Description
Technical Field
[0001] Embodiments of the present invention relate to the field of communications, and in particular, to a method, device, storage medium and electronic device for detecting interference of a transmission beam. Background Art
[0002] In a distributed system, it is generally necessary to equip access nodes with multiple antennas according to different geographical locations, connect to the central processing unit through a high-speed backhaul link, or realize information interaction between multiple adjacent access nodes through a high-speed link. Such a distributed system realizes spatial multiplexing by enabling multiple access nodes on the network side to use the same time-frequency resources to complete communication transmission with their respective service terminals. However, the distributed deployment of access nodes makes the interference relationship between transmission beams on the network side related to the specific location of the terminal, and there is no longer a rule that transmission beams with similar directions in traditional cellular base stations have stronger interference. At the same time, the beam implementation methods on the terminal side of different manufacturers are not the same and are unknown to the network side, which may cause different terminals to experience different interference levels for the same transmission beam on the network side.
[0003] Therefore, the transmission beam interference relationship of the distributed system cannot utilize the rules of traditional cellular base stations, which means that the interference relationship between any two transmission beams on the network side needs to be measured based on the terminal served each time. As network access nodes are deployed more and more densely, the number of access nodes and transmission beams in the same cell has greatly increased. The existing technology for measuring and managing interference for transmission beams has caused the system's measurement resource overhead and measurement delay to increase dramatically.
[0004] With regard to the problems in related technologies such as low detection efficiency of transmission beams, no effective solutions have been proposed yet. Summary of the invention
[0005] Embodiments of the present invention provide a transmission beam interference detection method, device, storage medium and electronic device to at least solve the problem of low transmission beam detection efficiency in related technologies.
[0006] According to an embodiment of the present invention, a transmission beam interference detection method is provided, comprising:

[0009] A target interference relationship between the first transmission beam and the transmission network is detected according to the one or more reference interference relationships, wherein the target interference relationship is used to perform transmission beam selection and time-frequency resource scheduling for terminals in the transmission network, and the terminals in the transmission network include the target terminals.
[0010] According to another embodiment of the present invention, there is provided a transmission beam interference detection device, comprising:

[0012] a first acquisition module, configured to respond to the transmission request, obtain, from a beam interference relationship set corresponding to the transmission network, an interference relationship between the first transmission beam and each second transmission beam in the transmission beam set, to obtain one or more reference interference relationships, wherein the beam interference relationship set is used to record the interference relationship between any two of the multiple transmission beams before receiving the transmission request, and the transmission beam set includes all transmission beams currently used in the transmission network;
[0013] A detection module is used to detect a target interference relationship between the first transmission beam and the transmission network based on the one or more reference interference relationships, wherein the target interference relationship is used to perform transmission beam selection and time-frequency resource scheduling for terminals in the transmission network, and the terminals in the transmission network include the target terminals.

[0015] According to yet another embodiment of the present invention, there is provided an electronic device, including a memory and a processor, wherein the memory stores a computer program, and the processor is configured to run the computer program to execute the steps in any one of the above method embodiments.
[0016] Through the present invention, when a transmission request is received from a target terminal requesting to use a first transmission beam to transmit data in a transmission network, the interference relationship between the first transmission beam and each second transmission beam in the transmission beam set is obtained from the beam interference relationship set, and then the target interference relationship between the first transmission beam and the transmission network can be detected according to the interference relationship between the first transmission beam and each second transmission beam in the transmission beam set. Since the interference relationship between the two transmission beams before receiving the terminal transmission request is pre-recorded in the beam interference relationship set, when a transmission request is received, it is only necessary to perform an acquisition operation from the pre-constructed beam interference relationship set to determine the situation of the target terminal corresponding to the first transmission beam performing transmission beam selection and time-frequency resource scheduling according to the interference relationship recorded in the beam interference relationship set. In other words, the interference relationship between any two transmission beams can be determined in real time through the pre-constructed beam interference relationship set, without having to perform multiple repeated measurements based on the terminal served each time, thereby reducing the measurement resource overhead and measurement delay of the system. Therefore, the problem of low detection efficiency of the transmission beam can be solved, and the efficiency of detection of the transmission beam can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.
