Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0002] In a communication system, a terminal device may access a network device according to a synchronization system / physical broadcast channel block (SS / PBCH block, also referred to as SSB) beam fixedly configured by the network device.

[0003] However, during the communication process of the terminal device, when the terminal device moves at a fast speed, the fast moving speed will cause the position to change quickly, and the beam may be switched frequently, which will cause the signal of the terminal device to fluctuate greatly and become unstable, thereby reducing the communication quality.

[0004] Therefore, how to better connect terminal devices to network devices and improve the communication quality between terminal devices and network devices has become an urgent problem to be solved. Summary of the invention

[0005] The present application provides a communication method and apparatus, which can enable a terminal device to better access a network device and improve the communication quality between the terminal device and the network device.

[0006] In a first aspect, a communication method is provided, which can be executed by a first network device, or by a component of the first network device, such as a processor, a chip, or a chip system of the first network device, or by a logic module or software that can realize all or part of the functions of the first network device. The method includes: when the first network device meets a first preset condition, adjusting the beam from the first beam to the second beam; after adjusting the beam to the second beam, when the second preset condition is met, adjusting the beam from the second beam to the first beam. The first preset condition is that within the coverage of the first network device, the number of terminal devices with a moving speed greater than or equal to the first preset threshold is greater than or equal to the second preset threshold; the beam type of the first beam is a narrow beam, and the beam type of the second beam is a wide beam; the second preset condition is that within the coverage of the first network device, the number of terminal devices with a moving speed greater than or equal to the first preset threshold is less than the second preset threshold.

[0007] Based on the first aspect, when the first preset condition is met, the first network device adjusts the beam from a narrow beam (i.e., the first beam) to a wide beam (i.e., the second beam), so that when a terminal device with a mobile speed greater than or equal to the first preset threshold accesses the first network device, the beam no longer needs to be switched frequently, thereby reducing the signal fluctuation of the terminal device, improving the reliability of the terminal device accessing the first network device, and improving the communication quality between the terminal device and the first network device; when the second preset condition is met, the number of terminal devices with a mobile speed greater than or equal to the first preset threshold within the coverage range of the first network device is small, and the beam of the first network device can be adjusted from a wide beam (i.e., the second beam) to a narrow beam (i.e., the first beam), which can increase the coverage range of the first network device, improve the reference signal receiving power (RSRP) within the coverage range of the first network device, and increase the number of terminal devices accessing the first network device.

[0008] In a possible implementation, when the first network device meets the first preset condition, the first indication information is sent to the second network device; wherein the first indication information is used to instruct the second network device to adjust the beam to a wide beam.

[0009] Based on this possible implementation, when the first preset condition is met, the first network device sends a first indication message to the second network device, which can enable the second network device to adjust the beam to a wide beam in advance, thereby avoiding as much as possible the situation where the second network device fails to adjust the beam to a wide beam in time due to delay, resulting in a decrease in communication quality. Terminal devices within the coverage area of ​​the second network device and with a moving speed greater than or equal to the first preset threshold no longer frequently switch beams, thereby reducing signal fluctuations of the terminal device, and improving the communication performance of the terminal device and the second network device.

[0010] In one possible implementation, the first network device sends second indication information to the second network device; wherein the second indication information is used to instruct the second network device to adjust the beam to a narrow beam when a third preset condition is met, and the third preset condition is that within the coverage range of the second network device, the number of terminal devices with a moving speed greater than or equal to the first preset threshold is less than the second preset threshold.

[0011] Based on this possible implementation, the first network device can instruct the second network device to adjust the wide beam to a narrow beam when the third preset condition is met, so as to increase the coverage of the second network device, improve the RSRP within the coverage of the second network device, and increase the number of terminal devices accessing the second network device.

