Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a beam scanning method provided in an embodiment of the present invention, where the beam scanning method of the present embodiment is used in a network side device, as shown in fig. 1, and includes the following steps:
And 102, receiving a beam measurement report which is sent by the mobile communication terminal and corresponds to the beam management reference signal.
And 103, selecting a target beam scanning parameter group for beam alignment operation from at least two beam scanning parameter groups according to the beam measurement report.
And 104, sending an indication message indicating the target beam scanning parameter group to the mobile communication terminal, so that the mobile communication terminal can perform scanning operation according to the beam scanning parameters in the target beam scanning parameter group.
In the embodiment of the present invention, by receiving the beam measurement report corresponding to the beam management reference signal, a target beam scanning parameter set for a beam alignment operation may be determined according to the beam measurement report. Therefore, the indication message indicating the target beam scanning parameter group can be sent to the mobile communication terminal, so that the mobile communication terminal can determine a better beam alignment direction according to the period information, the frequency band information, the transmission angle information or the transmission power information in the target beam scanning parameter group, the mobile communication terminal can better receive signals sent by the network side equipment, and the network side equipment and the mobile communication terminal can better interact with each other.
In the embodiment of the invention, the beam management reference signal needs to be transmitted, and then the selection of the beam scanning parameter group is carried out based on the beam measurement report of the mobile communication terminal corresponding to the beam management reference signal. The beam management reference signal may be a beam management reference signal broadcast in each direction, or may be a beam management reference signal transmitted to a certain area, and the beam management reference signal may be continuously transmitted at a set period.
In the embodiment of the present invention, the beam measurement report corresponding to the beam management reference signal and sent by the mobile communication terminal is received, and the beam measurement report may include information such as the strength of the received signal and the angle of the received signal of the mobile communication terminal. Thus, when receiving the beam measurement report, the network side device can estimate the position of the mobile communication terminal, the motion information of the mobile communication terminal and the like according to the information included in the beam measurement report. The motion information may include information such as a speed of the mobile communication terminal and a motion direction of the mobile communication terminal. The network side equipment originally sends the beam management reference signal, and the mobile communication terminal originally uploads the beam measurement report to the network side equipment when receiving the beam management reference signal, so that the motion information of the mobile communication terminal can be monitored in real time without sending extra signals. In addition, the motion information of the mobile communication terminal can be rapidly acquired in the mode, the mobile communication terminal does not need to actively report the motion information of the mobile communication terminal, and certain expenses can be saved for both the network side equipment and the mobile communication terminal.
In an embodiment of the present invention, the selecting, according to the beam measurement report, a target beam scanning parameter set for beam alignment operation from at least two beam scanning parameter sets may be that a mapping relationship between a selection parameter and a beam scanning parameter set is preset, some selection parameters are determined through the beam measurement report, and the target beam scanning parameter set corresponding to the selection parameter determined by the beam measurement report is searched according to the mapping relationship; or it may be that some calculation is performed based on the beam measurement report, the target beam scanning parameter set is determined based on the result of the calculation, and so on. The target beam scanning parameter set may include beam period information, frequency band information, transmission angle information, transmission power information, and the like.
For example, the two rings in beijing may be very blocked in daytime, the operation speed of the mobile communication terminals used by the user in each vehicle may be very slow, and the network side device may use a beam with a relatively narrow range to satisfy the interaction with the mobile communication terminals. However, after 12 o' clock at night, the two rings of Beijing may become relatively smooth, so that the vehicle may run smoothly without jamming, the running speed of the mobile communication terminal may be greatly increased, and relatively large displacement may be generated in a relatively short time. If the network side device further adopts a beam with a narrow range at this time, the movement distance of the mobile communication terminal in a certain period may not be covered, and a beam with a wide range may need to be replaced to perform better interaction with the mobile communication terminal. For better understanding of the wider beam and the narrower beam, we can refer to fig. 2, where fig. 2 is a schematic diagram of a beam scanning method. It can be seen that a represents a relatively narrow range of beams and B represents a relatively wide range of beams.
