The wireless terminal device may be a device that provides voice and/or data connectivity to a user, or an aircraft, handheld device, or other processing device connected to a wireless modem with wireless connectivity.
A terminal device, also called a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device including a wireless communication function (providing voice/data connectivity to a user), such as an aircraft, a handheld device, or an in-vehicle device with a wireless connection function, etc. Currently, examples of some terminal devices are: unmanned aerial vehicles (uncrewed aerial vehicle, UAV), mobile phones (mobile phones), tablet computers, notebook computers, palm computers, mobile internet devices (mobile internet device, MID), wearable devices, virtual Reality (VR) devices, augmented reality (augmented reality, AR) devices, wireless terminals in industrial control (industrial control), wireless terminals in the internet of vehicles, wireless terminals in the unmanned (self driving), wireless terminals in teleoperation (remote medical surgery), wireless terminals in smart grid (smart grid), wireless terminals in transportation safety (transportation safety), wireless terminals in smart city (smart city), or wireless terminals in smart home (smart home), and the like.

The beam used to receive the signal may be referred to as a receive beam (Rx beam), a spatial receive filter (spatial domain reception filter), a spatial receive filter (spatial reception filter), spatial receive parameters (spatial domain reception parameter) or spatial receive parameters (spatial reception parameter), spatial receive settings (spatial domain reception setting), or spatial receive settings (spatial reception setting). The uplink transmission beam may be indicated by any one of spatial relationship, uplink TCI-state, channel sounding reference signal (sounding reference signal, SRS) resource (indicating a transmission beam using the SRS). Thus, the uplink beam may also be replaced with SRS resources.
The transmit beam may refer to a distribution of signal strengths formed in spatially different directions after signals are transmitted through the antennas, and the receive beam may refer to a distribution of signal strengths of wireless signals received from the antennas in spatially different directions.
2. Measurement configuration: measurement objects, measurement intervals (GAPs), reporting configurations, trigger amounts, and measurement IDs may be included in the measurement configuration.
3. Measurement of GAP: measurement GAP is a period of time for a measurement terminal device to leave a current frequency point to measure other frequency points, and usually only inter-frequency measurement and inter-system measurement can relate to measurement GAP. However, co-frequency measurements may also require configuration of measurement GAPs when directional antenna measurements are employed.
4. Transmission configuration indication (transmission configuration indicator, TCI): the QCL is configured by the upper layer in the protocol through the TCI-state, and the parameters of the TCI-state are used for configuring the quasi co-location relationship between one to two downlink reference signals and the DMRS of the PDSCH, and are fields in the downlink control information (downlink control information, DCI) for indicating the quasi co-location of the PDSCH antenna ports.
5. Transmission receiving node (transmission reception point, TRP): (definition in relation to TRP:3GPP TR 38.912: antenna array with one or more antenna elements available to the network located at a specific geographical location for a specific area.). In the case of higher spectrum, since a network node (e.g. a base station) has limited coverage, the coverage radius of a cell is very small if defined by a conventional cell, so the concept of TRP is generally introduced in 5G, which corresponds to a conventional base station, but in some cases, one cell may cover more than one TRP and be covered by multiple TRPs in combination, thereby increasing the coverage radius of a cell and greatly reducing the continuous handover of terminal equipment on a cell.
6. The purpose of beam management is to establish and maintain a proper set of beams at the network device and terminal device to maintain a good wireless connection.
7. Omni-directional antenna: i.e. it appears that the radiation is uniform over 360 deg. in the horizontal pattern, the signal transmission is non-directional and can receive signals from and transmit signals to various angles. Omni-directional antennas are commonly used in communication systems in environments with close communication distances and large coverage areas.
8. Directional antenna: the radiation appears to have a range of angles in the horizontal pattern, the signal transmission is directional, and typically the signal can only be transmitted in one direction. Directional antennas are commonly used in communication systems in environments with long communication distances, small coverage areas, and high target densities.

Having described several possible scenarios to which the antenna management method provided in the present application is applied, the antenna management method provided in the embodiment of the present application is described below.
