Description

Technical Field

[0001] This application is filed based on a Chinese patent application with an application number of 202110621837.8 and an application date of June 3, 2021, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is incorporated herein by reference.

[0002] Embodiments of the present application relate to the technical field of communications, but are not limited thereto, and particularly relate to a beam processing method, a network device, a base station, and a computer-readable storage medium.

Background Art

[0003] In wireless communication, an electromagnetic wave signal is transmitted from a transmitting side, undergoes attenuation, and finally reaches a receiving side. However, the effect of the electromagnetic wave signal received by the receiving side is not good. For example, in wireless communication between a base station and a terminal, when the base station transmits an electromagnetic wave signal to the terminal, the terminal can only receive a part of the electromagnetic wave signal, and the other part of the electromagnetic wave signal may not be received by the terminal due to losses such as absorption and scattering. Similarly, when the terminal transmits an electromagnetic wave signal to the base station, the base station can only receive a part of the electromagnetic wave signal, and the other part of the electromagnetic wave signal may not be received by the base station due to losses such as absorption and scattering. In either case, the quality of wireless communication between the base station and the terminal is reduced, and the communication efficiency between the base station and the terminal is deteriorated.

Mode for Carrying Out the Invention

[0013] To make the object, technical solution and advantages of the present application clearer, the present application will be described in more detail below with reference to the drawings and embodiments. It should be noted that the specific embodiments described in this specification are only used for interpreting the present application and not for limiting the present application.

[0014] Note that the classification of functional modules is shown in the schematic diagram of the device, and the logical order is shown in the flowchart. However, in some cases, it may be classified differently from the modules in the device, or the steps shown or described may be executed in an order different from the order in the flowchart. Terms such as "first", "second", etc. in the specification, claims, and the foregoing drawings are not used to explain a specific order or priority, but are used to distinguish similar objects.

[0015] Embodiments of the present application provide a beam processing method, a network device, a base station, and a computer-readable storage medium. The network node can determine a first beam for guiding a signal from the first beam identification information. Thus, under the condition that the first beam is formed in the first time domain, the electromagnetic wave signal transmitted or received by the base station can be guided by the first beam. That is, the guidance for the electromagnetic wave signal can improve the reception amount of the target electromagnetic wave signal by the base station or the terminal, thereby improving the quality of its wireless communication and the wireless communication efficiency. Further, since the first time domain is determined from the beam formation time information representing the time when the network node forms a beam for guiding a signal, the network node can guide the signal at the corresponding time by forming the corresponding beam in the first time domain, avoiding incorrect guidance and the occurrence of signaling storms, which is advantageous for improving the wireless communication efficiency.

[0016] Hereinafter, with reference to the drawings, the embodiments of the present application will be further described.

[0017] As shown in FIG. 1, FIG. 1 is a schematic diagram of a network topology for executing a beam processing method according to an embodiment of the present application.

[0018] In the example of FIG. 1, the network topology includes a network node 100, a base station 200, and terminals 300. There may be multiple terminals 300, and each terminal 300 matches with the base station 200. That is, the base station 200 can transmit an electromagnetic wave signal to each terminal 300, and each terminal 300 can also transmit an electromagnetic wave signal to the base station 200 in the same way. In addition, the network node 100 has a communication capability to establish communication with the base station 200. For example, the network node 100 can receive communication content from the base station 200 or transmit communication content to the base station 200. In other words, the base station 200 and the network node 100 in this network topology can communicate with each other. The base station 200 may communicate with the network node 100, or may communicate with the network node via a control unit or a control center in the related network. Collectively, it is assumed that the base station 200 and the network node 100 communicate with each other.

[0019] In one embodiment, each terminal 300 may be referred to as an access terminal, a user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user device. For example, each terminal may be a mobile phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing devices connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network or a future network with 5G or above. However, in this embodiment, it is not particularly limited thereto.

[0020] In one embodiment, the base station 200, i.e., the communication base station, is a form of radio station, which refers to a radio transceiver that exchanges information with mobile phone terminals in a certain radio coverage area. The main function of the base station is to provide radio coverage, that is, to enable the transmission of radio signals between the wired communication network and the radio terminal. Specifically, in this embodiment, the base station 200 is used to enable wireless communication with the terminal.

[0021] In one embodiment, the network node 100 may have various configurations. The network node 100 may be an intelligent panel under various protocols compatible with the fourth-generation wireless communication technology or the fifth-generation wireless communication technology. This intelligent panel may include the communication function between the base station and the terminal, and at the same time, may integrate other performances such as algorithms and controls. It may be an integrated one. For example, practically, it may be a Reconfigurable Intelligent Surface (RIS) intelligent panel. Or, the network node 100 may integrate a storage function and may be any communication medium with a built-in or externally attached memory device. When communicating with the base station 200 and the terminal 300, it can store the corresponding communication content, and can also store information related to the network node 100. For example, it can store communication information from the base station 200, preset beams, operation mode information of the network node 100, and detection information for the beams in the network node 100, etc. In this embodiment, it is not particularly limited in this regard.

