Transmission beam interference detection method, device, storage medium and electronic device
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This disclosure is based on and claims the priority of Chinese patent application No. 202310694204.9 filed on June 12, 2023, and all the disclosed contents are incorporated into this disclosure by reference. Technical Field
[0003] The embodiments of the present disclosure 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
[0004] In a distributed system, access nodes equipped with multiple antennas are generally required based on their geographical locations, connected to a central processing unit via high-speed backhaul links, or information exchange between multiple adjacent access nodes is achieved through high-speed links. Such a distributed system enables multiple access nodes on the network side to use the same time-frequency resources to achieve spatial multiplexing and 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 no longer follows the rule that transmission beams with similar directions have stronger interference in traditional cellular base stations. At the same time, the beam implementation methods on the terminal side of different manufacturers are different and unknown to the network side, which may cause different terminals to experience different levels of interference from the same transmission beam on the network side.
[0005] Therefore, the transmission beam interference relationships in distributed systems cannot be modeled on the patterns of traditional cellular base stations. This means that the interference relationship between any two transmission beams on the network side must be measured for each terminal served. As network access nodes become increasingly densely deployed, the number of access nodes and transmission beams within a cell increases significantly. Existing methods for measuring and managing interference for transmission beams result in a significant increase in system measurement resource overhead and latency.
[0006] In view of the problems in related technologies such as low detection efficiency of transmission beams, no effective solutions have been proposed yet.

[0030] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings and in conjunction with embodiments.
[0031] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0032] The method embodiments provided in the embodiments of the present disclosure can be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking operation on a mobile terminal as an example, FIG1 is a hardware structure block diagram of a mobile terminal according to a method for detecting interference of a transmission beam in accordance with an embodiment of the present disclosure. As shown in FIG1 , the mobile terminal may include one or more (only one is shown in FIG1 ) processors 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It will be understood by those skilled in the art that the structure shown in FIG1 is merely illustrative and does not limit the structure of the mobile terminal. For example, the mobile terminal may also include more or fewer components than those shown in FIG1 , or have a configuration different from that shown in FIG1 .
[0033] The memory 104 can be used to store computer programs, such as software programs and modules of application software, such as the computer program corresponding to the transmission beam interference detection method in the embodiment of the present disclosure. The processor 102 executes the computer program stored in the memory 104 to execute various functional applications and data processing, thereby implementing the above-mentioned method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include memory remotely located 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.
[0034] The transmission device 106 is used to receive or send data via a network. A specific example of the aforementioned network may include a wireless network provided by the mobile terminal's communications provider. In one embodiment, the transmission device 106 includes a network interface controller (NIC), which can be connected to other network devices via a base station to enable communication with the Internet. In another embodiment, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.
[0035] In this embodiment, a method for detecting interference of a transmission beam running on the mobile terminal is provided. FIG2 is a flow chart of detecting interference of a transmission beam according to an embodiment of the present disclosure. As shown in FIG2 , the flow chart includes the following steps:
[0036] Step S202: receiving a transmission request in a transmission network, wherein the transmission request is used to indicate that a 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;
[0037] 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;
[0038] Step S206: Detect the 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.
[0039] Through the above steps, upon receiving a transmission request from a target terminal requesting data transmission using a first transmission beam 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. Then, based on the interference relationship between the first transmission beam and each second transmission beam in the transmission beam set, the target interference relationship between the first transmission beam and the transmission network is detected. Because the beam interference relationship set pre-records the interference relationships between multiple transmission beams prior to receiving the terminal's transmission request, upon receiving a transmission request, only the pre-established beam interference relationship set needs to be retrieved to determine, based on the interference relationships recorded in the beam interference relationship set, the transmission beam selection and time-frequency resource scheduling for the target terminal corresponding to the first transmission beam. In other words, the pre-established beam interference relationship set can be used to determine the interference relationship between any two transmission beams in real time, eliminating the need for repeated measurements for each terminal served. This reduces the system's measurement resource overhead and measurement latency. Therefore, the problem of low transmission beam detection efficiency can be addressed, thereby improving the efficiency of transmission beam detection.
[0040] For example, in this embodiment, the execution entity of the above-mentioned transmission beam interference detection method may be, but is 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 is not limited to, applied in millimeter wave communication systems, 5G NR (5th Generation New Radio) systems, etc.
[0041] For example, in this embodiment, since the MIMO (Multiple Input Multiple Output) transmission technology of multi-antenna transmission and multi-antenna reception can not only fully utilize spatial dimension resources, but also improve spectrum efficiency and energy efficiency, the above-mentioned transmission beam interference detection method can be, but is not limited to, used in an environment where the MIMO transmission technology of multi-antenna transmission and multi-antenna reception is used as a 5G NR technology. With the rapid growth of communication demand, base stations are deployed more and more densely. The above-mentioned transmission beam interference detection method can be, but is not limited to, applied in an environment where the large-scale antenna system on the network side is developing from centralized to distributed.
[0042] For example, in this embodiment, in actual network deployment, the above-mentioned transmission beam interference detection method can be applied, but is not limited to, in a system including a network-side central processing unit, an access node, and a terminal. For example, taking the application in a 5G NR system as an example, the network-side central processing unit is a baseband processing unit (BBU), and the access node is an active antenna unit (AAU). Alternatively, the central processing unit is a centralized unit (CU), and the access node is a radio unit (RU). Alternatively, the central processing unit is a distributed unit (DU), and the like.
[0043] In the technical solution provided in step S202 above, the transmission network may be, but is not limited to, an information transmission system consisting of network-side central processing units, access nodes, and terminals within a certain area. The central processing units and terminals may, but are not limited to, interact via access nodes. For example, central processing units, access nodes, and terminals within the same cell may be defined as a single transmission network. Alternatively, central processing units, access nodes, and terminals within a specific range may be defined as a single transmission network.
[0044] For example, in this embodiment, the target terminal may be, but is not limited to, a terminal device whose transmission beam in the transmission network has changed. For example, a new target terminal has been added to the transmission network and requests to use the transmission beam in the transmission network. Alternatively, the target terminal may be a target terminal that was previously in a silent state in the transmission network and requests to reconnect to the transmission network. Alternatively, a target terminal that has changed in the transmission network may be a target terminal that was previously using transmission beam A for data transmission and requests to use transmission beam B for data transmission.