[0012] In a possible implementation, the first network device determines the average modulation and coding scheme (MCS) order corresponding to one or more terminal devices that meet the fourth preset condition within a preset time; if the average MCS order is greater than a third preset threshold, the first configuration information is sent to the one or more terminal devices that meet the fourth preset condition; or, if the average MCS order is less than or equal to the third preset threshold, the second configuration information is sent to the one or more terminal devices that meet the fourth preset condition. The fourth preset condition is that the moving speed within the coverage area of ​​the first network device is greater than or equal to the first preset threshold; the first configuration information is used to indicate a cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) waveform; the second configuration information is used to indicate a discrete Fourier transform-spread OFDM (DFT-S-OFDM) waveform.

[0013] Based on this possible implementation, the first network device can determine the average MCS order of the terminal devices whose moving speed is greater than or equal to the first preset threshold within the coverage area of ​​the first network device within a preset time; when the average MCS order is greater than the third preset threshold, the first configuration information can be used to instruct the terminal device to use the CP-OFDM waveform for data transmission, which can reduce the transmission power of the terminal device and reduce power consumption; when the MCS order is less than or equal to the third preset threshold, the second configuration information can be used to instruct the terminal device to use the DFT-S-OFDM waveform for data transmission, which can increase the transmission power of the terminal device, avoid distortion, and improve communication performance. At the same time, sending the first configuration information or the second configuration information to the terminal device to fix the configuration waveform can avoid frequent reconfiguration of the waveform for the terminal device as much as possible, thereby reducing the risk of dropped calls of the terminal device, enabling the terminal device to obtain optimal performance, and improving the communication quality between the terminal device and the first network device.

[0014] In a possible implementation, the first network device determines the moving speed of the terminal device within the coverage of the first network device according to one or more of the following parameters: Doppler frequency shift, or global positioning system speed (GPS speed).

[0015] Based on this possible implementation, the first network device may determine the moving speed of the terminal device according to parameters such as the Doppler frequency shift of the signal sent by the terminal device to the first network device, or GPS speed.

[0016] In a second aspect, a communication method is provided, which can be executed by a second network device, or by a component of the second network device, such as a processor, a chip, or a chip system of the second network device, or by a logic module or software that can implement all or part of the functions of the second network device. The method includes: the second network device receives first indication information from the first network device; according to the first indication information, adjusts the beam from the third beam to the fourth beam. The first indication information is used for the second network device to adjust the beam to a wide beam; the beam type of the third beam is a narrow beam, and the beam type of the fourth beam is a wide beam.

[0017] Based on the second aspect, the second network device receives the first indication information from the first network device, and can adjust the beam from a narrow beam (i.e., the third beam) to a wide beam (i.e., the fourth beam) in advance. When the terminal device enters the coverage of the second network device, it can access the second network device through the wide beam of the second network device, thereby avoiding as much as possible the situation where the terminal device drops calls due to the delay in not adjusting to the wide beam in time; at the same time, the second network device adjusts the beam from a narrow beam (the third beam) to a wide beam (the fourth beam), so that the terminal device with a moving speed greater than or equal to the first preset threshold no longer frequently switches the beam, thereby reducing the signal fluctuation of the terminal device, improving the reliability of the terminal device accessing the second network device, and improving the communication quality between the terminal device and the second network device.

[0018] In a possible implementation, the second network device receives second indication information from the first network device; and adjusts the beam from the fourth beam to the third beam according to the second indication information. The second indication information is used to instruct the second network device to adjust the beam to a narrow beam when a third preset condition is met, and the third preset condition is that within the coverage of the second network device, the number of terminal devices with a moving speed greater than or equal to a first preset threshold is less than a second preset threshold.

[0019] Based on this possible implementation, the second network device can adjust the beam from a wide beam (i.e., the fourth beam) to a narrow beam (i.e., the third beam) according to the second indication information, which can increase the coverage of the second network device, improve the RSRP within the coverage of the second network device, and increase the number of terminal devices accessing the second network device.

[0020] In a possible implementation, when the second network device meets the third preset condition, the beam is adjusted from the fourth beam to the third beam.

[0021] Based on this possible implementation, when the third preset condition is met, the second network device can adjust the beam from a wide beam (i.e., the fourth beam) to a narrow beam (i.e., the third beam), which can increase the coverage of the second network device, improve the RSRP within the coverage of the second network device, and increase the number of terminal devices accessing the second network device; compared to the second network device adjusting the beam according to the second indication information from the first network device, the second network device can adjust the beam according to the third preset condition, which can reduce transmission overhead, avoid as much as possible the situation where the beam is always a wide beam due to the second network device not receiving the second indication information, and improve the reliability of communication.

