The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of base station capable devices may vary, for example in LTE systems, called enodebs or enbs; in the 5G NR system, it is called gNodeB or gNB.

Fig. 2 shows a flowchart of a beam management method provided by an exemplary embodiment of the present disclosure. The method can be applied to the terminal shown in fig. 1, and the method comprises the following steps:
step 202, determining a target beam management parameter according to the moving speed of the terminal, wherein the target beam management parameter is a beam management parameter corresponding to the moving speed;
since the terminal is a mobile terminal, it is carried by the user wherever possible. Alternatively, the terminal acquires its own moving speed by a built-in sensor. Built-in sensors include, but are not limited to: global positioning chip, acceleration sensor or six-axis acceleration sensor. In this embodiment, how the terminal obtains its own movement speed is not limited, and other possible manners such as a base station-based triangulation method, a vehicle networking terminal-based triangulation method, and the like may be used.
The terminal determines different beam management parameters according to different moving speeds. Optionally, at least two moving speed intervals are provided, and different moving speed intervals correspond to different beam management parameters.
In one example, the at least two travel speed intervals include: medium speed (medium speed) intervals and high speed (high speed) intervals. When the moving speed of the terminal belongs to a medium speed interval, adopting beam management parameters corresponding to the medium speed interval; when the moving speed of the terminal belongs to the high-speed zone, adopting the beam management parameters corresponding to the high-speed zone.
In one example, the at least two travel speed intervals include: a low speed section, a medium speed section and a high speed section. When the moving speed of the terminal belongs to a low-speed interval, adopting beam management parameters corresponding to the low-speed interval; when the moving speed of the terminal belongs to a medium speed interval, adopting beam management parameters corresponding to the medium speed interval; when the moving speed of the terminal belongs to the high-speed zone, adopting the beam management parameters corresponding to the high-speed zone.
It should be noted that the movement speed of the terminal considered herein may be an absolute movement speed of the terminal, for example, when the network device is stationary, the movement speed of the terminal is the absolute movement speed of the terminal; the moving speed of the terminal may also be the relative moving speed of the terminal, for example, when the vehicle is in communication with the internet of vehicles, both vehicle-mounted devices may move, and then the moving speed of the terminal is the relative moving speed of the vehicle-mounted terminal and the vehicle-mounted terminal on the opposite side of the communication.
In one example, the beam management parameters include at least one of the following:
1. reference signals or reference signal sets for beam measurements;
the reference signal is a measurement object of beam measurement. The types of reference signals include: SSB or CSI-RS.
The reference signal is one or more. When the measurement object is a plurality of reference signals, it may be referred to as a reference signal set.
2. The number of reference signals reported in the beam measurement result;
the number of reported reference signals may be: 1. 2, 4, 8 or 16 … ….
3. The number of bits of the measurement value reported in the beam measurement result;
the measurement values need to be reported in the beam measurement results. The measured value is represented by a bit codeword of n bits. The bit overhead corresponding to different numbers of bits is different. By reducing the number of bits occupied when reporting the measurement value of each reference signal, the signaling overhead can be reduced.
4. Reporting period of beam measurement results.
Different moving speeds (intervals) correspond to different reporting periods. Alternatively, the faster the movement speed, the smaller the reporting period.
Step 204, beam management is performed according to the target beam management parameters.
And the terminal performs beam measurement according to the target beam management parameters, namely, performs measurement on reference signals corresponding to the beam, and obtains a beam measurement result. And the terminal reports the beam measurement result to the network equipment. And the network equipment determines a sending beam when sending downlink data according to the beam measurement result, and informs the terminal of the information of the sending beam.
The terminal determines its own reception beam according to the information of the transmission beam. And the terminal receives downlink data sent by the network equipment by adopting a receiving beam.
In summary, according to the method provided in the present embodiment, the target beam management parameter is determined according to the moving speed of the terminal, and the beam management is performed according to the target beam management parameter. Because different mobile speeds can correspond to different beam management parameters, when the mobile speed of the terminal is high, reasonable beam management parameters can be adopted to reduce signaling overhead and reduce time delay.
