Detailed Description
First, in order to facilitate understanding of the embodiments of the present application, some terms related to the embodiments of the present application will be described:
Beamforming: generally, electromagnetic waves have power loss when propagating in air, and the higher the frequency of the electromagnetic waves, the larger the loss, and the smaller the coverage range of the electromagnetic waves correspondingly. There is a need to improve coverage using multi-antenna techniques. Under the multi-antenna technology, due to interference and diffraction characteristics of electromagnetic waves, after signals with different amplitudes and phases transmitted by different antennas are overlapped, the energy in certain directions can be enhanced, and the energy in certain directions can be weakened. In this case the electromagnetic wave will radiate into a beam of a narrow width and in a certain direction. With this property of multiple antennas, the process of beamforming is interfered with, so that the width and direction of the beam that we want are formed, which is beamforming. The purpose of beam management techniques is to establish and maintain a suitable set of beams at the transmitting and receiving ends to maintain a good wireless connection, which mainly includes service beam selection and beam failure recovery.
Omni-directional antenna: it is generally meant that the signal pattern of the antenna is a 360 degree coverage antenna. For example, it is generally shown that the radiation is uniformly 360 ° in a horizontal pattern, which is commonly known as non-directivity, and a beam having a certain width in a vertical pattern, the smaller the lobe width, the larger the gain. Fig. 2 is a schematic diagram of a terminal using an omni-directional antenna to communicate with a network device.
Directional antenna: typically, the signal pattern of the antenna covers only a certain angular range. For example, 30 degrees. For example, directional antennas generally focus radio frequency energy in a particular direction. As the gain of the directional antenna increases, the coverage distance increases, but the effective coverage angle decreases. For a directional antenna, the lobe will be pushed in a certain direction and little energy is present at the back of the antenna. A schematic diagram of a terminal communicating with a network device using a directional antenna is shown in fig. 3.
Fig. 1 is a schematic diagram illustrating one possible, non-limiting system. As shown in fig. 1, the communication system 1000 includes a radio access network (radio access network, RAN) 100 and a Core Network (CN) 200.RAN 100 includes at least one RAN node (e.g., 110a and 110b, collectively 110 in fig. 1) and at least one terminal (e.g., 120a-120j, collectively 120 in fig. 1). Other RAN nodes may also be included in the RAN100, such as wireless relay devices and/or wireless backhaul devices (not shown in fig. 1), and the like. Terminal 120 is connected to RAN node 110 wirelessly. RAN node 110 is connected to core network 200 by wireless or wired means. The core network device in the core network 200 and the RAN node 110 in the RAN100 may be different physical devices, or may be the same physical device integrated with the core network logic function and the radio access network logic function. The following description will be made taking a terminal as an example of a UAV and an access network device as an example of a base station. UAVs are equipped with directional antennas or multiple pairs of antennas of different capabilities. For example, in one possible scenario, a UAV is equipped with a set of directional antennas and a set of omni-directional antennas.
The communication system may support, for example, a communication system of 2G,3G,4G, or 5G (sometimes also referred to as new radio, NR) access technology, a wireless fidelity (WIRELESS FIDEL ITY, wiFi) system, a third generation partnership project (3rd generation partnership project,3GPP) related cellular system, a communication system supporting convergence of multiple wireless technologies, or a future-oriented evolution system.

The network device in the present application comprises, for example, an access network device, and/or a core network device. The access network device is a device with a wireless transceiving function and is used for communicating with the terminal. The access network device includes, but is not limited to, a base station (BTS, node B, eNodeB/eNB, or gNodeB/gNB), a transceiver point (TRANSMISS ION RECEPT ION POINT, TRP), a base station for subsequent evolution of 3GPP, an access Node in a WiFi system, a wireless relay Node, a wireless backhaul Node, and the like in the above communication system.