[0022] In one possible implementation, when the second network device meets the fifth preset condition, the beam is adjusted from the third beam to the fourth beam; wherein the fifth preset condition is that within the coverage range of the second network device, the number of terminal devices whose moving speed is greater than or equal to the first preset threshold is greater than or equal to the second preset threshold.

[0023] Based on this possible implementation, when the fifth preset condition is met, the second network device adjusts the beam from a narrow beam (i.e., the third beam) to a wide beam (i.e., the fourth beam), so that the terminal device with a moving speed greater than or equal to the first preset threshold no longer frequently switches the beam, thereby reducing the signal fluctuation of the terminal device, improving the reliability of the terminal device accessing the second network device, and improving the communication quality between the terminal device and the second network device; compared to adjusting the beam according to the first indication information, the second network device adjusts the beam according to the fifth preset condition to reduce transmission overhead, avoid as much as possible the situation where the beam is always a narrow beam due to the second network device not receiving the first indication information, and improve the reliability of communication.

[0024] In a possible implementation, the first network device determines the moving speed of the terminal device within the coverage area of ​​the first network device according to one or more of the following parameters: Doppler frequency shift, or GPS speed.

[0025] Based on this possible implementation, the second network device may determine the moving speed of the terminal device according to parameters such as the Doppler frequency shift of the signal sent by the terminal device to the first network device, or GPS speed.

[0062] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the related technologies of the present application is first given as follows.

[0063] 1) High speed dedicated network (HSDN) and high speed public network

[0064] Among them, HSDN can be called a private network. HSDN is deployed around the high-speed rail line and can be a cell that provides services for high-speed rail users (also called terminal devices with higher mobile speeds). This cell can be called a high-speed cell.

[0065] Among them, the high-speed rail public network can be called a public network, which is deployed around the HSDN and can be a community that provides services to non-high-speed rail users.

[0066] It is understandable that there is no strict division between users of HSDN and high-speed rail public network services. High-speed rail users can have priority access to HSDN based on network planning, or they can access the high-speed rail public network; similarly, non-high-speed rail users can have priority access to the high-speed rail public network based on network planning, or they can access HSDN.

[0067] 2) Downlink coverage

[0068] Among them, downlink coverage is one of the important indicators of communication quality, which can be the range covered by the beam of network equipment.

[0069] Optionally, a terminal device within the coverage area of ​​the network device can access the network device through the beam of the network device.

[0070] 3) Beam

[0071] The type of beam may be a wide beam, a narrow beam, or other types of beams without limitation.

[0072] In the protocol, the term "beam" is not used directly to represent the beam. Instead, other methods are used to implicitly describe beam-related operations. Beams generally correspond to resources, that is, resources can also be used to indicate or describe beams.

[0073] 4) Uplink coverage

[0074] Among them, due to the large penetration loss of high-speed rail and the limited transmission power of terminal equipment, the uplink coverage is subject to certain restrictions.

[0075] Optionally, the terminal device may choose to use a high-order MCS or a low-order MCS according to communication quality and communication requirements.

[0076] Optionally, the terminal device may perform data transmission according to a CP-OFDM waveform or a DFT-S-OFDM waveform.

[0077] Among them, the CP-OFDM waveform has better performance when the MCS is high. The CP-OFDM waveform can transmit data through discontinuous time-frequency domain resources, but the peak to average power ratio (PAPR, also referred to as peak-to-average power ratio) is high.

[0078] Among them, the DFT-S-OFDM waveform has better performance when the MCS is low, and the PAPR is higher, which can improve the communication quality, but it needs to be sent with higher transmission power.

[0079] Exemplarily, the network device may instruct the terminal device to adopt a relevant waveform based on the channel quality of the uplink of the terminal device.