There are two different implementations of step 202 described above:
a first possible implementation: there are multiple sets of beam management parameters, and the target beam management parameters are determined from the multiple sets of beam management parameters according to the moving speed of the terminal.
A second possible implementation: there is a set of basic beam management parameters, and the target beam management parameters are generated based on the basic beam management parameters according to the moving speed of the terminal.
A first possible implementation is described below using the embodiment of fig. 3:
fig. 3 shows a flowchart of a beam management method provided by another exemplary embodiment of the present disclosure. The method can be applied to the terminal shown in fig. 1, and the method comprises the following steps:
step 302, determining target beam management parameters in at least two groups of beam management parameters according to the moving speed of the terminal;
the terminal determines at least two sets of beam management parameters, each set of beam management parameters corresponding to a respective movement speed (or movement speed interval). Table one exemplary shows the correspondence between the movement speed interval and the beam management parameter.
List one
| Travel speed interval | Beam management parameters |
| Low speed interval [ v1, v2 ] | First beam management parameter |
| Intermediate speed interval [ v2, v3 ] | Second beam management parameters |
| High speed interval [ v3, v 4] | Third beam management parameter |
At least two groups of beam management parameters correspond to different moving speed intervals.
In one design, the at least two sets of beam management parameters are terminal-built, such as factory settings; in another design, the at least two sets of beam management parameters are configured by the network device to the terminal.
Taking any two intervals in multiple groups of beam management parameters as a first interval and a second interval as an example: when the moving speed belongs to a first interval, the terminal determines a first beam management parameter in at least two groups of beam management parameters as a target beam management parameter; and when the moving speed belongs to a second interval, the terminal determines a second beam management parameter in at least two groups of beam management parameters as a target beam management parameter.
Depending on the content of the beam management parameters, exemplary implementations are as follows:
1. taking the example that the beam management parameters include a reference signal set: the network equipment configures a plurality of groups of reference signal sets to the terminal, and different reference signal sets correspond to different moving speed intervals. When the moving speed of the terminal belongs to a low-speed interval, the terminal uses a reference signal set 1; when the moving speed belongs to the middle speed interval, the reference signal set 2 is used; when the moving speed belongs to the high speed section, the reference signal set 3 is used. For example, the movement speed may be further subdivided, such that a greater number of reference signal sets are required for different movement speed intervals. Such as: for each reference signal corresponding to a higher moving speed, the wider the beam used when the network device transmits, then the fewer the number of reference signals in the set of beam reference signals corresponding to the higher moving speed.
2. Taking the number of reported reference signals as an example, the beam management parameters include: the network equipment configures a plurality of upper limit numbers for the terminal, wherein the upper limit numbers refer to the limit numbers of the reported maximum reference signals when the terminal reports the beam measurement results each time. The different upper limits of the number correspond to different moving speed intervals. Optionally, the larger the moving speed is, the more the number of the reported reference signals is.
Optionally, the upper limit of the number includes: 1. 2, 4, 8 and 16. The upper limit of the number of the terminal when reporting the reference signal is 2 when the moving speed belongs to the low-speed interval; when the moving speed belongs to the middle speed interval, the upper limit of the number of reporting the reference signals is 4; when the moving speed belongs to the high-speed section, the upper limit of the number of reporting the reference signals is 16.
In another implementation, the greater the movement speed, the fewer the number of reference signals reported.
Optionally, the upper limit of the number includes: 1. 2, 4, 8 and 16. The upper limit of the number of the terminal when reporting the reference signal is 8 when the moving speed belongs to a low-speed interval; when the moving speed belongs to the middle speed interval, the upper limit of the number of reporting the reference signals is 4; when the moving speed belongs to the high-speed section, the upper limit of the number of reporting the reference signals is 2.
3. Taking the example that the beam management parameters include the number of bits of the measurement value reported by the beam measurement result:
the measurement values need to be reported in the beam measurement results. The measured value is represented by a bit codeword of n bits. The bit overhead corresponding to different numbers of bits is different. By reducing the number of bits occupied when reporting the measurement value of each reference signal, the signaling overhead can be reduced.
