Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
Fig. 1 shows a block diagram of a communication system provided by an exemplary embodiment of the present disclosure, which includes an access network 12 and a terminal 14.
The terminal 14 may include various handheld devices, vehicle mounted devices, computing devices or other processing devices connected to wireless modems, as well as various forms of user equipment, Mobile Stations (MSs), terminals (terminal devices), and the like, having wireless communication capabilities. For convenience of description, the above-mentioned devices are collectively referred to as a terminal. The access network device 120 and the terminal 14 communicate with each other via some air interface technology, such as a Uu interface.
In the communication of the internet of vehicles, the network Device and the terminal may be one of the vehicle-mounted devices, and the communication between the network Device and the terminal may be direct communication between the vehicle-mounted devices through D2D (Device to Device).
Fig. 2 shows a flowchart of a beam management method according to an exemplary embodiment of the present disclosure. The method can be applied to the terminal shown in fig. 1, and comprises the following steps:
since the terminal is a mobile terminal, it is carried by the user to any possible place. Optionally, the terminal obtains its own moving speed through a built-in sensor. Built-in sensors include, but are not limited to: a global positioning chip, an acceleration sensor, or a six-axis acceleration sensor. In this embodiment, how the terminal obtains its own moving speed is not limited, and other possible manners such as a triangulation method based on a base station, a triangulation method based on a terminal in an internet of vehicles, and the like may also be used.
And the terminal determines different beam management parameters according to different moving speeds. Optionally, at least two moving speed intervals are set, and different moving speed intervals correspond to different beam management parameters.
In one example, the at least two movement speed intervals include: a medium speed (medium speed) section and a high speed (high speed) section. When the moving speed of the terminal belongs to a medium-speed interval, adopting a beam management parameter corresponding to the medium-speed interval; and when the moving speed of the terminal belongs to the high-speed interval, adopting the beam management parameters corresponding to the high-speed interval.
In one example, the at least two movement 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 a beam management parameter corresponding to the low-speed interval; when the moving speed of the terminal belongs to a medium-speed interval, adopting a beam management parameter corresponding to the medium-speed interval; and when the moving speed of the terminal belongs to the high-speed interval, adopting the beam management parameters corresponding to the high-speed interval.
It should be noted that the terminal moving speed considered here may be an absolute moving speed of the terminal, for example, when the network device is stationary, the moving speed of the terminal is the absolute moving speed of the terminal; the moving speed of the terminal can also be a relative moving speed of the terminal, for example, when the vehicle-mounted device is in vehicle networking communication, the two vehicle-mounted devices may be moving, 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:
1. a reference signal or set of reference signals 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 bit number of the measurement value reported in the beam measurement result;
the measurement values need to be reported in the beam measurement results. The measured values are represented by bit code words of n bits. The bit overhead for different bit numbers is different. By reducing the bit number occupied by reporting the measured value of each reference signal, the signaling overhead can be reduced.
4. And reporting period of the beam measurement result.
Different moving speeds (intervals) correspond to different reporting periods. Optionally, the faster the moving speed, the smaller the reporting period.
And step 204, performing beam management according to the target beam management parameters.
And the terminal measures the beams according to the target beam management parameters, namely measures the reference signals corresponding to the beams to obtain a beam measurement result. And the terminal reports the beam measurement result to the network equipment. And the network equipment determines a transmission beam when transmitting the downlink data according to the beam measurement result, and informs the terminal of the information of the transmission beam.
And the terminal determines the receiving beam of the terminal according to the information of the transmitting beam. And the terminal receives downlink data sent by the network equipment by adopting the receiving wave beam.
In summary, in the method provided in this 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 moving speeds can correspond to different beam management parameters, when the moving speed of the terminal is higher, the reasonable beam management parameters can be adopted to reduce signaling overhead and delay.
There are two different implementations of the above step 202:
a first possible implementation: and determining a target beam management parameter from the multiple groups of beam management parameters according to the moving speed of the terminal.
A second possible implementation: a group of basic beam management parameters exist, and target beam management parameters are generated on the basis of the basic beam management parameters according to the moving speed of the terminal.
A first possible implementation is described below with the embodiment of fig. 3:
fig. 3 shows a flowchart of a beam management method according to another exemplary embodiment of the present disclosure. The method can be applied to the terminal shown in fig. 1, and comprises the following steps:
the terminal determines at least two groups of beam management parameters, and each group of beam management parameters corresponds to a respective moving speed (or moving speed interval). Table one exemplarily shows a correspondence between the moving speed interval and the beam management parameter.