[0022] In one embodiment, the positional relationship between the network node 100, the base station 200, and the terminal 300 may be random. In this case, the relative positional relationships between the network node 100 and the base station 200, and between the network node 100 and the terminal 300 are indefinite. When there are multiple terminals 300, the positional relationships between the terminals 300 are not limited, so the relative positional relationships between the network node 100 and each terminal 300 are also indefinite.

[0023] In one embodiment, even if both the location information of the network node 100 and the location information of the base station 200 are determined, in this case, the relative positional relationship between the network node 100 and the base station 200 is fixed, and the beam of the network node 100 corresponding to the base station 200 is also constant.

[0024] Either the base station 200 or the network node 100 may include a memory and a processor. Here, the memory and the processor may be connected via a bus or other means.

[0025] The memory as a non-transitory computer-readable storage medium may store a non-transitory software program and a non-transitory computer-executable program. Further, the memory may include a non-transitory memory such as a high-speed random access memory, at least one magnetic disk storage device, a flash memory device, or other non-transitory solid-state storage devices. In some embodiments, the memory may include a memory disposed remotely from the processor, and such a remote memory may be connected to the processor via a network. Examples of the above network include, but are not limited to, the Internet, a corporate intranet, a local area network, a mobile communication network, and combinations thereof.

[0026] The network topologies and application scenarios described in the embodiments of the present application are for more clearly explaining the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Those skilled in the art can understand that as the network topologies evolve and new application scenarios emerge, the technical solutions provided in the embodiments of the present application can also be similarly applied to similar technical problems.

[0027] A person skilled in the art can understand that the network topology shown in FIG. 1 does not constitute a limitation on the embodiments of the present application, and it may include more or fewer components than shown, combine specific components, or include different arrangements of components.

[0028] In the network topology shown in FIG. 1, the base station 200 or the network node 100 may call the beam processing program stored therein respectively to execute the beam processing method.

[0029] Based on the structure of the above network topology, various embodiments of the beam processing method of the present application are proposed.

[0030] As shown in FIG. 2, FIG. 2 is a flowchart of a beam processing method according to an embodiment of the present application. This beam processing method can be applied to the network node in the embodiment shown in FIG. 1 and includes steps S100 to S300, but is not limited thereto.

[0031] Step S100: Obtain beam time domain information including first beam identification information transmitted by a base station and beam formation time information representing the time for a network node to form a beam to guide a signal.

[0032] In one embodiment, the first beam identification information and the beam time domain information may be obtained simultaneously, but this is not limited. The first beam identification information and the beam time domain information may be transmitted in various ways. For example, they may be transmitted by the base station, or may be transmitted by the base station via a control unit or a control center of the relevant network, and there is no particular limitation on this.

[0033] There is a certain relationship between the base station and the base station side. However, as the differences between them, the base station is a single device, and the beam is aligned with the base station to guide the communication signal between the base station and the terminal. In contrast, the base station side may include other devices and control units in addition to the base station. When the base station side communicates with the network node, the base station may communicate with the network node, or other devices and control units on the base station side may communicate with the network node, and there is no limitation in this regard.

[0034] In one embodiment, the first beam identification information is used to indicate the beam aligned with the terminal. When the network node acquires the first beam identification information, the network node and the terminal can cooperate via the beam identified by the first beam identification information. The beam formation time information can also be used to represent the time required to transmit a signal via the beam between the base station and the corresponding terminal, that is, it reflects the signal transmission between the base station and the terminal in a specific application scenario, and enables the network node to cooperatively guide the signal transmission between the base station and the terminal based on this application scenario.

[0035] Note that since one base station may correspond to different terminals respectively, there are multiple first beam identification information and multiple beam formation time information, and each set of first beam identification information and beam time area information may correspond to one terminal. In such a case, the network node acquires a set of first beam identification information and beam time area information. In this case, the network node may correspond to the base station and the terminal corresponding to this set of first beam identification information and beam time area information respectively. Since the cooperation between any terminal and the base station is the same, for the sake of no redundancy, hereinafter, the description of the related embodiments is basically carried out for the network node, the base station, and one terminal, but it is not limited thereto.

[0036] Step S200: Determine the first time area from the beam formation time information.

[0037] Step S300: Form a first beam for guiding a signal, determined by a network node from first beam identification information, in a first time domain.

[0038] In one embodiment, the network node can determine a first beam for guiding a signal from the first beam identification information. Thus, under the condition that the first beam is formed in the first time domain, an electromagnetic wave signal transmitted or received by a base station can be guided by the first beam. That is, the guidance for the electromagnetic wave signal can improve the reception amount of the target electromagnetic wave signal by the base station or the terminal, thereby improving the quality of the wireless communication and the wireless communication efficiency. Further, since the first time domain is determined from beam formation time information representing the time for the network node to form a beam for guiding a signal, the network node can guide a signal at the corresponding time by forming the corresponding beam in the first time domain, which can avoid incorrect guidance and the occurrence of signaling storms, and is advantageous for improving the wireless communication efficiency.

[0039] As shown in FIG. 3, when the first beam identification information further includes beam indication information for instructing the first beam to be aligned with a first terminal, step S300 includes, but is not limited to, step S310.

[0040] Step S310: Based on the first beam identification information, form a first beam for aligning with the first terminal in the first time domain.