For example, the measurement value of the reference signal with the highest L1-RSRP is represented by 7bit code words (within the range of (-140, -44) dBm, the difference between every two adjacent bit code words is 1dB, i.e. the step size between the two adjacent bit code words is 1 dB), and the measurement value of the other reference signals is represented by 4bit and the difference value between the two adjacent bit code words is 2dB, i.e. the step size between the two adjacent bit code words is 2 dB. Then to reduce the signaling overhead the step size between every adjacent two bit codewords can be increased, e.g. the larger the speed, the larger the step size, thus reducing the number of bits.
For example, when the moving speed of the terminal belongs to a low-speed interval, determining the bit number of the bit code word when reporting by using a smaller step size 1; when the moving speed belongs to the medium speed interval, determining the bit number of the bit code word when reporting by using the step size 2; when the moving speed belongs to the high-speed section, the bit number of the bit code word at the time of reporting is determined by using the larger step size 3.
4. Reporting period of beam measurement results.
Different moving speeds (intervals) correspond to different reporting periods. Alternatively, the faster the movement speed, the smaller the reporting period. When the moving speed of the terminal belongs to a low-speed interval, a larger reporting period 1 is used; when the moving speed belongs to the medium speed interval, a reporting period 2 is used; when the moving speed belongs to the high-speed section, a smaller reporting period 3 is used.
Step 304, beam management is performed according to the target beam management parameters.
And the terminal performs beam measurement according to the target beam management parameters, namely, performs measurement on reference signals corresponding to the beam, and obtains a beam measurement result. And the terminal reports the beam measurement result to the network equipment. And the network equipment determines a sending beam when sending downlink data according to the beam measurement result, and informs the terminal of the information of the sending beam.
The terminal determines its own reception beam according to the information of the transmission beam. And the terminal receives downlink data sent by the network equipment by adopting a receiving beam.
In summary, according to the method provided in the present embodiment, the target beam management parameter is determined in at least two sets of beam management parameters according to the moving speed of the terminal, and beam management is performed according to the target beam management parameter. The terminal can determine the target beam management parameters from at least two groups of beam management parameters by adopting smaller calculation amount, so that the realization logic is simpler. Because different mobile speeds can correspond to different beam management parameters, when the mobile speed of the terminal is high, reasonable beam management parameters can be adopted to reduce signaling overhead and reduce time delay.
A first possible implementation is described below using the embodiment of fig. 4:
fig. 4 shows a flowchart of a beam management method provided by another exemplary embodiment of the present disclosure. The method can be applied to the terminal shown in fig. 1, and the method comprises the following steps:
step 402, generating target beam management parameters according to the moving speed of the terminal and the basic beam management parameters.
The terminal determines a base beam management parameter, which is the basis for generating the sets of beam management parameters.
Optionally, the basic beam management parameter is built-in to the terminal, such as factory settings; in another design, the base beam management parameters are configured by the network device to the terminal.
In one design, the possible movement speeds of the terminal are divided into at least two movement speed intervals. Taking any two intervals of the moving speed interval as a first interval and a second interval as an example: when the moving speed belongs to a first interval, the terminal generates a first beam management parameter according to the basic beam management parameter and the first generation parameter, and the first beam management parameter is used as a target beam management parameter; and when the moving speed belongs to the second interval, the terminal generates a second beam management parameter according to the basic beam management parameter and the second generation parameter, and the second beam management parameter is used as a target beam management parameter.
Optionally, the first and second generation parameters are terminal-built, such as factory settings; in another design, the first and second generation parameters are configured by the network device to the terminal.