[0045] For example, in this embodiment, it is possible but not limited to adding a new target terminal to the transmission network by sending a request to the access node corresponding to the target terminal in the transmission network. For example, when the target terminal needs to connect to the network, the target terminal sends a connection request to its corresponding access node; after the access node receives the connection request sent by the target terminal, it performs identity authentication and permission verification on the request, and decides whether to allow the target terminal device to enter the transmission network based on the verification results.
[0046] Illustratively, in this embodiment, each device in the above-mentioned transmission network can communicate through, but is not limited to, beams.
[0047] Exemplarily, in this embodiment, the access nodes and terminal devices in the above-mentioned transmission network may, but are not limited to, have the option of multiple beams, that is, the device terminal can not only receive the beams emitted by the access node corresponding to it, but also receive the beams emitted by the access nodes adjacent to or close to it.
[0048] Exemplarily, in this embodiment, the above-mentioned target terminal may, but is not limited to, transmit data to the access node corresponding thereto through a first transmission beam. The above-mentioned first transmission beam may, but is not limited to, be a transmission beam allocated by the access node to the target terminal that has changed in the transmission network.
[0049] Illustratively, in this embodiment, the transmission network may include, but is not limited to, multiple transmission beams. The multiple transmission beams have unique numbers, and the serial numbers of the transmission beams may be, but are not limited to, uniformly compiled.
[0050] Exemplarily, in this embodiment, the above-mentioned transmission request may be, but is not limited to, issued by the target terminal, the above-mentioned transmission request may be, but is not limited to, issued in the form of a beam, and the target terminal may, but is not limited to, requesting to use the first transmission beam among multiple transmission beams in the transmission network to transmit data by issuing a transmission request.
[0051] In an exemplary embodiment, a method for determining an interference situation is provided. Taking a transmission network including a central processing unit on the network side, multiple terminals, and access nodes corresponding to the terminals as an example, whether a target terminal needs to avoid interference can be determined by, but is not limited to, the following methods:
[0052] When the network side receives information about the changed transmission requirements of the target terminal, the access node associated with the target terminal, and the first transmission beam requested by the target terminal, a decision on scheduling resources required for the target terminal to use the first transmission beam needs to take into account the interference relationship between the first transmission beam and all transmission beams currently being served in the transmission network;
[0053] If there is mutual interference between the first transmission beam associated with the target terminal to be scheduled and other transmission beams being served by the current cell, the scheduled time-frequency resources cannot overlap and interference avoidance is required;
[0054] If the mutual interference between the first transmission beam associated with the target terminal to be scheduled and other transmission beams being served by the current cell is small and negligible, the scheduled time-frequency resources can be overlapped, and spatial multiplexing can be performed without interference avoidance.
[0055] In an exemplary embodiment, before the transmission request in the receiving transmission network is received, the beam interference relationship set can be obtained in the following manner, but is not limited to: obtaining an interference parameter set corresponding to each initial terminal to obtain one or more interference parameter sets, wherein the initial terminal is the terminal served by the transmission network before receiving the transmission request, and the interference parameter set includes one or more interference parameters, and the interference parameter is used to indicate the relationship between the transmission measurement value of the third transmission beam reported by the initial terminal and the transmission measurement value of the fourth transmission beam reported by the initial terminal, the fourth transmission beam is the transmission beam used by the initial terminal, and the third transmission beam is each other transmission beam in the multiple transmission beams except the fourth transmission beam; determining the number of interferences and the number of multiplexings between each of the multiple transmission beams according to the relationship between each interference parameter in the one or more interference parameter sets and the interference parameter threshold; determining the interference probability and the multiplexing probability between each of the multiple transmission beams according to the number of interferences and the number of multiplexings between the multiple transmission beams to obtain the beam interference relationship set.
[0056] Exemplarily, in this embodiment, the above-mentioned initial terminal may include, but is not limited to, terminal devices in the transmission network other than the target terminal that has changed. For example, the initial terminal may be, but is not limited to, a terminal device that is in use in the transmission network before receiving a transmission request in the transmission network.
[0057] Exemplarily, in this embodiment, the above-mentioned transmission network may include, but is not limited to, multiple initial terminals, and may obtain, but is not limited to, an interference parameter set corresponding to each terminal device in the initial terminal by determining the interference conditions between each pair of initial terminals. For example, taking the transmission network including initial terminal A, initial terminal B and initial terminal C as an example, the interference parameter set of initial terminal A includes the interference condition between initial terminal A and initial terminal B and the interference condition between initial terminal A and initial terminal C.
[0058] Exemplarily, in this embodiment, the transmission beam used by the initial terminal may be determined as, but not limited to, the fourth transmission beam, and each transmission beam in the transmission network except the fourth transmission beam may be determined as, but not limited to, the third transmission beam.
[0059] Illustratively, in this embodiment, the interference parameter may be, but is not limited to, used to indicate interference between the fourth transmission beam used by the initial terminal and other transmission beams received by the initial terminal.
[0060] Exemplarily, in this embodiment, it is possible but not limited to determining each transmission beam in the transmission network except the fourth transmission beam as the third transmission beam in turn, and then calculating the interference parameters of the fourth transmission beam of the initial terminal relative to the third transmission beam in turn, to obtain a set of interference parameters of the fourth transmission beam of the initial terminal relative to each transmission beam except the fourth transmission beam.
[0061] For example, in this embodiment, the transmission measurement value of the third transmission beam may be, but is not limited to, used to indicate an average value of the signal power received on all REs (resource elements) carrying the third transmission beam within a symbol. For example, the RSRP value (Reference Signal Receiving Power) of the third transmission beam reported by the initial terminal.
[0062] For example, in this embodiment, the transmission measurement value of the fourth transmission beam may be, but is not limited to, used to indicate an average value of the signal power received on all REs (resource elements) carrying the fourth transmission beam within a symbol. For example, the RSRP value of the fourth transmission beam reported by the initial terminal.
