[0032] In order to make the purpose, technical solutions and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings.

[0033] First, a simple introduction to the noun involved in the present application example:

[0034] Heterogeneous networks are networks composed of two or more different networks, two or more different networks use different wireless technologies, and networks are independent of each other, and information interaction or resource coordination is not performed. In one example, the heterogeneous network includes wireless cellular networks such as LTE, wireless self-network. Wireless Based Network is a temporary autonomous network that includes multiple communication nodes. Between the nodes in the network, each communication node is a wireless transceiver, transmitting, forwarding, and receiving functions, so two nodes in the network can communicate through direct link or multi-hop links. Compared to traditional cellular networks, wireless self-networking does not need to rely on infrastructure. It has the advantages of simple network flexible, high network reliability, and large coverage, widely used in public safety, military battlefields, post-disaster reconstruction and emergency tasks. Wireless 禄 The network includes two modes of TDD and FDD. In TDD-LTE, the upper and downstream transmission between the cellular base station and the terminal uses the same operating frequency band, and the upper downlink transmission occurs within different subframes. In the FDD-LTE, the upper and downstream transmission between the cellular base station and the terminal uses different working frequency bands, and only uplink transmission and downlink transmission are performed on each operating frequency band. Please refer to figure 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 self-network nodes 120, and terminal 130, wherein the terminal 130 can be implemented as a wireless self-network node. The wireless self-assembled network network is added, or the terminal can receive the signal transmitted by the wireless broadband cellular network base station 110, which implements communication functions performed by the wireless broadband cellular network base station 110, that is, at this time, the terminal 130 is located in the heterogeneous network 100.

[0035] In a wireless broadband LTE cellular network or wireless self-networking using LTE technology, the operating frequency band contains two parts: the protection frequency band and the transmission frequency band, and the transmission band is divided into multiple subcarriers, please refer to figure 2 When the 10 MHz operating frequency band 200 is divided into 600 sub-carrier 201, each sub-carrier 201 has a bandwidth of 15 kHz. In a 0.5 ms time slot, a time-frequency resource consisting of 7 orthogonal frequency division multiplexing, OFDM symbols 202 and 12 sub-carrier 201 is called a physical resource block (Physical Resource Block, PRB ), I.e., unit time frequency resource 203. The unit time-frequency resource 203 is the smallest unit of frequency domain resource allocation, and one or more unit time-frequency resources are required for each data transmission.

[0036] Such as figure 1 In the heterogeneous network shown, since the network is independent, when the communication interaction between the terminal and the heterogeneous network, the interference is easily generated, resulting in a decrease in transmission efficiency of the data. Therefore, it is necessary to determine the frequency domain resources used for different types of network communication.

[0037] image 3 A flowchart of a division method of one frequency domain resource provided herein is shown in accordance with the method, and the method is applied to the computer device. The method includes:

[0038] Step 301 determines the first preset working frequency band corresponding to the first network, the first network includes a wireless broadband cellular network.

[0039]The execution body of the present application is a computer having a computational function. Alternatively, the computer first acquires the network state of the first network before performing determination of the first preset operating frequency band. Wherein, the network state of the first network includes a first preset working frequency band corresponding to the first network, i.e., the frequency range occupied by the first network when communicating. The network state of the first network also includes a network identity of the first network, and the first network is in the preset signal strength and at least one of the transmission capability of the first network in the preset.

[0040] In the present application embodiment, the first network corresponds to a wireless broadband cellular network. In the wireless broadband cellular network, the transmitted power of uplink transmission is smaller, and does not cause terminal transmitted in the wireless self-assembled network. Therefore, in the present application embodiment, the first preset working frequency band corresponding to the first network, that is, Wireless broadband cellular network downlink transmission preset working frequency band.

[0041] In the present application, the first network can also be the same different kinds of wireless networks as the wireless broadband cellular network, i.e., corresponding to a network having signal transmission base stations, the present application is not limited to the specific form of the first network.

[0042] Step 302 determines the second preset operating frequency band corresponding to the second network, the second network is a network of different types of the first network, and the second network includes a wireless self-network network.

[0043] As described above, the computer is acquired before the determination of the second preset operating frequency band is performed. The network state of the second network includes a second preset working frequency band corresponding to the second network, i.e., the frequency range occupied by the terminal when communication is performed. The network state of the second network also includes a network identity of the second network, and the second network is at least one of the signal strength and the second network in the preset.

