Background technique

In the entire mobile network equipment, the base station equipment consumes the most power, and its power consumption has accounted for 50% to 80% of the wireless energy consumption.

Using carrier shut-off to reduce base station energy consumption has high requirements for base station deployment and easily affects user experience. Moreover, since carrier shut-off can only be performed on cells with a certain capacity, the scope of application is narrow.

The use of symbolic shutdown (or time slot shutdown) to reduce the energy consumption of the base station requires high turn-off and turn-on time, which is likely to cause incomplete turn-off, and due to frequent turn-off and turn-off, the energy-saving effect is not good.

Using channel shutdown to reduce the energy consumption of the base station is not flexible enough and will cause the coverage of the base station to decrease, which will affect the user experience.

detailed description

In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the method and device for shutting off base station channels, electronic equipment, and computer-readable media provided by the present disclosure will be described in detail below in conjunction with the accompanying drawings.

Hereinafter, the embodiments of the present disclosure will be more fully described with reference to the accompanying drawings, but the illustrated embodiments may be embodied in different forms, and should not be construed as being limited to the embodiments set forth in the present disclosure. On the contrary, the purpose of providing these embodiments is to make the present disclosure thorough and complete, and to enable those skilled in the art to fully understand the scope of the present disclosure.

The drawings of the embodiments of the present disclosure are used to provide a further understanding of the embodiments of the present disclosure, and constitute a part of the specification, and are used to explain the present disclosure together with the embodiments of the present disclosure, and do not constitute a limitation to the present disclosure. By describing detailed example embodiments with reference to the accompanying drawings, the above and other features and advantages will become more apparent to those skilled in the art.

The embodiments of the present disclosure may be described with reference to plan views and/or cross-sectional views with the help of ideal schematic diagrams of the present disclosure. Therefore, the example illustrations may be modified according to manufacturing technology and/or tolerances.

In the case of no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

The terms used in the present disclosure are only used to describe specific embodiments, and are not intended to limit the present disclosure. The term "and/or" as used in this disclosure includes any and all combinations of one or more related listed items. The singular forms "a" and "the" as used in this disclosure are also intended to include plural forms, unless the context clearly dictates otherwise. As used in the present disclosure, the terms "including" and "made of" designate the presence of the described features, wholes, steps, operations, elements and/or components, but do not exclude the presence or addition of one or more other features, Whole, steps, operations, elements, components and/or groups thereof.

Unless otherwise defined, the meanings of all terms (including technical and scientific terms) used in the present disclosure are the same as those commonly understood by those of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of the related technology and the present disclosure, and will not be interpreted as having idealized or excessive formal meanings, Unless the present disclosure is specifically so limited.

The embodiments of the present disclosure are not limited to the embodiments shown in the drawings, but include modifications of configurations formed based on manufacturing processes. Therefore, the regions illustrated in the drawings have schematic properties, and the shapes of the regions shown in the figures exemplify the specific shapes of the regions of the elements, but are not intended to be limiting.

In the present disclosure, "channel" refers to the radio frequency transmission path on the base station to send and receive signals with the terminal. The path may include the antenna, power amplifier, small signal processing module, transceiver module, and digital intermediate frequency module located in the base station. Wait. Therefore, the turning off of the channel referred to in the present disclosure may be, for example, turning off one or more of the antenna, power amplifier, small signal processing module, transceiver module, and digital intermediate frequency module, so as to achieve the purpose of energy saving. It can be turned off by setting hardware such as logic circuits, and it can be turned off by setting software. For example, a base station has 64 antennas, corresponding to the 64 above-mentioned radio frequency transmission paths (that is, channels). Therefore, according to the present disclosure, the radio frequency transmission paths (that is, channels) corresponding to part of the antennas can be closed, so that the part The antenna and its corresponding upstream and downstream circuit elements (such as power amplifier/small signal processing module/transceiver module/digital intermediate frequency module) are in a closed state (that is, not working or standby), so as to achieve the purpose of energy saving.

In the first aspect, referring to FIG. 1, the present disclosure provides a method for shutting down a base station channel, which may include step S101 and step S102.

In step S101, the operating status information of the base station is acquired.

The current operating status information of the operating base station, such as the current business volume of the base station, is obtained through a device (such as a server) that controls the shutdown of the base station channel.

