If a certain threshold is met, the cell base station is switched from Multiple Input Multiple Output (MIMO) to Single Input Multiple Output (SIMO). In a popular sense, if there are 64 channels originally , may become 32 channels or 16 channels depending on the business volume, but still use 64 antennas for transmission, which will reduce the data throughput of the base station and reduce the coverage, because turning off the power amplifier of one or more channels will cause the output Signal energy is reduced.

It can be understood that the room access system includes at least one baseband processing unit 100 and at least one remote radio frequency unit 300. Referring to Figure 3, the baseband processing unit 100 applied to the room access system proposed according to the embodiment of the present application Energy saving methods include:

Step S110: Generate a channel switch information set corresponding to the belonging data according to the belonging data of at least one user terminal; wherein the user terminal is communicatively connected to the remote radio frequency unit 300.

It should be noted that the attribution data can be periodically scheduled or triggered by trigger conditions (for example, if the total power consumption is greater than the preset value, the attribution data will be detected at least once continuously, and if it enters the peak usage period, the detection will be performed. , the detection of belonging data is not triggered during non-peak hours). The belonging data is used to represent the belonging relationship between the user terminal and the remote radio frequency unit 300, that is, which one or several remote radio frequency units 300 the user terminal belongs to.

It should be noted that the acquisition of the belonging data can be calculated by initiating a query request to the user terminal through a periodic scheduling task, such as initiating an uplink measurement to the user terminal and receiving an uplink reference signal responded by the user terminal, and based on the reference measurement information of the uplink reference signal The size of the power is determined by the micro RRU (Radio Remote Unit) corresponding to each online UE. In other embodiments, it may also be determined based on the scheduling status of each user terminal (whether it is scheduled). In the embodiment of the present application, the acquisition of the belonging data is determined by the reference measurement information power corresponding to the upper and lower reference signals.

Step S120: Open or close multiple communication channels between the baseband processing unit 100 and at least one user terminal according to the channel switch information set.

It should be noted that the multiple communication channels include at least one of a carrier channel, a slot channel and a symbol channel. Closing is a soft shutdown process to reduce business volume or turn off the power amplifier to achieve communication with the user terminal without interrupting Under the circumstances, reduce energy consumption as much as possible. The multiple communication channels are channels configured on the link nodes in the room access system between the baseband processing unit and the user terminal, such as the carrier channel, slot channel and symbol channel on the RRU, or on the bridge device 200 The carrier channel, slot channel and symbol channel configured on.

In other embodiments, the channel information includes [BBU bridge device 200 number, micro RRU number, slot switch information, symbol scheduling start, symbol scheduling end]. At this time, slot switch information, symbol scheduling start, symbol scheduling end Used to indicate the status of each sub-channel in the scheduling channel.

Therefore, by generating a channel switch information set corresponding to the belonging data, and then softly turning off or opening multiple communication channels between the baseband processing unit 100 and the user terminal according to the channel switch information set, the power consumption of the communication channels is controlled. , Therefore, the energy-saving method of the embodiment of the present application can reduce the network operation energy consumption of the room access system, and the energy-saving effect is better.

Step S120: According to the channel switch information set, the baseband processing unit 100 and at least one user terminal are Opening or closing multiple communication channels between them, including: for each communication channel, determining the corresponding comprehensive switch state of the communication channel according to the attribution data contained in the corresponding channel switch information and the enable status of the channel; according to the comprehensive switch status of each communication channel Switch status to open or close the communication channel. By judging the comprehensive switching status, the probability of frequent switching of communication channels is reduced.

It should be noted that each channel switch information is used to open or close a communication channel. The attribution data can be used to determine the enable status of the channel on the communication channel where the UE is located. The enable status of the channel indicates It is to open or close the communication channel. If the enable status is enabled, the communication channel is opened. If the enable status is disable, the communication channel is closed.

It should be noted that for the same communication channel, there are situations where multiple user terminals share it. For example, if there are multiple user terminals connected to the same RRU, in this case, the channel switch information of multiple user terminals under the same RRU needs to be Perform union processing, that is, determine all enable states under the same RRU based on the attribution data, and then obtain the comprehensive switch status and update the channel switch information set.