[0044] In the present application embodiment, the second network is a wireless self-assembly network. Wireless Based Network is a temporary autonomous network that includes multiple communication nodes. Between the nodes in the network, each communication node is a wireless transceiver, transmitting, forwarding, and receiving functions, so two nodes in the network can communicate through direct link or multi-hop links. Compared to traditional cellular networks, wireless self-networking does not need to rely on infrastructure. It has the advantages of simple network flexible, high network reliability, and large coverage, widely used in public safety, military battlefields, post-disaster reconstruction and emergency tasks.

[0045] In the present application, the first network can also be the same different kinds of wireless networks as the wireless broadband cellular network, i.e., correspond to a network having at least two wireless nodes, the present application is not limited to the specific form of the second network.

[0046] Step 303, based on the frequency domain difference between the first preset working frequency band and the second preset working frequency band, divided the first frequency domain resource and the second frequency domain resource, wherein the first frequency domain resource is downside through the first network. The frequency domain resource occupied when transferring, the second frequency domain resource is the frequency domain resource occupied by the second network.

[0047] As described 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 after the comparison of the first preset operating frequency band and the second preset working frequency band. Differences with the frequency band of the second preset working frequency band. Alternatively, in this application, only the difference in frequency domain resources is considered to obtain the frequency band difference between the first preset operating frequency band and the second preset working frequency band, that is, the weight of the unit time-frequency resource in the frequency band. In one example, please refer to Figure 4 The first preset operating frequency band 401 includes 50 unit time-frequency resources, and the second preset operating frequency band 402 includes 50 unit time-frequency resources, and frequency in the first preset operating frequency band 401 Attach the frequency corresponding to the frequency resource of the unit time in the second preset working frequency band 402, at this time, the first preset working frequency band 401 is completely coincident with the second preset working frequency band 402; in another example, please refer to Figure 5 The first preset operating frequency band 501 includes a + B unit time-frequency resource, and the second preset operating frequency band 502 includes B + C unit time-frequency resources, and B + C = 50. And the B unit time in the first preset working frequency band 50 is combined with each unit of the B unit in the second preset operating frequency band 502. That is, the first preset operating frequency band 501 has a repetitive B unit time-frequency resource in the second preset operating frequency band 502. At this time, the first preset operating frequency band 501 is partially coincident with the second preset working frequency band 502; In another example, please refer to Figure 6 The first preset working frequency band 601 includes 50 unit time-frequency resources, and the second preset operating frequency band 602 includes 50 unit time-frequency resources, and any of the first preset operating frequency band 601 frequency frequency None of any of the second preset working band 602 corresponds to equal, i.e., the first preset operating frequency band 601 is completely not coincident with the second preset operating frequency band 602.

[0048] As described above, the case where the first preset working frequency band is completely coincident with the second preset operating frequency band, and the first preset working frequency band is coincident with the second preset working band portion as a first coupling. When the second coupling, the case where the first preset working frequency band is completely not coincident with the second preset working band as a third coupling. In one example, the process is based on the coupling of the first preset working flat band and the second preset working frequency band, determines the frequency domain difference between the first preset working frequency band and the second preset working frequency band, and further divides The first frequency domain resource and the second frequency domain resource process.

[0049] After determining the frequency domain difference between the first preset working frequency band and the second preset working frequency band, the computer device can perform the first time-frequency resources and the allocation of the second time-frequency resource according to the frequency band, where the first time is Frequency resource is the frequency domain resource for the first network for the first network, the second time-frequency resource is the frequency domain resource for data transmission of the second network.

[0050] In the present application embodiment, when the wireless broadband cellular network base station has the ability to interact with the node in the wireless self-assembled network, the computer device having the computable power can be implemented as a wireless broadband cellular network base station, the base station directly performs the frequency domain. The calculation and configuration of the distribution method of resources; when the wireless broadband cellular network base station is unable to communicate with the node in the wireless self-assembled network, that is, the computer device with calculating power is implemented as a third-party computer device. After the third-party computer device performs the calculation and configuration of the frequency domain resource, the configuration results are sent to the wireless broadband cellular network base station and the wireless self-assembled node to perform the corresponding division of the frequency domain resource.

[0051] In summary, the method provided in this embodiment is determined corresponding to the first network and the second network to determine the respective preset working frequency bands respectively, and is the first network based on the difference between the two in the working frequency domain. Down-line data transfer and data transfer of the second network allocate different resources. According to different situations of the two networks, network transmission performance is improved, and the network transmission performance is improved, and the business experience is improved.