[0063] Exemplarily, in this embodiment, the RSRP value of the third transmission beam reported by the initial terminal can be determined as the transmission measurement value of the third transmission beam, but is not limited to, and the RSRP value of the fourth transmission beam reported by the initial terminal can be determined as the transmission measurement value of the fourth transmission beam, but is not limited to.
[0064] Exemplarily, in this embodiment, the ratio between the RSRP value of the third transmission beam reported by the initial terminal and the RSRP value of the fourth transmission beam can be determined as the interference parameter between the third transmission beam and the fourth transmission beam, and each transmission beam in the transmission network except the fourth transmission beam is determined as the third transmission beam in turn, and the interference parameters of the fourth transmission beam of the initial terminal relative to each third transmission beam are calculated in turn, so as to obtain the interference parameter set of the fourth transmission beam of the initial terminal relative to each transmission beam except the fourth transmission beam.
[0065] For example, in this embodiment, the interference parameter threshold may be, but is not limited to, predetermined and used to count the number of interferences and the number of multiplexings in the interference parameter set. For example, the number of interference parameters in the interference parameter set that are greater than or equal to the interference parameter threshold may be counted as the number of interferences. Alternatively, the number of interference parameters in the interference parameter set that are less than the interference parameter threshold may be counted as the number of multiplexings, but is not limited to being counted.
[0066] Exemplarily, in this embodiment, the above-mentioned number of interferences can be, but is not limited to, used to indicate the number of times that interference occurs between the third transmission beam and the fourth transmission beam in the interference parameter set, and can be, but is not limited to, taking the number of interference parameters in the interference parameter set that are greater than or equal to the interference parameter threshold as the number of interferences.
[0067] Exemplarily, in this embodiment, the above-mentioned multiplexing times can be, but are not limited to, used to indicate the number of times the third transmission beam and the fourth transmission beam in the interference parameter set are multiplexed, and can be, but are not limited to, taking the number of interference parameters in the interference parameter set that are less than the interference parameter threshold as the multiplexing times.
[0068] Exemplarily, in this embodiment, the above-mentioned interference probability can be but is not limited to the proportion of the number of interference times in the interference parameter set, for example: the number of interference parameters in the interference parameter set that are greater than or equal to the interference parameter threshold is counted as the number of interference times, and then the ratio of the number of interference times to the number of all interference parameters in the interference parameter set is calculated to obtain the interference probability.
[0069] Exemplarily, in this embodiment, the above-mentioned multiplexing probability can be but is not limited to the proportion of the number of multiplexing times in the interference parameter set, for example: the number of interference parameters in the interference parameter set that are less than the interference parameter threshold is counted as the number of multiplexing times, and then the ratio of the number of multiplexing times to the number of all interference parameters in the interference parameter set is calculated to obtain the multiplexing probability.
[0070] Exemplarily, in this embodiment, the above-mentioned beam interference relationship set may include, but is not limited to, the interference probability and multiplexing probability between every two transmission beams in the transmission network. For example, the transmission network includes transmission beam A and transmission beam B, and the beam interference relationship set may include, but is not limited to, the interference probability and multiplexing probability between transmission beam A and transmission beam B, as well as the interference probability and multiplexing probability between transmission beam B and transmission beam A.
[0071] In an exemplary embodiment, the interference parameter set corresponding to each initial terminal can be obtained in the following manner, but is not limited to: initiating a periodic beam scan to the initial terminal; receiving multiple reference signal received power RSRP values reported by the initial terminal in response to the periodic beam scan within a target time length; calculating a first ratio of a first type of RSRP value to a second type of RSRP value in the multiple RSRP values to obtain the interference parameter set, wherein the first type of RSRP value is the RSRP value when the transmitting beam is the third transmission beam but the receiving beam is the fourth transmission beam, and the second type of RSRP value is the RSRP value when both the transmitting beam and the receiving beam are the fourth transmission beam, and the interference parameter set also includes a first default value, and the ratio of the third transmission beam that has not reported the RSRP value to the fourth transmission beam is set to the first default value.
[0072] Exemplarily, in this embodiment, the above-mentioned periodic beam scanning can be, but is not limited to, initiated by the central processing unit on the network side, and is used to instruct the terminal to report the corresponding RSRP value in response to the periodic beam scanning. For example, the network side initiates a periodic beam scanning process, and the terminals included in the transmission network perform polling measurements on the beam pairs corresponding to the transmitting beam of the access node and the receiving beam corresponding to the terminal, and feed back the corresponding RSRP value of each beam pair to the network side.
[0073] Exemplarily, in this embodiment, the interference parameter set may include, but is not limited to, a first type of RSRP value, a second type of RSRP value, and a first default value.
[0074] Exemplarily, in this embodiment, the above-mentioned first type of RSRP value is used to indicate the RSRP value of the third transmission beam of the access node based on the initial terminal and the fourth transmission beam corresponding to the initial terminal. That is, in the first type of RSRP value, the transmitting beam of the initial terminal based on the access node is each transmission beam in the transmission network except the fourth transmission beam corresponding to the initial terminal (i.e., the third transmission beam), and the receiving beam corresponding to the initial terminal is the fourth transmission beam.
[0075] Exemplarily, in this embodiment, the above-mentioned second type of RSRP value is used to indicate the RSRP value of the fourth transmission beam of the initial terminal based on the access node and the fourth transmission beam corresponding to the initial terminal, that is, in the second type of RSRP value, the transmitting beam of the initial terminal based on the access node is the fourth transmission beam corresponding to the initial terminal, and the receiving beam corresponding to the initial terminal is also the fourth transmission beam.
[0076] Exemplarily, in this embodiment, the ratio of each first-type RSRP value to the second-type RSRP value is calculated to obtain the interference parameter set.
[0077] Exemplarily, in this embodiment, the first default value is a ratio of the third transmission beam that does not report an RSRP value to the fourth transmission beam in the transmission network.
[0078] In an exemplary embodiment, based on the relationship between each of the interference parameters in the one or more interference parameter sets and the interference parameter threshold, the number of interferences and the number of multiplexings between each of the multiple transmission beams can be determined in the following manner, but is not limited to: the number of interference parameters in the interference parameter set that are greater than or equal to the interference parameter threshold is determined as the number of interferences between the fourth transmission beam and the third transmission beam; the number of interference parameters in the interference parameter set that are less than the interference parameter threshold is determined as the number of multiplexings between the fourth transmission beam and the third transmission beam.