[0041] In one embodiment, since the first beam identification information includes beam indication information for instructing the first beam to be aligned with the first terminal, when the network node acquires the first beam identification information, it can simultaneously determine the first beam and the first terminal with which the first beam is to be aligned. In that case, the electromagnetic wave signal between the first terminal and the base station can be guided by the first beam, thereby improving the wireless communication efficiency between the first terminal and the base station.

[0042] In one embodiment, the beam indication information can be implicitly indicated, such as explicitly and directly indicating that the first beam is to be used for alignment with the first terminal, or implicitly indicating by the arrangement position of the first beam identification information.

[0043] As shown in FIG. 4, step S300 includes, but is not limited to, steps S320 to S330.

[0044] Step S320: Obtain beam indication information indicating that the first beam is to be aligned with the first terminal, which is transmitted by the base station.

[0045] Step S330: Based on the first beam identification information and the beam indication information, form the first beam for alignment with the first terminal in the first time domain.

[0046] In one embodiment, since the beam indication information is used to indicate that the first beam is to be aligned with the first terminal, when the network node simultaneously obtains the first beam identification information and the beam indication information, it can determine the first beam and the first terminal with which the first beam is to be aligned. In that case, the electromagnetic wave signal between the first terminal and the base station can be guided by the first beam, thereby improving the wireless communication efficiency between the first terminal and the base station.

[0047] As shown in FIG. 5, the beam processing method further includes, but is not limited to, step S400.

[0048] Step S400: Form the second beam for alignment with the base station, which is determined by the network node based on the relative positional relationship between the network node and the base station, in the first time domain.

[0049] In one embodiment, by forming the second beam and aligning it with the base station, the network node guides the signal transmitted from the base station to the corresponding terminal, or guides the signal transmitted from the corresponding terminal to the base station, thereby improving the quality of the wireless communication between the base station and the corresponding terminal and improving these wireless communication efficiencies.

[0050] It is understood that there are two application scenarios for the guidance of the network node by the first beam and the second beam.

[0051] In the first application scenario, as shown in FIG. 6, the base station transmits the corresponding downlink electromagnetic wave signal to the terminal. Since the second beam is aligned with the base station, the signal transmitted by the base station can be guided to the network node based on the second beam, that is, the signal guided through the network node can be accessed. On the other hand, since the first beam is aligned with the terminal, the signal received by the network node and transmitted by the base station can be further guided to the terminal based on the first beam, thereby improving the signal reception amount by the terminal.

[0052] In the second application scenario, as shown in FIG. 7, the terminal transmits the corresponding uplink electromagnetic wave signal to the base station. Since the first beam is aligned with the terminal, the signal transmitted by the terminal can be guided to the network node based on the first beam, that is, the signal guided through the network node can be accessed. On the other hand, since the second beam is aligned with the base station, the signal received by the network node and transmitted by the terminal can be further guided to the base station based on the second beam, thereby improving the signal reception amount by the base station.

[0053] In one embodiment, since the first time domain is determined from beamforming time information that can represent the time corresponding to signal transmission between the base station and the terminal, the network node guides the corresponding beam in the first time domain in the case of signal transmission between the base station and the terminal, thereby avoiding incorrect guidance and the occurrence of a signaling storm, and improving the wireless communication efficiency.

[0054] When the base station or the terminal transmits an electromagnetic wave signal, if the first beam and the second beam have not been formed yet, the network node cannot properly guide the transmitted electromagnetic wave signal. Or, when the base station or the terminal finishes transmitting the electromagnetic wave signal, it indicates that there is no guiding target signal related between the base station and the terminal at that time. If the first beam and the second beam have not been timely canceled, that is, if the first beam is still aligned with the terminal and the second beam is still aligned with the base station, there may be incorrect guidance to unrelated signals. Or, under the time division condition, when the network node aligns different beams with different terminals and the beam switching is performed once after the signal guiding to the terminal is completed and a notification is made every time the beam is switched, frequent switching will cause a signaling storm. To avoid such a situation, by restricting the first beam and the second beam to be formed only in the first time domain, the network node performs the corresponding guidance only in the case of signal transmission between the base station and the terminal, and both the situation where the signal guidance is too late and the occurrence of incorrect guidance or signaling storm can be avoided, thereby improving the wireless communication efficiency between the base station and the terminal.

[0055] In one embodiment, the beamforming time information is N1 (N1 is any integer between 1 and 14) consecutive orthogonal frequency division multiplexing (OFDM) symbols, and One OFDM symbol, and N2 (where N2 is 2, 4, or 7) consecutive OFDM symbols, Two consecutive OFDM symbols, and another two consecutive OFDM symbols, One OFDM symbol, and another OFDM symbol that is separated from the one OFDM symbol by four OFDM symbols, Two first beam symbols respectively distributed on two consecutive slots, where the two first beam symbols have corresponding positions on their respective slots, and the first beam symbol includes one OFDM symbol and another OFDM symbol that is separated from the one OFDM symbol by four OFDM symbols, the two first beam symbols, The beamforming symbol includes at least one of the types above.