A base station may comprise one or more co-sited or non-co-sited transmission reception points. The network device may also be a centralized unit (central ized unit, CU), and/or a Distributed Unit (DU). The network device may also be a server, a wearable device, or an in-vehicle device, etc. For example, the network device in the V2X technology may be a Road Side Unit (RSU). An access network device will be described below taking a base station as an example. The communication system may comprise a plurality of network devices, which may be the same type of base station or different types of base stations. The base station may communicate with the terminal device or may communicate with the terminal device through the relay station. A terminal device may communicate with multiple base stations in different access technologies. The core network equipment is used for realizing the functions of mobile management, data processing, session management, policy and charging and the like. The names of devices implementing the core network function in the systems of different access technologies may be different, and the present application is not limited thereto. Taking a 5G system as an example, the core network device includes: an access and mobility management function (ACCESS AND mobi L ITY MANAGEMENT funct ion, AMF), a session management function (sess ion management funct ion, SMF), or a user plane function (user plane funct ion, UPF), etc.

In the technical solution provided in the embodiment of the present application, the device for implementing the function of the network device is exemplified by the network device, and the technical solution provided in the embodiment of the present application is described.
The data transmission method provided by the embodiment of the application is specifically described below with reference to the accompanying drawings. It should be noted that, in the following embodiments of the present application, a name of a message between each network element or a name of each parameter in a message is only an example, and in specific implementations, other names may also be used, which is not limited in particular by the embodiments of the present application.
Mobile communication systems are designed mainly for terrestrial UEs, but with the popularity of UAVs, the measurement mechanisms for UAVs are increasingly being discussed. The communication environment of the UAV in the air is very different from the ground, firstly, because the base station radiates electromagnetic waves towards the ground, the signals in the air are basically ground signal reflection and beam side lobes of the base station, and therefore, the signals received by the UAV are weaker. In addition, since the UAV is mainly based on Los path in the air, the UAV can receive more base station signals. In this case, in the densely deployed base station area, the UAV may cause serious uplink interference if it is equipped with an omni-directional antenna. In order to mitigate uplink interference caused by the UAV to the base station, one possible solution is to introduce directional antennas on the UAV to reduce the UAV interference to surrounding base stations. Thus, the UAV may be equipped with multiple antennas of different capabilities at the same time, e.g., the UAV is equipped with an omni-directional antenna and a directional antenna. When the UAV is equipped with multiple antennas with different capabilities at the same time, how the UAV manages the multiple antennas with different capabilities is a problem to be solved because the interference caused by the different antennas to surrounding base stations is different.
The application provides a method for switching antennas of unmanned aerial vehicles, which introduces how to manage antennas of UAVs, for example, under what conditions the UAVs switch antennas; how the different antennas are configured when the UAV switches antennas; or after switching the antenna, on the measurement results. By the method, the antennas with different capacities of the unmanned aerial vehicle can be managed, and the communication performance of the unmanned aerial vehicle is improved.
Fig. 4 is a schematic diagram of a communication method 400 according to an embodiment of the present application, which is used to introduce an antenna switching method of a terminal (hereinafter, a terminal is taken as an example of a UAV to describe the terminal), so as to improve communication performance of an unmanned aerial vehicle.
As shown in fig. 4, the method 400 may include the following steps.
S410: the UAV communicates using a first antenna, the UAV including a first antenna and a second antenna.
It will be readily appreciated that communicating does not limit the UAV to having access to the network device, and may include situations where the UAV is not in access with the network device.
In one possible implementation, the UAV establishes a connection with the network device, and the UAV communicates with the network device using a first antenna.
In another possible implementation, the UAV does not establish a connection with the network device, or is attempting to establish a connection with the network device, the UAV communicates using the first antenna.
The UAV including the first antenna and the second antenna is understood to be antennas where the UAV has (or is referred to as being equipped with) a plurality of different capabilities. For example, the first antenna is an omni-directional antenna and the second antenna is a directional antenna; or the first antenna is a directional antenna, and the second antenna is an omni-directional antenna; of course, the UAV may also have multiple omni-directional antennas or multiple directional antennas, with the first antenna being a first directional antenna and the second antenna being a second directional antenna, where the antenna capabilities of the first and second directional antennas are different. Or the first antenna is a first omni-directional antenna, and the second antenna is a second omni-directional antenna, wherein the antenna capacities of the first omni-directional antenna and the second omni-directional antenna are different.
For example, when the UAV is equipped with both a directional antenna and an omni-directional antenna, and the omni-directional antenna is enabled for communication.
S420: the UAV determines to turn on the second antenna.
