by the configuration of time-frequency resources. At this time, That is, it is determined that there are k ₁ unit time-frequency resources in the second frequency-domain resources.

In another embodiment of the present application, the first preset working frequency band partially overlaps with the second preset working frequency band.

In the embodiment of the present application, k ₁ <m ₁ <n ₁ , and k ₁ , n ₁ , and m ₁ are all positive integers.

Step 712, when the first preset working frequency band partially overlaps with the second preset working frequency band, determine the non-overlapping ratio of n ₂ and the unit time-frequency resource quantity of the second preset working frequency band.

The non-overlapping ratio is the ratio of the unit time-frequency resource quantity in the overlapping part to the total unit time-frequency resource quantity on the second preset working frequency band corresponding to the wireless ad hoc network. In an example, the total number of unit time-frequency resources on the second preset working frequency band is 100, and the number of unit time-frequency resources in the overlapping part is 10, then the non-overlapping ratio is 10/100=0.1.

Step 713, when the non-overlapping ratio is not lower than the frequency-domain resource ratio threshold, allocate m2 unit time-frequency resources to the first frequency-domain resource.

In the embodiment of the present application, the frequency domain resource proportion threshold is correspondingly stored in the computer device. The frequency domain resource ratio threshold is the threshold corresponding to the non-overlapping ratio. When the non-overlapping ratio is higher than or equal to the resource ratio threshold, execute steps 713 to 717. When the non-overlapping ratio is lower than the resource ratio threshold, execute steps 718 to 717. Step 719.

In the embodiment of the present application, m ₂ is the unit allocated to the first frequency domain resource when the corresponding first preset working frequency band partially overlaps with the second preset working frequency band, and the non-overlapping 1 is not lower than the frequency domain resource ratio threshold The number of time-frequency resources.

Step 714: When m ₂ -1 unit time-frequency resources are allocated to the first frequency-domain resource and the throughput of the first network changes, determine that the number of unit time-frequency resources in the first frequency-domain resource is m ₂ .

In this embodiment of the application, as described in step 709, the first network throughput is used to determine the number of unit time-frequency resources in the first frequency domain resource. In this embodiment of the application, the number of unit time-frequency resources in the first frequency domain resource The number of unit time-frequency resources is 2.

Step 715, determine that the number of unit time-frequency resources in the second frequency domain resources is n ₂ +r1, wherein the number of available unit time-frequency resources in the first coverage area is n ₂ , and the number of available unit time-frequency resources in the second coverage area The number of time-frequency resources is n ₂ +r1.

In the embodiment of the present application, since part of the unit time-frequency resources in the first coverage area are affected by the wireless broadband cellular network, the available unit time-frequency resources are relatively small, while the unit time-frequency resources in the second coverage area are affected by the wireless broadband cellular network. The impact of the broadband network is less, and the number of available unit time-frequency resources is large, so the number of unit time-frequency resources allocated to the second frequency domain resources of the wireless ad hoc network is n ₂ +r1 in total, wherein the first coverage area The number of available unit time-frequency resources in the second coverage area is n ₂ , and the number of available unit time-frequency resources in the second coverage area is n ₂ +r1 .

It should be noted that, in the embodiment of the present application, m ₂ , n ₂ and r1 are all positive integers.

Step 716, when m ₂ -r ₂ unit time-frequency resources are allocated to the first frequency domain resources, the throughput of the first network does not change, and m ₂ -r ₂ -1 unit time-frequency resources are allocated to the first frequency domain resources , when the throughput of the first network changes, it is determined that the number of unit time-frequency resources in the first frequency-domain resources is m ₂ -r ₂ .

Step 717, determine that the number of unit time-frequency resources in the second frequency domain resource is n ₂ +r1, wherein the number of available unit time-frequency resources in the first coverage area is n ₂ , and the number of unit time-frequency resources in the second coverage area The number of available unit time-frequency resources is n ₂ +r1, and r ₂ is a positive integer.

Steps 716 to 717 are the process of assigning the number of unit time-frequency resources in the first frequency domain resource and the second frequency domain resource when the number of correspondingly configured unit time-frequency resources changes but the throughput of the first network does not change.

Step 718, when the non-overlapping ratio is lower than the frequency-domain resource ratio threshold, determine a set of unit time-frequency resource quantities.

Step 719: Determine the unit time-frequency resource quantity in the first frequency domain resource and the unit time-frequency resource quantity in the second frequency domain resource according to the set of unit time-frequency resource quantity.

As described in steps 718 to 719, when the non-overlapping ratio is lower than the frequency-domain resource ratio threshold, it indicates that the non-overlapping ratio between the first preset working frequency band and the second preset working frequency band is small, and the time available for allocation Video resources are also limited. At this time, a set of unit time-frequency resource quantities corresponding to the first frequency domain resource and the second frequency domain resource will be determined, and then the unit time-frequency resource quantity in the first frequency domain resource and the second frequency domain resource will be determined.