In step S102, if the operating state information satisfies the preset first condition, at least part of the channels of the base station is shut down according to the operating state information.

For example, after the server receives the operating status information of the base station, it judges the operating status information to determine whether it meets the first condition, where the first condition is a preset condition, and different base stations can be set according to actual conditions. The first condition.

If the first condition is met, the base station channels that need to be shut down are determined according to the operating state information, and these channels are shut down. When the operating status of the base station is different, the base station channels that need to be shut down are obviously different. For example, when the service volume of the base station is different, the number of base station channels that need to be shut down is obviously different.

In some related technologies, a fixed base station channel is turned off at a fixed time period (such as a normal business idle period). However, the actual base station's business volume does not always change according to the law of time, so it is turned off at a fixed time period. The way of the base station channel may cause the base station channel to be shut down by mistake when the base station has a large traffic volume, which affects the service quality of the base station and the user experience, or the channel is not shut down when the traffic volume is small, which cannot fully save energy.

Compared with shutting down fixed base station channels, when the base station has a large amount of traffic, the method for shutting down base station channels according to the embodiment of the present disclosure shuts down fewer base station channels according to operating status information to ensure the base station service quality; when the base station's service volume changes After less time, the method for shutting down base station channels in the embodiments of the present disclosure judges based on the operating state information, and shuts down more base station channels, which saves more energy consumption. Therefore, the method for shutting down the channel of the base station according to the embodiment of the present disclosure shuts down the channel of the base station according to the operating status information of the base station, and different operating status information corresponds to different channels being closed, making full use of the service tidal effect and having strong flexibility.

2, in some embodiments, if the operating status information meets the preset first condition, shutting down at least part of the channel of the base station according to the operating status information (S102) includes: within a preset time period, if the operating status If the information satisfies the preset first condition, at least part of the channels of the base station is shut down according to the operating state information.

If the current time is not within the preset time period, even if the operating status information of the base station meets the first condition, the base station channel is still not shut down, or the server only obtains the operating status information of the base station and makes a judgment within the preset time period.

This is because some base stations set up in special areas (such as prosperous areas) at some time points (such as daytime) operating status information (such as traffic) below the threshold may be accidental, the operating status information of the base station (such as Traffic) has a high probability that it will soon exceed the threshold. If the base station channel is turned off, there is a high probability that the user experience will be affected. In order not to continue to affect the user experience, the channel of the base station that has just been shut down may need to be opened immediately. Frequent switching of the channel of the base station will affect the energy-saving effect. Therefore, the operating state information of the base station is acquired and judged only within a preset time period (such as night), which reduces the impact on user experience.

2, in some embodiments, the operating status information includes at least one of the traffic volume of the base station, the power of the base station, the physical resource block utilization rate of the base station, and the number of terminals connected to the base station; the first condition includes at least one of the following Item: The service volume of the base station is lower than the preset shutdown service volume threshold; the power of the base station is lower than the preset shutdown power threshold; the utilization rate of the physical resource block of the base station is lower than the preset shutdown physical resources Block utilization threshold; the number of terminals connected to the base station is lower than the preset threshold for the number of shutdown terminals.

The operating status information of the base station obtained by the server may include the service volume of the base station, the power of the base station, the utilization rate of the base station PRB (Physical Resource Block, physical resource block), and the number of terminals connected to the base station.

Among them, the business volume of a base station refers to the total amount of various services performed by the base station and terminals. When the base station has a large traffic volume, or when the business is busy, the base station channels may all carry services and the carried traffic volume may be close to Its business volume limit. At this time, if some channels of the base station are turned off, it will have a great impact on the base station’s business, which may cause a huge drop in user experience; and when the base station’s business volume is small, or when the business is relatively idle, some of the base station’s channels may not be There is no bearer service or there is a large gap between the channel bearer service volume of most base stations and the limit of the channel. Therefore, shutting down some base station channels has less impact on base station services and has less impact on user experience.

The power of a base station refers to the power at which the base station transmits and receives wireless signals. The nature of the base station’s transmission and reception of wireless signals is the business process of the base station and terminals. Therefore, similar to the base station’s business volume, when the base station has high power, most base station channels may be They all carry services and the carried service volume may be close to the limit of the service volume that can be carried; and when the power of the base station is small, some base station channels may not carry service or most of the base station channels have a large gap between the service volume and the channel limit. Therefore, when the power of the base station is low, shutting down some base station channels has less impact on the base station business and less impact on user experience.