[0080] For example, when the uplink channel quality is good, the MCS of the terminal device is low, and the network device can instruct the terminal device to use the CP-OFDM waveform; when the uplink channel quality is poor, the MCS of the terminal device is high, and the network device can instruct the terminal device to use the DFT-S-OFDM waveform.

[0081] It can be understood that the network device can instruct the terminal device to switch the waveform according to the channel quality of the uplink, and the terminal device can transmit data according to the switched waveform, which can improve the communication performance of the terminal device.

[0082] However, since the signal fluctuations of terminal devices with faster moving speeds are larger and the signal changes faster, the network equipment's judgment on the uplink channel quality is not accurate and cannot better instruct the terminal devices to switch waveforms.

[0083] For example, the network device instructs the terminal device to use the DFT-S-OFDM waveform at time 1, and at time 2, the uplink channel quality is better, and the terminal device is more suitable to use the CP-OFDM waveform. The network device can instruct the terminal device to use the CP-OFDM waveform by reconfiguration. However, when there are many terminal devices, the network device needs to reconfigure all terminal devices, which may cause a large overhead, and reconfiguring all terminal devices may increase the probability of dropped calls of some terminal devices, reducing the communication quality between the terminal devices and the network device.

[0084] Based on the description of the above content, the terminal device can access the network device according to the SSB narrow beam or SSB wide beam fixedly configured by the network device, and the terminal device can also transmit data according to the waveform indicated by the network device.

[0085] Among them, the following Figure 1As shown, the SSB narrow beam of the network device has a wide coverage range and a high reference signal receiving power (RSRP). However, when the terminal device moves at a high speed, the SSB narrow beam may not be able to keep up with the position change of the terminal device. Frequent beam switching of the terminal device may cause large signal fluctuations of the terminal device, thereby reducing the reliability of communication.

[0086] Among them, the following Figure 2 As shown, SSB wide beam can improve the reliability of terminal devices accessing network devices, and RSRP is lower, but the cell coverage will decrease and the number of terminal devices accessing the network devices will decrease.

[0087] For example, when a terminal device enters a cell where the network device uses a fixed SSB narrow beam, it can access the network device according to the SSB narrow beam. When the terminal device moves at a fast speed, the fast moving speed will cause the position to change quickly, and the beam may be switched frequently, which will cause the signal of the terminal device to fluctuate greatly and become unstable, thereby reducing the communication quality.

[0088] In summary, how to enable terminal devices to better access network devices and improve the communication performance between terminal devices and network devices has become an urgent problem to be solved.

[0089] In order to solve the above technical problems, the present application provides a communication method, which includes: when the first network device meets the first preset condition, adjusting the beam from the first beam to the second beam; after adjusting the beam to the second beam, when the second preset condition is met, adjusting the beam from the second beam to the first beam. The first preset condition is that within the coverage of the first network device, the number of terminal devices with a moving speed greater than or equal to the first preset threshold is greater than or equal to the second preset threshold; the beam type of the first beam is a narrow beam, and the beam type of the second beam is a wide beam; the second preset condition is that within the coverage of the first network device, the number of terminal devices with a moving speed greater than or equal to the first preset threshold is less than the second preset threshold.

[0090] In an embodiment of the present application, when the first preset condition is met, the first network device adjusts the beam from a narrow beam (i.e., the first beam) to a wide beam (i.e., the second beam), so that a terminal device with a moving speed greater than or equal to the first preset threshold no longer needs to frequently switch beams when accessing the first network device, thereby reducing signal fluctuations of the terminal device, improving the reliability of the terminal device accessing the first network device, and improving the communication quality between the terminal device and the first network device; when the second preset condition is met, the number of terminal devices with a moving speed greater than or equal to the first preset threshold within the coverage range of the first network device is small, and the beam of the first network device can be adjusted from a wide beam (i.e., the second beam) to a narrow beam (i.e., the first beam), which can increase the coverage range of the first network device, improve the RSRP within the coverage range of the first network device, and increase the number of terminal devices accessing the first network device.