Step 720, when the first preset working frequency band does not overlap with the second preset working frequency band, determine the first preset working frequency band as the first frequency domain resource, and determine the second preset working frequency band as the second frequency domain resource resource.

In the embodiment of the present application, when the first preset working frequency band does not overlap with the second preset working frequency band at all, it is difficult for the communication between the first network and the second network to interfere with each other during the communication process, so the first The frequency domain resource will directly correspond to the first preset working frequency band, and the second frequency domain resource will directly correspond to the second preset working frequency band.

To sum up, the method provided in this embodiment determines the preset operating frequency bands corresponding to the first network and the second network respectively, and determines the difference between the two in the operating frequency domain, and determines the frequency band for the first network. Different resources are allocated for the downlink data transmission of the second network and the data transmission of the second network. According to the different situations of the two networks, by coordinating frequency domain resource allocation, co-channel interference is avoided or reduced, network transmission performance is improved, and service experience is improved.

The method provided in this embodiment divides the coverage area of the first network according to the receiving performance of the nodes of the second network, and sets different frequency domain resources corresponding to different working frequency domain differences and different coverage area conditions after division. The allocation method further improves the data transmission performance in the case of corresponding to different node states.

Fig. 9 shows a schematic diagram of the process of a method for dividing frequency domain resources provided by an exemplary embodiment of the present application. Please refer to Fig. 9, the process includes:

Step 901, according to the receiving performance of the wireless ad hoc network nodes at different locations, the coverage area of the wireless broadband cellular network base station is divided into the first coverage area and the second coverage area, and the wireless ad hoc network nodes are divided into the first coverage area node and the second coverage area Two coverage area nodes.

This process is the process of dividing the coverage area of the first network. After the division of the first coverage area and the second coverage area, the network nodes corresponding to the second network are also correspondingly summarized into the coverage area corresponding to itself. area.

In an example, the method of dividing the first coverage area and the second coverage area according to the receiving performance of the wireless ad hoc network nodes at different locations is as follows:

Suppose there are two wireless ad hoc network nodes A and B, node A is the sending node, and node B is the receiving node. The transmission distance between the two nodes is the preset transmission distance, and the transmission power of node A is the maximum transmission power. On the same channel, when Node B receives the transmission signal of Node A and the interference signal of the cellular network base station at the same time, the received SINR value of Node B is not higher than the preset SINR threshold, and Node B that meets the above conditions The set of locations is the first coverage area, and other areas within the coverage area of the cellular network base station are the second coverage area.

Step 902, if the downlink transmission of the wireless broadband cellular network and the wireless ad hoc network use the same working frequency band, divide the frequency domain resources of the working frequency band into a first frequency domain resource set and a second frequency domain resource set according to the PRB ratio.

The "first frequency domain resource set" in this process embodiment corresponds to the "second frequency domain resource" in the preceding embodiments, and the "second frequency domain resource set" in this process embodiment corresponds to the preceding embodiment "First Frequency Domain Resource". Steps 902 to 903 correspond to the division process of the first frequency domain resource and the second frequency domain resource when the first preset working frequency band and the second preset working frequency band are completely overlapped.

Step 903, the downlink transmission in the wireless broadband cellular network uses the second set of frequency domain resources, the transmission between the nodes in the first coverage area, and the transmission with the nodes in the second coverage area use the first set of frequency domain resources, and the second Transmission between nodes in the coverage area uses all frequency domain resources of the operating frequency band.

In this case, as in the following example:

①If the number of PRBs in the second frequency domain resource set is N (N>0) PRBs less than the number of PRBs in the entire working frequency band, the throughput of the cellular network does not decrease, but when there are N+1 PRBs less, the throughput of the cellular network Starting to decrease, the first frequency-domain resource set includes N PRBs. Further, assuming that there is a PRB number M<N, if the average throughput of the first coverage area node is the same when the number of PRBs is M and M+1, then the first frequency domain resource set includes M PRBs.

② If the number of PRBs in the second frequency domain resource set is one PRB less than the number of PRBs in the entire working frequency band, the throughput of the cellular network starts to decrease, and a throughput ratio threshold is preset. When the number of PRBs in the second frequency domain resource set is N PRBs less than the number of PRBs in the entire working frequency band, the throughput reduction ratio does not exceed the preset throughput ratio threshold, but when there are N+1 PRBs less, the throughput reduction ratio Start to exceed the preset throughput ratio threshold, the first frequency domain resource set includes N PRBs. Further, assuming that there is a PRB number M<N, if the average throughput of the first coverage area node is the same when the number of PRBs is M and M+1, then the first frequency domain resource set includes M PRBs.