In the prior art, after determining the configuration related to signal transmission with the mobile communication terminal, the network side device basically uses the fixed configuration for transmission, so that the real-time motion state of the mobile communication terminal is ignored. After the network-side device and the mobile communication terminal perform beam alignment, the mobile communication terminal may also generate a relatively large displacement at a relatively large speed, so that using the inherent beam scanning scheme may not be a good scheme, and a signal may not be covered by the mobile communication terminal or a covered signal may be relatively weak, thereby affecting interaction between the network-side device and the mobile communication terminal. The method can receive the beam measurement report of the mobile communication terminal, thereby estimating the motion information of the mobile communication terminal according to the beam measurement report, adjusting the transmission of the beam in real time and leading the mobile communication terminal and the network side equipment to be better interacted.
In the embodiment of the present invention, the Mobile communication terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
Optionally, selecting a target beam scanning parameter set for beam alignment operation from at least two beam scanning parameter sets according to the beam measurement report specifically includes:
determining a scanning selection parameter of the mobile communication terminal according to the beam measurement report in a predetermined time period, wherein the scanning selection parameter is as follows: motion information and/or location information and/or distribution probability information of the mobile communication terminal;
and selecting the target beam scanning parameter group according to the mapping relation between the scanning selection parameters and the beam scanning parameter groups which are stored in advance.
In this embodiment, the motion information may include information such as a rate of motion and a direction of motion of the mobile communication terminal; the location information may be used to indicate a location of the mobile communication terminal; the distribution probability information may indicate an area where the mobile communication terminal is most likely to appear, an area where the mobile communication terminal is less likely to appear, and the like. The mapping relationship may be a mapping relationship directly established from the history data of the scanning selection parameter and the beam scanning parameter set, or may be a mapping relationship established by theoretically calculating these parameters.
When the operation speed of the mobile communication terminal is relatively low, the requirement for the period of the network side device for transmitting the beam management reference signal may not be very high, that is, the period may be relatively long. However, when the operation speed of the mobile communication terminal is relatively high, the position of the mobile communication terminal generally changes greatly, and if it may be not appropriate for the network-side device to transmit the beam management reference signal in a relatively long period, the transmission period of the beam management reference signal needs to be shortened, for example, the period may be 10 milliseconds, 20 milliseconds, or another relatively short period defined.
Of course, in the above process, in order to grasp the state of the mobile communication terminal moving at a high speed in real time, the network side device is also required to send the beam management reference signal in a shorter period, so that the network side device can make dynamic adjustment according to the real-time state of the mobile communication terminal, better interaction between the network side device and the mobile communication terminal is enabled, and the flexibility of the network side device is improved.
Optionally, selecting the target beam scanning parameter group according to a mapping relationship between a prestored scanning selection parameter and a prestored beam scanning parameter group specifically includes:
optimizing the mapping relation according to the scanning selection parameters of the mobile communication terminal;
and selecting the target beam scanning parameter group according to the optimized mapping relation.
In the present embodiment, the mapping relationship may be a preset mapping relationship. However, when the scanning selection parameters of the mobile communication terminal are input, the mapping relationship can be optimized, and the re-output result is the result obtained according to the optimized mapping relationship, so that compared with a fixed preset relationship, the mapping relationship which can be adjusted and optimized has stronger adaptability, and different adjustments can be made according to different inputs. For example, the neural network model is a mapping relation which can be learned by self, and the model, namely the mapping relation, can be optimized by self in different input processes, so that the intelligent degree and flexibility of network side equipment can be improved, and better adjustment can be made under some uncertain states to obtain the mapping relation which is more in line with the existing condition.