The base station PRB utilization rate refers to the utilization rate of the resources of 12 consecutive carriers in the frequency domain of the base station. The higher the PRB utilization rate of the base station, the more carrier resources the base station uses. Correspondingly, the more base station channels it uses or It is said that the more services carried by each base station channel; the lower the PRB utilization rate of the base station, the less the carrier resources used by the base station. Correspondingly, the fewer base station channels it uses or the services carried by each base station channel The less. Therefore, when the PRB utilization rate of the base station is low, shutting down some base station channels has less impact on the base station business and less impact on user experience.

The number of terminals connected to the base station refers to the number of terminals that conduct business with the base station. The more terminals that conduct business with the base station, the more base station channels are obviously needed to carry services or each base station channel needs to carry more services; The fewer terminals that carry out services, the fewer the number of base station channels that need to carry services, or the fewer the services that each channel needs to carry; therefore, when the number of terminals connected to the base station is small, turning off some base station channels will cause base station services. The impact is small, and the impact on the user experience is also small.

These parameters can well reflect the current busyness of the base station and the occupation of the base station channel.

After obtaining the above-mentioned operating status information (ie, the base station's business volume, base station power, base station PRB utilization rate, and the number of terminals connected to the base station), the server determines whether the operating status information meets the first condition. The first condition may be obtained specifically A specific value of the operating status information is lower than the corresponding preset shutdown threshold, for example, the traffic volume of the base station is lower than the preset shutdown traffic threshold or the power of the base station is lower than the preset shutdown power The threshold value or the utilization rate of the physical resource block of the base station is lower than the preset shut-off physical resource block utilization threshold value or the number of terminals connected to the base station is lower than the preset shut-off terminal number threshold.

In one embodiment, the base station is a 64-antenna base station. When one of the following four conditions is met, the first condition can be considered to be satisfied, and part of the channels of the base station can be shut down.

Condition 1. The service volume of the base station is lower than the preset shut-off service volume threshold.

Condition 2. The power of the base station is lower than the preset shut-off power threshold.

Condition 3: The PRB utilization rate of the base station is lower than the preset shutdown physical resource block utilization threshold.

Condition 4: The number of terminals connected to the base station is lower than the preset threshold for the number of shut-off terminals.

In one embodiment, the service volume of the base station can be obtained preferentially. If the service volume of the base station is lower than the cut-off service volume threshold, it can be directly considered that the first condition has been met, and there is no need to obtain other operating status information. The service volume of the base station shuts down part of the base station channels; if the service volume of the base station is higher than the shut-off service volume threshold, then continue to obtain other operating status information (such as the power of the base station, etc.) and make judgments.

The first condition may also be that multiple specific values of the acquired operating state information are lower than corresponding preset thresholds.

In one embodiment, when the operating state information of the base station satisfies the following at least two conditions, the first condition may be considered to be satisfied, and part of the channels of the base station may be shut down.

In one embodiment, a certain weight can be set for each condition (for example, condition 1 has a weight of 30, condition 2 has a weight of 25, condition 3 has a weight of 30, and condition 4 has a weight of 15). The weights of the conditions are added to obtain a score (for example, conditions 1 and 3 are met, the score is 60), and if the score meets a certain condition (for example, greater than or equal to 60), the first condition is considered to be satisfied.

Of course, the first condition may also be that all specific values of the acquired operating state information are lower than the corresponding preset threshold value.

In one embodiment, when the operating state information of the base station satisfies all the following conditions, it can be considered that the first condition is satisfied, and only partial channels of the base station can be shut down.

For different base stations, different thresholds and first conditions can be flexibly set. For example, if the services performed by a base station are mostly important services, the threshold can be set to a lower value, and the first condition can be set to a more demanding one. Conditions (for example, all specific values of the acquired operating status information are lower than the corresponding preset thresholds).

2, in some embodiments, after obtaining the operating status information of the base station (S102), the method further includes: Step S103: If the operating status information meets a preset second condition, all channels of the base station are opened.