[0052] As described above, in some embodiments of the present application, the difference in the first preset working frequency band and the second preset working frequency band includes three: first preset working frequency band completely coincides with the second preset working frequency band. The first preset working frequency band is completely undollarged with the second preset working frequency band and the first preset working frequency band is incompletely coincident with the second preset working band. Correspondingly, the first frequency domain resource corresponding to the first network will change the second frequency domain resource corresponding to the second network. At the same time, between the allocation of the frequency domain resource, the area covered by the first network is divided according to the interference generated between the first network and the second network, providing different from the location of different network nodes. Frequency domain resources. Figure 7 A flowchart of a division method of one frequency domain resource provided herein is shown in accordance with the method, and the method is applied to the computer device. The method includes:

[0053] Step 701 determine the reception performance of the second network node.

[0054] In the present application embodiment, the first network is a wireless broadband cellular network, and the second network is a wireless home network. Correspondingly, the second network includes at least two network nodes. In the present application embodiment, the node is the second network node. Since the first network is in a superposed state, the second network node is located in the coverage area of ​​the first network. In the present application embodiment, the node in the second network corresponds to reception performance. The node in the second network is affected by the first network for the reception capacity of the signal. Therefore, in the present application embodiment, the reception performance of the second network node is the signal dry noise ratio of the second network node.

[0055] Step 702 When the signal dry noise ratio corresponding to the second network node is not greater than the signal dry noise ratio threshold, it is determined that the second network node belongs to the first coverage area.

[0056] The signal of the sanodes noise ratio is the ratio of the noise of the signal and interference in the system. In the present application embodiment, the signal dry noise ratio is a second network node, that is, the node in the wireless self-assembly network receives the signal sent to the other node, and the interference from the wireless broadband cellular network base station received by the node. The proportion of signals. In the present application embodiment, the determination of the signal drying ratio is performed by setting the ideal node in the radiation region of the wireless broadband cellular network base station, and belonging to the wireless self-assembled network. In one example, the ideal node of the preset signal intensity is set at the preset distance of the node in the wireless self-assembled network, and the signal dry noise ratio of the node in the wireless self-assembly network is detected to determine the second network node. The corresponding signal dry noise ratio is greater than the signal dry noise ratio threshold. When the signal dry noise ratio corresponding to the second network node is not greater than the signal dry noise ratio threshold, that is, the second network node receives a large influence of the wireless broadband cellular network. At this time, the second network node belongs to the first coverage area. .

[0057] It should be noted that there is a variety of "thresholds" in this application, including the signal dry noise ratio threshold. In the embodiment according to the present application, the threshold can be pre-stored in the computer device, and the value called during the execution process, or the value of the temporary setting in the execution of the program. The specific setting method of the threshold is not limited.

[0058] Step 703 determines the first coverage area based on the second network node belonging to the first coverage area.

[0059] In the present application embodiment, the nodes of all the sanodes no more than the signal dry noise ratio threshold are divided into the first coverage area by the method in step 702.

[0060] Step 704, the second coverage area that is not coincident with the first coverage area is determined in the coverage area of ​​the first network.

[0061] In the present application embodiment, within the coverage area of ​​the first network, the first coverage area is not coincident with the second coverage region. In one example, within the coverage area of ​​the first network, after determining the first coverage area, the remainder is divided into the remainder of the remainder in accordance with the preset rules stored in the computer device, and 50% of the remaining portion is divided into a second coverage area; In another example, within the coverage area of ​​the first network, the position in the first coverage area is a second coverage area. In the present application embodiment, in the coverage area of ​​the first network, the position in the first cover area is a second coverage area as an example. Since the number of wireless broadband honeycomb network base stations is 1 in the present application, and the signal strength of the wireless broadband cellular network base station is weakened with the signal. Figure 8 As shown, corresponding to the wireless broadband cellular network base station 800, there is a first coverage area 801 and the second cover area 802, wherein the first cover area 801 is a circle of the center of the wireless broadband honeycomb network base station 800, the second coverage area 802 is The ring located outside it. In the first cover area 801 and the second coverage area 802, each wireless self-network node 810 is included.

[0062] Step 705 determine the first preset working frequency band corresponding to the first network.

[0063] Step 706 determines the second preset working frequency band corresponding to the second network.

[0064] Steps 705 to 706 are corresponding to steps 301 to 302, and will not be described herein.

[0065] Step 707 When the first preset operating frequency band is completely coincident with the second preset operating frequency band, the throughput change threshold is determined.

