Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 is a flow chart illustrating a cell parameter configuration method in a high-speed mobile scenario according to an embodiment of the present invention. The method is performed by a base station apparatus. The base station device is preferably a communication base station in 5G communication. As shown in fig. 1, the cell parameter configuration method in the high-speed mobile scenario includes:
step S11: and collecting channel measurement information reported by each terminal in the cell by two continuous channel measurements.
In the embodiment of the invention, the preset number of terminals are selected each time in a polling mode to perform channel measurement twice, and the preset time is measured each time; and collecting the channel measurement information of each measurement. For example, the base station selects 10 terminals for channel measurement by means of polling. The terminal measures in two measurements each of 2 seconds apart. And the terminal reports the channel measurement information obtained by each measurement to the base station. And the base station receives and records the channel measurement information reported by each measurement of each terminal. The base station selects different 10 terminals to carry out channel measurement in a periodical polling mode, and collects channel measurement information of the terminals, so that the environment change condition of the terminal links of the whole cell can be mastered.
Step S12: and acquiring the movement condition of each terminal according to the difference of the channel measurement information reported by the continuous two times of channel measurement of each terminal.
In the embodiment of the invention, after the base station collects the channel measurement information reported by the terminal in the cell, the base station reports the collected terminal channel measurement information of the cell to the network management platform. After the network management platform obtains the terminal channel measurement information of the cell, the terminal movement rate can be judged by comparing the difference of the two channel measurement information results reported by the same terminal, such as the change of SSB wave beams where the terminal is located, the difference of uplink RSRP and path loss, and the change of the weight of the terminal according to the difference of the two channel measurement information reported by the terminal.
If the difference of the channel measurement information reported by any terminal for two continuous channel measurements is larger, determining that the terminal movement rate is faster; otherwise, the slower the terminal movement speed. The channel measurement information at least comprises information such as synchronous signal block (Synchronization Signal and PBCH block, SSB) wave beam information, uplink reference signal received power (Reference Signal Receiving Power, RSRP), path loss, weight and the like. Specifically, if the SSB beam number continuously reported by any one of the terminals changes, or the absolute value of the result difference between the uplink RSRP and the uplink loss continuously reported by any one of the terminals exceeds a first threshold, or the phase difference of the weight continuously reported by any one of the terminals is greater than a second threshold, it is determined that the terminal moving speed is faster, and the terminal is a high-speed terminal. The first threshold and the second threshold may be set as needed. For example, if the number of the SSB beam changes twice reported by the interval 2S of one terminal, it indicates that the terminal moves fast. If the absolute value of the difference value of the two reporting results of the uplink RSRP and the uplink path loss of one terminal exceeds 10dB, the terminal moving speed is higher, and the signal fluctuation is large. If the phase difference of the two reported results of the weight of one terminal is larger than 30 degrees, the terminal moving speed is higher. The embodiment of the invention integrates the judgment of the three dimensions and can estimate the moving speed condition of the user corresponding to the terminal.
And carrying out similar statistical processing on the channel measurement information reported by all the polling terminals, and obtaining the moving speed condition of each polling terminal.
Step S13: and identifying the movement attribute of the cell according to the movement condition of each terminal, and configuring the channel parameters of the cell according to the movement attribute.
In the embodiment of the invention, the high-low speed duty ratio of all terminals polled in the cell is counted; and if the high-speed terminal duty ratio in the cell exceeds a third threshold value, determining that the cell belongs to a high-speed mobile cell. Wherein the third threshold may be set as desired. By counting the high-low speed duty cycle of all polling terminals in a cell, it can be decided whether the cell is mainly high-speed or mainly low-speed. For example, if the high-speed user ratio exceeds 60%, it is determined that the cell belongs to a high-speed mobile cell. Otherwise, the subsequent configuration is not performed.
In the embodiment of the invention, the channel measurement information reported by each terminal in the cell is collected every preset period, and the movement condition of each terminal is acquired according to the channel measurement information, so as to judge whether the cell moves at high speed. For example, the preset period is one week, that is, the channel condition reported by the terminal polling is collected once every week to make a decision, and the decision result is kept for one week.
After the network management platform of the base station calculates the judgment result of the cell moving speed type, the network management platform informs the configuration management platform of the base station of the judgment result of the cell moving speed type. After knowing the moving speed type of the cell, the configuration management platform needs to perform corresponding channel parameter configuration for the cell based on the high-medium-low speed moving speed type of the cell, namely, issuing corresponding SRS/TRS/CSI-RS extremely short period channel configuration parameters and Additional (Additional) DMRS configuration for the cell. The additional DMRS configuration is the subsequent preamble+auxiliary DMRS configuration. Configuration delivery requires periodic timing modifications as may involve cell reset.