That is, the UAV may determine to turn on the second antenna for communication when using the first antenna for communication.
The UAV may determine to turn on the second antenna in a number of ways, for example, the UAV may autonomously determine to turn on the second antenna, and the UAV may also determine to turn on the second antenna by interacting with the network device. The condition for specifically determining to turn on the second antenna may also be various, for example, the UAV determines to turn on the second antenna according to one or more of its own measurement information, configuration information of the network device, pre-configuration information, and indication information.
For example, the UAV determines to turn on the second antenna based on first information including first measurement information including one or more of quality information, altitude information, speed information, area information of the cell, and/or second indication information. The second indication information is used for indicating to turn on the second antenna. The first measurement information may be understood as measurement information of the UAV itself, which may also be referred to as measurement information measured by the UAV.
In one possible implementation, the UAV determines to turn on the second antenna based on the quality information of the cell. The quality information of the cell includes one or more of quality information of a serving cell of the UAV, quality information of neighboring cells, or measured quality information of the cell. The neighboring cell may be a neighboring cell measured by a UAV. Serving cell (to be complemented). The measured cell may be a cell measured using the first antenna.
Optionally, the UAV determines to turn on the second antenna according to the quality information and the threshold information of the cell. The threshold information includes one or more of threshold information corresponding to a serving cell, threshold information corresponding to a neighboring cell, and a first threshold.
For example, the UAV determines to turn on the second antenna when the quality of the serving cell is below threshold information (described as threshold a for example) corresponding to the serving cell and/or the quality of the neighboring cell is below threshold information (described as threshold B for example) corresponding to the neighboring cell. The threshold information that the quality of the serving cell is lower than the corresponding serving cell may be replaced by the quality of the serving cell is lower than the threshold a plus a first offset, where the first offset may be a positive number or a negative number. The quality of the neighboring cell below the threshold value information corresponding to the neighboring cell may be replaced by the quality information of the neighboring cell below the threshold value B plus a second offset, where the second offset may be a positive number or a negative number, or the number of neighboring cells whose quality information is above the threshold value B may be replaced by less than a first value, for example, the first value is 2.
For another example, the UAV determines to turn on the second antenna based on the measured quality information of the cell being below a first threshold.
Alternatively, the threshold information, the first offset, the second offset, and the first value may be network device configured, or pre-defined by a protocol, or determined by a UAV.
In yet another possible implementation, the UAV determines to turn on the second antenna based on the UAV reaching a corresponding altitude, speed, or reaching a particular area. For example, the UAV determines to turn on the second antenna based on one or more of altitude information, speed information, area information, and first configuration information.
The altitude information includes altitude information of the UAV, which may be altitude value information or altitude range (may also be referred to as altitude section) information, and may be absolute altitude or relative altitude. Exemplary altitude information includes UAV altitude of 200m; or the altitude information includes a height of the UAV greater than 100m and less than 200m.
The speed information includes speed information of the UAV, which is illustratively current speed information of the UAV or average speed information, maximum speed information, or minimum speed information of the UAV over a period of time.
The area information includes the cell coverage of the network device, or tracking area range, or actual geographical location information such as the no-fly area information specified by the administration. For example, the zone information includes that the UAV is in zone 1.
The first configuration information includes one or more of altitude configuration information, speed configuration information, or area configuration information. Specifically, the first configuration information may be configured by the network device (for example, the network device is described as a base station) in advance, for example, the base station configures the first configuration information for the UAV at the time of initial access. Or the first configuration information is preconfigured in the UAV. Alternatively, the first configuration information may include one or more sets of corresponding parameters, such as using an omni-directional antenna at 100m, using a directional antenna at 200m, and so on. Or the first configuration information is obtained from other network elements, which may be, for example, UAV controllers or UAV controlling network elements. The first configuration information is either preconfigured, predefined by a protocol, or determined by the UAV.
In yet another possible embodiment, the UAV determines to turn on the second antenna based on the second indication information
The second indication information instructs the UAV to turn on the second antenna. Optionally, the UAV receives second indication information from the network device. The embodiment of the application does not limit the content or the indication mode of the second indication information. For example, the second indication information may be bit information.