[0066] In one example of the present application embodiment, the first preset operating frequency band and the second preset working frequency band are completely coincident.

[0067] In the present application embodiment, the first network, that is, the wireless broadband cellular network corresponds to a first network throughput, and the node of the wireless self-networking corresponds to node throughput. The corresponding node throughput, the average throughput of the first coverage area, and the average throughput of the second coating area in the second coverage area, and the node within the wireless self-network range also corresponds to the total average Throughput, that is, second network throughput

[0068] In the computer device, there should be a first network throughput threshold corresponding to the first network throughput. In one example, the first network throughput threshold can indicate the throughput change ratio, in another example, the first network throughput threshold can be the current throughput change value. This application does not limit the first network throughput threshold.

[0069] Step 708, configure M to the first frequency domain resource 1 Time-frequency resources.

[0070] Step 709 When the first frequency domain resource is configured 1 +1 unit time-frequency resources, the first network throughput change is greater than the throughput change threshold, determine the number of unit time-frequency resources in the first frequency domain resource Number N 1 -M 1.

[0071] In the present application embodiment, N1 is the number of unit time-frequency resources of the first preset operating frequency band and the second preset operating frequency band. Since the first preset working frequency band is completely coinctered with the second preset working frequency band, N 1 That is, the number of unit time-frequency resources in the first preset operating frequency band, or the number of unit time-frequency resources in the second preset operating frequency band.

[0072] In the present application embodiment, when the number of unit time-frequency resources configured to the first frequency domain resource is too large, the first network throughput corresponding to the wireless broadband cellular network will decrease, and the amount of change in its decrease is greater than the throughput change. When the threshold is determined to determine the number of time-frequency resources in the first frequency domain resource is n 1 -M 1.

[0073] Step 710 to configure K to the second frequency domain resource 1 Time-frequency resources.

[0074] In determining the number of times time frequency resources in the first frequency domain resource, N 1 -M 1 After the second frequency domain resource is performed, the configuration of the second frequency domain resource is performed. In one example, you can directly configure M 1 A unit time-frequency resource as the number of unit time-frequency resources within the second frequency domain resource. However, in order to ensure signal transmission efficiency within the second frequency domain resource, for M 1 A frequency domain resource is selected.

[0075] Step 711 When the second frequency domain resource is configured to 1 +1 unit time-frequency resources, the first coverage area throughput is unchanged, determine the unit time-frequency resources in the second frequency domain resource in K 1.

[0076] In the present application embodiment, when the configuration of the unit time-frequency resource is performed, the throughput corresponding to the first cover area is unchanged, that is, the communication in the first cover area is not affected by the configuration of the time-frequency resource. At this time, That is to determine the unit time frequency resources in the second frequency domain resource are k 1.

[0077] In another embodiment of the present application, the first preset working frequency band is partially coincident with the second preset working band portion.

[0078] In the examples of this application, k 1 1 1 , And k 1 N 1 , M 1 All are positive integers

[0079] Step 712, when the first preset working frequency band is coinctered with the second preset working band portion, determine N 2 The number of non-weight ratios of the number of time-frequency resources with the second preset working frequency band.

[0080] This non-weight ratio is the ratio of the number of time-frequency resources of the number of unit time-frequency resources of the coincident portion and the second preset operating frequency band corresponding to the wireless self-network network. In one example, the total number of times of the second preset working frequency band is 100, and the number of times the combined portion is 10, and the non-coincidence ratio is 10/100 = 0.1.

[0081] Step 713, when the non-weight ratio is not lower than the frequency domain resource ratio threshold, M2 is configured to configure M2 units to the first frequency domain resource.

[0082] In the present application embodiment, the frequency domain resource ratio threshold is stored in the computer device. The frequency domain resource ratio threshold is a threshold corresponding to the non-weight ratio. When the no-weight ratio is higher than or equal to the resource ratio threshold, steps 713 to 717 are performed, and when the no-weight ratio is lower than the resource ratio threshold, step 718 is performed. Step 719.

[0083] In the examples of the present application, m 2 In order to correspond to the first preset working frequency band part, the number of times the unit time-frequency resource configured to the first frequency domain resource is configured when the second preset operating frequency band is partially coincident.

[0084] Step 714 When the first frequency domain resource is configured 2 -1 unit time-frequency resources, when the first network throughput changes, determine the number of unit time-frequency resources in the first frequency domain resource in m. 2.

[0085] In the present application embodiment, in the same manner as described in step 709, the first network throughput is determined for the number of unit time-frequency resources in the first frequency domain resource, in the present application embodiment, in the first frequency domain resource The number of unit time-frequency resources is 2.