[0032] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.
[0033] In this embodiment, a transmission beam interference detection method running on the above mobile terminal is provided. Figure 2 is a flow chart of interference detection of a transmission beam according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:
[0034] Step S202, receiving a transmission request in a transmission network, wherein the transmission request is used to indicate that the target terminal requests to use a first transmission beam in the transmission network to transmit data, and the transmission network is used to provide a plurality of transmission beams for the terminal to transmit data, and the plurality of transmission beams include the first transmission beam;
[0035] Step S204: In response to the transmission request, obtain, from a beam interference relationship set corresponding to the transmission network, an interference relationship between the first transmission beam and each second transmission beam in the transmission beam set, to obtain one or more reference interference relationships, wherein the beam interference relationship set is used to record the interference relationship between any two of the multiple transmission beams before receiving the transmission request, and the transmission beam set includes all transmission beams currently used in the transmission network;
[0036] Step S206, detecting a target interference relationship between the first transmission beam and the transmission network based on the one or more reference interference relationships, wherein the target interference relationship is used to perform transmission beam selection and time-frequency resource scheduling for terminals in the transmission network, and the terminals in the transmission network include the target terminals.
[0037] Through the above steps, when a transmission request is received from a target terminal requesting to use a first transmission beam to transmit data in a transmission network, the interference relationship between the first transmission beam and each second transmission beam in the transmission beam set is obtained from the beam interference relationship set, and then the target interference relationship between the first transmission beam and the transmission network can be detected according to the interference relationship between the first transmission beam and each second transmission beam in the transmission beam set. Since the interference relationship between the two transmission beams before receiving the terminal transmission request is pre-recorded in the beam interference relationship set, when a transmission request is received, it is only necessary to perform an acquisition operation from the pre-constructed beam interference relationship set to determine the situation of the target terminal corresponding to the first transmission beam performing transmission beam selection and time-frequency resource scheduling according to the interference relationship recorded in the beam interference relationship set. In other words, the interference relationship between any two transmission beams can be determined in real time through the pre-constructed beam interference relationship set, without having to perform multiple repeated measurements based on the terminal served each time, thereby reducing the measurement resource overhead and measurement delay of the system. Therefore, the problem of low detection efficiency of the transmission beam can be solved, and the efficiency of detection of the transmission beam can be improved.
[0038] Optionally, in this embodiment, the execution subject of the above-mentioned transmission beam interference detection method may be, but not limited to, a network-side central processing unit, a baseband processing unit, a centralized unit, etc. The above-mentioned transmission beam interference detection method may be, but not limited to, applied in millimeter wave communication systems, 5G NR (5th Generation New Radio) systems, and the like.

[0144] Optionally, in this embodiment, the above-mentioned multiplexing probability threshold may be, but is not limited to, predetermined, and is used to indicate whether the spatial multiplexing condition is satisfied between the first transmission beam and the second transmission beam corresponding to the reference interference relationship, for example: when the first multiplexing probability is greater than or equal to the multiplexing probability threshold and the second multiplexing probability is greater than or equal to the multiplexing probability threshold, it may be, but is not limited to, determined that the spatial multiplexing condition is satisfied between the first transmission beam and the second transmission beam corresponding to the reference interference relationship. Alternatively, when the first multiplexing probability is less than the multiplexing probability threshold or the second multiplexing probability is less than the multiplexing probability threshold, it is determined that the spatial multiplexing condition is not satisfied between the first transmission beam and the second transmission beam corresponding to the reference interference relationship.
[0145] Optionally, in this embodiment, when the first multiplexing probability is greater than or equal to the multiplexing probability threshold and the second multiplexing probability is greater than or equal to the multiplexing probability threshold, it is determined that the spatial multiplexing condition is met between the first transmission beam and the second transmission beam corresponding to the reference interference relationship, and it is considered that the target interference relationship between the first transmission beam and the second transmission beam does not require interference avoidance, and spatial multiplexing is allowed.

[0147] Optionally, in this embodiment, the interference probability threshold may be, but is not limited to, predetermined and used to indicate an interference relationship between the first transmission beam and the second transmission beam corresponding to the reference interference relationship. The target interference relationship may include, but is not limited to, whether the first transmission beam and the second transmission beam corresponding to the reference interference relationship satisfy an interference avoidance condition.