[0079] Exemplarily, in this embodiment, the above-mentioned interference parameter set includes multiple interference parameters, and the number of interferences and the number of multiplexing between the fourth transmission beam and the third transmission beam can be determined by, but not limited to, determining the relationship between each interference parameter included in the interference parameter set and the interference parameter threshold.
[0080] In an exemplary embodiment, a method for determining the number of interferences and the number of multiplexings is provided. FIG3 is a flow chart of a process for determining the number of interferences and the number of multiplexings according to an embodiment of the present disclosure. As shown in FIG3 , taking a transmission network including a central processing unit on the network side, multiple terminals, and access nodes corresponding to the terminals as an example, the number of interferences and the number of multiplexings between two of the multiple transmission beams can be determined, but is not limited to, by the following method:
[0081] For the terminal that is currently transmitting data (initial terminal), the access node serving the terminal can calculate the RSRP value of each beam pair fed back by the terminal according to the formula (but not limited to) i, j = 1, ..., M, i ≠ j Calculate the RSRP values of other beam pairs in the transmission network (RSRP values of the first type) P j The RSRP value of the current transmission beam pair (the second type of RSRP value) Pi The interference parameter λ is obtained by the ratio of i,j , where M is used to indicate the total number of transmission beams of all access nodes in the same transmission network on the network side. The serial numbers of all transmission beams are compiled uniformly, i is used to indicate the serial number of the transmission beam (the fourth transmission beam) of the access node currently serving the terminal, and j is used to indicate the serial number of the third transmission beam.
[0082] For the network-side transmission beam (the fourth transmission beam) that does not report the RSRP value, the interference parameter of the fourth transmission beam is set to the first default value λ i,m =0,i,m=1,...,M,i≠m, the access node transmits the M ratio information to the central processing unit on the network side, and the central processing unit establishes and maintains the interference relationship between each transmission beam and any other transmission beam of all access nodes belonging to the same transmission network on the network side.
[0083] In the time interval W before the current moment, the interference parameter of each transmission beam is compared with the interference parameter threshold T. The number of interferences and the number of multiplexings between each beam and other beams can be updated by, but not limited to, the following method. Let the number of interferences be and reuse times The initial values are:
[0084] In the disturbance parameter λ i,j When the number of interferences is greater than or equal to the interference parameter threshold T, Add 1:
[0085] In the disturbance parameter λ i,j When the interference parameter threshold T is less than the number of multiplexing times Add 1:

[0087] In an exemplary embodiment, the interference probability and the multiplexing probability between any two of the multiple transmission beams can be determined based on the number of interferences and the number of multiplexings between any two of the multiple transmission beams in the following manner, but is not limited to: the ratio of the number of interferences to the number of interference parameters in the interference parameter set is determined as the interference probability; the ratio of the number of multiplexings to the number of interference parameters in the interference parameter set is determined as the multiplexing probability; wherein the beam interference relationship set also includes the interference probability and the multiplexing probability between the fifth transmission beam and the sixth transmission beam, the fifth transmission beam being a transmission beam that has not received any terminal reporting information during the periodic beam scanning process, and the sixth transmission beam being each transmission beam other than the fifth transmission beam in the multiple transmission beams.
[0088] For example, in this embodiment, the beam interference relationship set may include, but is not limited to, the interference relationship between the fourth transmission beam of the initial terminal and other transmission beams, and the interference relationship between the fifth transmission beam for which no terminal reporting information has been received in the transmission network and each transmission beam other than the fifth transmission beam. The beam interference relationship set may be, but is not limited to, an N*N table or an N*N matrix.
[0089] In an exemplary embodiment, a method for calculating interference probability and reuse probability is provided, where the number of interferences in the transmission network is and the number of reuses is For example, the interference probability and multiplexing probability between two of the multiple transmission beams included in the transmission network can be determined in the following manner, but is not limited to:

[0092] If no terminal of the i-th transmission beam reports corresponding information within a time interval of W before the current moment, the interference probability and multiplexing probability between the i-th transmission beam and other transmission beams are set to initial values.
[0093] In an exemplary embodiment, a method for constructing a beam interference relationship set is provided. FIG4 is a schematic diagram of a method for constructing a beam interference relationship set according to an embodiment of the present disclosure. As shown in FIG4 , taking a transmission network including two access nodes connected to a central processing unit via a high-speed link, each access node having two transmission beams, and a total of four transmission beams in the transmission network as an example, the interference relationship between each of the multiple transmission beams can be determined before receiving a transmission request, but is not limited to the following method:
[0094] Step 1: Within a time interval of W = 10 minutes before the current moment, the central processing unit initiates a periodic beam scanning process, and the terminal polls and measures the beam pairs corresponding to the transmitting beam of the access node and the corresponding receiving beam of the terminal. A total of 10 terminals respond to the periodic beam scanning and report the corresponding RSRP values of each beam pair.
[0095] Step 2: The access node calculates the RSRP value of each beam pair fed back by the current serving terminal (initial terminal) according to the formula Calculate the RSRP value P of other beam pairs j (RSRP value of the first type: the transmitting beam is the third transmission beam but the receiving beam is the fourth transmission beam) and the RSRP value P of the current transmission beam pair i The ratio λ between (RSRP values of the second type: both the transmit beam and the receive beam are the fourth transmission beam) i,j , and the RSRP values of other beam pairs P j RSRP value P of the current transmission beam i The ratio λ i,j Determine as interference parameter, where M=4, M is used to indicate the total number of transmission beams of all access nodes belonging to the same transmission network. The serial numbers of all transmission beams can be, but are not limited to, uniformly compiled. i represents the serial number of the transmission beam (the fourth transmission beam) corresponding to the current service terminal, and j is used to indicate the serial number of the third transmission beam. For the network-side transmission beam (the fourth transmission beam) corresponding to which no RSRP value is reported, the interference parameter can be, but is not limited to, set to the first default value λ i,m =0,i,m=1,...,M,i≠m, then the access node transmits M=4 ratio information to the central processing unit on the network side as an interference parameter set.