[0056] The beamforming symbol corresponds to expressing beamforming time information in the form of a symbol. By expressing the beamforming time in the form of a symbol, the beam switching delay can be reduced to the order of a symbol, that is, the communication delay caused by guiding the electromagnetic wave signal using the network node can be reduced. The beamforming symbol of this embodiment is set based on the OFDM technology. In the OFDM technology, the smallest frequency domain unit can be defined as a subcarrier, and the smallest time domain unit can be defined as an OFDM symbol. To facilitate the use of frequency domain resources, a resource block is also defined. One resource block is defined as a specific number of consecutive subcarriers, and a bandwidth part (BWP) is also defined. One bandwidth block is defined as a more specific number of consecutive resource blocks on one carrier. To facilitate the use of time domain resources, a slot is also defined. One slot is defined as a more specific number of consecutive OFDM symbols.

[0057] For each of the above beamforming symbols, each beamforming symbol can be applied to a specific scenario to provide services to the adapted channels, as shown in the example illustrated below. Example 1

[0058] In the case of N1 consecutive OFDM symbols, the time of this beamforming can provide services to the physical uplink shared channel (PUSCH) from the terminal to the base station. The transmission time of the PUSCH is for N1 consecutive OFDM symbols. That is, within the time of this beamforming, the network node forms the corresponding beam and guides the electromagnetic wave signal carrying the physical uplink shared channel from the terminal through the network node to the base station. Similarly, it can provide services to the physical downlink shared channel (PDSCH) occupying the time of N1 consecutive OFDM symbols, the physical downlink control channel (PDCCH) and the physical uplink control channel (PUCCH) occupying the time of N1 consecutive OFDM symbols, the transmission of the channel state information reference signal (CSI-RS) occupying the time of one OFDM symbol, the transmission of the CSI-RS occupying the time of two OFDM symbols, the transmission of the code division multiplexing type cdm8-FD2-TD4 CSI-RS occupying the time of four OFDM symbols, and the sounding reference signal (SRS) occupying the time of one to four OFDM symbols.

[0059] For the case of one OFDM symbol and N2 consecutive OFDM symbols, the time for this beamforming can provide services to the transmission channels of mini-sized slots. For example, one OFDM symbol can provide services to the PDCCH of a mini-sized slot, N2 consecutive OFDM symbols can provide services to the PDSCH of a mini-sized slot, or provide services to the PUSCH of a mini-sized slot.

[0060] For the case of two consecutive OFDM symbols and another two consecutive OFDM symbols, the time for this beamforming can provide services to the CSI-RS that occupies the time of four OFDM symbols. For example, two consecutive OFDM symbols can provide services to one set of OFDM symbols carrying CSI-RS, and another two consecutive OFDM symbols can provide services to another set of OFDM symbols carrying CSI-RS. Here, the four OFDM symbols carrying CSI-RS are composed of two sets of OFDM symbols, each containing two consecutive OFDM symbols.

[0061] For the case of one OFDM symbol and another OFDM symbol that is separated from the first OFDM symbol by four OFDM symbols, the time for this beamforming can provide services to the Tracking Reference Signal (TRS: Channel State Information Reference Signal for tracking). For example, one OFDM symbol can provide services to the OFDM symbol before the one carrying TRS, and another OFDM symbol can provide services to the OFDM symbol after the one carrying TRS. All the OFDM symbols carrying TRS contain two OFDM symbols, and the next OFDM symbol is separated from the previous one by four OFDM symbols.

[0062] In the case of two first beam symbols respectively distributed on two consecutive slots, the time of this beamforming can provide services to the TRS. For example, two OFDM symbols on the previous one slot provide services to two OFDM symbols on one slot carrying the TRS, two OFDM symbols on the subsequent one slot provide services to two OFDM symbols on another slot of the TRS, all OFDM symbols carrying the TRS are distributed on two consecutive slots, the TRS on each slot is carried at the same OFDM symbol position, and for all OFDM symbols carrying the TRS on each slot, one OFDM symbol is only four OFDM symbols away from another OFDM symbol.

[0063] Note that the related beams in the network node including the first beam and the second beam may be called a spatial domain filter or a combination of operating parameters of various operating units in the network node. That is, various beams of the network node correspond one-to-one with the spatial domain filters used by the network node, and one spatial domain filter may correspond to one beam. Or, each beam corresponds one-to-one with a combination of operating parameters of various operating units in the network node, and one combination of operating parameters may correspond to one beam.

[0064] Regarding the second beam, when the relative position between the network node and the base station is fixed, the second beam may specifically be determined from several beams preset by the network node, but is not limited thereto.

[0065] In one embodiment, since the relative positions between the network node and the base station are fixed, when the position of the network node is determined, the corresponding position of the base station is directly determined based on this information, and the fixed beam for aligning with the base station is directly determined. Under this condition, it is not necessary to form the corresponding beam based on the first time domain, but it is directly determined from the preset beams. The network node can align with the base station based on the fixed beam to realize signal guidance, simplify the execution steps of the network node, and save network resources.

[0066] Regarding the second beam, when the relative positions between the network node and the base station are not fixed, the second beam may specifically be determined by the network node from the second beam identification information transmitted by the base station, but is not limited thereto.