[0117] The communication method provided by the embodiment of the present application will be described below in conjunction with the accompanying drawings. It is understandable that in the embodiment of the present application, the terminal device or the network device can perform some or all of the steps in the embodiment of the present application, and these steps or operations are only examples, and the embodiment of the present application can also perform other operations or various operations. In addition, each step can be performed in the different order presented in the embodiment of the present application, and it is possible not to perform all the operations in the embodiment of the present application.

[0118] as follows Figure 5 The above is an interactive schematic diagram of a communication method provided by this application. Figure 5 , the communication method comprises the following steps:

[0119] S501: When a first preset condition is met, the first network device adjusts the beam from a first beam to a second beam.

[0120] Among them, the first preset condition is that within the coverage range of the first network device, the number of terminal devices (which can be called high-speed terminal devices or high-speed users) with a mobile speed greater than or equal to the first preset threshold is greater than or equal to the second preset threshold; the beam type of the first beam is a narrow beam, and the beam type of the second beam is a wide beam.

[0121] Optionally, the first network device may initially configure the beam as the first beam. Since within the coverage area of ​​the first network device, terminal devices (which may be referred to as low-speed terminal devices or low-speed users) whose mobile speed is less than a first preset threshold value may not switch beams frequently, terminal devices whose mobile speed is less than the first preset threshold value may access the first network device according to the first beam.

[0122] Optionally, the first preset threshold and the second preset threshold may be determined according to an actual communication scenario or actual communication requirement. This application provides several possible examples:

[0123] As an exemplary example, taking the first preset threshold value as 100 kilometers per hour (km / h) and the second preset threshold value as 10, when the moving speed of the terminal device is greater than or equal to 100 km / h, and the number of terminal devices with a moving speed greater than or equal to 100 km / h is greater than or equal to 10, the first network device adjusts the beam from the first beam to the second beam.

[0124] Another exemplary example, taking the first preset threshold value as 150km / h, when the moving speed of the terminal device is greater than or equal to 150km / h, and the number of terminal devices with a moving speed greater than or equal to 150km / h is greater than or equal to the second preset threshold value, the first network device adjusts the beam from the first beam to the second beam.

[0125] To summarize, when the first preset condition is met, the first network device adjusts the beam from the first beam to the second beam, so that the terminal device with a moving speed greater than or equal to the first preset threshold no longer switches beams frequently, and the signal fluctuation of the terminal device with a moving speed greater than or equal to the first preset threshold is reduced. The terminal device with a moving speed greater than or equal to the first preset threshold can be given priority to access the first network device, and the reliability of the terminal device with a moving speed greater than or equal to the first preset threshold accessing the first network device is improved, and the communication quality between the terminal device with a moving speed greater than or equal to the first preset threshold and the first network device is improved.

[0126] Optionally, the first network device may determine the moving speed of the terminal device within the coverage of the first network device according to one or more of the following parameters: Doppler frequency shift, or GPS speed. This application proposes several possible embodiments:

[0127] In a first possible embodiment, the terminal device may send a signal to the first network device, and the first network device determines the moving speed of the terminal device according to the Doppler frequency shift of the received signal.

[0128] In a second possible embodiment, the terminal device may determine its own GPS speed, and then send the GPS speed to the first network device. The first network device may determine the moving speed of the terminal device according to the GPS speed.

[0129] S502: After the first network device adjusts the beam to the second beam, when a second preset condition is met, the first network device adjusts the beam from the second beam to the first beam.

[0130] Among them, the second preset condition is that within the coverage area of ​​the first network device, the number of terminal devices whose moving speed is greater than or equal to the first preset threshold is less than the second preset threshold.

[0131] It can be understood that when the second preset condition is met, the number of terminal devices with a moving speed greater than or equal to the first preset threshold within the coverage range of the first network device is small, the beam of the first network device can be adjusted from the second beam to the first beam, the RSRP within the coverage range of the first network device can be improved, and the number of terminal devices accessing the first network device can be increased; at the same time, terminal devices with a moving speed less than the first preset threshold can access the first network device without frequently switching waveforms, and can access the first network device according to the second beam.

