Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in each embodiment of the application, many technical details are provided for readers to better understand the application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can also be realized. The division of the following embodiments is for the convenience of description, and should not constitute any limitation to the specific implementation of the present application, and the embodiments can be combined and referred to each other on the premise of no contradiction.

The method for improving the downlink quality of voice services in this application is applicable to 4G, 5G, and 6G networks, and can implement VoLTE voice or VoNR voice in weak downlink coverage scenarios or strong downlink interference scenarios, through PDSCH ( Physical Downlink Shared channel, physical downlink shared channel) plus power, and/or, add power to the PDCCH (Physical Downlink Control channel, physical downlink control channel) of the voice service of the target user equipment, so as to significantly improve the voice downlink call quality.

The embodiment of the present application relates to a method for improving the downlink quality of a voice service, as shown in FIG. 1 , including:

Step 101, in response to the first instruction, judge whether there is surplus power in the physical downlink shared channel PDSCH of the cell where the target user equipment UE is located, and the target UE is a UE processing a voice service.

In this embodiment, the voice service is a voice service in a 4G network, a 5G network or a 6G network. The remaining power may be the entire downlink available power, or the downlink available power corresponding to the voice service. Of course, if power sharing is enabled in a cell, the remaining power also includes available power shared by other cells. In addition, the PDSCH is one of the LTE physical downlink channels, and is a downlink channel for LTE to carry main user data, and all user data can be used.

In an embodiment, before step 101, it also includes: detecting the current block error rate of the PDSCH of the voice service of the target UE, where the current block error rate of the PDSCH is higher than the first target block error rate and the modulation and coding strategy of the target UE When the MCS value is a preset lower limit value of MCS, a first instruction is generated.

It should be noted that the block error rate refers to the percentage of erroneous blocks in all transmitted blocks. For example, the block error rate of a data channel in LTE is required to be 10%. In addition, the configuration of the rate in LTE can be realized through the MCS (Modulation and Coding Scheme, modulation and coding strategy) index value. MCS regards the factors that affect the communication rate as the column of the table, and uses the MCS index as the row to form a rate surface. Therefore, each MCS index actually corresponds to the physical transmission rate under a set of parameters. The MCS value mentioned in this embodiment is the MCS index value. In addition, the method for improving the downlink quality of voice services provided by this application is only for QPSK modulation or lower-order modulation than QPSK, and each MCS index value in the rate table has a corresponding modulation method. Therefore, the preset MCS The lower limit value can be set accordingly.

In another embodiment, when the current block error rate of the PDSCH is higher than the first target block error rate and the MCS value of the target UE is the lower limit value of the MCS, and before the first instruction is generated, further Including: updating the first target block error rate, wherein the updated first target block error rate is higher than the first target block error rate before updating; re-detecting the current block error rate of the PDSCH of the target UE, and the re-detected PDSCH The current block error rate is higher than the updated first target block error rate.

It can be understood that when the block error rate of the PDSCH of the voice service of the target UE is higher than the first target block error rate and the modulation and coding strategy MCS value of the target UE is a preset lower limit value of MCS, the present application further improves the first target block error rate. A target block error rate, that is, to update the first target block error rate so that the updated first target block error rate is higher than the first target block error rate before updating, that is to say, through this step, the error rate in service transmission is improved. The block tolerance, which allows for a slight degradation in speech quality. After updating the first target block error rate, detect the current block error rate of the PDSCH of the target UE again, and when the current block error rate of the re-detected PDSCH is higher than the updated first target block error rate, trigger the generation of the first instruction Perform power up operation to improve voice downlink performance.

Step 102: If there is residual power in the PDSCH of the cell where the target UE is located, power is added to the PDSCH of the voice service of the target UE based on the residual power.

In an embodiment, step 102 is specifically, adding power to the PDSCH of the voice service of the target UE based on the remaining power and the first preset power adding step. After adding power to the PDSCH of the voice service of the target UE based on the remaining power and the preset first power-up step size, re-detect the current block error rate of the PDSCH; and the re-detected current block error rate of the PDSCH is higher than the updated first In the case of a target block error rate, a first instruction is generated. For example: the first power increase step is set to 1db, that is, the power is increased by 1db each time.

In an embodiment, step 102 is specifically: if there is residual power in the PDSCH of the cell where the target UE is located and the current power of the PDSCH of the voice service of the target UE has not yet reached the reference power of the PDSCH of the voice service of the target UE, based on the remaining power and the reference power is PDSCH plus power for voice services of the target UE.

It should be noted that the PDSCH of each UE's voice service has a reference power, which represents the upper limit of the added power of the PDSCH of the UE's voice service. Once the power of the PDSCH of the UE's voice service exceeds the reference power, power cannot be added For specific operations, you can define your own settings according to application scenarios and business requirements.