[0148] In an optional implementation, a method for detecting a target interference relationship is provided. Figure 6 A method for detecting a target interference relationship according to an embodiment of the present application is shown in FIG. Figure 1 ,like Figure 6 As shown, taking the cell as a transmission network, the transmission beam 1 of the current access node 1 of the cell and the terminal 1 as an example of communication service, the resources required for the transmission beam 4 to be scheduled associated with the terminal 2 can be scheduled in the following manners, but not limited to:
[0149] Step 1: When transmission beam 1 of access node 1 communicates with terminal 1, the network side receives the transmission demand of newly added terminal 2, and terminal 2 is associated with access node 2 and transmission beam 4. The network side needs to make a scheduling decision on the resources required for transmission beam 4 to be scheduled associated with terminal 2, and select the access node and corresponding transmission beam to serve terminal 2. The network side makes a conditional judgment on the transmission beam to be scheduled associated with the terminal and the transmission beam being served by the current cell.
[0150] Step 2: Set the reuse probability threshold to K reu =0.9, perform spatial multiplexing condition judgment on the transmission beam 4 to be scheduled associated with the terminal and the transmission beam 1 being served by the current cell, and obtain the first multiplexing probability β of the transmission beam 4 (first transmission beam) and the transmission beam 1 (second transmission beam) from the pre-constructed beam interference relationship set (Table 1) 1,4 (Multiplexing probability of the first transmission beam on the second transmission beam) and the second multiplexing probability β 4,1 (The multiplexing probability of the second transmission beam to the first transmission beam) is β4,1 =0.9,β 1,4 =0.9, compare the first multiplexing probability and the second multiplexing probability with the multiplexing probability threshold, and get β m,n ≥K reu ,β n,m ≥K reu .
[0151] Step three: Since the first multiplexing probability and the second multiplexing probability are equal to the multiplexing probability threshold, the mutual interference between the transmission beam 4 to be scheduled associated with the terminal and the transmission beam 1 being served by the current cell is very small and can be ignored. The scheduled time-frequency resources can overlap, and there is no need to avoid interference, and spatial multiplexing can be performed.
[0152] Step 4: The network side selects the transmission beam of the terminal and schedules time-frequency resources based on the interference relationship between the transmission beam to be scheduled associated with the terminal and all the transmission beams being served by the current cell, completes the judgment of interference avoidance and spatial multiplexing, and then performs transmission beam selection and time-frequency resource scheduling for the terminal.
[0153] In an exemplary embodiment, the target interference relationship between the first transmission beam and the second transmission beam can be determined according to the first interference probability and the second interference probability included in each of the reference interference relationships, and an interference probability threshold in the following manner, but is not limited to: determining whether the interference avoidance condition is satisfied between the first transmission beam and the second transmission beam corresponding to the reference interference relationship according to the first interference probability and the second interference probability included in each of the reference interference relationships, and an interference probability threshold; in the case where the interference avoidance condition is satisfied between the first transmission beam and the second transmission beam corresponding to the reference interference relationship, determining that the target interference relationship between the first transmission beam and the second transmission beam requires interference avoidance; in the case where the interference avoidance condition is not satisfied between the first transmission beam and the second transmission beam corresponding to the reference interference relationship, performing an interference test on the target terminal to obtain the target interference relationship between the first transmission beam and the second transmission beam.
[0154] Optionally, in this embodiment, the above-mentioned target interference relationship may include, but is not limited to, whether the interference avoidance condition is satisfied between the first transmission beam and the second transmission beam corresponding to the reference interference relationship. For example, when the first interference probability is greater than or equal to the interference probability threshold and the second interference probability is greater than or equal to the interference probability threshold, it may be, but is not limited to, determining that the interference avoidance condition is not satisfied between the first transmission beam and the second transmission beam corresponding to the reference interference relationship. Alternatively, when the first interference probability is less than the interference probability threshold or the second interference probability is less than the interference probability threshold, it is determined that the interference avoidance condition is satisfied between the first transmission beam and the second transmission beam corresponding to the reference interference relationship.