[0132] Therefore, the above Figure 5 The communication method can take into account terminal devices whose mobile speed is greater than or equal to a first preset threshold and terminal devices whose mobile speed is less than the first preset threshold, and can give priority to terminal devices whose mobile speed is greater than or equal to the first preset threshold to access the first network device, thereby improving the user experience of terminal devices whose mobile speed is greater than or equal to the first preset threshold.

[0133] Based on the above Figure 5 The communication method shown, when the first preset condition is met, the first network device adjusts the beam from a narrow beam (i.e., the first beam) to a wide beam (i.e., the second beam), so that the terminal device with a moving speed greater than or equal to the first preset threshold no longer frequently switches the beam, the signal fluctuation of the terminal device with a moving speed greater than or equal to the first preset threshold is reduced, the reliability of the terminal device with a moving speed greater than or equal to the first preset threshold accessing the first network device is improved, and the communication quality between the terminal device with a moving speed greater than or equal to the first preset threshold and the first network device is improved; when the second preset condition is met, the number of terminal devices with a moving speed greater than or equal to the first preset threshold within the coverage area of ​​the first network device is small, the beam of the first network device can be adjusted from a narrow beam (second beam) to a wide beam (first beam), the coverage area of ​​the first network device can be increased, the RSRP within the coverage area of ​​the first network device is improved, and the number of terminal devices accessing the first network device is increased.

[0134] Based on the above Figure 5 In the described embodiment, in the embodiment of the present application, the second network device can also adjust the beam, and the method includes: when the first preset condition is met, the first network device sends a first indication information to the second network device; accordingly, the second network device receives the first indication information from the first network device, and adjusts the beam from the third beam to the fourth beam according to the first indication information.

[0135] The first indication information is used to instruct the second network device to adjust the beam to a wide beam.

[0136] Among them, the beam type of the third beam is a narrow beam, and the beam type of the fourth beam is a wide beam.

[0137] Optionally, the second network device may be a network device in a neighboring area of ​​the first network device. The second network device may initially configure the beam as a third beam. Since within the coverage area of ​​the second network device, terminal devices with a moving speed less than a first preset threshold may not switch beams frequently, terminal devices with a moving speed less than the first preset threshold may access the second network device based on the third beam.

[0138] It can be understood that the first network device sends the first indication information to the second network device, so that the second network device can adjust the beam to a wide beam in advance, and avoid as much as possible the situation where the second network device fails to adjust the beam to a wide beam in time due to delay, resulting in a decrease in communication quality. It can make the terminal devices with a moving speed greater than or equal to the first preset threshold within the coverage area of ​​the second network device no longer switch beams frequently, and reduce the signal fluctuation of the terminal devices with a moving speed greater than or equal to the first preset threshold, and can improve the communication performance between the terminal devices with a moving speed greater than or equal to the first preset threshold and the second network device.

[0139] Correspondingly, the second network device may also be the same as the first network device. When the fifth preset condition is met, the second network device adjusts the beam from the third beam to the fourth beam.

[0140] Among them, the fifth preset condition is that within the coverage area of ​​the second network device, the number of terminal devices whose moving speed is greater than or equal to the first preset threshold is greater than or equal to the second preset threshold.

[0141] It can be understood that when the fifth preset condition is met, the second network device adjusts the beam from a narrow beam (i.e., the third beam) to a wide beam (i.e., the fourth beam), so that the terminal device with a moving speed greater than or equal to the first preset threshold no longer switches the beam frequently, and the signal fluctuation of the terminal device with a moving speed greater than or equal to the first preset threshold is reduced, thereby improving the reliability of the terminal device with a moving speed greater than or equal to the first preset threshold accessing the second network device, and improving the communication quality between the terminal device with a moving speed greater than or equal to the first preset threshold and the second network device; compared with adjusting the beam according to the first indication information, the second network device adjusts the beam according to the fifth preset condition to reduce transmission overhead, and avoids as much as possible the situation where the beam is always a narrow beam due to the second network device not receiving the first indication information, thereby improving the reliability of communication.

[0142] Optionally, the first network device sends second indication information to the second network device; correspondingly, the second network device receives the second indication information from the first network device, and adjusts the beam from the fourth beam to the third beam according to the second indication information.