[0067] In one embodiment, since the relative positions between the network node and the base station are not fixed, the network node cannot determine the position of the base station. Therefore, it cannot align with the base station based on the fixed beam. Under this condition, similar to obtaining the first beam identification information, the second beam is determined by the second beam identification information transmitted by the base station, and the network node can align with the base station based on the second beam to realize signal guidance.

[0068] In the example of FIG. 8, when the beam time domain information further includes beam formation slot information representing the period of beam formation, step S300 includes step S340, but is not limited thereto.

[0069] Step S340: Periodically form the first beam in the first time domain based on the beam formation slot information.

[0070] In one embodiment, the beamforming slot information is used to represent the period of beamforming. That is, the time of beamforming is periodic and described in slot units, and the beam may be formed on the bias slot within each period. For example, the beam may be formed on all OFDM symbols on the bias slot of each period, or on a specific OFDM symbol on the bias slot of each period, or on a negotiated OFDM symbol on the bias slot of each period, or on an OFDM symbol pre-specified by the base station on the bias slot of each period, or on an OFDM symbol pre-determined by the network node on the bias slot of each period.

[0071] In one embodiment, the network node can periodically form the first beam in the first time domain by acquiring the beamforming slot information. When the network node acquires the second beam identification information, it is also possible to periodically form the second beam in the first time domain. For example, in actual applications, when the base station transmits the beamforming slot information to the network node, the base station does not need to transmit the first beam identification information to the network node multiple times. Even if the base station notifies the network node of the first beam identification information only once, the network node can form the corresponding first beam multiple times based on the beamforming slot information. Also, since the first beam is formed only within the bias slot of each period, the remaining time within each period can be allocated to form additional beams that require alignment to other terminals for the remaining services, for example, which is advantageous for improving the operating efficiency of the network node.

[0072] In the example of FIG. 9, step S300 includes, but is not limited to, steps S350 to S360.

[0073] Step S350: Acquire the beamforming trigger information transmitted by the base station, including the first time interval.

[0074] Step S360: Form the first beam and the second beam in the first time domain according to the first time interval.

[0075] In one embodiment, the beamforming trigger information is used for the base station to perform a trigger operation. That is, the base station notifies the network node by using the formation of the corresponding beam and the time point of forming the corresponding beam as a trigger. Here, the time point of beamforming may be determined from the time point of triggering beamforming, or the time point of beamforming may be determined from the time point of triggering beamforming and the set first time interval. In addition to transmitting the beamforming trigger information, the triggering method may include, but is not limited to, notifying a trigger event, transmitting a trigger signaling, transmitting a trigger signal, or generating a trigger event. Let the time point of triggering beamforming be Ta, the time point of beamforming be Tb, and the first time interval be Tf. Then, the value of Tb can be determined from the value of Ta, and there is a relationship of Tb = Ta + Tf between them. Here, the first time interval may be configured by the base station itself, may be determined by the network node according to the actual application scenario and reported to the base station, or may be predetermined by the protocol. For example, the first time interval may be configured by the base station, may be notified to the network node by the configured beamforming trigger information, the beamforming trigger information may include the first time interval, and the time point of triggering beamforming is the time point of transmitting the beamforming trigger information.

[0076] In one embodiment, due to the influence of the beamforming trigger information, when the time point of triggering beamforming is determined, the time point of beamforming can be determined. Therefore, in the actual application scenario, the network node can accurately form the first beam and the second beam at a specific time point in the first time domain by receiving the specific beamforming trigger information transmitted by the base station. This specific time point is the time point required by the current scenario and can meet the time domain requirements for forming the corresponding beam in the current scenario.

[0077] In one case, the time when the base station transmits the beamforming trigger information is the time when the network node receives the beamforming trigger information. Therefore, the base station can indirectly indicate the time when it transmits the beamforming trigger information by transmitting the beamforming trigger information.

[0078] Note that when the beamforming time is determined from the time that triggers beamforming, it is not necessary to consider the influence of the first time interval. For example, the base station triggers the formation of the beam corresponding to the network node at time Ta, and the network node forms the corresponding beam at time Tb, etc., which may be set according to the actual situation. Here, time Tb is determined from time Ta.

[0079] In the example of FIG. 10, the beam processing method further includes, but is not limited to, steps S500 to S700.

[0080] Step S500: Transmit the beam operation mode supported by the network node to the base station.

[0081] Step S600: Obtain the first indication information transmitted by the base station according to the beam operation mode.

[0082] Step S700: Determine and apply the first beam operation mode from the first indication information based on the beam operation mode supported by the network node.

[0083] In one embodiment, the network node can understand the base station's instruction for a specific operating mode of the network node by acquiring the first instruction information transmitted by the base station. In an actual application scenario, the operating mode of the network node can be controlled by controlling the first instruction information transmitted by the base station. This provides a method for controlling the operating mode of the network node, thereby effectively adjusting the operating mode of the network node without controlling the network node itself, and optimizing the control flow of the network node.

[0084] In one embodiment, the beam operating mode supported by the network node includes a preset default beam operating mode. When the first instruction information indicates the default beam operating mode or is empty, the network node determines and applies the default beam operating mode, or if the network node determines to apply only the default beam operating mode, it may transmit only the default beam operating mode to the base station. By applying the default beam operating mode, the network node can make the division of labor of each operating unit in the network node clearer, reduce the configuration amount input by the base station to the network node, and save network configuration resources.