The multiple ways in which the UAV determines to turn on the second antenna may be used alone, i.e., the UAV may turn on the second antenna using one of the ways, or any two or more of the multiple ways may be used in combination, i.e., the UAV may determine to turn on the second antenna in a combination of the multiple ways, which may improve the accuracy of determining to turn on the second antenna. The UAV may determine whether to turn on the second antenna by any of the methods described above, and may be determined by the UAV itself, or may be specified by a protocol. Or, in addition to the above, the UAV may determine to turn on the second antenna in other manners, and the UAV determines to turn on the second antenna in a manner that is not limited by the embodiment of the present application.
It is readily appreciated that the method may also include the network device determining that the UAV uses the second antenna.
The network device determining that the UAV uses the second antenna may be referred to as the network device determining that the UAV needs to perform a handoff of the antenna, or as determining to send second indication information to the UAV, or as the network device determining to communicate with the UAV through the second antenna of the UAV, or as the network device determining that the UAV satisfies an antenna handoff condition.
The network device may determine that the UAV uses the second antenna in a number of ways. For example, the network device may autonomously determine, and the network device may also determine by interacting with the UAV. For example, the network device determines that the UAV uses the second antenna based on one or more of its own measurement information, UAV indication information, and UAV request information.
For example, the network device determines from the second information that the UAV uses the second antenna.
Wherein the second information includes one or more of first indication information, first request information, and second measurement information.
The first indication information is used for indicating that the UAV has started the second antenna;
Optionally, in one possible manner, the first request information is used to instruct the UAV to request to turn on the second antenna. The embodiment of the application does not limit the content of the first indication information and the first request information, for example, the first indication information or the first request information includes the identification of the second antenna.
Optionally, in yet another possible manner, the first request information is used to indicate first measurement information of the UAV, where the first measurement information includes one or more of quality information, altitude information, speed information, and area information of the cell. The first request information may be sent periodically, or may be sent to the network device for requesting to turn on the second antenna after the UAV determines that the UAV itself satisfies the condition of turning on the second antenna. The network device may determine whether the terminal uses the second antenna based on an internal implementation of the network device after receiving the first request information. For example, the network device, upon receiving the first measurement information, determines from the first measurement information that the UAV uses the second antenna. Regarding the first measurement information and the manner in which the UAV determines itself to satisfy the condition of turning on the second antenna, reference may be made to the UAV in step S420 described above for determining a description of turning on the second antenna based on the first measurement information. The method of determining, by the network device, that the UAV uses the second antenna according to the first measurement information is similar to the method of determining, by the UAV, to turn on the second antenna according to the first measurement information, except that the network device determines according to the first measurement information after obtaining the first measurement information from the UAV, which is not described in detail in the embodiments of the present application.
The second measurement information includes one or more of serving cell information, interference information, or deployment information of the UAV. The service cell information of the UAV comprises load information of the service cell of the UAV, and the interference information comprises uplink interference information detected by the network equipment. The deployment information includes deployment information of the network device. For example, the network device determines that the load of the UAV serving cell is too high or the detected uplink interference is too strong according to the second measurement information, or the network device is deployed in a dense area, and the network device determines that the UAV uses the second antenna.
The above ways in which the network device determines that the UAV uses the second antenna may be applied alone, i.e., the network device may determine using one of the ways, or any two or more of the above ways may be applied in combination, i.e., the network device may determine in a comprehensive plurality of ways, which may improve the accuracy of the determination. Whether the network device determines that the UAV uses the second antenna in any of the manners described above may be determined by the network device itself or may be specified by a protocol. Or in addition to the above, the network device may determine that the UAV uses the second antenna in other manners, and the embodiment of the present application is not limited to the manner in which the network device determines that the UAV uses the second antenna.
In one possible approach, after the UAV turns on the second antenna, the UAV may turn off the first antenna or may choose to continue using the first antenna.
In one possible approach, the UAV autonomously determines to turn off the first antenna. That is, after the UAV turns on the second antenna, the UAV turns off the first antenna. Optionally, after turning off the first antenna, the UAV sends an indication information to the network device indicating that the first antenna has been turned off. Accordingly, the network device receives indication information from the UAV indicating that the first antenna has been turned off.