Step 904, if the working frequency bands used by the wireless broadband cellular network and the wireless ad hoc network partially overlap, determine the allocation of frequency domain resources for the overlapping part according to the network throughput of the wireless cellular network and the average throughput of nodes in the first coverage area under different circumstances .

Steps 904 to 905 correspond to the division process of the first frequency domain resource and the second frequency domain resource when the first preset working frequency band partially overlaps with the second preset working frequency band.

Step 905, the downlink transmission in the wireless broadband cellular network uses non-overlapping frequency domain resources and all/partially overlapping frequency domain resources on its working frequency band, transmission between nodes in the first coverage area, and transmission between nodes in the second coverage area The transmission between nodes uses the non-overlapping part of the frequency domain resources on the working frequency band of the wireless ad hoc network and the frequency domain resources of all/partial overlapping parts, and the transmission between the nodes in the second coverage area uses all the frequency domain resources on the working frequency band of the wireless ad hoc network frequency domain resources.

In this case, as in the following example:

① Assuming that the number of PRBs in the non-overlapping part of the working frequency band of the wireless ad hoc network is N, if the average throughput of the nodes in the first coverage area is the same when the number of PRBs is N and N+1, the downlink transmission in the wireless broadband cellular network uses cellular The frequency domain resources on the working frequency band of the network, the transmission between the nodes in the first coverage area, and the transmission with the nodes in the second coverage area use the frequency domain resources of the non-overlapping part of the working frequency band of the wireless ad hoc network, and the nodes in the second coverage area The transmission between uses all the frequency domain resources of the working frequency band of the wireless ad hoc network.

②Assuming that the number of PRBs in the non-overlapping part of the wireless ad hoc network operating frequency band is N, the number of PRBs in the overlapping part is R, and the number of PRBs in the non-overlapping part of the wireless broadband cellular network operating frequency band is M, and the number of PRBs is N+1 The average throughput of nodes in the first coverage area is higher than when the number of PRBs is N:

(a) If N/(N+R) is not lower than the preset frequency domain resource ratio threshold, and the cellular network throughput is lower than R+M when the number of PRBs is R+M-1, then the wireless broadband cellular network The downlink transmission uses M+R PRBs on the working frequency band of the cellular network, the transmission between nodes in the first coverage area, and the transmission with the nodes in the second coverage area use N PRBs on the working frequency band of the wireless ad hoc network, and the second The transmission between nodes in the coverage area uses N+R PRBs of the working frequency band of the wireless ad hoc network.

(b) If the number of PRBs is R+MR ₁ (R ₁ <R) and R+M, the cellular network throughput is the same, and the network throughput when the number of PRBs is R+MR ₁ -1 is lower than the number of PRBs R+ When MR is ₁ , N+R ₁ PRBs are used for transmission between nodes in the first coverage area and transmission with nodes in the second coverage area. Further, assuming that there is a PRB number R ₂ <R ₁ , if the average throughput of the nodes in the first coverage area is the same when the number of PRBs is R ₂ and R ₂ +1, the transmission between nodes in the first coverage area, and the The transmission between nodes in the two coverage areas uses N+R ₂ PRBs. The downlink transmission in the wireless broadband cellular network uses M+RR ₂ PRBs, and the transmission between nodes in the second coverage area uses N+R PRBs in the working frequency band of the wireless ad hoc network.

(c) If N/(N+R) is lower than the preset frequency-domain resource ratio threshold, and the number of PRBs is R+M-1, the throughput of the cellular network is lower than R+M. Suppose there is a PRB number set T, and the PRB number R ₁ in T satisfies (N+R1)/(N+R) not lower than the preset frequency domain resource ratio threshold, and the cellular throughput when the number of PRBs is R+MR ₁ If the throughput reduction ratio does not exceed the preset throughput ratio threshold, N+min(R ₁ ) PRBs are used for transmission between nodes in the first coverage area and transmission with nodes in the second coverage area. The downlink transmission in the wireless broadband cellular network uses M+R-min(R ₁ ) PRBs, and the transmission between nodes in the second coverage area uses N+R PRBs in the working frequency band of the wireless ad hoc network, where min(R ₁ ) Indicates the minimum value of the number R ₁ of PRBs satisfying the condition in the set T.

Step 906, if the working frequency bands used by the wireless broadband cellular network and the wireless ad hoc network do not overlap each other, the transmission between the nodes in the first coverage area and the second coverage area nodes use the working frequency band of the wireless ad hoc network, and the wireless broadband cellular network The downlink transmission uses the working frequency band of the cellular network.

Step 906 is a process of dividing the first frequency domain resource and the second frequency domain resource when the first preset working frequency band does not overlap with the second preset working frequency band at all.

Different resources are allocated for the downlink data transmission of the network and the data transmission of the second network. According to different situations of the two networks, by coordinating frequency domain resource allocation, co-channel interference is avoided or reduced, network transmission performance is improved, and service experience is improved.