Step 103: If there is no remaining power in the PDSCH of the cell where the target UE is located, reduce the number of resource blocks occupied by the PDSCH of the voice service of the target UE, and increase the power of the PDSCH of the voice service of the target UE based on the power occupied by the reduced resource blocks.

In an embodiment, reducing the number of resource blocks occupied by the PDSCH of the voice service of the target UE includes one or any combination of the following methods: if the discontinuous reception DRX function of the target UE is turned on, turn off the DRX function of the target UE ; If the downlink coding rate of the target UE has not reached the preset rate lower limit value, reduce the downlink coding rate of the target UE; if the downlink voice packet of the target UE has not been fragmented, fragment the downlink voice packet.

Specifically, when the DRX (Discontinuous Reception, Discontinuous Reception) function is enabled, the number of resource blocks consumed may double, affecting the effect of power addition. For example, when the DRX function is turned off, one VoLTE voice packet may be scheduled every 20ms; when the DRX function is turned on, it becomes two VoLTE voice packets every 40ms, consuming doubled resource blocks. In addition, the downlink coding rate of the target UE can be decelerated to better exert the effect of power addition, especially for small bandwidth scenarios. For example, you can set the lower limit of the rate to AMR-WB6.6K. If the downlink encoding rate is AMR-WB23.85K at this time, and the lower limit of the rate has not yet been reached, you can reduce the downlink encoding rate of the target UE at this time. Therefore, the speed can be reduced to AMR-WB12.65K, or it can be directly reduced to the lower limit value of AMR-WB6.6K. Of course, this is only a specific example, and the setting of the specific lower limit value of the rate and the step size of the speed reduction can be adjusted according to the application scenario and the quality improvement requirements. In addition, fragmenting the voice packet refers to fragmenting a VoLTE voice packet, so that each fragment occupies fewer resource blocks RB, and further improves the effect of PDSCH power addition. In one embodiment, a maximum of 2 slices is suggested. It is worth noting that fragmenting voice packets is mainly used in small bandwidth scenarios.

It should be noted that an optional way to reduce the number of resource blocks occupied by the PDSCH of the voice service of the target UE is: if the DRX function of the target UE is enabled, then turn off the DRX function of the target UE; if the DRX function of the target UE If it is off and the downlink coding rate of the target UE has not reached the preset rate lower limit, reduce the downlink coding rate of the target UE; if the DRX function of the target UE is off and the downlink coding rate of the target UE has reached the lower limit of the rate value and the downlink voice packet has not been fragmented, fragment the downlink voice packet.

In an embodiment, step 103 is specifically: adding power to the PDSCH of the voice service of the target UE based on the reduced power occupied by the resource blocks and the first power adding step. After adding power to the PDSCH of the voice service of the target UE, it is necessary to re-detect the current block error rate of the PDSCH; and when the re-detected current block error rate of the PDSCH is higher than the updated first target block error rate, generate the first instruction.

In addition, in order to further ensure the effect of adding power, the present application also includes: in response to the first instruction, sending a request to suspend the use of the target time-frequency resource to the neighboring cell of the cell; wherein, the target time-frequency resource refers to the current use of the voice service of the target UE time-frequency resources. In this way, the downlink quality of the voice service of the target UE can be fully guaranteed to be improved by suspending the use of the target time-frequency resource by the neighboring cells of the cell where the target UE is located.

The embodiment of the present application relates to a method for improving the downlink quality of a voice service, as shown in FIG. 2 , including:

Step 201, in response to the first instruction, judge whether there is surplus power in the physical downlink shared channel PDSCH of the cell where the target user equipment UE is located, and the target UE is a UE processing a voice service.

Step 202: If there is residual power in the PDSCH of the cell where the target UE is located, power is added to the PDSCH of the voice service of the target UE based on the residual power.

Step 203: If there is no remaining power in the PDSCH of the cell where the target UE is located, reduce the number of resource blocks occupied by the PDSCH of the voice service of the target UE, and increase the power of the PDSCH of the voice service of the target UE based on the power occupied by the reduced resource blocks.

In this embodiment, the specific implementation details of steps 201 - 203 are basically the same as those of steps 101 - 103 , and will not be repeated here.

Step 204, in response to the second instruction, determine a way to reduce power for the PDSCH of the target UE according to the way to increase power for the PDSCH of the voice service of the target UE.

In an embodiment, before step 204, it also includes: re-detecting the current block error rate of the PDSCH of the voice service of the target UE, and when the current block error rate of the re-detected PDSCH is lower than the preset first target block error rate case, a second instruction is generated.