As shown in fig. 2, an embodiment of a method for antenna management provided in an embodiment of the present application includes:

In this embodiment of the present application, the first indication information and the second indication information may be represented by different parameters, or may be represented by different identifiers, for example: the first indication information and the second indication information may be represented by 0 or 1, and if the first indication information indicates an omni-directional antenna with 0, the second indication information indicates a directional antenna with 1. Conversely, if the first indication information indicates an omni-directional antenna with 1, the second indication information indicates a directional antenna with 0. Of course, the first instruction information and the second instruction information may be represented in other forms, and are not limited to the manner of being indicated by the 1-bit information listed here.
In this embodiment of the present application, the first measurement result may be a measurement result of the cell quality by the omni-directional antenna, for example: measurement of reference signal received power (reference signal receiving power, RSRP) of a cell by an omni-directional antenna. The second measurement may be a measurement of cell quality by the directional antenna, such as: measurement of RSRP of a cell by a directional antenna.
In this embodiment of the present application, the first measurement result and the second measurement result may be reported to the first network device through one measurement report. The first indication information and the second indication information may be reported to the first network device in the measurement report, or may be reported to the first network device through another separate signaling.
204. The first network device manages the omni-directional antenna according to the first measurement result and/or the directional antenna according to the second measurement result.
In the embodiment of the application, the terminal equipment is provided with the omni-directional antenna and the directional antenna, when the terminal equipment reports the measurement result to the first network equipment, the terminal equipment reports the measurement result of each of the omni-directional antenna and the directional antenna, and indicates the measurement result of the omni-directional antenna and the measurement result of the directional antenna through the first indication information and the second indication information. In this way, the first network device can manage the omni-directional antenna according to the measurement result of the omni-directional antenna, and manage the directional antenna according to the measurement result of the directional antenna, thereby realizing management of different antennas and improving the performance of antenna management.
Alternatively, in the embodiment of the present application, the first indication information may be included in the first measurement result. The second indication information may be included in the second measurement result.
In another possible embodiment, the first indication information and the second indication information may be located outside the first measurement result and the second measurement result, may be located in the same measurement report as the first measurement result and the second measurement result, or may be located in a signaling independent of the measurement report, where the association relationship between the first indication information and the second indication information and the first measurement result and the second measurement result may be indicated by the sequence of the first indication information and the second indication information.
Of course, the embodiments of the present application are not limited to the several possible manners listed herein, as long as the first indication information may indicate the relationship between the first measurement result and the omni-directional antenna, and the second indication information may indicate the relationship between the second measurement result and the directional antenna, and the manners in which the first indication information and the second indication information are reported to the first network device are not limited.
Optionally, before the step 201, the embodiment of the present application may further include steps 201a and 201b, or only include 201b, that is, the first network device is not required to send the query request, and the terminal device actively reports the capability information.
201a. The first network device sends a capability query request to the terminal device. Correspondingly, the terminal device receives a capability query request sent by the first network device.
201b, the terminal device sends capability information of the terminal device to the first network device. Correspondingly, the first network device receives the capability information of the terminal device sent by the terminal device.
The capability information of the terminal device includes first capability information, where the first capability information is capability information of the directional antenna, and a relationship between the first capability information and the directional antenna may be indicated by third indication information, and the third indication information may or may not be included in the first capability information.
The capability information of the terminal device may also include capability information of the omni-directional antenna.
In this embodiment of the present application, the capability information of the omni-directional antenna and the capability information of the directional antenna may be expressed in various manners in the capability information of the terminal device, and the following two expression manners are described as examples:
representation one: the capability information of the omni-directional antenna is a first set of transmission parameters, and the capability information of the directional antenna is a second set of transmission parameters.
1. The parameter names of the first set of transmission parameters are different from the parameter names of the second set of transmission parameters. In this case, the third indication information is a parameter name of a multiple-input multiple-output (MIMO) transmission parameter.
The body content of the first set of transmission parameters and the second set of transmission parameters may be substantially the same, mainly including MIMO-related parameters and Radio Frequency (RF) -related parameters.
The differences may be: the parameter names of the two sets of transmission parameters may be different, such as: the first set of transmission parameters is named MIMO-ParametersPerband, and the second set of transmission parameters is named MIMO-ParametersPerband-direction. Thus, the first set of transmission parameters may be indicated as transmission parameters of the omni-directional antenna by the parameter name MIMO-ParametersPerBand and the second set of transmission parameters may be indicated as transmission parameters of the directional antenna by the parameter name MIMO-ParametersPerBand-directional.