[0086] Step 715: Determine the number of times the frequency resource in the second frequency domain resource is n 2 + R1, where the number of available units in the first coverage area is N 2 A number of time-frequency resources in the second coverage area is n 2 + R1.

[0087] In the present application embodiment, since some units within the first cover area are affected by the wireless broadband cellular network, the number of times available in the unit is small, and the unit time in the second coverage area is radically There is less influence in broadband network, and the number of units available in the unit is more, so the number of time-frequency resources in the second frequency domain resource configured to wireless self-network network is N. 2 + R1, where the number of available units in the first coverage area is N 2 A number of available units in the second coverage area is n 2 + R1.

[0088] It should be noted that in the embodiment of the present application, M 2 N 2 All of R1 is positive.

[0089] Step 716 When the first frequency domain resource is configured 2 -r 2 Time-frequency resources, the first network throughput does not change, and configure M to the first frequency domain resource 2 -r 2 -1 time-frequency resources, the first network throughput changes, determine the number of unit time-frequency resources in the first frequency domain resource in the first frequency domain. 2 -r 2.

[0090] Step 717: Determining the number of time-frequency resources in the second frequency domain resource is n 2 + R1, where the number of time-frequency resources in the first coverage area is N 2 Number of time-frequency resources in the second coverage area of ​​the second coverage area is n 2 + R1, R 2 For positive integers.

[0091] Steps 716 to 717 are changed to the number of frequency resources of the corresponding configured unit, but the first frequency domain resource and the number of time-frequency resources allocated in the second frequency domain resource are not changed.

[0092] Step 718, when the no-weight ratio is lower than the frequency domain resource ratio threshold, the number of time-frequency resources is determined.

[0093] Step 719: Determine the number of unit time-frequency resources in the first frequency domain resource based on the number of units, and the number of time-frequency resources in the second frequency domain resource.

[0094] As described in steps 718 to 719, when the no-weight ratio is lower than the frequency domain resource ratio threshold, that is, the inconsistency ratio indicating the first preset operating frequency band and the second preset working frequency band is smaller, and can be distributed. Frequency resources are also limited. At this time, the number of time-frequency resources corresponding to the first frequency domain resource and the second frequency domain resource will be determined, thereby determining the number of time-frequency resources in the first frequency domain resource and the second frequency domain resource.

[0095] Step 720, when the first preset working frequency band is not coincident with the second preset working frequency band, the first preset operating frequency band is determined as the first frequency domain resource, and the second preset operating frequency band is determined as the second frequency domain. Resources.

[0096] In the present application embodiment, when the first preset working frequency band is completely not coincident in the communication process, communication between the first network and the second network is difficult to generate interference, so the first The frequency domain resource will directly correspond directly to the first preset working frequency band, and the second frequency domain resource corresponds directly to the second preset working frequency band.

[0097] In summary, the method provided in this embodiment is determined corresponding to the first network and the second network to determine the respective preset working frequency bands respectively, and is the first network based on the difference between the two in the working frequency domain. Down-line data transfer and data transfer of the second network allocate different resources. According to different situations of the two networks, network transmission performance is improved, and the network transmission performance is improved, and the business experience is improved by coordinating the frequency domain resource allocation, avoiding or lowering the common channel interference.

[0098] The method provided in this embodiment, corresponding to the node reception performance of the second network, divides the coverage area of ​​the first network, and correspondingly different operating frequency domain differences and different coverage areas after division, set different frequency domain resources. In the case where the different node state is correspondingly improved, the transmission performance of the data is further improved.

[0099] Figure 9 A process diagram showing a division method of a frequency domain resource provided in accordance with an exemplary embodiment of the present application, please refer to Figure 9 This process includes:

[0100]Step 901, according to the reception performance of the wireless self-network node of different positions, 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 self-network node is divided into the first coverage area node and the first Second cover area node.

[0101] The process is a process for covering the area division for the cover area of ​​the first network. After performing the division of the first cover area and the second cover area, the network node corresponding to the second network is also summarized to the corresponding coverage. area.

[0102] In one example, the method of receiving the first coverage area and the second coverage area according to the receiving performance of the wireless self-network node of different locations is as follows:

[0103] Assuming two wireless self-network nodes A and Node B, node A are sending nodes, and Node B is a receiving node. The transmission distance between the two nodes is a preset transmission distance, and the transmit power of node A is maximum transmit power. On the same channel, when the node B receives the transmit signal and the interference signal of the node A and the interference signal of the cellular network base station, the reception signal dry noise ratio of Node B is not higher than the preset belt dry noise ratio, which satisfies the node B of the above conditions. The location set is the first coverage area, and the other area in the coverage area of ​​the cellular network base station is the second coverage area.