[0096] Step 3: Set the interference parameter threshold T to T = -6dB, the number of interferences and reuse times The initial value is set to 0 Each interference parameter λ i,jCompare with the interference parameter threshold T, and update the number of interference times and the number of multiplexing times according to the comparison result. The specific process is as follows:

[0098] The number of interference parameters in the interference parameter set that are less than the interference parameter threshold T is counted, according to the formula The number of interference parameters in the interference parameter set that are less than the interference parameter threshold T is determined as the number of multiplexing times
[0099] The number of interferences and multiplexing times between two of the multiple transmission beams are obtained.
[0100] Step 4: Calculate the corresponding interference probability α based on the number of interferences and the number of multiplexing i,j and reuse probability β i,j , set the initial values of interference probability and reuse probability to 0.5 (α i,j =0.5,β i,j =0.5), according to the formula Calculate the interference probability and multiplexing probability between each of the multiple transmission beams.

[0109] The interference probability between transmission beam 3 and transmission beam 4 is 1, and the multiplexing probability is 0; the interference probability between transmission beam 4 and transmission beam 3 is 1, and the multiplexing probability is 0.
[0110] In an exemplary embodiment, a process for constructing a beam interference relationship set is provided. FIG5 is a second schematic diagram of a method for constructing a beam interference relationship set according to an embodiment of the present disclosure. As shown in FIG5 , taking a cell as a transmission network, the transmission network includes two access nodes, the access nodes are connected to a central processing unit via a high-speed link, each access node has two transmission beams, and there are a total of four transmission beams in the cell for communication services, for example, before receiving a transmission request, the interference relationship between each of the multiple transmission beams can be determined, but is not limited to, in the following manner:
[0111] Step 1: Within a time interval of W = 10 minutes before the current moment, the network side (central processing unit) initiates a periodic beam scanning process. The terminal performs polling measurement based on the beam pair corresponding to the transmitting beam of the access node and the receiving beam corresponding to the terminal. One terminal responds to the periodic beam scanning measurement and reports the RSRP value of the beam pair to the network side, and the terminal can report the RSRP values of up to two beam pairs.
[0112] Step 2: The access node calculates the RSRP value of each beam pair fed back by the current serving terminal (initial terminal) according to the formula i,j=1,...,M,i≠j calculate the RSRP values P of other beam pairs respectively j (RSRP value of the first type: the transmitting beam is the third transmission beam but the receiving beam is the fourth transmission beam) and the RSRP value P of the current transmission beam pair i (RSRP value of the second type: both the transmitting beam and the receiving beam are the fourth transmission beam) ratio, and the RSRP values of other beam pairs P j RSRP value P of the current transmission beam i The ratio λ i,jDetermined as an interference parameter, where M=4 is used to indicate the total number of transmission beams of all access nodes belonging to the same cell on the network side. The serial numbers of all transmission beams can be, but are not limited to, uniformly compiled. i represents the serial number of the transmission beam (the fourth transmission beam) corresponding to the current serving terminal, and j is used to indicate the serial number of the third transmission beam. For the network-side transmission beam (the fourth transmission beam) corresponding to which no RSRP value is reported, its interference parameter can be, but is not limited to, set to the first default value λ i,m =0,i,m=1,...,M,i≠m, then the access node transmits M=4 ratio information to the central processing unit on the network side.
[0113] Step 3: The central processing unit establishes and maintains the interference relationship between each beam and any other beam in the transmission beams of all access nodes in the same cell on the network side. Set the interference parameter threshold T to T = -6dB, the number of interferences and reuse times The initial value is Each interference parameter λ i,j Compare with the interference parameter threshold T, and update the number of interference times and the number of multiplexing times according to the comparison result. The specific process is as follows:
[0114] The number of interference parameters in the interference parameter set that are greater than or equal to the interference parameter threshold T is counted, according to the formula The number of interference parameters in the interference parameter set that is greater than or equal to the interference parameter threshold T is determined as the number of interferences
[0115] The number of interference parameters in the interference parameter set that are less than the interference parameter threshold T is counted, according to the formula The number of interference parameters in the interference parameter set that are less than the interference parameter threshold T is determined as the number of multiplexing times
[0116] The number of interferences and multiplexing times between two of the multiple transmission beams are obtained.
[0117] Step 4: Calculate the corresponding interference probability α based on the number of interferences and the number of multiplexing i,j and reuse probability β i,j , set the initial values of interference probability and reuse probability to 0.5 (α i,j =0.5,β i,j =0.5), according to the formula Calculate the interference probability and multiplexing probability between each of the multiple transmission beams.
[0118] The interference relationship between each of the multiple transmission beams finally obtained by the central processing unit on the network side is shown in Table 2.
[0119] Table 2
[0120] As can be seen from Table 2, the beam interference relationship set includes the following:
[0121] The interference probability between transmission beam 1 and transmission beam 2 is 1, and the multiplexing probability is 0; the interference probability between transmission beam 2 and transmission beam 1 is 1, and the multiplexing probability is 0;
[0122] The interference probability between transmission beam 1 and transmission beam 3 is 0.5, and the multiplexing probability is 0.5; the interference probability between transmission beam 3 and transmission beam 1 is 0.5, and the multiplexing probability is 0.5;
[0123] The interference probability between transmission beam 1 and transmission beam 4 is 0.5, and the multiplexing probability is 0.5; the interference probability between transmission beam 4 and transmission beam 1 is 0.5, and the multiplexing probability is 0.5;
[0124] The interference probability between transmission beam 2 and transmission beam 3 is 0.5, and the multiplexing probability is 0.5; the interference probability between transmission beam 3 and transmission beam 2 is 0.5, and the multiplexing probability is 0.5;
[0125] The interference probability between transmission beam 2 and transmission beam 4 is 0.5, and the multiplexing probability is 0.5; the interference probability between transmission beam 4 and transmission beam 2 is 0.5, and the multiplexing probability is 0.5;
[0126] The interference probability between transmission beam 3 and transmission beam 4 is 0.5, and the multiplexing probability is 0.5; the interference probability between transmission beam 4 and transmission beam 3 is 0.5, and the multiplexing probability is 0.5.