[0085] In one embodiment, the initial operating mode of the network node may be set to a preset default beam operating mode to facilitate the control of the operating state of the network node by making its initial operating mode in a state where the parameters are determined.

[0086] In one embodiment, the beam operating mode supported by the network node may include at least one of the following types, but is not limited thereto, and includes several operating parameters. The duration of the operating mode, The switching time point of the operating mode, The area of the operating surface guiding the electromagnetic wave signal, Material parameters or materials for guiding electromagnetic wave signals Shape of the working surface for guiding electromagnetic wave signals Orientation of the working surface for guiding electromagnetic wave signals Angle formed by the normal of the working surface for guiding electromagnetic wave signals and the beam for guiding electromagnetic wave signals Number of cells of the working surface for guiding electromagnetic wave signals

[0087] Here, the duration of the operating mode may be the length or range of the duration of the operating mode. For example, it may be presented as the start time and end time of the operating mode, or the length or range of the beam forming time, for example, the start time and end time of the beam forming.

[0088] The switching point of the operating mode is, for example, the start point of the operating mode, the end point of the operating mode, or the start point of beam forming, the end point of beam forming.

[0089] The area of the working surface for guiding electromagnetic wave signals may be, for example, the area of the working surface for receiving electromagnetic wave signals from a base station, the area of the working surface for receiving electromagnetic wave signals from a terminal, or the ratio of the area of the working surface for receiving electromagnetic wave signals from a base station to the area of the working surface for receiving electromagnetic wave signals from a terminal.

[0090] In the material parameters or materials for guiding electromagnetic wave signals, for example, the material parameters may be the electromagnetic wave absorption coefficient, the electromagnetic wave loss coefficient, the conductivity, the electromagnetic wave guiding coefficient, and the material may be a superconducting material, a low superconducting material, a high superconducting material, or a medium superconducting material.

[0091] The shape of the working surface for guiding electromagnetic wave signals may be, for example, rectangular, circular, parabolic, concave, flat, or transmissive.

[0092] The orientation of the working surface of the electromagnetic wave signal may be, for example, upward, downward, or towards the base station.

[0093] The angle formed by the normal of the operating surface guiding the electromagnetic wave signal and the beam guiding the electromagnetic wave signal may be, for example, an acute angle, a right angle, or an obtuse angle.

[0094] The number of cells of the operating surface guiding the electromagnetic wave signal may be, for example, 1, 2, or 4.

[0095] Since different beam operation modes correspond to respective operation parameters, the related beam operation modes may be further determined by their respective operation parameters. Therefore, the first instruction information transmitted by the base station may be explicit, directly instructing the corresponding beam operation mode by the first instruction information, or implicit, indirectly instructing the corresponding beam operation mode by directly instructing the operation parameters.

[0096] Furthermore, before step S100, it further includes step S800, but is not limited thereto.

[0097] Step S800: The base station transmits the first service information to the base station so as to generate first beam identification information based on the first service information representing the correspondence between each beam in the network node and the alignment position of each beam, and the alignment position of the acquired target beam of the network node for one terminal.

[0098] In one embodiment, by transmitting the first service information to the base station, the base station can generate the first beam identification information based on the first service information, and the base station can easily and accurately determine the first beam identification information based on the first service information, which is advantageous for reducing the difficulty of the base station's flow execution.

[0099] In one embodiment, the first beam identification information includes first hint information representing the alignment position of the target beam of the network node for one terminal. When the network node acquires the first hint information, since the first service information is stored in the network node, based on the first hint information and the first service information, the first beam for aligning with the terminal corresponding to the alignment position of the target beam can be formed in the first time domain. Therefore, in actual application, the base station can directly transmit the alignment position of the target beam to the network node without transmitting the information related to the determined first beam, that is, the network node can indirectly determine the first beam from the alignment position of the target beam.

[0100] Furthermore, before step S100, it further includes step S900, but is not limited thereto.

[0101] Step S900: The base station transmits the second service information to the base station so that the base station generates the first beam identification information based on the second service information representing the correspondence between each template beam in the network node and the test value of each template beam, and the acquired first beam test parameters.

[0102] In one embodiment, by transmitting the second service information to the base station, the base station generates the first beam identification information based on the second service information, that is, the base station can easily and accurately determine the first beam identification information based on the second service information, which is advantageous for reducing the difficulty of the base station's flow execution.

[0103] In one embodiment, the first beam identification information includes second hint information including first beam test parameters for a template beam. When the network node obtains the second hint information, since the second service information is stored in the network node, based on the first beam test parameters and the second service information, the first beam corresponding to the first beam test parameters, that is, the template beam corresponding to the first beam test parameters can be formed in the first time domain. Therefore, in actual application, the base station can directly send the corresponding beam test parameters for the template beam to the network node without transmitting the information regarding the determined first beam, that is, the network node can indirectly determine the first beam from the corresponding beam test parameters for the template beam.