[0104] Step 902, if the wireless broadband cellular network downlink transmission and wireless self-network use the same operating frequency band, the frequency domain resource of the working frequency band is divided into the first frequency domain resource set and the second frequency domain resource collection according to the PRB ratio.

[0105] The "first frequency domain resource set" in the present process, that is, the "second frequency domain resource" in the foregoing embodiment, the "second frequency domain resource set" in the present process, that is, in the foregoing embodiment "First Frequency Domain Resources". Steps 902 to step 903 are the division of the first frequency domain resource and the second frequency domain resource when the corresponding first preset operating frequency band is completely coincident with the second preset operating frequency band.

[0106] Step 903: Downstream Transmission within the wireless broadband cellular network uses the second frequency domain resource set, the transmission between the first overlay area node, and the transmission of the first frequency domain resource with the transmission between the second coverage area node, the second Covering the transmission between the region nodes using all frequency domain resources of the operating frequency band.

[0107] In this case, as described in the following example:

[0108] 1 If the number of PRBs in the second frequency domain resource collection is less than the number of PRBs of the entire operating frequency band, the honeycomb network throughput is not lowered, but the cellular network throughput is at least n + 1 PRB. Starting, the first frequency domain resource set contains N PRB. Further, it is assumed that there is a PRB number m

[0109] 2 If the number of PRBs in the second frequency domain resource set is less than the number of PRBs of the entire operating frequency band, the honeycomb network throughput begins to decrease, and a throughput ratio threshold is preset. When the number of PRBs in the second frequency domain resource set is less than the number of PRBs of the entire operating frequency band, the throughput reduction ratio does not exceed the preset throughput ratio threshold, but the throughput reduction ratio is reduced when there is less n + 1 PRB. Start exceeding the preset throughput ratio threshold, the first frequency domain resource set contains N PRB. Further, it is assumed that there is a PRB number m

[0110] Step 904, if the wireless broadband cellular network and the operating frequency band used by the wireless self-networking are partially coincident, the network throughput of the wireless cellular network and the average throughput of the first coverage area node determine the assignment of the overwhelming part of the network throughput of the wireless cellular network. .

[0111] Steps 904 to step 905 are the division of the first frequency domain resource and the second frequency domain resource when the corresponding first preset operating frequency band is coincident with the second preset working band portion.

[0112] Step 905, the downlink transmission within the wireless broadband cellular network uses the non-redefined partial frequency domain resource on its operating frequency band and the frequency domain resources of all / part coincides, the transmission between the first coverage area node, and the second coverage area The transmission between nodes uses a non-redeveloped partial frequency domain resource on the wireless self-network operating frequency and all frequency domain resources of all / part coincides, and the transmission between the second overlay area node uses all wireless self-network operating frequency bands. Frequency domain resources.

[0113] In this case, as described in the following example:

[0114] 1 Suppose the number of PRBs from the non-coincident portion on the wireless self-network operating frequency band is n, if the number of PRBs is N and N + 1, the average throughput of the first coverage area node is the same, the downlink transmission within the wireless broadband cellular network uses cellular The frequency domain resource on the network working frequency, the transmission between the first overlay area node, and the transmission between the second cover area node uses the frequency domain resource of the non-coincident portion of the wireless self-network operating frequency band, the second coverage area node The transmission uses all frequency domain resources for wireless self-network working frequency bands.

[0115] 2 Suppose the number of PRBs of the non-coincident portion on the wireless self-assembled web operating frequency band is n, the number of PRBs of the coincident portion is R, the number of PRBs of the non-coincident portion on the wireless broadband cellular network operating frequency band is m, and the number of PRB is N + 1 The average throughput of the first cover area node is higher than the number of PRBs:

[0116] (a) If N / (N + R) is not lower than the preset frequency domain resource ratio threshold, and the honeycomb network throughput is lower than R + M when the number of PRBs is R + M-1, the wireless broadband cellular network Downlink Transport uses M + R PRB on the cellular network, transfer between the first overlay area node, and the transmission between the wireless self-network operating frequency band with the transmission between the second coverage area node, the second Transfer between the coverage area node uses the N + R PRB of the Wireless Self-Network operating frequency band.