One possible representation of the format of the capability information of the terminal device and the capability information of the omni-directional antenna and the capability information of the directional antenna, and the distinction of the capability information of the omni-directional antenna and the capability information of the directional antenna, may be understood with reference to fig. 3.
As shown in fig. 3, the capability information of the terminal device may include a data header, capability information of an omni-directional antenna, capability information of a directional antenna, and other content of the capability information of the currently existing terminal device, which is not listed in this application. The capability information of the omni-directional antenna is represented by a first set of transmission parameters, wherein the first set of transmission parameters comprises a parameter name 1 and the content of the first set of transmission parameters. The capability information of the directional antenna is represented by a second set of transmission parameters, the second set of transmission parameters includes contents of a parameter name 2 and a second set of transmission parameters, the parameter name 1 is different from the parameter name 2, the first set of transmission parameters can be indicated to be transmission parameters of the omni-directional antenna through the parameter name 1, and the second set of transmission parameters can be indicated to be transmission parameters of the directional antenna through the parameter name 2, such as: the parameter name 1 is MIMO-ParametersPerband, and the parameter name 2 is MIMO-ParametersPerband-direction.
2. The bit information indicating the antenna in the first set of transmission parameters is different from the bit information indicating the antenna in the second set of transmission parameters. In this case, the third indication information is bit information.
The bit information of the indicating antenna in the first set of transmission parameters is 0, the bit information of the indicating antenna in the second set of transmission parameters is 1, or the bit information of the indicating antenna in the first set of transmission parameters is 1, and the bit information of the indicating antenna in the second set of transmission parameters is 0. Whether an omni-directional antenna or a directional antenna is indicated by 0 or 1 may be preconfigured in the first network device.
Of course, the bits representing the antennas may not be set in the first set of transmission parameters, and only the bits representing the directional antennas may be set in the second set of transmission parameters.
Another possible representation of the format of the capability information of the terminal device and the capability information of the omni-directional antenna and the capability information of the directional antenna, as well as the distinction between the capability information of the omni-directional antenna and the capability information of the directional antenna, may be understood with reference to fig. 4.
As shown in fig. 4, the capability information of the terminal device may include a data header, capability information of an omni-directional antenna, capability information of a directional antenna, and other content of the capability information of the currently existing terminal device, which is not listed in this application. The capability information of the omni-directional antenna is represented by a first set of transmission parameters, which have first bit information recorded on bits representing the antenna. The capability information of the directional antenna is represented by a second set of transmission parameters, which have second bit information recorded on bits representing the antenna. The first bit information may be used to indicate that the first set of transmission parameters are transmission parameters of an omni-directional antenna and the second bit information may be used to indicate that the second set of transmission parameters are transmission parameters of a directional antenna. The first bit information and the second bit information may be 0, 1 or 1, 0, respectively.
In this representation, the capability information of the directional antenna further includes a measurement interval (GAP), which is used to represent the time required for the directional antenna to rotate by a predetermined angle. Wherein the predetermined angle may be any one of 0 ° to 360 °. The measurement interval may be tens of milliseconds, hundreds of milliseconds, or more, such as: 100ms.
The second expression mode is: the capability information of the omni-directional antenna and the capability information of the directional antenna are included in a set of transmission parameters.
In the transmission parameter, the maximum number of beams of the omni-directional antenna is different from the maximum number of beams of the directional antenna.
In the second expression, the capability information of the omni-directional antenna and the capability information of the directional antenna are both included in the set of transmission parameters of MIMO-ParametersPerBand, but the set of transmission parameters includes not only the maximum beam number of the omni-directional antenna, such as: maxNumberRxBeam, also contains the maximum number of beams for the directional antenna, such as: maxNumberRxBeam-direction. Thus, the capability information of the omni-directional antenna and the directional antenna can be distinguished by maxNumberRxBeam and maxNumberRxbeam-direction.