Watch 1
Wherein, 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 built-in to the terminal, 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 the multiple sets 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 the at least two groups of beam management parameters as a target beam management parameter.
Depending on the content of the beam management parameters, an exemplary implementation is as follows:
1. take the beam management parameters including the reference signal set as an example: 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, using a reference signal set 1; when the moving speed belongs to the middle-speed interval, using a reference signal set 2; when the moving speed belongs to the high speed section, the reference signal set 3 is used. For example, the moving speed may be further subdivided, so that more reference signal sets for different moving speed intervals are required. Such as: for each reference signal corresponding to a higher moving speed, the beam used by the network device in transmission is wider, and the number of reference signals in the beam reference signal set corresponding to the higher moving speed is smaller.
2. Taking the beam management parameters including the number of reported reference signals as an example: the network equipment configures a plurality of number upper limits to the terminal, wherein the number upper limits refer to the maximum number limit of the reported reference signals when the terminal reports the beam measurement result every time. Different upper limits of the number correspond to different moving speed intervals. Optionally, the greater the moving speed, the greater the number of reference signals reported.
Optionally, the number upper limit includes: 1. 2, 4, 8 and 16. Exemplarily, when the moving speed of the terminal belongs to a low-speed interval, the upper limit of the number of the reference signals reported is 2; when the moving speed belongs to the middle-speed interval, the upper limit of the number of the reference signals is 4 when the reference signals are reported; when the moving speed belongs to a high-speed interval, the upper limit of the number of the reference signals reported is 16.
In another implementation, the greater the moving speed, the fewer the number of reference signals reported.
Optionally, the number upper limit includes: 1. 2, 4, 8 and 16. Exemplarily, when the moving speed of the terminal belongs to a low-speed interval, the upper limit of the number of the reference signals reported is 8; when the moving speed belongs to the middle-speed interval, the upper limit of the number of the reference signals is 4 when the reference signals are reported; when the moving speed belongs to a high-speed interval, the upper limit of the number of the reference signals reported is 2.
3. Taking the example that the beam management parameters include the bit number of the measurement value reported in the beam measurement result:
the measurement values need to be reported in the beam measurement results. The measured values are represented by bit code words of n bits. The bit overhead for different bit numbers is different. By reducing the number of bits occupied by reporting the measurement value of each reference signal, the signaling overhead can be reduced.
For example, the currently measured value of the reference signal with the highest L1-RSRP is represented by a bit codeword of 7 bits ([ -140, -44] dBm range, where each two adjacent bit codewords differ by 1dB, i.e., the step size between the two adjacent bit codewords is 1dB), and the measured values of the other reference signals are represented by a difference value from the highest value represented by 4 bits (each two adjacent bit codewords differ by 2dB, i.e., the step size between the two adjacent bit codewords is 2 dB). Then to reduce the signaling overhead, the step size between every two adjacent bit code words can be increased, e.g. the larger the speed, the larger the step size, and thus the number of bits can be reduced.
For example, when the moving speed belongs to a low speed interval, the terminal determines the bit number of the bit code word during reporting by using a smaller step size 1; when the moving speed belongs to a middle-speed interval, determining the bit number of the bit code word during reporting by using the step size 2; when the moving speed belongs to a high-speed interval, the larger step size 3 is used for determining the bit number of the bit code word in the reporting process.
4. And reporting period of the beam measurement result.
Different moving speeds (intervals) correspond to different reporting periods. Optionally, the faster the moving 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 middle-speed interval, using a reporting period 2; when the moving speed belongs to a high-speed interval, a smaller reporting period 3 is used.
And step 304, performing beam management according to the target beam management parameters.
And the terminal measures the beams according to the target beam management parameters, namely measures the reference signals corresponding to the beams to obtain a beam measurement result. And the terminal reports the beam measurement result to the network equipment. And the network equipment determines a transmission beam when transmitting the downlink data according to the beam measurement result, and informs the terminal of the information of the transmission beam.
And the terminal determines the receiving beam of the terminal according to the information of the transmitting beam. And the terminal receives downlink data sent by the network equipment by adopting the receiving wave beam.
In summary, in the method provided in this 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 the beam management is performed according to the target beam management parameter. The terminal can determine the target beam management parameter from at least two groups of beam management parameters by adopting smaller calculated amount, and the realization logic is simpler. Because different moving speeds can correspond to different beam management parameters, when the moving speed of the terminal is higher, the reasonable beam management parameters can be adopted to reduce signaling overhead and delay.