[0127] In the technical solution provided in the above step S204, the reference interference relationship may include, but is not limited to, an interference relationship between the first transmission beam and each second transmission beam in the transmission beam set.
[0128] Exemplarily, in this embodiment, the second transmission beam may be, but is not limited to, each transmission beam in the transmission network except the first transmission beam.
[0129] Illustratively, in this embodiment, the interference relationship between the first transmission beam and each second transmission beam may be determined based on, but not limited to, interference parameters between the first transmission beam and each transmission beam in the transmission network except the first transmission beam.
[0130] Exemplarily, in this embodiment, the above-mentioned beam interference relationship set may be, but is not limited to, pre-constructed before receiving the transmission request, and the above-mentioned beam interference relationship set may be, but is not limited to, representing the interference relationship between each transmission beam in the transmission network and other transmission beams through the interference probability and multiplexing probability between each transmission beam in the transmission network and other transmission beams.
[0131] Illustratively, in this embodiment, the above-mentioned transmission beam set includes all transmission beams used in the current transmission network.
[0132] In an exemplary embodiment, the interference relationship between the first transmission beam and each second transmission beam in the transmission beam set can be obtained from the beam interference relationship set corresponding to the transmission network in the following manner, but is not limited to: obtaining a first interference probability and a second interference probability from the beam interference relationship set as the interference relationship between the first transmission beam and the second transmission beam, wherein the first interference probability is the interference probability of the first transmission beam to the second transmission beam, and the second interference probability is the interference probability of the second transmission beam to the first transmission beam.
[0133] For example, in this embodiment, the beam interference relationship set may include, but is not limited to, the interference relationship between each transmission beam in the transmission network and any other transmission beam. The interference relationship between each transmission beam in the transmission network and any other transmission beam may be represented by, but is not limited to, the interference probability between each transmission beam in the transmission network and any other transmission beam. Alternatively, the interference relationship between each transmission beam in the transmission network and any other transmission beam may be represented by, but is not limited to, the interference probability and multiplexing probability between each transmission beam in the transmission network and any other transmission beam.
[0134] For example, in this embodiment, the first interference probability includes the interference probability between the first transmission beam requested by the target terminal in the transmission network and each transmission beam other than the first transmission beam (i.e., the second transmission beam) in the transmission network. The second interference probability includes the interference probability between each transmission beam other than the first transmission beam in the transmission network and the first transmission beam requested by the target terminal in the transmission network. For example, assuming that the first interference probability is α i,j For example, the second interference probability is α j,i , where i is the transmission beam number of the first transmission beam in all transmission beams, j is the transmission beam number of the second transmission beam in all transmission beams, the first interference probability is the interference probability of the first transmission beam to the second transmission beam, and the second interference probability is the interference probability of the second transmission beam to the first transmission beam. The serial numbers of all transmission beams are compiled uniformly.
[0135] Exemplarily, in this embodiment, the interference relationship between the first transmission beam and the second transmission beam can be determined by, but not limited to, the interference probability between the first transmission beam requested to be used by the target terminal in the transmission network and each transmission beam in the transmission network except the first transmission beam, and the interference probability between each transmission beam in the transmission network except the first transmission beam and the first transmission beam requested to be used by the target terminal in the transmission network.
[0136] In an exemplary embodiment, the interference relationship between the first transmission beam and each second transmission beam in the transmission beam set can be obtained from the beam interference relationship set corresponding to the transmission network in the following manner, but is not limited to: obtaining a first multiplexing probability and a second multiplexing probability from the beam interference relationship set as the interference relationship between the first transmission beam and the second transmission beam, wherein the first multiplexing probability is the multiplexing probability of the first transmission beam to the second transmission beam, and the second multiplexing probability is the multiplexing probability of the second transmission beam to the first transmission beam.
[0137] For example, in this embodiment, the interference relationship between each transmission beam in the transmission network and other transmission beams may be represented by, but is not limited to, the multiplexing probability between each transmission beam and other transmission beams in the transmission network. Alternatively, the interference relationship between each transmission beam in the transmission network and other transmission beams may be represented by, but is not limited to, the interference probability and multiplexing probability between each transmission beam in the transmission network and other transmission beams in the transmission network.
[0138] Exemplarily, in this embodiment, the above-mentioned second transmission beam includes each transmission beam in the transmission network except the first transmission beam, and the first multiplexing probability is the multiplexing probability between the first transmission beam requested to be used by the target terminal in the transmission network and each transmission beam in the transmission network except the first transmission beam.
[0139] Illustratively, in this embodiment, the second multiplexing probability is a multiplexing probability between each transmission beam except the first transmission beam in the transmission network and the first transmission beam requested to be used by the target terminal in the transmission network.
[0140] Exemplarily, in this embodiment, the multiplexing relationship between the first transmission beam and the second transmission beam can be determined by, but is not limited to, the multiplexing probability between the first transmission beam requested to be used by the target terminal in the transmission network and each transmission beam in the transmission network except the first transmission beam, and the multiplexing probability between each transmission beam in the transmission network except the first transmission beam and the first transmission beam requested to be used by the target terminal in the transmission network.
[0141] In the technical solution provided in step S206 above, determining whether a terminal in the transmission network needs to perform transmission beam selection and time-frequency resource scheduling may be performed based on, but is not limited to, one or more reference interference relationships. For example, if the reference interference relationship determines that the mutual interference between the first transmission beam and the second transmission beam is negligible and minimal, then the scheduled time-frequency resources can overlap, eliminating the need for interference avoidance and enabling spatial multiplexing. Alternatively, if the reference interference relationship determines that there is a potential for mutual interference between the first transmission beam and the second transmission beam, then interference avoidance condition determination is required.