[0155] In an optional implementation, a method for detecting a target interference relationship is provided. Figure 7 A method for detecting a target interference relationship according to an embodiment of the present application is shown in FIG. Figure 2 ,like Figure 7 As shown, taking a cell as a transmission network, the cell currently has a transmission beam 2 of access node 1 communicating with terminal 1, and at the same time, the network side receives a transmission request from a newly added terminal 2, and the newly added terminal 2 is associated with access node 2 and transmission beam 3 as an example, the target interference relationship between transmission beam 3 and other transmission beams can be determined in the following manner, but not limited to, when the transmission request is received, wherein the transmission request received by the network side is used to indicate that the target terminal (terminal 2) requests to use the first transmission beam (transmission beam 3) to transmit data in the transmission network:
[0156] Step 1: The transmission network includes transmission beam 2 of access node 1 and terminal 1 for communication services. At the same time, the network side receives the transmission demand of the newly added terminal 2, and terminal 2 is associated with access node 2 and transmission beam 3. The network side needs to make a scheduling decision on the resources required for the transmission beam 3 to be scheduled associated with the terminal, select the access node and the corresponding transmission beam to serve the terminal, and make a conditional judgment on the transmission beam to be scheduled associated with terminal 2 and the transmission beam 2 being served by the current cell.
[0157] Step 2: Set the reuse probability threshold K reu K reu =0.9, perform spatial multiplexing condition judgment on the transmission beam 3 to be scheduled associated with the terminal and the transmission beam 2 being served by the current cell: obtain the reference interference relationship between transmission beam 2 (the second transmission beam) and transmission beam 3 (the first transmission beam) from the pre-constructed beam interference relationship set (Table 1), and the reference interference relationship includes the first multiplexing probability β 2,3 (Multiplexing probability of the first transmission beam on the second transmission beam) and the second multiplexing probability β 3,2 (The multiplexing probability of the second transmission beam to the first transmission beam) is β 2,3 =0.1,β 3,2 =0.1, the first multiplexing probability and the second multiplexing probability are compared with the multiplexing probability threshold K reu By comparison, since the first multiplexing probability and the second multiplexing probability do not satisfy the relationship β m,n ≥K reu ,β n,m ≥K reu Therefore, it is determined that the spatial multiplexing condition is not met between transmission beam 2 and transmission beam 3.
[0158] Step 3: Since there is a possibility of mutual interference between the transmission beam 3 to be scheduled and the current transmission beam 2 of the cell, it is necessary to further determine the interference avoidance conditions. The specific process is as follows:

[0171] In an optional implementation, a process for performing an interference test is provided. Figure 8 is a schematic diagram of an execution process of an interference test according to an embodiment of the present application, such as Figure 8 As shown, access node 1 and access node 2 transmit to their respective corresponding terminals, such as Figure 8 As shown in (b), the transmission beam of access node 1 corresponding to terminal 1 and the transmission beam of access node 2 corresponding to terminal 2 do not interfere with each other, and the terminals (terminal 1 and terminal 2) served by each access node (access node 1 and access node 2) will not be interfered by the transmission beams of adjacent access nodes. Figure 8 As shown in (a), the transmission beam of access node 1 interferes with terminal 2, and at the same time, the transmission beam of access node 2 also interferes with terminal 1. For example, if terminal 1 and terminal 2 are determined as target terminals, the transmission beam emitted by terminal 1 is the first transmission beam, and the transmission beam emitted by terminal 2 is the second transmission beam, interference testing can be performed on terminal 1 and terminal 2 in the following ways, but is not limited to:
[0172] The central processing unit instructs terminal 1 (the terminal of the first transmission beam) to keep the receiving beam unchanged, measure the transmitting beam of access node 2, and feed back a first RSRP value; the central processing unit instructs terminal 2 (the terminal of the second transmission beam) to keep the receiving beam unchanged, measure the transmitting beam of access node 1, and feed back a second RSRP value.
[0173] The central processing unit can, but is not limited to, determine the interference relationship between the transmission beams of access node 1 and access node 2 based on the RSPR values of the service access node transmission beams measured by terminal 1 and terminal 2, and the RSRP values of the adjacent node transmission beams measured.