Depending on the content of the beam management parameters, exemplary implementations are as follows:
1. taking the example that the beam management parameters include a reference signal set: the network device configures a set of base reference signals to the terminal, the set of base reference signals comprising reference signals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
And when the moving speed of the terminal belongs to the low-speed interval, sampling according to the basic reference signal set and the sampling step length 1 to generate the reference signal set 1. The reference signal set 1 includes: reference signals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
And when the moving speed of the terminal belongs to the medium speed interval, sampling according to the basic reference signal set and the sampling step length 2 to generate the reference signal set 2. The reference signal set 2 includes: reference signals 0, 2, 4, 6, 8.
And when the moving speed of the terminal belongs to a high-speed interval, sampling according to the basic reference signal set and the sampling step length 3 to generate the reference signal set 3. The reference signal set 3 includes: reference signals 0, 3, 6, 9.
2. Taking the number of reported reference signals as an example, the beam management parameters include: the network device configures a basic upper limit 4 for the number of the terminals, where the upper limit refers to the limit of the number of the reported maximum reference signals when the terminals report the beam measurement results each time.
And when the moving speed of the terminal belongs to the low-speed interval, generating a first upper limit 4 according to the upper limit 4 of the basic number and the multiple 1. And when the moving speed of the terminal belongs to the medium speed interval, generating a second upper number limit 8 according to the upper number limit 4 and the multiple 2. When the moving speed of the terminal belongs to a high-speed section, a third upper limit 16 is generated according to the upper limit 4 of the basic number and the multiple 4.
Or when the moving speed of the terminal belongs to the low-speed interval, generating a first upper limit 4 according to the upper limit 4 of the basic number and the multiple 1. And when the moving speed of the terminal belongs to the medium speed interval, generating a second upper limit 2 according to the upper limit 4 of the basic number and the multiple 1/2. And when the moving speed of the terminal belongs to a high-speed interval, generating a third upper limit 1 according to the upper limit 4 of the basic number and the multiple 1/4.
3. Taking the example that the beam management parameters include the number of bits of the measurement value reported by the beam measurement result:
the network device configures the base reference step size 1 to the terminal.
For example, when the moving speed belongs to a medium speed interval, determining that the number of bits of a bit code word is 7 bits when reporting the measured value of the reference signal with the highest L1 level cell reference signal receiving intensity (L1-Reference signal received power, L1-RSRP) by using a first generation parameter 1, and the number of bits of the bit code word is 4 bits when reporting the difference between the measured value of other reference signals and the highest value; when the moving speed belongs to a high-speed interval, the second generation parameter 2 is used for determining that the bit number of the bit code word when reporting the measured value of the reference signal with the highest L1-RSRP is 7 bits or 4 bits, and the bit number of the bit code word when reporting the difference value between the measured value of other reference signals and the highest value is 4 bits or 2 bits.
4. Reporting period of beam measurement results.
Different moving speeds (intervals) correspond to different reporting periods. Alternatively, the faster the movement speed, the smaller the reporting period. The network device reports the period X to the terminal configuration base.
When the moving speed of the terminal belongs to a low-speed interval, a reporting period 2X is obtained by using a larger first generating parameter 2; when the moving speed belongs to the medium speed interval, the reporting period X is obtained by using the second generating parameter 1; when the moving speed belongs to the high-speed interval, the reporting period is 0.5X by using the third generation parameter 0.5.
Step 404, beam management is performed according to the target beam management parameters.
And the terminal performs beam measurement according to the target beam management parameters, namely, performs measurement on reference signals corresponding to the beam, and obtains a beam measurement result. And the terminal reports the beam measurement result to the network equipment. And the network equipment determines a sending beam when sending downlink data according to the beam measurement result, and informs the terminal of the information of the sending beam.
The terminal determines its own reception beam according to the information of the transmission beam. And the terminal receives downlink data sent by the network equipment by adopting a receiving beam.
In summary, the method provided in this embodiment generates the target beam management parameter according to the moving speed of the terminal and the basic beam management parameter. Because the network device only needs to configure the basic beam management parameters and at least two generation parameters to the terminal, smaller signaling overhead can be adopted, and the terminal can determine the target beam management parameters according to the moving speed of the terminal and the basic beam management parameters, so that the signaling overhead and the time delay are reduced as much as possible.