It can be understood that after powering up the PDSCH of the voice service of the target UE, the current block error rate of the PDSCH of the voice service of the target UE needs to be re-detected. Once the current block error rate is lower than the preset first target block error rate rate, it indicates that the downlink quality of the current voice service is good and has been improved. Based on this, a second instruction is generated to trigger a power reduction operation. The method for reducing the power of the PDSCH of the voice service of the target UE is to control the operation according to the method of increasing the power of the PDSCH of the voice service of the target UE. It should be noted that the first target block error rate at this time may be an updated first target block error rate.

Step 205: Reduce the power of the PDSCH of the voice service of the target UE according to the determined power reduction method, wherein the method of adding power to the PDSCH of the voice service of the target UE is: based on the remaining power, the PDSCH of the voice service of the target UE Adding power to the PDSCH, or reducing the number of resource blocks occupied by the PDSCH of the voice service of the target UE, and adding power to the PDSCH of the voice service of the target UE based on the power occupied by the reduced resource blocks.

In this embodiment, step 205 specifically includes: reducing the power of the PDSCH of the voice service of the target UE according to the determined power reduction method and the preset first power reduction step size. After reducing the power of the PDSCH of the voice service of the target UE, it is necessary to re-detect the current block error rate of the PDSCH of the UE voice service; and when the current block error rate of the re-detected PDSCH is lower than the preset first target block error rate Next, generate a second instruction.

It should be noted that, similar to the process of adding power, when power is reduced, the current block error rate of the PDSCH of the voice service of the UE needs to be re-detected every time the power is reduced for the PDSCH of the voice service of the target UE. If the current block error rate is higher than the preset first target block error rate, it indicates that the downlink voice service quality is poor at this time, and the power increase operation is performed; if the current block error rate is lower than the preset first target block error rate rate, indicating that the quality of the downlink voice service is improved at this time, and the power reduction operation is performed. Certainly, the first target block error rate at this time may be an updated first target block error rate.

In an embodiment, the method for determining the PDSCH power reduction of the voice service of the target UE includes one or any combination of the following methods: if the downlink voice packet of the target UE has been fragmented, fragment the downlink voice packet Merge; if the downlink coding rate of the target UE has not reached the preset rate upper limit, increase the downlink coding rate of the target UE; if the DRX function of the target UE is disabled, enable the DRX function of the target UE.

Specifically, merging voice packets into fragments, increasing the downlink coding rate, and enabling the DRX function are all reverse-controlled operations from disabling the DRX function, reducing the downlink coding rate, and fragmenting voice packets during the power-up process. .

It should be noted that the optional way to reduce the power of the PDSCH determined to be the voice service of the target UE is: if the downlink voice packet of the target UE has been fragmented, then merge the fragments of the downlink voice packet; If the downlink coding rate of the target UE has not been fragmented and the downlink coding rate of the target UE has not reached the rate limit, increase the downlink coding rate of the target UE; if the downlink voice packet of the target UE is not fragmented, the downlink coding rate of the target UE has reached the rate limit value and the DRX function of the target UE is disabled, then enable the DRX function of the target UE.

This application proposes a method for improving the downlink quality of voice services. When there is surplus power in the physical downlink shared channel PDSCH of the cell where the target user equipment UE is located, power is added to the PDSCH based on the surplus power. When there is no surplus power, by reducing The number of resource blocks occupied by the PDSCH of the voice service of the target UE is the power of the PDSCH. In this way, the downlink quality of the voice service can be significantly improved by adding power. When the downlink quality of the voice service is improved, the PDSCH power is reduced in the opposite direction according to the PDSCH power increase method of the voice service of the target UE. In this way, the remaining power of the PDSCH in the cell where the target UE is located can be fully utilized, avoiding waste.

The embodiment of the present application relates to a method for improving the downlink quality of a voice service, as shown in FIG. 3 , including:

Step 301 , in response to the third instruction, judging whether the physical downlink control channel PDCCH of the cell where the target UE is located has residual power, and the target UE is a UE processing voice services.

In this embodiment, the voice service quality on the PDCCH is mainly improved.

In an embodiment, before step 301, it also includes: detecting the current block error rate of the PDCCH of the voice service of the target UE, when the current block error rate of the PDCCH is higher than the second target block error rate and the CCE aggregation degree of the voice service of the target UE In the case of the preset polymerization degree upper limit value, a third instruction is generated.