[0142] In an exemplary embodiment, the target interference relationship between the first transmission beam and the transmission network can be detected according to the one or more reference interference relationships in the following manner, but is not limited to: determining whether the spatial multiplexing condition is met between the first transmission beam and the second transmission beam corresponding to the reference interference relationship according to the first multiplexing probability and the second multiplexing probability included in each of the reference interference relationships, and a multiplexing probability threshold, wherein the first multiplexing probability is the multiplexing probability of the first transmission beam to the second transmission beam, and the second multiplexing probability is the multiplexing probability of the second transmission beam to the first transmission beam; When the spatial multiplexing conditions are met between the beams, the target interference relationship between the first transmission beam and the second transmission beam is determined as not requiring interference avoidance, and spatial multiplexing is allowed; when the spatial multiplexing conditions are not met between the first transmission beam and the second transmission beam corresponding to the reference interference relationship, the target interference relationship between the first transmission beam and the second transmission beam is determined based on the first interference probability and the second interference probability included in each of the reference interference relationships, and the interference probability threshold, wherein the first interference probability is the interference probability of the first transmission beam to the second transmission beam, and the second interference probability is the interference probability of the second transmission beam to the first transmission beam.
[0143] For example, in this embodiment, the multiplexing probability of the first transmission beam on the second transmission beam may be determined as the first multiplexing probability, but is not limited to the first multiplexing probability. The multiplexing probability of the second transmission beam on the first transmission beam may be determined as the second multiplexing probability, but is not limited to the second multiplexing probability.
[0144] Illustratively, in this embodiment, the multiplexing probability threshold may be, but is not limited to, predetermined and 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 may be 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] Exemplarily, 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.
[0146] For example, in this embodiment, the interference probability of the first transmission beam on the second transmission beam may be determined as the first interference probability, but is not limited to the first interference probability. The interference probability of the second transmission beam on the first transmission beam may be determined as the second interference probability, but is not limited to the second interference probability.
[0147] For example, in this embodiment, the interference probability threshold may be, but is not limited to, predetermined and used to indicate the 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 exemplary embodiment, a method for detecting a target interference relationship is provided. FIG6 is a schematic diagram of a method for detecting a target interference relationship according to an embodiment of the present disclosure. As shown in FIG6 , taking a cell as a transmission network, and transmission beam 1 of the current access node 1 of the cell performing communication services with terminal 1 as an example, a scheduling decision can be made for the resources required by transmission beam 4 to be scheduled associated with terminal 2 in the following manner, but is not limited to:
[0149] Step 1: While access node 1's transmission beam 1 is communicating with terminal 1, the network receives a transmission request from newly added terminal 2, which is associated with access node 2 and transmission beam 4. The network needs to make a scheduling decision for 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 then performs a conditional check between the transmission beam to be scheduled associated with the terminal and the transmission beam currently serving the cell.
[0150] Step 2: Set the reuse probability threshold to K reu = 0.9, perform spatial multiplexing condition judgment on the scheduled transmission beam 4 associated with the terminal and the transmission beam 1 currently being served by the current cell, and obtain the first multiplexing probability β of transmission beam 4 (first transmission beam) and transmission beam 1 (second transmission beam) from the pre-established 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) are β 4,1 =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 3: 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 terminal's transmission beam and schedules time-frequency resources based on the interference relationship between the terminal's associated transmission beam to be scheduled and all transmission beams currently serving the cell. After completing the judgment on interference avoidance and spatial multiplexing, the network performs the terminal's transmission beam selection and time-frequency resource scheduling.
[0153] In an exemplary embodiment, the target interference relationship between the first transmission beam and the second transmission beam can be determined based on the first interference probability and the second interference probability included in each reference interference relationship, and the interference probability threshold in the following manner, but is not limited to: determine whether the interference avoidance condition is met between the first transmission beam and the second transmission beam corresponding to the reference interference relationship based on the first interference probability and the second interference probability included in each reference interference relationship, and the interference probability threshold; if the interference avoidance condition is met between the first transmission beam and the second transmission beam corresponding to the reference interference relationship, determine that the target interference relationship between the first transmission beam and the second transmission beam requires interference avoidance; if the interference avoidance condition is not met between the first transmission beam and the second transmission beam corresponding to the reference interference relationship, perform an interference test on the target terminal to obtain the target interference relationship between the first transmission beam and the second transmission beam.
[0154] Exemplarily, in this embodiment, 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. 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 first transmission beam and the second transmission beam corresponding to the reference interference relationship do not satisfy the interference avoidance condition. 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 may be determined that the first transmission beam and the second transmission beam corresponding to the reference interference relationship satisfy the interference avoidance condition.
[0155] In an exemplary embodiment, a method for detecting a target interference relationship is provided. FIG7 is a second schematic diagram of a method for detecting a target interference relationship according to an embodiment of the present disclosure. As shown in FIG7 , a cell is taken as a transmission network. The cell currently has a transmission beam 2 of an access node 1 communicating with a terminal 1. At the same time, the network side receives a transmission request from a newly added terminal 2. For example, the newly added terminal 2 is associated with the access node 2 and the transmission beam 3. When the transmission request is received, the target interference relationship between the transmission beam 3 and the other transmission beams can be determined, but not limited to, in the following manner. The transmission request received by the network side from the newly added terminal 2 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 access node 1's transmission beam 2 communicating with terminal 1. Simultaneously, the network receives a transmission request from newly added terminal 2, which is associated with access node 2 and transmission beam 3. The network then makes a scheduling decision regarding the resources required for transmission beam 3 to be scheduled, which is associated with the terminal. The network then selects the access node and corresponding transmission beam to serve the terminal. The network then performs a conditional check between the transmission beam to be scheduled associated with terminal 2 and the transmission beam 2 currently serving the 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 (second transmission beam) and transmission beam 3 (first transmission beam) from the pre-established beam interference relationship set (Table 1), 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) are 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 Compared, 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 , so 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 scheduled transmission beam 3 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:
[0159] Assume that the interference probability threshold K inf K inf =0.7, perform interference avoidance condition judgment on the transmission beam 3 associated with the scheduled terminal 2 and the transmission beam 2 being served by the current cell, and obtain the reference interference relationship between transmission beam 2 (second transmission beam) and transmission beam 3 (first transmission beam) from the pre-established beam interference relationship set (Table 1). The reference interference relationship includes the first interference probability α between transmission beam 2 and transmission beam 3 2,3 (Interference probability of the first transmission beam on the second transmission beam) and the second interference probability α 3,2 (The interference probability of the second transmission beam on the first transmission beam) is α 2,3 =0.9,α 3,2 =0.9, according to the condition α m,n ≥K inf ,α n,m ≥K inf , determine that the interference avoidance condition is met between transmission beam 2 and transmission beam 3.