In some embodiments, as shown in FIG. 4 , a level 3 bridge device 200 is connected to the baseband processing unit 100 , and 8 micro RRUs are connected to each bridge device 200 , for a total of 24 micro RRUs. Each micro RRU includes Multiple frequency bands. Taking the carrier channel as an example, before completing the delivery of the information group, the baseband processing unit 100 determines whether multiple UEs belong to the same bridge device 200 or micro-RRU. As shown in Figure 4, bridge device 3 and the ones connected to the bridge device 3 Micro RRU#3 has the situation that UE2/3 is scheduled at the same time. It is necessary to combine the switch status of UE2/3 on RRU#3 and then send it uniformly. At this time, the three bridge devices 200 receive the baseband processing unit 100 and send it. Signal, analyze and extract information related to this device and the 8 micro-RRUs attached to it. The information received by bridge device 1 is [1,1,1], [1,2,1], [1,3,1] , [1,4,0], [1,5,0], [1,6,0], [1,7,0], [1,8,0]; the information received by bridge device 2 is [ 2,1,0], [2,2,0], [2,3,0], [2,4,1], [2,5,0], [2,6,0], [2, 7,0], [2,8,0]; the information received by bridge device 3 is [3,1,1], [3,2,1], [3,3,1], [3,4, 1], [3,5,0], [3,6,0], [3,7,0], [2,8,0]. For the bridge device 200 itself, according to the carrier configuration Set the information and directly switch the channel data. For example, for the carrier channel of UE1, bridge device 1 only turns on the carrier channel where micro-RRU#1/2/3 is located, and turns off the carriers of other channels; bridge device 2 targets the carrier channel of UE2. , only the carrier channel where micro RRU#4 is located is turned on, and other channels are turned off. For the carrier channels of UE2/3, bridge device 3 only turns on the carrier channel where micro RRU#1/2/3/4 is located, and other channels are turned off. Carrier is turned off. For micro RRUs, the BBU bridge device 200 delivers the extracted messages to 8 micro RRU devices. Micro RRU#1/2/3 under bridge device 1 resolves to switch 1, and the micro RRU under bridge device 2 #4 resolves to switch 1, micro-RRU#1/2/3/4 under BBU bridge device 3 resolves to switch 1, other micro-RRUs resolves switch information to 0, and the micro-RRU with value 1 opens the channel , if it is 0, the carrier will be turned off.

In some embodiments, referring to FIG. 5 , taking a bridge device 200 under the baseband processing unit 100 as an example, the baseband processing unit 100 simultaneously obtains real-time scheduling information of UE1/UE2 according to the NR standard frame format. Assume that UE1/UE2 downlink is only valid in D and S time slots. UE1 has scheduling on D time slot symbols 0-3 and S time slot symbols 0-4; UE2 has scheduling on D time slot symbols 2-7. Scheduling, there is scheduling on symbols 0-6 of the S time slot. According to the NR standard frame format and the real-time scheduling of UE1/UE2, the slot and symbol switch information group of UE2 is generated according to the bridge device 200 number and the micro RRU number. The switch information includes [BBU bridge device number, micro RRU number, slot switch information, Symbol scheduling starts, symbol scheduling ends], and the information group is sent in advance according to each slot. Before completing the information group delivery, the baseband processing unit 100 determines whether multiple UEs belong to the same bridge device 200 or micro-RRU. As shown in Figure 3, the bridge device 200 and the micro-RRU #4/5 connected to the bridge device 200 In the case of simultaneous scheduling, the information groups need to be combined and then issued uniformly. The information is sent from the baseband processing unit 100 to the bridge device 200 and then to the micro RRU device. In order to ensure fast and accurate transmission of the information group, a physical link transmission channel is used together with the service data, which is sent from the baseband processing unit 100 to the bridge device 200 and then to the micro RRU device. For micro RRUs, the bridge device 200 delivers the extracted communication channel switching messages to eight micro RRU devices respectively by port. For the D time slot, micro-RRU#1/2/3 parses the switch of symbols 0-3 as 1, and the switch of symbols 4-13 as 0; micro-RRU#4/5 parses the switch of symbols 0-7 as 1, and the switch of symbols 8-13 is 0; micro-RRU#6/7/8 parses symbols 2-7 switches to 1, symbols 0-1, 8-13 switches to 0; S time slot, micro-RRU#1/2/3 parses symbols 0-4 switches is 1, the switch of symbols 5-13 is 0; the micro RRU#4/5 resolves the switch of symbols 0-6 to 1, and the switch of symbols 7-13 is 0; the micro RRU#6/7/8 resolves the switch of symbols 0-6 to 1 , the switches of symbols 7-13 are 0; for the U time slot, all the symbol switches parsed by all micro PRRUs are 0; according to the analysis, the micro RRU with a value of 1 opens the channel, and the one with a value of 0 closes the channel.

It can be understood that step S120, opening or closing multiple communication channels between the baseband processing unit 100 and at least one user terminal according to the channel switch information set, includes: sending the channel switch information set to the remote radio frequency unit 300, The remote radio frequency unit 300 is caused to open or close the configured first communication channel according to the channel switch information set; wherein the first communication channel is one of multiple communication channels.

It should be noted that the opening and closing of the first communication channel is soft processing, such as turning off the power amplifier or symbol channel, etc. In some embodiments, when the channel switch information set represents the switching state of the carrier channel, the first channel represents the carrier channel; when the channel switch information set represents the scheduling channel, such as slot channel, symbol channel, then the first channel represents Scheduling channel.