It should be noted that a CCE (Control Channel Element, control channel element) is a basic unit constituting a PDCCH, and the number of CCEs in a PDCCH is called an aggregation degree. When sending PDCCH, you can decide how many aggregation degrees to use to send control information according to the actual wireless channel environment. When the wireless channel environment is relatively bad, using a large aggregation degree can obtain better demodulation performance; in the wireless channel environment is better , a smaller degree of polymerization is used. In this embodiment, the preset upper limit of the degree of aggregation can be defined and set according to application scenarios, network conditions, and business requirements. For example: for VoLTE, the upper limit of the aggregation degree can be set to 8, and for VoNR, the upper limit of the aggregation degree can be set to 16. When the current block error rate of the PDCCH is higher than the second target block error rate and the CCE aggregation degree of the voice service of the target UE is the preset upper limit of the aggregation degree, it means that the quality of the voice service is poor at this time, and a third instruction trigger needs to be generated Power up operation.

Step 302: If the PDCCH of the cell where the target UE is located has residual power, power is added to the PDCCH of the voice service of the target UE based on the residual power.

In this embodiment, step 302 specifically includes: adding power to the PDCCH of the voice service of the target UE based on the remaining power and the preset second power adding step. Each time after adding power to the PDCCH of the voice service of the target UE, the current block error rate of the PDCCH needs to be re-detected; and when the current block error rate of the re-detected PDCCH is higher than the preset second target block error rate, generate Third instruction. It should be noted that the remaining power in this embodiment may be the entire downlink available power, or the downlink available power of the voice service. In addition, the second power-up step length can be adjusted by yourself.

In an embodiment, after step 302, the method further includes: reducing the power of the PDCCH of the voice service of the target UE in response to the fourth instruction. In addition, in response to the fourth instruction, reducing the PDCCH power of the voice service of the target UE specifically includes: reducing the power of the PDCCH of the voice service of the target UE based on the preset second power reduction step in response to the fourth instruction. Every time the power of the PDCCH of the voice service of the target UE is reduced, the current block error rate of the PDCCH of the voice service of the UE needs to be re-detected; and the current block error rate of the re-detected PDCCH is lower than the preset second target block error rate In the case of , a fourth instruction is generated.

It can be understood that after each power up operation or power down operation, it is necessary to re-detect the current block error rate of the PDCCH of the voice service of the target UE, and determine the required block error rate according to the current block error rate and the second target block error rate. operate.

A method for improving the downlink quality of voice services proposed in this application is to add power to the PDCCH based on the remaining power of the physical downlink control channel PDCCH in the cell where the target UE is located, which can significantly improve the downlink quality of voice services.

The embodiment of the present application relates to a method for improving the downlink quality of the voice service, including: based on the method for improving the downlink quality of the voice service described in the above embodiment, increasing the power of the PDSCH of the voice service of the target UE; and/or, based on the above implementation The method for improving the downlink quality of the voice service described in the example is to increase the power of the PDCCH of the voice service of the target UE.

If in the same scheduling period, the current power of the PDSCH of the voice service of the target UE and the current power of the PDCCH of the voice service of the target UE exceed the downlink power threshold of the voice service of the target UE, put the control signaling of the voice service of the target UE on the next Scheduling periodic sending. Wherein, when the PDSCH of the voice service of the target UE is powered up, the current power of the PDSCH is the power after the power is added; when the PDCCH of the voice service of the target UE is powered up, the current power of the PDCCH is the power after the power is added. power.

It should be noted that the method of adding power to the PDSCH of the voice service of the target UE is basically the same as that of steps 101 to 103 and steps 201 to 205, and will not be repeated here. The method and steps of adding power to the PDCCH of the voice service of the target UE Steps 301 to 302 are basically the same and will not be repeated here.

Those skilled in the art can understand that the PDSCH mainly carries user data, and the PDCCH mainly carries control signaling. When the user data on the PDSCH and the control signaling on the PDCCH are scheduled in the same TTI (Transport Time Interval, transmission time interval) At this time, if the sum of the current power of the PDSCH of the voice service of the target UE and the current power of the PDCCH of the voice service of the target UE exceeds the downlink power threshold of the voice service of the target UE, the control signaling of the voice service of the target UE is released. to be sent in the next scheduling cycle. In this way, the downlink quality of the voice service can be fully guaranteed.

A method for improving the downlink quality of the voice service proposed in this application can significantly improve the downlink quality of the voice service by increasing the power of the PDSCH of the voice service of the target UE and the power of the PDCCH of the voice service of the target UE. When the PDCCH and PDCCH are scheduled in the same TTI and the power is insufficient, the control signaling of the voice service of the target UE is sent in the next scheduling cycle, which guarantees the downlink quality of the voice service first.

In addition, it should be understood that the division of steps in the above methods is only for clarity of description, and may be combined into one step or split into multiple steps during implementation. As long as the same logical relationship is included, all Within the scope of protection of this application; adding insignificant modifications to the process or introducing insignificant designs without changing the core design of the process is within the scope of protection of this application.