The second condition includes at least one of the following: the service volume of the base station is higher than the preset restart service volume threshold, where the restart service volume threshold is higher than the shutdown service volume threshold; the power of the base station is higher than the preset The restart power threshold is higher than the shutdown power threshold; the physical resource block utilization of the base station is higher than the preset restart physical resource block utilization threshold, where the restart physical resource The block utilization threshold is higher than the shutdown physical resource block utilization threshold; the number of terminals connected to the base station is higher than the preset restart terminal number threshold, where the restart terminal number threshold is higher than the shutdown terminal Number threshold.

After the server obtains the operating status information of the base station, once it determines that the operating status information no longer meets the preset first condition, it immediately opens all channels of the base station. When the operating status information of the base station jumps near the first condition, it is easy The channel of the base station is frequently switched on and off (that is, the ping-pong effect).

For example, the first condition is that the service volume of the base station is lower than the preset shutdown service volume threshold, and the service volume of the base station fluctuates near the shutdown service volume threshold, it is possible that the service volume of the base station acquired at the current moment is lower than The preset cut-off service volume threshold requires some base station channels to be shut down. The traffic volume of the base station acquired at the next moment is higher than the preset cut-off service volume threshold. All base station channels need to be opened, resulting in Frequent closing and opening of base station channels.

In order to avoid this situation, the method for shutting down base station channels in the embodiments of the present disclosure sets and shuts down thresholds (that is, shut-off traffic thresholds, shut-off power thresholds, and shut-off physical resource block utilization rates. Threshold value, shutdown terminal number threshold) corresponding to the restart threshold, that is, the restart traffic threshold corresponding to the shutdown traffic threshold, and the restart power threshold corresponding to the shutdown power threshold Value, the restart physical resource block utilization threshold corresponding to the shutdown physical resource block utilization threshold, the restart terminal number threshold corresponding to the shutdown terminal number threshold, each restart threshold is high Corresponding to the shutdown threshold. When the operating status information of the base station exceeds the shutdown threshold but does not exceed the restart threshold, all base station channels are not opened, but all base station channels are opened after the operating status information of the base station exceeds the restart threshold. For example, when the service volume of the base station exceeds the cut-off service volume threshold, all the base station channels are not opened, but all the base station channels are opened after the service volume of the base station exceeds the restart service volume threshold.

Since the restart threshold is higher than the shutdown threshold, it is equivalent to the base station's operating status information needs to be higher than the shutdown threshold to a certain extent before the channel restarts, and because the base station's operating status information has significantly exceeded the shutdown threshold during restart Therefore, in most cases, the operating status information of the base station will not become lower than the shutdown threshold again in a short period of time, so as to avoid frequent shutdown and opening of the base station channel in a short time.

Of course, if the remaining base station channels are in an abnormal state after some base station channels are turned off, or the time is no longer within the preset time period, then the base station channels may not be shut down any more and the closed base station channels can be restarted.

3, in some embodiments, if the operating status information satisfies the preset second condition, opening all channels of the base station (S103) includes: when the distance was last performed the step of turning off at least part of the channels of the base station according to the operating status information When the time exceeds the predetermined time, if the operating status information meets the preset second condition, all channels of the base station are opened.

In order to avoid the ping-pong effect, you can also set a timer while turning off the channel of the base station. Before the timer is turned off, even if the operating status information of the base station does not meet the first condition, the channel of the base station that has been shut down will not be reopened, thereby ensuring the base station After the channel is turned off, it will not be reopened within the time period when the timer is not turned off (that is, the channel will not be reopened within a short period of time after it is turned off).

Similarly, when the base station channel is reopened, the timer is also set. Before the timer is turned off, the base station channel is not shut down even if the base station's operating status information meets the first condition to ensure that the base station channel is not turned off after the base station channel is opened. It will not be switched off again within the period of time, thus avoiding the frequent opening and closing of the base station channel in a short period of time.

3, in some embodiments, the operating status information includes at least one of the traffic volume of the base station, the power of the base station, the physical resource block utilization rate of the base station, and the energy consumption of the base station when different numbers of channels are turned off; Turning off at least part of the channels of the base station (S102) according to the status information may include: step S1021, at least according to the traffic volume of the base station, the power of the base station, the utilization rate of physical resource blocks of the base station, and the energy consumption of the base station when different numbers of channels are turned off. One is to determine the number of base station channels that need to be shut down.