[0174] In an optional implementation, a method for detecting a target interference relationship is provided. Fig. 9 A method for detecting a target interference relationship according to an embodiment of the present application is shown in FIG. Figure 3 ,like Fig. 9 As shown, taking a cell as a transmission network, the cell currently has a transmission beam 1 of access node 1 communicating with terminal 1, and at the same time, the network side receives a transmission request from a newly added terminal 2, and the newly added terminal 2 is associated with access node 2 and transmission beam 3. For example, the target interference relationship between transmission beam 3 and other transmission beams can be determined in the following manner, but not limited to, when the transmission request is received, wherein the transmission request received by the network side is used to indicate that the target terminal (terminal 2) requests to use the first transmission beam (transmission beam 3) to transmit data in the transmission network:
[0175] Step 1: When the transmission beam 1 of access node 1 communicates with terminal 1, the network side (central processing unit) receives the transmission demand of the newly added terminal 2, and terminal 2 is associated with access node 2 and transmission beam 3. The network side needs to make a scheduling decision on the resources required for the transmission beam 3 to be scheduled associated with the terminal, and select the access node and corresponding transmission beam to serve the terminal. The network side makes a conditional judgment on the transmission beam 1 to be scheduled associated with the terminal and the transmission beam being served by the current cell.
[0176] Step 2: Set the reuse probability threshold to K reu =0.9, perform spatial multiplexing condition judgment on the transmission beam 3 to be scheduled associated with the terminal and the transmission beam 1 being served by the current cell, and obtain the first multiplexing probability β between the transmission beam 3 (first transmission beam) and the transmission beam 1 (second transmission beam) from the pre-constructed beam interference relationship set (Table 1) 1,3 (Multiplexing probability of the first transmission beam on the second transmission beam) and the second multiplexing probability β 3,1 (The multiplexing probability of the second transmission beam to the first transmission beam) is β 1,3 =0.5,β 3,1 =0.5, compare the first multiplexing probability and the second multiplexing probability with the multiplexing probability threshold, and according to the condition β m,n ≥K reu ,β n,m ≥K reu It can be seen that there is a possibility of mutual interference between transmission beam 3 and transmission beam 1, and the spatial multiplexing condition is not met.
[0177] Step 3: Since there is a possibility of mutual interference between the transmission beam to be scheduled and the current transmission beam of the cell, the interference avoidance condition can be determined by, but is not limited to, the following methods:
[0178] Assume the interference probability threshold is K inf =0.7, perform interference avoidance condition judgment on transmission beam 3 (first transmission beam) associated with the terminal to be scheduled and transmission beam 1 (second transmission beam) being served by the current cell, and obtain the first interference probability α between transmission beam 2 and transmission beam 1 from the pre-constructed beam interference relationship set (Table 1) 1,3 (Interference probability of the first transmission beam on the second transmission beam) and the second interference probability α 3,1 (The interference probability of the second transmission beam on the first transmission beam) is α 1,3 =0.5,α 3,1 =0.5, compare the first interference probability and the second interference probability with the interference probability threshold, according to the condition α m,n ≥K inf ,α n,m ≥K inf It can be seen that the interference avoidance condition is not met between transmission beam 2 and transmission beam 3, and further interference testing of terminal 2 is required.
[0179] Step 4: The target threshold is set to T = -6dB. The network instructs terminal 2 to keep the receiving beam unchanged. The network transmits the transmission beam with sequence number 1 (the second transmission beam). The terminal measures and feeds back the RSRP value. (first RSRP value); at the same time, the network side instructs the currently served terminal 1 to keep the receiving beam unchanged, the network side transmits the transmission beam with sequence number 3 (first transmission beam), and the terminal measures and feeds back the RSRP value (Second RSRP value). The network side calculates and obtains a second ratio of the first RSRP value to the second RSRP value. and a third ratio of the second RSRP value to the first RSRP value They are The second ratio And the third ratio Compare with the set target threshold, according to the conditions Make a judgment.