[0160] Step 4: There is mutual interference between the transmission beam to be scheduled associated with terminal 2 and other transmission beams being served by the current cell. The scheduling time-frequency resources cannot overlap, and interference avoidance is required.
[0161] Step 5: The network side selects the transmission beam and schedules time-frequency resources for terminal 2 after completing the judgment of interference avoidance and spatial multiplexing based on the interference relationship between the transmission beam to be scheduled associated with terminal 2 and all transmission beams being served by the current cell.
[0162] In an exemplary embodiment, the target terminal may be subjected to an interference test in the following manner, but is not limited to: performing an interference test on the target terminal; if the target terminal passes the interference test, determining that the target interference relationship between the first transmission beam and the second transmission beam is one that does not require interference avoidance, and allowing spatial multiplexing; if the target terminal fails the interference test, determining that the target interference relationship between the first transmission beam and the second transmission beam is one that requires interference avoidance.
[0163] For example, in this embodiment, the interference test may be used, but is not limited to, to determine a target interference relationship between the first transmission beam and the second transmission beam.

[0171] In an exemplary embodiment, a process for executing an interference test is provided. Figure 8 is a schematic diagram of a process for executing an interference test according to an embodiment of the present disclosure. As shown in Figure 8, access node 1 and access node 2 transmit to their respective terminals respectively. As shown in Figure 8(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 with by the transmission beams of adjacent access nodes. As shown in Figure 8(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. Taking the example of determining terminal 1 and terminal 2 as target terminals, the transmission beam emitted by terminal 1 as the first transmission beam, and the transmission beam emitted by terminal 2 as the second transmission beam, interference testing can be performed on terminal 1 and terminal 2 in the following manners, 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 transmission beams of the service access node measured by terminal 1 and terminal 2, and the RSRP values of the transmission beams of the adjacent nodes.
[0174] In an exemplary embodiment, a method for detecting a target interference relationship is provided. FIG9 is a schematic diagram of a method for detecting a target interference relationship according to an embodiment of the present disclosure. As shown in FIG9 , a cell is taken as a transmission network. The cell currently has access node 1 with transmission beam 1 communicating with terminal 1. At the same time, the network side receives a transmission request from a newly added terminal 2. For example, the newly added terminal 2 is associated with access node 2 and transmission beam 3. When the transmission request is received, the target interference relationship between transmission beam 3 and other transmission beams can be determined, but not limited to, in the following manner. The transmission request received by the network side from the newly added terminal 2 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: While access node 1's transmission beam 1 is communicating with terminal 1, the network (central processing unit) receives a transmission request from newly added terminal 2, which is associated with access node 2 and transmission beam 3. The network then makes a scheduling decision for the resources required for the scheduled transmission beam 3 associated with the terminal and selects the access node and corresponding transmission beam to serve the terminal. The network then performs a conditional check between the terminal's associated transmission beam 1 and the transmission beam currently serving the 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 currently being served by the current cell, and obtain the first multiplexing probability β between transmission beam 3 (first transmission beam) and transmission beam 1 (second transmission beam) from the pre-established 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) are 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] Let the interference probability threshold be K inf =0.7, perform interference avoidance condition judgment on transmission beam 3 (first transmission beam) associated with the scheduled terminal and transmission beam 1 (second transmission beam) currently being served by the current cell, and obtain the first interference probability α between transmission beam 2 and transmission beam 1 from the pre-established 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: Set the target threshold 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), the terminal measures and feeds back the RSRP value (Second RSRP value). The network side calculates the 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 of 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 perform interference avoidance, and spatial multiplexing can be performed.
[0181] Step 6: The network side selects the terminal's transmission beam and schedules time-frequency resources based on the interference relationship between the terminal's associated transmission beam to be scheduled and all transmission beams currently being served by the cell. After completing the judgment on interference avoidance and spatial multiplexing, the network performs the terminal's transmission beam selection and time-frequency resource scheduling.
[0182] Step 7: After terminal 2 accesses the network, the network side may iteratively update the interference relationship between transmission beams based on the relevant interference measurement results of terminal 2, but is not limited to iteratively updating the interference relationship between transmission beams.
[0183] In an exemplary embodiment, a transmission beam interference detection process is provided. FIG10 is a flowchart of a transmission beam interference detection process according to an embodiment of the present disclosure. As shown in FIG10 , the transmission beam interference detection can be performed by, but is not limited to, the following process:
[0184] An interference relationship set is pre-constructed, which includes an interference relationship between each transmission beam in the transmission network as a first transmission beam and each second transmission beam in the transmission beam set.
[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] Determining whether interference avoidance is required 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, no interference avoidance is required, and spatial multiplexing can be performed;
[0188] After determining that spatial multiplexing can be performed between the first transmission beam and the second transmission beam, 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 interference exists between the first transmission beam and the second transmission beam, the scheduled 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. If 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. The scheduled time-frequency resources can overlap, no interference avoidance is required, 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 interference exists 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 the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present disclosure is essentially 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, magnetic disk, optical disk), including a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present disclosure.
[0195] This embodiment also provides a transmission beam interference detection device, which is used to implement the above-mentioned embodiments and exemplary implementations. Details already described are omitted. As used below, the term "module" may refer to a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementation using hardware, or a combination of software and hardware, is also possible and contemplated.

[0198] A first acquisition module 1104 is configured to, 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;

Based on the interference relationship between the first transmission beam and each second transmission beam in the transmission beam set, the target interference relationship between the first transmission beam and the transmission network is detected. Because the beam interference relationship set pre-records the interference relationships between multiple transmission beams prior to receiving the terminal's transmission request, upon receiving a transmission request, only the pre-established beam interference relationship set needs to be retrieved to determine the transmission beam selection and time-frequency resource scheduling for the target terminal corresponding to the first transmission beam based on the interference relationships recorded in the beam interference relationship set. In other words, the pre-established beam interference relationship set can be used to determine the interference relationship between any two transmission beams in real time, eliminating the need for repeated measurements for each terminal served, thereby reducing system measurement resource overhead and measurement latency.