A first possible implementation is described below with the embodiment of fig. 4:
fig. 4 shows a flowchart of a beam management method according to another exemplary embodiment of the present disclosure. The method can be applied to the terminal shown in fig. 1, and comprises the following steps:
The terminal determines basic beam management parameters, which are the basis for generating the sets of beam management parameters.
Optionally, the basic beam management parameter is built in the terminal, such as factory setting; in another design, the base beam management parameter is 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 intervals 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 as a target beam management parameter according to the basic beam management parameter and the first generation parameter; and when the moving speed belongs to a second interval, the terminal generates a second beam management parameter as a target beam management parameter according to the basic beam management parameter and the second generation parameter.
Optionally, the first generation parameter and the second generation parameter are built in the terminal, such as factory settings; in another design, the first generation parameter and the second generation parameter are configured by the network device to the terminal.
Depending on the content of the beam management parameters, an exemplary implementation is as follows:
1. take the beam management parameters including the reference signal set as an example: the network equipment configures a basic reference signal set including reference signals 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 to the terminal.
And when the moving speed belongs to a low-speed interval, the terminal generates a reference signal set 1 in a sampling mode according to the basic reference signal set and the sampling step length 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 middle-speed interval, sampling to generate a reference signal set 2 according to the basic reference signal set and the sampling step length 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 to generate a reference signal set 3 according to the basic reference signal set and the sampling step length 3. The reference signal set 3 includes: reference signals 0, 3, 6, 9.
2. Taking the beam management parameters including the number of reported reference signals as an example: the network device configures a basic number upper limit 4 to the terminal, where the number upper limit refers to the maximum reference signal number limit reported when the terminal reports the beam measurement result each time.
And when the moving speed of the terminal belongs to a low-speed interval, generating a first number upper limit 4 according to the basic number upper limit 4 and the multiple 1. And when the moving speed of the terminal belongs to the middle-speed interval, generating a second number upper limit 8 according to the basic number upper limit 4 and the multiple 2. And when the moving speed of the terminal belongs to a high-speed interval, generating a third number upper limit 16 according to the basic number upper limit 4 and the multiple 4.
Or, when the moving speed belongs to the low-speed section, the terminal generates a first number upper limit 4 according to the basic number upper limit 4 and the multiple 1. And when the moving speed of the terminal belongs to the middle speed interval, generating a second upper limit 2 of the number 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 number 1 according to the upper limit number 4 and the multiple 1/4.
3. Taking the example that the beam management parameters include the bit number of the measurement value reported in the beam measurement result:
the network device configures a base reference step size 1 to the terminal.
For example, when the moving speed belongs to a medium-speed interval, using the first generation parameter 1 to determine that the bit number of the bit code word when reporting the measured value of the Reference signal with the highest L1-level cell Reference signal received strength (L1-Reference signal received power, L1-RSRP) is 7 bits, and the bit number of the bit code word when reporting the difference between the measured values of other Reference signals and the highest value is 4 bits; 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 the measured value of the reference signal with the highest L1-RSRP is reported is 7 bits or 4 bits, and the bit number of the bit code word when the difference value between the measured values of other reference signals and the highest value is reported is 4 bits or 2 bits.
4. And reporting period of the beam measurement result.
Different moving speeds (intervals) correspond to different reporting periods. Optionally, the faster the moving speed, the smaller the reporting period. And the network equipment configures a basic reporting period X to the terminal.
When the moving speed of the terminal belongs to a low-speed interval, a larger first generation parameter 2 is used to obtain a reporting period 2X; when the moving speed belongs to the medium-speed interval, obtaining a reporting period X by using a second generation parameter 1; and when the moving speed belongs to a high-speed interval, using a third generation parameter 0.5 to obtain a reporting period of 0.5X.
And the terminal measures the beams according to the target beam management parameters, namely measures the reference signals corresponding to the beams to obtain a beam measurement result. And the terminal reports the beam measurement result to the network equipment. And the network equipment determines a transmission beam when transmitting the downlink data according to the beam measurement result, and informs the terminal of the information of the transmission beam.
And the terminal determines the receiving beam of the terminal according to the information of the transmitting beam. And the terminal receives downlink data sent by the network equipment by adopting the receiving wave 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 equipment only needs to configure basic beam management parameters and at least two generation parameters to the terminal, the terminal can determine the target beam management parameters according to the moving speed of the terminal and the basic beam management parameters by adopting smaller signaling overhead, and the signaling overhead and the time delay are reduced as much as possible.