Optionally, selecting a target beam scanning parameter set for beam alignment operation from at least two beam scanning parameter sets according to the beam measurement report specifically includes:
determining a scanning selection parameter of the mobile communication terminal according to the beam measurement report in a predetermined time period, wherein the scanning selection parameter is as follows: motion information and/or location information and/or distribution probability information of the mobile communication terminal;
calculating a beam scanning performance evaluation result corresponding to each beam scanning parameter group in the at least two beam scanning parameter groups according to the scanning selection parameters;
selecting the target beam scanning parameter group from at least two beam scanning parameter groups according to the beam scanning performance evaluation result.
In this embodiment, the motion information may include information such as a rate of motion and a direction of motion of the mobile communication terminal; the location information may be used to indicate a location of the mobile communication terminal; the distribution probability information may indicate an area where the mobile communication terminal is most likely to appear, an area where the mobile communication terminal is less likely to appear, and the like. The parameters in the beam scanning parameter set may include period information, signal transmission angle information, or transmission power information, etc. The above-mentioned calculating the beam scanning performance evaluation result corresponding to each of the at least two beam scanning parameter sets according to the scanning selection parameter may be a scanning performance evaluation result calculated by using a structural equation, or may also be a scanning performance evaluation result calculated by using deep learning. The scanning performance evaluation node can be directly embodied in one numerical value, and can also be represented by different numerical values in different ranges, for example, by using "excellent", "good", "medium", or "poor" and the like. Selecting the target beam scanning parameter group from at least two beam scanning parameter groups according to the beam scanning performance evaluation result, wherein the beam scanning parameter group corresponding to the beam scanning performance evaluation result with the largest value can be selected as the target beam scanning parameter group; alternatively, the beam sweep parameter group corresponding to the beam sweep performance evaluation result evaluated as "good" may be selected as the target beam sweep parameter group. Of course, more models may be used for evaluation, and this embodiment is not limited thereto.
Therefore, different beam scanning performance evaluation results can be evaluated, so that a target beam scanning parameter group which is relatively in line with the real-time requirement of the mobile communication terminal is determined, and the network side equipment and the mobile communication terminal can interact better.
Optionally, the method further includes:
transmitting the at least two beam scanning parameter sets and index information of each of the at least two beam scanning parameter sets to the mobile communication terminal;
the sending of the indication message indicating the target beam scanning parameter group specifically includes:
and transmitting the index information of the target beam scanning parameter group to the mobile communication terminal.
In this embodiment, the beam scanning parameter set may include beam period information, frequency band information, transmission angle information, transmission power information, and the like. The above index information may be "1", "2", "3", and "4", etc., or may also be "a", "B", "C", and "D", etc. For example: the index information 1 may correspond to the beam scanning parameter group 1, and the beam scanning parameter group 1 may include period information 1, frequency band information 1, transmission angle information 1, or transmission power information 1, etc.; the index information 2 may correspond to the beam scanning parameter set 2, and the beam scanning parameter set 2 may include period information 2, frequency band information 2, transmission angle information 2, or transmission power information 2, etc. Therefore, after different beam scanning parameter sets and the respective corresponding index information are sent to the mobile communication terminal, only the index information needs to be sent to the mobile communication terminal subsequently, and the mobile communication terminal can search the corresponding beam scanning parameter set according to the index information. By means of sending the index, the expense of information sending of the network side equipment can be reduced.
For better understanding of the above process, we can refer to fig. 3, and fig. 3 is an interaction diagram of a network side device and a mobile communication terminal. First, the network side device transmits a beam management reference signal to the mobile communication terminal, and the mobile communication terminal receives the signal in a beam scanning manner to determine the beam alignment direction of the network side device and the mobile communication terminal. Secondly, the mobile communication terminal reports a beam measurement report, which may include N beams with higher reference signal received power. The network side device may select an optimal configuration from a preset beam configuration and reference signal period configuration set according to a beam measurement report uploaded by the mobile communication terminal, and certainly the measurement report may include information such as a location and a motion state of the user. Finally, the network side device may broadcast the optimally configured index information to the user. Therefore, the cost of the network side equipment is reduced, and the network side equipment can make a better strategy according to the real-time state of the mobile communication terminal, so that the network side equipment and the mobile communication terminal can have better interaction.