After judging that the operating state information satisfies the first condition, the server adaptively determines the number of base stations that need to be shut down according to different operating state information.

For example, the PRB utilization rate of the base station is periodically recorded, and the following formula is used to filter the recorded PRB utilization rate of the base station to obtain the filtered PRB utilization rate in consideration of the fluctuation of the operating status information.

PRB utilization rate _filter (n) = α × PRB utilization rate (n) + (1-α) × PRB utilization rate _filter (n-1)

Among them, the PRB utilization rate _filter (n-1) is the PRB utilization rate of the base station obtained by the n-1th filtering, PRB utilization rate (n) is the PRB utilization rate of the base station recorded for the nth time, and the PRB utilization rate _filter (n ) Is the PRB utilization rate of the base station obtained by the nth filtering, and α is the filtering smoothing factor, which can be artificially set according to actual conditions, or can be obtained through data learning.

According to the different PRB utilization _filter (n) values obtained by filtering, switch off different numbers of channels. If the filtered PRB utilization _filter (n) is less than the set first threshold, then select to shut down all channels of the base station

(Refer to Figure 4), if the PRB utilization _{filter (n) obtained by filtering is} less than the second threshold set, then select to turn off all channels of the base station

(Refer to Figure 5), if the PRB utilization _{filter (n) obtained by filtering is} less than the set third threshold, then select to turn off all channels of the base station

(Refer to Figure 6).

In Figures 4 to 6, each cross position represents two channels (the channel number is represented by P0 to P63, that is, the base station has 64 channels in the figure), and the cross position surrounded by a dashed frame in the figure means that it is closed. Broken channel.

Of course, the number of closed channels can also be determined in a similar way according to the base station's business volume and base station power, or the number of closed channels can be determined by comprehensively considering the base station's business volume, base station power, and base station PRB utilization, such as The traffic volume of the base station, the power of the base station, and the PRB utilization rate of the base station are given different weights.

Since the number of channels in the base station is not linearly related to the energy consumption of the base station, the energy consumption changes of the base station when different numbers of base station channels are shut down can be considered on the basis of the operating status information of the base station, such as shutting down all base stations. Channel

Although it is better than turning off all base station channels

The energy consumption is 30% more, but the service volume of each base station channel that is not shut down needs to be 70% more. At this time, comprehensive consideration is needed.

Switching off different numbers of channels according to different operating status information of the base station can achieve the best energy saving effect with minimal impact on the service of the base station.

3, in some embodiments, the operating status information includes the degree of matching between the base station's beam weight and the current terminal channel information when the channels at various locations are turned off, and the energy consumption of the base station when the channels at various locations are turned off. At least one; shutting down at least part of the channel of the base station according to the operating status information (S102) includes: step S1022, according to the degree of matching between the base station's beam weight and the current terminal channel information when the channels in different positions are shut down, and the shut-off is different The location of the channel is at least one of the energy consumption of the base station, and the location of the channel that needs to be shut down is determined.

After the server judges that the operating state information meets the first condition, it adaptively determines which one needs to be turned off according to different operating state information (such as the degree of matching between the base station's beam weight and the current terminal channel information when the channels at different locations are turned off) The location of the base station, such as row off (refer to Figure 5), column off (refer to Figure 6), block off (refer to Figure 4).

Among them, the rows and columns refer to the rows and columns arranged by the channels in the antenna array of the base station, that is, the rows and columns in Figs. 4, 5, and 6. In Figures 4 to 6, each cross position represents two channels (the channel number is represented by P0 to P63, that is, the base station has 64 channels in the figure), and the cross position surrounded by a dashed frame in the figure means that it is closed. Broken channel.

Switching off channels in different locations will cause the base station's beam weight to change, and the terminal communicates with the base station through beams. The services of terminals in different locations are handled by different beams. Therefore, it needs to be determined according to the location of the terminal that is currently doing business. The beam weight needed to further determine the position of the channel that is turned off.

For example, the channel matrix of the terminal equipment measured by the base station is correlated with the beam weights when the channels at different positions are turned off, and the off channels corresponding to the beam weights with more correlation are turned off first.