[0180] Step 5: Due to the conditions in step 4 The mutual interference between the transmission beam to be scheduled associated with the terminal and the transmission beam being served by the current cell is very small and can be ignored. The scheduled time-frequency resources can overlap, and there is no need to avoid interference, so spatial multiplexing can be performed.
[0181] Step 6: The network side selects the transmission beam of the terminal and schedules time-frequency resources based on the interference relationship between the transmission beam to be scheduled associated with the terminal and all the transmission beams being served by the current cell, and after completing the judgment of interference avoidance and spatial multiplexing.
[0182] Step 7: After terminal 2 accesses the network, the network side may, but is not limited to, iteratively update the interference relationship between transmission beams based on the relevant interference measurement results for terminal 2.
[0183] In an optional embodiment, a transmission beam interference detection process is provided. Fig.10 is a flow chart of an interference detection process of a transmission beam according to an embodiment of the present application, such as Fig.10 As shown, the interference detection of the transmission beam can be performed by, but is not limited to, the following process:
[0184] An interference relationship set of interference relationships between each transmission beam in the transmission network as a first transmission beam and each second transmission beam in the transmission beam set is pre-constructed.
[0185] When receiving a transmission request from a target terminal to use a first transmission beam to transmit data in a transmission network, an interference relationship between the first transmission beam and each second transmission beam in the transmission beam set is obtained from a beam interference relationship set to obtain one or more reference interference relationships.
[0186] Determine whether interference avoidance needs to be performed between the first transmission beam and the second transmission beam according to the first multiplexing probability and the second multiplexing probability included in the reference interference relationship:
[0187] When the first multiplexing probability is greater than or equal to the multiplexing probability threshold and the second multiplexing probability is also greater than or equal to the multiplexing probability threshold, it is determined that the interference between the first transmission beam and the second transmission beam is very small and can be ignored, the scheduled time-frequency resources can overlap, there is no need to perform interference avoidance, and spatial multiplexing can be performed;
[0188] After determining that the first transmission beam and the second transmission beam can be spatially multiplexed, the second transmission beam is adjusted to be the next transmission beam in the current reference interference relationship, and a target interference relationship between the adjusted second transmission beam and the first transmission beam is determined.
[0189] When the first multiplexing probability is less than the multiplexing probability threshold or the second multiplexing probability is less than the multiplexing probability threshold, determining whether there is interference between the first transmission beam and the second transmission beam according to the first interference probability and the second interference probability included in the reference interference relationship;
[0190] When the first interference probability is greater than or equal to the interference probability threshold and the second interference probability is greater than or equal to the interference probability threshold, it is determined that there is interference between the first transmission beam and the second transmission beam, the scheduling time-frequency resources cannot overlap, and interference avoidance is required;
[0191] When the first interference probability is less than the interference probability threshold or the second interference probability is less than the interference probability threshold, an interference test is performed on the first transmission beam and the second transmission beam, and a target interference relationship is determined according to a result of the interference test.
[0192] An interference test is performed on the first transmission beam and the second transmission beam to obtain a second ratio and a third ratio. When the second ratio and the third ratio are less than a target threshold, it is determined that the interference between the first transmission beam and the second transmission beam is very small and can be ignored, and the scheduling time-frequency resources can overlap, and there is no need to perform interference avoidance, and spatial multiplexing can be performed;
[0193] When the second ratio and the third ratio are greater than or equal to the target threshold, it is determined that there is interference between the first transmission beam and the second transmission beam, the scheduled time-frequency resources cannot overlap, and interference avoidance is required.
[0194] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present invention.

As used below, the term "module" can implement a combination of software and / or hardware of a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

Since the interference relationship between the two transmission beams before receiving the terminal transmission request is pre-recorded in the beam interference relationship set, when a transmission request is received, it is only necessary to perform an acquisition operation from the pre-constructed beam interference relationship set to determine the situation of the target terminal corresponding to the first transmission beam for transmission beam selection and time-frequency resource scheduling according to the interference relationship recorded in the beam interference relationship set. In other words, the interference relationship between any two transmission beams can be determined in real time through the pre-constructed beam interference relationship set, without having to perform multiple repeated measurements based on the terminal served each time, thereby reducing the measurement resource overhead and measurement delay of the system.