If the maximum beam number of the omni-directional antenna is the same as the maximum beam number of the directional antenna, the omni-directional antenna and the directional antenna cannot be clearly distinguished, and indication information can be added in the set of transmission parameters to indicate the antenna associated with the maximum beam number of the directional antenna, for example: a field may be added to indicate or 1bit information may be added to indicate that one of the maximum beam numbers is the maximum beam number of the directional antenna, and of course, two indications may be used to indicate antennas corresponding to the two maximum beam numbers, respectively.
The format of the capability information of the terminal device and the capability information of the omni-directional antenna and the capability information of the directional antenna in this representation, and the difference between the capability information of the omni-directional antenna and the capability information of the directional antenna can be understood with reference to fig. 5. As shown in fig. 5, the capability information of the terminal device may include a data header, capability information of an omni-directional antenna, capability information of a directional antenna, and other content of the capability information of the currently existing terminal device, which is not listed in this application. The capability information of the omni-directional antenna and the capability information of the directional antenna are contained in a set of transmission parameters, wherein the transmission parameters comprise the maximum beam number of the omni-directional antenna and the maximum beam number of the directional antenna, such as: maxNumberRxBeam and maxNumberRxBeam-directed.
In this representation, the capability information of the directional antenna further includes a measurement interval (GAP), which is used to represent the time required for the directional antenna to rotate by a predetermined angle. Wherein the predetermined angle may be any one of 0 ° to 360 °. The measurement interval may be tens of milliseconds, hundreds of milliseconds, or more, such as: 100ms.
The above describes different ways of reporting capability information of a terminal device. After the terminal device reports the capability information, the first network device may determine appropriate measurement configurations for the omni-directional antenna and the directional antenna.
In a possible embodiment, the first network device may determine a first measurement configuration for the omni-directional antenna according to the capability information of the omni-directional antenna, and determine a second measurement configuration for the directional antenna according to the capability information of the directional antenna, where the first measurement configuration and the second measurement configuration are included in the measurement configuration sent by the first network device to the terminal device.
In another possible embodiment, the first network device may send fourth indication information to the terminal device, where the fourth indication information is used to indicate that the omni-directional antenna and the directional antenna share the same measurement configuration. The fourth indication information may be sent by a separate signaling or may be included in the measurement configuration.
After receiving the measurement configuration sent by the first network device, the terminal device may limit the measurement procedure when executing the step 202. The limiting modes can be two, and the following description is provided respectively:
the first limiting mode is as follows: defining the same cell can only use one type of antenna for measurements.
When the omni-directional antenna and the directional antenna both adopt the beam forming technology, one antenna can have a plurality of beams, and when the signal quality of one cell is measured, the signal quality of each beam can be measured first, and then the measurement result of the antenna on the cell is obtained according to the measurement result of each beam.
Taking the example that the omni-directional antenna and the directional antenna have 3 beams respectively, three beams of the omni-directional antenna are represented by beam 1, beam 2 and beam 3, and three beams of the directional antenna are represented by beam 4, beam 5 and beam 6.
When the omni-directional antenna is used for measurement, a measurement result of the beam 1, a measurement result of the beam 2 and a measurement result of the beam 3 are obtained, and the measurement result of the beam 1, the measurement result of the beam 2 and the measurement result of the beam 3 can be added and averaged to obtain a first measurement result of the omni-directional antenna for the cell.
Taking the example that the measurement result is the reference signal received power (reference signal receiving power, RSRP), the measurement result of beam 1 is denoted by RSRP1, the measurement result of beam 2 is denoted by RSRP2, the measurement result of beam 3 is denoted by RSRP3, and the first measurement result may be (rsrp1+rsrp2+rsrp3)/3. Of course, this is merely illustrative, and the weight may be applied during calculation, and the last measurement of the omni-directional antenna may be combined. Such as: the process of determining the first measurement may be represented by the following relationship:
F n ＝(1–a)*F n -1+a*M n
wherein M is n Is the most recent measurement, for example: may be (RSRP 1+RSRP2+RSRP 3)/3, fn is the measurement result to be updated after filtering, i.e. the first Measurement result, F n -1 is the last measurement and a is a weight, a value between 0 and 1.
When the directional antenna is used for measurement, the measurement result of the beam 4, the measurement result of the beam 5 and the measurement result of the beam 6 are obtained, and the measurement result of the beam 4, the measurement result of the beam 5 and the measurement result of the beam 6 can be added and averaged to obtain a second measurement result of the omni-directional antenna for the cell.