[0104] As shown in FIG. 11, FIG. 11 is a flowchart of a beam processing method according to another embodiment of the present application. This beam processing method can be applied to the base station in the embodiment shown in FIG. 1 and includes, but is not limited to, step S1000.

[0105] Step S1000: The network node determines the first time domain from the beam formation time information in the beam time domain information, and transmits the first beam identification information and the beam time domain information to the network node so that the first beam for guiding the signal is formed in the first time domain.

[0106] Here, the beam formation time information is used to represent the time when the network node forms a beam to guide a signal, and the first beam is determined by the network node from the first beam identification information.

[0107] In one embodiment, based on the first beam identification information transmitted by the base station, the network node can determine a first beam for guiding a signal based on the first beam identification information. Under the condition that the first beam is formed in the first time domain, the electromagnetic wave signal transmitted or received by the base station can be guided by the first beam. That is, the guidance for the electromagnetic wave signal can improve the reception amount of the electromagnetic wave signal by the base station, thereby improving the quality of the wireless communication and the wireless communication efficiency. Further, since the first time domain is determined from the beam formation time information indicating the time for the network node to form a beam for guiding a signal, the network node can guide the signal at the corresponding time by forming the corresponding beam in the first time domain, avoiding the occurrence of incorrect guidance or signaling storms, which is advantageous for improving the wireless communication efficiency.

[0108] It should be noted that the step S1000 in this embodiment has the same technical principle and technical effect as the steps S100 - S300 in the embodiment shown in FIG. 2 above, but the difference lies in that the execution entities of the two embodiments are different. In the embodiment shown in FIG. 2 above, the execution entity is the network node, while in this embodiment, the execution entity is the base station. For the technical principle and technical effect of this embodiment, reference may be made to the above description in the embodiment shown in FIG. 2. To avoid duplication and redundancy, it will not be mentioned here.

[0109] When the base station matches with the terminal, the base station can obtain information about the terminal such as location information and communication capability information. Therefore, the base station can evaluate the channel transmission capability between the base station and the terminal and determine the corresponding beam time domain information. Similarly, the base station can also obtain the related information of the network node and obtain the first beam identification information based on the related information. Since the related information corresponding to the network node is diverse, the method for the base station to obtain the first beam identification information is not limited.

[0110] In one embodiment, the beam time domain information transmitted by the base station further includes beamforming slot information representing the period of beamforming. By transmitting the beamforming slot information to the network node, the network node periodically forms a first beam and a second beam in the first time domain based on the beamforming slot information. That is, the network node forms the corresponding beam on the bias slot within each period. In this case, the network node may allocate the remaining time within each period to forming other beams that require alignment with other terminals or other services, which is advantageous for improving the operating efficiency of the network node.

[0111] It should be noted that the steps of this embodiment have the same technical principles and technical effects as step S340 of the embodiment shown in FIG. 8 above, but the difference lies in that the execution entities of the two embodiments are different. In the embodiment shown in FIG. 8 above, the execution entity is the network node, while in this embodiment, the execution entity is the base station. For the technical principles and technical effects of this embodiment, reference may be made to the above description in the embodiment shown in FIG. 8. To avoid duplication and redundancy, it will not be mentioned here.

[0112] In one embodiment, the base station may transmit beamforming trigger information including a first time interval to the network node so that the network node can form a first beam and a second beam in the first time domain according to the first time interval, thereby meeting the time domain requirements for forming the corresponding beam in the current scenario.

[0113] Note that the steps of this embodiment have the same technical principle and technical effect as steps S350 and S360 of the embodiment shown in FIG. 9 above, but the difference lies in that the execution entities of the two embodiments are different. In the embodiment shown in FIG. 9 above, the execution entity is a network node, while in this embodiment, the execution entity is a base station. For the technical principle and technical effect of this embodiment, reference may be made to the above description in the embodiment shown in FIG. 9, and in order to avoid duplication and redundancy of content, it will not be mentioned here.

[0114] In one embodiment, the beamforming time information is N1 (where N1 is any integer between 1 and 14) consecutive orthogonal frequency division multiplexing (OFDM) symbols, and one OFDM symbol, and N2 (where N2 is 2, 4, or 7) consecutive OFDM symbols, and two consecutive OFDM symbols, and another two consecutive OFDM symbols, and one OFDM symbol, and another OFDM symbol that is four OFDM symbols away from one OFDM symbol, and two first beam symbols respectively distributed on two consecutive slots, where the positions of the two first beam symbols on their respective slots correspond, and the first beam symbol includes one OFDM symbol and another OFDM symbol that is four OFDM symbols away from one OFDM symbol, two first beam symbols, and includes beamforming symbols including at least one of the types of

[0115] Note that the beamforming symbol in this embodiment has the same technical principle and technical effect as the beamforming symbol in the above related embodiment, but the difference lies in that the execution entities of the two embodiments are different. In the above related embodiment, the execution entity is a network node, while in this embodiment, the execution entity is a base station. For the technical principle and technical effect of this embodiment, reference may be made to the above related description in the above related embodiment. To avoid duplication and redundancy of content, it will not be mentioned here.

[0116] Furthermore, the beam processing method further includes, but is not limited to, step S1100.