[0143] Among them, the second indication information is used to instruct the second network device to adjust the beam to a narrow beam when a third preset condition is met, and the third preset condition is that within the coverage range of the second network device, the number of terminal devices with a moving speed greater than or equal to the first preset threshold is less than the second preset threshold.

[0144] It can be understood that the first network device can instruct the second network device to adjust the wide beam to a narrow beam when the third preset condition is met, so as to increase the coverage of the second network device, improve the RSRP within the coverage of the second network device, and increase the number of terminal devices accessing the second network device.

[0145] Correspondingly, the second network device may also adjust the beam from the fourth beam to the third beam when the third preset condition is met, just like the first network device.

[0146] It can be understood that when the third preset condition is met, the second network device can adjust the beam from the fourth beam to the third beam, which can increase the coverage of the second network device, improve the RSRP within the coverage of the second network device, and increase the number of terminal devices accessing the second network device; compared with the second network device adjusting the beam according to the second indication information from the first network device, the second network device can adjust the beam according to the third preset condition, which can reduce transmission overhead, avoid as much as possible the situation where the second network device cannot receive the second indication information and the beam is always the fourth beam, and improve the reliability of communication.

[0147] Optionally, the second network device may determine the moving speed of the terminal device within the coverage area of ​​the first network device according to one or more of the following parameters: Doppler frequency shift, or GPS speed.

[0148] Based on the above method, the present application proposes four possible embodiments for moving a terminal device from the coverage area of ​​a first network device to the coverage area of ​​a second network device:

[0149] In a first possible embodiment, when a first preset condition is met, the first network device adjusts the beam from the first beam to the second beam, and the terminal device within the coverage of the first network device accesses the first network device according to the second beam of the first network device; when a second preset condition is met, the first network device adjusts the beam from the second beam to the first beam. When a terminal device with a moving speed greater than or equal to the first preset threshold leaves the coverage of the first network device and enters the coverage of the second network device, if the number of terminal devices with a moving speed greater than or equal to the first preset threshold is greater than or equal to the second preset threshold, the second network device adjusts the beam from the third beam to the fourth beam, and the terminal device within the coverage of the second network accesses the second network device according to the fourth beam of the second network device; when the third preset condition is met, the second network device adjusts the beam from the fourth beam to the third beam.

[0150] In a second possible embodiment, when the first preset condition is met, the first network device adjusts the beam from the first beam to the second beam, and the terminal device within the coverage of the first network device accesses the first network device according to the second beam of the first network device. At the same time, the first network device sends the first indication information to the second network device, and the second network device can adjust the beam from the third beam to the fourth beam according to the first indication information from the first network device; when the second preset condition is met, the first network device adjusts the beam from the second beam to the first beam. When the terminal device with a moving speed greater than or equal to the first preset threshold leaves the coverage of the first network device and enters the coverage of the second network device, since the second network device is adjusted to the fourth beam in advance, the terminal device within the coverage of the second network device can access the second network device according to the fourth beam of the second network device; when the third preset condition is met, the second network device adjusts the beam from the fourth beam to the third beam.

[0151] In a third possible embodiment, when the first preset condition is met, the first network device adjusts the beam from the first beam to the second beam, and the terminal device within the coverage of the first network device accesses the first network device according to the second beam of the first network device. At the same time, the first network device sends the first indication information and the second indication information to the second network device, and the second network device can adjust the beam from the third beam to the fourth beam according to the first indication information from the first network device; when the second preset condition is met, the first network device adjusts the beam from the second beam to the first beam. When the terminal device with a moving speed greater than or equal to the first preset threshold leaves the coverage of the first network device and enters the coverage of the second network device, since the second network device is adjusted to the fourth beam in advance, the terminal device within the coverage of the second network device can access the second network device according to the fourth beam of the second network device; the second network device can adjust the beam from the fourth beam to the third beam according to the second indication information.