Taking the example that the measurement result is the reference signal received power (reference signal receiving power, RSRP), the measurement result of the beam 4 is denoted by RSRP4, the measurement result of the beam 5 is denoted by RSRP5, the measurement result of the beam 6 is denoted by RSRP6, and the second measurement result may be (rsrp4+rsrp5+rsrp6)/3. The process of introducing weights and determining a second measurement in combination with the last measurement may also be understood with reference to the introduction of the omni-directional antenna section.
When the signal quality of the cell is measured by using only the omni-directional antenna, only the first measurement result needs to be reported, and when the signal quality of the cell is measured by using only the directional antenna, only the second measurement result needs to be reported.
And a limiting mode II: for the same cell, both the omni-directional antenna and the directional antenna can be measured, and the plurality of measurement results of the same antenna can be limited to be combined.
When the omni-directional antenna and the directional antenna both adopt the beam forming technology, one antenna can have a plurality of beams, and when the signal quality of one cell is measured, the signal quality of each beam can be measured first, and then the measurement result of the antenna on the cell is obtained according to the measurement result of each beam.
Taking the example that the omni-directional antenna and the directional antenna have 3 beams respectively, three beams of the omni-directional antenna are represented by beam 1, beam 2 and beam 3, and three beams of the directional antenna are represented by beam 4, beam 5 and beam 6.
Since the omni-directional antenna and the directional antenna both measure the signal quality of the cell, 6 measurements are obtained, namely the measurement of beam 1, the measurement of beam 2 and the measurement of beam 3, and the measurement of beam 4, the measurement of beam 5 and the measurement of beam 6. When the terminal device determines the first measurement result and the second measurement result, the measurement result of the beam of each antenna needs to be selected, for example: in determining the first measurement result, the measurement result of beam 1, the measurement result of beam 2, and the measurement result of beam 3 of the omni-directional antenna are selected from the 6 measurement results. In determining the second measurement result, the measurement result of beam 4, the measurement result of beam 5 and the measurement result of beam 6 of the directional antenna are selected from the 6 measurement results.
The determination of the first measurement result and the second measurement result can be understood by referring to the description in the above-mentioned limiting mode one, and is not repeated here.
Because both antennas measure the signal quality of the cell, when reporting the measurement result, a first measurement result and a second measurement result need to be reported.
In the first and second limiting modes, the first measurement result is determined by taking the omni-directional antenna as an example using the beamforming technique, and when the omni-directional antenna does not use the beamforming technique, the combining process of the measurement results of the beams is not needed, and the measurement result of the omni-directional antenna is directly used as the final first measurement result, or is input as the latest measurement result to the relation F n ＝(1–a)*F n -1+a*M n In (1), F is calculated n As a first measurement result.
The use of which antenna to perform the beam measurement in the measurement process may depend on the implementation of the terminal device, or may be indicated by the network device according to the antenna capability information of the terminal device, that is, the first network device issues different configurations according to the antenna capability information when issuing the measurement configuration, such as the foregoing description of issuing the first measurement configuration for the omni-directional antenna and issuing the second measurement configuration for the directional antenna.
In the process of reporting the measurement results, the first indication information or the second indication information can be added in the measurement results of each cell to distinguish which antenna is the measurement result.
In this embodiment of the present application, the distinguishing of the measurement results may correspond to distinguishing of the antenna capability, that is, the capability information of the omni-directional antenna received by the first network device should correspond to the measurement result of the omni-directional antenna, and the capability information of the directional antenna received by the first network device should correspond to the measurement result of the directional antenna.
In this embodiment of the present application, after receiving at least one of the first measurement result or the second measurement result sent by the terminal device, the first network device may manage the omni-directional antenna or/and the directional antenna of the terminal device, that is, the step 204 may specifically include 204a and 204b.
204a. The first network device sends management information to the terminal device. Correspondingly, the terminal device receives the management information sent by the first network device.
The management information may include at least one of a direction in which the beam of the omni-directional antenna or/and the directional antenna is to be adjusted, an angle of adjustment, turning off the omni-directional antenna or the directional antenna, and when the terminal device is the unmanned aerial vehicle, the management information may further include at least one of a height at which the unmanned aerial vehicle flies, a posture of the unmanned aerial vehicle, and the like.