In one possible approach, the network device determines to turn off the first antenna. The network device sends indication information to the UAV indicating that the UAV closes the first antenna, and the UVA receives the indication information from the network device indicating that the UAV closes the first antenna. The UAV turns off the first antenna according to the indication information.
It is readily understood that the network device may be configured to send, to the UAV, the indication information indicating that the UAV turns off the first antenna after receiving the indication information sent by the UAV to indicate that the second antenna is turned on. Or the network device may be configured to send, to the UAV, indication information indicating that the UAV turns on the second antenna, simultaneously or after sending, to the UAV, indication information indicating that the UAV turns off the first antenna.
Optionally, the method further includes S430, the UAV communicating using a second antenna.
In one possible approach, the UAV communicates using a second antenna, the first antenna being turned off.
In yet another possible manner, the first antenna and the second antenna are used to communicate with each other. For example, uplink communication is performed with the network device using the first antenna, and downlink communication is performed with the network device using the second antenna; or communicate with the network device using a first antenna and make measurements using a second antenna.
The information sent by the network device to the UAV in the embodiment of the present application may be carried in a radio resource control (radio resource control, RRC) message, a media access control (MEDIA ACCESS) Control Element (CE), or downlink control information (downl ink control informat ion, DCI) and other messages to be sent to the UAV.
It will be readily appreciated that the method may also include processing of the measurement results by the UAV when switching antennas, how the different antennas are configured, or after switching antennas. This section may be referred to in the description of the embodiments of fig. 5 and/or fig. 6.
According to the method, when the terminal is provided with the first antenna and the second antenna, the terminal autonomously determines to start the second antenna or starts the second antenna according to the indication of the network equipment, so that the management efficiency of the second antenna is improved, and the communication performance of the terminal is improved.
Fig. 5 is a diagram illustrating how to determine configuration information of an antenna after antenna switching of a terminal (hereinafter, the terminal is taken as an example for UAV) according to an embodiment of the present application, so as to improve communication performance of an unmanned aerial vehicle.
510: The UAV switches from the first antenna to the second antenna. Wherein the UAV includes a first antenna and a second antenna. The UAV may communicate via the first antenna and/or the second antenna.
It will be readily appreciated that the embodiment shown in fig. 5 may be combined with the embodiment of fig. 4, for example, one possible implementation of 510 is 510 comprising 410 and 420.
520: The UAV determines second configuration information for the second antenna.
For example, when the UAV switches from the first antenna to the second antenna, it may also be referred to as when the UAV determines to turn on the second antenna after turning on the first antenna (or when the UAV has turned on the second antenna), the UAV determines second configuration information for the second antenna. It is easy to understand that the embodiment of the application does not limit the order of determining to start the second antenna by the UAV and determining the second configuration information by the UAV, and may be determined simultaneously, or may be determined after the UAV determines to start the second antenna, or may be determined after the UAV determines the second configuration information to start the second antenna. Referring to the description of step S403, the present application is not limited to whether the first antenna is turned off after the second antenna is turned on.
In one possible approach, the UAV determines that the second antenna applies the first configuration information of the first antenna. That is, the first antenna and the second antenna take the same configuration information, and the first configuration information of the first antenna is the same as the second configuration information. Optionally, the UAV indicates to the network device that the second antenna and the second antenna apply the same set of configurations. Or alternatively, the UAV determines that the second configuration information is the same as the first configuration information based on the indication information from the network device. For example, the network device may send an indication to the UAV that the second antenna applies the configuration of the first antenna when it is known or determined that the second antenna is on.
In yet another possible manner, the UAV determines second configuration information for the second antenna based on pre-configuration information or configuration information from the network device. Alternatively, the second configuration information is different from the first configuration information, that is, the second antenna may be configured separately. Alternatively, the second configuration information may be pre-configured in the UAV. Or the second configuration information is network device configured. For example, as the network device may include second configuration information and/or first configuration information in a configuration that is issued when the UAV initially accesses, the first configuration information is applied when the UAV uses the first antenna, and the second configuration information is applied when the UAV uses the second antenna. Or after the UAV is switched to the second antenna, sending indication information to the network equipment, indicating that the UAV is switched to the second antenna currently, and determining whether to issue the first configuration information and/or the second configuration information by the network equipment.