[0117] Step S1100: The network node transmits beam indication information to the network node so as to form a first beam for aligning with the first terminal in a first time domain based on the first beam identification information and the beam indication information for instructing the first beam to be aligned with the first terminal.

[0118] It is understood that step S1100 of this embodiment has the same technical principle and technical effect as steps S320 and S330 of the embodiment shown in FIG. 4 above, but the difference lies in that the execution entities of the two embodiments are different. In the embodiment shown in FIG. 4 above, the execution entity is a network node, while in this embodiment, the execution entity is a base station. For the technical principle and technical effect of this embodiment, reference may be made to the above description in the embodiment shown in FIG. 4. To avoid duplication and redundancy of content, it will not be mentioned here.

[0119] Furthermore, the beam processing method further includes, but is not limited to, step S1200.

[0120] Step S1200: The network node determines a second beam for aligning with the base station from the second beam identification information, and transmits the second beam identification information to the network node so as to form the second beam in the first time domain.

[0121] In one embodiment, since the relative positions between the network node and the base station are not fixed, the network node cannot determine the position of the base station. Therefore, it is impossible to align with the base station based on a fixed beam. Under this condition, similar to obtaining the first beam identification information, the second beam is determined by the second beam identification information transmitted by the base station, and the network node can align with the base station based on the second beam to realize signal guidance.

[0122] In the example of FIG. 12, the beam processing method further includes, but is not limited to, steps S1300 to S1400.

[0123] Step S1300: Obtain the beam operation mode supported by the network node and transmitted by the network node.

[0124] Step S1400: Transmit the first instruction information to the network node according to the beam operation mode, so that the network node determines and applies the first beam operation mode from the first instruction information and the beam operation mode supported by the network node.

[0125] It should be noted that the technical principles and technical effects of steps S1300 to S1400 in this embodiment are the same as those of steps S500 to S700 in the embodiment shown in FIG. 10 above, but the difference lies in that the execution entities of the two embodiments are different. In the embodiment shown in FIG. 10 above, the execution entity is the network node, while in this embodiment, the execution entity is the base station. For the technical principles and technical effects of this embodiment, reference may be made to the above description in the embodiment shown in FIG. 10. To avoid duplication and redundancy of content, it will not be mentioned here.

[0126] Furthermore, in the example of FIG. 13, before "transmitting the first beam identification information to the network node" in step S1000, it further includes, but is not limited to, steps S1500 to S1800.

[0127] Step S1500: Obtain first service information representing the correspondence between the position information of the network node, the position information of the terminal, and each beam in the network node and the alignment position of each beam transmitted by the network node.

[0128] Step S1600: Determine the alignment position of the target beam of the network node with respect to the terminal from the position information of the network node and the position information of the terminal.

[0129] Step S1700: Determine the target beam corresponding to the alignment position of the target beam from the alignment position of the target beam and the first service information.

[0130] Step S1800: Generate first beam identification information based on the target beam.

[0131] In one embodiment, the base station can determine the target beam based on the position information of the network node, the position information of the terminal, and the first service information transmitted by the network node, and further generate the first beam identification information based on the target beam. Since the first beam identification information does not need to be determined from the position information of the base station itself, in actual application, the base station can easily and accurately determine the first beam identification information, thereby reducing the difficulty of the base station's flow execution.

[0132] Note that the first service information may be pre-stored in the network node so that the base station can directly obtain the first service information from the network node. The method for the base station to obtain the position information of the network node and the position information of the terminal is not limited. For example, it may be measured and determined by a method of transmitting a positioning reference signal.

[0133] Since the alignment positions of different beams respectively correspond to the corresponding beams, the associated beam operation mode can be further determined by the alignment position of the corresponding beam. Therefore, the first beam identification information transmitted by the base station may be explicit information that directly indicates the corresponding beam by the first beam identification information, or may be implicit information that indirectly indicates the corresponding beam by directly indicating the alignment position of the corresponding beam by the first beam identification information.

[0134] In one embodiment, at least one set of template beams is included in the network node, the test value of the terminal for each set of template beams corresponds to its observation position, and different test values are embodied corresponding to different observation positions. This correspondence relationship is stored in the network node in the form of second service information. That is, the test value of each set of fixed beams has a correspondence relationship with the beam of the network node aligned with the observation position. In this case, when the base station obtains the test value of the terminal for the template beam, it can determine the corresponding template beam from the obtained second service information, and further determine the first beam identification information from the corresponding template beam.

[0135] It should be noted that in this embodiment, the technical principles and technical effects are the same as those of steps S800 and S900 in the above embodiment, but the difference lies in that the execution entities of these embodiments are different. In the embodiments shown in steps S800 and S900 above, the execution entity is the network node, while in this embodiment, the execution entity is the base station. For the technical principles and technical effects of this embodiment, reference may be made to the descriptions in the embodiments shown in steps S800 and S900 above. To avoid duplication and redundancy of content, it will not be mentioned here.

Further, since the first time domain is determined from the beam formation time information representing the time for the network node to form a beam to guide a signal, the network node can guide the signal at the corresponding time by forming the corresponding beam in the first time domain, which can avoid incorrect guidance and the occurrence of signaling storms, and is advantageous for improving the wireless communication efficiency.