204b, the terminal device manages the omni-directional antenna or/and the directional antenna according to the management information.
The terminal device managing the omni-directional antenna or/and the directional antenna according to the management information means that the terminal device adjusts the beam direction of the omni-directional antenna or/and the directional antenna according to the management information, or turns off the omni-directional antenna or the directional antenna, and the like.
When both omni-directional and directional antennas employ beamforming techniques, the management information may configure an indication state (transmission configuration indicator state, TCI-state) for the transmission.
When the omni-directional antenna does not employ beamforming techniques and the directional antenna employs beamforming techniques, the management information may include at least one of TCI-state or scheduling parameters of the omni-directional antenna.
In this embodiment of the present application, the content of the management information is related to whether the omni-directional antenna and the directional antenna detect the second network device that can be the target TRP, and is described below.
1. When the omnidirectional antenna and the directional antenna both adopt the beam forming technology and the omnidirectional antenna and the directional antenna both detect the second network device, the first network device only needs to issue a TCI-state to indicate that the direction of the beam of the omnidirectional antenna and the direction of the beam of the directional antenna are adjusted to point to the second network device.
The beam adjustment direction of the omni-directional antenna can be adjusted by controlling the direction during beam forming, the beam adjustment direction of the directional antenna can be rotated, the directional antenna can be rotated by a certain angle, and the beam of the directional antenna is directed to the second network device.
2. The omni-directional antenna and the directional antenna both adopt beam forming technology, when one of the omni-directional antenna and the directional antenna detects the second network device, the first network device only needs to issue a TCI-state, and the first information in the TCI-state can indicate that the direction of the antenna detecting the second network device is adjusted to point to the second network device.
In this case, the TCI-state may further include second information, where the second information indicates that the antenna of the second network device is not detected, for example: if the directional antenna does not detect the second network device, the directional antenna may be instructed to be turned off, so that the energy consumption of the antenna may be reduced.
3. The omni-directional antenna does not adopt the beam forming technology, the directional antenna adopts the beam forming technology, and when the omni-directional antenna and the directional antenna both detect the second network device, the first network device needs to issue a TCI-state for the directional antenna and issue the scheduling parameters of the omni-directional antenna for the omni-directional antenna.
The scheduling parameter of the omni-directional antenna is used for indicating to switch the communication connection of the omni-directional antenna, and the scheduling parameter can include the identification of the target TRP, etc., so that the terminal device can disconnect the communication connection of the omni-directional antenna and the first network device, and establish the connection of the second network device and the omni-directional antenna.
The TCI-state issued for the directional antenna is used to indicate that the directional antenna is rotated by a certain angle so that the beam of the directional antenna is directed to the second network device.
4. The omni-directional antenna does not adopt the wave beam forming technology, the directional antenna adopts the wave beam forming technology, and when the omni-directional antenna detects the second network device, the first network device transmits the scheduling parameters of the omni-directional antenna for the omni-directional antenna.
In this case, the scheduling parameter may further include information for turning off the directional antenna, so that the terminal device may turn off the directional antenna, thereby reducing energy consumption.
5. The omni-directional antenna does not adopt the beam forming technology, the directional antenna adopts the beam forming technology, and when the directional antenna detects the second network device, the first network device issues a TCI-state for the directional antenna.
The first information in the TCI-state may indicate that the direction of the directional antenna is adjusted to point to the second network device.
The TCI-state can also comprise second information, and the second information indicates to close the omni-directional antenna, so that the energy consumption is reduced.
The above-described antenna management process may include several different cases, in which the terminal device is illustrated by way of example as a drone, and in fig. 6A to 6C, the omni-directional antenna and the directional antenna both employ beamforming techniques, and in fig. 7A to 7C, the omni-directional antenna does not employ beamforming techniques, and the directional antenna employs beamforming techniques.
It should be noted that in the embodiment of the present application, the second network device may be one network device, or may be a plurality of network devices, and the first network device may be one network device, or may be a plurality of network devices.
1. The omni-directional antenna and the directional antenna of the drone both detect the same target TRP.
This situation can be understood with reference to fig. 6A. As shown in fig. 6A, the scenario includes the drone 10, the network device 20, and the network device 30.