Optionally, the UAV determines the power of the second antenna.
In one possible implementation, the UAV determines the power of the second antenna from the power of the first antenna. It is understood that the conversion is based on the power between the first antenna and the second antenna. Specifically, assuming that the transmitting power of the first antenna is a baseline, after the UAV switches to the second antenna, performing power conversion through a correlation coefficient, if the conversion coefficient is α, multiplying the transmitting power of the first antenna by α is the power of the second antenna. The embodiments of the present application are not limited in the manner in which the power of the second antenna is determined based on the power of the first antenna, but are merely examples herein.
Illustratively, the second configuration information includes one or more of the following: measurement interval, measurement period, or transmit power. It is easy to understand that the second configuration information may also include other information, and embodiments of the present application are not limited.
According to the method, when the UAV is provided with different types of antennas, after the UAV switches the antennas, the related antenna configuration can be selected to be actively applied, or the related configuration can be issued by the base station, and optionally, the UAV performs power conversion, so that the corresponding configuration can be determined after the antennas are switched.
Fig. 6 is a diagram illustrating how to perform measurement after antenna switching of a terminal (hereinafter, the terminal is taken as an example for UAV) according to an embodiment of the present application, so as to improve communication performance of an unmanned aerial vehicle.
610: The UAV switches from the first antenna to the second antenna. Wherein the UAV includes a first antenna and a second antenna. The UAV may communicate via the first antenna and/or the second antenna. Reference may be made to the relevant description of step 510.
620: The UAV sends the measurement results to the network device. Accordingly, the network device receives measurements from the UAV.
For example, the UAV sends a measurement report to the network device, the measurement report including the measurement results therein. The measurement may include information measured by the UAV, for example, the measurement may include one or more of altitude information, speed information, and position information of the UAV.
Optionally, the UAV clears the measurement using the first antenna measurement (which may also be referred to as a measurement prior to antenna switching or a historical measurement). For example, after the UAV measures a cell satisfying the condition through the first antenna, the cell is added to the trigger cell list, and after the UAV switches from the first antenna to the second antenna, the UAV clears the cell in the trigger cell list that was added after the measurement through the first antenna. Or the UAV chooses to report the measurement results before the antenna switching to the network equipment, and further clears the measurement results before the antenna switching. Or not clear the measurements prior to antenna switching, the UAV indicates in the measurement report which measurements are historical measurements and which measurements are measurements measured after antenna switching. The present application is not limited to the manner of indication, and for example, indication may be performed by means of bits, bit 1 indicates that the measurement result is a history measurement result, and bit 0 indicates that the measurement result is a measurement result after switching the antenna. The measurement result may also be referred to as measurement information. That is, the network device receives measurement result indication information from the UAV, the measurement result indication information being used to indicate an antenna to which the measurement result corresponds, or the measurement result indication information being used to indicate that the measurement result is a measurement result before or after the UAV uses the second antenna.
Optionally, after antenna switching, the UAV reports the measurement result to the network device, where the measurement result may include the measurement result of the cell after antenna switching, for example, information of the UAV such as height, speed, and position. The measurement reporting process may be indicated by the network device or autonomously determined by the UAV. If the indication is sent by the network equipment, the UAV sends indication information firstly, the indication information is used for indicating that the antenna is switched or the measurement result after the antenna is switched is available, and the network equipment indicates the UAV to report the measurement result in response to the indication information.
By this method, the UAV is equipped with both directional and omni-directional antennas, and after the UAV performs an antenna switch, the UAV can choose to clear the measurement before or not clear, indicate in the measurement report which are the measurement before the antenna switch, or which are the measurement after the antenna switch.

When data is transmitted to the terminal, the radio frequency circuit receives a radio frequency signal through the antenna, the radio frequency signal is further converted into a baseband signal, and the baseband signal is output to the processor, and the processor converts the baseband signal into data and processes the data.

The baseband processor may also be expressed as a baseband processing circuit or a baseband processing chip. The central processing unit may also be expressed as a central processing circuit or a central processing chip. The function of processing the communication protocol and the communication data may be built in the processor, or may be stored in the storage unit in the form of a software program, which is executed by the processor to realize the baseband processing function.