[0152] In a fourth possible embodiment, when the first preset condition is met, the first network device adjusts the beam from the first beam to the second beam, and the terminal devices within the coverage of the first network device access the first network device according to the second beam of the first network device, and at the same time, the first network device sends the second indication information to the second network device; when the second preset condition is met, the first network device adjusts the beam from the second beam to the first beam. When the terminal device with a moving speed greater than or equal to the first preset threshold leaves the coverage of the first network device and enters the coverage of the second network device, if the number of terminal devices with a moving speed greater than or equal to the first preset threshold is greater than or equal to the second preset threshold, the second network device adjusts the beam from the third beam to the fourth beam, and the terminal devices within the coverage of the second network device access the second network device according to the fourth beam of the second network device; the second network device may adjust the beam from the fourth beam to the third beam according to the second indication information.

[0153] based on Figure 5 The described embodiment, further, in the embodiment of the present application, the first network device can adjust the waveform of the terminal device according to the MCS order of the terminal device, and the method includes: the first network device determines the average MCS order corresponding to the terminal devices that meet the fourth preset condition within a preset time; if the average MCS order is greater than the third preset threshold, sending first configuration information to the terminal devices that meet the fourth preset condition; or, if the average MCS order is less than or equal to the third preset threshold, sending second configuration information to the terminal devices that meet the fourth preset condition.

[0154] Among them, the fourth preset condition is that the moving speed within the coverage area of ​​the first network device is greater than or equal to the first preset threshold; the first configuration information is used to indicate the CP-OFDM waveform; and the second configuration information is used to indicate the DFT-S-OFDM waveform.

[0155] Optionally, the third preset threshold may be determined according to an actual communication scenario or actual communication requirement.

[0156] Correspondingly, the terminal device can receive the first configuration information from the first network device and adjust the waveform to a CP-OFDM waveform; or, the terminal device can receive the second configuration information from the first network device and adjust the waveform to a DFT-S-OFDM waveform.

[0157] The terminal device can assign the CP-OFDM waveform or the DFT-S-OFDM waveform to any beam (wide beam or narrow beam) to realize data transmission.

[0158] In a possible embodiment, the first network device can collect the MCS orders of terminal devices whose moving speed is greater than or equal to a first preset threshold within a time period (a time period can be any time, for example, a day or an hour) within the coverage area of ​​the first network device, and then obtain the average MCS order.

[0159] Exemplarily, the MCS order of terminal devices within the coverage area of ​​the first network device can be input into a neural network to calculate the MCS order of terminal devices whose moving speed is greater than or equal to a first preset threshold, and then the weighted average of the MCS order, i.e., the average MCS order, is calculated.

[0160] For example, taking the average MCS order as 4 and the third preset threshold as 6, since the average MCS order is less than the third preset threshold, the first network device sends the first configuration information to the terminal device that meets the fourth preset condition.

[0161] For another example, taking the average MCS order as 8 and the third preset threshold as 6, since the average MCS order is greater than the third preset threshold, the first network device sends the second configuration information to the terminal device that meets the fourth preset condition.

[0162] Based on the above-mentioned method of configuring a waveform for a terminal device by a first network device, the first network device can determine the average MCS order of the terminal devices whose moving speed is greater than or equal to the first preset threshold within the coverage area of ​​the first network device within a preset time; when the average MCS order is greater than the third preset threshold, the first configuration information can be used to instruct the terminal device to use the CP-OFDM waveform for data transmission, which can reduce the transmission power of the terminal device and reduce power consumption; when the MCS order is less than or equal to the third preset threshold, the second configuration information can be used to instruct the terminal device to use the DFT-S-OFDM waveform for data transmission, which can increase the transmission power of the terminal device, avoid distortion, and improve communication performance. At the same time, sending the first configuration information or the second configuration information to the terminal device to fix the configuration waveform can avoid frequent reconfiguration of the waveform for the terminal device as much as possible, thereby reducing the risk of dropped calls of the terminal device, enabling the terminal device to obtain optimal performance, and improving the communication quality between the terminal device and the first network device.

[0163] Optionally, the first network device may perform waveform adaptive configuration on a terminal device within the coverage of the first network device and whose moving speed is less than a first preset threshold value according to the channel quality.