Optionally, the beam scanning parameters include at least one of the following parameters: a scan period and a beam pattern.
In this embodiment, the scanning period may be 10 milliseconds, 20 milliseconds, or one other period set by a user. The beam pattern may include the number of beams, angles between different beams, etc. Thus, after the scanning period and the beam pattern of the network side equipment are known, the mobile communication terminal can better interact with the network side equipment.
Optionally, the beam management reference signal is a signal sent by the network side device when the mobile communication terminal performs beam scanning.
In this embodiment, after the network side device further transmits the beam management reference signal, the mobile communication terminal may receive the beam management reference signal. And the mobile communication terminal performs beam scanning, so that a beam measurement report can be sent to the network side device. The network side equipment can estimate the motion information of the mobile communication terminal according to the beam measurement report, so that the beam management reference signal can be sent more specifically when being sent next time. For example, the network side device may transmit the beam management reference signal in a broadcast manner at the beginning, and after determining the motion state of the mobile communication terminal, the beam management reference signal may be transmitted to a certain area.
Of course, in addition to the above-mentioned method, when the network side device, for example, the base station, performs beam scanning, the mobile communication terminal does not necessarily need to perform beam scanning, and because the mobile communication terminal may be single-beam, the mobile communication terminal may receive the reference signal in the beam scanning manner when it is multi-beam. But when the mobile communication terminal is a single beam, it is also possible to repeat reception with one beam.
Referring to fig. 4, fig. 4 is a flowchart of a beam scanning method provided in an embodiment of the present invention, where the beam scanning method is used in a mobile communication terminal, as shown in fig. 4, and includes the following steps:
and 404, interacting with a network side device according to the beam scanning parameters in the target beam scanning parameter group, and performing scanning operation.
In the embodiment of the present invention, the beam management reference signal sent by the network side device may be a beam management reference signal sent at a set period. The signal may be a beam management reference signal broadcast by the network side device in each direction, or may be a beam management reference signal transmitted to a certain area. The beam measurement report may include position information or velocity information of the mobile communication terminal, and the like. Of course, the speed information herein may not only represent the moving speed of the mobile communication terminal, but also include the moving direction of the mobile communication terminal. The target beam scanning parameter set may include beam period information, frequency band information, transmission angle information, transmission power information, and the like. After receiving the target beam scanning parameter set, the mobile communication terminal may determine a better beam alignment direction according to the period information, the frequency band information, the transmission angle information, or the transmission power information in the target beam scanning parameter set, so that the mobile communication terminal may better receive a signal sent by the network side device, and the mobile communication terminal may better interact with the network side device.
Optionally, the method further includes:
receiving the at least two beam scanning parameter groups and index information of the at least two beam scanning parameter groups sent by the network side equipment;
the receiving of the indication message indicating the target beam scanning parameter group sent by the network side device specifically includes:
and receiving the index information of the target beam scanning parameter group sent by the network side equipment.
In the present embodiment, the index information may be "1", "2", "3", and "4", or the like, or may be "a", "B", "C", and "D", or the like. For example: the index information 1 may correspond to the beam scanning parameter group 1, and the beam scanning parameter group 1 may include period information 1, frequency band information 1, transmission angle information 1, or transmission power information 1, etc.; the index information 2 may correspond to the beam scanning parameter set 2, and the beam scanning parameter set 2 may include period information 2, frequency band information 2, transmission angle information 2, or transmission power information 2, etc. Thus, different index information is received, and the corresponding beam scanning parameter set can be searched according to the index information. The cost of information transmission by the network side equipment is reduced, and the mobile communication terminal can also quickly search the corresponding beam scanning parameter group according to the index information.
It should be noted that, this embodiment is taken as an implementation of the mobile communication terminal corresponding to the embodiment shown in fig. 1, and specific implementation thereof may refer to the relevant description of the embodiment shown in fig. 1, so that, in order to avoid repeated description, the embodiment is not described again, and the same beneficial effects may also be achieved.