In step S13, for the determined high-speed mobile cell, configuring the cell by using SRS/TRS/CSI-RS extremely short period, and configuring the SRS/TRS/CSI-RS extremely short period to be 10ms/5ms/5ms; and configuring a pilot channel of the cell by adopting the pre-arranged and auxiliary DMRS. As shown in fig. 2, adapting to a high-speed rail scene, the air interface channel changes faster, and the key pilot information includes: the TRS is used for accurate time-frequency tracking, the SRS is used for beam tracking, the CSI-RS is used for precoding matrix indication (Precoding Matrix Indicator, PMI)/Rank Indication (RI)/channel quality identification (Channel Quality Identity, CQI) measurement, and the SRS/TRS/CSI-RS extremely short periods are respectively configured to be 10ms/5ms/5ms, so that the downlink rate can be improved. As shown in fig. 3, adapting a high-speed scenario, supports flexible pre+auxiliary DMRS configuration: 1+0, 1+1, 1+2, 1+3 optimally configures pilot channels, increases the number of auxiliary DMRS pilot frequencies, is more suitable for a high-speed moving scene, and combines the improvement of uplink and downlink demodulation performance and the consumption of downlink resources, thereby improving the downlink rate.
The embodiment of the invention carries out channel measurement through the terminal, judges the moving speed characteristics of the 5G cell according to the reported channel measurement information, and adaptively configures the channel parameters matched with the moving speed of the cell, thereby realizing the optimal performance of the cell. The high-low speed cell adaptively configures channel parameters, so that the cell can play optimal performance in high-low speed scenes, can be automatically identified and configured, reduces operation and maintenance cost and improves parameter configuration accuracy.
The following description will be given by taking a case that a certain cell covers a highway scene as an example:
the base station selects 10 terminals each time through polling, and reports channel measurement information once at intervals of 2 s. After receiving the channel measurement instruction issued by the base station, the terminal performs channel measurement twice, and the interval between the two measurements is 2 s. And finishing channel measurement every time and reporting the SSB beam information to the base station, and carrying out channel measurement information such as uplink RSRP, path loss, weight and the like. The base station collects channel measurement information periodically reported by polling terminals, polls 10 terminals each time, and presumes 100 terminals in the cell, the base station can acquire the channel measurement information of all terminals in the cell after polling for 10 times, and the base station collects the channel measurement information of all terminals and uploads the channel measurement information to the network management platform.
And the network management platform receives channel measurement information of all terminals reported by the base station, and judges the movement condition of each terminal by judging the SSB wave beam information of each terminal, and the changes of the uplink RSRP, the path loss and the weight. If there are 65 terminals among 100 terminals belonging to the high-speed terminal, 25 terminals are medium-speed terminals, and 10 terminals belong to the low-speed terminal. The high speed terminal is 65% and the cell is determined to be a high speed mobile cell.
The network management platform informs the mobile attribute of the cell to the configuration management platform, and the configuration management platform selects the corresponding optimal channel configuration relation according to the terminal mobile rate judged in advance and sends the optimal channel configuration relation to the cell. The general moving speed of a high-speed moving cell is more than 120KM/h, the corresponding optimal SRS/TRS/CSI-RS period under the speed is (10 ms/5ms/5 ms), the pre-set and auxiliary DMRS is configured to be 1+1, the improvement of demodulation performance and the consumption of downlink resources are balanced, and the optimal downlink speed is achieved, and the parameter configuration is issued to the cell. After the optimal channel period of the cell is configured, the method is more suitable for the air interface channel change of the terminal under the cell, which is changed at high speed, so that the uplink and downlink experience rate of the user is improved.
The embodiment of the invention collects the channel measurement information reported by two continuous channel measurements of each terminal in the cell; acquiring the movement condition of each terminal according to the difference of the channel measurement information reported by each terminal in two continuous channel measurements; and identifying the movement attribute of the cell according to the movement condition of each terminal, and configuring the channel parameters of the cell according to the movement attribute, so that the channel parameters matched with the movement rate of the cell can be configured in a self-adaptive manner, the uplink and downlink experience rate of a user is improved, and the optimal performance of the cell is realized.