It can be understood that the room access system also includes a bridge device 200. Step S120 is to open or close multiple communication channels between the baseband processing unit 100 and at least one user terminal according to the channel switch information set, including: The channel switch information set is sent to the bridge device 200, so that the bridge device 200 opens or closes the configured second communication channel according to the channel switch information set; wherein the second communication channel is one of multiple communication channels.

It should be noted that the opening and closing of the second communication channel is soft processing, such as turning off the power amplifier or symbol channel, etc. in some In the embodiment, when the channel switch information set represents the switching state of the carrier channel, the second channel represents the carrier channel. When the channel switch information set represents the scheduling channel, such as slot channel and symbol channel, the second channel represents the scheduling channel. . The channel type of the second communication channel depends on the scheduling process in which the shutdown operation occurs. If it is a carrier shutdown detection process, the carrier channel is turned off. If it is a scheduling channel detection process, the scheduling channel is turned off or on.

It should be noted that in some embodiments, only the first communication channel can be closed or the second communication channel can be closed or opened. In other embodiments, both the first communication channel and the second communication channel can be closed. Off or on. In the embodiment of the present application, both the first communication channel and the second communication channel are selected to be closed or opened to achieve energy consumption control for all link nodes between the baseband processing unit 100 and the user terminal, and the control methods are richer. comprehensive.

It can be understood that the belonging data is obtained through the following steps: receiving the uplink reference signal sent from the user terminal through the remote radio frequency unit 300; comparing the uplink reference signal with the preset signal; based on the comparison result, establishing the relationship between the user-side device and the remote device. The association between the radio frequency units 300 obtains the corresponding belonging data of the user-side device. By proactively sending uplink reference information to the user terminal, the user terminal can make a more accurate judgment on ownership.

It should be noted that the generation of the belonging data may not be in the same cycle as the generation of the channel switch information set, or it may be within the same cycle. For example, for the carrier channel detection process, the corresponding generation of the belonging data will be generated accordingly in the same cycle of acquiring the belonging data. Channel switch information set; for scheduled channel detection, it is related to the belonging data, and its corresponding channel switch information set can use the belonging data in the carrier channel detection process, and based on the belonging data, it is passed in another polling cycle Periodic query scheduling data generation. In some embodiments, the above method of obtaining the belonging data is only applicable to obtaining the belonging data of the carrier channel detection. For the scheduling channel, the belonging data can be calculated and confirmed based on the scheduling data.

It should be noted that the uplink reference signal can be determined by periodic detection. For example, the remote radio frequency unit performs periodic blind detection to determine whether the user terminal has sent the uplink reference signal. In other embodiments, the uplink reference signal can be determined by the baseband processing unit in the downlink. The direction actively initiates a measurement, and the remote radio unit then receives upper and lower reference signals in response to that measurement.

It can be understood that, according to the comparison result, the association between the user-side device and the remote radio frequency unit 300 is established, and the corresponding attribution data of the user-side device is obtained, including: when the power of the upper and lower reference signals is greater than the power of the preset signal, on the user side The device information of the remote radio frequency unit 300 is added to the radio frequency belonging set of the device to obtain the belonging data.

It should be noted that the power of the preset signal can be dynamically adjusted. For indoor access systems, the same user terminal can be received by multiple RRUs. Therefore, in actual applications, adjustments can be made according to actual needs, thereby making the attribution of user terminals more accurate and energy consumption control more precise. .

Step S110 is to generate a channel switch information set corresponding to the belonging data according to the belonging data of at least one user terminal, including: in the first round During the polling cycle, generate a carrier channel switch information set corresponding to the belonging data based on the belonging data of at least one user-side device; and/or, during the second polling cycle, generate based on the belonging data of at least one user-side device. The scheduling switch information set corresponding to the belonging data. By setting different polling cycles to poll different communication channels, the current scheduling and operation status of the room access system can be obtained in real time, thereby further controlling energy consumption.

It should be noted that in some embodiments, periodic inspection can be set only for the shutdown and opening operations of the carrier channel to obtain the carrier channel switch information set, and the scheduling channel is not processed or the shutdown and opening of the scheduling channel is a trigger mode, etc.; In other embodiments, periodic inspection can be set only for the shutdown and opening operations of the scheduling channel to obtain the scheduling switch information set, and the carrier channel is not processed or the shutdown and opening operations of the carrier channel are triggered. In other embodiments, the shutdown and opening operations of the scheduling channel and the carrier channel can be enabled. The enabling triggering method can be manual configuration by the user or automatic triggering by setting a threshold. When the shutdown and opening operations of the scheduling channel are enabled, After that, the scheduling start will be generated in the second polling cycle. Off information set, when the off and on operation of the carrier channel is enabled, the carrier channel on and off information set will be generated in the first polling cycle.