For example, if the current service of the base station is mainly for terminals in a building, because the channels of different rows of the base station can cover areas in different height ranges, when the channel of the column base station is turned off, the beam weight is more related to the channel matrix of the terminal device. Therefore, multiple columns of base station channels can be turned off, leaving some columns of base station channels; if the current service of the base station is mainly for terminals in one area, because different columns of the base station can cover different plane areas, the beam weight is when the base station channel is turned off It has greater correlation with the channel matrix of the terminal equipment, so multiple rows of base station channels of the base station can be turned off, and some rows of base station channels of the base station can be reserved.

Although the number of shut-off channels is the same, the energy consumption of the base station for shutting down channels at different locations may be different. Therefore, it is necessary not only to consider the degree of adaptation between the location of the shut-off channel and the current base station business, but also to shut down the channels at different locations. The energy consumption of the base station during the channel. If the base station channel in the column direction is also turned off, the energy consumption is different when the base station channels of different columns are turned off. Under the conditions that can meet the current business, turning off the columns with more energy consumption can obviously save more Base station energy consumption.

According to the different operating status information of the base station, the channels at different positions are shut down to achieve the best energy-saving effect with the least impact on the base station's business.

3, in some embodiments, the operating status information includes at least one of the signal-to-noise ratio of the uplink channel, the energy consumption of the base station when the downlink channel is turned off, and the energy consumption of the base station when the uplink channel and the downlink channel are simultaneously turned off; according to The operating status information shutting down at least part of the channel of the base station (S102) includes: step S1023, according to the signal-to-noise ratio of the uplink channel, the energy consumption of the base station when shutting down the downlink channel and the energy consumption of the base station when both the uplink channel and the downlink channel are shut down. At least one of determining to turn off the downlink channel of at least part of the channel of the base station or to turn off the uplink channel and the downlink channel of at least part of the channel of the base station.

After judging that the operating state information meets the first condition, the server adaptively determines to turn off only the downlink channel of the partial channel of the base station or the uplink channel and the downlink channel of the partial channel of the base station according to different operating state information.

Among them, the downlink is the base station actively sending signals to the terminal, which is a transmission process for the base station, so the energy consumption of the downlink channel is relatively large; while the uplink is the base station receiving the terminal signal, which is only the receiving process for the base station, so the energy of the uplink channel The consumption is small. Therefore, if conditions permit, both the upstream channel and the downstream channel can be turned off for better energy saving; and if only one of the upstream channel and the downstream channel can be turned off, usually only the downstream channel is turned off instead of The upstream channel will be shut down separately.

Exemplarily, if the signal-to-noise ratio of the signal (uplink signal) received by the current base station from the terminal is low and lower than the threshold, it means that the base station cannot receive the uplink signal from the terminal well, and the uplink channel cannot be turned off ( Otherwise, the signal-to-noise ratio will be further reduced), and only the downstream channel can be turned off.

If the signal-to-noise ratio of the signal from the terminal received by the current base station is high and exceeds the threshold, it means that the base station can receive the uplink signal well, and it is possible to shut down the uplink channel. When the channel and the downlink channel are turned off, and when only the downlink channel is turned off, the power consumption of the base station determines how to turn off the channel (that is, whether the uplink channel is also turned off according to whether the additional energy saving effect when turning off the uplink channel is obvious).

3, in some embodiments, after shutting down at least part of the channels of the base station according to the operating status information (S102), the method further includes: step S1024, increasing the power spectral density of the unclosed channels in the base station; and/or, according to the base station Set the beam weight for the channels that are not turned off.

After the server shuts down some of the channels of the base station based on the operating status information, this part of the channel may also carry services before. This part of the service cannot be discarded, but needs to be transferred to other channels. In order to meet the needs of newly added services, it is not closed. The power spectral density of the off channel needs to be increased.

While increasing the power density spectrum of the remaining channels, it is also necessary to prevent the single channel power from exceeding the rated power (for example, by limiting the number of scheduled PRBs to prevent the single channel power from exceeding the rated power). For example, increase the power spectral density of the remaining channels by 3dB, while limiting the maximum number of scheduled PRBs to half of the maximum bandwidth to ensure that the maximum generated power of each channel does not exceed the rated power.

At the same time, it is also possible to recalculate the beam weights for the remaining channels based on the number of closed channels and the positions of the closed channels. The principle of weight calculation should try to keep the beam coverage as close as possible before the shutdown. Doing so can ensure that the service between the terminal and the base station is minimally affected.
